ABSTRACT:
A four way tilt mechanism maintaining the superstructure of an off-road vehicle generally horizontal while the vehicle is working on uneven terrain is disclosed. The tilt mechanism is very robust and provides independent adjustment of the angle of tilt relative to each of two pivot axes. The tilt mechanism incorporates a spherical bearing mounted on a shaft perpendicular to the longitudinal pivot axis of the tilt mechanism to eliminate end-play in the joint which forms the longitudinal pivot axis. The longitudinal and transverse pivot axes lie in the same plane so that many of the the forces which are transferred from the superstructure of the vehicle through the tilt mechanism to the chassis of the vehicle cannot cause a torque on the components of the tilt mechanism.
