1,099,167. Beam axle suspensions. DAIMLER-BENZ A.G. April 22, 1966 [April 23, 1965], No. 17731/66. Heading B7D. In a vehicle spring suspension comprising an axle 10 mounted on a single longitudinal member 13 which is pivotable relative to the vehicle frame 20 about both longitudinal and transverse axes, the central longitudinal axis 21 passes above the transverse axis 15 which is at wheel centre height and separate springs are provided for resisting pivoting of the member 13 about each axis. The longitudinal member 13 is of box-shape in plan with axle securing lugs 12 at the rear corners and is pivoted at the front corners to the base 22 of a fork member 14 comprising two triangular frames 16, 17 and the common base 22. The top of frame 17 is pivoted to the vehicle frame 20 on a pin 18 and forms an abutment for one or a pair of coil or pneumatic springs 25 mounted on the member 13 for controlling pivoting of the axle 10 about the axis 15. The top of the frame 16 is secured to and pivots on one end of a torsion bar spring 23 which resists pivoting of the axle 10 about the axis 21. In alternatives (Figs. 3, 4, not shown), the top of the frame 16 is pivotable on a pin (28) on the axis 21 and pivoting about this axis is resisted either by a rectangular section torsion bar mounted eccentrically of the pin (28) or by a pair of helical or rubber springs (26) mounted on the frame sides to contact shoulders (27) on the frame member (14). |
