Abstract
A V-configuration torque rod has an apex pivotal joint assembly which includes either a single forging or a pair of eyelets each of which form one arm of the V. An intermediate sleeve is located within the forging or each eyelet and an elastomeric bearing socket is located within the sleeve. The bearing socket defines a pocket within which a bar-pin journal is located. Each eyelet of the apex pivotal joint assembly is connected to a tube which is connected to an end pivotal joint assembly. Each end pivotal joint assembly has an internal joint configuration the same as the apex pivotal joint assembly.
Claims31
A pivotal joint assembly comprising:
- an eyelet member defining a bore;
- an intermediate sleeve extending through said bore, said intermediate sleeve defining an aperture;
- an elastomeric bearing socket disposed within said aperture, said elastomeric bearing socket defining a pocket;
- a thrust washer disposed adjacent said elastomeric bearing socket;
- a snap ring disposed within a groove formed in said intermediate sleeve adjacent said thrust washer;
- and
- a bar-pin journal slidingly disposed within said pocket of said elastomeric bearing socket.
A pivotal joint assembly comprising:
- an eyelet member defining a bore, said eyelet member comprising a first and a second eyelet, said second eyelet being disposed adjacent said first eyelet, said first and second eyelets defining said bore;
- an intermediate sleeve extending through said bore, said intermediate sleeve defining an aperture;
- an elastomeric bearing socket disposed within said aperture, said elastomeric bearing socket defining a pocket;
- and
- a bar-pin journal slidingly disposed within said pocket of said elastomeric bearing socket.
A torque rod comprising:
- a first end joint assembly;
- a first elongated member secured to said first end joint assembly;
- a second end joint assembly;
- a second elongated member secured to said second end joint assembly;
- an apex pivotal joint assembly secured to said first and second elongated members, said apex pivotal joint assembly comprising:
- a first eyelet defining a first bore;
- a second eyelet defining a second bore;
- an intermediate sleeve extending through said first and second bores, said intermediate sleeve defining an aperture;
- an elastomeric bearing socket disposed within said aperture, said elastomeric bearing socket defining a pocket;
- and
- a bar-pin journal slidingly disposed within said pocket of said elastomeric bearing socket.
