Title:
REAR WHEEL DRIVING DEVICE OF WORKING VEHICLE
Document Type and Number:
Japanese Patent JP3921170
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a compact working vehicle for compactly constituting the final speed reduction mechanism, and having a narrow tread by strengthening a gear by improving tooth contact of the gear in the final speed reduction mechanism.
SOLUTION: This working vehicle transmits motive power from an engine 6 via a transmission, a differential device 14 and the final speed reduction mechanism 20. The final speed reduction mechanism 20 is arranged in the rim 32 of a rear wheel 2, and the final speed reduction mechanism 20 is composed of the final pinion gear 21 fixed to a drive shaft 51 connected to the output side of a transmission case 9 and an internal gear 22 fixed to a wheel shaft 23 and having a ring-shaped groove 22a on an inner side surface. A bearing 91 is arranged in an end part of a drive shaft 23 on the outside of the final pinion gear 21, and the bearing 91 is inserted into the groove 22a.
