bus skeleton assembly

Abstract

The invention provides a bus skeleton assembly which comprises a front wall, a left wall, a right wall and a rear wall, wherein the front wall comprises a front left vertical column and a front right vertical column; the left wall comprises a left upper beam and a left waist beam; the right wall comprises a right upper beam and a right waist beam; the rear wall comprises a rear left vertical column and a rear right vertical column; the front ends of the left upper beam and the left waist beam are connected with the front left vertical column; the rear ends of the left upper beam and the left waist beam are connected with the rear left vertical column; the front ends of the right upper beam and the right waist beam are connected with the front right vertical column; the rear ends of the right upper beam and the right waist beam are connected with the rear right vertical column. One vertical column is shared by the left wall, the right wall and the front wall and one vertical column is shared by the left wall, the right wall and the rear wall, so that the weight of the bus skeleton is reduced and the bus skeleton can be conveniently mounted.

Description

technical field [0001] The invention relates to the technical field of bus frame, in particular to a bus frame assembly. Background technique [0002] Whether it is a full load or a half load chassis, traditional large and medium-sized buses generally adopt a steel body structure, and the curb weight is very heavy. The weight of the body consumes about 70% of the energy. Research data shows that for every 10% reduction in vehicle weight, fuel efficiency can be increased by 7% to 8%; for every 100 kg reduction in vehicle curb weight, fuel consumption per 100 kilometers can be reduced by 0.3 to 0.6 liters; The problem is how to make the car lighter. Moreover, after the car is lightweight, its acceleration performance, braking distance and other handling performance will be greatly improved. This means that the light weight of the car alone can not only achieve the purpose of energy saving and emission reduction, but also improve the overall performance of the car. Today, w...

[0006] In addition, the above invention patent also discloses a riveting structure, which includes a fixing plate and two limiting plates A and B that are vertically fixed on the fixing plate and arranged parallel to each other. A groove for profile B to be embedded is formed between the limiting plates B; or, the riveting structure includes a riveting plate, rivet group A and rivet group B, and the riveting plate includes a fixing plate and two vertically fixed The limiting plate A and the limiting plate B arranged on the fixed plate and mutually arranged, the limiting plate A and the limiting plate B form a limiting plate group that can be embedded in the profile B, as described in the description attached to the above-mentioned invention patent Figure 12 with instructions attached Figure 13 As shown, although the riveted structure can enhance the stability of the connection between the riveted plate and one of the two perpendicular aluminum profiles, the shear force of the riveted structure still mainly acts on the rivet, making the rivet a bus The main load-bearing parts of the car frame, the overall load-bearing capacity of the bus frame is weak, and the service life is short
