    Fastener clamping and loosening system and associated clamping and unclamping methods
    The present invention relates to a clamping and loosening system of motor vehicle wheel fasteners.
    The present invention also relates to a clamping method and a method of loosening from said clamping and unclamping system.
    Such a system is capable of allowing the removal or fixing of a wheel on a vehicle.
    The fasteners of a wheel on the axle of a vehicle are generally formed by studs, nuts, bolts or the like.
    It is known to use tools such as cross keys to tighten or loosen manually and individually such fasteners.
    However, such manual tightening is not always suitable for satisfactorily tightening the fasteners. Indeed, for the wheel is fixed stably on the motor vehicle, the fasteners must be tightened with a tightening torque within a range set by the manufacturer. In particular, tightening above the limits set by the manufacturer may damage the fastener and the adjoining portions of the motor vehicle. Clamping below the limits set by the manufacturer may lead to progressive loosening of the fastening element when driving the motor vehicle and disconnection of the wheel relative to the motor vehicle. Tools for measuring the tightening torque during tightening exist.
    However, even with these tools, the tightening and loosening operation remains tedious and time consuming since it is necessary to actuate the fasteners individually one after the other. One of the aims of the invention is to propose a tightening and loosening system for clamping or loosening the fastening elements of a motor vehicle wheel to said motor vehicle in a stable and fast manner independently of the force of the wheel. 'user.

    The tightening and loosening system according to the invention makes it possible to tighten or loosen the fixing elements of the motor vehicle wheels as a function of the control signal generated by the control device. Thus, the clamping is no longer entirely manual since it is controlled by the control device. Such a system thus makes it possible to overcome the problems caused by a too weak tightening or a tightening too strong because of an erroneous appreciation of the user.
    In addition, such a system allows the simultaneous tightening and loosening and / or in one operation of several fasteners while applying a constant and minimal clamping force on the actuator.
    In addition, such a system is easy to use since it is at least partially automated by the presence of the control device and the displacement device.
    The tightening and unclamping system further comprises one or more of the following features: the system comprises a frame integral in rotation with the actuator, the frame comprising at least one rib, the second gear part being provided in the rib and movable in translation in the rib in a direction perpendicular to the main axis; - The displacement device comprises an electric motor arranged to move the second gear part between the engaged position and the disengaged position; the control device comprises a unit for measuring the tightening torque of each clamping element and / or the clamping force exerted on at least a portion of each first gear part, the control device being arranged to generate the control signal according to measurements made by the unit of measurement; the system comprises a plurality of second gear parts adjacent to one another, surrounding the clamping members, and defining a closed contour when the plurality of said second gear portions are in the engaged position; the system comprises at least four clamping elements, the number of second gear parts being chosen so that each second gear part in the engaged position is in contact with at most only one first gear part; the system comprises a housing, the actuator projecting from a first outer wall of the housing and the clamping elements protruding from a second outer wall of the housing, the second outer wall being opposite to the first wall; outside the main axis. The invention also relates to a method of clamping motor vehicle wheel fastening elements, said wheel being fixed to the vehicle by at least two fastening elements, from a system as described above, the method comprising the arrangement of each clamping element on a fastener element to be tightened, the actuation of the actuator so as to drive the second gear part in rotation, the holding of the second gear part in position; engaged and pivoting of said second gear portion on the first gear portions so as to partially tighten the set of fasteners to be clamped, and - moving and pivoting of the second gear portion between the gear position. engaged and the disengaged position so as to fully tighten the fasteners one after the other.
    The aforementioned clamping method further comprises a clamping method comprising: - the provision of each clamping element on a fastener element to be tightened, - the actuation of the actuator so as to drive each second gear part in rotation holding each second gear part in the engaged position and pivoting said second gear part onto the first gear parts so as to partially tighten the set of fasteners to be clamped, and - the movement and the successive pivoting of each second gear part between the engaged position and the disengaged position so as to fully tighten the fasteners one after the other.

    A tightening and loosening system 1 of motor vehicle wheel fasteners is illustrated in FIGS. 1-9.
    The fasteners are configured to attach a wheel to the axle of a motor vehicle, the wheel being fixed to the vehicle by at least two fasteners (not shown). The fasteners are, for example, studs, nuts, bolts or the like. In general, the tightening and loosening of these fastening elements is done by a rotation of the fastening elements about an axis which is substantially parallel to the axis of the axle and the axis of the wheel.
    The system 1 is adapted to actuate the fasteners to tighten or loosen said fasteners.
    In the embodiment illustrated in Figures 1 to 9, the system 1 comprises a housing 4, a frame 5 disposed in the housing 4 and an actuator 6 movable in rotation about a main axis A-A 'parallel to the axis of rotation of the fasteners.
    The system 1 further comprises at least two clamping elements 8. The clamping elements 8 are complementary to the fastening elements, each clamping element 8 carrying a first gear part 12.
    The system 1 also includes at least a second gear portion 16. The second gear portion 16 is complementary to each first gear portion 12 and is movable in a radial direction perpendicular to the main axis A-A. .
    The system 1 also comprises a device 18 for moving the second gear part 16 as a function of a control signal and a control device 20 for generating the control signal.
    The housing 4 is advantageously configured to contain all the elements of the tightening and loosening system 1. Thus, the system 1 is easily transportable.
    The shape of the housing 4 is, for example, cylindrical in diameter substantially similar to the internal diameter of a motor vehicle wheel. Thus, the housing 4 is particularly adapted to be fixed on the fastening elements of a motor vehicle wheel.
    As illustrated in Figures 1 to 3, the housing 4 comprises, in particular, a first outer wall 21 in the form of a disc and a second outer wall 22, opposite the first wall 21 relative to the main axis A-A 'and of similar shape to the first wall 21. The housing 4 further comprises a cylindrical side wall 25 joining the first outer wall 21 to the second outer wall 22.
    The first outer wall 21 is adapted to receive the actuator 6 as will be described later. In addition, the first wall 21 advantageously comprises gripping members 23 (visible in Figure 2) of the housing 4, for example handles, to facilitate the transport and positioning of the housing 4 on the fasteners.
    The second outer wall 22 is able to pass the clamping elements 8 as will be described in the following description.
    Apart from these elements, the other elements of the system 1 are masked and protected by the outer walls 21,22 and the side wall 25. The actuator 6 protrudes from the first outer wall 21 of the housing 4. The actuator 6 is operable by the user, that is to say, able to be rotated by the user. The system 1 is running when the actuator 6 is actuated by the user. According to the direction of rotation of the actuator 6, the system 1 is suitable for tightening or loosening the fastening elements. The actuator 6 is, for example, a stud, a nut, a bolt or others. The actuator 6 is, for example, operable from a tool commonly used to change the wheels of motor vehicles, such as a cross key.
    The clamping elements 8 are complementary to the fastening elements. Thus, each clamping member 8 can be attached to a wheel attachment member.
    The number of clamping elements 8 is equal to the number of fastening elements of a motor vehicle wheel. As illustrated in Figures 1 and 3 to 8, the clamping elements 8 are five in number for a wheel comprising five fasteners.
    The clamping elements 8 protrude from the second outer wall 22 of the housing 4. Advantageously, the clamping elements 8 are arranged on the second outer wall 22 so that each clamping element 8 can be engaged with a fastening element. distinct from the same wheel. The arrangement of the clamping elements 8 is therefore defined according to the arrangement of the fastening elements on a wheel.
    In the embodiment illustrated in Figures 1 to 9, each clamping element 8 comprises a first end 8A protruding outside the housing 4 and a second end 8B located inside the housing 4. The first end 8A carries a Female key complementary to the fasteners. The second end 8B is stud-shaped and carries a first gear portion 12.
    Thus, in the embodiment illustrated in Figures 1 to 9, the system 1 comprises five first gear parts 12, each of these first gear parts 12 being carried by a separate clamping element 8.
    In addition, each first gear portion 12 is disposed within the housing 4.
    Each first gear portion 12 is adapted to be rotated with respect to an axis parallel to the main axis A-A '.
    The first gear parts 12 are integral in rotation with the female wrenches carried by the corresponding clamping elements 8, thus making it possible to tighten or loosen the fastening elements fastened to the clamping elements 8.
    The first gear parts 12 are, for example, pinions extending in a radial plane perpendicular to the main axis A-A ', as illustrated in FIGS. 4 to 8.
    The frame 5 is disposed in the casing 4 as illustrated in FIGS. 4 to 8.
    The chassis 5 is rotatably connected to the actuator 6, that is to say that a rotation of the actuator 6 causes a rotation in the same direction of the chassis 5.
    The frame 5 comprises at least one rib 24 for receiving the second gear part 16. The rib 24 is, for example, a rib having a section in the form of an Aronde tail.
    The chassis 5 comprises as many ribs 24 as second gear parts 16. In the embodiment illustrated in FIGS. 1 to 9, the chassis 5 comprises at least nine ribs 24 for receiving the second gear part 16.
    The second gear portion 16 has, for example, a first portion 26 of complementary shape to the ribs 24 and a second portion 28 of complementary shape to the first gear portions 12. In the embodiment illustrated in FIGS. 9, the second portion 28 is notched to mesh with the first gear parts 12 in the form of sprockets.
    The second gear part 16 is rotatably connected to the actuator 6. The second gear part 16 is formed in the rib 24 of the frame 5, so as to be displaceable in translation in said rib 24 in a radial direction, perpendicular to the main axis A-A '.
    The second gear part 16 is thus movable between an engaged position (FIGS. 4, 5 and 6 for the second gear part 16A) and a disengaged position (FIG. 7 for the second gear part 16A). In the engaged position, the second gear portion 16 is adapted to engage a first gear portion 12, that is, the gear teeth of the first gear portion 12 are engaged with the second gear portion 28. of the second gear portion 16, and to rotate said first gear portion 12 so as to tighten or loosen at least one fastener attached to the clamping member 8 of said first gear portion 12. In the disengaged position, the second gear part 16 is spaced apart from the main axis A-A 'in a radial direction and can not come into contact with any of the first gear parts 12.
    In the embodiment illustrated in FIGS. 1 to 9, the system 1 advantageously comprises a plurality of second gear parts 16 adjacent to one another.
    Advantageously, the second gear parts 16 surround the clamping elements 8 and thus define, via their second portions 28, a closed crown-shaped contour when the plurality of said second gear parts 16 is in the engaged position.
    When the system 1 comprises a plurality of second gear parts 16, the number of second gear parts 16 is selected so that each second gear part 16 in the engaged position is in contact with at most only one first part of the gear unit. Thus, a second gear portion 16 can not simultaneously be in contact with two separate first gear parts 12.
    The displacement device 18 is able to move each second gear part 16 between the engaged position and the disengaged position following receipt of a control signal. Thus, the displacement device 18 is able to translate the second gear parts 16 in radial directions, perpendicular to the main axis A-A ', independently of one another in the ribs 24 of the frame 5.
    The displacement device 18 comprises at least one electric motor 30 arranged to move the second gear parts 16 between the engaged position and the disengaged position.
    The displacement device 18 comprises an electric motor 30 for each second gear part 16. Thus, in the embodiment illustrated in FIGS. 1 to 9, the displacement device 18 comprises nine electric motors 30 since the system 1 comprises nine second gear parts 16.
    As illustrated in FIGS. 8 and 9, the electric motors 30 are, for example, connected to the second gear parts 16 by means of rods 37, such as threaded rods received in threaded holes of the second gear parts 16. Thus, the motors 30 are able to drive in rotation the corresponding threaded rods 37, which makes it possible to move the second gear parts 16 radially by screwing or unscrewing the threaded rods into the threaded orifices of the second gear parts 16.
    The control device 20, illustrated in FIG. 10, is configured to generate a control signal for controlling the displacement device 18 and thus the change of position of the second gear parts 16 between the engaged position and the disengaged position.
    The control device 20 comprises a measuring unit 32 and a control unit 34. The measuring unit 32, illustrated in FIG. 8 and FIG. 10, is able to measure the tightening torque of each clamping element 8 and / or the clamping force exerted on at least a portion of each first gear portion 12. The measuring unit 32 comprises, for example, torque sensors 35 connected to each clamping element 8 to measure the tightening torque each clamp member 8 and / or measuring sensors 36 of a clamping force disposed in each first gear portion 12, for example in one or more gear teeth when the first gear parts 12 are gear wheels . An example of a sleeve-shaped torque sensor 35 and a measurement sensor 36 is illustrated in FIG. 8. The control unit 34, illustrated in FIG. 10, is arranged to generate the control signal in FIG. according to the measurements made by the measurement unit 32. The control unit 34 notably comprises a memory and a processor such as a microcontroller.
    The memory of the control unit 34 comprises, in particular, values of predetermined tightening torques and / or predetermined clamping forces relating to specific tightening states of the fastening elements. In particular, the memory comprises a first predetermined interval of tightening torques and / or clamping forces corresponding to a partial tightening of the fastening elements and a second predetermined interval of tightening torques and / or clamping forces corresponding to a tightening total of fasteners. The first predetermined interval depends, for example, on the make of the vehicle and the category of the vehicle. The second predetermined interval is, for example, preprogrammed by the user.
    The memory also comprises the relative position of each clamping element 8 and of each second gear part 16, as well as an order of tightening and loosening of the fastening elements as a function of the relative position of the clamping elements 8 .
    Alternatively, the measurement unit 32 includes a position sensor adapted to measure the position of each second gear portion 16 and the control unit 34 is configured to determine the movement of the second gear portions 16 as a function of the relative position of the second gear parts 16 with respect to the first gear parts 12.
    In the rest of the description and in the figures, the first gear parts 12 are differentiated from one another by the references "12A", "12B", "12C", "12D" and "12E" and the second parts 16 are differentiated from each other by the references "16A", "16B", "16C", "16D", "16E", "16F", "16G", "16H" and "161".
    The microcontroller is able to calculate, according to the measurements of the measurement unit 32 and the first and second predetermined intervals, the desired displacement of each second gear part 16 in order to rotate a first gear part 12 of a clamping member 8 and thereby tightening or loosening the corresponding fastening member by a predetermined tightening torque.
    The functional links between the measurement unit 32, the control unit 34 and the electric motors 30 are in particular illustrated in FIG.
    A method of clamping motor vehicle wheel fasteners using system 1 will now be described.
    Initially, the user has each clamping element 8 on a fastening element to be clamped on a motor vehicle wheel. This can be done in a single operation by appropriately positioning the system 1 and engaging the clamping elements 8 on the fasteners.
    Then, the user actuates the actuator 6 so as to rotate the frame 5 and the second gear parts 16. In particular, the user rotates the actuator 6 so as to allow the clamping of the elements of fixation. The actuation of the actuator 6 is, for example, carried out by means of a tool such as a tool conventionally used for tightening or loosening a motor vehicle wheel. The user continuously actuates the actuator 6 in the rest of the tightening process. The measuring unit 32 measures the tightening torque of each clamping member 8 and / or the clamping force of each first gear portion 12. The fastening elements initially being untightened or very loosely tightened, the tightening torques measured, respectively the measured clamping forces are substantially damaged.
    When the values measured by the measurement unit 32 are strictly lower than the minimum value of the first predetermined interval, the control unit 34 generates a control signal enabling the set of second parts to be switched on or held in place. gear 16.
    The displacement device 18 holds the second gear parts 16 in the engaged position, as illustrated in FIG. 4.
    The second gear parts 16 then pivot on the first gear parts 12, which rotates these first gear parts 12 and the corresponding clamping elements 8 and allows for partial tightening of the fasteners.
    Then, when the measuring unit 32 measures at least a tightening torque of a clamping member 8 and / or at least a clamping force of a first gear portion 12 equal to or greater than the maximum value of the first predetermined interval or when all the measured values are within the first predetermined interval, the control unit 34 generates a new control signal transmitted to the displacement device 18.
    The displacement device 18 then successively moves the second gear parts 16 between the engaged position and the disengaged position so that only one second gear part 16 is engaged at a time and a first gear part 12 is engaged. a first clamping element 8 pivots until the corresponding fastening element is fully tightened, that is to say that the measured torque and / or the measured force for this first clamping element 8 is included broadly in the second predetermined interval.
    The displacement device 18 then similarly moves the second gear parts 16 to rotate each first gear portion 12 one after the other until all the fasteners are fully tightened.
    For example, as illustrated in FIGS. 5 and 6, the second gear portion 16A is initially engaged to pivot the first gear portion 12A. Then, as shown in FIG. 7, if the tightening torque of the corresponding clamping element 8 and / or the clamping force of the first gear portion 12A is in the second predetermined interval, the second part of gear 16A is disengaged and the second gear portion 161 adjacent to the second gear portion 16A is engaged to pivot the same first gear portion 12A and continue clamping the associated fastener. The second gear portions are moved in the same manner until the fastener clamped by the clamping member 8 corresponding to the first gear portion 12A is fully tightened. The process is then repeated to rotate one after another the first gear parts 12B, 12C, 12D and 12E to fully tighten the fasteners one after the other.
    Thus, the clamping method comprises two main steps: a step of partially clamping all the fasteners at the same time and a total clamping step of each fastener one after the other. These two steps make it possible to limit the effort of the user to actuate the actuator 6 and thus make the system 1 usable whatever the physical capabilities of the user.
    Similarly, a method of loosening motor vehicle wheel fasteners using system 1 will now be described.
    Initially, the user has each clamping element 8 on a fastener to be loosened of a motor vehicle wheel.
    Then, the user actuates the actuator 6 so as to rotate the chassis 5 and the second gear parts 16. In particular, the user rotates the actuator 6 so as to allow the loosening of the elements of fixation. The user continuously actuates the actuator 6 throughout the rest of the loosening process. The measuring unit 32 measures the tightening torque of each clamping element 8 and / or the clamping force of each first gear part 12.
    When the value measured by the measurement unit 32 is strictly greater than the maximum value of the first predetermined interval, the control unit 34 generates a control signal transmitted to the displacement device 18. The displacement device 18 then successively moves the second gear portions 16 between the engaged position and the disengaged position such that only one second gear portion 16 is engaged at a time and the first gear portion 12 of a first clamping member 8 pivots to the corresponding fastening element is partially loosened, i.e. the measured torque and / or the measured force for this first clamping element 8 is broadly included in the first predetermined interval.
    The displacement device 18 then similarly moves the second gear parts 16 to pivot one after the other each first gear part 12 until all the fasteners are partially loosened.
    Then, when the measuring unit 32 measures that all the tightening torques of the clamping elements 8 and / or the clamping forces of the first gear parts 12 are less than or equal to the maximum value of the first predetermined interval, the control unit 34 generates a new control signal transmitted to the displacement device 18.
    The displacement device 18 then moves or holds the set of second gear parts 16 in the engaged position.
    The second gear parts 16 then pivot on the first gear parts 12, which rotates these first gear parts 12 and the corresponding clamping elements 8 and allows the fasteners to be completely loosened. The total loosening corresponds, for example, to a tightening torque and / or to a substantially zero clamping force.
    Thus, the loosening process also comprises two main steps: a step of partially loosening the fasteners one after the other and a step of loosening the fasteners at the same time. These two steps can still limit the effort of the user to actuate the actuator 6 and thus make the system 1 usable regardless of the physical capabilities of the user.
    The system 1 is therefore easy to use since the user only has access to the casing 4 and the only actions required of the user are to arrange the clamping elements 8 on the fastening elements and then to actuate the device. actuator 6 in a continuous movement until a predetermined tightening torque or a predetermined clamping force is reached.
    Alternatively, the actuator 6 is automated, that is to say, it is rotated by a motor and its use requires no effort on the part of the user.
