Problems solved by technology

Its disadvantage is: to increase the speed ratio, the engine must reach a certain speed, so that the centrifugal pressure plate can generate enough centrifugal force to change the speed ratio. This is the main reason why the fuel consumption of continuously variable transmission vehicles is higher than that of manual transmission vehicles. reason

Embodiment Construction

[0006] The technical solution adopted in the technical problem solved by the present invention is: it is characterized in that the centrifugal pressure plate and the main shaft on the driving wheel of the original continuously variable transmission mechanism are changed to sliding friction, and a belt groove (passive belt groove) is added on the centrifugal pressure plate at the same time. speed-regulating pulley), and a belt groove (active speed-regulating pulley) is also added on the static disc on the passive theory, and a triangular speed-regulating belt is used to connect these two belt grooves. When the motor vehicle starts to drive, the driven wheel The active speed-regulating pulley on the top will rotate accordingly, and at the same time, the passive speed-regulating belt on the driving pulley will be driven to rotate through the speed-regulating belt, so that the centrifugal pressure plate will generate centrifugal force and push the moving plate of the driving pulley ...

Abstract

A variable-speed driving mechanism of passive wheel is featured as changing press-disc and master shaft in centrifugal type on original variable-speed mechanism to be slide-abrasive type, adding one leather belt groove on centrifugal press-disc and also adding one leather belt groove on static disc of passive wheel, using a triangle speed regulation belt to connect two said belt grooves with each other for realizing purpose of using passive wheel to control variable-speed ratio.

Description

technical field [0001] The invention relates to a belt drive stepless speed change transmission mechanism, especially capable of controlling the speed change ratio by using driven wheels to optimize power and load. Background technique [0002] At present, the known continuously variable transmission mechanism for vehicles mainly includes belt type, and the belt type is divided into metal belt and rubber fiber belt. Type pressure plate, when the spindle speed increases, the centrifugal pressure plate will make the belt plate move to the static plate, forcing the belt track to move to the pulley circle, realizing stepless speed regulation. Its disadvantage is: to increase the speed ratio, the engine must reach a certain speed, so that the centrifugal pressure plate can generate enough centrifugal force to change the speed ratio. This is the main reason why the fuel consumption of continuously variable transmission vehicles is higher than that of manual transmission vehicles. ...
