Abstract: A steering system for a vehicle, e.g., a power-steering system for a motor vehicle, includes a gear unit, which converts a rotational movement of a first gear element, such as a pinion, to an axial shifting movement of a rod or gear rack. The gear unit is used for adjusting the steering angle of one or more wheels of the motor vehicle. The shifting movement of the rod occurs between a first limit stop and a second limit stop and is detected by a position sensor.

Abstract: In a method for fastening a torque measurement device for detecting a relative torque between an input shaft and an output shaft of a steering system, e.g., of a rack-and-pinion power-assisted steering system, the torque measurement device is integrally formed locally into the input shaft and/or the output shaft by deformation elements.

Abstract: An electrical steering system for a vehicle comprises a steering shaft, which is mounted rotatably in an accommodating space of a steering housing, and an electric motor, which, acts upon steering shaft over a transmission. Furthermore, a coil spring housing with a coil spring is provided in the accommodating space. The accommodating space is divided by a partition into a section accommodating the coil spring and a section accommodating the transmission. A damping almond is integrated in the partition. The housing of the coil spring forms part of the partition.

Abstract: In a method for fastening a torque measurement device (4) for detecting a relative torque between an input shaft (2) and an output shaft (3) of a steering system (1), in particular of a rack-and-pinion power-assisted steering system, the torque measurement device (4) is integrally formed locally into the input shaft (2) and/or the output shaft (3) by means of deformation elements (8).

Abstract: An electrically supported power steering system for motor vehicles includes an input shaft, which is mechanically linked to a steering wheel for transmitting a steering torque required for steering of wheels to be steered. An output element is mechanically linked to the wheels to be steered. An electric motor, through which a servo force can be applied directly or indirectly to the output element, is arranged on the power steering system. The input shaft and the output element are connected to one another via a torsion bar. A detection unit for detection of a torque acting on the input shaft and of other steering-specific parameters includes a single pulse generator designed as a magnet ring and at least one magnetoresistive sensor.

Abstract: A power steering system, in particular for motor vehicles, includes a steering valve (15), for controlling a pressure medium for a servomotor, has two inlet seat valves (23, 24) and two outlet seat valves (25, 26), each with one closing body (31; 36). The closing bodies (36) of the outlet seat valves (25, 26) are actuatable via an actuating device as a function of a rotary motion of a steering-wheel shaft connected to an input member (10) of the steering system. The closing bodies (31) of the inlet seat valves (23, 24) are hydraulically pressure balanced with reference to a pressure of a pressure source, and by the force of locking springs (32) they keep the inlet seat valves (23, 24) closed in the neutral position of the steering valve. Each locking spring (32) is supported at one end on a closing body (31) of one of the inlet seat valves (23, 24) and on the other on the actuating device. The outlet seat valves (25, 26) are opened in the neutral position of the steering valve (15).
