RACK AND PINION STEERING APPARATUS HAVING RACK BEARING WEAR COMPENSATION WITH DAMPING |
摘要 |
A power steering apparatus includes a housing defining a chamber. A rack is disposed within the chamber and is moveable along a longitudinal axis. A pinion extends into the chamber for meshing engagement with the rack. A bearing supports the rack relative to the housing and is moveable relative to the housing to re-position the rack relative to the pinion. An adjustment mechanism continuously biases the bearing in response to loosening of the meshing engagement to re-position the rack. A dampener resists the movement of the bearing to slow the re-positioning of the bearing. Preferably, the dampener includes a plastic fluid having a very high viscosity. The plastic fluid is disposed between adjacent moving parts to resist the relative movement between the bearing and the housing.
