Abstract

PURPOSE: To prevent sticking of clutch, by using hydraulic oil to be unnecessary at the neutral position of hydraulic cluch.
CONSTITUTION: Since oil passage 30e provided in the orifice of spool 30 meets oil passage e5 from pump 28, and other oil passage e1We4 of valve hole 29a connected to respective hydraulic clutch are to separate from oil passage e5 from pump 28 when speed change lever 31 is shifted to the neutral position, hydraulic clutch type change gear 21 becomes to the neutral position, and simultaneously oil passage 30e is connected to oil passage e5 through orifice 30a. Therefore, hydraulic oil of pump 28 reaches oil passage 30e and orifice 30a from e5, reaching the back of turn lock piston 34 from oil passage e5, thereby, since turn lock piston 34 is pushed to clutch housing 22, uncontrolled motion of clutch shaft 4 is prevented.
