Description

Technical Field

[0001] This utility model relates to a dual-motor combined type test support device, belonging to the field of motor testing tooling technology. Background Technology

[0002] Currently, type testing is required for new traction motor products. To support these type tests, a support device is used. Existing support devices typically support only one side of the motor, meaning the device supports one mounting side of the motor, which is then suspended for testing.

[0003] Low-floor vehicles have more compact motors, and the structure of the traction motors installed in low-floor vehicles differs significantly from other traction motors. The traction motor unit in a low-floor vehicle consists of two traction motors connected by bolts at their non-drive ends. Therefore, testing requires a docking test between the two motors. Existing single-motor type test support devices cannot meet the type test support requirements for dual-motor combined traction motor units.

[0004] Compared to single-motor suspension supports, the biggest challenge of dual-motor docking supports is ensuring that the coaxiality of the two motors mounted on the support is highly consistent, and that the motor shafts of the two motors mounted on the support are on the same axis. Utility Model Content

[0005] The technical problem to be solved by this utility model is: how to make the motor shafts of two motors installed facing each other on the same straight line.

[0006] To address the above problems, the technical solution proposed by this utility model is as follows:

[0007] A dual-motor combined type test support device includes a main base plate and support frame 1 and support frame 2 facing each other on the main base plate. Support frame 1 has a base plate 1 fixed on the main base plate and a vertical plate 1 fixed on the base plate 1. Support frame 2 has a base plate 2 fixed on the main base plate and a vertical plate 2 fixed on the base plate 2. The facing sides of vertical plate 1 and vertical plate 2 are respectively provided with motor mounting position 1 and motor mounting position 2 for mounting motor 1 and motor 2. Motor mounting position 1 has a shaft hole 1 corresponding to motor shaft 1 of motor 1. Motor mounting position 2 has a shaft hole 2 corresponding to motor shaft 2 of motor 2. The center lines of shaft hole 1 and shaft hole 2 are on the same straight line.

[0008] In the middle of the main seat plate, there is a longitudinally arranged upward protruding linear guide rail of equal width. The bottom surfaces of both seat plate one and seat plate two are provided with linear track grooves that can fit into the linear guide rail. The linear track grooves of seat plate one and seat plate two are respectively engaged on the linear guide rail and can slide on the linear guide rail.

[0009] In the middle of the main seat plate, there is a longitudinally arranged linear track groove. The bottom surfaces of both seat plate one and seat plate two are provided with downwardly protruding linear guide rails that can fit against the groove wall of the linear track groove. The linear guide rails of seat plate one and seat plate two are respectively engaged in the linear track groove and can slide in the linear track groove.

[0010] Both the first and second seat plates are provided with waist-shaped bolt holes, and the main seat plate below the waist-shaped bolt holes is provided with threaded holes. The first and second seat plates are fixed to the main seat plate by bolts through the waist-shaped bolt holes and the threaded holes.

[0011] An inclined brace connected to the seat plate is provided on the front and rear sides of the first upright plate, and an inclined brace connected to the seat plate is provided on the front and rear sides of the second upright plate. Beneficial effects

[0018] The present invention will be further described below with reference to the accompanying drawings: Example 1

[0019] like Figure 1 , 2As shown, a dual-motor combined type test support device includes a main base plate 3 and support frames 1 and 2 facing each other on the main base plate 3. Support frame 1 has a base plate 101 fixed on the main base plate 3 and a vertical plate 102 fixed on the base plate 101. Support frame 2 has a base plate 201 fixed on the main base plate 3 and a vertical plate 202 fixed on the base plate 201. The facing sides of vertical plate 102 and vertical plate 202 are respectively provided with motor mounting positions 1021 and 2021 for mounting motor 8 and motor 9. Motor mounting position 1021 has a shaft hole 1022 corresponding to the motor shaft 801 of motor 8. Motor mounting position 2021 has a shaft hole 2022 corresponding to the motor shaft 901 of motor 9. The axis lines of shaft hole 1022 and shaft hole 2022 are on the same straight line 10. In application, one end of motor 8 and one end of motor 9 are fixed on motor mounting positions 1021 and 2021 of vertical plate 102 and vertical plate 202, respectively, and motor shaft 801 and motor shaft 901 are aligned with their respective shaft holes 1022 and 2022. In this way, motor shaft 801 and motor shaft 901 can be placed on the same straight line, which meets the requirements of the dual-motor combination type test.

[0020] In the middle of the main base plate 3, there is a longitudinally arranged, upwardly protruding linear guide rail 4 of equal width. The bottom surfaces of both base plate 101 and base plate 201 are provided with linear track grooves 5 that can fit against the linear guide rail 4. The linear track grooves 5 of base plate 101 and base plate 201 are respectively engaged with the linear guide rail 4 and can slide on the linear guide rail 4. In this way, when testing motors of different specifications and adjusting the spacing is required, as long as support frame 1 or support frame 2 slides along the linear guide rail 4 to the appropriate position and is then fixed, it can be ensured that the center lines of the shaft holes 1022 and 2022 of both can always be on the same straight line 10.

[0021] Both seat plate 101 and seat plate 201 are provided with waist-shaped bolt holes 6. The main seat plate 3 below the waist-shaped bolt holes 6 is provided with threaded holes. Seat plate 101 and seat plate 201 are fixed to the main seat plate 3 by bolts 601 through the waist-shaped bolt holes 6 and threaded holes. In this way, the support frame 1 or support frame 2 can be finely adjusted back and forth on the main seat plate 3 without adding threaded holes to the main seat plate 3 over a short distance.

[0022] An inclined brace 7 connected to the seat plate 101 is provided on the front and rear sides of the upright plate 102, and an inclined brace 7 connected to the seat plate 201 is provided on the front and rear sides of the upright plate 202, so as to ensure that the upright plate 102 and the upright plate 202 are perpendicular to the main seat plate 3. Example 2

[0023] like Figure 3 As shown, the difference between this embodiment and the first embodiment is that: in the middle of the main seat plate 3, there is a longitudinally arranged linear track groove 5, and the bottom surfaces of the first seat plate 101 and the second seat plate 201 are provided with downwardly protruding linear guide rails 4 that can fit against the groove wall of the linear track groove 5. The linear guide rails 4 of the first seat plate 101 and the second seat plate 201 are respectively engaged in the linear track groove 5 and can slide in the linear track groove 5.

[0024] The above embodiments are only used to describe the present invention more clearly, and should not be regarded as limiting the scope of protection covered by the present invention. Any equivalent modifications should be regarded as falling within the scope of protection covered by the present invention.
