FORCIBLY LOCKED CONICAL DIFFERENTIAL OF VEHICLE (VERSIONS) Russian patent published in 2020 - IPC F16H48/32 

FIELD: machine building.

SUBSTANCE: group of inventions relates to differential transmissions. In the first version, differential has housing 1 with cover 2, in housing there are half-axes straight-run bevel gears 4 and 5, pair of satellites 6 interacting with them is installed between gears, axis 7 of which is fixed in housing 1. In the cover on the end surface facing the housing there is an annular groove forming open chamber 9, in which piston 10 is installed, which is in contact with the first gear, which is installed with possibility of its longitudinal movement towards side of semi-axial gears and power action on semi-axial gear 4 with provision of its movement towards gear wheel 5. Axis of satellites is installed in diametrically located O-shaped slots made in housing and oriented along axis of differential housing, with possibility of parallel shift of axis of satellites towards second half-axis gear 5. Chamber 9 is communicated via channel 11 made in cover with union 12 to feed working fluid. On annular side surfaces there are annular grooves accommodating O-rings. In second version 4 satellites are installed on the "floating" cross piece.

EFFECT: provides for simplified design and increased wear resistance of differential.
