HYDRAULIC CONTROL DEVICE OF AUTOMATIC SPEED CHANGE GEAR
Document Type and Number:
Japanese Patent JPS6040855
Kind Code:
A
Abstract:
PURPOSE:To simplify a control device and to improve responsibility of the device by assembling a shift valve with a solenoid valve for operating and controlling the shift valve, and electrically controlling the solenoid valve to switch a main path. CONSTITUTION:The first to fifth shift valves 21-25 in a shift valve device 20 are disposed in branch paths 14-17 forming a main path 10. These first to fifth shift valves are assembled with solenoid valves 31, 32, 33 for operating and controlling the shift valves 21-25, and the solenoid valves 31, 32, 33 are controlled to switch the main path 10 to a clutch element and a brake element. Thus, a position is electrically selected, and the setting of its operation part can be freely performed, so that a control device can be simplified and the responsibility of a speed change switch to a change in car velocity can be improved.
