ABSTRACT:
A power assisted vehicle steering system, gear or a power assistance means for a vehicle steering gear comprises a housing 1 for a rack bar 4 which is displaceable in response to a steering input. The rack bar housing is resiliently mounted in a bracket 10 bolted to a frame 9 of the vehicle and is longitudinally displaceable relative to the bracket 10 as a reaction from displacement of the rack bar 4. Longitudinal displacement of the housing 3 adjusts a spool valve 20 on the bracket 10. Adjustment of the valve 20 controls a ram 13 which reacts between the bracket 10 and the rack bar 4 to provide power assistance to the intended displacement of the rack bar 4.
The valve 20 can be incorporated as part of the ram 13. The ram 13 can be replaced by an alternative servo motor such as an electric motor and an alternative form of control such as an electrical switch to load cell can be provided for the valve 20.
Components of the gear are conveniently provided as a kit for conversion of a wholly manual gear to a power assisted gear.
