SUSPENSION SYSTEM FOR A BOGIE VEHICLE

摘要

A vehicle with an improved suspension system having a chassis with a bogie on each side of the chassis. The vehicle has a hydraulic system that includes actuator means connected between each bogie and the chassis for maintaining the chassis generally level on level ground. The hydraulic system includes first and second connecting systems extending between the two actuator means in a manner to have movement of one wheel in one bogie in one direction tend to cause movement of the corresponding wheel in the other bogie in the opposite vertical direction to the one direction to minimize tilting of the chassis. The improved suspension system also includes a second hydraulic system that can be selectively connected to one of the first and second connecting systems to tilt the chassis relative to the bogies in one direction or the other so as to generally maintain the chassis level on ground that slopes in the longitudinal direction of the vehicle.
