Title: RACK STEERING MECHANISM PARTICULARLY FOR MOTOR VEHICLES
Abstract:
A rack steering mechanism enables to reduce shocks due for example to the wheel fluttering, and which could be axially exerted on the rack (3). These shocks are transmitted to the drive pinion (2) and cause pertubating turning oscillations to the steering wheel. By means of a friction device mounted above the drive pinion (2), it is possible to adjust the "no-load rotation moment" of the steering in a reliable and wear resistant way. The friction device comprises a wear ring (11) secured to the steering shaft (4) on which a pressure is exerted by a friction disk (14) actuated by a spring (13) and secured to the casing (1) by means of a threaded ring (16) so as to avoid rotations.
