Infinitely variable transmission mechanism with bevel wheel

Abstract

The invention discloses an infinitely variable transmission mechanism with a bevel wheel. The infinitely variable transmission mechanism of the bevel wheel comprises a driving wheel set, at least one middle wheel set, and driven wheel sets of which the quantity corresponds to that of the middle wheel sets, wherein the driving wheel set, the middle wheel sets and the driven wheel sets are orderly arranged adjacently; an upper middle wheel is respectively contacted with two adjacent driving wheels and adjacent driven wheels for transmission; a lower middle wheel is also respectively contacted with two adjacent driving wheels and two adjacent driven wheels for transmission; and the work radius of the bevel wheel is changed by adjusting the distances of the middle wheel sets between the driving wheel set and the driven wheel sets to achieve infinitely variable transmission. The infinitely variable transmission mechanism can be applied to transmission field of various vehicles, various machines, and the like.

Description

technical field [0001] The invention relates to the technical field of mechanical friction transmission, in particular to a cone wheel continuously variable transmission mechanism. Background technique [0002] In the last ten years, CVT (Continuously Variable Trans-mission) technology has made great progress, and is currently widely used in the field of low-power vehicles. There are many types of continuously variable transmissions, among which the belt drive type and the traction drive type have been applied in automobiles, and they all transmit power by friction. Due to the low transmission efficiency of fluid type and electric type, only a small amount of them are currently used in special vehicles. [0003] The belt-driven continuously variable transmission mainly relies on variable-diameter driving and driven wheels and metal belts to achieve stepless change in speed ratio. It has high transmission efficiency and a wide range of speed changes. The best match between ...

Problems solved by technology

Although the structure of this type of planetary continuously variable transmission is relatively simple, due to the small changeable radius of the planetary friction wheel and the restriction of its transmission mode in the planetary mechanism, the transmission ratio range is small and the transmission power is small. Restricted its development and application scope

[0005] As we all know, the cone wheel continuously variable transmission mechanism has the advantages of stable transmission, low noise, simple structure, overload protection effect, various forms, etc., and has a wide range of applications; however, the current technology of the cone wheel continuously variable transmission mechanism still cannot reach the The same superior performance as the transmission type continuously variable transmission, if a new technical solution is adopted to improve the existing cone wheel continuously variable transmission mechanism, to improve the transmission efficiency and power of the cone wheel continuously variable transmission mechanism, so that it can reach even Beyond the superior performance of the belt-driven continuously variable transmission, it will definitely have good promotion and application value in this field
