汽车车架结构
本技术涉及汽车车架,尤其是涉及一种汽车车架结构。
技术介绍
对于越野SUV汽车来说,车架结构是其主要承载件,大多数部件及总成(如前后悬架、动力总成、转向系统及车身等)。因此,车架的强度及刚度是影响汽车稳定性的重要因素。车架一般由两根纵梁和若干横梁组成的框架结构,车架纵梁一般有若干U形钣金焊接而成,横梁为由截面呈U形结构的梁结构,在实际制造时,需要通过多个连接板将横梁和纵梁焊接或螺纹连接为一体,连接过程复杂繁琐,工作量大且效率低;同时对要求更高的车架,横梁上行通过需要设置有加强板,成本高。
技术实现思路
本技术目的在于提供一种强度高、结构简单、焊接效率高的汽车车架结构。为实现上述目的,本技术采取下述技术方案:本技术所述的汽车车架结构,包括由U形钣金焊接而成的左纵梁、右纵梁和间隔设置在所述左纵梁、右纵梁之间的横梁,所述横梁为截面呈圆形或椭圆形结构的管状结构,所述左纵梁内侧板和外侧板上对应开设有与横梁左部相配合的左安装孔,横梁左端通过所述左安装孔向左穿出左纵梁,横梁左端与左纵梁外侧板焊连为一体,所述右纵梁内侧板和外侧板上对应开设有与横梁右部相配合的右安装孔,横 ...
