[0034] Specifically, when using the testing device, first, wheel hub motor is stably placed in the upper of support table 20, ensure its position stable, prevent displacement in subsequent testing process, at this time, electric push rod 6 is driven by its output end, so that slide 7 moves horizontally along specific track. In the sliding process of slide 7, the bottom connected sliding block 4 is smoothly slid on the outer wall of slide rail one 3, in the movement process of slide 7, in addition to driving sliding block 4 to move along slide rail one 3, the other side of slide 7 is also connected with cylinder 8. The piston of cylinder 8 is driven to stretch and retract under the action of gas pressure, further pushes connecting plate 9 and support seat 11 to move longitudinally, support seat 11 drives the tester 12 at the bottom to reach predetermined test position. Tester 12 ensures the accuracy and repeatability of test data through its sensor, when tester 12 is above test position, connecting plate 9 starts to move down through the control of cylinder 8, gradually drives support seat 11 and tester 12 to move down, until tester 12 contacts wheel hub motor surface to test, so that the test position can be fine-tuned to adapt to different types or different specifications of wheel hub motor test requirements.
