Problems solved by technology

[0003] 1. When the motorcycle starts and runs at low speed, the centrifugal force of the centrifugal roller is small, the inclined plate presses the moving wheel to move axially, the diameter of the belt on the driving wheel is small, and the transmission efficiency is low
If the centrifugal force of the centrifugal roller is increased by increasing the weight of the centrifugal roller, the wear of the centrifugal roller will be large, which will obviously reduce the service life of the continu

Abstract

The stepless speed change driving wheel for motorcycle includes engine main shaft, on the engine main shaft a fixed wheel, a moving wheel and a slop board are set, in the moving wheel a centrifugal roller conduit and centrifugal roller are set, the moving wheel can be axially moved mo the sliding bush of engine main shaft, the fixed wheel and engine main shaft can be synchronsouly rotated, between the moving wheel and engine main shaft a driving mechanism is set, and between the moving wheel and slop board an elastic component, said elastric component adopts spreader spring perfectly, so thatthe rotating speed and torque of driven wheel can obtain more reasonable distribution. As compared with existent motorcycle it can save fuel by about 20%.

Description

Technical field: [0001] The invention relates to the field of continuously variable transmission devices for motorcycles, in particular to a continuously variable transmission driving wheel for motorcycles. Background technique: [0002] The general structure of the driving wheel of the existing continuously variable transmission motorcycle is: the engine main shaft is provided with a fixed wheel, a moving wheel and a slope plate, and the moving wheel is provided with a centrifugal roller groove and a centrifugal roller; Move up the axis. When the main shaft of the engine rotates, the centrifugal roller in the moving wheel generates centrifugal force to push the moving wheel to move axially, so that the diameter of the belt on the driving wheel changes, thereby changing the speed and output torque of the driven wheel. There is following deficiency in this kind motorcycle continuously variable speed driving wheel: [0003] 1. When the motorcycle starts and runs at a low spe...
