The invention relates to an automobile front end beam system force transmission structure which is characterized in that a front collision beam and front auxiliary frame beam double-layer energy absorption structure is formed by a Z-direction space at the front end of an automobile to absorb energy at the initial stage of collision, three inverted-L-shaped force transmission structures are formed by the Z-direction space and the Y-direction space of the automobile, and a cabin edge beam front end plate serves as the initial position; a cavity structure formed by a longitudinal beam front end connecting piece and a side beam connecting piece in the Y direction transmits collision force to the rear of a vehicle through a path I and a path II, a force transmission path is formed by a front auxiliary frame mounting plate and a front auxiliary frame longitudinal beam in the Z direction, component force of the path II is transmitted to a path III, the bearing force of the path II is effectively decomposed, and the collision force is effectively reduced. A Y-direction and Z-direction dual energy absorption and force transmission inverted-L-shaped structure is formed by reinforcing cross beams and connecting pieces such as a front collision cross beam, a front auxiliary frame cross beam, an engine compartment edge beam front section, an engine compartment edge beam rear section, a fender mounting plate and a fender mounting plate front section. The collision force is effectively prevented from being directly transmitted to the passenger compartment to injure passengers, and the safety of the passengers is effectively protected.
本发明涉及一种汽车前端梁系传力结构,利用车辆前端Z向空间形成前碰撞横梁和前副车架横梁双层吸能结构吸收碰撞初期能量,利用车辆Z向空间、Y向空间形成倒“L”型的三条传力结构,以舱边梁前端板为初始位置,Y向由纵梁前端连接件和边梁连接件形成的腔体结构将碰撞力通过路径Ⅰ和Ⅱ向车后传递,Z向由前副车架安装板和前副车架纵梁形成传力路径,将路径Ⅱ的分力向路径Ⅲ传递,有效分解路径Ⅱ承载力,通过前碰撞横梁、前副车架横梁、发动机舱边梁前段、发动机舱边梁后段、翼子板安装板及翼子板安装板前段等加强横梁及连接件形成的Y向、Z向双重吸能、传力的倒“L”型结构。有效避免碰撞力直接传递到乘员舱,导致乘员受伤,有效保护乘员安全。
