The rigid frame comprises a front bumper, a front end beam, a ring beam, a lifting beam, a right longitudinal beam, a left longitudinal beam and a rear bumper assembly which are sequentially welded, and the front bumper is located at the foremost end of the frame; the right longitudinal beam and the left longitudinal beam are symmetrically arranged in parallel and are welded by high-strength plates to form box-shaped sections; the rear bumper assembly is positioned at the tail part of the frame to form a frame main body, and each sub-assembly is independently tailor-welded and processed. The bearing capacity is greatly improved, the stress concentration part is structurally reinforced, the cracking risk is reduced, the reliability is improved, the production difficulty is reduced, the manufacturing efficiency is improved, and the method is suitable for wide application and popularization.
本发明公开了非公路自卸车刚性车架,包括依次焊接的前保险杠、前端梁、圈梁、举升梁、右纵梁、左纵梁、后保险杠总成,前保险杠位于车架最前端;右纵梁、左纵梁呈平行对称布置,均由高强度板焊接形成箱型截面;后保险杠总成位于车架尾部,构成车架主体,各分总成独立拼焊加工。本发明承载能力大幅提高,在应力集中部位进行结构加强,降低开裂风险,提高可靠性,降低生产难度,提升制造效率,适合广泛推广应用。
