Abstract
A utility vehicle ha a rigid axle that can be pivoted about a fixed swivel extending the longitudinal direction of the vehicle. The axle is mounted on a swinging link, with which the cylinder of a hydro-pneumatic spring suspension engages. Such vehicle are equipped with a spring suspension for road travel at speeds in excess of 40 km/hr. However, both the spring action and the swivel movement of the rigid axles are potentially dangerous when working on uneven or sloping ground. This invention permits both the spring action and the swivel movement of the rigid axle to be prevented. This invention is particularly well suited for vehicles used in agriculture, forestry, and construction.

A vehicular chassis and suspension assembly comprising:
- a chassis;
- a suspension arm connected to said chassis for pivoting movement relative thereto;
- an axle connected to said suspension arm for swiveling movement relative thereto;
- an actuator connected between said chassis and said suspension arm for selectively controlling said pivoting movement of said suspension arm relative to said chassis;
- and
- a lever supported on said chassis and selectively movable between a first position, wherein said lever restricts said swiveling movement of said axle relative to said chassis, and a second position, wherein said lever does not restrict said swiveling movement of said axle relative to said chassis.
