The invention discloses an off-highway mining dump truck frame front end beam, a frame and an off-highway mining dump truck, the front end beam comprises a front plate, an upper plate, a lower plate, an inner web plate and an outer web plate, and the upper plate, the lower plate, the inner web plate and the outer web plate are all bent plates; the upper plate, the lower plate, the inner web and the outer web are oppositely arranged in parallel, the front plate is arranged at the front end of the front end beam and fixedly connected with the upper plate, the lower plate, the inner web and the outer web, and therefore the front end beam forms a box structure; the rear end of the front end beam is open so that the rear end of the front end beam can be spliced with the front end of a longitudinal beam of a frame in an inserted mode. Compared with other simple connection modes, the design that the rear end opening of the frame front end beam and the front end of the frame longitudinal beam are spliced in an inserted mode can provide larger contact area and connection strength; the whole frame front end beam is respectively bent towards the outer side of the frame, so that the bending rigidity of the frame is improved; and the internal space of the frame is enlarged, and different power systems and cooling systems can be adapted.
本发明公开了一种非公路矿用自卸车车架前端梁、车架及非公路矿用自卸车,所述前端梁包括前板、上板、下板、内腹板、外腹板,所述上板、下板、内腹板、外腹板均为折弯板;所述内腹板和所述外腹板相对平行设置,所述前板设置于所述前端梁的前端,分别与所述上板、所述下板、所述内腹板和所述外腹板固定连接,从而使所述前端梁形成箱盒结构;所述前端梁的后端敞口以使所述前端梁的后端与车架纵梁前端对插拼接。本发明车架前端梁后端敞口与车架纵梁前端对插拼接的设计,相比其他简单的连接方式,能提供更大的接触面积和连接强度;车架前端梁整体分别向车架外侧折弯,提高了车架弯曲刚度;扩大了车架内部空间,可适配不同动力系统及冷却系统。
