  • Device for damping vibrations in a gear change mechanism for vehicles
    Patent number: 4777839
    Abstract: In vehicles, it is usual that vibrations and noise occurring in the vehicle engine and transmission are propagated to the gear change lever via a transmission rod. To surmount these problems, an improved transmission rod consists of two axially separated parts, which are connected to each other via an articulation allowing transfer of both angular and axial movement between the rod parts. A spring element is arranged in a radial direction on each side of the articulation. The spring elements are in mutual co-action via a stiff connection which surrounds the spring elements and the articulation and is separated from the transmission rod parts by the spring elements.
