Description
Technical fields:
[0001] This utility model relates to the field of automotive parts, specifically to a type of automotive wheel hub steel. Background technology:
[0002] As a key component of automobiles, the performance of automotive wheel hubs directly affects driving safety and comfort. Existing automotive wheel hub steel profiles have several shortcomings: firstly, the lack of an effective positioning structure during assembly makes precise assembly of the steel profile with other wheel hub components difficult, affecting the overall balance of the wheel hub; secondly, poor shock absorption performance, directly transmitting vibrations from road impacts and reducing ride comfort; and thirdly, the lack of reinforcement measures in key stress-bearing areas makes them prone to fatigue deformation, shortening the wheel hub's service life. Therefore, developing a special-shaped steel structure for automotive wheel hubs that integrates positioning, shock absorption, and reinforcement functions is of great significance. To this end, this utility model proposes an automotive wheel hub steel profile to address the shortcomings and deficiencies of existing technologies. Utility Model Content:

A connecting portion is located in the middle, with one end of the connecting portion connected to the first bend, which bends and extends toward one side of the steel body. The other end of the connecting portion is connected to the second bend, which bends and extends toward the other side of the steel body. The steel body also includes a positioning and guiding structure, a shock-absorbing and buffering structure, a strength-enhancing structure, a heat dissipation structure, and an anti-corrosion strengthening layer.
[0006] Preferably, the positioning guide structure consists of at least two positioning bosses disposed on the outer side wall of the first bend, the positioning bosses being semi-cylindrical and spaced apart along the length of the steel body.
[0007] Preferably, the shock-absorbing and buffering structure comprises a cylindrical shock-absorbing cavity and elastic shock-absorbing columns embedded in the cylindrical shock-absorbing cavity. At least three cylindrical shock-absorbing cavities penetrating the width direction of the steel body are provided inside the connecting part, and the cylindrical shock-absorbing cavities are evenly distributed along the length direction of the steel body.
[0008] Preferably, each of the cylindrical damping cavities is fitted with an elastic damping column, which is made of polyurethane elastomer.
[0009] Preferably, the strength-enhancing structure is a reinforcing rib, and the inner sidewall of the second bend is provided with the reinforcing rib.
[0010] Preferably, the heat dissipation structure is a heat-conducting fin, which is disposed on the side wall of the second bend.
[0011] Preferably, the anti-corrosion reinforcement layer is a zinc-aluminum-magnesium alloy coating, and the outer surface of the steel body is coated with the zinc-aluminum-magnesium alloy coating.
[0012] The beneficial effects of this utility model are as follows: This utility model achieves precise assembly of the wheel hub assembly through a positioning boss, effectively absorbs road impacts with the built-in elastic damping cavity, and strengthens key stress-bearing parts through reinforcing ribs, extending the fatigue life of the wheel hub. The structure of this utility model integrates positioning, shock absorption, reinforcement, heat dissipation, and corrosion protection functions, comprehensively optimizing the overall performance of the wheel hub and improving vehicle driving safety and durability.
