Document Type and Number:
Japanese Patent JPH10501323
Kind Code:
A
Abstract:
A steel inner tube and thermoplastic outer tube are placed in an injection mold apparatus and a thermoplastic intermediate tube is molded between the inner and outer tubes. The intermediate tube shrink fit locks to the inner tube and shrinks relative to the outer tube to provide a selected journal-bearing torque relation therebetween. Projections and mating recesses on the inner tube and intermediate tube facilitate locking the intermediate tube to the inner tube without adhesives or other bonding agents. One or more thrust rings and recesses are formed on the mating surfaces of the outer tube and intermediate tube to preclude axial relative displacement therebetween in response to axial thrust loads. An elastomeric tubular member (or other known bushing construction) is secured over the outer tube and an outer steel tube is over the elastomeric member to provide an enhanced control arm bushing with a predetermined torque response for automotive suspension systems.
