FORCED LOCKING DIFFERENTIAL OF A LEADING VEHICLE BRIDGE Russian patent published in 2018 - IPC F16H48/30 

FIELD: vehicles.

SUBSTANCE: invention relates to a system with forcibly blocked differential mechanisms. Device consists of four components: a conical differential, a differential lock, a mechanism for longitudinal movement of the differential lock and a drive mechanism for longitudinal movement. Differential has housing (1) with two process windows (2) designed for the installation of spur bevel gears (3) and spur gears (4) that rotate freely on axis (7). Differential lock consists of locking clutch (8), on its inner surface two cylindrical blocking sectors (9) are fixed . On the inner surface of sectors there are ribs (10) of rectangular cross-section of the axial direction, pushers (14) with springs (13) are installed in the longitudinal channels of the blocking sectors. Semi-axial gear (3) located on the side of driven gear (6), has grooves of rectangular cross-section in the axial direction between the gear teeth. Mechanism for the longitudinal movement of the differential lock consists of squeeze bearing (18), movably fixed to clutch release fork (17) movably fixed to body of the longitudinal movement mechanism (15), rocker (16). Drive mechanism of the longitudinal movement consists of drive cable (24), rod (23), bushing (21), return spring (22), damper spring (20), shift lever (19), limit switch (25) and indicator light (26).

EFFECT: increase in the off-road properties of the vehicle is achieved.
