Problems solved by technology

[0004] The shock absorber test bench produced by famous foreign testing machine manufacturers, such as the shock absorber test bench sold by the American MTS company, is driven by a hydraulic servo cylinder, and can be used to test the shock absorber’s performance characteristics, static friction characteristics, spring static characteristics, etc. The test has a certain degree of versatility, but due to the high price, the general shock absorber manufacturer cannot purchase it, and cannot carry out the static load characteristic test of the shock absorber
For the static load characteristics of the rear shock absorber, it is necessary to apply a lateral force to the outer cylinder of the shock absorber during the test, and a special clamping mechanism needs to be installed, which causes certain difficulties for the user.

Abstract

The invention provides a testing device for static load characteristics of a shock absorber at the rear part of a motorcycle. The testing device comprises a driving device and a clamping device, wherein the driving device and the clamping device are arranged separately from top to bottom; the driving device comprises a driving mechanism, a force sensor and a thread jacket which are connected in sequence from top to bottom; a moving part of the driving mechanism is also connected with a displacement sensor; the clamping device comprises a base, an installing pin seat and a clamping seat which are connected in sequence from bottom to top; the clamping seat is a vertical structure body which has a left-inverted U-shaped cross section and consists of an upper frame, a side frame and a lower frame; the outer plane of the lower frame is provided with a convex ear-shaped pin ring; a pin hole of the pin ring are pinned with pin holes at the two sides of the installing pin seat fixed on the base by virtue of a pin shaft; the center of the upper frame is provided with a clamping round hole; the outer plane of the side frame is also vertically connected with a lever; one end with the extending length a of the lever is also vertically connected with a straight rod; the other end of the straight rod is provided with a hanging hole for hanging and connecting a heavy block. The testing device provided by the invention has the advantages that the structure is simple, the function of applying a lateral force is achieved, and the testing requirement for the static load characteristics of the shock absorber in related standard regulations is met.

Description

technical field [0001] The invention relates to product performance testing and testing technology, in particular to a method and device for testing static load characteristics of rear shock absorbers of motorcycles. Background technique [0002] As a key component in a driving vehicle, the shock absorber plays an important role in the comfort, safety and maneuverability of the driving vehicle. The purpose of the Static Load Characteristics test is to test the static resistance of the shock absorber other than the damping force. The static load characteristics include the static friction force between the relative moving parts inside the shock absorber, the resistance of the air chamber volume change and Due to the additional frictional resistance caused by the force deformation of the oblique installation (especially the front shock absorber), it is the dimensional processing accuracy, geometric shape accuracy, structural rigidity, material strength, fit accuracy, assembly ...
