Independent vehicle suspension having a spring-link suspension structure made from a fiber composite material

摘要

An independent suspension for a vehicle includes a spring-link suspension structure which is made from a fibrous composite material, is substantially U-shaped when viewed in the vehicle longitudinal direction. Ends of upper and lower members are secured to the vehicle body or a carrier connected thereto. At least one of these securements has no rotational degree of freedom about an axis extending in the vehicle longitudinal direction, while a wheel hub is connected to the base of the U-shaped spring-link suspension structure in order to secure a vehicle wheel. At least one of the members is secured to the vehicle body or to the carrier in a substantially rigid manner i.e. aside from low levels of elasticity, and no further wheel guiding suspension link is provided that substantially extends in the vehicle longitudinal direction. As a result, in order to achieve a desired toe-in increase when braking, a recess is provided in at least one of the members. The recess extends from the point at which the wheel hub is secured to the base and across only a subregion of the member in the longitudinal direction thereof.

主权项

1. An independent suspension of a vehicle, comprising:
a spring-link structure formed of a composite fiber material and configured to have a substantially U-shape viewed in a longitudinal direction of the vehicle, wherein the spring-link structure comprises an upper member and a lower member as well as a base member connecting the upper and lower members, the upper and lower members being secured at end sides thereof to a vehicle body or a carrier connected to the vehicle body, at least one securement not having any degree of rotational freedom about an axis extending in the longitudinal direction of the vehicle; a wheel hub connected to the base of the U-shaped spring-link structure in order to secure a vehicle wheel; wherein at least one of the upper and lower members is substantially rigidly secured to the vehicle body or to the carrier, and no additional wheel guiding link is provided that extends substantially in the longitudinal direction, and a recess arranged in at least one of the upper and lower members, the recess extending from the connection of the wheel hub to the base only over a part-region of the member in a longitudinal direction of the member in order to achieve a desired increase in toe-in during braking.
