Embodiment Construction

[0023] Such as figure 1 As shown, the cross-sectional shape of the aluminum alloy profile 1 is a hollow rectangular ring 2, and the short sides of one side of the rectangle extend outwards from both ends to form wings 3, wherein the ratio of the short side to the long side of the rectangle is 1: 2. The wall thickness of the rectangular ring 2 and the thickness of the wings 3 are 3mm.

[0024] In other embodiments of the present invention, the ratio of the short side and the long side of the rectangle can also be 1:1, or 1:3, and the wall thickness of the rectangular ring and the thickness of the wings can also be 8 millimeters, or 5 mm.

[0025] Such as figure 2 As shown, the bus body 4 is a full load-bearing body surrounded by chassis trusses, surrounding frames and top arch frames. Among them, the left side frame and the right side frame in the surrounding frame are riveted with the chassis truss, and the front wall frame, the rear wall frame and the top arch frame in th...

Abstract

The invention provides a coach body structure. The coach body structure comprises a chassis, a four-periphery framework, and a top arch framework and is characterized in that: the coach body structure is formed by riveting aluminum alloy sections; the four-periphery framework consists of a grating framework consisting of vertical columns and transverse beams; and the section of each vertical column has a shape of a hollow rectangular ring, and the short side of the rectangular ring is extended outward from two ends respectively to form two wing parts. An aluminum alloy full-integral coach body is adopted, so that the weight of the whole coach is reduced, the number of passengers is increased, fuel oil consumption is reduced, and the emission of the whole vehicle is greatly reduced; an aluminum alloy structure ensures that the service life of the coach is prolonged; the coach has the aluminum alloy structure, so that electrophoresis and rust prevention is avoided during production of the coaches, the production cost is saved, and industrial emission is reduced; and a riveting mode is adopted by the whole lightweight coach body structure, so that complex and expensive welding equipment is not needed any more and production cost is saved.

Description

technical field [0001] The invention relates to automobile manufacturing and its materials, in particular to a lightweight passenger car body structure and its profiles using aluminum alloy profiles. Background technique [0002] The traditional vehicle structure generally includes the chassis and the body, the chassis and the body are relatively separated, the chassis must bear the weight of itself and the body, as well as the weight of the engine and other components installed on the chassis and the beam; the body only bears its own weight and cargo and passengers The weight does not bear the load of the chassis and frame. The center of gravity of this kind of body is relatively high, and the stability of high-speed driving is poor. When being hit, the chassis and the body will produce relative displacement, and the strength of the whole vehicle is weak. [0003] In order to solve the above problems, a full load-carrying body is proposed, and the whole vehicle is an integ...
