Abstract
A utility vehicle includes a rear suspension assembly which has a trailing arm generally extending longitudinally. Also, the rear suspension assembly includes an upper radius rod extending in a generally lateral direction relative to a centerline of the vehicle. Additionally, the rear suspension assembly includes a lower radius rod extending in a generally lateral direction relative to the centerline of the vehicle. The rear suspension assembly further includes a suspension member configured to control toe of the at least one rear ground-engaging member.
Claims26
A utility vehicle, comprising:
- a frame assembly extending longitudinally along a centerline of the vehicle;
- at least one front ground-engaging member supporting the frame assembly;
- at least one rear ground-engaging member supporting the frame assembly;
- and
- a rear suspension assembly operably coupled to the frame assembly and the at least one rear ground-engaging member, the rear suspension assembly comprising:
- a trailing arm generally extending longitudinally and operably coupled to the frame assembly and the at least one rear ground-engaging member;
- an upper radius rod extending in a generally lateral direction relative to the centerline of the vehicle and operably coupled to the trailing arm;
- a lower radius rod extending in the generally lateral direction relative to the centerline of the vehicle and operably coupled to the trailing arm;
- and
- a suspension member configured to control toe of the at least one rear ground-engaging member and generally extending longitudinally and operably coupled to the at least one rear ground-engaging member, the suspension member including a first coupling member positioned laterally adjacent the trailing arm.

A utility vehicle, comprising:
- a frame assembly extending longitudinally along a centerline of the vehicle;
- at least one front ground-engaging member supporting the frame assembly;
- at least one rear ground-engaging member supporting the frame assembly and including a knuckle, and the at least one rear ground-engaging member is configured to rotate about a rear axle;
- and
- a rear suspension assembly operably coupled to the frame assembly and the at least one rear ground-engaging member, the rear suspension assembly comprising:
- a trailing arm generally extending longitudinally and operably coupled to the frame assembly and the knuckle;
- an upper radius rod extending in a generally lateral direction relative to the centerline of the vehicle and operably coupled to the trailing arm;
- a lower radius rod extending in the generally lateral direction relative to the centerline of the vehicle and operably coupled to the trailing arm;
- and
- a suspension member operably coupled to the knuckle and positioned forward of the rear axle, the suspension member being positioned vertically intermediate upper and lower surfaces of the trailing arm, and the suspension member is configured to control toe of the at least one rear ground-engaging member, the suspension member extending generally longitudinally.
