PURPOSE:To switch and connect a hydraulic clutch smoothly and safety by providing clutch connecting means in which brake operating means is automatically operated according to a selected signal from a control unit. CONSTITUTION:A car velocity detecting means 14 is connected to a control unit 13, and a clutch connecting means 11 is provided with a solenoid proportional control valve 6 for a brake, which is controled according to a signal from a control unit 13, so that the solenoid proportional control valve 6 is automatically controlled according to a signal from the control unit 13. In this arrangement, speed reducing operation and reversing operation by a selector valve 2 can be performed with a clutch plate having a small energy absorbing quantity instead of a driver's direct braking operation. Therefore, a hydraulic clutch can be switched and connected smoothly and safely. |
