Problems solved by technology

However, the wheel suspension kinematics described in this document are too restrictive and are not functionally reliable in practice, since jamming of the guide parts relative to the rail parts can occur

Embodiment Construction

[0021] The wheel carrier for the (not shown wheel) is denoted by reference numeral 3 and supports an air spring part 8 via an arm 4d, which has a combined and therefore invisible damper on which the vehicle body is supported. device. In addition, a total of three so-called guide elements 5 a , 5 b , 5 c are fastened to the wheel carrier 3 via additional arms 4 a , 4 b , 4 c which are only partially visible, wherein each arm carries one such guide element, the structure of which is shown below Also discussed in detail. A solid so-called guide rail part 6a extends substantially in the vertical direction V through two rear guide parts 5a, 5b seen in the direction of travel FR, which guide rail part 6 acts on both ends of the guide rail part 6. The fixing clip 7 is fixed on the vehicle body (not shown). A further solid guide rail part 6b extends substantially in the vertical direction V through the front guide part 5c seen in the direction of travel FR in a similar manner, which...

Abstract

The invention relates to an independent suspension of a double-track vehicle, especially a car, which has a wheel guiding system that is formed by at least two solid guide rail components and some guide components that can move along the guide rail components. In front of and behind the center, there is respectively at least one guide rail part extending substantially in the vertical direction. The guide rail part can be formed rectilinearly or curved with a constant or varying curvature along the guide rail. The guide part can have rolling bodies formed as cylindrical or barrel-shaped rollers, which are mounted in a carrier and roll on correspondingly flat or substantially U-shaped guide rail parts in cross section. Preferably, two or three rolling bodies are respectively provided on substantially or approximately opposite sides of each guide rail part, but instead of them sliding parts can also be provided.

Description

technical field [0001] The invention relates to an independent suspension of a double-track vehicle, especially a passenger car, which has a wheel guide system cooperating with a guide rail part made of a solid body and guide parts movable along the guide rail part. For the known prior art, apart from the usual independent suspension with link arms and apart from German patent document 613 775 or US patent 2,992,013, see in particular DE 295 19 108 U1. Background technique [0002] Conventional independent suspensions meet the kinematic and elastokinematic requirements for vehicle wheel guidance systems with link arms and articulating kinematic chains, which guide the wheel carrier and in turn guide the wheel relative to the vehicle body. For example, the double wishbone principle and its variants, such as a three-arm suspension axle or a five-arm suspension axle, already meet the high demands in terms of driving dynamics and driving comfort. Here, on the one hand, the arra...
