Description

car beam

technical field

The utility model relates to a connecting piece used for connecting the front and rear cabin bottom plates and longitudinal beams of a driver's cab, in particular to an automobile beam. the

Background technique

Since the reform and development, especially in recent years, my country's automobile industry has developed strongly. China has become the third country after the United States and Japan to produce more than 10 million vehicles per year, and has entered the ranks of countries with tens of millions of vehicles. In order to meet the rapid development requirements of the automobile industry, for the auto parts supporting manufacturers that play a decisive role in the production speed and quality of automobiles, the requirements for the structure, quality and quantity of the parts produced are getting higher and higher. the

We know that the automobile beam is mainly used to connect the front and rear compartments of the cab and the longitudinal beam of the whole vehicle. In addition, the left and right sides of the cab are safely connected into one body through welding with the middle longitudinal beam. the

Due to its unreasonable structure, the existing automobile beams have some shortcomings and deficiencies, which are manifested in ① due to the simple structure, insufficient rigidity and strength, and poor safety and reliability; It is realized by three-part welding, that is, bridged by other parts to realize the transition, the process tooling is complicated, it is not easy to install, and the production efficiency is low. the

Contents of the invention

The purpose of the utility model is to provide an automobile beam with simple and reasonable structure, high strength, safety, reliability, easy assembly, simple process, low investment in tooling equipment, high production efficiency and stable product quality. the

The purpose of this utility model is achieved in that the crossbeam is a trough structure in the shape of "凵" in section, including a straight trough section, an arc transition section connecting the straight trough section, and a curved trough section connecting the arc transition section, The two side edges of the straight groove section are processed with a first connecting flange surface overlapping with the front and rear cockpit, and the two side edges of the arc-shaped transition section are processed with a second connecting flange surface overlapping with the bottom plate. The edge of both sides of the curved groove section is processed with a third connecting flange surface overlapping with the longitudinal beam. The side surface of the curved groove section close to the arc-shaped transition section is processed with raised reinforcing ribs, and the bottom of the curved groove section is processed There is a connecting hole, a wiring harness through hole is opened on the side wall of the straight slot section, and the end of the curved slot section is a lap end connected with the bottom of the floor. the

The technology of the utility model has the following advantages and positive effects:

1. The crossbeam of the utility model is deeply formed, and the raised ribs are designed around it, which increases the strength and rigidity of the workpiece, and the arc transition method between the front and rear sections solves the problem of large drop.

2. The utility model is formed by a common stamping machine and a special mold. The process is simple, the variables are stable, and the efficiency is high, which can meet the needs of mass production. the

3. The utility model has simple and reasonable structure, good welding strength, safety and reliability, convenient assembly, simple process, low investment in tooling equipment, high production efficiency and stable product quality. the

Description of drawings

Fig. 2 is a side projection view in Fig. 1 of the utility model. the

Detailed ways

As shown in attached drawings 1 and 2: the crossbeam is a groove-shaped structure with a cross-section in the shape of an "凵" shape formed by one-time punching of a special mold through an ordinary punching machine, including a straight groove section 1 and an arc-shaped transition section connecting the straight groove section 1 2. The curved groove section 3 connecting the arc-shaped transition section 2, the straight groove section 1 and the curved groove section 3 are connected by an arc-shaped transition section 2 to increase the strength and rigidity of the body, and the straight groove section The edges on both sides of section 1 are processed with the first connecting flange surface 4 overlapping with the front and rear cockpit, and the edges on both sides of the arc-shaped transition section 2 are processed with the second connecting flange surface 5 overlapping with the bottom plate. The edge of both sides of the groove section 3 is processed with a third connecting flange surface 6 overlapping with the longitudinal beam, and the side surface of the curved groove section 3 close to the arc transition section 2 is processed with raised ribs 7, and the curved groove section The bottom of the section 3 is processed with a connecting hole 8, and the side wall of the straight trough section 1 is provided with a wiring harness via hole 9, and the end of the curved trough section 3 is a lap end 10 connected to the bottom of the floor. the
