Embodiment Construction

[0026] figure 1 The operating principle of a steer-by-wire system is shown, wherein, in a steering wheel arrangement 1 (also referred to as a steering column), the rotation of a steering wheel 2 is controlled by means of a rotary encoder 3 and electrical signals are generated therefrom. A prerequisite for this rotation is the steering torque exerted by the driver together with the steering wheel angle.

[0027] The rotary encoder 3 is arranged in the housing of a manual torque regulator (Handmomentensteller) 33, which is also called a feedback brake. The manual torque regulator 33 includes an electric motor, which is operatively connected to the steering arm and serves for the driver to transmit a steering torque via the steering wheel 2 , which corresponds to the driving feel of conventional steering. The steering torque is, for example, a moment of inertia, a return torque or a reaction torque caused by roadway influences and steering kinematics. Making it difficult for a ...

Abstract

The invention relates to a wheel steering assembly (9) having a single steerable vehicle wheel (10) which is pivotably and resiliently mounted on a vehicle chassis about a steering shaft (11), and a steering motor device (6) having a steering motor (7), with which the vehicle wheel (10 ) can be pivoted about the steering shaft (11) at a pivot angle (12, 13, 14) preset by electrical control signals, terms of a compact and simple design is improved by the fact that an inner side (19) facing the vehicle chassis, of the vehicle wheel (10) is provided with a vehicle wheel pivoting lever (22) which can allow the vehicle wheel to rotate around the steering shaft (11); the steering motor device (6) is fixed to the vehicle chassis against the inner side (19) of the vehicle wheel (10) and has a motor pivoting lever (20) which is rotatable about a rotation shaft (21) parallel to the steering shaft (11) by means of the steering motor (7);and the pivotable end region (23) of the motor pivoting lever (20) and the pivotable end region (24) of the vehicle wheel pivoting lever (22) are connected to one another by means of an articulated coupling rod (25), so that a pivoting movement of the motor pivoting lever (20) caused by the steering motor (7) causes a pivoting of the wheel pivoting lever (22).

Description

technical field [0001] The invention relates to a wheel steering assembly of a motor vehicle for deflecting a single steerable wheel, which is arranged rotatably about a steering axis on the chassis of the vehicle, wherein the wheel steering assembly comprises a steering wheel with a steering motor A steering device, by means of which the wheels can be turned around the steering axis by a rotation angle preset by means of an electrical control signal. Background technique [0002] In so-called steer-by-wire systems, steering errors given by the driver to the steering wheel are detected by means of sensors and then passed on to the control unit (ECU), which generates control from the steering torque and steering angle Signals by means of which the position of the individual rotatable wheels is controlled by the engine and thus the steerable wheels are deflected according to the driver's wishes. In such steering systems, the steerable wheels can be pivoted independently of on...
