FIELD: automotive industry.
SUBSTANCE: invention can be used in differential drives of wheeled vehicles made for automatic locking of wheels. Proposed self-locking differential of vehicle contains drive case 1 accommodating axle shaft-members 4, 5 arranged coaxially to each other and coupled with axle-shafts 2, 3. Said axle-shaft members are provided with helical grooves 6, 7 on outer surface with opposite hand of helix, solids of revolution in form of balls 8 filling in line at least one closed channel 10 made in drive case. Part of said channel is opened to dip segments of balls into helical grooves. Closed channel 10 is made rectangular in longitudinal section, with rounded off outer angles 12. Cross section of legs of rectangular closed channel is equal to diameter of balls 8. Number of balls in channel is odd.
EFFECT: simplified design of differential, reduced overall dimensions, increased manufacturability, strength and efficiency at self-locking.
