Abstract

PURPOSE:To reduce the breadth of a speed change steering system by arranging a train consisting of a one (1) speed, F2, F3, R2 and R3 clutches and the first to fourth planetary gear trains to respective shafts. CONSTITUTION:A clutch out of one (1) speed clutch 14 selectively fixing a three (3) speed gear 23, F2 clutch 15 selectively connecting a two (2) speed gear 25 to a countershaft 20, F3 clutch 16 selectively connecting the three (3) speed gear 23 to the countershaft 20 or R3 clutch 18 selectively fixing the ring gear 12r of a three (3) speed planetary gearing 12 is engaged. This engagement makes it possible to expand a car speed range in both forward movement and backward movement. In addition these clutches 14-18 are arranged to the countershaft 20, and the first to fourth planetary gearings 8-10 are provided to a main spindle 19. Such arrangement makes it possible to obtain a speed change steering system suitable for bulldozers and reduced the breadth.
