The purpose of the utility model is to provide a hub for reducing wind resistance, which comprises a rim and a spoke, the spoke is connected with the rim, the rim comprises a front rim, the front rim is connected with the spoke, the rear of the front rim is connected with the rim groove, the rear of the rim groove is a support seat, the support seat is provided with a reinforcing rib, the rear of the support seat is connected with the rear rim, the wheel In the asymmetric design of spoke, the included angle between the two sides of the spoke and the central axis of the hub is different. The side with smaller included angle is the forward direction of the car, and the arc surface with smaller included angle is toward the forward direction of the car. The side with larger included angle has smaller wind resistance, which drives the air to flow in the direction of the inner brake disc, so as to achieve the effect of reducing the wind resistance.

一种降低风阻的轮毂
本技术涉及轮毂制造领域,特别涉及一种降低风阻的轮毂。
技术介绍
轮毂按材质一般可分为钢轮毂与合金轮毂。而合金轮毂具有重量轻,惯性阻力小,精度高,散热性好等特点;风阻是车辆行驶时来自空气是阻力,一般空气阻力有三种形式,第一为气流撞击车辆正面所产生的阻力;第二是摩擦阻力,空气划过车身一样会产生摩擦力;第三为外形阻力,一般来说,车辆高速行驶时,外形阻力是最主要的空气阻力来源,目前市场上的轮毂未做减少风阻的设计,使得汽车在高速行驶时受到空气阻力大,轮毂受到的压强也大,轮毂寿命受到影响。因此,我们有必要提供一种降低风阻的轮毂解决上述问题。
技术实现思路
本技术的目的是提供一种降低风阻的轮毂,用于汽车使用时减少空气阻力。本技术为解决其技术问题所采用的技术方案是,一种降低风阻的轮毂,包括轮辋和轮辐,所述轮辐连接轮辋,所述轮辋包括前轮缘,所述前轮缘与轮辐连接,所述前轮缘后方和轮辋凹槽相连,所述轮辋凹槽后方为支撑座,所述支撑座上设有加强筋,所述支撑座后方与后轮缘相连,所述轮辐非对称设 ...
