Abstract: An automotive tension device features a pair of pulleys which are pivotally mounted on the same pivot arm. The pulleys are positioned within the drive system (e.g., a belt drive system) in such a manner that the moments relative to the pivot axis created by the force resultant of the driving member passing around each of the pulleys are oppositely directed. Thus, the pulleys provide rotational support for each other. The tension device and arrangement is positioned within a belt drive system having a combination starter/generator, wherein the crankshaft ordinarily drives the belt but the starter/generator drives the belt on engine startup (an arrangement which creates varying kinematic conditions within the belt). One of the pulleys bears against a first, crankshaft-driving portion of the driving member extending from the crankshaft pulley to the starter/generator pulley on the driving side of the crankshaft, and the other pulley bears against a second, starter/generator driving portion of the driving member extending from the starter/generator pulley to the crankshaft pulley on the driving side of the starter/generator pulley.

Abstract: The invention relates to an automatic belt tensioner comprising a basic part that is connected to a tensioning part so as to be rotatable about a common axis of rotation, a helical spring that is joined to the basic part and the tensioning part, and a wrapping bush which is wrapped at least in some areas with a radial enveloping force by means of the helical spring. According to the invention, the material of the wrapping bush contains reinforced plastic in order to ensure that the belt tensioner provides good damping and good cushioning properties if possible during the entire service life thereof while being universally usable and having a simple design.

Abstract: The present invention relates to a tensioner (1) for an endless drive, in particular of an internal combustion engine, wherein the tensioner has base part (2) and a clamping part (3) which can rotate relative to the former, a spring element (11) which is arranged between the base part and the clamping part (3) so as to impart a force, and a friction apparatus (12) which is provided between the spring element (11) and the base part or the clamping part (3) and by way of which the relative movement between the base part (2) and the clamping part (3) is damped. In order to improve a tensioner of the generic type in such that a simple construction is possible with satisfactory clamping, it is proposed to arrange the friction apparatus (13) radially outside the spring element (11).
