Abstract

본 발명은 운행되는 자동차의 주행방향을 운전자의 선택에 따라 조정하는 파워 스티어링 기어(Power Steering Gear)의 내구성을 시험하는 장치에 관한 것으로 특히 운행되는 도로의 조건에 따라 설정된 소정시간 및 소정의 횟수 동안 파워 스티어링 기어의 동작상태에 대한 내구성을 시험할시 설정된 조건에 대한 시험이 완료되기 이전에 피 측정 및 시험재료인 파워 스티어링 기어가 정상적으로 동작되지 않거나 파손이 검출될시 내구성 시험에 대한 소요시간과 테스트 횟수를 검출하여 표시수단에 디스플레이하며 시험장치의 동작을 자동으로 중지시켜 시스템의 과부하발생을 방지하도록 함으로서 파워 스티어링 기어의 내구성 시험에 신뢰성을 제공한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for testing the durability of a power steering gear for adjusting a driving direction of a driving vehicle according to a driver's selection. When testing the durability of the operating condition of the power steering gear, the time required and the test for the durability test when the power steering gear, which is the measured and test material, is not operated normally or damage is detected before the test for the set conditions is completed. It detects the number of times and displays it on the display means and automatically stops the operation of the test apparatus to prevent overloading of the system, thereby providing reliability in the durability test of the power steering gear.

Description

Durability test device for power steering gear.
