829,158. Resilient mountings. GENERAL MOTORS CORPORATION. Jan. 20, 1958 [Feb. 12, 1957], No. 1837/58. Class 108(3) [Also in Group XXXI] A spring 40, Fig. 3, for connecting a wheel suspension member 18 to a vehicle side rail 14 comprises a resilient ring 64 of elastomeric material which is radially compressed between concentric sleeves 62, 66 to increase the radial rate of load deflection. The sleeve 66, Fig. 5, comprises semi-cylindrical sections which are received within an outer sleeve 60 which maintains the material in compression and is welded to brackets 112 on the cross-member 18. A flanged end 68 of the ring 64 has radially disposed ribs 74 which are engaged between flanges 72 and a frame plate 56 to provide damping during large axial deflections. A resilient ring 76 with similar radial ribs 82 is attached to an endplate below the mounting to minimize axial deflections in the opposite direction. In a modification the resilient ring is built up from a number of annular pads of spring wire mesh. |
