Abstract
The utility model relates to an aluminum alloy front collision beam of an automobile, which is formed by optimizing components on the basis of commercial aluminum alloy, homogenizing an aluminum ingot, carrying out extrusion molding and bending by utilizing a pressure bending method. The cross section of the aluminum alloy front collision beam is in a shape like a Chinese character mu, and the integral aluminum alloy front collision beam is in bilateral symmetry and is in an arc shape, thereby the installation of front attachments is ensured without generating interference with the peripheral parts. In the utility model, the characteristics of light weight, high strength, good impact resistance and mature extrusion bending process of the aluminum alloy material are sufficiently utilized, an original steel front collision beam is optimized and integrated into an integral section bar member, therefore, the weight reducing effect is obvious, and the safety performance and the energy saving effect are improved to a certain extent.
Description
Technical field
The utility model collides crossbeam before relating to a kind of aluminium alloy car.
Background technology
Crashproof crossbeam is as the buffer body that absorbs crash energy before the automobile, and its crash-worthiness plays crucial effects in automotive safety when low speed collision.The crashproof crossbeam of aluminum alloy is compared with the crashproof crossbeam of steel can not only reach the weight-saving purpose, more can improve the energy absorbing in the collision process.
At present, common preceding collision crossbeam mainly is to adopt steel structure, as shown in Figure 1, mainly by the first crossbeam outside plate 11,12 two steel parts of the first crossbeam inner panel are welded, and collide box at the two ends of outside plate by welding then, are connected with left and right sides front side member respectively by bolt at last.These steel components collide the crossbeam assembly before forming by welding, general assembly again after punching press, its welding deformation is not easy control, poor dimensional stability, it is many to relate to operation, and technological process is long, production efficiency is low, and these parts all are steel parts, is unfavorable for realizing lightweight.
The utility model content
The purpose of this utility model is the above-mentioned many deficiencies at the prior art existence, proposes to collide crossbeam before a kind of aluminium alloy car.
The technical solution of the utility model is as follows:
Collision crossbeam before a kind of aluminium alloy automobile, the integrative-structure that described preceding collision crossbeam is aluminium section bar extruding and brake forming, cross-beam body left-right symmetric and curved is provided with bolt mounting holes and towing hook via hole at the cross-beam body two ends.Collision crossbeam adopts aluminium section bar extruding and brake forming before this, adopts a profiled member to replace two steel sheet metal components, both can avoid the welding deformation of crossbeam, size instability, the weight of collision crossbeam before can also alleviating simultaneously.And guarantee the installation of front attachment and do not interfere with parts on every side by symmetrical arcuate structure.
In order further to alleviate crossbeam weight, and guarantee the intensity of crossbeam the cross sectional shape of described cross-beam body to be designed to " order " font, from cross-beam body from the cross section, it is to form rectangle frame, and have the structure of reinforced rib in the rectangle frame with entablatrance, cross sill, left longeron, right vertical beam

Fig. 2 is a collision beam structure scheme drawing before the utility model aluminum alloy;
Fig. 3 is a collision crossbeam cross sectional view before the utility model aluminum alloy;
Among Fig. 1, the 11-first crossbeam outside plate, the 12-first crossbeam inner panel;
Among Fig. 2,21-mounting hole, 22-towing hook via hole, 23-cross-beam body;
Among Fig. 3,31-cross sill, 32-left side longeron, 33-entablatrance, 34-right vertical beam, the right reinforced rib of 35-, 36-left side reinforced rib.
The specific embodiment
Further specify the structure of colliding crossbeam before this below in conjunction with accompanying drawing:
As shown in Figure 2, collision crossbeam adopts aluminium alloy extrusions before this, be shaped by extruding and bending process, collision cross-beam body 23 is integrative-structures of aluminium section bar extruding and brake forming before the aluminum alloy, collision cross-beam body 23 left-right symmetric and curved before the aluminum alloy, the collision crossbeam is approaching before its radian and the former steel, does not interfere with parts around front bumper and the radiator etc. with assurance.The two ends, the left and right sides of collision cross-beam body 23 are respectively equipped with mounting hole 21 and towing hook via hole 22 before aluminum alloy, and collision cross-beam body two ends are connected with the collision box at mounting hole 21 places by bolt before the aluminum alloy, and towing hook via hole 22 is to guarantee the installation of towing hook.
The section form of collision crossbeam is symmetrical " order " font before the aluminum alloy, is the rectangle frame that is formed by cross sill 31, left longeron 32, entablatrance 33, right vertical beam 34, and right reinforced rib 35 and left reinforced rib 36 are arranged in rectangle frame, as shown in Figure 3.Cross sill is 4mm, and left and right strengthening ribs is 2mm, and all the other wall thickness are 3mm.
Claims (2)
1. collide crossbeam before an aluminium alloy automobile, it is characterized in that: the collision crossbeam is the integrative-structure of aluminium section bar extruding and brake forming before described, and cross-beam body left-right symmetric and curved is provided with bolt mounting holes and towing hook via hole at the cross-beam body two ends.
2. collision crossbeam before the aluminium alloy automobile according to claim 1, it is characterized in that: described cross-beam body is from the cross section, it is to form rectangle frame with entablatrance, cross sill, left longeron, right vertical beam, and in rectangle frame, having the structure of reinforced rib, the cross sectional shape of cross-beam body is " order " font.
