Abstract

The invention provides a stepless speed regulator driven by a friction wheel. The stepless speed regulator driven by the friction wheel comprises a shell, an input shaft and an output shaft. The output shaft is connected with a second driving wheel. Three or more first driven wheels matched with a first driving wheel are symmetrically arranged on the outer side of the first driving wheel. Three or more second driven wheels matched with a second driving wheel are symmetrically arranged on the outer side of the second driving wheel. The number of the first driven wheels is equal to that of the second driven wheels, and the first driven wheels correspond to the second driven wheels in a one-to-one mode. Sliding shafts are connected to the first driven wheels or the second driven wheels and sleeved with conical wheels. The conical wheels correspond to each other in a one-to-one mode, and the two corresponding conical wheels are axially parallel and are opposite in installation direction. A ball lead screw mechanism is arranged inside the shell. A lead screw, the input shaft and the output shaft are located on the same straight line. A driven friction wheel on the basis of the friction wheel driving is arranged on a ball. According to the stepless speed regulator driven by the friction wheel, the drive ratio of the stepless speed regulator can be accurately controlled, abrasion to parts is small, and the driven friction wheel can smoothly displace on the surfaces of the conical wheels during running, so that the speed changing process is smoother, and a vehicle will not slow down or stop or change speed suddenly.

Description

technical field [0001] The invention relates to the field of continuously variable transmissions, in particular to a continuously variable transmission driven by friction wheels. Background technique [0002] Friction wheel transmission is a mechanical transmission that uses the friction force between two or more wheels that are pressed against each other to transmit power and motion. Friction wheel transmission can be divided into two types: fixed transmission ratio transmission and variable transmission ratio transmission. The fixed transmission ratio friction wheel transmission with basically fixed transmission ratio is divided into three types: cylindrical flat friction wheel transmission, cylindrical groove friction wheel transmission and conical friction wheel transmission. The first two types are used for transmission between two parallel shafts, and the latter type is used for transmission between two cross shafts. When working, there must be enough pressing force ...
