Tab sections, ring sections, and a convex stability ridge extend from the bushing and firmly lock the bushing to both the retention bracket and the sway bar while maintaining ease of assembly, minimizing debris buildup, resisting thermal degradation. The ring sections serve an additional sacrificial function and maintain surface contact with the sway bar beyond the limits of the retention bracket.Type: GrantFiled: April 18, 2003Date of Patent: December 6, 2005Assignee: Research and Manufacturing Corporation of AmericaInventor: Jerry Joseph

Patent number: 6843352Abstract: A shear mount assembly and a compression mount assembly are combined to control ride harshness of a shock absorber. The shock absorber includes a body and a shock rod having a hydraulically sealed portion within the body and a distally extending free portion. A mount assembly is connected at the free portion having both a compression mount and a shear mount therein. The shear mount absorbs low-input vertical loads transferred from the shock rod, and the compression mount limits vertical displacement of the shear mount and absorbs a medium-input vertical load. The shear mount and the compression mount are tuned by selecting the durometer, dimensions, and physical configuration of each mount.Type: GrantFiled: May 22, 2003Date of Patent: January 18, 2005Assignees: DaimlerChrysler Corporation, Trelleborg CorporationInventors: Mark F Jacoby, Kelly J Reynolds, James M Stevens, Timothy S O'Bryan, Phillip C Boss

Publication number: 20040145098Abstract: An energy absorber for use in a fall arrest system is disclosed and comprises a housing, a plunger and a compressible cushion. The housing has a tubular body and an end wall. The body defines a longitudinal axis. The end wall is secured to the body and has defined therethrough an aperture. The plunger includes a head disposed within said body and a rod extending from said head, through the aperture in the end wall, to a terminal end. The plunger is disposed at a rest position, whereat the head is relatively distal to the end wall, and is mounted to the housing for longitudinal movement between the rest position and an extended position, whereat the head is relatively proximal to the end wall. The cushion is disposed within the body between the end wall and the plunger head, for compression by the plunger upon said longitudinal movement thereof.Type: ApplicationFiled: August 29, 2003Publication date: July 29, 2004Inventor: Ken Thaler

Publication number: 20040113335Abstract: An improved airspring assembly includes a collapsible support member disposed within the pressurizable chamber of an airspring having a flexible sidewall. The support member is configured such that it extends and collapses along a longitudinal axis of the chamber responsive to pressurization and depressurization of the chamber, respectively. The support member also is configured such that it retains a substantially rigid outer perimeter, thereby restricting movement of the chamber's flexible sidewall toward the longitudinal axis when the chamber is depressurized. The support member also is configured such that it does not interfere with the full stroke of the airspring.Type: ApplicationFiled: December 12, 2002Publication date: June 17, 2004Applicant: The Modern Group LimitedInventor: Orain Tubbs

Publication number: 20040094879Abstract: The invention relates to a spring suspension system comprising a helical spring, a sheath, and at least one centering and bearing cup, said spring having an end turn with at least a fraction thereof being covered by said sheath, and which is centered on and bears against said centering and bearing cup. The sheath presents an opening extending around the inner periphery of the sheath and facing towards the spring axis. The fraction of the end turn covered by the sheath is centered on and bears against the centering and bearing cup via spacer means between said sheath and said centering and bearing cup.Type: ApplicationFiled: June 13, 2003Publication date: May 20, 2004Inventors: Philippe Duval, Roger Henri

Patent number: 6736381Abstract: A suspension stop device, for a motor vehicle driving wheels, including a filtering block, having an upper housing fixed relative to the vehicle body and co-operating with a lower housing mobile in rotation about a shock absorber rod and supporting a suspension spring, and a ball bearing. The upper and lower housings are made of thermoplastic material and have opposite surfaces hollowed out in a circle, about the rotation axis of the shock absorber rod, to receive a raceway for the ball bearing. The upper housing further incorporates an impact stop molded around the leading stop of the shock absorbing device, and the thermoplastic structure of the upper housing is reinforced by a ring made of overmolded elastomer.Type: GrantFiled: December 2, 2002Date of Patent: May 18, 2004Assignee: SNR RoulementsInventor: Jean Chesne

Patent number: 6698780Abstract: A computer controlled suspension system is provided for a bicycle, which can effectively absorb shock and provide stability on rough surfaces regardless of the speed of the vehicle. The suspension system has a control unit, a front suspension, a rear suspension, a front wheel terrain sensor, and a rear controller. The rear suspension is selectively adjustable by the control unit to change stiffness of the rear suspension. When the front suspension hits a bump or a depression in the surface of the ground, a signal is sent to the rear controller so that the rear suspension can react appropriately. In one embodiment, a pedaling torque sensor is operatively coupled to the control unit to input a signal that is indicative of pedaling force, and the rear controller adjusts stiffness of the rear suspension in response to the pedaling force via the control unit.Type: GrantFiled: February 27, 2003Date of Patent: March 2, 2004Assignee: Shimano Inc.Inventor: Hiroyuki Miyoshi

Patent number: 6666311Abstract: A spring strut support bearing, has a top bearing that can be affixed by its inner ring to the front end of an automobile, e.g. to the end of a piston rod of a shock absorber facing a vehicle body. The inner ring is surrounded by an outer ring with radial clearance; at least one elastic spring element made of rubber-elastic material is arranged in a gap formed by the clearance. The outer ring is disposed in a stationary manner with respect to the vehicle body; and only the component of the loading force of the shock absorber extending through the elastic spring element of the top bearing reaches the vehicle body. The inner ring has on each of its two end faces at least one elastically flexible stop buffer for limiting extreme deflection movements in moving direction of the shock absorber, the stop buffers each having the capability of being brought into contact with counter stop faces.Type: GrantFiled: July 28, 2000Date of Patent: December 23, 2003Assignee: Firma Carl FreudenbergInventor: Michael Schütz
