RUBBER-METAL JOINT Russian patent published in 2011 - IPC F16F1/38 

FIELD: machine building.

SUBSTANCE: inventions refer to transport machine building, particularly to design of rubber-metal joints used in suspension of automobiles or power aggregates. The rubber-metal joint consists of an elastic element glued or vulcanised to internal accessories. The internal accessories consist of a cylinder or ellipsoid metal bushing connected along length of their external surface with a bushing with one or two ball-like or conic parts. An elastic element is additionally glued or vulcanised to the bushing made out of material with modulus of elasticity higher, than that of rubber; the bushing consists of segments and bridges. The bridges are arranged on edges of the bushing or in its middle part and connect segments of the bushing into a unit. Internal accessories of the joint are positioned in the internal part of the bushing consisting of segments and bridges and connected with it by means of rubber. According to the second version rubber-metal joint contains additional accessories rigidly joined with the internal metal bushing; these additional accessories are made out of material with modulus of elasticity higher, than that of rubber.

EFFECT: reduced axial and radial travels of internal bushing, also increased resistance of joint to destructive loads and coaxial and end torsion.
