827,261. Road vehicle undercarriages; springs. DAIMLER-BENZ A. G. Oct. 31, 1957 [Oct. 31, 1956], No. 34059/57. Classes 108(2) and 108(3) [Also in Group XXXI] A motor vehicle main frame 11, Fig. 1, is mounted on two resilient bearers 23, 24 in an auxiliary frame 14 carrying the front wheel spring suspension system and which is supported against longitudinal forces and braking movements by a pair of longitudinal rods 25, 26 disposed symmetrically about the vehicle axis and connected to points on the auxiliary frame 12 at a vertical distance from the bearers 23, 24. Each bearer 23 comprises a cupped rubber pad 50, Fig. 5, located in a recess 48 in the auxiliary frame 14 and engaged by a projection 49 on the main frame 11. The parts 49, 50 are connected by a bolt 55 having a rubber pad 52 under its head, the compression of which is limited by a sleeve 56. The rods 25, 26 are connected to the front wall 27 of the vehicle through lock-nuts 43 and intermediate resilient bushes 40 and are connected to the tops of vertical cylindrical members 30, Fig. 3, forming the ends of the frame 14. Resilient connections to the member 30 are provided by rubber bushes 29 located between flanges 31, 32 and encircled by straps 28 which are bolted to the rods 25, 26. Adjustments of the length of the rods 25, 26 by the lock-nuts 43, provide adjustment of castor angle. The wheels 12 are connected to the frame 14 through links 15, 17, Fig. 2, and shock absorbers 34 are connected between the lower links 17 and rubber bushes 38 at the top of the cylindrical member 30. Additional support for the frame 14 is provided by a cranked torsion bar 57 mounted in resilient bushes 59 on a frame cross-member 66 and engaging further resilient bushes 58 at the ends of the auxiliary frame 14. In modifications where reduced resilience is provided between the frames 11, 14 by unconfined rubber bushes or pneumatic cushions, Figs. 8, 9 (not shown), additional transverse support between the frame is provided by transverse rods 74, Fig. 10, connected to the frames through small rubber cushions 75, 76. |
