Problems solved by technology

In practical applications, the coaxiality between the left and right parts of the split housing and between the two parts and the gear is not easy to grasp due to assembly errors, prolonging the assembly cycle and reducing work efficiency; at the same time, even if the assembly is guaranteed Coaxiality, after long-term operation, there will still be coaxiality deviations in the external environment and operating factors. Due to the problem of coaxiality, frictional energy consumption is high and driving energy is wasted

Abstract

The invention discloses an electric tricycle driving assembly. The electric tricycle driving assembly comprises a power motor, a transmission and a differential, wherein the differential comprises a differential shell and a differential gear assembly; and the differential shell is of an integral structure. The electric tricycle driving assembly adopts a geared transmission system, the differential shell is of the integral structure, and relatively high coaxiality is determined during processing, so that the coaxiality is easy to guarantee in the mounting process, the electric tricycle drivingassembly can be directly mounted, and the mounting efficiency is improved; due to the integral structure, a coaxiality problem is not caused after long-term use and no eccentric wear between kinematic pairs is caused, so that prolonging of the service lives of the differential and a whole speed reducer is facilitated and the using cost is reduced; and due to no existence of the eccentric wear, the using energy consumption is greatly reduced, and thus increase in the mileage of a charged electric vehicle is facilitated.

Description

technical field [0001] The invention relates to a motor vehicle component, in particular to an electric tricycle drive assembly. Background technique [0002] Electric vehicles (two-wheel, three-wheel and electric vehicles) are powered by on-board power batteries to drive electric vehicles. Because electric vehicles have the characteristics of energy saving, environmental protection, lightness, and low cost of use, more and more attention has been paid to them. [0003] Due to the compact structure, convenient use and low cost of use, electric vehicles are mostly used in rural areas, towns and towns for transporting goods and personnel; due to the above characteristics of electric vehicles, the transmission of electric vehicles generally does not use gear shifting. The speed of the vehicle is directly controlled by adjusting the motor speed; for the uphill section with a large output torque, the existing single transmission structure can only increase the power output to ach...
