Abstract
A torsional bushing system is provided and includes an elongated inner member that has disposed thereon a plurality of elastomer bushings of a generally square configuration. The assembly is inserted into a housing which is connected to a trailer, automobile or other vehicle. The end of the inner member is linked to a wheel assembly for the vehicle.
Claims20
A torsional bushing assembly for use in a vehicle, the assembly comprising:
- a housing having a generally square cross-section;
- an elongated inner member disposed within the housing and having a main portion of generally square cross-section and a generally cylindrical end portion;
- and,
- a plurality of bushings disposed between the housing and the main portion of the inner member, the bushings having a continuous generally square outer periphery with outer peripheral surfaces sealingly engaging the housing and a generally square aperture with corresponding inner surfaces defined therein sealingly engaging the main portion of the inner member, each outer peripheral surface being disposed at an angle of 45 degrees relative to a corresponding inner surface, adjacent bushings defining a sealed chamber located between the adjacent bushings.
A torsional bushing assembly for use in a vehicle. The assembly comprising:
- a housing;
- an elongated inner member disposed within the housing and having a main portion of generally square cross-section and a generally cylindrical end portion;
- a plurality of bushings disposed between the housing and the main portion of the inner member, the bushings having a generally square outer periphery with outer peripheral surfaces and a generally square aperture with corresponding inner surfaces define therein to deceive the main portion of the inner member, each outer peripheral surface being disposed at an angle of 45 degrees relative to a corresponding inner surface;
- and
- a snap bushing disposed within the housing and positioned on the end portion of the inner member.
A torsional bushing system for use in a vehicle, the system comprising:
- a housing having a generally square cross-section;
- an elongated inner member disposed within the housing and having a main portion of generally square cross-section and a generally cylindrical end portion;
- a plurality of bushings disposed between the housing and the main portion of the inner member, the bushings having a continuous generally square outer periphery with outer peripheral surfaces sealingly engaging the housing and a generally square aperture with corresponding inner surfaces defined therein sealingly engaging the main portion of the inner member, each outer peripheral surface being disposed at an angle of 45 degrees relative to a corresponding inner surface adjacent bushings defining a sealed chamber located between the adjacent bushings;
- a linkage arm connected to the end portion;
- and,
- a spindle connected to the linkage arm adapted to support a hub and tire assembly.
A torsional bushing assembly for use in a vehicle, the assembly comprising:
- a generally cylindrical housing;
- an elongated inner member disposed within said housing and having a main portion of generally cruciform cross-section and first and second ends;
- and
- a bushing disposed between the housing and the main portion of the inner member, the bushing having a continuous generally cylindrical outer peripheral surface sealingly engaging the housing and a generally cruciform shaped aperture defined therein sealingly engaging the main portion of the inner member.
