Steerable front axle for motor vehicles
First Claim
1. Steerable front axle for motor vehicles, comprising a steering knuckle for each of the two front wheels which is rotatably mounted on at least one axle connecting rod pivoted on the chassis via a connecting rod bearing, in which the axes of rotation of the connecting rod bearings are essentially arranged in the longitudinal direction of the motor vehicle, and one steering tie rod each associated with each of the front wheels, which steering tie rod is linked with a steering tie rod lever connected to the corresponding steering knuckle, in which a steering mechanism connected to the steering tie rods is arranged between the two steering tie rods, characterized in that, for hydraulic length adjustment, the steering tie rods have an expansion chamber to which a hydraulic fluid can be admitted and that both the connecting rod bearings associated with each of the front wheels have a hollow displacement zone between the junction points of the axle connecting rod and the chassis which displacement zone is compressible in the longitudinal direction of the vehicle and in which the hydraulic fluid is housed which enters the expansion chamber of the steering tie rod of the associated front wheel via a hydraulic tube in the case of the compression of the displacement zone which occurs during braking.

Abstract
The present invention pertains to a steerable front axle for motor vehicles with a steering knuckle for each of the two front wheels, which steering knuckle is pivotedly mounted on at least one axle connecting rod supported pivotedly on the chassis via a connecting rod bearing. The axes of rotation of the connecting rod bearings are essentially arranged in the longitudinal direction of the vehicle. A steering tie rod, which is linked with the corresponding steering knuckle, is associated with each of the front wheels. A steering mechanism connected to the steering tie rods is provided between the two steering tie rods. The steering tie rods have an expansion chamber for the hydraulic length adjustment, into which hydraulic fluid can be admitted. Both of the connecting rod bearings associated with each of the front wheels have a hollow displacement zone which can be compressed in the longitudinal direction of the vehicle, in which the hydraulic fluid is located which will enter the expansion chamber of the steering tie rod of the associated front wheel via a hydraulic tube in the case of the compression of the displacement zone which occurs during braking.
