Automatic nut running to torque without the possibility of slip

摘要

A shock absorber has a pressure tube, a piston slidably disposed in the pressure tube and a piston rod attached to the piston and extending out of the pressure tube. The end of the piston rod extending out of the pressure tube defines a contoured surface which can be engaged to prohibit rotation of the piston rod. In one embodiment the contoured surface is defined by an inner surface of a bore. In another embodiment, the contoured surface is defined by an exterior surface of an extension to the piston rod.
