The worm and worm mechanism in the

The worm and worm mechanism in the differential will self lock. Thomson differential is a fully mechanical device without actuator, clutch, sensor and hydraulic system. The worm gear of Thomson differential not only meshes with the worm on the axle shaft, but also the two ends of the worm gear mesh with each other. The characteristic of this connection mode makes Thomson differential mechanism work like ordinary differential mechanism under the condition of uniform torque;
