METHOD TO CONTROL SLIPPING OF VEHICLE DRIVING WHEELS AND DEVICE TO LOCK VEHICLE DIFFERENTIAL Russian patent published in 2007 - IPC B60K17/35 B60K17/16 F16H48/26 

FIELD: transport engineering.

SUBSTANCE: invention relates to vehicle transmission and brake system control mechanisms. According to proposed method of driving wheel slip control, center differential is locked by acting onto brakes of driving wheels and (or) changing engine torque at moment of beginning of decreasing of torque transmitted to slipping wheels accompanied by reduction of wheel rolling radius. For this purpose, differential locking device contains hydraulic lock clutch, brush unit 5, high voltage unit 6 and control system including control unit 7 and angular velocity pickup 8, torque pickup 9, linear speed pickup 10 and steering wheel turning angle pickup 11 interconnected by electric circuits. Electrorheologic liquid is used as working liquid. Clutch members are isolated from each other.

EFFECT: improved efficiency of driving wheel slipping control and operation of differential locking control system.
