Electric automatic differential lock

Abstract

The invention discloses an electric automatic differential lock comprising a differential lock large shell, a differential lock small shell nested at one end of the differential lock large shell, and a planet gear. The planet gear mounted between the differential lock large shell and the differential lock small shell is fixed through a cross shaft. Each of the differential lock large shell and the differential lock small shell is provided with an axle shaft gear inside. Both the axle shaft gears mesh with the planet gear. Each axle shaft gear is provided with a plurality of generator permanent magnets with alternately arranged positive and negative poles inside. A generator core and a generator coil are sleeved outside the axle shaft gears. An electromagnet coil and a friction plate are disposed in each of the differential lock large shell and the differential lock small shell. Regulating springs and screws are disposed between each electromagnet coil and one of the differential lock large shell and the differential lock small shell. Each of the differential lock large shell and the differential lock small shell is provided with a speed-limiting eccentric switch. Through the structure, the problem that an automobile idles due to skidding of a single wheel is solved, and the automobile can be freed of the dangerous situation and driven normally. The electric automatic differential lock has the advantages of simple structure, convenience in use and operation, low failure rate, high stability and convenience in popularization.

Description

technical field [0001] The invention relates to the field of automobile drive trains, in particular to an electric automatic differential lock for automobiles. Background technique [0002] The differential is mainly used to balance the speed difference between the inner and outer wheels when the vehicle is turning, so that the vehicle can turn smoothly without consuming too much energy. It is precisely because of the differential principle of the differential and the effect of equal torque that when the vehicle is driving In bad road conditions, the wheels often fall into the mud, sand or ice and snow roads, causing a wheel to slip or even hang in the air, so that the vehicle is trapped and unable to extricate itself. In this case, the driver usually thinks of padding under the slipping wheel Hard objects such as stones to increase the adhesion of the wheels, but this method is often self-defeating, making the wheels sink deeper and deeper. [0003] At present, the solutio...
