Abstract

PURPOSE: To perform shifting operation by simple structure, by utilizing a motor for producing hydraulic pressure.
CONSTITUTION: A rotary shaft 7 of the motor 1 is connected to a driving shaft 8 of a hydraulic pump 6 through a coupling 9. The hydraulic pump 6 is rotatably supported on a bearing mechanism 5 in a cylinder 4. A hydraulic duct 15 is secured to the body of the hydraulic pump 6 and has its front end coupled to a fixed member 16 wherein a hydranlic duct 17 from a negative brake is connected to an unloading hydraulic duct 18 from an oil tank. When the motor 1 is driven, the driving shaft 8 rotates to produce hydraulic pressure. Then, the body of the hydraulic pump 6 rotates against a restoring spring and the front end of the hydraulic duct 15 swings to the position (b) to transmit the hydraulic pressure to the negative brake
