Abstract:
A stabilizer bar assembly has a stabilizer bar and a pair of bushing assemblies. Each bushing assembly has an elastomeric bushing disposed around the stabilizer bar and an outer metal member disposed around the elastomeric bushing. The outer metal member compresses the elastomeric bushing between the stabilizer bar and the outer metal member to a prespecified percent of compression. When the stabilizer bar rotates with respect to the outer metal member, the compression of the elastomeric bushing stops movement between the elastomeric bushing and the stabilizer bar and between the elastomeric bushing and the outer metal member. A fastening strap is attached to the outer metal member to attach the stabilizer bar assembly to a vehicle.

Abstract:
A stabilizer bar assembly has a stabilizer bar and a pair of bushing assemblies. Each bushing assembly has an elastomeric bushing disposed around the stabilizer bar and an outer metal member disposed around the elastomeric bushing. The elastomeric bushing has a molded in rate plate to increase the stiffness of the elastomeric bushing. The outer metal member compresses the elastomeric bushing between the stabilizer bar and the outer metal member to a prespecified percent of compression. When the stabilizer bar rotates with respect to the outer metal member, the compression of the elastomeric bushing stops movement between the elastomeric bushing and the stabilizer bar and between the elastomeric bushing and the outer metal member. A fastening strap is attached to the outer metal member to attach the stabilizer bar assembly to a vehicle.
An elastomeric bushing has an outer structural member within which is located an outer elastomeric member, a self-lubricating elastomer and an inner structural member. The self-lubricating elastomer is located between the inner structural member and the outer structural member and is overmolded with the outer elastomeric member to provide adhesion between the self-lubricating elastomer and the outer elastomeric member. The self-lubricating elastomer can be located between the outer structural member and the outer elastomeric member or between the inner structural member and the outer elastomeric member.
A bushing assembly for use with an associated torque rod comprises a bar pin, an elastomeric bushing, and an outer sleeve. The bar pin has a middle section which is generally rounded but which features a flat portion between 30% and 40% of the axial length of the middle section. The elastomeric bushing bonded to the bar pin is compressively received within the outer sleeve so that the total height is reduced by approximately 10%. The edges of the outer sleeve are curled inwardly toward a longitudinal axis of the assembly.
