Abstract

The present invention relates to a skidproof sludge discharge structure of an aluminum alloy wheel ring of a bicycle, wherein stripes of which the cross sections present corrugating shapes or jagged shapes are directly pressed and molded on the side surface of the aluminum alloy wheel ring by an aluminum pressing module. The stripes have the function of friction force increment during braking, and when the bicycle is ridden on muddy ground, snowy ground or wet and slippery ground, tenuousness sludge or small drops can be guided into the stripes according to the stripes. Humps on the surfaces of the stripes are in contact with a brake so as to prevent a danger of braking slippage due to the fact that the brake is isolated by sludge.

Description

The antiskid mud-removing structure of aluminium alloy rim of bicycle

The present invention relates to bicycle, relate to bicycle rim especially.

Behind the invention bicycle; be that widely people like and generally use; but after being that the steam turbine car is comparatively popularized; though the situation that comparatively disappears is arranged; but because the importance of people's vigilance environmental protection; can not pollute and have the effect of body-building, motion for bicycle; be and gradually paid attention to by common people; for promoting the Occupation coefficient of bicycle; the setting of exclusive bike lane is more arranged; and be most important with wheel rim in the bicycle, because wheel rim removes and supports whole weight, and the auxiliary effect of tool brake.

Consult shown in Fig. 1,2, after bicycle wheel rim 1 its making moulding of commonly using, be wheel rim 1 to be installed on the lathe whole wheel rim side 2 of getting on the bus, so that molded surface is able to is smooth, for brake can normally recline, but because wheel rim is smooth state, when bicycle is passed through marshy area or snowfield, wet and slippery ground, mud, water droplet and be adhered on 2 surfaces, the smooth side of wheel rim, brake can't effectively press in the wheel rim surface, for mud, the isolated phenomenon of braking and skidding that produces of water droplet, be its shortcoming.

Purpose of the present invention provides a kind of antiskid mud-removing structure of aluminium alloy rim of bicycle, and the brake that it can avoid contacting with wheel rim effectively skids when brake, and the effect of friction force when increasing brake is arranged.

For achieving the above object, the invention provides a kind of anti-skidding spoil disposal structure of aluminium alloy rim of bicycle, wherein the bicycle wheel rim is made with the aluminum alloy extrusion forming, be characterized in, when the wheel rim extrusion forming was made, the aluminium alloy rim side was all the striped that the direct extrusion molding section of aluminium extruded type is the wavy type of height.

According to embodiments of the invention, the wavy type striped of above-mentioned height can be the low wavy type striped of a Senior Two; Also can be zig-zag type striped.

The present invention is owing to be provided with the wavy striated structure of height in the wheel rim side, except that the friction function that has when increasing brake, more when passing through marshy area, can fine mud or water droplet be imported this striped by striped, and contact with brake with the protruding place of striated surface, thereby can avoid because of brake be the isolated skid hazards situation of braking that produces of mud.

Relevant the technology used in the present invention, means and effect are after lifting a preferred embodiment now and cooperating graphic being described in more detail in.

Fig. 1 is a schematic perspective view of commonly using the bicycle wheel rim.

Fig. 2 is a sectional schematic diagram of commonly using the bicycle wheel rim.

Fig. 3 is the schematic perspective view of aluminium alloy rim of bicycle of the present invention.

Fig. 4 is the one preferred embodiment sectional schematic diagram of the antiskid mud-removing structure of aluminium alloy rim of bicycle of the present invention.

Fig. 5 is the one preferred embodiment striped section enlarged diagram of the antiskid mud-removing structure of aluminium alloy rim of bicycle of the present invention.

Fig. 6 is another preferred embodiment sectional schematic diagram of the antiskid mud-removing structure of aluminium alloy rim of bicycle of the present invention.

Fig. 7 is another preferred embodiment striped section enlarged diagram of the antiskid mud-removing structure of aluminium alloy rim of bicycle of the present invention.

Fig. 8 is a three-dimensional sectional schematic diagram of the present invention.

Consult shown in Figure 3, it is the schematic perspective view of the antiskid mud-removing structure of aluminium alloy rim of bicycle of the present invention, chase 11 positions of wheel rim 10 central authorities are in order to the installing tire, be provided with some holes 12 in order to installing Shu Zi and also make on the wheel rim 10, it mainly is the two sides 13 of

aluminium alloy rim

10,14 positions, make the striped 20 that section is height contoured shape or zig-zag type, must be when bicycle be passed through marshy area with its striped 20, muddy fine mud or water droplet must be imported and be discharged by the recess 21 of 20 of stripeds, and can not have influence on brake 30 normal brake functions;

Above-mentioned wheel rim 10 and striped 20 are to make simultaneously in the one-body molded mode of aluminium extruded type, exempt machinery (lathe) but the loaded down with trivial details and cost-cutting of reprocessing.

Consulting shown in Fig. 4,5,8, is the one preferred embodiment sectional schematic diagram of the antiskid mud-removing structure of aluminium alloy rim of bicycle of the present invention.Striped section enlarged diagram and three-dimensional sectional schematic diagram, wherein the striped 20 of the low wavy type of a Senior Two is made in aluminium alloy rim 10

sides

13,14, this striped 20 is by after the direct extrusion molding of aluminum alloy, aluminium alloy rim 10

sides

13,14 promptly do not need through special CNC mechanical treatment again, and the low wavy type striped 20 of the Senior Two after this direct extrusion molding has the effect of the friction force when increasing brake;

When two low wavy type stripeds 22 in the low wavy type striped 20 of one Senior Two of aluminium alloy rim 10

sides

13,14 directly crowded types can make wheel rim 10

sides

13,14 pass through marshy area fine mud water droplet is imported in these two low wavy type striped 22 recesses 21, and be positioned at the high wavy type striped 23 at protruding place, this moment, high wavy type striped 23 can contact with brake 30, and reaching when the low wavy type striped 20 of a Senior Two can avoid brake 30 to contact with aluminium alloy rim 10

sides

13,14 that are covered with mud has the phenomenon of skidding to produce.

Consult shown in Fig. 6,7, be another preferred embodiment sectional schematic diagram and the striped section enlarged diagram of the antiskid mud-removing structure of aluminium alloy rim of bicycle of the present invention, wherein the zig-zag type striped 24 of these aluminium alloy rim 10

sides

13,14 by the direct extrusion molding of aluminum alloy after, aluminium alloy rim 10

sides

13,14 also do not need through machine up again, and the zig-zag type striped 24 after this direct extrusion molding has the function of the friction force when increasing brake;

In addition, aluminium alloy rim 10 directly squeezes the zig-zag type striped 24 of type when passing through marshy area, be that fine mud or water droplet are imported recess 21, and contact with brake 30 with the protruding place 25 of zig-zag type striped 24, therefore, these zig-zag type striped 24 functions have the skid hazards facts when avoiding brake 30 to contact with aluminium alloy rim 10

sides

13,14 that are covered with mud.
