Composite multi-axle suspension for vehicles
This patent describes a load dividing suspension system for vehicles comprising a chassis frame, a drive axle assembly supportively connected with the chassis frame, a fluid-pressure responsive spring means on the drive axle assembly and engaging the chassis frame and exerting a variable lifting force thereon. A tag axle assembly is attached to the chassis frame and includes a vertically swingable support structure for wheels of the tag axle assembly, a distribution valve means on the vehicle for pressurized fluid from an on-board supply of such fluid and having a connection with the supply, an outlet connection and a pressurized fluid line leading to and connected with the fluid-pressure responsive spring means, and an operating linkage for the valve means. The linkage is connected between a movable control element of the valve means and the vertically swingable support structure.
