Apparatus for transferring power having a motor

Abstract

The invention provides an transmission mechanism having a motor, characterized in that, including: a plurality of motors, joined with the exterior face of a cover, and acted by the power supply of a power supply part; drive gears, respectively joined with the bottom terminals of electromotor shafts in the cover, rotated by the rotary movement of the electromotor shafts; a driven gear, having a dimension ratio more than the predetermined ratio relative to the drive gear, engaged with the drive gear, rotated by the rotary movement of the drive gear; a speed-variator, mounted between the driven gear shaft and the drive shaft, forming a number of steps of speeds by rotating the drive shaft, as an output shaft, in the predetermined ratio rotated relative to the driven gear shaft, as an input shaft; and a control part, for controlling the number of steps of speeds of the speed-variator. The electric vehicle can be drived efficiently even if low-power supply source is used, because the mechanism is able to produce a power source having high output torque, and to provide the desired power efficiently.

Description

Technical field [0001] The present invention relates to a transmission device with an electric motor, and in particular to a transmission device with an electric motor, that is, because it is constructed with a power source capable of generating a high output torque and efficiently provides the required power, even if a low power is used The supply source can also efficiently drive electric vehicles such as hydraulic equipment, cranes, and golf carts. Background technique [0002] In the past, electric vehicles such as golf carts have been equipped with a high-output DC motor as a power source for the electric vehicle in order to run smoothly even in a high-output operating environment required when starting or going uphill. However, because high-output DC motors are not easy to buy in China, they need to rely on imports, which makes the purchase cost and maintenance cost a great burden, and due to excessive battery consumption, large-capacity batteries must be used. And because ...

AI Technical Summary

Problems solved by technology

However, since high-output DC motors are not easily available domestically, they need to rely on imports, which imposes a heavy burden on purchase and maintenance costs, and must use large-capacity batteries due to excessive battery consumption.

And because large-capacity batteries are also imported products that are not easy to buy, the purchase cost becomes higher

Battery consumption is further exacerbated by large batteries that increase the weight of electric vehicles

[0003] In addition, since a high-output DC motor is installed in consideration of an operating environment in which the running time such as starting up or going uphill is short and requires high output, there are cases where, although most of the running time is High output is not required when driving on flat ground, so-called energy inefficient consumption consumes unnecessary power and wastes batteries
