WIPO Patent Application WO/2016/060025
Kind Code:
A1
Abstract:
To enable the structure of a rear axle case to be shared between a design having tread variations and a design having no tread variations in a work vehicle such as a tractor. Rear axle cases (19) provided to the left and right sides of a transmission case (17) are configured from a secure-side case (771) linked to the transmission case (17), and a sliding-side case (772) fitted into the secure-side case (771) so as to be capable of sliding left and right. The tread between left and right rear travel parts (4) provided to the left and right sliding-side cases (772) are configured to be variable. Also provided are tread-adjusting hydraulic cylinders (645) for sliding the sliding-side cases (772) to the left and right, and locking cylinders (781) for inhibiting the co-rotation of the sliding-side cases (772) interconnected with the rear travel parts (4). The tread-adjusting hydraulic cylinders (645) and the locking cylinders (781) are detachably attached so as to be distributed forward and rearward of the rear axle cases (19).
