Hydraulic traction means clamps with a bypass - channel - closing means with a linear a temperature-dependent expansive behavior

摘要

The invention relates to a hydraulic traction means clamps (1) for clamping a continuous traction mechanism, with a housing (2), in which a is provided for displacing a clamping rail can be extended to the piston (3) is guided, wherein a hydraulic fluid - supply channel (4) to a between the housing (2) and the piston (3) arranged hydraulic fluid - chamber (5) is provided, wherein a hydraulic fluid - the discharge channel (13) on the hydraulic fluid - chamber (5) is connected in order to an overpressure, hydraulic fluid from the hydraulic fluid - chamber (5) to discharge, wherein a expands as a function of temperature by flow influencing member (15), thus, to the hydraulic fluid - the discharge channel (13) is provided that the hydraulic fluid - the discharge channel (13) in the case of a rise in temperature is reduced or is closed and opened at a temperature drop is increased or. The present invention also relates to a traction mechanism drive comprising an endless traction means, which is in contact with a tensioning rail, whereby the tension rail of a traction means clamps (1) of the type according to the invention can be deflected.
