Abstract

PURPOSE: To operate a device efficiently, by making it possible to operate mechanical speed change and hydraulic clutch type speed change without exchange of a shifter fork by one operation lever, in the forward and backward multistage variable speed gear used in the power-driven work car for civil engineering and agriculture or the like.
CONSTITUTION: In case of forward movement of the machine body, an operation lever 1 is turned in a prescribed direction and is inserted into a groove 4, and transmission shafts 26 and 26' are interclocked with this operation to turn an arm 28 while turning, and thus, front and rear wheels are rotated forward, and the speed changing operation from forward one speed to three speed is performed under the state where the operation lever 1 is inserted from a neutral groove 2 to respective grooves 4, 4' and 4". In case of backward movement of the machine body, the operation lever 1 is turned from the neutral groove 2 in a direction opposite to the prescribed direction and is inserted into end parts 4R, 4'R and 4"R of the speed changing grooves 4, 4' and 4", and the speed changing operation from backward one speed to three speeds is performed by the reverse turning operation. As a result, speed change is operated without exchange of the shifter fork by one operation lever to prevent accidents such as double entanglement and facilitate maintenance.
