Abstract

The utility relates to a dental pattern tire electromobile, which is characterized in that a drive gear wheel is directly fixed on a driving motor fixed on a frame via a motor bearing, and gears on the drive gear wheel is engaged with the gears outside the tire. The utility model has the advantages of simple structure, low costs of conversion, labor saving activation and energy resource saving, which is a novel driving electromobile.

Description

Flute profile tire Electrical Bicycle

Technical field

The utility model belongs to the bicycle field, particularly relates to a kind of flute profile tire Electrical Bicycle.

Background technology

The tire of dillies such as existing bicycle, three-wheel vehicle is rubber and makes as raw material, and its outside face is suppressed with lines, mainly be the friction force that lands that increases tire.And for directly making the tire of flute profile at outer surface of tire, and directly drive by drive motor, by retrieval, do not find as yet.

Summary of the invention

The utility model is for solving the technical matters that exists in the known technology, provide a kind of have simple and reasonable, laborsaving, and the flute profile tire Electrical Bicycle by drive motor direct drive flute profile tire.

The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:

The drive motor that is packed on the vehicle frame directly installs a driving gear by its motor shaft, and this driving gear is by made tooth on the tooth engagement flute profile outer surface of tire of system on it.

The utility model can also adopt following technical measures:

Motor is directly installed on behind the bicycle on the vehicle frame, the direct drive rear wheel.

Advantage and the good effect that the utlity model has are:

Outer surface of tire at dillies such as Electrical Bicycle, three-wheel vehicles is directly made flute profiles such as straight-tooth, arc tooth, herringbone tooth, helical teeth by modes such as mold pressings, the tooth of the driving gear engagement outer surface of tire by the drive motor that on vehicle frame, installs, thereby drive wheels motion.Because the arm of force of this structure is the longest, thereby also the most laborsaving, running time is the longest under the situation of using similar power supply.The utility model is simple in structure, and cost of manufacture is low, drives laborsavingly, saves the energy, is a kind of Electrical Bicycle of novel type of drive.

Fig. 2 is the partial enlarged drawing of Fig. 1;

Fig. 3 is that the A-A of Fig. 2 is to cutaway view.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, enumerate following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1, Fig. 2, Fig. 3.

The utility model is made of Electrical Bicycle vehicle frame 1, battery 5, drive motor 3, and battery is packed on the bracket.The tire 6 that is installed in the Electrical Bicycle on the wheel hub 9 is shaped on the flute profile tire of tooth 7 for its outside face, and drive motor is packed on the vehicle frame by fixed mount 2, and the drive motor that is illustrated as in the present embodiment is packed on the vehicle frame of back the direct drive rear wheel; Certainly also can be packed in drive motor on the front vehicle frame, drive front vehicle wheel.Drive motor directly installs an active 4 gears by its motor shaft 8, and this driving gear is by made tooth on the tooth engagement flute profile outer surface of tire of system on it.

The outer surface of tire of dilly such as Electrical Bicycle, three-wheel vehicle is directly made flute profile, the flute profile of the driving gear that drive motor drove and its couplings such as straight-tooth, arc tooth, herringbone tooth, helical teeth by modes such as mold pressings.

Claims
