ABSTRACT:
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.
