Abstract
A suspension assembly includes at least one leaf spring with first and second spring ends that are adapted for mounting to forward and rearward vehicle frame portions, respectively. A center portion of the leaf spring is clamped to an axle beam with a clamp. The suspension assembly includes a brake torque reactor that has one end mounted to the center portion of the leaf spring at the axle beam and an opposite end that cooperates with only one of the first and second spring ends to provide resistance for the leaf spring from deforming due to wind up generated during braking applications.
Claims20
A vehicle suspension assembly comprising:
- at least one leaf spring having a first spring end adapted for mounting to a forward vehicle frame portion, a second spring end adapted for mounting to a rearward vehicle frame portion, and a center portion adapted for mounting to an axle beam;
- and
- a brake torque reactor having a first reactor end mounted to said center portion of said at least one leaf spring and a second reactor end cooperating with only one of said first and said second spring ends to resist said at least one leaf spring from deforming due to wind up generated during braking applications, and wherein said second reactor end is uncoupled relative to said one of said first and said second spring ends such that said second reactor end is freely movable relative to said one of said first and second spring ends.
A vehicle suspension assembly comprising:
- at least one leaf spring having a first spring end adapted for mounting to a forward vehicle frame portion, a second spring adapted for mounting to a rearward vehicle frame portion, and a center portion adapted for mounting to an axle beam;
- and
- a brake torque reactor having a first reactor end mounted to said center portion of said at least one leaf spring and a second reactor end cooperating with only one of said first and said second spring ends to resist said at least one leaf spring from deforming due to wind up generated during braking applications, wherein the axle beam defines a lateral axis extending along a length of the axle beam, and wherein said brake torque reactor provides resistance for said at least one leaf spring from wrapping around the lateral axis with the axle beam during braking applications, and wherein said center portion of said at least one leaf spring is clamped vertically between an upper surface of the axle beam and a lower surface of said first reactor end of said brake torque reactor.
