Abstract

The invention discloses a method and device of testing the performance of a mechanical rotary spare wheel up-down regulator. The spare wheel up-down regulator comprises a rotating shaft and a winding lifting part. One end of the winding lifting part is fixed to and wound around the rotating shaft, and the other end of the winding lifting part is the free end connected with a weight test piece. The method comprises the steps of controlling a motor to drive the rotating shaft to rotate and enabling the weight test piece to ascend or descend; when the weight test piece ascends or descends by a unit length, controlling the motor to stop driving the rotating shaft; detecting whether any component in the spare wheel up-down regulator is deformed or clamped; when no deformation or clamping is detected, carrying out the above steps, and when the weight test piece ascends or descends by the unit length of a certain number, determining that the performance of the spare wheel up-down regulator is qualified. According to the scheme, the performance of the spare wheel up-down regulator can be tested, and therefore whether produced spare wheel up-down regulators are qualified can be determined.

Description

technical field [0001] The invention relates to the field of transportation, in particular to a method and device for testing the performance of a mechanical rotary spare tire lifter. Background technique [0002] The spare wheel is a common part of the car. The spare tire of a general car is placed inside the compartment, while the spare tire of a large vehicle, such as a truck, is usually placed under the vehicle. For large vehicles like this, because the spare tire is higher than the ground position and the weight is very heavy, it is very difficult to manually disassemble, so a spare tire lifter is needed to lift the spare tire to realize the taking of the spare tire. The performance of the spare tire lifter directly affects the safe setting and use of the spare tire, thereby affecting the safety of the vehicle. However, there is no test method for the performance of the spare tire lifter in the prior art, and it is impossible to determine whether the produced spare ti...
