Abstract
A rear axle assembly for motor vehicles with an axle being of rigid design, running at right angles to the lengthwise axis of the vehicle is pivotably mounted to the vehicle body by a support bearing located on the central lengthwise axis of the vehicle and by guide bearings via two trailing arms connected to the axle beam, the axle beam being held away from the vehicle body shock absorber struts. The trailing arms and axle beam are connected to form a one-piece wheel guiding element for the rear wheels of the vehicle which are carried by the axle beam in a manner achieving an instantaneous rotational pole that is located rearward of the rotational axis of the wheels carried by the axle beam, with respect to a forward direction of travel, and the guide bearings being transversely flexible, permitting a roll steering effect of the rear wheels and forming a horizontal pivot axis for the assembly which runs in front of the wheels' rotational axis relative to said forward direction of travel, during straight line travel of the vehicle, but extends approximately between the support bearing and one of the rear wheels of the vehicle as said vehicle travels through a curve. The support bearing is constructed so as to be flexible in horizontal load directions, but rigid in vertical load directions, while the guide bearings are axially elastic and radially rigid.
