Abstract
To disengage a clutch using the clutch actuation in the event of a failure of the system, having pedal force-assisted pressurization of the hydraulic system, composed of two hydraulic circuits, a master cylinder and a slave cylinder being essentially disposed in the first circuit, and an electromotor-driven pump being in the second circuit, and the two circuits communicating with one another in a mutually controllable fashion via a valve block having a pressure slide valve and a pressure-valve spring, an emergency release mechanism is provided in the hydraulic system.
Claims6
A hydraulic system having pedal force-assisted pressurization, comprising:
- a first and a second hydraulic circuit for a clutch actuation, a master cylinder and a slave cylinder being disposed in the first hydraulic circuit, and a pump driven by an electromotor being disposed in the second hydraulic circuit;
- a valve block, the first and second hydraulic circuits communicating with one another in a mutually controllable fashion via the valve block, the valve block having a pressure slide valve and a pressure-valve spring;
- and
- an emergency release mechanism for the clutch provided in the hydraulic system.
