Abstract

The invention provides a diameter-variable multi-gear combined equivalent gear drive type continuously variable transmission, and discloses a gear continuously variable transmission. According to thegear continuously variable transmission, a plurality of gears are combined to form an equivalent gear for transmitting rotating mechanical energy, and the transmission is applicable to electric cars.The diameter-variable multi-gear combined equivalent gear drive type continuously variable transmission comprises a driving gear assembly and a driven gear assembly, wherein the last-grade gear, engaged with the driven gear assembly, of the driving gear assembly is the multi-gear-combined type equivalent gear; the primary gear, engaged with the driving gear assembly, of the driven gear assembly isthe multi-gear-column combined type equivalent gear; the two equivalent gears are engaged to transmit the rotating mechanical energy, and synchronous transmission in the engaging state is achieved. The diameter-variable multi-gear combined equivalent gear drive type continuously variable transmission has the advantages that the radius of the plurality of gears [or gear columns] is smoothly changed without any grade and in a balancing manner; the plurality of radius-changed gears [or gear columns] are capable of naturally smoothly changing the rotation transmitting speed without grade and in abalancing manner. Therefore, the rotating power is transmitted through the gears.

Description

technical field [0001] The invention discloses a gear-driven continuously variable transmission, in particular to a gear continuously variable transmission which can be used for electric vehicles in which a plurality of gears are combined to transmit rotational mechanical energy equivalent to one gear. Background technique [0002] Electric vehicles are the future development trend of automobiles. The current electric vehicles are basically not equipped with transmissions. They mainly use the adjustment of current and voltage to achieve variable speed. The reason is that there is no transmission product suitable for high speed and efficiency of electric vehicles. CVT Continuously variable transmission is recognized as the most comfortable ride, simple driving, and good energy-saving performance. However, the poor manufacturability of the friction transmission of the cvt continuously variable transmission is a fatal shortcoming, and it cannot be used for electric vehicle tran...
