Abstract

후륜2축을 갖는 상용차량에서 선회시 후륜제2축이 선회 외측이 선회내측보다 넓게 벌려질 수 있도록 하여 실질적으로 조향이 이루어질 수 있도록, 제1,2리프 스프링 어셈블리를 갖고 후륜제1,2축을 갖는 차량에 있어서, 상기한 제1리프 스프링의 상측에 후륜제1축을 위치시키고 상기한 제2리프 스프링은 후륜제2축의 하측에 위치시키며, 상기한 제1리프 스프링의 일측은 고정된 브라켓트에 회동가능하게 연결함과 아울러 상기한 제2리프 스프링의 후단부는 차체에 회동가능하게 설치된 새클에 연결하며, 상기한 제1,2리프 스프링은 차속에 따라 선회시 작동하는 액츄에이터에 의해 회동하는 조향부재에 각각 연결되어 이루어짐을 특징으로 하는 차량용 후륜2축 셀프 조향장치를 제공한다.In a commercial vehicle having two rear wheels, the rear wheel second axle has a first and second leaf spring assembly and a rear wheel first and second axle so that the steering outer side can be wider than the inner side of the turning so that steering can be performed substantially. In the vehicle, the rear wheel first axle is positioned above the first leaf spring, and the second leaf spring is located below the rear wheel second axle, and one side of the first leaf spring is rotatable to a fixed bracket. In addition, the rear end of the second leaf spring is connected to a sackle that is rotatably installed on the vehicle body, and the first and second leaf springs are respectively connected to a steering member that is rotated by an actuator that operates when turning in accordance with the vehicle speed. It provides a vehicle rear wheel 2-axis self-steering device characterized in that the connection is made.
