Pull type hydraulic actuator friction clutch

摘要

In an hydraulically operable system for disengaging a pulled friction clutch a cylinder (3) and, disposed at a radial distance from it, a bearing support (5) are disposed concentrically of the gearbox input shaft and the cylinder (3) is fixed on the gearbox. A tension spring (33) is connected by a spring support (37) to the cylinder (3) and by a further spring support (35) to the bearing support (5). The spring supports (35,37) are constructed as tubular telescopically inter-engageable sleeves, the spring support (35) which is connected to the bearing support (5) forming a snap-action connection together with the bearing support. At least one spring support (35,37) comprises at least one extending projection (51,53) which serves as a bracing surface for the tension spring (33).
