Description

A kind of inner tube-free wheel structure

Technical field

This utility model relates to steel ring without inner tube class manufacturing technology field, is specifically designed a kind of inner tube-free wheel structure.

Background technology

Wheel and tire are the vitals in automobile running system, and its function is: supporting car load；Relax the impulsive force transmitted by road surface；Produce driving force and brake force, automobile turning by tire with the adhewsive action existed between road surface and when travelling, produce the side drag of equilibrium centrifugation power, make automobile keep straight-line travelling direction.

Wheel is mainly to be suppressed by steel and is welded, and its outer shroud manufactures accurately, to assemble tubeless tire.As it is shown in figure 1, tire 101 is respectively angle faces, curved face contact with bcad seats 103 and the contacting of wheel rim 104 of wheel rim 102 in existing inner tube-free wheel structure, there is rigidity and intensity is poor, the shortcoming such as be easily deformed.

Summary of the invention

For the problems referred to above, the purpose of this utility model is that providing a kind of improves wheel stiffnesses and intensity, reduces Wheel deflection and tire dismantling convenient inner tube-free wheel structure.

For reaching above-mentioned purpose, the technical scheme that this utility model is proposed is: a kind of inner tube-free wheel structure, including wheel rim, spoke and valve cock, described wheel rim has rim gutter, is arranged on the rim width direction of rim gutter the bcad seats outside two and is arranged on the outer rim on the rim width direction of each bead seating portion；It is characterized in that: described rim gutter includes the first rim gutter and the second rim gutter；Tire interface plane that described wheel cause one is connected with bcad seats and be located at that wheel rim end is downward or revolute reinforcement extension composition；Having valve port on the second described rim gutter, described valve cock is installed on valve cock, and described valve cock is positioned at the outside of hole of spoke.

Preferably, described bcad seats is 5 ° with the angle of horizontal plane.

Preferably, described tire interface plane is 60 ° with the angle of horizontal plane.

Preferably, the first described rim gutter internal diameter is φ A, and the second rim gutter internal diameter is φ C, and described bcad seats lowest part internal diameter is Φ S, and φ S ＞ φ C ＞ Φ a.

Preferably, described extension of strengthening is made up of at least 2 connected curved surfaces or plane.

Preferably, described curved surface or plane are 4, and the angle between each curved surface tangent line be φ M, φ N, Φ G, and φ M, φ N, Φ G≤180 °.

Preferably, the height between described wheel rim end and bcad seats horizontal plane is T, and 8mm≤T≤32mm.

Use technique scheme, inner tube-free wheel structure described in the utility model, have the beneficial effect that

1) tire contacts with bcad seats and tire contact plane, by original angle faces, curved face contact, angle faces, angle faces contact are made into, change whole Impact direction and size, the wheel rim that this family of curves connects, strengthens extension in addition, can preferably bear tire contact plane direct stress, thus reduce wheel rim deformation, improve rigidity and intensity；

2) by arranging the first rim gutter and the second rim gutter, make tire dismantling convenient.

Fig. 2 is this novel described inner tube-free wheel structural representation；

Fig. 3 is that prior art inner tube-free wheel structure tyre and rim contacts schematic diagram.

Detailed description of the invention

Below in conjunction with the accompanying drawings and detailed description of the invention, this utility model is described further.

As shown in Figure 2 and Figure 3, inner tube-free wheel structure described in the utility model, including wheel rim 1, spoke 2 and valve cock 3, described wheel rim 1 has rim gutter 11, is arranged on the rim width direction of rim gutter 11 bcad seats 12 outside two and is arranged on the outer rim 13 on the rim width direction of each bcad seats 12；Described rim gutter 11 includes the first rim gutter 110 and the second rim gutter 111；Described wheel rim 13 is by a tire interface plane 130 being connected with bcad seats 12 and is located at that wheel rim 13 end is downward or revolute reinforcement extension 131 forms；Having valve port 1110 on the second described rim gutter 111, described valve cock 2 is installed on valve port 1110, and described valve cock 3 is positioned at the outside of spoke 2 air holes 21.

Further, bcad seats 12 is 5 ° with the angle of horizontal plane, and tire interface plane 130 is 60 ° with the angle of horizontal plane；The first described rim gutter 110 internal diameter is φ A, and the second rim gutter internal diameter 111 is φ C, and described bcad seats 12 lowest part internal diameter is Φ S, and φ S ＞ φ C ＞ Φ a.

Further, described extension 131 of strengthening is made up of 4 connected curved surfaces or plane；And the angle between each curved surface tangent line be φ M, φ N, Φ G, and φ M, φ N, Φ G≤180 °；Height between wheel rim end and bcad seats horizontal plane is T, and 8mm≤T≤32mm.

Concrete, inner tube-free wheel structure described in the utility model, compared with the inner tube-free wheel structure of prior art, wheel rim bcad seats, wheel rim change with tire contact plane, are angle faces, curved face contact originally, it is now angle faces, angle faces contact (as shown in Figure 3), changing whole Impact direction and size, wheel rim strengthens the coiled structure of extension in addition, can preferably bear tire contact plane direct stress, thus reduce wheel rim deformation, improve rigidity and intensity.

Additionally, wheel rim of the present utility model is higher than existing market rim, belong to cases of otherwise standard design, increasing flange height, be conducive to increasing lifting surface area, wheel rim is originally for being easiest to deform position, therefore, decrease the probability of deformation, make steel ring the most durable, meet development and the demand in market, more disadvantageous, wheel rim is increased and can be brought problem to tyre fixing, but this wheel rim of this utility model is by arranging (the i.e. first rim gutter and the second rim gutter) at the bottom of double flute so that this problem has been resolved.

Although specifically showing in conjunction with preferred embodiment and describing this utility model; but those skilled in the art should be understood that; in the spirit and scope of the present utility model limited without departing from appended claims; in the form and details this utility model is made a variety of changes, be protection domain of the present utility model.
