Zusammenfassung: | The invention relates to a hydraulic power assisted steering system (1) for a vehicle, in particular an electrohydraulic power assisted steering system for a motor vehicle. Said hydraulic power assisted steering wheel comprises a servo valve (2) and the relative movement thereof actuates control parts thereof of a piston rod (3) of a servocylinder (4) and modifies at least one steering angle (.beta.) of a wheel (5) which co-operates with the piston rod (3). The power assisted steering system (1) also comprises an electric servomotor (6) which drives a rod (7) which is used to adjust the steering angle of the wheel (5) in the same direction as the servocylinder (4). The aim of the invention is to produce an electrohydraulic power assisted steering system (1) which is compact as possible in the region of the actuator and which can be used in a flexible manner for different vehicle classes. According to the invention, the rod (7) and the piston rod (3) of the servocylinder (4) are arranged in a parallel manner in relation to each other and interact with each other on an additional element (8) for adjusting the common steering angle of the wheel (5). |
