Problems solved by technology

[0002] Traditional 7-meter buses are remanufactured from light truck chassis. The frame is mostly a groove-shaped straight girder structure, and the profiled cross-section remains the same before and after. The upper plane of the frame is controlled to reach more than 800mm according to the height of the ground, and only three or even four steps can be realized, which cannot meet the needs of passengers getting on and off quickly

Abstract

The invention relates to a design method of a 7-meter front-arranged passenger car chassis frame. The chassis frame comprises a support, transverse beams and longitudinal beams and is characterized in that the longitudinal beams comprise a left front-section longitudinal beam, a right front-section longitudinal beam, a left middle-section longitudinal beam, a right middle-section longitudinal beam, a left back-section longitudinal beam and a right back-section longitudinal beam, the transverse beams are composed of a first transverse beam, a second transverse beam, a third transverse beam, a fourth transverse beam, a fifth transverse beam, and a sixth transverse beam, one ends of two front-section longitudinal beams are in butt joint with one ends of two middle-section longitudinal beams through connecting plates at two ends of the third transverse beam, the other ends of the two middle-section longitudinal beams are in butt joint with two back-section longitudinal beams, the first transverse beam and the second transverse beam are welded between the two front-section longitudinal beams, the fourth transverse beam and the fifth transverse beam are welded between the two middle-section longitudinal beams, the sixth transverse beam is welded between the two back-section longitudinal beams, the cross section of each front-section longitudinal beam is in a Z structure, the cross section of each middle-section longitudinal beam and the cross section of each back-section longitudinal beam are respectively in a groove-shaped structure, and the back-section longitudinal beams are provided with arc-shaped protrusion in the central line of a rear axle.

Description

technical field [0001] The invention relates to a bus chassis, in particular to a design method for a chassis frame of a 7-meter front bus, which belongs to the field of automobiles. Background technique [0002] Traditional 7-meter buses are remanufactured from light truck chassis. The frame is mostly a groove-shaped straight girder structure, and the profiled cross-section remains the same before and after. The upper plane of the frame is controlled to reach more than 800mm according to the height of the ground, and only three or even four steps can be realized, which cannot meet the needs of passengers getting on and off quickly. In order to meet the needs of the public transport market for a 7-meter front-mounted two-step bus, a special frame must be designed to meet the requirements of the two-step bus chassis. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a design method for the chassis frame of a 7-mete...
