Abstract
The utility model relates to the technical field of automobile parts, in particular to a wheel flange plate with a notch structure. The utility model adopts the following technical scheme: the discontinuous cylindrical surface is arranged at the matching part of the flange shaft and the rim, the discontinuous cylindrical surface is uniformly distributed on the circumference and can be designed into three uniformly distributed grooves, the included angle of the circumference of each groove is 50-70, but the included angle is not limited to trisection and can be more than trisection, and the static unbalance of the flange shaft can be reduced due to the uniform distribution of the grooves. According to the technical scheme, the flange shaft adopts a circumferential notch design, so that the joint area of the wheel rim and the flange shaft is reduced, the disassembling force during wheel maintenance is reduced, and the wheel rim and the flange shaft are easy to disassemble during maintenance after being rusted; according to the technical scheme, the gap design further reduces the weight of the wheel flange plate, meets the requirement of light weight of a vehicle, reduces the material usage and saves the cost.
Description
Technical Field
The utility model relates to the field of automobile parts, in particular to a wheel flange plate with a notch structure.
Background
In the prior art, referring to fig. 1-2, a hub bearing is connected with a wheel through a wheel flange, the wheel rim and a brake disc are connected together through wheel bolts, and a wheel flange shaft needs to extend into a matching hole of the wheel rim to facilitate the installation of the wheel. Generally, the fitting part of the wheel flange and the wheel rim is a complete cylindrical surface. The cylindrical surface can guide the installation of the wheels and can play a role in auxiliary support when the wheels are stressed.
However, the above technique has the following problems:
in the prior art, the matching part of the wheel flange plate and the rim adopts clearance fit, the matching part of the flange is a complete cylindrical surface, and after the wheel flange plate and the rim are used for a period of time, the matching part of the flange shaft and the rim is easy to generate phenomena of electrochemical corrosion, rusting and the like, so that the wheel is difficult to disassemble during maintenance;
the stress of the wheel flange and the wheel rim matching part is a low stress area in the prior art, and the current design is not beneficial to the light weight of the automobile and the improvement of the utilization rate of raw materials.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art and provides a wheel flange plate with a notch structure.
The purpose of the utility model is achieved by the following technical scheme: the wheel flange plate with the notch structure has the advantages that the discontinuous cylindrical surface is arranged at the matching part of the flange shaft and the rim, the discontinuous cylindrical surface is uniformly distributed on the circumference and can be designed into three uniformly distributed grooves, the included angle of the circumference of each groove is 50-70, but not limited to trisection, the groove can be divided into more parts, and the static unbalance of the flange shaft can be reduced due to the uniform distribution of the grooves.
The utility model has the beneficial effects that:
according to the technical scheme, the flange shaft adopts a circumferential notch design, so that the joint area of the wheel rim and the flange shaft is reduced, the disassembling force during wheel maintenance is reduced, and the wheel rim and the flange shaft are easy to disassemble during maintenance after being rusted;
according to the technical scheme, the gap design further reduces the weight of the wheel flange plate, meets the requirement of light weight of a vehicle, reduces the material usage and saves the cost.

Detailed Description
The utility model will be described in detail below with reference to the following drawings:
example (b): as shown in fig. 3-6, the gap structure is a wheel flange, which is applied to a wheel bearing flange at a wheel. It includes wheel flange dish main part 4, wheel flange dish main part 4 is equipped with flange axle 5, and flange axle 5 presents discontinuous face of cylinder with rim cooperation department, and this discontinuous face of cylinder is a plurality of recesses 6 of evenly distributed design on the circumference, can design into three equipartition recess 6, and 6 circumference contained angles of every recess can be at 50 ~ 70, but not being limited to trisection, can divide by many, and 6 quantity of the shoulder arm recess is no longer than five at most, and 6 equipartitions of recess can reduce the static unbalance amount of flange axle 5.
It should be understood that equivalent alterations and modifications of the technical solution and the inventive concept of the present invention by those skilled in the art should fall within the scope of the appended claims.
Claims (3)
1. The utility model provides a breach structure wheel flange dish which characterized in that: including wheel flange plate body (4), wheel flange plate body (4) are equipped with flange axle (5), flange axle (5) and wheel rim cooperation department present discontinuous face of cylinder, and discontinuous face of cylinder is evenly distributed on the circumference and is a plurality of recesses (6), and recess (6) quantity is five at most.
2. The notched structure wheel flange of claim 1, wherein: the number of the grooves (6) is three or five.
