Abstract: The invention relates to a spring element (11) that is designed for a flexible drive of an internal combustion engine. The spring element (11) comprises a cylinder (12), in which a piston (13) is guided in a linearly displaceable manner, a force being applied to said piston by spring means (17). Corresponding fixing eyes (15, 16) are respectively allocated to the cylinder (12) and the piston (13) for fixing the spring element (11). A transverse pin (29) is associated with the piston (13) to limit the travel of the spring element (11), said pin engaging in a positive fit with backlash in a longitudinal guiding element (30a, 30b) of the cylinder (12).

Abstract: A tensioner enables easy and reliable reinstallation of the tensioner and belt in the field service while simultaneously making it possible to utilize a one-way clutch device to ensure continuous belt tension control without cumbersome manual alignment and/or realignment procedures. The tensioner has a pivot shaft configured for mounting on an engine surface. A tensioner arm is mounted on the pivot shaft for pivotal movement between a free arm stop position and premount stop position. A belt-engaging pulley is mounted for rotation on the tensioner arm. A base cup is rotatably mounted around an end of the pivot shaft. The base cup has an arcuate slot having a free arm stop end and a premount stop end. The tensioner arm cooperates with the arcuate slot limiting the pivotal movement of the tensioner arm. A spring is coupled between the tensioner arm and the base cup biasing the tensioner arm in a belt-tensioning direction. An anti- kickback stop mechanism engages the pivot shaft and has a lost motion connection with the tensioner arm wherein the tensioner arm moves through a free range without engaging the anti-kickback mechanism. The tensioner arm 1) rotates the anti-kickback mechanism as the tensioner arm moves beyond the free range towards the premount stop position and 2) enables the anti-kickback mechanism as the tensioner arm moves beyond the free range towards the free arm stop position, limiting travel of the tensioner arm therebeyond. The spring is fixable relative to the pivot shaft upon the tensioner being mounted on the engine surface.

Abstract: A tensioner for tensioning a flexible drive means, such as a timing belt or chain, includes a pulley to contact the belt. The pulley is mounted on a tensioner arm and the tensioner arm can be rotated about a pivot shaft mounted to the tensioner by a spring. The axis about which the pulley rotates is spaced from the axis of the rotation of the tensioner arm with respect to the pivot shaft and the spacing of these axes of rotation results in the pulley moving through an eccentric towards or away from the belt when the tensioner arm is rotated. A stop is used to limit the range of movement of the tensioner arm between a desired range of movement defined by a free arm stop and a backstop. The position of the stop is adjustable by an installer. The angular range of movement of the tensioner arm is adjustable from a position suitable for installation of the tensioner to a position suitable for operation of the installed tensioner. In one embodiment, the movement of the stop from the installation position to the nominal operating position also compensates the spring.
