Abstract
Official abstract text for this publication.
A motor vehicle multi-link axle having wheel suspension including a lower transverse link and an upper transverse link. A leaf spring extending transversely to a direction of travel of the vehicle and below the upper transverse link. A link element connects an end of the leaf spring to the upper transverse link. The link element having a first connection, connected to the upper transverse link, and a second connection, connected to the leaf spring. The link element adjustable to vary the distance between the first connection and the second connection. The multi-link axle may also include a connecting element that connects the second connection point of the link element to a connection point of the leaf spring, with the connecting adjustable to vary the distance between the second connection point of the link element and the connection point of the connecting element to the leaf spring.
First claim
Opening claim text (preview).
What is claimed is: 1. A multi-link axle for a vehicle comprising: a wheel suspension including a lower transverse link and an upper transverse link, the upper and lower transverse links connected to a wheel carrier; a leaf spring extending transversely to a direction of travel of the vehicle, said leaf spring being running below the upper transverse link; a link element connected at a first connection to the upper transverse link; a connecting element connected at a second connection to the leaf spring, said link element and said connecting element connected at a third connection to each other; and an actuator adjusting a distance between the third connection and the second connection. 2. The multi-link axle of claim 1 wherein the distance between the second connection and the third connection is adjustable in a substantially horizontal direction. 3. The multi-link axle of claim 1 wherein the connecting element is a length-adjustable actuator varying the distance between the second connection and the third connection. 4. The multi-link axle of claim 1 wherein the actuator is a hydraulic, linear actuator. 5. The multi-link axle of claim 1 including an adjuster, said adjuster varying a distance between the first connection and the second connection.
