Abstract

본 발명은 자동차의 회전부나 접동부의 부품과 부품 사이에 결합되어 하중에 의한 비틀림이나 마모를 방지하며 부품의 교환성을 향상시키기 위해 러버(Rubber)재질 또는 황동등의 연질재로 이루어지는 부싱(Bushing)의 내구성을 시험하는 장치에 관한 것으로 운행되는 도로의 조건에 따라 설정된 소정시간 및 소정의 횟수동안 부싱에 미치는 자동차의 하중에 비틀림이나 마모율에 대한 내구성을 시험할시 설정된 조건에 대한 시험이 완료되기 이전에 피 측정 시험재료인 부싱의 마모율이나 비틀림의 정도가 불량으로 검출될시 내구성 시험에 대한 정보를 검출하여 표시수단에 디스플레이하며 시험장치의 동작을 자동으로 중지시켜 과 부하 발생을 방지하도록 함으로서 부싱의 내구성 시험에 신뢰성을 제공한다.The present invention is a bushing made of a soft material such as a rubber (rubber) or brass to improve the exchangeability of the parts to prevent the twist or wear due to the load is coupled between the parts and parts of the rotating or sliding parts of the vehicle Is a device for testing the durability of the vehicle.The test for the set conditions is completed when testing the durability of torsion or wear rate on the load of the car on the bushing for a predetermined time and a predetermined number of times set according to the conditions of the road being driven. If the wear rate or the degree of torsion of the bushing, which is the test material previously measured, is detected as defective, the information on the durability test is detected and displayed on the display means, and the operation of the test apparatus is automatically stopped to prevent the occurrence of overload. It provides reliability in the durability test.
