Title:
CONTINUOUSLY VARIABLE TRANSMISSION POWERTRAIN
Document Type and Number:
WIPO Patent Application WO/2023/043157
Kind Code:
A1
Abstract:
The present invention relates to a continuously variable transmission powertrain having a transmission unit and motors integrally configured, wherein the transmission unit is configured as a multi-speed transmission gear device, motors are configured at respective input and output sides of the transmission unit, the input-side motor drives a first transmission gear device, the first transmission gear device drives a second transmission gear device again, thereby enabling deceleration, and thus an impact does not occur during transmission, and transmission is enabled by controlling the rotation of the second transmission gear device by means of the output-side motor. According to the continuously variable transmission powertrain, according to the present invention, continuously variable gear ratios are provided so as to continuously induce maximum motor efficiency, and thus maximum hill-climbing ability and maximum speed performance required for an electric vehicle may be satisfied, and the structure is simple without a complicated hydraulic device, and high power transmission efficiency is implemented by means of a light weight, and thus fuel economy may be improved, and energy is not consumed in the transmission, and transmission may be smoothly carried out.
