PURPOSE:To obtain compact structure by installing a brake apparatus and a differential locking apparatus into the space part on the both sides of the partitioning wall in a front axle housing, arranged in parallel to a differential gear installed in the center space part in the front axle housing. CONSTITUTION:Among the differential side gears 5 and 5 of a differential gear 4 installed into the center space of the front axle housing 3 of a tractor, the shaft cylinder part 7 of the gear 5 on a ring gear 6 side is inserted into the hole part 9 of the cylindrical boss part 8 of a rng gear 6, and a clutch part 11 is formed onto the edge part of a projection part 10 which projects from the edge part of the shaft cylinder part 7. The center bearing part 12 is fitted onto the projection part 10, and a housing 16 is formed from a partitioning wall 13 extended in the radial direction onto the bearing part 12 and an outer peripheral wall 15 supported onto the cylindrical boss part 8 through a bearing 14. In the housing 16, a power brake apparatus 17 and a power differential lock apparatus 18 are arranged in the space part between the both sides of the partitioning wall 13. |
