VEHICLE MECHANICAL TRANSMISSION (4×4) WITH A CROSS-AXLE VARIABLE DIFFERENTIAL MECHANISM AND A SYSTEM FOR AUTOMATIC CONTROL OF DIFFERENTIAL OPERATION MODES DURING NON-LINEAR MOTION Russian patent published in 2021 - IPC F16H48/30 B60K17/348 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to a mechanical transmission with a hydraulically controlled mechanism for engaging the front drive and locking the center differential. The mechanical transmission with a front cross-axle differential (CAD) is equipped with a friction clutch with an adjustable hydraulic spring mechanism and a rear cross-axle differential mechanism (CADM) with an adjustable automatically controlled throttle regulator at the outlet and an overflow valve at the outlet of the hydraulic machine. The mechanical transmission also contains an ACS, which provides: at zero or small below a given threshold value of centripetal acceleration, stable movement of the vehicle due to the adjustable locking moment of the rear CADM non-rectilinear movement and due to the additional inclusion of the adjustable blocking of the front CAD - rectilinear movement; with a greater value of centripetal acceleration due to maintaining the specified optimal value of the vehicle steering criterion by stepless regulation of either a positive or negative difference in the rear wheel rpm, as well as adjustable locking moments of the rear CADM and front CAD with automatic engagement of the front drive and blocking of the MOD.

EFFECT: increased vehicle handling.
