Self-aligning pendulum with spring-point displacement by wedge principle, endless traction mechanism and setting method for adjusting the clamping force of a pendulum clamp

摘要

The invention relates to a pendulum tensioner (1) for tensioning a endless traction means of a traction mechanism, with a first tensioning roller (2) which is rotatably provided on a housing lever (3) for contacting the endless traction means, and with a second tensioning roller (4) on a to the housing lever (3) via a bow spring (6) displaceable ring lever (5) is rotatably mounted to also contact the endless traction means, wherein the bow spring (6) with its two ends depending on a spring system (7) is supported, of which a spring system (7) is fixed to the housing and the other spring system (7) is fixed to the ring lever, wherein a wedge mechanism (9) acting on at least one of the two spring systems (7), that the acting length of the bow spring (6) is adjustable , The invention also relates to a endless traction drive for a motor vehicle with a continuous traction means, which surrounds a drive and / or output shaft, which is encompassed by a pendulum clamp (1) of the inventive type, the pendulum clamp (1) the endless traction means so from two sides contacted that the endless traction means is tensioned. The invention also relates to a setting method for adjusting the clamping force of a pendulum clamp (1) of the type according to the invention, wherein on the adjusting screw (11) the torque is measured to draw conclusions about the effective length of the bow spring (6).
