Because right tumbler gear 42, steering direction was opposite when right-hand track chiain driven wheel 48 was advanced with machine, and the drive path transferring power of left track during still according to above-mentioned straight forward; And the left and right number of teeth of driven wheel 35,31 that turns to equates that with the number of teeth of II retaining driven gear 33 left and right steering cluth gear 37,41 equates with the number of teeth of central driver gear 39.Therefore the right side crawler belt will be realized the combine pivot stud with identical theoretical velocity antiport with left track.
Flicker is identical with it to principle.
Five, pace conversion:
Driven wheel 25 often meshes with the running part driven wheel 27 that is fixed on the secondary variable-speed shaft 3, and therefore secondary variable-speed shaft 3 is in normal operating condition.
When hanging the I retaining, mobile I retaining driving gear 30 makes it and 34 engagements of I retaining driven gear, thereby makes driven variable-speed shaft 4 runnings, and power is passed to central driver gear 39 through I retaining driven gear 34 and II retaining driven gear 33.
When hanging the II retaining, mobile II retaining driving gear 29 and 33 engagements of II retaining driven gear, power is passed to central driver gear 39 through II retaining driven gear 33, as shown in Figure 1.
When hanging the III retaining, mobile II retaining driving gear 29 makes attached internal gear thereon and the pinion that is attached to III retaining driving gear 28, and power passes to central driver gear 39 through III retaining driven gear 32 through II retaining driven gear 33.
Six, stopping brake:
When combine stops operation or stops in the hillside fields, implement braking by brake activation device 23.
