Embodiment Construction

[0019] figure 1 A rough schematic diagram shows a wheel suspension arrangement 10 for a motor vehicle, in which a wheel carrier 12 is articulated to the only indicated bodywork via transverse control arms 14 , 16 as wheel guide elements. 18 on.

[0020] The wheel hub bracket 12 that receives the wheel 20 in a rotatable manner is divided into a guide 22 hinged on the lateral control arms 14, 16, a carrier 24 that receives the wheel 20 through a corresponding wheel support (not shown) and Two adjusting cylinders 26 , 28 are rotatably supported on the guide part 22 and on the carrier part 24 and can be adjusted on an axis of rotation 32 extending perpendicularly to the inclined surfaces 30 facing each other. . Rotation of one or both adjusting cylinders 26 , 28 pivots carrier part 24 relative to wheel axis of rotation 34 , and correspondingly adjusts the track and / or camber of wheel 20 of wheel suspension arrangement 10 .

Abstract

The invention relates to a device for adjusting the camber and / or toe of the wheels (20) of wheel suspensions (10), especially for motor vehicles, comprising a wheel carrier (12) on which the respective wheel (20) is rotatably mounted and which is divided into a carrier part (24) receiving the wheel, a guiding part (22) connected to the wheel suspension (10), and two rotary parts, especially actuating cylinders (26, 28), arranged between the carrier part and the guiding part and rotatable in relation to each other, to the carrier part (24) and to the guiding part (22) about a common rotational axis (32). Each of said rotary parts can be moved by a drive (40) and an actuator (42) in both directions of rotation. According to the invention, the actuator (42) is designed for at least one of the rotary parts (26, 28) as a planetary gearbox (42), and the planetary gearbox (42) is especially radially externally arranged around the rotary part (26, 28).

Description

technical field [0001] The invention relates to a device according to the preamble of claim 1 for adjusting the track / spur and / or camber of a wheel of a wheel suspension arrangement, in particular for a motor vehicle. Background technique [0002] With regard to rear axle steering for (road) vehicles, different technical solutions exist. Generally, the tie rod is moved or its length is also changed. There are also embodiments with split hub brackets, as described, for example, in US 20020036385 or FR 2884795 . In this case, the rotary element or the adjusting cylinder, which determines the camber and / or the track of the wheel, is adjusted in both directions of rotation in opposite directions or in the same direction by means of an adjusting gear (for example a spur gear) and an electric motor. [0003] In the case of a multi-part adjustable wheel carrier of the type mentioned at the outset, the toe-in and / or camber are varied by corresponding rotation of the two obliquely ...
