Description

一种五辐高通风量大通风孔钢制车轮轮辐Five-spoke high ventilation large ventilated steel wheel spoke 技术领域Technical field
本发明涉及汽车零部件制造,特别涉及一种五辐高通风量大通风孔钢制车轮轮辐。The invention relates to the manufacture of automobile parts, in particular to a five-spoke high-ventilation large-ventilation steel wheel spoke.
背景技术Background technique
车轮是汽车重要的安全构件和外观件。作为安全构件,车轮是承受整车、乘客以及货物重量的载体,传递汽车加减速、转弯时的附加力,也承受路面飞石、凹坑的冲击,因此,车轮需要一定的强度刚度。车轮作为外观件,车轮的造型、风格将对整车风格、效果带来明显影响。车轮的美观程度直接影响着消费者对车型的喜好。因此,车轮既注重外观,也注重性能。The wheel is an important safety component and appearance part of the car. As a safety component, the wheel is the carrier that bears the weight of the whole vehicle, passengers and cargo. It transmits the acceleration and deceleration of the car, the additional force when turning, and also bears the impact of the flying stone and the pit. Therefore, the wheel needs a certain strength and rigidity. As the appearance of the wheel, the shape and style of the wheel will have a significant impact on the style and effect of the vehicle. The aesthetics of the wheels directly affect the consumer's preference for the model. Therefore, the wheel pays attention to both appearance and performance.
目前,车轮主要有钢制车轮和铝合金车轮两种,铝合金车轮由于其外表美观、重量轻,占有大部分乘用车车轮市场,而究其原因,主要为铝合金车轮主要为铸造生产,造型可以变化多样,各种复杂造型容易获得,而钢制车轮外观主要由轮辐决定,轮辐为冲压而成,变化较少,不易获得太复杂造型,同时,更为主要的是,开发形状复杂的、外观漂亮的轮辐时,极难同时保证车轮具有足够的强度、刚度。At present, the wheels mainly include steel wheels and aluminum alloy wheels. The aluminum alloy wheels occupy most of the passenger car wheel market due to their beautiful appearance and light weight. The reason is mainly that the aluminum alloy wheels are mainly for casting production. The shape can be varied, and various complex shapes are easily obtained. The appearance of the steel wheel is mainly determined by the spokes. The spokes are stamped, the change is less, and it is not easy to obtain too complicated shapes. At the same time, more importantly, the development of complex shapes When the spokes are beautiful in appearance, it is extremely difficult to ensure that the wheel has sufficient strength and rigidity.
传统的钢制车轮如图1、图3所示,其轮辐为等截面回转体零件,在回转面上分布数量不等的小通风孔,用于通风散热及减重,这种包裹得严实的结构相对于铝轮的筋条式结构(如图2所示)在外观上差异显著,由此市场表现显著差异铝轮,但钢制车轮在强度、成本、能耗上都优于铝合金车轮,如若能开发外观美观的、强度性能足够的钢制车轮,将能为钢制车轮获得更多市场,从而为汽车工业实现节能减排和降本。但国内目前尚无该类产品开发成功。The traditional steel wheel is shown in Fig. 1 and Fig. 3. The spokes are equal-section rotary parts, and a small number of small vent holes are distributed on the rotating surface for ventilation and heat reduction and weight reduction. Compared with the rib structure of the aluminum wheel (as shown in Figure 2), the structure is significantly different in appearance, so the market performance is significantly different from the aluminum wheel, but the steel wheel is superior to the aluminum alloy wheel in strength, cost and energy consumption. If you can develop steel wheels with beautiful appearance and sufficient strength and performance, you will be able to obtain more markets for steel wheels, thus achieving energy saving, emission reduction and cost reduction for the automotive industry. However, there is currently no such product development in China.
中国专利CN201010286771.3公开了一种采用钢管制作汽车车轮轮辐的方法,其采用钢管利用旋压工艺生产,在外观结构上并未有大的改进。中国专利CN200610068833.7公开了一种重载汽车高强度轮辐的加工方法,一种其是先加热再成形的卡车轮辐生产工艺,仍为传统的轮辐结构产品。 Chinese patent CN201010286771.3 discloses a method for manufacturing automobile wheel spokes by using steel pipes, which is produced by a spinning process using steel pipes, and has not been greatly improved in appearance structure. Chinese patent CN200610068833.7 discloses a processing method for high-intensity spokes of heavy-duty vehicles, which is a production process of card wheel spokes which are heated and reshaped first, and is still a traditional spoke structure product.
中国专利200680012150.8公开了一种装配式车辆的轮辐和包括这种轮辐的装配式车轮,该专利所提出车轮轮辐主要为安装面上至少有一个具有直外表面的肋,且并未明确是否为可采用冲压制造的钢制轮辐,也并未对轮辐更具体的结构特征、尺寸进行描述。同时,该具有直外表面的肋,其作用类似加强筋,以增加轮辐强度,弥补轮辐结构变化后的强度损失,但该肋具有直侧面,深度深,与螺丝孔过近,冲压成形难度极大,不易用冲压方式获得。即使获得了,也易因减薄量过大而致使疲劳强度降低,从而使产品性能存在极大风险。并且过高的肋占用了轮辐安装平面上方的空间,不利于轮辐的安装。Chinese Patent No. 200680012150.8 discloses a spoke of a prefabricated vehicle and an assembled wheel including the spoke. The wheel spoke of the patent proposes that the mounting surface has at least one rib having a straight outer surface, and it is not clear whether it is The steel spokes made by stamping do not describe the more specific structural features and dimensions of the spokes. At the same time, the rib having a straight outer surface functions like a reinforcing rib to increase the spoke strength and compensate for the strength loss after the spoke structure is changed, but the rib has a straight side, the depth is deep, and the screw hole is too close, and the stamping forming is extremely difficult. Large, not easy to obtain by stamping. Even if it is obtained, it is easy to reduce the fatigue strength due to the excessive amount of thinning, which poses a great risk to product performance. And the excessively high ribs occupy the space above the spoke mounting plane, which is not conducive to the installation of the spokes.
中国专利200580013225.X提出一种装配式车轮及其制造方法,其中轮辐主要特征为通风孔具有2个~3个窗口部分,且必须通过多次刺穿(冲孔)获得,对其他结构尺寸并未做出描述、要求。由于风孔需要2次甚至3次冲裁获得,增加了制造难度,使制造效率降低。且风孔各次冲裁间具有过度缺口,该缺口易成为疲劳裂纹源,不利于产品强度性能。Chinese Patent No. 200580013225.X proposes a fabricated wheel and a manufacturing method thereof, wherein the main feature of the spoke is that the vent hole has two to three window portions, and must be obtained by multiple piercing (punching) for other structural sizes. No descriptions or requirements have been made. Since the wind hole needs to be obtained twice or even three times, the manufacturing difficulty is increased and the manufacturing efficiency is lowered. Moreover, there are excessive gaps between the punching holes of the wind hole, and the notch is easy to be a source of fatigue crack, which is not conducive to product strength performance.
中国专利CN201080048554.9公开了一种汽车用轮辐,其在不使轮辐的原料板厚度与以往相比增加地、为了提高外观设计性而增大了装饰孔的情况下也可确保轮辐的强度和刚性的汽车用轮辐。该专利产品为在轮辐一周具有多层不同形状截面特征,能最大程度保证强度达到要求,但该类V形及近似方形的形状特征极难冲压成形获得,不利于实际制造。且该专利产品该类特征层次过多、且有一周波浪形,致使轮辐外形不干净利索,外观效果效果从而达不到最佳。Chinese Patent No. CN201080048554.9 discloses a spoke for an automobile which ensures the strength of the spokes without increasing the thickness of the raw material plate of the spokes and increasing the decorative hole for the purpose of improving the design. Rigid car spokes. The patented product has multiple layers of different shape cross-section features in the spokes, which can ensure the strength to meet the requirements to the greatest extent, but the V-shaped and approximately square shape features are extremely difficult to be formed by stamping, which is not conducive to actual manufacturing. Moreover, the patented product has too many levels of features and one-week wavy shape, so that the spoke shape is not clean and the appearance effect is not optimal.
中国专利CN200980143310.6公开了一种汽车用轮辐,其减少从装饰孔周缘弯曲部向车轮轴方向外侧突出的突出量而扩大车轮的规格的选择范围、并且确保轮辐的耐久性且能够使得辐条部与轮毂安装螺栓孔的个数与配置不会互相受到制约、轮毂螺母紧固作业变得容易、并且轮辐的成型容易的汽车用轮辐。但该产品为弥补结构变化后强度不足,在辐条中部设计有鼓起(凸起)特征以增加强度,而使得辐条底部型面不平顺,喷漆后将光顺性不好,有损辐条整体外观面表现。该专利产品通风孔边界与辐条侧壁顶部圆角相交,剖坏了圆角完整性,同样有损外观,且顶部圆角面在去除风孔后,易留下突出尖角,从而成为疲劳源,降低车轮性能。并且,该产品,为增加强度,设计了移动部,但该特征将使成形难度较大,增大 废品报废率,且由于与轮辋有部分间隙,在总成压配时易落入杂物,影响装配或带入涂装线而影响涂装质量。The Chinese patent CN200980143310.6 discloses a spoke for an automobile which reduces the amount of protrusion protruding from the curved portion of the decorative hole toward the outside in the direction of the wheel axis to expand the selection range of the specifications of the wheel, and ensures the durability of the spoke and enables the spoke portion The spokes for automobiles that are not compatible with the number and arrangement of the bolt holes of the hub, are easy to tighten the hub nut, and are easy to form the spokes. However, the product is insufficient in strength to compensate for the structural change, and a bulging (protruding) feature is designed in the middle of the spoke to increase the strength, so that the bottom surface of the spoke is not smooth, the smoothness after painting is not good, and the overall appearance of the spoke is damaged. Performance. The ventilating hole boundary of the patented product intersects with the rounded corner of the spoke sidewall, which cuts the integrity of the rounded corner and also damages the appearance. The top rounded surface is easy to leave a sharp corner after removing the wind hole, thus becoming a source of fatigue. , reducing wheel performance. Moreover, the product is designed to increase the strength, and the moving part is designed, but this feature makes the forming difficult and increases. Scrap scrap rate, and due to part of the gap with the rim, it is easy to fall into the debris during the assembly press, affecting the assembly or bringing into the coating line and affecting the quality of the coating.

The R rounded corners on both sides are tapered rounded corners, which gradually transition from the maximum rounded corner to the outer edge without the rounded corners. The radius of the rounded corner is 3~12mm.
五个大通风孔在保证强度性能基础上可尽可能大,以实现高通风量,在此,每个通风孔的面积>70cm2,总的通风面积为>350cm2The five large vents can be as large as possible to ensure high ventilation, where each vent has an area of >70 cm 2 and a total venting area of >350 cm 2 .

Moreover, in order to ensure that the mounting plane has a sufficient area, the groove section is gradually reduced in the radial direction from the inside to the outside, and the vertical axial section is U-shaped.

某畅销车型标配为铝轮,采用本发明提出的五幅高通风量大通风孔钢制车轮,材料为5.5mm DP600。One of the best-selling models is equipped with aluminum wheels. The five high-ventilation and large-ventilation steel wheels proposed by the present invention are made of 5.5mm DP600.
本发明轮辐使用材料为高强度钢板,其抗拉强度≥600MPa。为保证足够强度,厚度须为4.0mm~6.0mm。采用该轮辐的五幅高通风量大通风孔钢制车轮轮辐总重约4.5~6kg。The material used for the spoke of the invention is a high-strength steel plate, and the tensile strength is ≥600 MPa. In order to ensure sufficient strength, the thickness must be 4.0 mm to 6.0 mm. The five high-ventilation and large-ventilation steel wheel spokes using the spokes have a total weight of about 4.5 to 6 kg.
如图11所示,安装本发明五幅高通风量大通风孔新式钢制轮辐的全新车轮。图12为原标配铝合金车轮。As shown in Fig. 11, the five new wheels of the new high-ventilation ventilated new steel spokes of the present invention are installed. Figure 12 shows the original standard aluminum alloy wheels.
由图可见,本发明新式钢制车轮在外形表现上接近铝合金车轮,强度要求满足原设计要求,并且,经评估,主机厂采购成本将可下降1/3~1/2。It can be seen from the figure that the new steel wheel of the invention is close to the aluminum alloy wheel in the shape performance, the strength requirement satisfies the original design requirement, and, after evaluation, the procurement cost of the main engine factory can be reduced by 1/3 to 1/2.
随着中国汽车工业的竞争加剧,对性能、降低、节能的要求越来越高,而目前国内乘用车市场,尽管钢制车轮性能表现、采购成本、制造所需能耗、回收利用等方面都优于铝合金车轮,但钢制车轮由于制造工艺及疲劳 要求的原因,极难达到铝合金车轮的美观、易变程度,钢制车轮市场一直在缩小。铝合金靠其美观多变的造型,占据了大部分市场,因此外形能媲美铝合金车轮的钢制车轮的开发成为了钢制车轮市场开拓的瓶颈。本发明之前,国内尚未有相关的钢制车轮产品开发成功。As the competition in China's auto industry intensifies, the requirements for performance, reduction, and energy conservation are getting higher and higher. At present, the domestic passenger car market, despite the performance of steel wheels, procurement costs, energy consumption for manufacturing, recycling, etc. Both are better than aluminum alloy wheels, but steel wheels are due to manufacturing process and fatigue. The reason for the request is extremely difficult to achieve the aesthetic and variability of the aluminum alloy wheels, and the steel wheel market has been shrinking. Aluminum alloys occupy most of the market by virtue of their beautiful and changeable shape. Therefore, the development of steel wheels with the shape comparable to aluminum alloy wheels has become the bottleneck for the development of the steel wheel market. Prior to the present invention, there was no relevant steel wheel product development in China.
通过采用本发明钢制车轮轮辐的钢制车轮,外形能接近铝合车轮,且仍能满足车轮疲劳等性能要求,由此可用于替换铝合金车轮,从而可协助主机厂实现性能提高、采购成本降低、制造消耗能耗降低,最终实现节能环保且产品更优价钱更廉。 By adopting the steel wheel of the steel wheel spoke of the invention, the shape can be close to the aluminum alloy wheel, and can still meet the performance requirements of wheel fatigue, thereby being able to replace the aluminum alloy wheel, thereby assisting the main engine factory to achieve performance improvement and procurement cost. Reduced, reduced manufacturing energy consumption, and ultimately achieved energy saving and environmental protection, and the products are better and cheaper.
