Problems solved by technology

Since the number of teeth of each gear set is fixed, the speed ratio of each gear is a fixed value. It consists of gears that can slide axially on the shaft and mesh with different gears to achieve the purpose of speed change, so its transmission ratio is discontinuous. Control is cumbersome
In order to solve the problems of discontinuous transmission ratio and cumbersome speed change control of manual transmission, the invention provides a continuously variable speed change mechanism, which not only has a continuous transmission ratio, but also facilitates speed change control

Abstract

The invention relates to a mechanical stepless speed variator having the continuously changed drive ratio, convenient variable speed control and large speed adjusting range; wherein a crankshaft drives a group of rocker arms, a group of rocker arms drive a group of unidirectional clutches, each group of unidirectional clutches drive a middle shaft to rotate in the same rotary direction, the middle shaft transfers the force to a middle shaft crankshaft, and the middle shaft crankshaft drives again a group of unidirectional clutches to drive an output shaft. The drive ratio is changed through changing the distance between the middle shaft and the input and output shafts.

Description

Technical field [0001] The invention relates to a speed change mechanism, in particular to a mechanical stepless speed change mechanism. Background technique [0002] Currently, known manual transmissions are driven by gear sets. Since the number of teeth of each gear set is fixed, the speed ratio of each gear is a fixed value. It consists of gears that can slide axially on the shaft and mesh with different gears to achieve the purpose of speed change, so its transmission ratio is discontinuous. The controls are cumbersome. In order to solve the problems of discontinuous transmission ratio and cumbersome speed change control of manual transmission, the present invention provides a continuously variable speed change mechanism, which not only has continuous transmission ratio, but also facilitates speed change control. Contents of the invention [0003] The technical solution adopted by the present invention to solve the technical problem is: drive a group of rocker arms w...
