  • Patent number: 6843472
    Abstract: An upper mounting system for a MacPherson strut includes a shock absorber mount and an air spring mount. The air spring mount is disposed coaxially around the shock absorber mount. A curved spherical interface of the air spring mount permits pivotal movement of the air spring such that it maintains a coaxial relationship with the shock absorber. The curved spherical interface also provides a seal for sealing the gas chamber of the air spring.

  • Patent number: 6755403
    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.

  • Patent number: 5413254
    Abstract: A feeder housing is suspended from a material supply bin and has lower and upper cylindrical members with the upper member isolated from the lower member by a flexible collar which also seals the cavity formed by the members. The lower member is suspended from the upper member and has a concave bottom wall with a discharge port. A first fixed baffle next adjacent the bottom wall is a ring with shape of a segment of a toroid with angularly oriented sides having a central opening. A second conical baffle is over the central opening and is axially displaced toward the first baffle between a closed state and a material flow open state wherein material flow is normally arrested until the housing and baffles are vibrated. In a second embodiment, a single fixed baffle comprises a pair of symmetrical cones secured inverted relative to each other over a feeder housing discharge and inlet port.

  • Patent number: 5397112
    Abstract: A circular cylindrical elastomeric member is formed with an annular recess and two spaced apart pockets in communication with the recess. An outer metal tube receives an inner ring in interference fit in the tube bore, the ring having at least one peripheral depression in an outer surface and a pair of spaced apertures through the ring each communicating with a different corresponding aperture forming at least one channel communicating with the pockets and apertures which are congruent with the pockets. The member is axially forced into the ring and outer tube while submerged in an imcompressible hydraulic fluid to radially compress and elongate the member during member insertion and fill the channel and pockets with the fluid. The ring seats in the member recess. An inner tube is then axial forced into the bore of the elastomeric member and locked to the member by the radial compressive forces without vulcanization or a bonding agent.
