Abstract

The invention relates to a reinforced wheel rim structure, comprising a rim and a spoke welded on the inner ring wall of the rim. The reinforced wheel rim structure is characterized in that the spoke consists of three parts which are respectively a planar disc part, a cross bar ring part and an inclined part, wherein the planar disc part is located in the middle of the spoke and is used for being connected with the rotation shaft of a car; the cross bar ring part is located in the inner ring wall of the rim and is used for realizing welding connection; the inclined part is located between the ring part and the disc part; a connection through hole for realizing connection with the rotation shaft of the car is arranged in the middle of the disc part; six bolt fixing holes are uniformly distributed along the circumference of the disc part outside the connection through hole; twelve air holes are uniformly distributed in the circumference of the upper edge of the inclined part; the thickness of the inclined part is increased from the connection area with the disc part to the connection area with the ring part; multiple arc concave-convex surfaces are arranged on the rim; a through hole is formed in the disc part between the connection through hole and the bolt fixing holes; a through hole is formed in one convex surface of the rim. The reinforced wheel rim structure has a reasonable structure, the bearing capacity is strong, and the overload requirement of the vehicle in certain conditions can be met, thus the potential safety hazard is reduced.

Description

A kind of enhanced type wheel rim flange ring structure

Technical field

Patent of the present invention relates to a kind of enhanced type wheel rim flange ring structure, belongs to auto parts and components field.

Background technology

Wheel rim flange ring is most important for car, a good wheel rim flange ring of performance can promote the load carrying ability of automobile, there is overweight carrying in existing vehicle occasional, and that current vehicle steel ring bears the ability of overload is also not strong, be easy to cause safety misadventure, and sometimes have to can bear within a certain period of time the impact of overload.。Therefore the load-carrying capacity that, possesses certain limit for support vehicles is the object that the present invention studies.

Summary of the invention

In view of the deficiencies in the prior art, the invention provides a kind of enhanced type wheel rim flange ring structure, contribute to solve existing vehicle steel ring in the time having to overload and cannot bear overload and easily cause the problems such as safety misadventure.

Technical program of the present invention lies in:

A kind of strenghthened type wheel steel ring structure, comprise wheel rim and be welded on the spoke on wheel rim inner ring wall, it is characterized in that: described spoke forms by three sections, be respectively be positioned at spoke middle part in order to connect the plane round plate of automobile turning cylinder, be positioned at the horizontal stripe shape annulus portion being welded to connect in order to realization on wheel rim inner ring wall, rake between annulus portion and round plate, the middle part of described round plate is provided with realizes the connecting through hole being connected with automobile turning cylinder, the round plate that is positioned at connecting through hole outside is uniformly distributed with 6 bolt fixed orifices along the circumference, on described rake, be uniformly distributed with 12 wind holes along the circumference, the thickness of described rake by with round plate join domain thickening to annulus portion join domain, described wheel rim is provided with some arc male and fomale(M&F)s, round plate between described connecting through hole and bolt fixed orifice is provided with 1 through hole, the convex surface of one of them of described wheel rim is provided with a through hole.

Wherein, in the spoke constituent of described steel ring, carbon is controlled at 0.10%-0.25%, and silicon is controlled at 0.10%-0.55%, and phosphorus is less than or equal to 0.05%, and manganese is controlled at 0.5%-1.5%; And the yield strength of spoke is greater than and equals 250MPa, tensile strength is controlled at and is more than or equal to 480MPa, and elongation after fracture is controlled at and is more than or equal to 25%, and section yield is greater than 35%, and impacts and be greater than 20J under-40 degree low temperature.The invention has the advantages that: the present invention constructs rationally, and bearing capacity is strong, can meet vehicle overload needs under specific circumstances, thereby reduce potential safety hazard.

Brief description of the drawings

The main TV structure schematic diagram of Fig. 1 embodiment of the present invention.

Fig. 2 is that the A-A of Fig. 1 is to sectional structure schematic diagram.

Detailed description of the invention

For above-mentioned feature and advantage of the present invention can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.

With reference to figure 1, Fig. 2, the present invention relates to a kind of enhanced type wheel rim flange ring structure, comprise wheel rim 1 and be welded on the spoke 2 on wheel rim inner ring wall, described spoke is by casting one-shot forming, the process of the welding in the middle of having saved, ensured that intensity has also reduced stress and concentrated, but still can be divided into by three sections and represent, specifically be respectively be positioned at spoke middle part in order to connect the plane round plate 2-1 of automobile turning cylinder, be positioned at the horizontal stripe shape annulus 2-2 of portion being welded to connect in order to realization on wheel rim inner ring wall, rake 2-3 between annulus portion and round plate, the middle part of described round plate is provided with realizes the connecting through hole 4 being connected with automobile turning cylinder, the round plate that is positioned at connecting through hole outside is uniformly distributed with 6 bolt fixed orifices 5 along the circumference, on described rake, be uniformly distributed with 12 wind holes 6 along the circumference, the thickness of described rake by with round plate join domain thickening to annulus portion join domain, arrange by above-mentioned wind hole number, and the variation in thickness of rake, can promote the intensity of spoke.

For ensure tire can relatively goodly be attached to wheel rim and, and can also bear the impact of overload, on above-mentioned wheel rim, be provided with some arc male and fomale(M&F)s 7, and be provided with a through hole 8 on one of them convex surface of wheel rim.

In order further to promote Steel Wheel Intension, on the round plate between above-mentioned connecting through hole and bolt fixed orifice, be provided with 1 through hole 3.

Under said structure, also need to make in the spoke constituent of steel ring, carbon is controlled at 0.10%-0.25%, and silicon is controlled at 0.10%-0.55%, and phosphorus is less than or equal to 0.05%, and manganese is controlled at 0.5%-1.5%; And the yield strength of spoke is greater than and equals 250MPa, tensile strength is controlled at and is more than or equal to 480MPa, and elongation after fracture is controlled at and is more than or equal to 25%, and section yield is greater than 35%, and impacts and be greater than 20J under-40 degree low temperature.

The present invention adopts said structure characteristic Design, can support vehicles safety in certain overload situation, utilize the integrated casting of spoke, reduce the subregion stress that welding causes and concentrate, thereby ensure driving safety.

The foregoing is only preferred embodiment of the present invention, all equalizations of doing according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
