Abstract
A transmission system for vehicle transmission mechanism (B) having a low speed hydraulic clutch (CL) and a high speed hydraulic clutch (CH) as a wet multi-disk clutch for transmission, wherein both the low speed hydraulic clutch (CL) and the high speed hydraulic clutch (CH) are disengaged so as to disconnect a transmission of an engine power to the transmission system, namely, so as to bring a main clutch into off condition, a dry clutch device (A) is installed on the upstream side of transmission of the transmission mechanism as a corotation prevention mechanism, only the low speed hydraulic clutch (CL) of large capacity is used as an inching clutch to bring the main clutch into a partial engaged condition when the main clutch is moved to on or off in the transmission mechanism (B) and, when the main clutch is operated from off to on with a shift lever ( ) set at a high speed position, hydraulic pressure control is performed so that the high speed hydraulic clutch (CH) is brought into off condition and the low speed hydraulic clutch (CL) is brought into the partial engaged condition in the off range (D ) and inching range (D ) of the main clutch, of a clutch pedal ( ), respectively.
