    [0001] The invention relates to a brake drive unit and a brake system having such a brake drive unit.
    [0002] Known from DE 10 2010 040 097 A1 a braking system for motor vehicles comprises a brake pedal to actuate a brake decoupling unit with a main brake cylinder, an electro-hydraulic pressure supply device in the form of a hydraulic cylinder/piston arrangement, the piston of which can be driven by an electric motor through an intercalated rotation and translation gear mechanism, and a pressure modulating unit having an inlet valve and a valve wheel brake output for setting individual wheel brake pressures. In this case, the brake system has a modular structure; that is, that the main brake cylinder is arranged in a first module, the pressure supply device is arranged in a second module, and the valves for brake pressure modulation and the wheel brakes disconnect and connection valves for and brake master cylinder or to or from the pressure supply device are arranged in a third module. All modules are implemented as independent units. In the braking system the axis of the electric motor, the longitudinal axis of the pressure supply device and the longitudinal axis of the brake master cylinder are arranged parallel to each other.
    [0003] It is an objective of the present invention to provide a compact brake drive unit for a brake-by-wire braking system for motor vehicles.
    [0004] This objective is achieved according to the invention by a brake drive unit.
    [0005] The invention is based on the concept of arrangement of the first arrangement of cylinder and piston actuable by the vehicle driver, the pressure supply device and the valve arrangement in the same housing, the electric motor shaft of the pressure supply device being disposed substantially perpendicular to the longitudinal axis of the first cylinder and piston arrangement.
    [0006] An advantage of the invention lies in a compact integration of brake actuation and brake pressure modulation in one module. Weight savings, simple manufacturing capability and good connectivity of electrical and hydraulic connections are thus possible. Additionally, the orthogonal arrangement allows for a short overall length of the brake drive unit, which is advantageous for good characteristics in an accident situation, so that the risk of injury to the vehicle driver is reduced. The integrated compact layout also makes possible improved possibilities for adapting the braking drive unit to different vehicle packages.
    [0007] The longitudinal axis of the second cylinder and piston arrangement of the pressure supply device is also preferably disposed substantially perpendicularly to the longitudinal axis of the first cylinder and piston arrangement. It can thus be achieved that the housing extension in the direction of travel (direction of the longitudinal geometric axis of the first cylinder and piston arrangement) is substantially determined by the minimum length of the first cylinder and piston arrangement, and does not substantially exceed said minimum length. Especially and preferably, the geometric axes of the electric motor and the second cylinder and piston arrangement are arranged in alignment. An additional gear mechanism, for example a rotation and rotation gear in addition to the rotation and translation gear of the pressure supply device, is then unnecessary.
    [0008] According to a development of the invention, the brake drive unit includes a simulation device that communicates a pleasant brake pedal feel to the vehicle driver in brake-by-wire mode, this brake pedal simulator being arranged at least partially in the housing. The longitudinal axis of the brake pedal feel simulator is disposed substantially perpendicularly to the longitudinal axis of the second cylinder and piston arrangement in order to obtain a compact structure. Especially preferably, the brake pedal feel simulator is hydraulically implemented and includes a third cylinder and piston arrangement having at least one simulator piston. The effect of the brake pedal feel simulator can be advantageously turned on and off by means of a simulator release valve.
    [0009] The hydraulic connections of the brake drive unit are preferably arranged on the same side face of the brake drive unit housing where the electric motor is arranged. By arranging the hydraulic and electric motor connections perpendicular to the longitudinal geometric axis of the first cylinder and piston arrangement, the space requirement for the brake drive unit installed in the direction of travel is lower.
    [00010] According to a preferred embodiment of the brake actuation unit according to the invention, it includes a brake pedal actuation path detection device which is also integrated at least partially in the housing. The brake pedal actuation path detection device is especially and preferably formed by a path sensor that detects the actuation piston path.
    [00011] The brake drive unit preferably includes a pressure sensor that detects the pressure of the first cylinder and piston arrangement and an additional pressure sensor that detects the pressure of the pressure supply device, the pressure sensors also being integrated at least partially to the engine.
    [00012] The electric motor is preferably fixed to a first side face of the housing, the geometric axis of the electric motor being disposed substantially perpendicular to the first side face. Consequently, the first side face is guided approximately parallel to the longitudinal geometric axis of the first cylinder and piston arrangement. Especially and preferably, the size of the first side face is dimensioned so that the electric motor, or its attachment side, can be completely sealed to the first side face of the housing. Since the hydraulic connections of the brake drive unit are preferably arranged on the same side face of the brake drive unit housing as the electric motor in order to minimize the space requirement of the brake drive unit, the hydraulic connections, by For example, for connecting the wheel brakes, they are advantageously arranged on the first side face.
    [00013] According to a preferred embodiment of the brake drive unit according to the invention, the valve arrangement is arranged on a second side face of the housing opposite the electric motor.
    [00014] The brake pedal actuation path detection device and/or the pressure sensors are preferably arranged on the second side face.
    [00015] An electronic control and regulation unit having a control unit housing disposed on the second side face opposite the electric motor is preferably provided in order to enable a simple electrical or magnetic connection between the valve arrangement and/or the device. brake pedal actuation path detection and/or the pressure sensors and the electronic control and regulation unit. The housing of the control unit therefore especially and preferably covers at least a part of the valve arrangement and/or the brake pedal actuation path detection device and/or the pressure sensors. The control unit housing preferably extends beyond the second side face of the housing in at least one direction in order to enable space-saving attachment of an electrical connection element.
    [00016] The electronic control and regulation unit preferably serves to activate the pressure supply device and the valve arrangement, which is why the output signals of the pressure sensors and the brake pedal actuation path detection device are especially and preferably supplied for the electronic control and regulation unit.
    [00017] The electrical connections between the pressure supply device, in particular the electric motor, and the electronic control and regulation unit preferably pass through the housing.
    [00018] According to a preferred embodiment of the brake drive unit according to the invention, at least one electrical connection element is advantageously arranged injection molded in the control unit housing and extends adjacent to a third side face of the housing opposite the push rod. This arrangement of the connecting element saves space and enables an electrical connection, eg via a plug-in connector, parallel to the third side face and therefore in front of the housing in the direction of travel. Especially and preferably, the electrical connecting element extends parallel to the geometric axis of the electric motor, since sufficient access to the brake drive unit is available in that direction due to the electric motor.
    [00019] A pressure medium reservoir under atmospheric pressure is preferably attached directly to a fourth side face of the housing. Alternatively, a hydraulic connection for a reservoir of pressure medium under atmospheric pressure is provided on the fourth side face of the housing.
    [00020] According to a development of the invention, an additional electrical connection element, which serves especially and preferably to supply electrical energy to the electronic control and regulation unit, is arranged in the control unit housing and extends between the housing and the pressure medium reservoir. The connecting element therefore advantageously extends adjacent to the fourth side face of the housing. The connecting element is thus space-savingly arranged and is protected by the housing and the pressure medium reservoir. In order to achieve an even smaller brake actuating unit, a recess through which the connecting element can pass is provided in the housing and/or in the pressure medium reservoir. The additional electrical connection element also extends especially and preferably parallel to the geometric axis of the electric motor. Alternatively, it is preferable that the additional connecting element extends through the housing or through the pressure medium reservoir.
    [00021] In order to keep the extension of the brake actuating unit as small as possible in the direction perpendicular to the longitudinal geometric axis of the first cylinder and piston arrangement, the second cylinder and piston arrangement of the pressure supply device preferably projects at least partially from the accommodation. Especially and preferably, the designed part of the second cylinder and piston arrangement is covered by the control unit housing or extends through the control unit housing, where the necessary general installation space is again reduced.
    [00022] For the simple attachment of the brake drive unit to the motor vehicle, the housing of the brake drive unit preferably includes on its side face on the push rod side a fastening element, advantageously a fastening plate, by means of which the housing can be mechanically secured to a bulkhead of the motor vehicle.
    [00023] The invention also relates to a braking system having a brake drive unit according to the invention. The brake actuation unit is preferably used in a braking system for motor vehicles which, in a "brake-by-wire" mode, can be activated by the vehicle driver and independently of the vehicle driver, is preferably operated in the brake-by-wire mode and can be operated in at least one "fall-back" mode, in which only operation by the vehicle driver is possible.
    [00024] Additional preferred embodiments of the invention are apparent from the embodiments and from the following description with reference to the schematic figures in which: Figure 1 illustrates a first illustrative embodiment of a brake drive unit according to the invention in a first view; Figure 2 illustrates the first illustrative embodiment of Figure 1 in a second view perpendicular to the first view; Figure 3 illustrates a second illustrative embodiment of a brake actuation unit according to the invention in a first view; and Figure 4 illustrates the second illustrative embodiment of Figure 3 in a second view perpendicular to the first view.
    [00025] Figures 1 and 2 schematically represent a first illustrative mode of a brake drive unit according to the invention for a brake-by-wire type motor vehicle braking system. The brake actuation unit 1 comprises a hydraulic piston and cylinder arrangement 3 which can be actuated by a vehicle driver by means of a push rod (pedal rod) 2 and has a actuation piston (not shown) which is displacedly guided in the housing 10 of the brake drive unit along the longitudinal geometric axis 30 of the first cylinder and piston arrangement and delimits a hydraulic pressure chamber to which the wheel brakes (not shown) of the vehicle braking system The engine can be fixed by means of hydraulic connections. The cylinder and piston arrangement 3 is, for example, a master cylinder. The cylinder and piston arrangement 3 serves, for example, to allow pressure to be applied to the wheel brakes by the driver in a braking system fall-back mode where the wheel brakes are hydraulically connected to the pressure chamber of the brake arrangement. cylinder and piston 3. The longitudinal axis 30 is arranged substantially parallel to the direction of travel X of the motor vehicle.
    [00026] An electrically controllable pressure supply device 6, in the form of a second hydraulic piston and cylinder arrangement 12, is disposed at least partially within the housing 10, the piston of the cylinder and piston arrangement 12 being displaceable by a motor electric 7 by means of a gear mechanism of rotation and translation 9 along the longitudinal axis 31 of the second cylinder and piston arrangement 12. In a brake-by-wire mode of the brake system, the wheel brakes can be actuated by means of the pressure of the pressure supply device 6. For this purpose the electric motor 7 can be activated in accordance with a brake pedal actuation. The electromechanical actuator comprising the electric motor 7 and the rotation and translation gear mechanism 9 performs a translational movement of the piston of the second cylinder and piston arrangement 12. In the example, the gear mechanism 9 is in the form of an actuator. ball screw or a cylindrical screw driver.
    [00027] Additionally, a valve arrangement 4 comprising a plurality of valves 41, 42, 43 is disposed at least partially in the housing 10, by means of that valve arrangement 4 the individual wheel brake pressures can be configured and can be disconnected or connected from the first cylinder and piston arrangement 3 or from the pair to the pressure supply device 6.
    [00028] The first cylinder and piston arrangement 3, the valve arrangement 4 and the pressure supply device 6 are arranged wholly or at least partially within the single common housing 10, the geometric axis 33 of the electric motor 7 of the device pressure supply 6 being disposed perpendicularly or almost perpendicularly to the longitudinal axis 30 of the first cylinder and piston arrangement 3.
    [00029] The electric motor 7 is fixed to the housing 10 directly to the side face 20 of the housing 10. The minimum extension of the side face 20 is configured so that the fixing end face of the electric motor 7 can be completely sealed to the housing 10 .
    [00030] The geometric axis 31 of the second cylinder and piston arrangement 12 is also arranged orthogonally or nearly orthogonally to the longitudinal geometric axis 30 of the first cylinder and piston arrangement 3, i.e. along the Y direction. For example, the axis 33 of the electric motor 7 and the axis 31 of the second cylinder and piston arrangement are arranged in alignment.
    [00031] The brake drive unit 1 additionally includes an electronic control and regulation unit 5 (ECU) having a control unit housing 11, and a pressure medium reservoir (brake fluid container) 8 under atmospheric pressure .
    [00032] The pressure medium reservoir 8 can be fixed directly to the housing 10. Alternatively, at least one connection to the pressure medium reservoir 8 can be arranged in the housing 10. The pressure medium reservoir 8 or the connections of the pressure medium reservoir 8 are advantageously arranged on the upper side face 24 (in the Z direction above the side faces 20, 21, 22, 23) of the housing 10.
    [00033] The electronic control and regulation unit 5 serves to activate the pressure supply device 6, and the valve arrangement 4 and is arranged on the side face 21 of the housing 10 opposite the electric motor 7. The electrical connections between the motor The electric 7 and the control and regulation unit 5, for example, for activating the electric motor or for transmitting signals (sensor), advantageously extend through the housing 10 in order to protect the electrical connections.
    [00034] The valve arrangement 4 is advantageously also arranged on the 21 side of the housing 10 opposite the electric motor 7, so that a simple electrical or magnetic connection between the valve arrangement 4 and the control and regulation unit 5 is possible. All or at least part of valve arrangement 4 is covered by control unit housing 11.
    [00035] In order to detect the actuation of the brake pedal, the brake actuation unit 1 includes a path sensing arrangement (brake pedal actuation path detection device) 15 (for example, a sensor of path or position) for detecting the actuation of the brake pedal or the push rod 2 or the first cylinder and piston arrangement 3. The sensor arrangement 15 is advantageously integrated in whole or in part to the housing 10 and arranged on the side face 21 of housing 10. This enables a simple electrical or magnetic connection between the travel sensor arrangement 15 and the control and regulation unit 5. The travel sensor arrangement 15 is covered, for example, by the control unit housing 11.
    [00036] Additionally, a pressure sensor arrangement (not shown) is arranged in the housing 10. The pressure sensor arrangement includes, for example, at least one pressure sensor to detect a pressure of the first cylinder and piston arrangement 3 and a pressure sensor for sensing a pressure from the pressure supply device 6. Additional pressure sensors for sensing pressures in the brake circuits of the wheel brake circuits are optionally present. The pressure sensors are advantageously arranged in parallel between the valves 41, 42, 43 of the valve arrangement 4. Additionally, the pressure sensor arrangement is advantageously covered by the control unit housing 11.
    [00037] Additionally, the brake drive unit 1 also includes a travel sensor arrangement (for example, a travel sensor or position or angle sensor, not illustrated) to detect a position of the electric motor 7 or the piston of the machine. second cylinder and piston arrangement 12. For example, a rotor position sensor serving to detect the rotor position of the electric motor 7 is provided. Such a travel sensor arrangement is also integrated in whole or in part with the housing 10 and is arranged on the side face 21 of the housing 10. The path sensor arrangement is advantageously covered by the housing of the control unit 11.
    [00038] The output signals from the pressure sensor arrangement of the brake pedal actuation path detection device 15 and the rotor position sensor are supplied to the control and regulation unit 5.
    [00039] The housing 10 has an adapter plate (not shown) for mechanical attachment to the bulkhead, in the example, on the side face 22 of the housing 10 on the push rod side. The first cylinder and piston arrangement 3 extending in the direction of travel X within the housing 10 is therefore arranged orthogonally or nearly orthogonally to the vehicle bulkhead in the installed state of the brake drive unit 1.
    [00040] In the example, a part of the cylinder and piston arrangement 12 of the pressure supply device 6 protrudes from the housing 10 and is covered by the control unit housing 11, where a further reduction in installation space is achieved. . Alternatively, the cylinder and piston arrangement 12 may also extend through the control unit housing 11.
    [00041] The hydraulic connections 14 of the brake drive unit 1, for example, for the connections of the wheel brakes, are arranged on the side face 20 of the housing where the electric motor 7 is also arranged. In this position, therefore, the hydraulic connections 14 do not lead to any significantly greater installation space requirement of the brake drive unit in the Y direction.
    [00042] The electronic control and regulation unit 5 with its control unit housing 11 is arranged on the side face 21 of the housing 10. In the example, the control unit housing 11 extends beyond the side face 21 in the X direction.
    [00043] One or more electrical connection elements 17 are provided, for example, by injection molding, in the control and regulation unit 5 or in the housing 11 thereof. In the example, the connecting elements are in the form of sockets 17, 18 for receiving corresponding plug-in elements. The electrical connection elements 17, 18 are arranged in the example in the region of the control unit housing 11 extending beyond the side face 21. The electrical connector 17 serves, for example, to connect a data connection or bus to the signal transmission to another control unit or to connect to a CAN bus. The connecting element 18 is suitable, for example, to supply electrical current to the control and regulation unit 5.
    [00044] In the example, the connecting elements 17, 18 must be connected to the correspondingly designed housing 11 of the control device 5 in front of the housing 10 (in the direction of travel X). The plug-in direction of the connecting elements 17, 18 is aligned in a direction parallel to the geometric axis of the electric motor 33 (Y direction). The connecting elements 17, 18 are therefore arranged to the side of the side face 23 and below the brake fluid reservoir 8, and the plug-in direction is parallel to the side face 23 (facing the viewer in figure 2) .
    [00045] The brake drive unit 1 advantageously includes a brake pedal feel simulator 16 which communicates a pleasant brake pedal feel to the vehicle driver in brake-by-wire mode. The brake pedal feel simulator 16 extends all or part of the housing 10. Alternatively, the brake pedal feel simulator can be configured as an independent module that can be attached to the housing 10. The longitudinal axis 32 of the brake pedal feel simulator 16 is disposed substantially perpendicularly to the longitudinal axis 31 of the second cylinder and piston arrangement 12 and parallel to the longitudinal axis 30 of the first cylinder and piston arrangement 3 .
    [00046] The brake pedal feel simulator 16 is advantageously implemented hydraulically with at least one simulator piston displaceably guided in a cylinder. For example, the brake pedal feel simulator 16 includes at least one simulator piston, a hydraulic simulator chamber that is connected or connectable to a pressure chamber of the first cylinder and piston arrangement 3, and an elastic element (by example, a spring).
    [00047] The effect of the brake pedal feel simulator 16 can be advantageously turned on and off by means of a simulation release valve.
    [00048] As a result of the illustrative arrangement of the cylinder and piston arrangement 3, the pressure supply device 6, the valve arrangement 4, the control and regulation unit 5, the hydraulic connections 14 and the electrical connection elements 17 , 18, the maximum extension of the housing 10 in the direction of travel (X direction) is substantially determined by the minimum length of the cylinder and piston arrangement 3.
    [00049] A second illustrative mode of a brake drive unit according to the invention is schematically represented in figures 3 and 4. The second illustrative mode broadly corresponds to the first illustrative mode. Thus, the brake actuation module 1' includes a first cylinder and piston arrangement 3, e.g. a main cylinder, actuable by a push rod 2, a valve arrangement 4 comprising a plurality of valves. 41, 42, 43, an electrically controllable pressure supply device 6 with a second cylinder and piston arrangement 12, an electric motor 7 with a rotation and translation gear mechanism 9, an electronic control and regulation unit 5 , a brake pedal feel simulator 16 and a pressure medium reservoir 8. The cylinder and piston arrangement 3, the valve arrangement 4 and the pressure supply device 6 are arranged wholly or at least partially within a single common housing 10. The geometric axis 33 of the electric motor 7 of the pressure supply device 6 is disposed substantially perpendicularly to the longitudinal axis 30 of the first cylinder arrangement. o and piston 3.
    [00050] The relative orientation or arrangement of the first cylinder and piston arrangement 3, valve arrangement 4, pressure supply device 6 (second cylinder and piston arrangement 12 and electric motor 7), electronic control and regulation unit 5, Brake pedal feel simulator 16, hydraulic connections 14, brake actuation path detection device 15 and pressure medium reservoir 8 of the second illustrative embodiment also substantially correspond to the arrangement and orientation according to the first illustrative embodiment. For example, the electric motor 7 is arranged on the side face 20 of the housing 10 and the control and regulation unit 5 on the opposite side face 21.
    [00051] In the example, in the deviation from the first illustrative mode, the control unit housing 11 extends beyond the side face 21 in the X direction and in the Z direction. The electrical connection elements 17 and 18' are arranged, for example, in an injection molded way, in the control and regulation unit 5 or in its housing 11. The arrangement of the electrical connection element 17, which serves, for example, to connect a data connection or bus for signal transmission to another unit of control or for connection to a CAN bus, corresponds to the arrangement as in the first illustrative mode. The injection molded connecting element 18', which is suitable for supplying electrical current to the control and regulation unit 5, is arranged in the example in the region of the control unit housing 11 projecting beyond the side face 21 in the Z direction and is arranged or runs between the pressure medium reservoir 8 and the housing 10 (towards the spectator in figure 4, parallel to the geometric axis of the electric motor 33). The plug-in direction of the connecting element 18' is guided in the direction parallel to the geometric axis of the electric motor 33 (Y direction). The connecting element 18' is therefore arranged between the side face 24 and the brake fluid container 8, and the plug-in direction is parallel to the side face 24.
    [00052] To allow the connecting element 18' to pass through, in the example a recess in the housing 10 and a recess in the pressure medium reservoir 8 are present.
    [00053] The two-dimensional extension of the control and regulation unit 5 or its housing 11 is somewhat larger in the example than the corresponding side face 21 of housing 10, so that in figure 4, the housing unit control 11 arranged behind the housing 10 can be seen in a phantom view in the region of the recess in the housing 10, between the housing 10 and the pressure medium reservoir 8 and in front of the housing 10.
    [00054] According to an illustrative modality that is not illustrated, the connecting element for the supply of electric current, injection molded in the control and regulation unit 5 or its housing 11, is arranged or projects through housing 10 or through pressure medium reservoir 8 parallel to electric motor axis 33. To allow the plug-in connection to pass through, a recess is provided in housing 10 or reservoir 8.
