Continuously-variable transmission

Abstract

The invention provides a method and device for realizing stepless variable speed. The structure of the device is shown as the figure attached: a planet wheel 2 and a planet wheel 4 are fixed on a shaft 6 to form a whole structure which is installed on a planet carrier, the planet wheels can rotate around the shaft 6, and the whole structure can rotate around a shaft 5. When the whole structure is under moment balance, if an input power or resistance changes, the moment balance is broken, then powers obtained in the rotation directions of the planet wheel 2 and the planet wheel 4 around the shaft 6 and the shaft 5 can be newly distributed to reach a new moment balance, thereby realizing the stepless variable speed. The device can realize the stepless variable speed without being monitored by a computer, and has low requirements on processing material and technology.

Description

technical field [0001] The invention relates to a method and device for autonomously and automatically realizing stepless speed change. Background technique [0002] Although the traditional continuously variable transmission can realize the function of continuously variable speed, the existing problems are so obvious that although the continuously variable transmission has the incomparable advantages of ordinary transmissions, in the transmission market, ordinary transmissions still occupy more than half of the country. Traditional continuously variable transmissions exist The following problems: One, it cannot withstand large loads, so it has been used in small displacement and low power vehicles. Second, the computer needs to monitor the input power and the change of the resistance of the output end, and then change the transmission ratio to achieve the purpose of continuously variable speed. Third, the requirements for materials and technology are high. Four, transmiss...

Problems solved by technology

[0002] Although the traditional continuously variable transmission can realize the function of continuously variable speed, the existing problems are so obvious that although the continuously variable transmission has the incomparable advantages of ordinary transmissions, in the transmission market, ordinary transmissions still occupy more than half of the country. Traditional continuously variable transmissions exist The following problems: 1. It cannot withstand large loads, so it has been used in small displacement and low power vehicles.

3. High requirements on materials and technology

Fourth, the transmission efficiency is low

All of these will increase the manufacturing cost and manufacturing difficulty, making it difficult for the continuously variable transmission to be widely recognized
