671,811. Resilient mountings; assembling rubber bush mountings. GENERAL TIRE & RUBBER CO. Aug. 2, 1950 [Aug. 9, 1949], No. 19314/50. Class 108(iii) In a rubber joint or bushing comprising an outer rigid tubular member 2, having a generally cylindrical inner surface portion 4, an inner rigid tubular member 1 having a generally cylindrical outer surface portion 6 and a separately moulded and vulcanized rubber annulus 3 under relatively high radial compression and axial elongation between the members, end portions 5 of the inner surface of the outer member are outwardly flared to provide generally frusto-conical surfaces, the end portions of the inner member are outwardly flared to provide generally frusto-conical surfaces spaced from the frusto-conical surfaces of the outer member, and the end portions of the rubber annulus are outwardly flared and the generally cylindrical areas of the inner and outer rigid members 1 and 2 are relatively large compared with the frustoconical surfaces thereof. In the arrangement shown in Fig. 3, the components of the bushing shown in Fig. 2 are assembled in known manner and the ends of the inner member 1 are then flared out by means of flaring members 20 which are moved into the member 1 axially of the bushing. In the application to a support between mounting and mounted members of a vehicle suspension, Fig. 1, (not shown), the assembled bushing is disposed in an eye of a frame portion and the inner member 1 of the bushing is connected to a mounting member by a pair of links clamped to the ends of the inner member by a bolt. The surfaces of the links which engage the ends of the inner member are complementary to the inner surfaces of the flared ends of the inner member. |
