Document Type and Number:
Japanese Patent JP2020002974
Kind Code:
A
Abstract:
To provide a gear change device which can switch the engagement and release of the gear engagement of left and right power transmission mechanisms by using left and right common mechanisms, and can favorably achieve the gear engagement.SOLUTION: A power transmission route for transmitting power to left and right traveling devices is formed by the engagement of intermediate gears 112L, 112R and shifter gears 115L, 115R. The engagement of the intermediate gears 112L, 112R and the shifter gears 115L, 115R is released by the movement of the shifter gears 115L, 115R to a right direction from the formation state, and there arises a neutral state that the power is not transmitted to the left and right traveling devices. Shift forks 123L, 123R are connected to the shifter gears 115L, 115R. A shift fork shaft 121 for supporting the shift forks 123L, 123R is arranged so as to be movable to a rotation axial line direction, and energized to a left direction by a spring 129.SELECTED DRAWING: Figure 3
