Abstract

This invention relates to a suspension of an axle gear casing for motor vehicles comprising at least two elastic suspension elements, with one of the suspension elements arranged in front of the axle shaft and the other one arranged behind the axle shaft, in alignment with one another in the longitudinal direction of the vehicle and offset to the side of the longitudinal axis of the gear casing, wherein coordination of the stiffnesses of the suspension elements causes a rotating movement of the axle gear casing opposing a movement of the axle gear casing that occurs under the influence of the driving reaction moment from the vehicle wheels and engine drive and which normally shifts the front end of the casing correspondingly in the upward direction to maintain the position of the drive shaft of the axle gear with respect to a center of a flexible disk of a driving cardan shaft to ensure that a change of angle between the drive shaft and the cardan shaft is limited to a tolerable extent.
