Abstract

The invention discloses an aluminum alloy passenger car stepping zone floor framework connecting structure. The aluminum alloy passenger car stepping zone floor framework connecting structure comprises a right side first transverse beam (1), a right side longitudinal beam (3), a right side enclosure vertical beam (16), a right side second transverse beam (2), a right side vertical beam (4), a left side first transverse beam (13), a left side longitudinal beam (12), a left side enclosure vertical beam (25), a left side second transverse beam (14), a left side vertical beam (15), a third middle transverse beam (9), a right side first inclined strut (5), a right side second inclined strut (8), a second middle transverse beam (7), a left side second inclined strut (10), a left side first inclined strut (11) and a floor first middle transverse beam (6). All beams are connected in a riveting way through pi-shaped joints (26), obtuse-angle joints (31), L-shaped joints (27) and T-shaped joints (28) respectively, so that an aluminum alloy framework is not deformed easily, the structural strength is high, and the overall structural rigidity of a stepping zone is enhanced.

Description

technical field [0001] The invention relates to a floor frame structure in the stepping area of ​​a passenger car, more specifically to an aluminum alloy passenger car stepping area floor frame connection structure, which belongs to the technical field of passenger car bodies. Background technique [0002] In recent years, with the increasing shortage of international energy resources, it is urgent to improve the fuel economy performance of automobiles, and the application of lightweight technology is an important way to improve fuel economy; at present, aluminum alloy bus body is an important way to reduce the weight of buses. [0003] The floor frame is an important part of the body frame, which plays the role of carrying passengers. For steel-structured cars, the floor frame in the stepping area is a steel frame. For details, see Figure 13 The floor frame of the stepping area includes the first steel beam 1 on the right side, the longitudinal beam 3 on the right side, the...
