  • Tensioning device for the flexible or articulated element of a transmission or travelling system
    Patent number: 4949800
    Abstract: A tensioning device is provided for the flexible or articulated element of a transmission or travelling system in which the support of the hub of the wheel tensioning the flexible track is connected to the chassis of the vehicle by links comprising at each end a joint which allows pivoting in all directions. The support is pivotally mounted by a vertical pin to one end of a longitudinal arm whose length can be varied. Thus, by varying the length of said arm, the tension of the track can be adjusted, while said support is suspended by links.
