Vehicle belt drive torsion bartender tensioner with the improved braking device

摘要

Way it turns it possesses the axis (A) the cavity which the frame which decides (3) (2) and concerning the axis (A) at least one which is installed in the frame (2) arm (4) and the idle pulley which is installed in the arm, (4) (5) and, the cavity (3) to be accommodated at least partly inside and at the same time in order the arm (4) and one body the first end (15) the torsion bar elastic member which it possesses (6) and the elastic member (6) to allow the tension attaching, the retention section (17) the second end which is connected hardness (16) with, the arm (4) the brakes in order to brake (30) with to possess the vibration, the conformity aspect(34) with it cooperates in axial direction and at the same time the conical frictional component which is loaded elastic expedient of axial direction (33) by (32) it possesses, the tensioner for the automobile belt driving device (1,50,60). The frictional component (32), the arm (4) and the frame (2) the mediating/helping equipment it is done between, the elastic member (6), depending on the twist of the elastic member, and, the frictional component (32) and the conformity aspect (34) the pushing in order to overpower, forms the axial direction thrust component.
