Hydraulic-mechanical clamping system for clamping traction unit e.g. belt, in motor vehicle, has elastomer bellows utilized between housing and piston, and integral receiver receiving, collecting and/or displaying leakage quantity of fluid

摘要

The system (1) has a piston rod seal (25) sealing a storage chamber (9), and elastomer bellows (13) utilized between a housing (2) and a piston (4). Volume exchange between a pressure chamber (7) and the storage chamber takes place via a leakage gap (8) through a one-way valve (10) that is associated with a cylinder (3). The storage chamber is partially filled with hydraulic fluid and surrounds the cylinder. The leakage gap is formed between the piston and the cylinder. An integral receiver (16) receives, collects and/or visually displays leakage quantity of the spilled hydraulic fluid. The integral receiver includes an oil binding unit made from foam, sponge or felt materials.
