Definitions

  • the strut is designed as a rigid axle and connects the flanges of the wheels with each other.
  • the trailing arms are connected with one end directly to the strut.
  • Suspension struts of the spring / damping device are supported on the Watt linkage.
  • this suspension has only a low ride comfort.
  • the Watt linkage leads to an entry of steering forces in the side members.
  • the invention is based on the problem, a suspension of the type mentioned in such a way that it is an entry of steering forces in the trailing arm largely avoids the Watt linkage and allows the highest possible comfort of the motor vehicle. Furthermore, the invention is based on the problem to provide a motor vehicle body with a suspension, which allows the highest possible driving comfort.
  • Another advantage of the invention is that the transverse profile can be replaced by a light and simple, preferably rotationally symmetrical, Irish profile. This leads to particularly low production costs of the strut.
  • the trailing arm and the strut are formed as a beam axis with a spaced from flanges for supporting the wheels connection of the strut to the trailing arms.
  • the opposite arrangement of the two Watt linkage designed according to an advantageous embodiment of the invention structurally particularly simple, if Watt linkage each have a mounted on the vehicle body rocker and when the rockers and the rockers with the trailing arms connecting elements of the Watt linkage are arranged in mirror image to each other.
  • a particularly high ride comfort is achieved according to another advantageous embodiment of the invention, when Wipplager the rockers are designed to be more flexible on the body part in the intended direction of travel of the motor vehicle as transverse to the intended direction of travel.
  • the Wipplager on a common bearing axis and are formed longitudinally elastic or elastically held in the intended direction of travel of the motor vehicle.
  • the second-mentioned problem namely the creation of a motor vehicle body with a suspension, which allows the highest possible driving comfort, is inventively achieved in that two Watt linkage are provided, which each connect the trailing arm together and that the Watt linkage are arranged in opposite directions.
  • Trailing arm introduced steering forces on each other. This leads to a particularly high ride comfort. Furthermore, this allows the trailing arm interconnecting strut make particularly easy and inexpensive to manufacture.
  • An understeer of the motor vehicle can be according to another advantageous embodiment of the invention easily avoided when Anlenklager the elements of the Watt linkage are arranged on the trailing arms in the intended installation position of the suspension above rocker bearings of the rockers.
  • Oversteer of the motor vehicle can be easily avoided according to another advantageous embodiment of the invention, when Anlenklager the elements of the Watt linkage are arranged on the trailing arms in the intended installation position of the suspension below rocker bearings of the rockers.
  • a roll camber loss of the suspension can be easily avoided according to another advantageous embodiment of the invention, when the elements are articulated to the trailing arm deeper than on the rocker and arranged as deep as possible.
  • a roll camber loss of the suspension can be increased according to another advantageous embodiment of the invention, when the elements are articulated to the trailing arm deeper than on the rocker and arranged as high as possible.

Abstract

Suspension (3) de roue pour roues (2) non guidées d'un véhicule automobile présentant deux tiges (14, 15) actives pour relier des bras (9) oscillants longitudinaux d'un axe (7) de bras oscillant transversal composite. Les tiges (14, 15) actives sont disposées à l'opposé l'une de l'autre et logées de manière flexible dans le sens longitudinal du véhicule automobile. Cela permet d'éviter efficacement l'induction de forces de direction dans les bras (9) oscillants longitudinaux.
