    专利说明:

    [0001] [0001] The present invention relates to an electric drive module for a vehicle, in particular, utility vehicle with electric drive and / or hybrid drive, according to the preamble of patent claim 1.
    [0002] [0002] Efficient drive modules for utility vehicles usually have high voltage batteries (for example, lithium battery packs and ions or accumulators), which need to be cooled to avoid harmful excess temperatures. In general, it is already known to have at least the battery pack on rapidly interchangeable drive modules (for example, as insertion units). From US patent 2009/0236478 A1, a support frame for a vehicle battery is generally known. The support frame can be suspended with hook elements laterally on a longitudinal frame of the utility vehicle.
    [0003] [0003] The components needed especially for the hybrid drive or for the battery drive, for example, high voltage battery, electronic inverter, as well as, water cooling system for the electronic inverter and for the high voltage battery, are typically housed as separate components from each other, independent on supports, which are bolted, for example, to the longitudinal frame. In the same way, it is known to directly mount the components individually on the longitudinal frame of the utility vehicle.
    [0004] [0004] The task of the invention is to provide a drive module for a utility vehicle with electric and / or hybrid drive, which is developed and improved with respect to the possibilities of use and use.
    [0005] [0005] The task is solved by means of the characteristics of the patent claim 1. Preferred improvements are disclosed in the subordinate claims.
    [0006] [0006] The invention is based on the reality that, the components necessary for the hybrid and electric drive, then, can only be subjected to a function test when they are installed in the utility vehicle. In view of this background, according to the invention, the necessary components for the hybrid drive and electric drive can already be assembled externally before installation in the utility vehicle, as a construction unit totally in condition to operate, in such a way that, for example, the above function test can be intended even before installation on the utility vehicle. Correspondingly, according to the part that characterizes patent claim 1, the drive module is arranged in the support frame as an autonomous unit with the battery pack, with electrical transformers such as electronic inverters and power transformers. direct current, at least, from an electrical connection interface and from a cooling system with at least one heat exchanger (cooler), with conductors from the cooling medium and with a feed pump. In turn, the support frame can be maintained or placed on the vehicle structure. In this way, the drive module can be completely pre-assembled, tested in its functions and finally incorporated into the motor vehicle. For repairs it can be disassembled and exchanged or repaired simply and quickly. For different types of vehicles, the drive modules can be made available and optionally used with different power. When used in the utility vehicle, possibly in the unloaded state, it can be exchanged without problems with a pre-loaded unit and, thus, can enable an extended hybrid or electric drive.
    [0007] [0007] In order to keep oscillations away from the driving operation, the support frame can be maintained or placed on the structure, preferably by inserting elastic spring bearings, whereby the drive module and, in particular, the battery pack are supported decoupled from oscillation.
    [0008] [0008] In addition, the cooling system can be a liquid cooling system with at least one water and air heat exchanger and a geodesically high cooling medium compensation container, which are attached to the frame support. The thermostatic electric supply pump, and / or controlled by means of a control device and eventually a fan, are externally energized, therefore, they can be tested autarchically.
    [0009] [0009] In an advantageous improvement of the invention, the support frame can be composed of longitudinal, transverse and vertical struts like cage, on which are mounted at least one battery pack or at least one heat exchanger, the cooling medium conductors, the compensation vessel, the feed pump and the electrical transformers such as the electronic inverter and the direct current transformer with at least one connection interface. The cage-like support frame is very manageable in the assembly technique, and offers torsionally rigid reception for aggregates and integrated devices.
    [0010] [00010] In a utility vehicle, as a particularly preferred arrangement, the support frame can be mounted or can be mounted on one of the longitudinal beams of the utility vehicle structure laterally, between a front axle and a rear axle, resulting in good accessibility side, on the one hand, and a particularly protected arrangement of the drive module in the event of frontal or rear collisions of the vehicle.
    [0011] [00011] In another embodiment of the invention, a support structure can be mounted or assembled on the longitudinal beam, into which the support frame of the drive module can be inserted. This creates a double protection, formed through the two frame structures, in particular, for the battery pack and simplifies the assembly or replacement of the drive module.
    [0012] [00012] In order to obtain a particularly stable construction against torsion and of low cost, the support structure can have U-shaped side frames, which are fixedly connected to each other through several transverse spars, and which through the transverse spars are connected in the direction of an open frame structure towards the longitudinal beam and up / down, in particular, the side frames directly adjacent to the longitudinal beam can be fixed on the longitudinal beam, and the support frame can be placed over the support structure.
    [0013] [00013] In addition, for the greatest reinforcement of the support structure, in particular, against the forces acting underneath (for example, collision forces) between an upper transverse stringer and a lower transverse stringer of the support structure is fixed to the side frames, respectively, a transverse stringer diagonally slanted outward and downward from the longitudinal beam.
    [0014] [00014] In another advantageous embodiment of the invention, moreover, it is suggested that the longitudinal side members of the support structure are composed of several vertical side members to form a flexural resistant longitudinal frame, which in connection with the cross members serves as protection against side collision with support frame, for the drive module that is inside the support structure.
    [0015] [00015] The drive module can be executed in a particularly suitable arrangement of the function point with two battery packs in the support frame, which are superimposed, with a gap between them being formed, at least, in which they are positioned. the feed pump, cooling medium conductors, electrical conductors and components, etc. In this case, moreover, at least one of the chillers in the cooling system can be arranged on the laterally external support frame, away from the longitudinal beam of the structure, and can be positioned behind the longitudinal frame, which serves as collision protection. In the case of two battery packs used, for improved cooling, a cooler may be provided for each battery pack, the coolers of which are connected with the feed pump separated by supply tubes and return tubes for cooling medium supply. .
    [0016] [00016] In a simple structural way and with particularly advantageous assembly, the upper longitudinal struts of the support frame can be suspended on a four-point support on the upper cross members of the support structure through projected sections, by means of interchangeable spring-loaded bearings . In addition, the longitudinal frame of the support structure, which serves as collision protection, can be connected with the cross members with a rigid corner, using additionally fixed upper and lower junction plates.
    [0017] [00017] Finally, on the upper longitudinal struts of the support frame and / or on the longitudinal beam of the structure, a work platform can be fixed, which presents stepping surfaces, and / or which receives function points, which covers the package of upper battery protecting and, at the same time, prepares a favorable ergonomic access area for operating devices of the utility vehicle.
    [0018] [00018] An example of a preferred embodiment of the invention is explained in more detail below, with the aid of the attached drawing. They are shown:
    [0019] [00019] In figure 1 as a general arrangement, a utility vehicle with a support frame fixed to its longitudinal beam, in which a municipal electric drive module can be inserted, with a support frame;
    [0020] [00020] In figure 2, the support frame fixed to the longitudinal beam, in spatial representation, which is composed of lateral frames, cross members, a longitudinal frame that is external and junction plates;
    [0021] [00021] In figure 3, the cage-like support frame of the drive module is composed of longitudinal stringers, cross members and vertical stringers, of a retention console that projects laterally into the, and with the upper and lower battery pack inserted;
    [0022] [00022] In figure 4 the complete drive module, which can be inserted in the support frame, with support frames, battery packs, electrical transformers and liquid cooling systems;
    [0023] [00023] In figure 5, the drive module in the state inserted in the support frame, and with work platform, which forms stepping surfaces, seated on the utility vehicle; and
    [0024] [00024] In figure 6 an area of the utility vehicle section according to figure 1, with support frame mounted on the utility vehicle, with drive module inserted and work platform seated on the utility vehicle.
    [0025] [00025] Figure 1 schematically depicts a tractor 1 with driver's cab 1a and seat plate 2 of an articulated vehicle as a utility vehicle, which features a hybrid drive, which consists of an internal combustion machine as the first source of fuel. drive and at least one electrical machine as a second drive source. The drive units can be of the known construction type and are therefore not shown.
    [0026] [00026] The drive energy for the electric machine (s) is stored in at least one drive module 3, which is arranged as a municipal unit laterally on tractor 1 (see figure 6; on figure 1 drawn in the disassembled state).
    [0027] [00027] Furthermore, in the tractor support structure 4, between the front axle 5 and the rear axle 6 (only the wheels are evident, respectively) and behind the driver's cab 1a in the first (or both) of the two longitudinal beams 7, 8 massive, a support frame 9 is yet to be described, in which the electric drive module 3 is inserted.
    [0028] [00028] Figure 2 shows the support frame 9 in detail, mounted on the longitudinal beam of the utility vehicle 8, as well as, with the drive module 3 omitted. The support frame 9 is made up of side frames 10, 11 in the shape of a U, which are in its corners, of two transverse spars 12, 13 on each transverse side and of an external longitudinal frame 14. Between the transverse struts 12, 13, respectively, a transverse stringer 15, aligned diagonally downwards outwards, increases, in particular, the stiffness of the support structure 9 in the Z direction.
    [0029] [00029] On the front sides of the side frames 11, the longitudinal frame 14 is fixed to the bending-proof. This frame is produced from transverse struts 16 and vertical struts 17, and serves as protection against side collision in the event of a side collision with another vehicle or the like.
    [0030] [00030] The support structure 9 is screwed or riveted to the longitudinal beam 8 with side frames 10 adjacent to its front sides, fixedly with the longitudinal beam 8. The connection points between the side frames 10, 11 and the longitudinal and cross members of the steel support structure 9 are partly welded, screwed or riveted. The support structure 9, in connection with the longitudinal beam 8, forms a continuous closed frame, which according to figure 2 is executed open downwards and upwards, and is additionally reinforced in the outer corner areas by junction plates 18 upper and lower. The junction plates 18 can be screwed, preferably, after the suspension of the drive module 3 in the support frame 3.
    [0031] [00031] Figures 3 and 4 show the drive module 3, which has a support frame 19, approximately square, in the form of a cage (compare with figure 3), which is composed of longitudinal struts 20, 21 upper and lower , with vertical struts 23 arranged in their corners and, on the one hand, a diagonal strut 24 that reinforces. The said struts are preferably made of light metal profiles, and are fixedly connected to each other by means of screw, solder and / or rivet connections.
    [0032] [00032] In the support frame 19, two battery packs 25 are integrated with a multiplicity of lithium and ion cells (not shown). As can be seen from figure 3, these are arranged overlapping with an interval between them, and are screwed with the longitudinal, transverse and vertical struts 20, 21 and 23, in such a way that they form support elements with the support frame 19. The height of the battery packs 25 and the vertical gap is approximately one third of the entire height of the support frame.
    [0033] [00033] On the side of the support frame 19, facing the longitudinal beam 8 (in the assembled state), and in the area of the free gap, evident in figure 3, between the battery packs 25 is formed a retention console 26 formed of several struts (without reference numbers), projecting inwards, which supports an electronic inverter 27 with an integrated direct current transformer 28 (figure 4) which, not shown, are connected with at least one interface connection, for the electrical connection to the on-board network of the utility vehicle 1, and via corresponding electrical conductors are connected with the battery packs 25.
    [0034] [00034] The drive module 3 (figure 4) features an autarchic liquid cooling system. The liquid cooling system consists, in essence, of conduits of cooling medium (not visible) of the battery packs 25, and around the electronic inverter 27 with direct current transformer 28. In addition, the cooling system of liquid is connected with two coolers 30, through various cooling medium conductors, such as water and air heat exchangers, with an electrically driven feed pump 31 and a cooling medium compensation container 32. Eventually, behind the coolers 30, between the battery packs 25, an electric blower can also be integrated to transport cold air through the chillers 30.
    [0035] [00035] In the case of corresponding control, the feed pump 31 drives the cooling medium circuit and feeds the cooling medium (for example, a mixture of water and glycol) through a suction conductor 34 of the two coolers 30 for the pressure conductor 33. Starting from the pressure conductor 33, the cooling medium is circulated in the circuit under passage in the electrical devices, for example, battery or electronic inverter. In the suction conductor 34 the compensation container 32 located above is geodesically connected, via a supply line 36.
    [0036] [00036] As shown in figures 4 and 5, in the mounted state of the drive module (figure 5), the two coolers 30 are positioned on the side of the vehicle 1 that is external, and behind the longitudinal frame 14, which serves as protection to the collision, of the support frame 9 that supports it must be understood that, in the support frame 19 of the drive module 3, several fixing strips, etc. are provided, which serve, for example, for the fixing of the feed pump 31, of the compensation container 32, etc. and for reasons of simplification they will not be described in detail.
    [0037] [00037] The drive module 3 is manufactured as a pre-assembly unit. Battery packs 25, electric transformers 27, 28, the complete cooling system with the various cooling media conductors, the coolers 30, the supply pump 31, the compensation container 32, etc., are filled in. with cooling medium and aerated. After this pre-assembly, the drive module 3 is thoroughly tested for the electrical and thermal capacity and charge status of the battery packs 25, and are tested for the sealing of the cooling system.
    [0038] [00038] After completing these tests outside of vehicle 1, the drive module 3 is suspended from above with the support frame 19 on the support frame 9 attached to the vehicle 1.
    [0039] [00039] In addition, the upper longitudinal struts 20 (compare figures 3 and 4) have extended sections 20a, which extend beyond the contour of the support frame 19, which by means of the interleaving of shock absorbers or bearings 37 rubber bands are fixed , on a four-point support (see also figure 2), on the transverse side members 12 of the support frame and are fixed by screw connections.
    [0040] [00040] Additionally, in addition, rubber elastic support bearings 38 (figure 5) can also be provided, lateral between the cross members 15 or 13 located deeper in the support frame 9 and the vertical struts 23 of the support frame 19 After suspension or assembly of the drive module 3, this module is electrically connected, via the connection interface (not shown), to the vehicle's on-board network 1 and is ready for operation.
    [0041] [00041] Above the support frame 19 of the drive module, in a way not shown in detail, a large area profiled work platform 39 is attached, which serves as a stepping area and / or as a support for function parts during the utility vehicle 1 and, at the same time, acts as another protective reinforcement cover, for the drive module 3.
