Description

一种汽车用轻量化车轮  Lightweight wheel for automobile
技术领域 本实用新型涉及一种汽车用轻量化车轮，特别涉及一种载重汽车、 客车等大型车辆的车轮。 它是对现有汽车的车轮所作出的新的改进。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lightweight wheel for an automobile, and more particularly to a wheel of a large vehicle such as a truck or a passenger car. It is a new improvement to the wheels of existing cars.
背景技术 车轮是车辆行走时传递车身与路面的力的支撑件，一般由轮辋和 轮辐组成， 而轮辐又是保证车轮承受支撑载荷时的主要受力件， 尤其 是载重汽车、 客车等大型车辆， 对车轮轮辐的承载力、 安全性等要求 更高。 因此， 为了保证足够的承载力， 轮辐整体的厚度往往采用较厚 的钢板制造。现有载重车的车轮轮辐均采用钢板压力成型或旋压制造 而成，仅轮辐的重量就占到整个车轮重量的 50%左右。在节能减排日 益严峻、石油资源日益紧张的现代社会， 车辆的轻量化必然是汽车发 展的趋势。 据研究车辆自重减轻 10%, 可降低油耗 5%-8% (摘自中 国汽车导讯杂志）。 BACKGROUND OF THE INVENTION A wheel is a support member for transmitting a force between a vehicle body and a road surface when the vehicle is traveling, and is generally composed of a rim and a spoke, and the spoke is a main force member for ensuring that the wheel is subjected to a supporting load, especially a large vehicle such as a truck or a passenger car. The bearing capacity and safety of the wheel spokes are more demanding. Therefore, in order to ensure sufficient bearing capacity, the thickness of the entire spoke is often made of a thick steel plate. The wheel spokes of existing trucks are made by pressure forming or spinning of steel plates, and only the weight of the spokes accounts for about 50% of the weight of the entire wheel. In a modern society where energy conservation and emission reduction are increasingly serious and oil resources are increasingly strained, the weight reduction of vehicles is inevitably a trend of automobile development. According to research, the vehicle's own weight is reduced by 10%, which can reduce fuel consumption by 5%-8% (extracted from China Automotive News Magazine).

Therefore, the original spoke cone profile wall thickness can be reduced by 30%, and the weight can be reduced by about 30%. According to each wheel, it can be reduced by 5Kg, which is calculated by 25 rounds of large trucks. The weight of the whole vehicle is obvious, and the weight can be reduced by 125Kg.

图中： 1轮辋， 2轮辐， 2-1安装面， 2-2螺栓孔， 2-3车轴孔， 2-4 风孔， 2-5加强筋， 3焊接口， 4内凹部， 5凸峰 。 具体实施方式 参见图 1和图 2， 本实用新型汽车用轻量化车轮结构是： 它由轮 辋 1和轮辐 2组成。轮辋 1为两头大中间小的中空环形体结构， 与现 有的车轮轮辋形状相同， 其形状符合 GB/T3487的任何一种汽车轮辋 断面的环形结构； 所述轮辐 2为锥台筒形， 其大直径端为一敞口， 小 直径端为环形安装面 2-1。 轮辐 2的大直径敞口端扣在轮辋 1内， 和 轮辋 1焊接为一体。 图 1、 2中， 轮辐 2和轮辋 1通过焊接口 3焊接 在一起组成车轮。 轮辐 2的安装面 2-1上均布有螺栓孔 2-2， 用于车 轮整体的固定。 安装面 2-1的中心是车轴孔 2-3。 在轮辐 2的锥形体 轮廓上均布有风孔 2-4， 风孔 2-4依车轮的大小， 其设计的数量不等。 风孔 2-4的设计不但可以减轻轮辐的重量， 而且起着对轮辐 2降温的 作用。 风孔 2-4可以是圆形孔、 椭圆形孔或其他形状的孔。 作为本实 用新型的较佳实施例， 图 1中的风孔 2-4是椭圆形孔， 椭圆形孔的长 方向与轮辐中心轴线的方向垂直。 在风孔 2-4与相邻风孔 2-4之间区 域的加强筋 2-5形成统一的外凸或统一的内凹状， 使整体的锥形体轮 廓形成了凹凸相间形状， 即整体的锥形体轮廓形成为： 当加强筋 2-5 都向外凸时， 风孔 2-4周边区域则相对于加强筋 2-5呈向内凹的凹凸 状结构； 或者是当加强筋 2-5都向内凹时， 风孔 2-4周边区域则相对 于加强筋 2-5呈向外凸的凹凸状结构； 以此增强了该类型轮辐 2整体 强度。 由于轮辐 2整体形成的凹凸状构造， 车轮轮辐 2的厚度就可以 做得相对较薄， 车轮轮辐 2的重量被大大减轻， 并且承载力不会受到 影响。 同时， 风孔 2-4也可以适当做得较大， 使风孔 2-4的孔缘紧邻 两侧的加强筋 2-5， 进一步减轻了轮辐的重量。 从而减轻整个车轮的 重量。 In the picture: 1 rim, 2 spokes, 2-1 mounting surface, 2-2 bolt holes, 2-3 axle holes, 2-4 air holes, 2-5 stiffeners, 3 welded joints, 4 recesses, 5 peaks . DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to Figures 1 and 2, the lightweight wheel structure for an automobile of the present invention is: It is composed of a rim 1 and a spoke 2. The rim 1 is a large hollow intermediate ring structure with two large and small intermediate shapes, and has the same shape as the existing wheel rim, and the shape conforms to the annular structure of any automobile rim section of GB/T3487; the spoke 2 is a cone-shaped cylinder shape, The large diameter end is an open and the small diameter end is an annular mounting surface 2-1. The large-diameter open end of the spoke 2 is fastened in the rim 1 and welded integrally with the rim 1. In Figs. 1, 2, the spoke 2 and the rim 1 are welded together by the welded joint 3 to form a wheel. The mounting surface 2-1 of the spoke 2 is uniformly provided with bolt holes 2-2 for fixing the entire wheel. The center of the mounting surface 2-1 is the axle hole 2-3. Wind holes 2-4 are uniformly distributed on the contour of the cone of the spoke 2, and the number of the wind holes 2-4 varies depending on the size of the wheel. The design of the air holes 2-4 not only reduces the weight of the spokes, but also acts to cool the spokes 2. The air holes 2-4 may be circular holes, elliptical holes or other shaped holes. As a preferred embodiment of the present invention, the air holes 2-4 in Fig. 1 are elliptical holes whose longitudinal direction is perpendicular to the direction of the central axis of the spoke. The reinforcing ribs 2-5 in the region between the air holes 2-4 and the adjacent air holes 2-4 form a uniform convex or uniform concave shape, so that the overall contour of the cone forms an uneven shape, that is, an overall cone The contour of the body is formed as follows: when the reinforcing ribs 2-5 are outwardly convex, the peripheral portion of the air hole 2-4 is inwardly concave and concave with respect to the reinforcing rib 2-5; or when the reinforcing ribs 2-5 are When recessed inwardly, the peripheral portion of the air hole 2-4 has an outwardly convex concave-convex structure with respect to the reinforcing rib 2-5; thereby enhancing the overall strength of the spoke 2 of this type. Due to the concavo-convex structure integrally formed by the spokes 2, the thickness of the wheel spokes 2 can be made relatively thin, the weight of the wheel spokes 2 is greatly reduced, and the bearing capacity is not affected. At the same time, the air holes 2-4 can also be made larger, so that the hole edges of the air holes 2-4 are adjacent to the reinforcing ribs 2-5 on both sides, further reducing the weight of the spokes. Thereby reducing the entire wheel Weight.
本实用新型较佳的实施例， 在风孔 2-4与相邻风孔 2-4之间区域 的加强筋 2-5形成统一的内凹状， 风孔外周侧设有一圈与风孔形状相 对应的内凹部 4， 以此增强了该类型轮辐 2整体强度。 由于轮辐 2整 体形成的凹凸状构造， 车轮轮辐 2的厚度就可以做得相对较薄， 在承 载力相同的情况下， 车轮轮辐 2的重量大大减轻， 并且有利于防止应 另外， 在该较佳实施例中， 轮辋 1的单侧或两侧胎圈座部位上设 有凸峰 5， 设置凸峰 5， 一方面， 有利于防止车辆在转向时， 轮胎受 到侧向力的作用，胎体容易脱离胎圈座而滑移到槽底，造成轮胎漏气； 另一方面， 有利于进一步加强胎圈座的强度， 使轮辋不容易变形。  In a preferred embodiment of the present invention, the reinforcing ribs 2-5 in the region between the air holes 2-4 and the adjacent air holes 2-4 form a uniform concave shape, and the outer peripheral side of the air hole is provided with a ring shape and a wind hole shape. Corresponding recesses 4, which enhance the overall strength of this type of spoke 2. Due to the concavo-convex structure integrally formed by the spokes 2, the thickness of the wheel spokes 2 can be made relatively thin. In the case of the same bearing capacity, the weight of the wheel spokes 2 is greatly reduced, and it is advantageous to prevent the other from being better. In the embodiment, the one side or the two side bead seat portions of the rim 1 are provided with a peak 5 and a peak 5 is provided. On the one hand, it is advantageous to prevent the tire from being subjected to the lateral force when the vehicle is turning, and the carcass is easy. It slips out of the bead seat and slips to the bottom of the groove, causing the tire to leak; on the other hand, it is beneficial to further strengthen the strength of the bead seat, so that the rim is not easily deformed.
综上所述， 本实用新型车轮设计特点在于， 利用轮辐的风孔与风 孔之间区域的凹凸状结构起到强度提高的作用，从而可减少轮辐的用 材厚度， 大大减轻了车轮的重量。 经试验， 同样条件的钢板制造的轮 辐， 轮辐锥形体轮廓改为内凹或者外凸结构状态， 其强度高于非内凹 或者外凸结构状态的车轮轮辐强度，其径向疲劳强度比结构为非内凹 或者外凸结构状态轮辐的车轮提高了约 40%左右，弯曲疲劳强度提高 了约 30%左右。因此原有轮辐锥形体轮廓壁厚可降低 30%,重量可降 低 30%左右。 按每个车轮可降低 5Kg,—辆大货车 25个轮计算， 整车 轻量化明显， 可降低自重 125Kg， 长期使用效益可观， 对轮辐生产企 业来讲又节约了原材料。  In summary, the wheel design of the present invention is characterized in that the uneven structure of the region between the wind hole and the air hole of the spoke is used to improve the strength, thereby reducing the thickness of the material of the spoke and greatly reducing the weight of the wheel. After testing, the spokes made of the same condition steel plate, the conical cone profile is changed to the concave or convex structure state, and its strength is higher than the wheel spoke strength of the non-concave or convex structure state, and the radial fatigue strength ratio structure is The wheels of the non-concave or convex structural state spokes are increased by about 40%, and the bending fatigue strength is increased by about 30%. Therefore, the original spoke cone profile wall thickness can be reduced by 30%, and the weight can be reduced by about 30%. According to each wheel, it can be reduced by 5Kg, which is calculated by 25 large trucks. The weight of the whole vehicle is obvious, and the weight can be reduced by 125Kg. The long-term use efficiency is considerable, and the raw materials are saved for the spoke production enterprises.
