Patent number: 6926128Abstract: A shock absorber damper assembly is provided that includes a working cylinder filled with fluid. A piston and rod are disposed in the working cylinder and move along an axis to provide dampening during a compression stroke. For a twin tube arrangement, a reservoir surrounds the working cylinder and may include a gas cell to accommodate the volume of the rod. A recoil valve controls flow of the fluid from the working cylinder to the reservoir during a recoil stroke. The recoil valve has an opening force controlling damping during the recoil stroke. A fluid passageway, which may be located in the reservoir, connects the working cylinder and the recoil valve. A check valve is disposed in the fluid passageway and opens to receive the fluid during the compression stroke. The check valve closes during the recoil stroke to retain the fluid against the recoil valve at a pressure and adjust the opening force of the recoil valve.Type: GrantFiled: June 10, 2003Date of Patent: August 9, 2005Assignee: Arvin Technologies, Inc.Inventors: James M.

Patent number: 6923299Abstract: A variable spring member includes a containment housing defining an inner chamber with alternating layers of compressible medium and electro-reactive medium. Adjacent each layer of electro-reactive medium is a coil assembly controlled by a controller. A sealed plate disposed between alternating layers of compressible medium and electro-reactive medium disperses a load exerted on the variable spring member assembly and prevents intermixing of compressible medium with the electro-reactive medium. Actuation of the coil assembly changes physical characteristics and compressibility of the layer of electro-reactive medium to vary spring rate and stiffness.Type: GrantFiled: June 23, 2003Date of Patent: August 2, 2005Assignee: ArvinMeritor Technology, LLCInventors: James M.

Publication number: 20040169324Abstract: A suspension assembly is provided that includes a strut connected between a lower control arm and a portion of the vehicle frame or body. This strut includes a hydraulic cylinder and rod disposed therein. A first spring seat is arranged on the hydraulic cylinder, and a second spring seat is arranged on the rod spaced from the other spring seat. A spring is arranged between the spring seats to provide a desired suspension load characteristic. At least one of the spring seats extends circumferentially about its connection to either the rod or hydraulic cylinder less than 360°. Since the spring engages the spring seat less than 360°, a non-uniform force is produced that generates a moment in a direction opposite the moment created by the suspension geometry. In this manner, the friction force at the bearing surface is minimized or eliminated.Type: ApplicationFiled: February 28, 2003Publication date: September 2, 2004Inventors: Marlon V.

Publication number: 20040169323Abstract: A MacPherson strut assembly is provided that has a hydraulic cylinder with a fluid chamber. A piston is arranged in the chamber, and a rod extends from the piston. A lower spring seat is supported on the hydraulic cylinder, and an upper spring seat is supported on the rod. A coil spring is arranged between the spring seats to produce a desired spring loading. In one embodiment, a compliant isolator having a sloped profile is arranged on the lower spring seat to produce an uneven spring loading. In another embodiment, a spring seat isolator may include materials of a different stiffness to produce uneven spring loading. An isolator may also be used between coils of the spring so that the compression on one side of the spring is limited more that the opposite side to produce uneven loading.Type: ApplicationFiled: February 28, 2003Publication date: September 2, 2004Inventors: Marlon V.

Publication number: 20040159515Abstract: A coil spring over shock absorber assembly includes a dampening mechanism for varying a dampening rate. The coil spring mounted to the outside of the shock absorber includes an adjustable support to change spring preload in order to adjust for vehicle load and maintain vehicle ride height. A load sensor is positioned on one of the coil spring supports and communicates changes in the coil spring preload to a controller. The controller in turn adjusts a dampening mechanism disposed within the shock absorber to optimize the dampening rate of the shock absorber relative to the coil spring preload.Type: ApplicationFiled: February 19, 2003Publication date: August 19, 2004Inventors: Stephen H.

Publication number: 20030159486Abstract: A coil spring forming system includes a mandrel having at least a portion that is selectively expandable so that a central portion of a resulting coil spring has a larger dimension than reduced diameter end sections of the spring. In one example, a plurality of coil shaping surfaces are supported relative to a central portion of the mandrel using a plurality of linkages. The coil shaping surfaces are moved using an actuator (i.e., hydraulic or pneumatic) between expanded and contracted positions to selectively vary the largest outside dimension of the mandrel. In one example, the coil shaping surfaces are spaced apart from each other in the expanded position. In another example, the coil shaping surfaces are arranged such that the mandrel has a generally continuous outer periphery when the surfaces are in the expanded position.Type: ApplicationFiled: February 25, 2002Publication date: August 28, 2003Inventors: Joseph A.

Publication number: 20030159485Abstract: A coil spring forming system allows for forming reduced diameter ends at both ends of a coil spring in a single forming process. A rotating member supports one end of the coil spring and preferably includes a die portion that establishes a configuration of that end of the coil spring. A pitch controlling device guides the coil stock longitudinally along the axis of the spring as the rotating member rotates to establish the desired pitch of the coil spring. A moving mandrel member is guided along an axis of the coil spring so that the mandrel member and the pitch controlling member establish the desired diameter of the spring at the corresponding portion of the spring. The mandrel member preferably has a forming surface with a varying outside dimension so that, depending on the placement of the mandrel relative to the coil stock and the pitch controlling member, the diameter of the resulting coil spring can be varied along the length of the spring.Type: ApplicationFiled: February 25, 2002Publication date: August 28, 2003Inventors: Joseph A.
