Description

Technical Field

[0001] This utility model belongs to the field of hub motor testing technology, and in particular relates to a motor electromagnetic parking performance testing device. Background Technology

[0002] The electromagnetic parking brake function uses the de-energization of the electromagnet in the hub motor to bring the brake pads into contact with the rotor, thus stopping the vehicle when parked. When the vehicle is powered on, the electromagnet is de-energized, separating the brake pads from the rotor and releasing the braking restriction. The selection of electromagnetic parking brake pads made of different materials requires simulation testing of the hub motor's electromagnetic parking brake to choose the most cost-effective and reliable option. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a testing device that uses static friction to simulate and test the electromagnetic parking performance of a hub motor.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a motor electromagnetic parking performance testing device, comprising a lower frame, an upper frame, a lifting mechanism, a support platform, a clamping structure, a test platform, a slide cylinder, and a control module. The upper frame is fixedly installed on the lower frame, the lifting mechanism is fixedly installed on the lower frame, the clamping structure is fixedly installed on the upper frame, the support platform is fixedly installed on the execution end of the lifting mechanism, the cylinder body of the slide cylinder is fixedly installed on the support platform, the test platform is fixedly installed on the slider of the slide cylinder, and the lifting mechanism and the slide cylinder are both connected to the control module via circuitry.

[0005] Preferably, the lifting mechanism is a telescopic cylinder, the cylinder body of which is fixedly mounted on a support platform, and the support platform is fixedly mounted on the top of the piston rod of the telescopic cylinder. The telescopic cylinder is connected to a pressure station through a pipeline and a first solenoid valve, and the first solenoid valve is connected to a control module through a circuit.

[0006] Preferably, two linear slide rails in the left and right directions are fixedly installed on the top surface of the support platform, and a slider is fixedly installed on the bottom surface of the test platform, with the slider slidably mounted on the linear slide rails.

[0007] Preferably, a groove is provided on the bottom surface of the test platform, the slide cylinder is located in the groove, and the left-right dimension of the groove is greater than the stroke of the slide cylinder.

[0008] Preferably, an anti-slip rubber pad is screwed and fixedly installed on the top surface of the test platform.

[0009] Preferably, the system also includes a telescopic guide rod, the upper and lower ends of which are fixedly connected to the support platform and the lower frame, respectively.

[0010] Compared with the prior art, the advantages of this utility model are: after the shaft of the hub motor is clamped and fixed, when the slide cylinder applies a force to the test platform to the left or right, it can observe whether the tire of the hub motor rotates. This can simulate the performance of the electromagnetic brake pads acting on the rotor of the hub motor when the tire of the hub motor is parked. By setting up a lifting mechanism, it is not only convenient to clamp the shaft of the hub motor on the clamping structure, but also to meet the testing needs of electromagnetic brake pads of hub motors of various sizes.

[0013] Figure 2 yes Figure 1 Enlarged structural diagram at point M. Detailed Implementation

[0014] The present invention will now be described in detail with reference to specific embodiments:

[0015] like Figure 1 and Figure 2 The device shown is a test equipment for testing the electromagnetic parking performance of a motor, including a lower frame 1, an upper frame 2, a lifting mechanism 3, a support platform 4, a clamping structure 5, a test platform 6, a sliding cylinder 8, and a control module. The upper frame 2 is fixedly installed on the lower frame 1, the lifting mechanism 3 is fixedly installed on the lower frame 1, the clamping structure 5 is fixedly installed on the upper frame 2, the support platform 4 is fixedly installed on the execution end of the lifting mechanism 3, the cylinder body of the sliding cylinder 8 is fixedly installed on the support platform 4, and the test platform 6 is fixedly installed on the slider of the sliding cylinder 8. The lifting mechanism 3 and the sliding cylinder 8 are both connected to the control module through circuits. The sliding cylinder 8 is connected to a pressure station through pipelines and a second solenoid valve. The pressure station and the second solenoid valve are connected to the control module through circuits.

[0016] The lifting mechanism is a telescopic cylinder 3. The cylinder body of the telescopic cylinder 3 is fixedly installed on the support platform 4. The support platform 4 is fixedly installed on the top of the piston rod of the telescopic cylinder 3. The telescopic cylinder 3 is connected to the air pressure station through pipelines and a first solenoid valve. The first solenoid valve is connected to the control module through an circuit. The telescopic cylinder 3 has the advantages of large lifting force and low operating cost.

[0017] Two linear slide rails 7 in the left and right directions are fixedly installed on the top surface of the support platform 4, and a slider 71 is fixedly installed on the bottom surface of the test platform 6. The slider 71 is slidably installed on the linear slide rails 7. Through the guiding effect of the linear slide rails 7 and the slider 71, the straightness of the test platform 6 when moving left and right can be improved.

[0018] A groove 60 is provided on the bottom surface of the test platform 6, and the slide cylinder 8 is located in the groove 60. The left-right dimension of the groove 60 is greater than the stroke of the slide cylinder 8. By placing the slide cylinder 8 in the groove 60, the gap height between the test platform 6 and the support platform 4 can be reduced, and the stability of the test platform 6 when moving left and right can be improved.

[0019] An anti-slip rubber pad 61 is screwed and fixedly installed on the top surface of the test bench 6. The anti-slip rubber pad 61 can increase the friction between the test bench 61 and the tire of the hub motor 10. The anti-slip rubber pad 61 can be removed and replaced separately after it wears out.

[0020] It also includes a telescopic guide rod 31, the upper and lower ends of which are fixedly connected to the support platform 4 and the lower frame 1, respectively. Through the guiding effect of the telescopic guide rod 31, the straightness of the support platform 4 when moving up and down can be improved.

[0021] The shaft of the hub motor 10 is clamped and fixed by the clamping structure 5. The piston rod of the telescopic cylinder 3 extends upward, pushing the combination of the support platform 4, the test platform 6, and the slide cylinder 8 downward until the top surface of the test platform 6 contacts the tire of the hub motor 10. After the hub motor 10 is de-energized and stops, the slide cylinder 8 is driven to apply a force to the left or right on the test platform 6, so that the test platform 6 applies a relative static friction force to the tire of the hub motor 10. When the slide cylinder 8 applies a force to the left or right on the test platform 6 repeatedly, observe whether the tire of the hub motor 10 rotates. The air pressure of the air station on the slide cylinder 8 can be adjusted through the control module to adjust the pushing and pulling force of the slide cylinder 8, thereby adjusting the relative static friction force applied by the test platform 6 to the tire of the hub motor 10.
