Abstract: The clutch control device comprises: a pump that feeds oil to a hydraulic clutch; a control part that controls the pump; an input-side oil channel through which oil suctioned into the pump from an oil tank passes; an output-side oil channel connecting the pump and the hydraulic clutch; a pressure sensor; a connecting oil channel connected to the input-side oil channel and the output-side oil channel; and a solenoid valve that interrupts or allows the flow of oil in the connecting oil channel. The opening degree of the valve can be adjusted. When a drive shaft and a driven shaft are connected by the hydraulic clutch, the control part adjusts the opening degree of the valve on the basis of the pressure of oil in the output-side oil channel and the number of rotations made by the driven shaft while monotonically increasing the number of rotations of the drive part.

Abstract: A clutch control device includes a pump to feed oil to a hydraulic clutch, an input side oil passage connecting an oil tank and the pump and through which oil sucked from the oil tank to the pump passes, and an output side oil passage connecting the pump and the hydraulic clutch and through which oil that is pressurized by the pump and is fed from the pump to the hydraulic clutch passes. A damper connected to the input side oil passage and the output side oil passage includes an oil container containing oil, a partition that partitions the oil container into first and second spaces along a predetermined direction and at least a portion of which is movable in the predetermined direction, a first connection oil passage connecting the first space and the input side oil passage, a second connection oil passage connecting the second space and the output side oil passage, and an elastic portion that applies a force to the partition to move the partition toward the second space in the predetermined direction.

Abstract: There is provided a clutch control device which includes an electric oil pump, a clutch unit, and a pressure measurement unit, and which controls an operation of the electric oil pump so as to change a transmission state of the clutch unit. The device includes a pressure control valve that is located between an oil passage for connecting the electric oil pump and the clutch unit to each other and an oil pan for storing an unpressurized hydraulic oil, and that discharges the pressurized hydraulic oil from the oil passage to the oil pan, when pressure of the hydraulic oil exceeds valve opening pressure, and a pump drive control unit that controls hydraulic pressure by driving the electric oil pump, based on target pressure indicated by a change command of the transmission state of the clutch unit and the hydraulic pressure measured by the pressure measurement unit.
