  • Rotatable bushing
    Patent number: 10422372
    Abstract: A rotatable bushing for use in automotive suspension, steering, and other suitable joints is provided. The rotatable bushing includes a housing, an elastomeric portion engaging the outer surface of the housing, and a sleeve positioned within the housing. The sleeve is configured to rotate with respect to the housing and generally includes a central bore for receiving a rod or fastener therethrough. The elastomeric portion is configured to deform such that the sleeve is moveable in at least one of an axial direction and a radial direction with respect to an outer surface of the elastomeric portion.

  • Electronic damper control
    Patent number: 10774897
    Abstract: Generally described, aspects of the disclosed subject matter are directed to electronically controlled dampers having shimmed pistons. In accordance with aspects of the present disclosure, the dampers generally include a shaft having a piston with compression and rebound valves extending therethrough. For further damper tuning and adjustment, a fluid bypass assembly permits damping fluid to bypass the piston during operation. The fluid bypass assembly may include a metering pin for manual adjustment of the fluid bypass, and a control valve for electronic adjustment of the fluid bypass. In this regard, the control valve may be controlled automatically, manually, or a combination thereof.

  • Through-shaft steering damper
    Patent number: 10337583
    Abstract: Generally described, aspects of the disclosed subject matter are directed to through-shaft dampers. In accordance with aspects of the present disclosure, the through-shaft dampers generally include a shaft having a piston traveling within a body, a first chamber for a damping fluid, and a second chamber for a gas. The chambers are separated by a movable wall associated with an insert and configured to provide a volumetric change of the second chamber that is inverse to a volumetric change of the damping fluid. The insert is configured such that the sealing surfaces of the movable wall do not interface the shaft during use of the damper. In this regard, a significant reduction in the total displacement traveled by the seals is realized.

  • Digressive valve for a damper
    Patent number: 10344820
    Abstract: Generally described, aspects of the disclosed subject matter are directed to dampers having shimmed pistons. In accordance with aspects of the present disclosure, the dampers generally include a shaft having a piston with compression and rebound valves extending therethrough. The piston interfaces a shim assembly at the valve outlets such that damping fluid flow is controlled through a set of valves in one direction, and the damping fluid flow is limited through the same set of valves in the opposite direction. In this regard, the shim assembly is configured to deflect away from the piston as a result of damping fluid flow through the first valve. The shim assembly generally includes a ring shim that interfaces a shim stack to provide a configurable preload for the deflectable shims.

  • Digressive valve for a damper
    Patent number: 11002334
    Abstract: Generally described, dampers having shimmed pistons are configured for use with vehicle suspensions. The dampers generally include a shaft having a piston with compression and rebound valves extending therethrough. The piston interfaces a shim assembly at the valve outlets such that damping fluid flow is controlled through a set of valves in one direction, and the damping fluid flow is limited through the same set of valves in the opposite direction. In this regard, the shim assembly is configured to provide bleed relief of the hydraulic damping fluid at lower shaft speeds and deflect away from the piston higher shaft speeds. The shim assembly generally includes a ring shim that interfaces a shim stack to provide a configurable preload for the deflectable shims and a flow path for the hydraulic damping fluid during bleed relief.
