Abstract: Two guiding marks constituted by two parallel transversal marks are borne on the back of the belt, a number between said marks being indicated giving the length of the spacing required by the two markers when the belt is installed so that this belt is subjected to a suitable mounting tension. When the belt is installed, the latter is thus tensioned until the spacing of the marks reaches the given value which is simply checked by a meter rule.The invention concerns the mounting of transmission belts.
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.
