Tensioning module, in particular neutral point tensioning module

摘要

The module has an actuating element (30) and/or a tensioning slide (26) comprising guiding grooves (46, 48), which lie in planes running toward motion direction of the tensioning slide. The guiding grooves symmetrically run with respect to a middle longitudinal axis (28). Guiding cams (50, 52) at the tensioning slide and/or at the actuating element are engaged with the guiding grooves. The actuating element is formed at free end of a piston rod (32) of a pressure-accelerated piston (34). The tensioning slide is arranged along a radial line.
