Abstract

The invention discloses a planetary gear continuously variable transmission which comprises an intelligent controller, a planetary gear set and a planet carrier speed regulating mechanism. The planetary gear set comprises a transmission shaft inner gear ring and a planet carrier inner gear ring, a first transmission shaft is connected with the transmission shaft inner gear ring, a sun gear is arranged in the transmission shaft inner gear ring, the sun gear is connected with a second transmission shaft, and three planet gears are arranged at the rear end of the planet carrier inner gear ring; the planet carrier speed regulating mechanism comprises a pump body, three gear pumps which are annularly distributed are arranged in the pump body, a driving gear of each gear pump is coaxially and fixedly connected with a speed regulating gear, and the speed regulating gears mesh with the planet carrier inner gear ring; and an electric flow regulating valve is arranged on an oil discharge channelof each gear pump, and the three electric flow regulating valves are electrically connected with the intelligent controller. The planetary gear continuously variable transmission is simple and compact in structure, high in mechanical strength, long in service life and convenient and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of transmissions, in particular to a planetary gear continuously variable transmission. Background technique [0002] A continuously variable transmission can continuously change gear ratios between a maximum value and a minimum value without discrete steps. The continuously variable transmission maintains an ideal relationship between the engine and the wheels, improving fuel efficiency and acceleration. [0003] Many types of continuously variable transmissions are known, such as variable diameter pulley (VDP), toroidal CVT and cone CVT. Although the existing continuously variable transmission design can improve the efficiency of the overall powertrain, its structure is relatively complicated, the transmission efficiency is low, and it cannot bear large torque. Contents of the invention [0004] The purpose of the present invention is to solve the problems of the above-mentioned prior art, and provide ...
