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

Abstract

DC60 (06/06/60) in vehicle power units. Where the clutch is arranged between the engine and the kit Transmit power so that it will be brought into the transmission state at the time of the hydraulic cylinder operation. The drive loss of this engine has been reduced, although the clutch has been preserved in State connected by hydraulic cylinder And resulted in a reduction in fuel consumption of That engine has been made. The electromagnetic on / off valve 40A, 40B are integrated into the path. Through of the oil for connection 39A, 39B, which is connected between the oil pump 36, which is driven by the electric motor 37, and the hydraulic cylinder 35A, 35B and the control unit C, which controls the operation of the electric motor 37 and the on / off valve. The electromagnetic 40A, 40B shut off the electromagnetic on / off valve 40A, 40B to cause the oil pressure in the 35A, 35B hydraulic cylinder to be maintained and Stop the operating of the 37 electric motor during the clutch connection 15A, 15B in the vehicle power unit, in which the clutch is set up between the engine and the powertrain so that it is brought to the transmitted state. Power at the time of operation of the hydraulic cylinder The drive loss of this engine has been reduced even though these clutches have been preserved. In the connected state by these hydraulic cylinders And its effect on the reduction in fuel consumption Of that engine has been made The electromagnetic on / off (40A, 40B) valves are integrated into the Oil path 39A, 39B for connection, which connects the fuel pump 39, which is 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 open / valve. The electromagnetic mute 40A, 40B closes this electromagnetic on / off valve 40A, 40B to cause the oil pressure in this 35A, 35B hydraulic cylinder to be stabilized. Maintain and stop operation of this 37 electric motor during clutch connection 15A, 15B.
