Motor vehicle power steering gear |
摘要 |
A motor vehicle power steering gear having a spool shaft connected to a steering wheel, a pinion head connected to a steered wheel, a torsion bar between the spool shaft and the pinion head, a valve for regulating a hydraulic steering assist boost pressure in response to rotation of the spool shaft from an on-center position relative to the pinion head against a restoring force of the torsion bar, and a quiet preload apparatus including a C-shaped spring around the spool shaft having a pair of resilient jaws, a drive pin on the spool shaft clamped with a preload between the resilient jaws, and a cushioned abutment on the pinion head clamped with the preload between the resilient jaws. The cushioned abutment includes a pair of radial cantilever springs which flex upon engagement with corresponding ones of the resilient jaws during forced oscillation of the pinion head back and forth through the on-center relative position of the spool shaft to minimize audible noise associated with such engagements.
