Problems solved by technology

The solution known from the prior art has the disadvantage that several units must be provided on the axle suspension system in order to ensure several functions
Disadvantageous consequences: high weight, large space requirement and high probability of damage and shortened service life due to the large overall contact surface with swirled foreign bodies in the chassis area

Embodiment Construction

[0028] figure 1 A preferred embodiment of the steering device according to the invention is shown in which the actuating unit 4 is indirectly fixed via a fixing element 45 to a rigid axle 10 of a commercial vehicle. The securing element 45 in particular prevents a displacement of the actuating unit 4 along the transverse axis Q relative to the frame of reference 1 . The actuating unit 4 has a reset part 41 , an active part 42 and a damping part 43 , wherein, in the preferred embodiment shown, the active part 42 and the damping part 43 are designed in one piece. Or preferably, the damping component 43 can be designed to be spaced and functionally separated from the active component 42 . Preferably, the tie rod unit 2 passes through the actuation unit 4 , wherein the tie rod unit 2 is preferably guided through the actuation unit 4 . Preferably, at the distal end of the tie rod unit 2 the tie rod unit 2 directly or indirectly engages the second pivot point 82 and is respectivel...

Abstract

The present invention relates to a steering arrangement, a restoring part (41) and a steering system, particularly for commercial vehicles and trailers thereof, comprising a tie bar unit (2), an actuating unit (4) and a lever element (6), the lever element being fixed in a pivotable manner at a first turning point (81) immovably disposed in a reference system, wherein the actuating unit (4) has a restoring part (41), an active part (42) and a damping part (43) and is secured against displacement along a transverse axis relative to the reference system, at least one of the parts (41, 42, 43) exerting a force on the tie rod unit (2) to displace the tie rod unit along the transverse axis or to secure it against displacement, wherein the tie rod unit (2) is pivotably fixed at a second turning point (82) on the lever element (6) and therefore displacement of the tie rod unit along the transverse axis leads to a pivoting movement of the lever element (6) about the first turning point (81).

Description

technical field [0001] The invention relates to a steering device, a reset element and a steering system, in particular for commercial vehicles or utility vehicles. Background technique [0002] Steering devices, in particular for commercial vehicles and their trailers, are well known in the prior art. Here, for example, by means of a tie rod perpendicular to the longitudinal axis of the vehicle, a device on which the wheels of a commercial vehicle can be mounted and which can be mounted relative to the vehicle rack pivots. Furthermore, it is known in the prior art to provide stabilizing units which dampen the vibrations of the steering device and return the steering device to a neutral position in which the commercial vehicle moves straight ahead or The wheels rotate about an axis perpendicular to the longitudinal axis of the vehicle. It is also known to supplement the force exerted by the aforementioned tie rods by an additionally arranged hydraulic or pneumatic actuati...
