Abstract

The utility model relates to the field of motorcycle, in particular to a commutator for motorcycles. The commutator comprises a box body, a driving chain wheel, chains, a driven chain wheel, and a driving shaft and a driven shaft mounted on the box body, wherein the driving chain wheel and a driving gear are installed on the driving shaft; the driving chain wheel drives the driven chain wheel mounted on the driven shaft through the chains; a driven gear is installed on the driven shaft and can be meshed with the driving gear; and a poking fork capable of poking the driving gear is arranged in the box body. The utility model can realize multiple installation methods, and has the advantages of simple structure, low cost and reliable use.

Description

The commutator that is used for motorcycle

Technical field

The utility model relates to the motorcycle field field, especially a kind of commutator that is used for motorcycle.

Background technique

At present, a lot of motorcycles have forward gears and reverse gear, and gear must be positioned at neutral gear position when motorcycle parking or startup, the structure more complicated that it adopts, and volume is big, and it is difficult to make, and maintenance bothers.

The model utility content

In order to overcome the deficiency of existing motorcycle commutator complexity, the utility model provides a kind of commutator that is used for motorcycle.

The technological scheme that its technical problem that solves the utility model adopts is: a kind of commutator that is used for motorcycle, comprise casing, drive sprocket, chain, by movable sprocket and be installed in driving shaft and driven axle on the casing, drive sprocket and driving gear are installed on the driving shaft, drive sprocket by chain drive be installed on the driven axle by movable sprocket, driven gear is installed on the driven axle, and can mesh with driving gear, also be provided with the fork that to stir driving gear in the casing.

The beneficial effects of the utility model are that the utility model can be realized multiple mounting type, both simplify the structure, increased intensity and saved raw material again, have guaranteed the reliability of commutation, therefore, have simple in structurely, and cost is low, the service-strong advantage.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model embodiment 1 a schematic representation;

Fig. 2 is the utility model embodiment 2 a schematic representation;

Fig. 3 is the utility model embodiment 3 a schematic representation.

1. casings among the figure, 2. drive sprocket, 3. chain, 4. by movable sprocket, 5. driving shaft, 6. driven axle, 7. driving gear, 8. fork, 9. driven gear.

Embodiment

With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.

As Fig. 1 is the utility model embodiment 1 schematic representation, a kind of commutator that is used for motorcycle, comprise casing 1, drive sprocket 2, chain 3, by movable sprocket 4 and be installed in driving shaft 5 and driven axle 6 on the casing, drive sprocket 2 and driving gear 7 are installed on the driving shaft 5, drive sprocket 2 by chain 3 drive be installed on the driven axle 6 by movable sprocket 4, driven gear 9 is installed on the driven axle 6, and can mesh with driving gear 7, also is provided with the fork 8 that can stir driving gear 7 in the casing 1.Engine revolution moment passes to driving gear 7 successively by driving shaft 5, and fork 8 makes driving gear 7 finish neutral in the neutral position.

As Fig. 2 is the utility model embodiment 2 schematic representation, engine revolution moment passes to driving gear 7 successively by driving shaft 5, fork 8 makes the clutch on the driving gear 5 be meshed with drive sprocket 2, pass to chain 3, pass to successively by movable sprocket 4, pass to driven axle 6, finish forward gears.

As Fig. 3 is the utility model embodiment 3 schematic representation, and engine revolution moment passes to driving gear 7 successively by driving shaft 5, and fork 8 makes driving gear 7 be meshed with driven gear 9, passes to driven gear 9, finishes reverse gear thereby drive driven axle 6.

With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
