  • Patent number: 4916966
    Abstract: Shifting apparatus for power transmissions incorporating vibration damping elements whereby vibrations occurring within the transmission are substantially isolated from the shift lever extending into the vehicle cab. A homogeneous vibration isolator body is mounted to the end of a shift lever. The body includes a spherical segment bearing surface and a cylindrical bore receiving a gear shifting stem. Elastomeric vibration damping rings interposed between the stem, which is pivotally mounted on the body, and the body absorbs and isolates vibration, while metal-to-metal contact between the stem and body is possible upon maximum compression of the elastomeric elements occurring.
