AI Technical Summary

Technical Problem

Existing rubber suspension component durability testing equipment has low integration or complex structure, making it difficult to meet the diverse testing needs of suspension components of different specifications, and it is also difficult to accurately simulate their performance degradation law under dynamic load.

Method used

Employing a servo motor-worm gear-worm wheel transmission structure and an eccentric shaft-elliptical sliding hole transmission structure, combined with rubber clamping protrusions, the clamping plate achieves precise opening and closing and periodic pulling, simulating the dynamic stress state of the suspension component. Automated testing is achieved through servo motor drive.

Benefits of technology

It achieves reliable fixation and accurate simulation of the suspension components, ensuring the authenticity and stability of test data, reducing labor costs, and improving test efficiency.

Abstract

This invention discloses a durability testing device for automotive rubber suspension components, comprising a mounting plate on which two test mating mechanisms are mounted. Each test mating mechanism includes two clamping and fixing members, and a test driving member is provided between each pair of adjacent clamping and fixing members and the mounting plate, thereby driving and adjusting the adjacent clamping and fixing members. This invention, through the mating arrangement of its various structures, not only facilitates durability testing of automotive rubber suspension components via the test mating mechanisms, but also simplifies operation and facilitates widespread adoption.
