Steering Column Assembly

摘要

A steering column assembly for a vehicle, comprises a shroud comprising an axially movable upper portion and an axially fixed lower portion, which move telescopically to provide adjustment for reach of the steering column assembly, a steering shaft supported by the shroud, a pivot which connects a part of the lower portion to a fixed part of the vehicle, a clamp mechanism which releasably fixes the upper and lower portions and the shroud in position relative to a further fixed part of the vehicle. A sprung support assembly is secured to a fixed part of the vehicle and includes an axle that passes underneath the upper portion of the shroud and a cylindrical roller that surrounds a part of the axle and has an outer surface that engages the underside of the shroud and an inner surface that bears on the axle, the sprung support at least partially supports the weight of the shroud when the clamp mechanism is released, and the cylindrical roller rotating around the axle as the shroud is adjusted for reach.
