摘要： A steering booster system for a motor vehicle has an electronic control unit which senses by way of force or torque sensors the amount and direction of forces and torques applied to a manual steering wheel and correspondingly controls, via a transmission arrangement, the steering-force-assisting connection of an electric motor into a steering gear line coupling the manual steering wheel and the steered vehicle wheels. The manufacture of the system is simplified and the controllability of the force transmission between the electric motor and the steering gear line is improved by providing that the transmission arrangement has an electrically switchable clutch for each steering direction, i.e., left or right. The two clutches are arranged such that, when the rotating direction is the same at the input of the transmission arrangement assigned to the electric motor, they in each case cause another rotating direction at the output of the transmission arrangement assigned to the steering gear line. The electronic control unit controls the amount of the steering force assistance by way of the slip of the respective clutch and/or by way of the torque of the electric motor.

摘要： The present invention concerns a servo valve, in particular for hydraulic power steering systems of motor vehicles, in the form of a rotary slide valve having a rotary slider and a control bushing which coaxially encloses the latter and is rotatable about a rotation axis, against spring force, relative to the rotary slider. The present invention includes a particular spring arrangement which has two helical compression springs lying in a radial plane of the rotation axis.

摘要： A recirculating ball gear, in particular for a steering system of a motor vehicle, comprises a nut, which is mounted in a housing by way of a bearing, wherein at least one spring element is disposed on each end face of the bearing between the bearing and the housing. During operation, the recirculating ball gear is exposed to impact in the axial direction, whereby the gear may become damaged over time and annoying rattling noise may develop in the recirculating ball gear. The spring elements are thus operated in the progressive area of characteristic curve.

摘要： A servovalve, in particular for hydraulic power-assisted steering systems of motor vehicles, is in the form of a rotary spool valve with a rotary spool and a control bush, which coaxially surrounds the rotary spool and can be rotated against spring force relative to the rotary spool. A bearing, by which the control bush and the rotary spool are secured axially relative to one another, is integrated into the rotary spool valve.

摘要： In a servo valve for hydraulic power steerings of motor vehicles which consists of a rotary spool valve having a rotary spool rotatably disposed in a control sleeve, a front end of the control sleeve and a flange structure on the rotary spool have spaced oppositely arranged faces forming a gap therebetween in which a C-shaped spring is disposed which extends around the rotary spool and has free opposite ends in engagement with pins projecting axially toward one another from the opposite faces of the control sleeve and the flange structure when both are in a center position relative to one another so as to bias the control sleeve and the flange structure into such center position with a predetermined spring force.
