According to the spliced wide-base tubeless wheel rim, two intersected planes are added to the lower end parts of wheel flange parts of the left half rim and the right half rim respectively, so that the thicknesses of the materials at the wheel flange parts are increased, the intensity at the parts is enhanced, the parts are not prone to be deformed when a wheel bears larger load, and the safety performance is increased. By means of the method of welding the three parts, namely, the left half rim, the splicing rim and the right half rim, the wheel flange parts at two ends are manufactured respectively with a profile hot rolling process instead of large-tonnage rolling equipment, and a profile which meets the requirements can be manufactured; a standard profile can accomodate finished products in bulk, so that bulk and large-scale production is effectively guaranteed; and a cylindrical barrel is used in the middle for connecting the left wheel flange part and the right wheel flange part at two ends, and the width of the cylindrical barrel can be set freely, so that the wheel rim with any desirable section can be manufactured.
Description
Technical field
The utility model relates to a kind of inner tube free wheel rim, more particularly, relates to a kind of spliced wide basic inner tube free wheel rim.
Background technology
Since the white birth of inner tube-free wheel, it is compared because advantages such as its distinctive safety, energy savings with inner tube of a tyre wheel is arranged, gradually by customer acceptance, the use of inner tube-free wheel arises from Europe, the U.S. at first, more than 95%, the Taiwan of Japan, Korea S, China is also popularized inner tube-free wheel in a large number in the eighties and is used at American-European inner tube-free wheel tire Occupation coefficient.
China also used from car at first gradually since the initial stage nineties, since entering 21 century along with country's strict day by day to the energy-saving and emission-reduction requirement, the oil resources growing tension, recent years, inner tube-free wheel was also more and more in the use of commercial vehicle/comm..vehicle, and it is a trend that the inner tube-free wheel replacement has inner tube of a tyre wheel.The final development of automotive wheel is three changes: i.e. inner tube freeization, flattening and wide baseization, and have only this three to change and obtain simultaneously, the various performance competence exertions of automobile are to optimum regime.This three begins development from external racing car when melting and uses, now western countries' commercial vehicle/comm..vehicle oneself at the inner tube-free wheel that uses wide baseization, flattening.
Along with the use of wide section (wide base) inner tube-free wheel, originally two wheels of commercial vehicle/comm..vehicle and dress just can be replaced by the wide basic inner tube-free wheel of single-piece.Namely the inner tube-free wheel with a wide section replaces two-wheel, the weight of automobile can reduce greatly like this, originally use twins weight about 200Kg, after being changed to wide basic inner tube-free wheel, be about 100kg, calculate by 16 wheels of four original installations of a trailer, quantity had only 8 after car load was changed to wide basic wheel, weight more alleviates about 1600kg, excellent properties but also the energy-saving and emission-reduction benefit that not only can give play to vehicle after vehicle alleviates are obvious, and owing to be inner tube-free wheel, vehicle safety performance greatly improves.
But because the constraint of its version of inner tube-free wheel and manufacturing process, wheel rim is lower, easily cause the attenuate at wheel rim place material during manufacturing again, like this when commercial vehicle/comm..vehicle uses, because bearing load is bigger, Ackermann steer angle particularly, wheel rim bears big load, easily distortion occurs from wheel rim, cause tread flaking to have an accident when serious.Make wheel rim if adopt rolling section bar, though can improve the bearing capacity of wheel rim, but the rolling section bar of wide section needs very large-tonnage steel rolling equipment, also do not possess the section bar special rolling mill of rolling section width more than 11 inches at present both at home and abroad, therefore rely on present steel rolling level can't produce the wheel rim section bar of the wide section of integral type.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, (wide base) inner tube-free wheel version of a kind of spliced wide section of reinforcement is provided, after making the commercial vehicle/comm..vehicle twin wheel be changed to single tire, can satisfy lightweight that bigger load can make safety performance, automobile again and obtain actv. and promote.
The technical solution of the utility model is as follows:
A kind of spliced wide basic inner tube free wheel rim comprises spoke, wheel rim, and described wheel rim comprises left half wheel rim, splicing wheel rim, right half wheel rim, and a described left side half wheel rim and right half wheel rim link into an integrated entity by the splicing wheel rim.
As preferably, left half wheel rim, splicing wheel rim, right half wheel rim are the closed circular structure.

As preferably, the strong position of left false add is surrounded and is formed by a left side half vertical plane surface, left half horizontal plane.
As preferably, the outer rim of right half wheel rim is the right side half wheel rim of projection, right half wheel rim side direction in the wheel rim is connected with right half bead seat, the wheel rim inside face of right half wheel rim and right half bead seat junction extends the strong position of right false add that has thickness, and right half bead seat side direction in the wheel rim is connected with deep trouth portion.
As preferably, the strong position of right false add is surrounded and is formed by the right side half vertical plane surface, right half horizontal plane.
As preferably, the splicing wheel rim is one or more.
As preferably, the optional position of left half wheel rim or splicing wheel rim or right half wheel rim is provided with valve hole, is used for installing tire tube valve.
As preferably, spoke is installed on the optional position of left half wheel rim or splicing wheel rim or right half wheel rim.
The beneficial effects of the utility model are as follows:
What 1, each wheel rim position end portion of left and right two halves was not set up two intersects planes, this place material thickness is increased, thereby make this place intensity obtain reinforcement, and wheel is not yielding herein when bearing than load greatly, has increased safety performance.
2, adopt three welding manners, the manufacturing of hot-rolled profile technology is used at wheel rim position, two ends respectively, need not use the large-tonnage steel rolling equipment can go out satisfactory section bar.Standardized section bar can large quantities of storage finished stock storages, for effective guarantee has been done in the production of large quantities of extensiveization.
It is 3, middle that the simplified width of circle shape can freely be set with the left and right split of circle shape simplified connection two ends wheel rim, can produce want the wheel rim of any wide section.
