Abstract

The invention relates to the field of testing machines, in particular to a suspension spring torsional moment testing machine, which includes a working table. A Z-direction loading device and an X-direction loading device are mounted on the working table. The Z-direction loading device comprises a Z-direction drive device, a Z-direction transmission mechanism, a Z-direction guide rail, a Z-direction moving member, a Z-direction displacement measurement device and the like. The X-direction loading device comprises an X-direction drive device, an X-direction transmission mechanism, an X-direction guide rail, an X-direction moving member, an X-direction displacement measurement device, a Y-direction guide rail, a Y-direction moving member and the like. A fixed shaft is disposed on the working table. The fixed shaft is mounted vertically in a movable manner on the working table. The invention further provides a suspension spring torsional moment testing method. The invention can be used for simulating an actual use state of a suspension spring, testing the torsional moment of the suspension spring, thus enabling the torsional moment of the suspension spring to stay in a standard range, and improving the comfort and safety of a vehicle.

Description

technical field [0001] The invention relates to the field of testing machines, in particular to a suspension spring torsional moment testing machine and a method for testing the suspension spring torsional moment. Background technique [0002] Suspension is a general term for all force-transmitting connection devices between the frame (or load-bearing body) and the axle (or wheel) of a car. Its function is to transmit the force and torque acting between the wheel and the frame, and Buffer the impact force transmitted to the frame or body from the uneven road surface, and reduce the vibration caused by it, so as to ensure that the car can run smoothly. The torsional moment of the suspension spring is related to whether the steering wheel is flexible and whether the steering wheel has a tendency to deflect when it is not stressed. There is currently no equipment for testing suspension spring torsional moments. Contents of the invention [0003] The object of the present in...
