摘要： A steering system for a vehicle includes a sector shaft defining a bore therein and rotatable about a central longitudinal axis. The steering system also includes a lash adjuster translatable within the bore along the central longitudinal axis. In addition, the steering system includes an end cap cover abutting the lash adjuster and spaced apart from the sector shaft to define a first cavity between the end cap cover and the sector shaft, and a housing abutting the end cap cover and spaced apart from the sector shaft to define a second cavity between the housing and the sector shaft. The steering system also includes a seal surrounding and abutting the sector shaft, wherein the seal separates the first cavity from the second cavity.

摘要： A tunable hydraulic bushing mounts a steering gear to a vehicle frame member. The bushing is filled with a fluid and includes an inertia track and a pressure valve separating first and second fluid chambers or cavities. The inertia track provides uninterrupted fluid communication between the first cavity and the second cavity. The pressure valve is movable between an open position, which allows fluid communication though the pressure valve between the first cavity and the second cavity, and a closed position, which blocks fluid communication though the pressure valve between the first cavity and the second cavity. The pressure valve may be configured to be closed during loads induced by smooth road shake and open during loads greater than smooth road shake.

摘要： A steering system includes a wheel rotatable between on-center and off-center positions, and a shaft having teeth. The shaft defines a cavity and is rotatable about an axis that is perpendicular to the teeth. The system includes a nut having cogs defining grooves therebetween, wherein each tooth is matable with a groove. The system includes a lash adjuster translatable within the cavity, and a retainer contacting the adjuster and shaft, and configured for positioning the shaft along the axis as the wheel rotates. A center one of the gear teeth meshes with one of the grooves to define a first gap having a first thickness therebetween when the wheel is in the on-center position. An outer one of the gear teeth meshes with an outer groove to define a second gap having a second thickness that is greater than the first thickness when the wheel is in the off-center position.
