Abstract

The invention provides a variable-diameter gear continuously variable transmission. The transmission is composed of a variable-speed stage and an amplifying stage, wherein the variable-speed stage is a variable-diameter inner gear ring composed of a variable-diameter inner gear ring composed of a plurality of gear lobes, three variable-diameter planetary gear sets and an output sun gear; the amplification stage is a standard fixed transmission ratio planetary gear transmission, and a continuously varying variable ratio of the variable-speed stage is amplified by an appropriate amplification factor as required, an arbitrary speed regulation range can be combined not only through different amplification factors of the amplifying stage but also can be combined through different input rotational speeds, for example, according to the principled sample machine manufactured by a company, the variable ratio of the amplification stage is 5.5 times, an input rotational speed is 3000 revolutions / minute, and therefore the output rotational speed of an output shaft varies continuously from reverse 1600 revolutions / minute to forward 5200 revolutions / minute; due to the fact that the output rotational speed can approach to zero, so that the torque can approach to infinitely great, the significance of the characteristic is very important, and the revolutionary change of a whole industry can be brought.

Description

technical field [0001] The invention relates to a variable-diameter gear continuously variable transmission, which belongs to the technical fields of machinery manufacturing and automobile manufacturing. Background technique [0002] Anyone who knows cars knows that the speed of the car engine has the most economical and efficient speed range. In this speed range, the fuel consumption is the lowest and the torque is the highest. The function of the transmission is to ensure that the car can run at different speeds while keeping the engine speed at an efficient speed as much as possible. For example, the optimal speed range of most engines is between 2000 rpm and 4000 rpm, but cars need to run at different speeds. In order to change the speed of the car while maintaining the optimal speed of the engine, people began to use The mechanical transmission is used to change the speed of the output shaft to meet the needs of road conditions and driving speed. But, the speed change...
