Abstract

An embodiment of the invention discloses a transmission mechanism with free input rotation direction and constant output rotation direction, an oil pump system and a vehicle. The transmission mechanism comprises a driving piece, an intermediate transmission piece, a first driven piece, a second driven piece, a first roller pin clutch and a second roller pin clutch, wherein the first driven piece and the second driven piece are coaxially mounted on an output shaft through the second roller pin clutch and the first roller pin clutch respectively; the driving piece is in transmission connection with the intermediate transmission piece and the first driven piece at the same time; and the intermediate transmission piece is in transmission connection with the second driven piece, so that the first driven piece and the second driven piece can rotate in different directions. According to the embodiment of the invention, the purpose that a driving shaft rotates in two directions and the output shaft only rotates in one direction can be achieved under a simple structure; the transmission mechanism can be applied to an electric vehicle; the problems that a lubricating system fails and a whole vehicle lubricating oil path loses pressure due to reverse rotation of an oil pump in the CVT reverse gear process of the electric vehicle at present are solved; and the transmission mechanism can also be applied to other places where the rotation direction of the output shaft needs to be kept unchanged.

Description

technical field [0001] The invention relates to the technical field related to vehicle transmission, in particular to a transmission mechanism with free input rotation direction and output constant rotation direction, an oil pump system and a vehicle. Background technique [0002] In some transmission devices or equipment, it is required that the rotation direction of the output shaft does not change with the change of the rotation direction of the drive shaft, that is, the rotation direction of the output shaft needs to be kept constant when the rotation direction of the drive shaft changes. [0003] For example, with the rapid development of battery and electric control technology, electric vehicle technology is becoming more and more mature, the electric ratio of motor vehicles has further increased, the electric vehicle industry has entered a period of rapid development, and more and more CVTs for electric vehicles have been mentioned and considered. The optimally design...
