Continuously variable transmission

Abstract

The invention provides a continuously variable transmission. The continuously variable transmission is provided with an outer shell, an inner cavity, a first planet gear set and a second planet gear set; a bucket wheel sun wheel is fixedly arranged on a first shaft penetrating through a first support frame; the bucket wheel sun wheel is located on the inner side of the first support frame; a bucket wheel planet wheel is arranged on the outer circumference of the bucket wheel sun wheel; the bucket wheel planet wheel is engaged with the bucket wheel sun wheel; the bucket wheel planet wheel and the bucket wheel sun wheel form a bucket wheel planet gear set; a third support frame is arranged adjacent to the bucket wheel sun wheel; a bucket wheel planet wheel shaft is fixed in the middle of thebucket wheel planet wheel; the interior of the bucket wheel planet wheel shaft is of a hollow structure; the planet wheel shaft penetrates through the first support frame, the hollow bucket wheel planet wheel shaft and a second support frame; and the planet wheel shaft is rotationally connected with the first support frame and the second support frame. The continuously variable transmission withthree control ends formed by the outer shell, the first shaft and a second shaft is provided and can be widely applied to the field of transmission.

Description

technical field [0001] The invention relates to a mechanical transmission device, in particular to a continuously variable transmission. Background technique [0002] The existing domestic patent authorization number is a continuously variable transmission with ZL2017205424112, and its technical solution is: a continuously variable transmission, including an input planetary gear set and an output planetary gear set, an input planetary gear set and an output planetary gear set There is a cavity planetary carrier between them. The cavity planetary frame includes a cavity input end cover and a cavity output end cover. A bucket wheel cavity shell is fixed between the cavity input end cover and the cavity output end cover. The inner side of the planetary gear set is connected to the input end cover of the cavity, and the inner side of the planetary gear set at the output end is connected to the output end cover of the cavity. There is a planetary gear connecting shaft in the mid...

Problems solved by technology

[0009] The present invention is to solve the problem that the planetary gear sets at both ends of the continuously variable transmission limit the position of the end covers, and it is difficult to implement revolution control on the end covers on both sides of the cavity planetary frame; , the noise is large; the planetary wheel shaft and the bucket wheel planetary wheel shaft are not concentric, the planetary wheel shaft is outside the center of the bucket wheel planetary wheel shaft, and the structural arrangement is complicated; the input and output ends are fixed, resulting in a single transmission performance; there is no intermediate housing Inner wall structure scheme; in the case of other structures unchanged, there is no technical problem of increasing torque transmission alternatives, providing a three control ends formed by the outer shell, the first shaft and the second shaft, and gear meshing inside the outer shell Oil-rich lubrication, the shaft of the planetary wheel and the shaft of the planetary wheel of the bucket wheel are coaxial, and the inner wall of the housing is provided with a semicircular cavity corresponding to the bucket wheel. The bucket wheel is located in the semicircular cavity, and the ring gear replaces the sun gear to increase the torque transmission.
