680,984. Spring suspensions. DAIMLERBENZ AKT.-GES. June 13, 1951 [June 13, 1950], No. 14040/51. Class 108 (ii). In an arrangement for suspending a rigid axle, sprung for example by helical springs, on a vehicle frame a by means of two superimposed links d<1>, d<2> and e<1>, e<2> swinging in longitudinal planes, one of the two links d<1>, d<2> is connected to the frame a pivotally about a transverse axis f<1>, f<2> only and to the rigid axle b pivotally in all directions (or at least about a transverse axis and a longitudinal axis) and the other link el, e<2> is connected to the rigid axle pivotally about a transverse axis h<1>, h<2> only and to the frame pivotally in all directions (or at least about a transverse axis and a longitudinal axis). In the arrangement shown, the helical springs may be located between the frame and the axle b or between the frame and one of the links. Alternatively torsion rod springs may be disposed in the pivot axis f<1>, f<2>. In other arrangements, Figs. 4 and 5 (not shown), the links, as seen in side elevation, may be divergent from the axle towards the frame, or may converge thereto and lie on a common joint axis. The links may intersect intermediate their ends. In another arrangement (Fig. 6, not shown), the links extend obliquely upwardly or downwardly from the frame in the normally loaded position of the vehicle. In further arrangements, Figs. 7 and 8 (not shown), the links are connected to the axle respectively above and below the axle. In other arrangements (Figs. 9 and 19, not shown), the lower and upper links respectively are connected to the axle on the axis thereof. In all cases the links may extend parallel to each other and horizontally or at an inclination to the horizontal. The universal link connections may be of rubber. One link may be connected forwardly and the other rearwardly. The invention is applicable to driven or driving wheels.
