Description

Technical Field

[0001] This utility model is a test bench for a new energy vehicle transmission, belonging to the field of new energy vehicles. Background Technology

[0002] The automotive transmission is the core of a car, a machine that converts mechanical power. It has numerous internal components and a complex structure. As the car moves, the transmission's posture changes with road conditions, affecting the flow of lubricating oil and the lubrication of the bearings. To simulate the lubricating oil conditions under different transmission postures, a test bench is needed that can simulate various road conditions, especially extreme conditions that cannot be replicated in road tests.

[0003] For example, the new energy vehicle transmission test bench with patent number CN201820613184.2 describes that the support base and the carrier frame can slide on the base plate, which can drive the input shaft of the transmission and the motor shaft to slide and align with each other, and then connect with a coupling.

[0004] However, existing manufacturers have different designs and specifications. The size of the input shaft needs to be matched with specific gearboxes and engines to ensure the efficiency and reliability of power transmission. Furthermore, the different sizes of existing new energy vehicles result in different gearboxes, leading to different models of gearboxes and thus different input shaft sizes. As a result, the input shaft and motor shaft are not matched, making it difficult to align the two when sliding the input shaft and motor shaft, which leads to unstable connection of the subsequent coupling. Therefore, this application proposes a new energy vehicle gearbox test bench with more comprehensive position adjustment. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a test bench for new energy vehicle transmissions.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] A test bench for a new energy vehicle transmission includes a base, on which a support frame and a support seat for supporting the transmission are slidably mounted. The support seat has a hollow interior and a lifting assembly is provided inside. The lifting assembly is connected to a drive motor, which is located above the support seat. The base has two adjusting assemblies connected to the corresponding support frame and support seat. The support frame has a notch through which the input shaft of the transmission passes. The motor shaft of the drive motor is connected to a disassembly shaft via a flange. The disassembly shaft is connected to the input shaft of the transmission via a coupling.

[0008] Furthermore, each of the adjustment components includes two fixed plates fixed on the base, one of which is fixed with a reducer and a forward / reverse motor. The output end of the forward / reverse motor is connected to the reducer, and the output end of the reducer is connected to a lead screw located between the fixed plates.

[0009] Furthermore, a threaded block is threaded onto the lead screw, and the threaded block is fixed to the bottom end of the bearing frame and the support base. A bearing is fitted onto the other end of the lead screw, and the bearing is fixed to another fixed plate. A traction rod that slides through the threaded block is also fixed between the fixed plates.

[0010] Furthermore, a transverse slide and a longitudinal slide are fixedly provided on the base, and four pulley assemblies are fixedly provided at the bottom of both the bearing frame and the support base. Each pulley assembly includes a grooved slider with a groove, and a rotating rod is rotatably arranged inside the groove of the grooved slider.

[0011] Furthermore, both the transverse slide and the longitudinal slide are provided with sliding grooves, the rotating rod is slidably disposed in the sliding groove, and four support pulleys are installed at the bottom end of the grooved slider when it rotates, the support pulleys are slidably disposed on the top surface of the base.

[0012] Furthermore, the lifting assembly includes a dual-axis lead screw and a lifting plate rotatably disposed inside the support base. Both ends of the dual-axis lead screw are threaded with auxiliary thread blocks. Each auxiliary thread block has a hinge rod hinged to its two side walls. The top of the lifting plate is fixed with four fixing plates. The other end of each hinge rod is hinged to the corresponding fixing plate.

[0013] Furthermore, a secondary positive and negative motor connected to the dual-axis lead screw is fixedly installed on the outer wall of the support base, and four through rods are fixedly installed at the top of the lifting plate. The top of the through rods slides through the support base and is fixed at the bottom of the support base.

[0014] Furthermore, the flange consists of two flanges, which are respectively fixed to the corresponding disassembly shaft and the motor shaft of the drive motor, and are secured with bolts and nuts.

[0015] The beneficial effects of this utility model are:

[0016] The carrier and support base of this application can slide on the base, which can adapt to different specifications of gearboxes and has a wider range of applications. Because manufacturers' designs and specifications may vary, the size of the input shaft needs to be matched with specific gearboxes and engines to ensure the efficiency and reliability of power transmission. Therefore, input shafts of different sizes exist.

[0017] Adjust the position of the corresponding carrier and support on the base by adjusting the components, so that the disassembly shaft indirectly connected to the motor shaft of the drive motor is better aligned with the input shaft of the gearbox, and then connected with a coupling.

[0018] The height of the drive motor on the top of the support can be adjusted by the lifting component, thereby adjusting the position of the disassembly shaft indirectly connected to the motor shaft, so as to better ensure the mutual alignment of the disassembly shaft and the input shaft, and finally connect them with a coupling.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a test bench for a new energy vehicle transmission, including a base 1, on which a support frame 2 and a support seat 3 for supporting the transmission are slidably mounted. The support seat 3 is hollow inside and has a lifting component inside. The lifting component is connected to a drive motor 4, which is located above the support seat 3. The base 1 has two adjustment components, which are connected to the corresponding support frame 2 and support seat 3. The support frame 2 has a notch 5 through which the input shaft of the transmission passes. The motor shaft of the drive motor 4 is connected to a disassembly shaft 7 with a flange. The disassembly shaft 7 is connected to the input shaft of the transmission via a coupling.

[0027] See Figure 1 Each adjustment component includes two fixed plates 8 fixed on the base 1. One of the fixed plates 8 is fixed with a reducer 9 and a forward / reverse motor 10. The output end of the forward / reverse motor 10 is connected to the reducer 9. The output end of the reducer 9 is connected to a lead screw 11 located between the fixed plates 8. A threaded block 12 is threaded onto the lead screw 11. The threaded block 12 is fixed to the bottom end of the support frame 2 and the support seat 3. A bearing 13 is fitted onto the other end of the lead screw 11. The bearing 13 is fixed on the other fixed plate 8. A traction rod that slides through the threaded block 12 is also fixed between the fixed plates 8. The forward / reverse motor 10 drives the reducer 9 to rotate, thus driving the lead screw 11 to rotate. When rotating, the threaded block 12 moves horizontally on the lead screw 11, ultimately causing the support frame 2 and the support seat 3 to slide on the base 1. This allows for adaptation to different specifications of gearboxes and different input shaft sizes, thus enabling more comprehensive adjustment of the position of the support frame 2 and the support seat 3, ensuring more precise alignment of the disassembly shaft 7 and the input shaft, and subsequent connection with a coupling.

[0028] See Figure 1-2The base 1 is fixedly provided with a transverse slide 14 and a longitudinal slide 15. The bottom ends of the support frame 2 and the support base 3 are each fixedly provided with four pulley assemblies. The pulley assembly includes a grooved slider 16 with a groove. A rotating rod 17 is rotatably arranged inside the groove of the grooved slider 16. The transverse slide 14 and the longitudinal slide 15 are each provided with a sliding groove 18. The rotating rod 17 is slidably arranged in the sliding groove 18. When the bottom end of the grooved slider 16 rotates, four support pulleys 19 are installed. The support pulleys 19 are slidably arranged on the top surface of the base 1. When the support frame 2 and the support base 3 move, the grooved slider 16 moves. The rotating rod 17 rotates and slides in the groove of the grooved slider 16, and the support pulleys 19 slide on the top surface of the base 1, ensuring that the support frame 2 and the support base 3 move with less effort. The support pulleys 19 are steel wheels.

[0029] See Figure 1-3 The lifting assembly includes a dual-axis lead screw 20 rotatably disposed inside the support base 3 and a lifting plate 23. Both ends of the dual-axis lead screw 20 are threaded with auxiliary threaded blocks 21. Each auxiliary threaded block 21 has a hinged rod 22 hinged to its two side walls. Four fixing plates 24 are fixed to the top of the lifting plate 23. The other end of each hinged rod 22 is hinged to a corresponding fixing plate 24. An auxiliary positive and negative motor 25 connected to the dual-axis lead screw 20 is fixed to the outer wall of the support base 3. Four through rods 26 are fixed to the top of the lifting plate 23. The top of each through rod 26 slides through the support base 3 and is fixed to the bottom of the support base 3. The flange consists of two flanges 27. The flange 27 is fixed to the corresponding disassembly shaft 7 and the motor shaft of the drive motor 4. The flange 27 is fixed with bolts and nuts. The auxiliary positive and negative motor 25 drives the double-shaft lead screw 20 to rotate. Therefore, the two auxiliary threaded blocks 21 generate relative movement on the double-shaft lead screw 20, thereby driving the hinged lifting plate 23 to generate lifting movement. The lifting plate 23 is connected to the support base 3 with the through rod 26, and finally drives the support base 3 to complete the lifting and lowering. The disassembly shaft 7 and the input shaft are aligned with each other and finally connected with the coupling. The design of the flange 27 allows the disassembly shaft 7 to be replaced with a disassembly shaft 7 of the same size as the input shaft. The installation of the replaced disassembly shaft 7 and the input shaft is more convenient with the coupling. The coupling also needs to be replaced with a coupling of different sizes.

[0030] In practical operation, the carrier frame 2 and support seat 3 of this application can slide on the base 1, which can adapt to different specifications of gearboxes and has a wider range of applications. Because the design and specifications of manufacturers may vary, the size of the input shaft needs to be matched with a specific gearbox and engine to ensure the efficiency and reliability of power transmission. Therefore, there are input shafts of different sizes. By adjusting the position of the corresponding carrier frame 2 and support seat 3 on the base 1, the disassembly shaft 7 indirectly connected to the motor shaft of the drive motor 4 is better aligned with the input shaft of the gearbox. Subsequently, it is connected with a coupling. The height of the drive motor 4 on the top of the support seat 3 can be adjusted by the lifting component, thereby adjusting the position of the disassembly shaft 7 indirectly connected to the motor shaft, so as to better ensure the mutual alignment of the disassembly shaft 7 and the input shaft. Finally, it is connected with a coupling.

[0031] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
