摘要： A differential locking system of an axle driving apparatus wherein left and right axles are rotatably supported within a housing consisting of an upper half housing and a lower half housing. The inner ends of the axles are facing each other and are rotatably inserted within a differential input gear. An engaged plate member is disposed at the right of the differential input gear. Engaged recesses of the differential input gear and engaged recesses of the engaged plate member are connected with each other. A pair of differential pinions are pivoted within the differential input gear, perpendicular to the axles. Both sides of each differential pinion are engaged with differential side gears fixed around the right and left axles, respectively. Pin passing holes are bored in the right differential side gear. A thrust collar is disposed on the right axle outside of the right differential side gear. A shifter fixing the differential locking pins is axially slidably disposed around the thrust collar. The differential locking pins pass through the corresponding pin passing holes and can be inserted into and removed from engaged recesses of the differential input gear and the engaged plate member. A shift fork holds the shifter horizontally and rotatably engages at the upper end thereof with an upper half housing and at the lower end thereof with a lower half housing. A differential locking arm is attached to the bottom surface of the lower half housing so as to rotate the shift fork.

摘要： In a vehicle transmission comprising a hydrostatic transmission (13) and a rear-wheel drive assembly (20) including a two-stage speed change mechanism (28), a front-wheel drive assemly (22) having a front-wheel drive shaft (24) is disposed at a front side of the output shaft (17) and includes a clutch (55; 155; 255) such that when the change mechanism is shifted to its high-speed position the clutch is disengaged so as to provide a non-drive mode for front wheels. A selective drive mode is preferably provided by a one-way clutch (56) which is operable to connect the drive shaft to the output shaft only when forward directional rotation speed of the output shaft is larger than that of the drive shaft. In a preferred embodiment, the front-wheel drive assembly is shiftable at a low-speed position of the change mechanism between a constant drive mode and the selective drive mode. This drive assembly may also be fashioned such that it is shiftable at the low-speed condition between the constant or selective drive mode and non-drive mode.
