Document Type and Number:
Japanese Patent JPS5846247
Kind Code:
A
Abstract:
PURPOSE:To obtain an accurate operation manner and a simple structure by controlling an electromagnetic valve group controlling a plurality of fluid type clutch actuators and the like by a manipulation signal from a control circuit supplied with a position signal of a shift lever, a vehicle speed signal and an engine load signal. CONSTITUTION:The supply of oil pressure to first and second actuators 8 and 12 for actuating a first clutch 5 and a second clutch 6 is controlled by means of first and second electromagnetic valves 60 and 61. The first and second electromagnetic valves 60 and 61 are connected to a pressure line 34a connected to actuators 8 and 10 through passages 65 and 66, on another. The supply of oil pressure to first and second speed change cylinders 20 and 23 is controlled by the first and second speed change electromagnetic valves 63 and 64. Each of electromagnetic valves is controlled by a control signal of the control circuit 53 supplied with a signal S1 from the shift lever L, a vehicle speed sensor signal S3 and an engine load sensor signal S2.
