Elastomer spring to support helical spring esp. in engine bearing has centering section fitted into helical spring, bending section shear-deformed by radial forces, and stabilizer part

摘要

The spring (3) has a centering journal (10) inserted into the helical spring and a bending section (9), which is shear-deformed by radial forces. The elastomere spring is stabilized by a formed part (13). The journal is formed integrally with the bending section, and is mainly cylindrical. The journal end away from the bending section has insertion shoulders (11). The ratio of the stiffness of the elastomere spring in axial direction relative to its stiffness in radial direction, is 20 :1.
