Hydraulic unit and control method of hydraulic unit

Abstract

To provide a hydraulic unit of a speed change control device which can simplify a structure of a hydraulic mechanism which hydraulically controls a clutch actuator and a shift actuator of a speed change control system, and can attach the device even in a small space.SOLUTION: In a hydraulic unit (200) for driving a clutch actuator (26) for connecting and disconnecting a shift clutch when performing the switching of a speed change gear of a multistage shift mechanism, and a shift actuator (27) for changing a position of the speed change gear according to an input command of a shift position, a valve for hydraulically controlling the clutch actuator and the shift actuator, a pump and a motor for driving the motor are integrally formed.SELECTED DRAWING: Figure 2
