Abstract

The invention discloses a continuously variable transmission which comprises an input shaft, a first high-speed rack, a high-speed shaft, a second high-speed rack, a low-speed rack set, a speed changing system, an output sun wheel and an output shaft. One end of the first high-speed rack is connected with the input shaft through a planet gear. The first high-speed rack can rotate under the drive of the input shaft. One end of the high-speed shaft is fixedly connected to the high-speed rack, the high-speed shaft can rotate under the drive of the high-speed rack, and a one-way bearing is arranged on the high-speed shaft. One end of the second high-speed rack is fixedly connected with the high-speed shaft, and the second high-speed rack can rotate under the drive of the high-speed shaft. The low-speed gear set comprises an input gear ring, a low-speed gear, a low-speed shaft, a low-speed auxiliary gear and an output gear ring. The speed changing system is engaged with the input gear ring. The output sun wheel is connected with the second high-speed rack and can rotate under the drive of the second high-speed rack. The continuously variable transmission is high in transmission efficiency, cannot skid and is simple in structure and smoother in the speed changing process.

Description

technical field [0001] The present invention relates to a transmission, more precisely a continuously variable transmission. Background technique [0002] Existing continuously variable transmission basically all is to change the diameter of driving wheel, driven wheel, realizes with the mode of friction transmission. This speed change mode enables the speed changer to realize speed change in a continuously variable manner. However, the biggest disadvantage of this transmission method is that it is easy to slip, the transmission efficiency is not high, and it cannot transmit large load power. [0003] The existing continuously variable transmission has the disadvantages of easy slipping, low transmission efficiency, complex structure and high cost because it is driven by friction. Contents of the invention [0004] The purpose of the present invention is to provide a continuously variable transmission, which can solve the disadvantages of easy slipping, low transmission ...
