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

Embodiment Construction

[0021] figure 1 It is a schematic diagram of the structure of the present invention, as shown in the figure: the electric tricycle transmission system of this embodiment includes a transmission, and a differential housing is arranged in cooperation with the power output end of the transmission, and the differential housing is an integral structure.

[0022] As shown in the figure, the power input of the transmission passes through a power motor 22 and through a gear assembly arranged in the differential case 1. The gear assembly includes a planetary gear 5 and a left side shaft gear 2 according to the structure of the prior art. and the right side shaft gear 4, which will not be described in detail here; the differential housing 1 is provided with installation through holes for installing the gear assembly; the transmission housing 1 of the integral structure needs to be provided with installation through holes on the side, Or adopt integral frame structure, be used to install...

Abstract

The invention discloses an electric tricycle transmission system. The electric tricycle transmission system comprises a transmission; a differential shell is arranged and is in transmission match witha power output end of the transmission; the differential shell is of an integral structure; a shift differential system is adopted; the differential shell is of the integral structure, so that bettercoaxiality can be determined during machining, so that coaxiality is ensured during the assembly process; assembly can be performed directly; assembly efficiency is improved; the integral structureis adopted, so that the coaxiality problem does not occur after long-time use; eccentric wear cannot happen between motion pairs; the service lives of the differential and a whole reducer are favorably prolonged; the using cost is lowered; the using energy consumption is greatly lowered since the eccentric abrasion does not exist; and the travel distance after charging of an electric tricycle is favorably increased.

Description

technical field [0001] The invention relates to a motor vehicle component, in particular to a transmission system of an electric tricycle. 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 its compact structure, convenient use and low cost of use, electric tricycles are mostly used in rural areas, towns and towns for transporting goods and personnel; due to the above-mentioned characteristics of electric tricycles, 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 t...
