Embodiment Construction

[0020] 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 wheel suspension of a two-track vehicle, especially a private car, providing wheel guidance system by means of at least two solid guideway elements in conjunction with guiding elements that can be displaced along the same. At least one guideway element extending essentially in the vertical direction is respectively provided at the front and the rear of the wheel centre. The guideway element can be embodied in a linear or curved manner, with a curvature which is constant or varies along the guideway. The guiding elements can comprise rolling bodies which are embodied as cylindrical or barrel-shaped rolls, are mounted in a carrier, and roll on a corresponding guideway element which is plane or has an essentially U-shaped cross-section. Preferably, respectively two or three rolling bodies, instead of which sliding elements can also be used, are provided on essentially or approximately opposing sides of each guideway element.

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, besides the usual independent suspension with links, see German patent document 613775 or US patent 2,992,013. 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. On the one hand, the configuration of the links and joints enables the kinematic para...
