ABSTRACT:
A novel wishbone system attaches single or dual axles of wheeled vehicles to a vehicle frame where such system can be used for driving or following axles and steering or non-steering axles. A solid wishbone is attached to the axle and is further attached to the vehicle frame by a fixed ball and socket arrangement. Furthermore, a telescoping wishbone ball and socket are attached to the vehicle frame by a telescoping wishbone pivot pivotably mounted to the telescoping wishbone casing. One end of the telescoping wishbone shaft moves within the telescoping wishbone casing and the other end of the telescoping wishbone shaft contains the telescoping wishbone socket. The telescoping wishbone ball is fixably attached to the solid wishbone near the axle or directly to the axle. The basic system includes upper and lower suspension supports between which are placed airbags or coil springs. The airbags are placed at the outer extremity of each suspension support. In the steering following axle mode, a turntable is used to rotate the following axles by means of a steering assembly. Furthermore, in single tire arrangements a steering mechanism steers the individual tires. In steering drive axles, the telescoping wishbone and solid wishbone are modified to provide an unobstructed path for the drive lines.
