In a rack-and-pinion steering gear for motor vehicles, in which in a steering gear housing a pressure piece is guided within a stub having an axis normal to that of the steering-gear housing so that the pressure piece is longitudinally displaceable in the guide stub. A preloading force acts on the pressure piece at an angle to the direction of motion of the pressure piece such that the pressure piece is held in engagement with a side wall of the stub in either direction of movement of the rack.

Steering gear for motor vehicles

A hydraulic power steering system, in which the servomotor also acts as a steering damper. Damper valves are arranged on hydraulic lines between the servomotor and servo valve. In order to compensate the temperature-dependent viscosity of the hydraulic medium, throttle elements of the damper valves cooperate with spring arrangements operating as a function of temperature (bimetallic springs, springs consisting of form memory alloy).

Hydraulic power-assisted steering

Damper valve configuration

The invention relates to a damper valve arrangement, which can be combined with a servomotor of a hydraulic power steering system to form a steering damper. For calibration purposes, the damper valve arrangement has a bypass duct with a calibratable throttling resistance.

Damper valve arrangement

In a damper valve for use in a steering damper arrangement of a motor vehicle having a hydrostatic displacement motor for operating the vehicle steering mechanism wherein hydraulic fluid lines extending between the hydraulic motor and a servo-valve include the damper valve, the damper valve has a throttling arrangement which permits fluid flow in one direction and limits fluid flow in the opposite direction but permits essentially unlimited fluid flow in both directions as long as the pressure difference across the damper valve is below a predetermined threshold value so as to permit unrestricted normal steering movements of the vehicle steering system, but dampen shock movements thereof.

Damper valve

A safety steering column for a motor vehicle comprising a multi-member steering spindle, of which a portion close to the steering wheel is guided in a steering column tube which is fastened on a cross member largely unaffected in the case of a front collision. A portion of the steering spindle located close to the steering gear is constructed as a deformation member for absorbing an axial displacement of the steering gear. The deformation member is hinged on at one end to the portion of the steering spindle close to the steering wheel and is hinged on the other end to the input shaft of a steering gear. The input shaft of the steering gear has a desired bending point which is designed such that, when the steering gear in the direction of the passenger compartment such as during an accident, first the axial displacement path of the deformation member is largely used up before a buckling deformation starts at the desired bending point. A vehicle-body-fixed supporting element, such as a catch loop, may be provided to support the buckling deformation.

Safety steering column for a motor vehicle

The invention relates to a damper valve for use on a coupler for hydraulic lines, in particular those which connect a hydraulically actuated servomotor of a servo control to a servo valve. According to the invention, all the elements having a damping effect are arranged captively in the coupler.
