Abstract
The utility model relates to wheels of a vehicle, and in particular relates to a dual-convex-peak 15-degree direct current (DC) wheel without an inner tube. The dual-convex-peak 15-degree DC wheel comprises a rim, a wheel flange arranged on the rim and a tire seat inwards extending from the wheel flange, and is characterized in that a spoke protruding out of the wheel flange is welded on the inner side of the rim; the tire seat is connected with a first transition section connected with a left dual-shaped convex peak; the left dual-shaped convex peak is connected with a second transition section; the second transition section is connected with a tire accommodating deep groove; the tire accommodating deep groove is connected with a right dual-shaped convex peak; and the right dual-shaped convex peak is connected with a third transition section. The dual-convex-peak 15-degree DC wheel has the advantages of simple and rational structure, high high-speed performance, high energy conservation and high safety.
Description
(1) technical field
The utility model relates to a kind of wheel of vehicle, the 15 ° of DC inner tube-free wheels in particularly a kind of biconvex peak.
(2) background technology
For a long time, 15 ° of DC inner tube-free wheel rim structures adopt the mode of conventional confguration always, and are unalterable.That is: wheel rim → 15 ° bead seat → straight transitions section → dress tire deep trouth → 15 ° of bead seat → wheel rims.This structure exists very big defective: wheel in working order down, and is stressed concentrated, in case road conditions are not good; Under the underinflation situation; Be easy to cause the distortion of wheel, damage tire, damage vehicle frame etc., even bring great harm can for user's the security of the lives and property.Therefore, in order to address this problem, the 15 ° of DC inner tube-free wheels in a kind of biconvex peak have been invented.
(3) summary of the invention
The utility model is in order to remedy the deficiency of prior art, provide a kind of simple and reasonable, high speed performance good, good energy saving property, 15 ° of DC inner tube-free wheels in biconvex peak that safety is good.
The utility model is realized through following technical scheme:
The 15 ° of DC inner tube-free wheels in a kind of biconvex peak, the placenta that comprises wheel rim, is arranged at the wheel rim on the wheel rim and extends internally and form from wheel rim, it is characterized in that: said wheel rim inboard is welded with the spoke that protrudes from wheel rim; Placenta is connected with first transition phase; First transition phase is connected with the protruding peak of left dimorphism, and the protruding peak of left dimorphism is connected with second transition phase, and second transition phase is connected with dress tire deep trouth; Dress tire deep trouth is connected with the protruding peak of right dimorphism, and the protruding peak of right dimorphism is connected with the 3rd transition phase.
Offer centre hole on the said spoke, the centre hole periphery offers some mounting holes, and the mounting hole periphery offers some lightening holes.
Dress tire deep trouth left side is provided with valve hole on the said wheel rim.
The beneficial effect of the utility model is: simple and reasonable: intensity is high, lightness, and balance quality is good; High speed performance is good; Good energy saving property: in light weight, resistance is little, can save energy; Safety is good: structure rationally, thereby make wheel strength high, indeformable, reduced accident rate.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is the shaft section scheme drawing of the utility model;
Accompanying drawing 2 is looked scheme drawing for the left side of accompanying drawing 1;
Among the figure, 1 wheel rim, 2 wheel rims, 3 placentas, 4 spokes, 5 first transition phases, the protruding peak of 6 left dimorphisms, 7 second transition phases, 8 dress tire deep trouths, the protruding peak 10 of 9 right dimorphisms the 3rd transition phase, 11 centre holes, 12 mounting holes, 13 lightening holes, 14 valve holes.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the utility model.The placenta 3 that this embodiment comprises wheel rim 1, is arranged at the wheel rim 2 on the wheel rim 1 and extends internally and form from wheel rim 2; Wheel rim 1 inboard is welded with the spoke 4 that protrudes from wheel rim 2, and placenta 3 is connected with first transition phase, 5, the first transition phases 5 and is connected with the protruding peak 6 of left dimorphism; The protruding peak 6 of dimorphism, a left side is connected with second transition phase 7; Second transition phase 7 is connected with dress tire deep trouth 8, and dress tire deep trouth 8 is connected with the protruding peak 9 of right dimorphism, and the protruding peak 9 of right dimorphism is connected with the 3rd transition phase 10.Offer centre hole 11 on the spoke 4, centre hole 11 peripheries offer some mounting holes 12, and mounting hole 12 peripheries offer some lightening holes 13.Dress tire deep trouth 8 left sides are provided with valve hole 14 on the wheel rim 1.
Adopt 15 ° of DC inner tube-free wheels in a kind of biconvex peak of the utility model, adopt advanced high-precision spinning machine, revolve and make the equicohesive spinning spoke 4 in non-cross section; Adopt advanced flash butt welder with wheel rim 1 Flash welding; Adopt the dress tire deep trouth 8 of 15 ° of DC inner tube-free wheel wheel rims 1 to be connected the turning force part with both sides placenta 3, increased by one roll extrusion, two wheel rims 2, deep trouth respectively, the protruding peak of two road roll extrusion is one-step forming just; Three road roll extrusion protruding peak moulding; Increased together protruding peak 6 of left dimorphism and the protruding peak 9 of right dimorphism respectively, at the non-stress position corresponding through the roll extrusion attenuate section thickness, at last whole wheel rim 1 integer is become the novel wheel rim 1 in biconvex peak.Offer lightening hole 13 on the spoke 4, can alleviate wheel weight, reduce production costs, also can play equilibrium activity.Dress tire deep trouth left side offers valve hole 14 on the wheel rim, and the convenient inflation of tire of giving also can make valve hole 14 receive certain protection.
