Abstract

The invention provides a balanced type infinitely variable transmission, belongs to the technical field of transmissions and mainly solves the problem that in the prior art, when the function of infinitely variable speeds is achieved, the gear ratio is small, and the functions of a truck or other vehicles requiring big gear ratio can not be satisfied. The transmission comprises a first single-planet-row planet gear mechanism, a double-planet-row planet gear mechanism, a second single-planet-row planet gear mechanism and a damping device, wherein the first single-planet-row planet gear mechanism and the double-planet-row planet gear mechanism use a first planet gear support in common; the damping device is composed of a brake disc and a brake pad; the transmission is characterized in that a single gear ring or a double gear ring is fixedly connected with a planet gear support of the second single-planet-row planet gear mechanism, a sun wheel of the double-planet-row planet gear mechanism is slidably connected with an input shaft through a first shaft sleeve, and a gear ring of the second single-planet-row planet gear mechanism outputs power through an output shaft sleeve which is slidably connected with the input shaft. By means of the transmission, the range of the gear ratio of input and output is wider.

Description

technical field

[0001] The invention belongs to the technical field of transmissions, in particular to a balanced continuously variable transmission. Background technique

[0002] At present, when the balanced planetary gear continuously variable transmission and the balanced planetary mechanism continuously variable transmission realize the function of continuously variable transmission, the transmission ratio is small, which cannot meet the requirements of trucks or other functions that require a large transmission ratio. Contents of the invention

[0003] The problem to be solved by the present invention is to use three sets of planetary gear mechanisms to form a speed change mechanism, and to realize stepless speed change through a damping device while making the speed change ratio wider, specifically relating to a balanced continuously variable speed changer.

[0004] The technical scheme that the present invention takes for solving the problems of the technologies de...
