Description

一种无内胎汽车车轮轮辋A tubeless car wheel rim

（一）        技术领域  (1) Technical field

    本实用新型涉及一种汽车车轮，特别涉及一种无内胎汽车车轮轮辋。 The utility model relates to an automobile wheel, in particular to a tubeless automobile wheel rim.

（二）        背景技术  (2) Background Technology

    现在，一般无内胎汽车车轮轮辋轮缘为半圆弧，在车轮运动过程中，尤其是在高速运转、超载或者路况较差的情况下，随着轮胎内部气压的流动性，导致车轮轮辋两端（即两端轮缘）受力过载，超过钢材的屈服强度，就会导致轮缘变形。目前，普遍使用的改善方法是在普通的轮缘上加上一圈的加强筋，但普通安装加强筋，需通过焊接，不仅使车轮本身重量加重10％以上，而且轮缘整体外观凹凸不平，一点也不美观。因此，为解决这些问题而构想了一种无内胎车轮轮缘加强型车轮。 Now, the wheel rim of a tubeless car generally has a semi-circular arc. During the movement of the wheel, especially in the case of high-speed operation, overloading or poor road conditions, with the fluidity of the internal air pressure of the tire, the two ends of the wheel rim (That is, the rim at both ends) is overloaded and exceeds the yield strength of the steel, which will cause the rim to deform. At present, the commonly used improvement method is to add a circle of reinforcing ribs on the ordinary wheel rim, but the ordinary installation of reinforcing ribs requires welding, which not only increases the weight of the wheel itself by more than 10%, but also makes the overall appearance of the wheel rim uneven. Not aesthetically pleasing at all. Therefore, a tubeless wheel rim-reinforced wheel has been conceived to solve these problems.

（三）        发明内容  (3) Contents of the invention

    本实用新型为了弥补现有技术的不足，提供了一种抗压力强、使其外观优美的无内胎汽车车轮轮辋。 In order to make up for the deficiencies of the prior art, the utility model provides a tubeless automobile wheel rim with strong pressure resistance and beautiful appearance.

本实用新型是通过如下技术方案实现的：  The utility model is achieved through the following technical solutions:

一种无内胎汽车车轮轮辋，包括轮辐、轮缘、自轮缘向内延伸分别形成的第一胎圈座和第二胎圈座、第一胎圈座和第二胎圈座延伸连接形成的槽底，其特征是：所述轮缘为向内侧翻的圆环状，轮缘与第一胎圈座、第二胎圈座圆滑过渡贴合。 A tubeless automobile wheel rim, comprising a wheel spoke, a wheel rim, a first bead seat and a second bead seat extending inwardly from the wheel rim, and a first bead seat and a second bead seat formed by extending and connecting The bottom of the groove is characterized in that: the rim is in the shape of a ring turned inward, and the rim fits smoothly and transitionally with the first bead seat and the second bead seat.

所述第一胎圈座长度大于第二胎圈座的长度。  The first bead seat length is greater than the second bead seat length. the

所述轮辐环侧面开设有10个均匀分布的大减轻孔，垂直侧面开设有10个均匀分布的小减轻孔。  There are 10 evenly distributed large lightening holes on the side of the spoke ring, and 10 evenly distributed small lightening holes on the vertical side. the

所述轮缘、第一胎圈座、第二胎圈座、槽底、轮辐连接处均为弧形过渡连接。  The rim, the first bead seat, the second bead seat, the bottom of the groove, and the joints of the spokes are all arc-shaped transition connections. the

所述第一胎圈座与槽底连接处开设有气门嘴孔。  A valve hole is opened at the joint between the first bead seat and the groove bottom. the

本实用新型的有益效果是：相当于在普通车轮的基础上安装了一圈的加强筋，使轮缘其到加强作用，减少轮缘变形；可以使其与普通无内胎车轮通用；使得车轮轮辋整体外观更加优美。  The beneficial effects of the utility model are: it is equivalent to installing a circle of reinforcing ribs on the basis of ordinary wheels, so that the rims can be strengthened and the deformation of the rims can be reduced; it can be used in common with ordinary tubeless wheels; The overall appearance is more elegant. the

（五）        具体实施方式  (5) Specific implementation methods

附图为本实用新型的一种具体实施例。该实施例包括轮辐1、轮缘2、自轮缘2向内延伸分别形成的第一胎圈座3和第二胎圈座4、第一胎圈座3和第二胎圈座4延伸连接形成的槽底5，其特征是：所述轮缘2为向内侧翻的圆环状，轮缘2与第一胎圈座3、第二胎圈座4圆滑过渡贴合。所述第一胎圈座3长度大于第二胎圈座4的长度。所述轮辐1环侧面开设有10个均匀分布的大减轻孔6，垂直侧面开设有10个均匀分布的小减轻孔7。所述轮缘2、第一胎圈座3、第二胎圈座4、槽底5、轮辐1连接处均为弧形过渡连接。所述第一胎圈座3与槽底5连接处开设有气门嘴孔8。 Accompanying drawing is a kind of concrete embodiment of the utility model. This embodiment includes a spoke 1, a rim 2, a first bead seat 3 and a second bead seat 4 extending inwardly from the rim 2, and the first bead seat 3 and the second bead seat 4 are extended and connected. The formed groove bottom 5 is characterized in that: the rim 2 is in the shape of a ring turned inward, and the rim 2 fits with the first bead seat 3 and the second bead seat 4 in a smooth transition. The length of the first bead seat 3 is greater than the length of the second bead seat 4 . There are 10 evenly distributed large lightening holes 6 on the side of the spoke 1 ring, and 10 evenly distributed small lightening holes 7 on the vertical side. The joints of the rim 2, the first bead seat 3, the second bead seat 4, the groove bottom 5 and the spoke 1 are all arc-shaped transition connections. A valve hole 8 is opened at the junction of the first bead seat 3 and the groove bottom 5 .

采用本实用新型的一种无内胎汽车车轮轮辋，在下料过程中将轮缘2条料宽带加长15mm，通过传统辊压成型方式将两端轮缘2成型到产品的70﹪，再进行强力折弯旋压，使轮缘2与第一胎圈座3圆滑过渡贴合，成为圆环状，起到加强筋的作用。第一胎圈座3与第二胎圈座4连接形成槽底5，可以方便换胎。轮辐1上开设的大减轻孔6和小减轻孔7可减轻车轮重量，降低生产成本，还可起到平衡作用。第一胎圈座3与槽底5连接处开设有气门嘴孔8，方便给轮胎充气，还可使气门嘴孔8受到一定保护。   Adopting the rim of a tubeless automobile wheel of the utility model, during the blanking process, the width of the 2 strips of the rim is lengthened by 15 mm, and the rim 2 at both ends is formed to 70% of the product through the traditional roll forming method, and then it is folded by force The bending and spinning make the wheel rim 2 and the first bead seat 3 fit together in a smooth transition to form a circular ring, which acts as a reinforcing rib. The first bead seat 3 is connected with the second bead seat 4 to form a groove bottom 5, which can facilitate tire replacement. The large lightening hole 6 and the small lightening hole 7 provided on the wheel spoke 1 can reduce the weight of the wheel, reduce the production cost, and also play a balancing role. The joint between the first bead seat 3 and the groove bottom 5 is provided with a valve hole 8, which is convenient for inflating the tire and can also protect the valve hole 8 to a certain extent. the
