Abstract

The utility model relates to a reversing apparatus, which is provided with a box body. A drive shaft and a driven shaft are arranged on the box body through a bearing, a drive sprocket and a drive gear are arranged on the drive shaft, and a driven sprocket which is driven by the drive sprocket through a chain is arranged on the driven shaft. A driven gear which can be engaged with the drive gear is also arranged on the driven shaft, and a shifting fork which shifts the drive gear is arranged in the box body. The invention is characterized in that a forward gear is driven and completed directly by the chain, a back gear is driven and completed directly by the gears, and various installation methods can be realized. The utility model integrates the advantages of back gears with triple shafts and two half shafts, has the advantages of simple structure, low cost and reliable operation, and can be used widely for vehicles, such as motorcycles, special motorcycles, energy-saving and ultra-miniature household cars, carting cars, etc.

Description

Commutator

The present invention relates to the motor vehicle reversing arrangement, the commutator that particularly extraordinary motorcycle, energy-saving superminiature family car, kart are waited for bus.

At present, the commutator that the changement that advances Yu fall back that motorcycle, extraordinary motorcycle, energy-saving superminiature family car, kart are waited for bus generally adopts mainly contains so two kinds of patterns, and a kind of is two-semiaxle structure (also claiming the single shaft reverse gear).Second kind is three-axis structure.The major defect of these two kinds of structures is complex structures, and volume is big, makes the maintenance expenses height, and the ratio of standard piece, general part is low.

Task of the present invention is: overcome the deficiencies in the prior art, design a kind of simple in structure, manufacturing, maintenance cost is low, accepted standard part, general part ratio are big, the commutator of reliability, good endurance.

Task of the present invention realizes as follows: commutator has a casing, the twin shaft that casing has driving shaft and driven axle to constitute by Bearing Installation, drive sprocket and driving gear are housed on the driving shaft, be equipped with on the driven axle by chain by drive sprocket drive by movable sprocket, also be equipped with on the driven axle can with the driven gear of driving gear engagement, be contained in the fork that has to stir driving gear in the casing.

The present invention is owing to directly adopt the chain transmission, integrate three, the advantage of two-semiaxle reverse gear case and lift one's head form because driven axle can be made the two sides again, therefore can realize multiple mounting type, both simplified the structure, increase intensity and saved raw material again, guaranteed the reliability of commutation, the durability of use, therefore have simple in structure, cost is low, the service-strong advantage.

Fig. 1 is a kind of working state view of the utility model;

Fig. 2 is the another kind of working state view of the utility model;

Fig. 3 is the third working state view of the utility model.

Most preferred embodiment of the present invention, as figure, commutator has a casing 9, by bearing driving shaft 1 and driven axle 7 are housed on the casing, be fixed with drive sprocket 2 on the driving shaft, by feather key driving gear 5 be housed, the fork 4 that is contained on the casing is used to stir the driving gear commutation, be equipped with on the driven axle 7 by movable sprocket 8, driven gear 6, drive sprocket drives by movable sprocket by chain 3.

Its working procedure is: engine revolution moment passes to driving gear 5 successively by driving shaft 1, and fork 4 makes driving gear 5 be meshed with driven gear 6, passes to driven gear 6, finishes reverse gear as shown in Figure 1 thereby drive driven axle 7.

When state was as shown in Figure 2 worked, engine revolution moment passed to driving gear 5 successively by driving shaft 1, and fork makes driving gear finish the neutral gear action in the neutral position.

State working procedure shown in Figure 3 is: engine revolution moment passes to driving gear 5 forks 4 successively by driving shaft 1 makes the jaw clutch on the driving gear 5 be meshed with drive sprocket 2, pass to chain 3, pass to successively by movable sprocket 8, pass to driven axle 7, finish forward gears.

Claims

1, a kind of commutator, it has a casing by bearing driving shaft to be housed on it and driven axle constitutes twin shaft, it is characterized in that: drive sprocket and driving gear are housed on the driving shaft, be equipped with on the driven axle by chain by drive sprocket drive by movable sprocket, also be equipped with on the driven axle can with the driven gear of driving gear engagement, be contained in the fork that has to stir driving gear in the casing.
