Detection device for detecting durability of vehicle shock absorber sleeve assembly

Abstract

The invention discloses a detection device for detecting the durability of a vehicle shock absorber sleeve assembly, and aims to solve the problems that the actual use condition of the sleeve assembly cannot be effectively simulated, the test time is long, and the design and development progress of a whole vehicle and a shock absorber is delayed in the prior art. The device comprises a support, a mounting plate, a first actuator, a second actuator, three bearings and a torsion bar, the mounting plate is connected with the support, the three bearings are all connected with bearing seats, the three bearing seats are all connected with the mounting plate, the torsion bar penetrates through the three bearings, a third shaft sleeve is in clearance fit with a third bearing, and the third shaft sleeve is in clearance fit with the third bearing. A torsion arm is arranged at the end, close to the first bearing, of the torsion bar, the torsion arm is connected with a second connecting piece and a second actuator, a to-be-tested part is installed at the position, between the second bearing and the third shaft sleeve, of the torsion bar, and a first connecting piece is installed on the to-be-tested part and connected with the first actuator.

Description

technical field [0001] The invention belongs to the technical field of detection tools, and in particular relates to a detection device for detecting the durability performance of a vehicle shock absorber casing assembly. Background technique [0002] The bushing assembly is one of the key performance components of the vehicle shock absorber assembly. During the design and development process of the whole vehicle and shock absorber, it is necessary to test the durability of the casing assembly to verify whether the performance attenuation rate and reliability of the casing assembly under certain working conditions meet the product design requirements. [0003] In the prior art, the working conditions for testing the durability of the casing assembly are: the reciprocating force condition at a certain angle to the axis of the casing assembly and the working condition of reciprocating torsion around the axis of the casing assembly, and two are usually used in the prior art.
