[0021] The base 1 is symmetrically provided with the fixed input assembly 2 and the sliding input assembly 3 (see the attached Figure 1 and 2 ).

[0022] The fixed input assembly 2 comprises a bearing seat 15, a workpiece support seat 17 and an input shaft 16; the base 1 is provided with the input shaft 16 through the bearing seat 15; the workpiece support seat 17 is mounted on the base 1 at one end of the input shaft 16; the other end of the input shaft 16 is connected with the corresponding transmission shaft 7 on the load gear box 4 through the torque sensor 11 and the coupling A 9.

[0025] The workpiece support seat 17 is mounted on the sliding plate 18 at one end of the input shaft 16; the other end of the input shaft 16 is connected with the corresponding transmission shaft 7 on the load gear box 4 through the torque sensor 11 and the coupling A 9 (see the attached Figure 1 and 5 ).

[0026] When the performance testing device needs to test two groups of workpieces 27, the workpieces 27 are installed on the workpiece support seat 17 of the sliding plate 18, so that the workpieces 27 are connected with the transmission shaft 7 through the input shaft 16, the torque sensor 11 and the coupling A9. If the performance testing device only needs to test one group of workpieces, the coupling A9 is loosened, and the sliding plate 18 is pushed backward through the operation handle 19, so that the input shaft 16 is separated from the transmission shaft 7 on the load gear box 4. In this way, only the fixed input assembly 2 is involved in the work to complete the performance test of a single workpiece.

[0027] The fixed input assembly 2 and one end of the sliding input assembly 3 are provided with the load gear box 4. The load gear box 4 is provided with the intermediate gear 6 through the load shaft 5. The intermediate gear 6 is provided with the transmission gear 8 through the transmission shaft 7 on both sides.

One end of the transmission shaft 7 is connected with the corresponding fixed input assembly 2 or sliding input assembly 3 through the coupling A9. The load motor 10 is installed on the base 1 at one end of the load gear box 4. The load motor 10 is connected with one end of the load shaft 5 through the torque sensor 11.

Figure 1 and 3 ).

[0028] The connecting assembly 14 includes the upper support seat 20, the lower support seat 22, the transmission sleeve 26 and the spline sliding shaft 25.

Figure 7 ).

[0029] In the working process of the performance testing device of the power steering motor, the load motor 10 can simulate the load torque of the power steering motor 27 through the torque sensor 11, the load shaft 5, the intermediate gear 6 and the transmission gear 8, and the load torque is transmitted to the corresponding workpiece 27 through the fixed input assembly 2 and the sliding input assembly 3. In this process, the automobile operation action can be simulated through the automobile steering wheel 13, the connecting assembly 14 and one end of the load shaft 5. In this way, the performance testing device of the power steering motor can simulate various stress conditions of the load motor 10 and complete the simulation experiment.

[0030] In the above process, the input shaft 16 can be switched out of contact with the transmission shaft 7 on the load gear box 4 by operating the operating handle 19 to push the slide plate 18 backward, so as to detect both groups of steering assist motors 27 or detect one group of steering assist motors 27.

[0031] The performance testing device for the steering assist motor is compact in structure and ingenious in design, and can realize single machine detection or double machine simultaneous detection according to needs, thereby solving the problem of low detection efficiency existing in the performance testing mode of the existing steering assist motor, and being particularly suitable for the needs of performance testing of the steering assist motor.
