Abstract

The invention discloses an internal contact conical ring type continuously-variable transmission. Two conical wheels are in internal contact with two conical rings respectively, the stress of a contact area is small, and the service life can be improved. Meanwhile, the reliability is high and the power transmission efficiency is high. The continuously-variable transmission comprises a shell, an input shaft, a planetary line, the input conical wheel, the conical rings, the output conical wheel, an output shaft, a differential mechanism, an output gear, a loading mechanism and a speed changing mechanism, wherein the input shaft, the planetary line, the input conical wheel, the conical rings, the output conical wheel, the output shaft, the differential mechanism, the output gear, the loading mechanism and the speed changing mechanism are located in the shell. Power is transmitted between the output conical wheel and the input conical wheel through the conical rings which are arranged outside the two conical wheels in a sleeved mode. The loading mechanism is a hydraulic-mechanical loading mechanism formed by coupling a hydraulic part and a mechanical part. The speed changing mechanism is of a structure similar to a bearing, and speed changing is realized by pushing an outer ring to drive the conical rings.

Description

technical field

[0001] The invention relates to a continuously variable transmission device, in particular to an inner contact cone ring type continuously variable transmission device, which belongs to the technical field of motor vehicle power transmission. Background technique

[0002] At present, energy consumption and environmental pollution are becoming more and more serious around the world, and automobiles have an important impact on energy consumption and exhaust emissions. Therefore, many automobile manufacturers around the world are constantly improving and optimizing the structure of automobiles to improve the economy and power of automobiles and reduce emissions. The transmission, which is the core component of the power transmission system of an automobile, has been paid more and more attention by people. In current cars, the most widely used transmissions are manual transmissions and automatic transmissions. Because these transmissions need to shift gears freq...
