LATCHING DIFFERENTIAL OF A WHEEL TRANSPORT CARRIER Russian patent published in 2005 - IPC

FIELD: the invention refers to transport machinery.

SUBSTANCE: latching differential has a differential gear 4, a blocker and a control device. The control device has a scheme of measuring and comparison and sensors of a wheels angular speed in the shape of tachometers 11 and 12, kinematically connected with half-axles 9 and 10. The scheme of measuring and comparison includes differential links 13 and 14 and summing units 15 and 16 of angular accelerations, and an electro-chain of connection to a servo-motor 22 has intensifiers 19 and 20 and a relay of time 21. Differential links 13 and 14 are electrically connected with the sensors of wheels angular speeds. The differential realizes automatic blocking only at skidding of any driving wheel and does not react to other exterior disturbing influences. The control device works on the principle of comparison of an angular speeding up of a skidding wheel with given critical meaning equal to maximum possible speeding up at which skidding is still impossible.

EFFECT: decreasing of dynamic loads on transmission and drive and increasing reliability and longevity of a vehicle.
