Linearly acting clamping unit for traction mechanism for automatic adjustment of bias voltage of belt drive of internal combustion engine, has spring with ends directly or indirectly aligned at piston and cylinder supported on lugs

摘要

The unit (1a) has a pressure spring (9a) with ends (10a, 11a) directly or indirectly aligned at a piston (3a) and a cylinder (2a) supported on pivot lugs (7, 8), respectively. The pressure spring is inserted between the piston and a piston rod (4a), and a separate cover of the cylinder is guided in a base (6). Clamping units include damping devices for attenuation of position movements of a traction drive, where the damping devices have a friction lining or a friction element. The clamping units are made of plastic.
