Description

The three-chip type rim structure

Technical field

The utility model relates to a kind of three-chip type rim structure, refers to that especially a kind of anter wheel frame and rear panel wheel frame are that integral type does not have join-forming, especially takes turns the jointless three-chip type rim structure of lip.

Background technology

The form of common wheel rim is broadly divided into three kinds of single piece type wheel rim, two-piece type wheel rim and three-chip type wheel rims.

At the three-chip type wheel rim, it is to be assembled by three-piece construction such as anter wheel frame, rear panel wheel frame and cards, therefore is referred to as the three-chip type wheel rim.

See also shown in Figure 1, tradition three-chip type wheel rim 40 existing major defects are that the anter wheel frame 41 and the wheel lip 43,44 of rear panel wheel frame 42 have seam 431,441, not only outward appearance is not attractive in appearance, have a strong impact on mechanical properties strength, impact resistance intensity, kinetic balance and the out of roundness of wheel rim simultaneously, and the infiltration oxidizability is serious.

Summary of the invention

The purpose of this utility model is to provide a kind of three-chip type rim structure, refers to that especially a kind of anter wheel frame and rear panel wheel frame are that integral type does not have join-forming, especially takes turns lip and does not have seam.

For reaching above-mentioned purpose, a kind of three-chip type rim structure of the utility model is characterized in that: comprise:

One anter wheel frame, it has an axle center, and this anter wheel frame has relative anter wheel lip and anter locking flange along this axis direction, and this anter wheel frame is that integral type does not have join-forming;

One rear panel wheel frame, it has an axle center, this rear panel wheel frame has relative rear panel wheel lip and rear panel locking flange along this axis direction, this rear panel wheel frame is and the coaxial setting of this anter wheel frame, this rear panel locking flange and this anter locking flange are adjacent, and this rear panel wheel frame is that integral type does not have join-forming; And

One card is to be arranged at this anter locking flange with respect to the one side that is provided with this rear panel locking flange.

The specific embodiment

See also Fig. 2 and shown in Figure 3, three-chip type rim structure provided by the utility model, it comprises anter wheel frame 10, rear panel wheel frame 20 and a card 30, this anter wheel frame 10 has an axle center C, this anter wheel frame 10 has relative anter wheel lip 11 and anter locking flange 12 along this axle center C direction, and this anter wheel frame 10 is that integral type does not have join-forming.

This rear panel wheel frame 20 also has an axle center, this rear panel wheel frame 20 is and these anter wheel frame 10 coaxial settings, this rear panel wheel frame 20 has relative rear panel wheel lip 21 and rear panel locking flange 22 along this axle center C direction, this rear panel locking flange 22 is adjacent with this anter locking flange 12, and this rear panel wheel frame 20 is that integral type does not have join-forming.

This card 30 is arranged at this anter locking flange 12 with respect to the one side that is provided with this rear panel locking flange 22, and this card 30, this anter locking flange 12 are to lock mutually with many bolts with this rear panel locking flange 22, and be not shown.

See also Fig. 3 and shown in Figure 4, because anter of the present utility model wheel frame 10 is that integral type does not have join-forming with rear panel wheel frame 20, so anter wheel lip 11 does not all have seam to exist with rear panel wheel lip 21.With the utility model and traditional three-chip type wheel rim relatively, it is as shown in the table to the utlity model has many advantages:

Project	?	This creation	Tradition three-chip type wheel rim
				1	Outward appearance	Integral-formed jointless	The wheel lip has seam
2	Mechanical properties strength	High	Low
				3	Impact resistance intensity	High	Low
4	Kinetic balance	High	Low
				5	Out of roundness	High	Low

6

Wheel lip infiltration oxidizability

Do not have

Seriously

In sum, the three-chip type rim structure that the utility model provides, because anter wheel frame and rear panel wheel frame are that integral type does not have join-forming, especially the utility model wheel lip does not have seam, compared to the three-chip type wheel rim that tradition wheel lip has seam, the utility model has better mechanical characteristics and appearance looks elegant degree really.

Only the above only is embodiment of the present utility model, when can not with the scope implemented of qualification the utility model.Promptly the equalization of being done according to the utility model claim generally changes and modifies, and all should still belong in the scope that the utility model patent contains.

Claims (2)
