  • Publication number: 20070235914
    Abstract: A rubber part having a metal fitting in which the metal fitting and the rubber part are integrated through an anti-corrosion chemical film formed on a surface of the metal fitting. The anti-corrosion chemical film is a zirconium-based chemical film that is harmless to human body and environment, and is transformable following the squeeze of the metal fitting. The rubber part having a metal fitting is produced by the steps of: degreasing an outer peripheral surface of the metal fitting, subjecting the surface to shot blasting treatment, degreasing the treated surface, and water washing the treated surface; forming a zirconium-based chemical film on the treated surface; water washing and drying an outer peripheral surface of the zirconium-based chemical film; forming an adhesive layer on the outer peripheral surface of the zirconium-based chemical film; and integrating the rubber part on the outer peripheral surface of the adhesive layer.

  • Patent number: 7249756
    Abstract: The invention disclosed is a low-profile, multi-axis, highly passively damped, vibration isolation mount which when used in multiplicity provides a complete vibration load isolation mounting system. The device provides in unique fashion a very low profile interface in combination with independently determinable compliance in all directions of vibration loading. Substantial passive damping is afforded without sacrifice to strength and linearity of behavior through adaptation of a shear wall type constrained layer damping. The result is a highly passively damped vibration isolation device that provides a very low profile interface, wide ranging longitudinal and lateral compliance management, in a durable, reliable, lightweight, and compact form.

  • Patent number: 7114712
    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.

  • Patent number: 6796568
    Abstract: A suspension system for mounting a pair of wheels to a wheelchair is disclosed. The system includes a crossbar pivotally mounted to the wheelchair so as to pivot about a longitudinal axis. At least one spring assembly is located between the crossbar and the wheelchair frame for controlling the pivoting of the crossbar. A hinge assembly is mounted on each lateral end of the crossbar. The hinge assembly includes a first hinge component attached to the crossbar so as to be rotatable about a vertical axis, and a second hinge component resiliently connected to the first hinge component. The resilient connection biases the second hinge connection against rotation with respect to the first hinge component. A wheel and yoke assembly are mounted to the second hinge component.

  • Publication number: 20040113337
    Abstract: An elastomeric bushing for vehicular and non-vehicular applications includes a generally cylindrical body having spaced apart end faces, an axial passageway extending through the body and the end faces, and at least one elongate void formed in a body side and located radially outward from the axial passageway. The void includes opposite lobe end portions, each configured having an elongate major axis and a shorter minor axis. The major axes of the lobe portions are canted in opposite directions away from an imaginary vertical plane therebetween. The void further includes a connective portion between the lobe portions, the connective portion having a concave shape in a radially inward direction that defines a radially outward protruding boss. The shape and location of the lobe portions and the boss protrusion are variable to provide combined optimization of the bushing performance among spring rates, articulation durability, and load capacity.
