Abstract
A front-drive and rear-drive transfer case of a tractor comprises a power input shaft 1, a change gear 4 with a shift fork groove, a shift fork 6, a rear-drive output shaft 9, a rear-drive output gear 5, a front-drive transition gear 3, a gap bridge shaft 11 and a gap bridge gear 10. The left end of the front-drive and rear-drive transfer case is provided with a front-drive output shaft 13 of a bevel gear, a front-drive output gear 12 and a box body 7. The change gear 4 is poked through the shift fork 6 so as to choose driving force. When the change gear 4 is meshed with the front-drive output gear 12, front drive is adopted by the tractor; when the change gear 4 is meshed with the rear-drive output gear 5, rear drive is adopted by the tractor; and when the change gear 4 is meshed with the front-drive output gear 12 and the rear-drive output gear 5 simultaneously, front drive and rear drive are adopted by the tractor. The front-drive and rear-drive transfer case can select an appropriate operation driving force according to different road condition operation requirements, improves integral performance and applicability of the tractor and has the advantages of being simple and compact in structure, small in noise, high in transmission efficiency and low in fabricating cost.
