Abstract
The utility model relates to a motorcycle chain pulley which is composed of a chain pulley movable disk, a flange, dustproof plates and screw rods, wherein the chain pulley movable disk is composed of chain pulley external teeth and inner ratchet wheel oblique teeth, and the lower end of the inner ratchet wheel oblique teeth is provided with the flange. Both ends of the flange are provided with slots, wherein the slot on one end of the flange is provided with an elastic sheet of which the upper end is provided with a wedge, and a roller is arranged in the slot on the other end of the flange. Both sides of the chain pulley movable disk are provided with the dustproof plates on which the screw rods are arranged. The utility model has the advantages of simple structure and convenient operation, can reduce a driver's frequent operation, and diminish the abrasion of members in an engine to obtain the purpose of oil saving.
Description
Technical field
The utility model relates to the motor bike driving device, relates in particular to a kind of chain wheel of motorcycle.
Background technology
At present, crawler body in the known two-wheeled motorcycle drive structure is to be formed by connecting by sprocket wheel, driving cog and chain, motor bike advances, speed change is to improve rotating speed and gearshift acquisition power and raising speed by driving engine, after reaching certain speed, in order to reach the fuel-economizing purpose, must make power-transfer clutch leave or change neutral gear and realize.This method chaufeur palpus frequent operation makes the engine interior component wear accelerate easily.And fuel-saving apparatus for motor cycle, the product on the market has products such as fuel-economizing carburettor, fuel-economizing ring, but its shortcoming is to use the time short, and fragile.
Summary of the invention
The purpose of this utility model just provides a kind of chain wheel of motorcycle that can make the motor bike fuel-economizing.
The technical solution of the utility model is achieved in that a kind of chain wheel of motorcycle, it is made up of sprocket wheel Advance plate, flange, dust guard, screw rod, the sprocket wheel Advance plate is made of sprocket wheel external tooth and handle ratchet wheel helical teeth, be provided with flange in handle ratchet wheel helical teeth lower end, on the two ends of flange, have groove, wherein be provided with shell fragment in the groove on flange one end, the shell fragment upper end is provided with voussoir, is provided with roller in the groove on flange is held in addition.Be provided with dust guard in sprocket wheel Advance plate both sides, on dust guard, be provided with screw rod.
The utility model has the advantages that simple in structurely, easy to operate, can reduce the behavior of chaufeur frequent operation, reach the fuel-economizing purpose, reduce the engine interior component wear.
Description of drawings
Fig. 1 is the utility model chain wheel of motorcycle semi-sictional view structural representation;
Fig. 2 is the sectional structure scheme drawing that the utility model chain wheel of motorcycle left side is looked.
The specific embodiment
As shown in Figure 1, 2, a kind of chain wheel of motorcycle, it is made up of sprocket wheel Advance plate, flange 2, dust guard 6, screw rod 7, the sprocket wheel Advance plate is made of sprocket wheel external tooth 1 and handle ratchet wheel helical teeth 8, be provided with flange 2 in handle ratchet wheel helical teeth 8 lower ends, on the two ends of flange 2, have groove, wherein be provided with shell fragment 5 in the groove on flange 2 one ends, shell fragment 5 upper ends are provided with voussoir 3, are provided with roller 4 in the groove on flange 2 is held in addition.Be provided with dust guard 6 in sprocket wheel Advance plate both sides, on dust guard 6, be provided with screw rod 7.
The utility model principle of work is: when motorcycle initiating is put into gear starting, chain wheel of motorcycle rotates by the strength that the chain gear tooth passes over, block under shell fragment 5 effects of 3 lower ends of the voussoir on the flange 2 lower end of handle ratchet wheel helical teeth 8, during sprocket rotation, drive flange 2 and wheel and rotate together.When the palpus fuel-economizing, as long as reduce oil mass, allow engine idling operation, at this moment, the strength speed that the rotating speed of wheel and flange 2 passes over greater than sprocket wheel, handle ratchet wheel helical teeth 8 on the sprocket wheel to pressing down, makes flange 2 separate with sprocket wheel the voussoir on the flange 23, and wheel and flange 2 keep former speed to rotate.When motorcycle speed drops to this grade acceleration/accel, need only refuel the rotating speed that improves driving engine, the strength that chain passes over drives sprocket wheel external tooth 1 and rotates, when sprocket wheel external tooth 1 speed during greater than wheel and flange 2 rotating speeds, handle ratchet wheel helical teeth 8 is blocked on shell fragment 5 bullets by the voussoir on the flange 23, drive flange 2 and rotate, wheel and flange 2 rotate together.
