Description
技术领域technical field
本实用新型涉及一种轻量化载货汽车车架前端用横梁，属于汽车零部件技术领域。The utility model relates to a crossbeam for the front end of a lightweight truck frame, which belongs to the technical field of auto parts.
背景技术Background technique
目前，现有的重型汽车车架横梁总成主要为槽型横梁两端与U型连接板焊接而成的刚性横梁结构，或者槽型横梁与L型连接板用螺栓连接的柔性横梁结构。横梁总成在使用过程中主要承受扭矩和弯曲等交变负荷、冲击负荷。在载重越重，路况越恶劣的情况下，要求横梁总成有较好的刚性、强度、抗变形能力等综合机械性能越高。否则，横梁在使用过程中易变形、裂纹。现有的刚性横梁结构在承受扭转力时变形量小易变形断裂，而柔性横梁结构的具有很好的变形量，但是刚性低强度低，无法满足载重要求。并且现有的两种横梁结构自重大，无法满足轻量化载货汽车设计的要求。At present, the existing heavy-duty vehicle frame beam assembly is mainly a rigid beam structure in which both ends of the channel beam are welded to a U-shaped connecting plate, or a flexible beam structure in which the channel beam and the L-shaped connecting plate are connected by bolts. The beam assembly mainly bears alternating loads and impact loads such as torque and bending during use. When the load is heavier and the road conditions are worse, the beam assembly is required to have better comprehensive mechanical properties such as rigidity, strength, and deformation resistance. Otherwise, the beam is easily deformed and cracked during use. The existing rigid beam structure has a small amount of deformation and is easily deformed and broken when subjected to torsional force, while the flexible beam structure has a good amount of deformation, but its rigidity is low and its strength is low, which cannot meet the load requirements. And the existing two kinds of beam structures are self-heavy, which cannot meet the requirements for the design of lightweight trucks.
