Abstract
A tracked vehicle has a chassis including a tunnel. An engine is connected to the chassis. An endless drive track is disposed below the tunnel and operatively connected to the engine. A suspension assembly supports and tensions the endless drive track. The suspension assembly has a longitudinal direction and a lateral direction. The suspension assembly includes a rail engaging the endless drive track. The rail extends in the longitudinal direction. A suspension arm has an upper end pivotally connected to the chassis about a first lateral axis, and a lower end pivotally connected to the rail about a second lateral axis. At least one shock absorber is connected between the chassis and the rail for biasing the rail away from the chassis. The chassis is pivotally connected to the rail via the suspension assembly about a longitudinally extending axis. A suspension assembly is also disclosed.
