Transmission mechanism used for electric vehicle

Abstract

The invention provides a transmission mechanism used for an electric vehicle. The transmission mechanism comprises a power device and a speed reducer. The power device is connected with the speed reducer. The two sides of the speed reducer are connected with transmission components. Each transmission component comprises a transmission shaft, a tower footing assembly and a hub. The two transmissionshafts are inserted in the two sides of the speed reducer. The tower footing assemblies and the hubs are arranged on the transmission shafts. The tower footing assemblies are arranged between a transmission and the hubs. Each tower footing assembly comprises a first tower footing, a second tower footing and a third tower footing. The transmission shafts are inserted in the first tower footings. Multiple ratchet annular groove parts are arranged in the circumferential direction of each first tower footing and connected with ratchet blocks. Ratchet grooves are formed in the second tower footings. The first tower footings and the second tower footings are connected through engagement of the ratchet blocks and the ratchet grooves. The second tower footings are inserted in the third tower footings. The third tower footings are connected with the hubs through couplers.
