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

Patent number: 6764066Abstract: An hydraulic damping mount has an outer sleeve, an inner sleeve for securing thereto a piston of a spring strut (activatable in at least one direction), an elastomeric body and two chambers. The two chambers are interconnected via a gap. The inner sleeve comprises a radially projecting boss separating the two chambers from each other. The connection between the two chambers is configured in accordance with the invention as a gap between the boss and the outer sleeve so that when activated, the fluid flow through the gap is in the direction opposite to the movement of the boss, resulting in a reduction in the stiffness. This simplifies assembly whilst enhancing the stiffness response of the mount. The invention relates furthermore to a mount for supporting a spring strut in making use of such a mount.Type: GrantFiled: February 14, 2003Date of Patent: July 20, 2004Assignee: Trelleborg Automotive Technical Centre GmbHInventor: Arndt Graeve

Patent number: 6427814Abstract: A liquid-encapsulated damper mount includes an outer member fixed to a vehicle body, and an inner member fixed to an upper end of a damper. The outer member and the inner member are connected to each other by first, second and third elastomer members. A first liquid chamber defined between the first and second elastomer members communicates with a second liquid chamber defined between the second and third elastomer members through a restriction. The restriction is defined in mating surfaces of the inner member and a ring member which are made of a metal and hence, even if the second elastomer member is deformed in any manner, the cross-sectional area of the restriction is not changed. Thus, when a load of a very low speed is inputted from a road surface, a stable damping force can be generated in the liquid-encapsulated damper mount, thereby preventing the resonance of an unsprung portion to enhance the riding comfort during traveling of a vehicle on a flat road.Type: GrantFiled: February 16, 1999Date of Patent: August 6, 2002Assignee: Honda Giken Kogyo Kabushiki KaishaInventor: Yasuo Miyamoto

Patent number: 6298962Abstract: There is disclosed a member for use with an arm that is used as an automobile suspension arm, for example. The member comprises a rodlike body and bushing-mounting portions formed at both ends of the rodlike body. The rodlike body consists of a hollow tube fabricated by extruding an aluminum material into a circular cross section.
