Abstract

The invention relates to the technical field of automobile accessories, in particular to a CVT (Continuously Variable Transmission). The CVT comprises a power source, a first transmission structure, a second transmission structure, a driving belt pulley, a driven belt pulley and a shell, wherein the driving belt pulley comprises a first rotating disc, a first rotating shaft and multiple first supporting blocks; the first rotating disc is rotationally connected with the shell through the first rotating shaft; the first supporting blocks are sequentially arranged on the first rotating disc through the first transmission structure in a surrounding way; the power source is in transmission connection with the first transmission structure; the driven belt pulley comprises a second rotating disc, a second rotating shaft and multiple second supporting blocks; the second rotating disc is rotationally connected with the shell through the second rotating shaft; the second supporting blocks are sequentially arranged on the second rotating disc through the second transmission structure in the surrounding way; the power source is in transmission connection with the second transmission structure. According to the CVT disclosed by the invention, since the friction force between the belt and the first and the second supporting blocks is large, so that belt slipping is reduced, the speed changing efficiency is high, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a continuously variable transmission. Background technique [0002] Continuously variable transmission, which uses the drive belt and the variable working diameter of the main and driven wheels to transmit power, can realize the continuous change of the transmission ratio, so as to obtain the best match between the transmission system and the engine working conditions. [0003] The continuously variable transmission in the related art includes two pulleys and a metal belt, and the metal belt is sleeved on the two pulleys. Pulley 4 consists of two discs. The grooves in the middle of the two discs form a V shape. One of the discs is controlled by a hydraulic control mechanism. Depending on the engine speed, it can be separated and pulled together. V-shaped The groove also widens or narrows accordingly, raising or lowering the metal belt, thus changing the diameter of the metal ...
