ABSTRACT:
A centrally disposed, torsion-proof carrying tube contains a propeller shaft operatively connected to the driven axle assemblies and equipped with supports for the body of the vehicle. Each axle assembly has a spur gear differential associated therewith and comprises two bevel gear trains succeeding the differential and accommodated in a gear housing flanged to the central carrying tube. The body supports comprise at least two cross members joined to the carrying tube and two longitudinal members secured to the cross members. Each wheel is mounted on a stub axle carried by a longitudinal control arm pivoted to a cross member on an axis which is transverse to the longitudinal direction of the vehicle. Two universal-joint shafts drive the two wheels of each axle assembly. Each universal-joint shaft is associated with one of the bevel gear trains and is enclosed in a splash-proofing shell tube connected by ball-type joints to the adjacent stub axle and to the adjacent gear housing, respectively. Each shell tube is mounted at one end in an axially yieldable annular seal.
