Title:
STEERING SYSTEM FOR WALKING FARM WORKING MACHINE
Document Type and Number:
Japanese Patent JPH02286471
Kind Code:
A
Abstract:

PURPOSE: To reduce a turning radius by shifting a shift sleeve at time of sudden turning, and engaging an axle with a transmission case with the disengagement of a side clutch of a travel device at the turning inside, while operating a side brake.

CONSTITUTION: In symmetrical transmission shafts 7 driving symmetrical running wheels separately, there is provided a ball-type side clutch 8 to interrupt power. In this case, each cylindrical member 12 being externally fitted in the transmission shafts 7 is clamped to the inner part of a transmission case 1, and a recess 7a and a hole 12a being opposed with each other are formed in these members. Then, a brake ball 13, where any displacement in the radial direction to the transmission shafts 7 is allowed or checked by a single shift sleeve 11 allowing and checking any radial displacement of a clutch ball 10 in the side clutch 8, is set up in the hole 12a, constituting a side brake 14. In brief, the transmission shaft 7 and the cylindrical member 12 are engaged with each other with the shift of the shift sleeve 11, and the side brake is operated.
