An automatic gear-shifting differential mechanism consists of a speed change box, a driving gear, large and small transmission gears, an overrunning clutch gear set, a differential mechanism gear, a steel plate spring, a power motor, a gear-shifting motor and an intelligent controller, wherein the overrunning clutch gear set is provided with left and right clutching saw-shaped teeth and left and right saw-shaped teeth. The automatic gear-shifting differential mechanism adopts a mechanical overrunning clutch scheme, the synchronization requirement for the rotation speed of the gear set is not high, simple pulse speed regulation and fuzzy control are adopted, the reliability is improved, complicated control hardware and software are omitted, elastic drive of the overrunning clutch gear set makes the clutching saw-shaped teeth small in noise and low in noise, tooth-clamping, tooth-bumping, stuck and out-of-control phenomena do not occur, their reliable impact-free meshing can be ensured only by controlling the rotation speed of the clutching saw-shaped teeth to be greater than the rotation speed of the saw-shaped teeth in a certain range, and the gear-shifting time is very short. Theintelligent controller automatically controls the gear-shifting motor to perform high and low gear shifting according to the load and rotation speed of a power motor, a low-speed gear is adopted during starting, high-speed gear is adopted during normal speed, the low-speed gear is adopted during climbing, and the problem of mechanism damage caused by manual improper operation is effectively solved.
Description
technical field [0001] The invention relates to a differential motor of an electric tricycle, to be precise, an automatic shifting differential. Background technique [0002] At present, with the change of market demand, the differential motor of the electric tricycle has experienced the process of continuous progress and development from the initial constant gear shift to manual shift gear, and from manual shift gear to automatic shift gear. For the technological innovation of gear differential, there is an application number "2015104435079" which is an invention patent of "automatic gear shifting motor". It is an ideal gear shifting method, but its automatic gear shifting differential has the disadvantages of complex structure and high cost. Contents of the invention [0003] In order to overcome the deficiencies of the existing automatic shifting motor, the present invention introduces an automatic shifting differential, which can not only automatically shift between h...
