Hydraulic circuit for controlling a hybrid clutch and an automatic transmission of a motor vehicle

Abstract

A hydraulic circuit for controlling a hybrid clutch and an automatic transmission of a motor vehicle. The circuit includes an electrically-powered hydraulic pump to supply the hybrid clutch and the automatic transmission with a hydraulic medium. A pressure booster is connected downstream of the hydraulic pump and includes a pressure booster slave cylinder and a pressure booster master cylinder. A hydraulic line segment extends between the pressure booster and the hybrid clutch, with the pressure booster master cylinder connected with a hybrid clutch slave cylinder to actuate the hybrid clutch. An oil feed device is connected with the pressure booster slave cylinder and fed by it with the hydraulic medium for refilling the hydrostatic line segment with the hydraulic medium.
