The invention discloses a new energy automobile motor test bench, and belongs to the field of detection devices. The test bench comprises a base, a test device and a commutation device, wherein the base includes a support rod; the test device includes a load motor; and the commutation device includes a commutation motor, a commutation disc, a fixed wheel, a plurality of steering wheels, chains andinstallation plates, the commutation motor is arranged on the base, the fixed wheel is fixedly installed on the support rod, the fixed wheel is coaxially arranged with an output shaft of the commutation motor, the plurality of steering wheels are uniformly arranged along the circumferential direction of the fixed wheel, the steering wheels are rotatably arranged on the commutation disc, each steering wheel is connected with the fixed wheel through the chain, and the installation plates are horizontally fixed on the steering wheels respectively. It can be ensured that the installation plates are always horizontal when the commutation disc is rotated. Since there are a plurality of installation plate, the installation of other motors can be carried out while one motor is tested, thereby enabling the installation and disassembly time and the test time to be overlapped, making full use of the working hours, and improving the test efficiency.
Description
technical field [0001] The invention relates to the field of detection devices, in particular to a new energy vehicle motor test bench. Background technique [0002] In the new energy vehicle drive motor test, the main drive is the mutual drag between the load motor and the motor under test. There are mainly two forms in the prior art. The first form is to set up an elastic coupling and a high-speed bearing box between the motor under test and the accompanying motor, and the transmission direction is the accompanying motor-torque sensor-coupling- Bearing housing - spline tooling - motor under test. The second form is to connect a rigid shaft between the motor under test and the motor under test. The two ends of the rigid shaft are splined, which can be directly connected to the two motors. The transmission direction is the motor under test-torque sensor-spline tooling - The motor under test. [0003] All the transmission mechanisms in the prior art have disadvantages. Fo...
