Description
Technical field:
The utility model relates to stepless speed variator, specifically mainly is the stepless speed variator that is used for motorcycle.
Background technique:
Existing stepless speed-change motorcycle, component wear is fast, and noise is big, and exhaust emissions is big, and its reason is: the clutch that motorcycle adopts is a centrifugal clutch, when motorcycle slows down, is difficult to cut off the inertial force of the speed of a motor vehicle, and driving wheel forces motor together to rotate.In the unsuitable too fast highway section of the speed of a motor vehicle,, then be difficult to bring into play the economic speed of motorcycle as streets and lanes, busiest section, obstacle road surface etc.When higher speed transformed, driving wheel can not get the useful horsepower of engine power to motorcycle by low speed; When motorcycle is worked under the light load condition, gear shift mode is that the engine spindle that adopts drives initiatively speed change disc assembly rotation, the generation centrifugal force of dishing out at a high speed of the centrifugal integument in the speed change dish rail slot initiatively, centrifugal pearl forces the slider disc of active speed change dish to overcome the pressure of the passive speed change dish spring in back, flabellum dish to active speed change dish is drawn close, and increases the initiatively middle speed belt diameter of speed change dish with this, dwindles the moving speed change dish intermediate belt diameter in back, reach the purpose that improves the speed of a motor vehicle, otherwise then slow down.Thus, the motorcycle speed change mainly is to utilize the slider disc extruding speed belt of the centrifugal force pulls active speed change dish of the centrifugal pearl generation in the active speed change dish, change the rotating diameter of speed belt, thereby realize the purpose of bull wheel band steamboat or steamboat band bull wheel, with this speed change, but when quickening, because the centrifugal force that centrifugal pearl produces exists unstable and consumes big problem, cause the useful load of motor all not to be delivered on the driving wheel, cause to drive the useful horsepower can not get power, when showing as motor and under light load, working, the oil consumption height, wearing and tearing are big, and exhaust emissions is big, and noise is big.
Existing oil saving stepless speed variator, rapid wear, poor stability.Assembly easily comes off, slip aluminium dish Heavy Weight.Its reason is: drive the rotation of fuel-economizing buncher by engine spindle, slip aluminium dish with drag flange, be promptly to close according to the rotating speed of motor height, promptly open certain distance, auxiliary variable speed spring in the spring protecting sleeve is and then flexible simultaneously, when slip aluminium dish with drag flange when separating, be enclosed within the termination of the auxiliary variable speed spring that drags the flange plush copper, will be close to spring protecting sleeve and stretch out one section formation arc, when slip aluminium dish to drag flange near the time, auxiliary variable speed spring in the spring protecting sleeve and then shrinks, like this: formed the auxiliary variable speed spring of arc, when shrinking and spring protecting sleeve formed strong friction, be enclosed within and drag auxiliary variable speed spring tip on the flange boss, also easily come off under action of centrifugal force, the aluminium dish of round edge shape has not only increased material, and has consumed engine power.
Summary of the invention:
The purpose of this utility model provides and a kind ofly can make that the stepless speed-change motorcycle oil consumption is low, noise is little, waste gas is few, good stability, and safety, and can prolong the oil saving stepless speed variator in motivation life-span.
In order to achieve the above object, the utility model by the following technical solutions: the utility model comprises initiatively speed change slider disc, centrifugal pearl door; On the excircle end face of edge active speed change slider disc, evenly be provided with a plurality of spring-loaded posts; On the side of pole socket, be provided with a plurality of spring established angles accordingly; The spring-loaded post is provided with locating slot, and guide rod one end holding is in locating slot, and the guide rod the other end is equipped with guiding piece, the spring established angle of guiding piece holding on pole socket; Pole socket is fixedly mounted on the centrifugal pearl door by screw rod, and spring is nested with on guide rod, is fixed on the guide rod by guiding piece.
On on the centrifugal pearl door, be provided with the step flange.
Initiatively the aluminium circle of speed change slider disc side is profile of tooth.
After adopting above technological scheme, guide rod and spring, guiding piece pole socket, the step flange, the cooperation of flute profile slip aluminium dish is exactly the centrifugal force in high rotating speed, and assembly can not come off, guide rod also well restraining spring under action of centrifugal force, form arc, guide rod is also little at guiding piece endoporus surface friction drag, whole like this assembly, durable safety, stable performance, profile of tooth aluminium dish is in light weight; Make stepless speed-change motorcycle explosive force strong, speed-raising is fast, and oil consumption is low, and noise is little, and waste gas is few, and has prolonged the life-span of motor.
Description of drawings:
Fig. 1 is the utility model assembling schematic representation.
Embodiment:
Contrast accompanying drawing below, the utility model is further described: as shown in Figure 1, the oil saving stepless speed variator device comprises initiatively speed change slider disc, centrifugal pearl door; On the excircle end face of edge active speed change slider disc, evenly be provided with a plurality of spring-loaded posts; On the side of pole socket 4, be provided with a plurality of spring established angles accordingly; It is characterized in that the spring-loaded post is provided with locating slot 7, guide rod 1 one end holdings are in locating slot 7, and the guide rod the other end is equipped with guiding piece 3, the spring established angle of guiding piece 3 holdings on pole socket 4; Pole socket 4 is fixedly mounted on the centrifugal pearl door by screw rod 8, and spring 2 is nested with on guide rod 1, is fixed on the guide rod 1 by guiding piece 3; On on the centrifugal pearl door, be provided with step flange 6; Be that initiatively the aluminium circle 5 of speed change slider disc side is profile of tooth.
