The invention relates to the field of electric passenger cars, in particular to a front-section car frame for an electric passenger car, which comprises a first upright post, a second upright post, a third upright post, a fourth upright post, a first cross beam, a second cross beam, a third cross beam, a fourth cross beam, a first longitudinal beam, a second longitudinal beam, a third longitudinal beam and a fourth longitudinal beam, the second longitudinal beam, the third stand column, the third longitudinal beam and the fourth stand column are connected end to end to form a rectangular closed-loop frame, a steering gear support is installed in the closed-loop frame, a steering gear anti-collision beam is installed on the fourth stand column, and the steering gear anti-collision beam protrudes out of the face where the first stand column, the first cross beam and the fourth stand column are located. The steering gear box support is located in the closed-loop frame which is simple and reliable in structure, the steering gear box support can bear vertical bending and torsional loads in the steering process, and therefore the steering gear box is protected. The tow hook assembly can release the space of a front wall maintenance cabin of the electric bus, the steering machine anti-collision beam can protect a steering machine, the structure is simple, and safety and reliability are achieved.

    本发明涉及电动客车领域,具体是一种电动客车用前段车架,其包括组成立体框架的第一立柱、第二立柱、第三立柱、第四立柱、第一横梁、第二横梁、第三横梁、第四横梁、第一纵梁、第二纵梁、第三纵梁和第四纵梁,第二纵梁、第三立柱、第三纵梁和第四立柱首尾连接构成矩形的闭环框架,闭环框架内安装方向机支架,第四立柱上安装方向机防撞梁,方向机防撞梁凸出于第一立柱、第一横梁和第四立柱所在的面。本发明方向机支架位于结构简单可靠的闭环框架内,方向机支架能够承受转向时的垂向弯曲和扭转载荷,从而起到对方向机的防护作用。拖车钩总成能够释放电动客车前围检修舱的空间,方向机防撞梁能对方向机进行防护,结构简单,安全可靠。
