Description
Technical field:
The present invention relates to motorcycle stepless transmission system field, particularly a kind of motorcycle stepless speed change driving wheel.
Background technology:
The driving wheel general configuration of existing stepless speed-change motorcycle is: engine spindle is provided with tight pulley, moves wheel and slope board, moves wheel and is provided with centrifugal roller conduit and centrifugal roller; Mobile wheel can move axially on the main shaft sliding sleeve.When engine spindle rotated, the centrifugal roller that moves in the wheel produced the centrifugal force pulls moving shaft to moving, and the wheel of belt on driving wheel directly changed, thereby changes rotating speed and output torque on the flower wheel.This kind motorcycle stepless speed change driving wheel has the following disadvantages:
1, when motor bike in starting, during low speed driving, the centnifugal force of centrifugal roller is less, slope board compressing moving shaft is little to moving, the wheel of belt footpath is less on the driving wheel, driving efficiency is low.If adopt the mode that increases centrifugal roller weight to increase the centnifugal force of centrifugal roller, centrifugal roller wearing and tearing are big, can obviously reduce the service life of motorcycle stepless speed change driving wheel.
2, motor bike is when loose oil return door, and the wheel footpath of belt on driving wheel diminishes suddenly, makes motor bike that the sense of pause be arranged, and traveling comfort of riding and sliding property are poor.
3, motor bike is in medium-to-high grade low oil travels, and when needing brish acceleration, transmitting ratio changes slower, and revolution ratio changes big, and engine drag is big.
Summary of the invention:
At above deficiency, the contriver has proposed a kind ofly to improve motor bike service life, driving efficiency, saving fuel oil, sail the more comfortable motorcycle stepless speed change driving wheel of row.It comprises: engine spindle, engine spindle are provided with tight pulley, move wheel and slope board; Move in the wheel and be provided with centrifugal roller conduit and centrifugal roller, mobile wheel can move axially on the engine spindle sliding sleeve; Tight pulley and engine spindle rotate synchronously; Move between wheel and engine spindle and be provided with transmission device.Be provided with elastic component between described mobile wheel and the slope board, elastic component preferably adopts stage clip.
Owing to move between wheel and the slope board and be provided with elastic component (stage clip), motor bike is when starting, low speed driving, the present invention moves the force action that wheel is subjected to elastic component (stage clip) elastic force and centrifugal roller centnifugal force, make moving shaft relatively large to moving, thereby changed the wheel footpath of belt, improved driving efficiency.
Owing to move between wheel and the slope board and be provided with elastic component (stage clip), when motor bike during, move wheel and under the effect of stage clip, slowly move, thereby the wheel footpath of belt on driving wheel slowly diminished at loose oil return door, make motor bike not have to pause sense, sail that row is more comfortable, sliding property is better.And can not form belt shake out body, reduce the noise and the wearing and tearing of power-transfer clutch.
Owing to move between wheel and the slope board and be provided with elastic component (stage clip), when motor bike needs brish acceleration in the low oil of top grade travels, move wheel under the effect of stage clip, transmitting ratio changes very fast, and engine drag is little.
Motorcycle stepless speed change driving wheel of the present invention makes the rotating speed of flower wheel and moment of torsion obtain more rational distribution owing to be provided with elastic component (stage clip) between mobile wheel and slope board.Promptly when both engine speeds were identical, the stepless change flower wheel that motor bike of the present invention has been installed can obtain higher rotating speed or moment of torsion.After motorcycle stepless speed change driving wheel of the present invention replaced existing motorcycle stepless speed change driving wheel, ride 100 kilometers in identical highway section, the oil consumption of existing motor bike is 2.65 liters, and is 2.1 liters with the oil consumption of motor bike of the present invention, fuel-economizing about 20%.
In the present invention, preferably be provided with the elasticity dialing part in the described centrifugal roller conduit.Can make centrifugal roller be adjacent to slope board all the time and can not send abnormal sound because of being subjected to slope board compressing.
In the present invention, described stage clip preferably is provided with spring abutment, and spring abutment is placed in and moves on the wheel.Spring abutment is beneficial to the mobile wheel of protection and avoids wearing and tearing, is convenient to make processing simultaneously.
In the present invention, being provided with transmission device between described mobile wheel and engine spindle can be: be located by connecting between slope board and engine spindle, slope board is provided with driver slot, moves wheel and is provided with and driver slot corresponding driving guidepost.Adopt this kind transmission device, less to the structural modification of original motorcycle stepless speed change driving wheel, be beneficial to production.Because tight pulley, mobile wheel, slope board rotate synchronously, make the rolling track of each centrifugal roller in slope board stable, make that its reliability is higher.After increasing elastic component (stage clip) between mobile wheel and the slope board, the performance of motor bike can be improved significantly.
In the present invention, being provided with transmission device between described mobile wheel and engine spindle can be: at engine spindle with move on the wheel and be provided with gear and the tooth cover that matches.Adopt this kind transmission device, though it has increased the manufacture difficulty of motorcycle stepless speed change driving wheel.But after increasing elastic component (stage clip) between mobile wheel and the slope board, the performance of motor bike also can be improved significantly.
In the present invention, being provided with transmission device between described mobile wheel and engine spindle can also be: be provided with locating dowel pin between engine spindle sliding sleeve and mobile wheel, move to have on wheel or the engine spindle sliding sleeve and can hold the axially movable therein conduit of locating dowel pin; Move wheel and be provided with the driving guidepost, slope board is provided with and drives guidepost corresponding driving groove.Adopt this kind transmission device, though it has increased the manufacture difficulty of motorcycle stepless speed change driving wheel.But after increasing elastic component (stage clip) between mobile wheel and the slope board, the performance of motor bike also can be improved significantly.
