技术领域 Technical field
本发明涉及汽车制造领域，尤其是指一种用于客车骨架结构的车 架部件。 背景技术  The present invention relates to the field of automobile manufacturing, and more particularly to a frame member for a passenger car skeleton structure. Background technique
现有的客车骨架结构形式主要有三种：  There are three main types of existing bus skeleton structures:
第一种， 非^ ^载式。 汽车有刚性车架， 又称底盘大梁架。 车身本 体悬置于车架上， 用弹性元件联接， 主要靠车架承重， 车身不参与受 力。 这种非承载式车身比较笨重， 质量大， 汽车质心高， 高速行驶稳 定性较差。  The first type is not ^^. The car has a rigid frame, also known as a chassis frame. The body of the body is suspended on the frame and connected by elastic elements. The main body is supported by the frame and the body does not participate in the load. This non-loaded body is bulky, of high quality, with high car center of mass and poor stability at high speeds.
第二种， 半承载式。 半承载式车身的汽车没有刚性大梁架， 只是 加强了前围， 侧围， 后围， 底架等部位， 车身和底架共同组成了车身 本体的刚性空间结构。 这种半承载式， 车身只是部分参与受力， 质量 比非承载式车身稍小。  Second, semi-loaded. The semi-loaded body car has no rigid girders, but only the front wall, side wall, rear wall, and underframe are strengthened. The body and the bottom frame together form a rigid space structure of the body body. This semi-loaded, body is only partially involved in the force, the quality is slightly smaller than the non-loaded body.
第三种， 采用巨型钢管焊接而成的全承载式车身结构。 该全承载 式车身结构虽然质量比前两种小，但还不能有效的大幅度降低车身重 量。  The third type is a full-loaded body structure welded by a giant steel pipe. Although the mass of the full-loaded body structure is smaller than the first two, it cannot effectively reduce the weight of the vehicle.
以上三种结构均为钢制结构， 整车重量大， 导致承载能力下降， 客车能耗偏高，再有钢骨架容易生锈， 即使磷化处理过的骨架寿命也 不过 8年左右， 而且不能回收利用。 磷化液中的磷是一种剧毒物质， 以及矩型钢管上所喷的防锈漆， 均严重污染环境。  The above three structures are all made of steel. The weight of the whole vehicle is large, resulting in a decrease in load carrying capacity. The energy consumption of passenger cars is high, and the steel skeleton is easy to rust. Even the life of the phosphated skeleton is only about 8 years, and it cannot recycle and re-use. Phosphorus in the phosphating solution is a highly toxic substance, and the anti-rust paint sprayed on the rectangular steel pipe is seriously polluting the environment.

In Fig. 3, the frame member of the present invention is used as a top cover beam and a top cover longitudinal beam in the overall structure of the frame, and is riveted by a mid-corner code. Specifically, the top cover beam dl is riveted to the first roof vertical beam d2 by the first middle corner code j1 and the second middle corner code j 2, wherein the first middle corner code j1 and the second middle corner code j 2 are one side The two sides of the groove structure respectively with the first roof rail d2 are riveted together by rivets, the other side of the first middle corner code jl and the second middle corner code j 2 and one side of the top cover beam d1 The sides are riveted together by rivets; the top cover beam d2 is riveted to the second top cover stringer d3 by a third middle corner code j 3 and a fourth middle corner code j4, wherein the third middle corner code j 3 and the fourth middle corner code One side of j 4 is riveted together with two sides of the groove structure of the second top cover stringer d3, and the other side and top of the third middle corner code j 3 and the fourth middle corner code j4 The other side of the cover beam d1 is symmetrical with respect to the riveting positions of the first mid-corner code j1 and the second mid-corner code j 2 and is riveted together by rivets.
图 3连接结构中的中角码横截面结构如图 4所示为 "L" 型直角 结构， 其内角以及两边的边缘处采用圓角结构， 避免了局部应力过大 而使中角码产生裂纹。 本发明与目前客车骨架结构中所使用的钢制部件相比，具有重量 轻、 寿命长的特点， 并且本发明的车架部件的强度不低于钢制部件， 举例说明: ¾口下：  The cross-sectional structure of the middle corner code in the joint structure of Fig. 3 is shown as "L" type right angle structure, and the inner corner and the edges of the two sides are rounded to avoid excessive local stress and crack in the middle corner code. . Compared with the steel components used in the skeleton structure of the current passenger car, the invention has the characteristics of light weight and long service life, and the strength of the frame component of the invention is not lower than that of the steel component. For example: 3⁄4 mouth:
目前， 普通钢骨架客车顶盖横梁及顶盖纵梁一般为 30匪 X 50匪 x l. 75匪矩形钢管， 其 1 m长的重量为 2. 1 kg, 其到屈服极限时的 抗拉力为  At present, the ordinary steel skeleton passenger car roof beam and the roof longitudinal beam are generally 30匪X 50匪x l. 75匪 rectangular steel pipe, the weight of 1 m long is 2.1 kg, and its tensile strength to the yield limit. For
F=Rm X S  F=Rm X S
其中 Rm是抗拉强度， 单位是 MPa， S为矩形钢管截面积， 单位是平方 米。 型号为 Q235的矩形钢管抗拉强度 Rm为 415MPa , 矩形钢管的截 面积 S=0. 00026775 m% 所以可得抗拉力为 Where Rm is the tensile strength, the unit is MPa, S is the cross-sectional area of the rectangular steel pipe, and the unit is square meters. The tensile strength Rm of the rectangular steel pipe of model Q235 is 415MPa, and the cross-sectional area of the rectangular steel pipe is S=0. 00026775 m%, so the tensile strength is obtained.
F=Rm x S=111116 N。 若采用本发明车架部件作为顶盖横梁及纵梁， 当其截面积F=Rm x S=111116 N. If the frame member of the present invention is used as a cover beam and a longitudinal beam, when the cross-sectional area thereof
S=0. 000542 m2时， 采用 6082T6型铝合金，其抗拉强度为 Rm=310 MPa, 则可得出其抗拉力 When S=0.000542 m 2 , the 6082T6 type aluminum alloy is used, and its tensile strength is Rm=310 MPa, then the tensile strength can be obtained.
F=Rm x S=168175 N  F=Rm x S=168175 N
而其 1 m长的重量为  And its weight of 1 m is
G=2. 7 g/cm3 x 542 cm3=l. 46 kg 由此可知，采用此种铝合金作为顶横梁和顶纵梁到屈服极限时的 抗拉力高于 30mm X 50mm X 1. 75匪矩形钢管， 而重量却只有矩形钢管 的 69. 5%。 因此使用本发明的铝型材部件其在大大减轻重量的同时， 能够达到现有骨架为矩形钢管结构的客车的强度， 使客车的自重减 轻，减少能耗， 并且不会生锈，相比钢制部件，其使用寿命大大延长, 可达 25年。 以上所述仅为本发明的较佳实施例， 并不用以限制本发明， 凡在 本发明的精神和原则之内， 所作的任何修改、 等同替换、 改进等， 均 应包含在本发明的保护范围之内。 G=2. 7 g/cm 3 x 542 cm 3 =l. 46 kg It can be seen that the tensile strength of the aluminum alloy as the top beam and the top longitudinal beam to the yield limit is higher than 30 mm X 50 mm X 1. 75 匪 rectangular steel pipe, and the weight is only 69.5% of the rectangular steel pipe. Therefore, the aluminum profile member of the present invention can greatly reduce the weight, and can achieve the strength of a passenger car having a rectangular steel pipe structure, reduce the weight of the passenger car, reduce energy consumption, and prevent rust, compared with steel. Parts have a long service life of up to 25 years. The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., which are within the spirit and scope of the present invention, should be included in the protection of the present invention. Within the scope.
