Problems solved by technology
[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 the power output to achieve the purpose of climbing, which will cause a lot of waste of power. Moreover, since the structure of the transmission is more concerned with driving on flat ground, the effect of increasing the power output for climbing is not ideal, and sometimes even the phenomenon of motor stalling occurs
[0004] Especially for small electric three-wheeled motorcycles, due to their own advantages of compact structure and light weight, if the existing geared transmission is directly used for this vehicle, it will increase the weight and volume, which cannot reflect energy consumption The economy, that is, can not solve the above problems

The invention discloses a speed change driving assembly of an electric tricycle. The speed change driving assembly of an electric tricycle comprises a power motor and a speed changer, wherein the speed changer is a two-gear speed changer; two-gear structure is adopted by the speed changer, so that the power output of the electric tricycle is reasonably allocated when the electric tricycle runs onflat roads and climbs; a reasonable shaft and gear arrangement is adopted with no increasing or reducing the size and the weight of the electric tricycle, so that electric tricycle has good energy consumption economy after checking, and the speed changer is suitable for the existing small electric tricycle; and power consumption during climbing is reduced, motor power is fully utilized during running on the flat roads, energy conservation and environmental protection are achieved, and use cost is reduced.
Description
technical field [0001] The invention relates to a motor vehicle component, in particular to an electric tricycle variable speed drive assembly. Background technique [0002] Electric vehicles (two-wheel, three-wheel and electric vehicles) are powered by vehicle-mounted power batteries to drive electric vehicles. Because electric vehicles have the characteristics of energy saving, environmental protection, portability, and low operating costs, 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 c...
