摘要： The invention relates to a transmission, preferably a superimposed transmission for a superimposed steering system, in which a steering angle inputted by the driver can be superimposed by another angle if necessary. Said transmission comprises at least two toothed wheels. At least one first toothed wheel provided in the transmission is designed in such a way as to keep noise levels low, and carries out the transmission of force in the event of normal functioning of the transmission, and at least one second toothed wheel in the transmission is designed in such a way as to carry out the transmission of force in the event of an overload in the functioning of the transmission.

摘要： The invention relates to a device for measuring the steering rack path of a motor vehicle steering system, which has a steering actuation device and a steering rack actively connected thereto. Said steering rack can be displaced in an essentially linear manner and pivots the wheels into a desired position via additional elements such as a steering tie rod and a steering knuckle arm. One or more field-producing means are provided in the vicinity of the steering rack, the material thereof consists of a plastic-bonded permanent-magnetic material, and has/have a course of the magnetic field line and/or course of the magnetic field intensity according to the Nonius principle. In addition, at least one sensor module is mounted in a fixed manner next to the steering rack, has at least one magnetic field sensor and at least one sensor switching circuit, and transforms the course of the magnetic field line or course of the magnetic field intensity into output signals, which can be processed further and which indicate a linear path change or the position of the steering rack in the direction of its longitudinal axis.

摘要： The aim of the invention is to integrate a steering device for adjusting a steer angle of a motor vehicle wheel, particularly a rear wheel, into a conventional wheel suspension. Said aim is achieved by a steering device comprising at least one wheel guiding member via which a wheel support is connected to a vehicle body. The wheel support is pivotable about an axis of rotation that extends substantially parallel to the wheel plane while the wheel guiding member is hingedly connected to wheel support at a distance from the axis of rotation. The length of the wheel guiding member is adjustable by means of a drive unit.

摘要： The invention relates to a vehicle steering system for motor vehicles, comprising a steering wheel (1), which co-operates with steerable vehicle wheels, in order to specify a driving direction, in addition to a hydraulic working cylinder (19), which comprises two cylinder chambers (21, 22). In addition, the system is provided with a hydraulic pressure source, which exerts a hydraulic pressure on a steering valve (15) that is configured as a slide valve. The steering valve controls the intensity of the hydraulic pressure that is routed to the cylinder chambers of the working cylinder, a differential pressure determining the active direction and intensity of the steering assistance. The steering valve is a slide valve and comprises a gating unit consisting of a control sleeve (41) and a control slide (42). The control sleeve (41) is provided with at least one control window, and the non-linear differential pressure depends on the free cross-sectional surface of the control window, said cross-sectional surface being modified by a displacement of the control slide. The border of the control window is configured in such a way that the free cross-sectional surface of the control window is modified in such a way that the intensity of the differential pressure has an essentially linear dependence on the displacement of the control slide.

摘要： The invention relates to a method for determination of a steering angle in a steering system, provided with a superimposed gear, operated by an actuator, by means of which a total steering angle on a steering gear output side part of the steering column at the gear output side, composed of a steering gear input side adjusted steering wheel angle and an additional steering angle as controlled by the actuator may be adjusted, whereby with the steering system switched off the actuator motor is locked and the steering wheel angle is determined by a steering wheel angle transducer arranged on the input side of the steering gear. According to the invention, the method is characterised in that the total steering angle (δT) is determined by an incrementally-measuring steering angle transducer (132), arranged on the gear output side on the steering column, starting from an initial value, whereby the initial value on switching on the system is determined from a value for the steering wheel angle (δH,O) recorded and stored essentially simultaneously with a previous switching off of the steering system and the total steering angle (δT,0) and the steering wheel angle (δH) determined essentially simultaneously with a switching on of the steering system by means of the steering wheel angle transducer (130).

摘要： The invention relates to a transmission lock for a superposition steering system of a motor vehicle for locking a rotatable transmission element associated with the transmission or interacting with the transmission with respect to its rotational movement. The invention is characterized in that a clamping element, especially a clamping roller (7), is used to positively lock, via a contour of an inner peripheral surface (inner contour) of an outer ring (2) and a contour of an outer peripheral surface (outer contour) of an inner ring (4), the inner ring with the outer ring against an elastic force. The clamping roller is retained in an activation cage (5) that can be locked via an actuated locking member.
