In a crawler drive transmission in which the inner ends of both cylindrical intermediate shafts are interlocked and connected to the input shaft via a gear transmission mechanism with a side clutch device so as to rotate at a constant speed. , a principle wheel 2 of a first transmission mechanism that rotates the corresponding output shaft 7 in the opposite direction to the cylindrical intermediate shaft 1 at the outer end of the cylindrical intermediate shaft 1 on both sides; A driving wheel 3 of a second transmission mechanism that rotates in the same direction as the shaft is mounted so as to be rotatable in a symmetrical arrangement, and the transmission ratios of the first and second transmission mechanisms are configured to be approximately equal, and each cylinder Between the shaped intermediate shaft and the driving wheels of the first and second transmission mechanisms, axial V grooves 2a and 3a are recessed evenly on the inner periphery of each driving wheel, and in each of the V grooves, respectively. A ball clutch including balls 8 and 9, some of which are permanently engaged with radial ball guide holes 1a and 1b correspondingly bored in the cylindrical intermediate shaft, is provided, and each ball is inserted into a corresponding V groove. 1 removable abacus-shaped guard 1
The control shaft 10 provided with the collar 0a is placed at a position where the collar faces the ball guide hole 1a of the ball clutch on the first transmission mechanism side and at a position where it faces the ball guide hole 1b of the ball clutch on the second transmission mechanism side. 1. A crawler drive transmission characterized in that the transmission is mounted within a cylindrical intermediate shaft so as to be selectively switched, and configured so that when one of the two ball clutches is engaged, the other is disengaged. 2. The first transmission mechanism is configured as a gear transmission type, and the second transmission mechanism is configured as a chain wheel transmission type. A crawler drive transmission according to claim 1, wherein a compression spring (11) is disposed and is mounted in a cylindrical intermediate shaft on the inner end side of the control shaft (10) for constantly urging the ball clutch of the transmission mechanism for moving the vehicle in a straight line into engagement. .
