TH59846B - Clutch control system in the vehicle power unit - Google Patents

Abstract

DC60 (06/06/60) In a vehicle power unit, where a clutch is provided between the engine and the transmission so that it is brought into the transmission state at the time of operation of the hydraulic cylinder, this loss of engine drive is minimized, although the clutch is maintained in the connected state by the hydraulic cylinder, and the effect on the reduction of engine fuel consumption is achieved. Electromagnetic on/off valves 40A, 40B are integrated into the oil passage for the connection 39A, 39B, which connects the oil pump 36 driven by the electric motor 37 and the hydraulic cylinders 35A, 35B and the control unit C, which controls the operation of the electric motor 37 and the electromagnetic on/off valves 40A, 40B, the electromagnetic on/off valves 40A, 40B are closed so that the oil pressure in the hydraulic cylinders 35A, 35B is maintained and The operation of the electric motor 37 is stopped during the coupling of the clutches 15A,15B in the vehicle power unit, wherein the clutch is provided between the engine and the transmission so that it is brought into the power transmission state at the time of operation of the hydraulic cylinders. This loss of engine drive is minimized, although these clutches are maintained in the coupling state by these hydraulic cylinders, and the effect on the reduction of engine fuel consumption is achieved. An electromagnetic on/off valve (40A,40B) is inserted into the path of the oil pump 39,39B for the coupling which connects the oil pump 39 driven by the electric motor 37 to the hydraulic cylinders 35A,35B and the control unit C which controls the operation of the electric motor 37 and the electromagnetic on/off valves 40A,40B. This electromagnetic on/off valve 40A,40B is closed so that the oil pressure in the hydraulic cylinders 35A,35B is maintained. Maintain and stop the operation of this 37 electric motor during the connection of clutch 15A,15B.
