Description

cab front wall

technical field

The utility model relates to the technical field of automobile cabs, in particular to a front wall of a cab.

Background technique

The front part of the body is an important part of the body, and its exterior parts are the embodiment of the image characteristics of the vehicle. The functional parts on the front wall of the mask are dense, so that the front wall plays an important role in the design of the entire cab body.

The front wall structure should take into account the following many functional requirements: because there are many functional parts installed on the front wall, there are many holes on the front wall, so the front wall is required to have good rigidity, and many cabs are installed on the front suspension. On the front wall, the front wall structure is required to have good strength; and the front collision and pendulum collision of the vehicle safety require the front wall to have a certain energy-absorbing performance in order to ensure the living space of personnel.

There are two main types of cab front wall:

l. Plate structure: This structure is stamped and formed by two thicker sheets inside and outside, and then welded together. Although the front wall strength and rigidity of the plate structure are better, the weight is relatively heavy, and because two large sheets are used The ribs are stamped out, and a "beam cavity" is formed after welding, so forming is difficult, and the tonnage requirements for stamping processing and equipment are relatively high. At present, domestic machining capabilities are difficult to keep up with, so it is rarely used on domestic car bodies, but only used on European cars such as Renault and Mercedes-Benz.

2. Beam structure: This structure is welded by the front wall beam and the front wall, which is lighter than the front wall of the plate structure. The traditional beam-type front wall structure is generally welded by the upper and lower beams and the front wall baffle. However, due to the many maintenance function parts installed on the front wall, there are many holes on the front wall. The front wall is subjected to a large bending moment and fatigue damage, resulting in frequent cracking of the front wall panel and the front wall lower beam. This structure is often used in Japanese cars.

Contents of the invention

It can be seen that the prior art has the defects of heavy weight, difficult molding and frequent cracking of the dash panel.

Therefore, in order to overcome the deficiencies in the prior art, the utility model provides a cab cowl for the technical problem to be solved, which can not only make the structure lightweight, but also ensure the structural strength and rigidity, and is easy to process and manufacture.

In order to solve the above-mentioned technical problems, the cab cowl of the utility model includes a cowl baffle provided with a plurality of installation holes, and the upper and lower ends of the cowl baffle are respectively installed with a cowl upper beam and a cowl lower beam. The left and right sides of the cowl baffle are respectively equipped with a left vertical plate and a right vertical plate, and the two ends of the cowl lower beam are respectively welded with a left longitudinal beam and a right longitudinal beam, and the left longitudinal beam and the right longitudinal beam The upper end of each is connected with the lower end of the upper cross beam of the front wall so that the front wall beam forms a frame structure, and the inner sides of the left longitudinal beam and the right longitudinal beam are all provided with force transmission brackets.

As a further improvement of the above cab cowl of the utility model, a reinforcement plate is provided on the cowl baffle at the edge of the installation hole.

The beneficial effects of the utility model are as follows: the mounting holes on the cowl baffle are provided with reinforcing plates for each functional part, which ensures the installation strength of the functional parts installed on the cowl baffle, and the arrangement of the entire reinforcing plate makes the front The force of the wall baffle is very uniform, eliminating high stress points and preventing the breakage of the front wall baffle; the front wall upper beam, the left longitudinal beam, the right longitudinal beam and the front wall lower beam form a frame structure, which transmits the suspension The force is transmitted to the entire cab, which effectively reduces the stress of the suspension installation part and reduces the cracking of the front wall beam; the force transmission bracket installed on the inside of the left longitudinal beam and the right longitudinal beam reduces the number of steering columns and instruments installed on the front wall. The system collapses to the driver to ensure the living space of the driver and passengers; the weight of the entire front wall structure is relatively light, which is equivalent to the weight of the traditional beam structure.

After reading the detailed description of the embodiments of the utility model in conjunction with the accompanying drawings, other features and advantages of the utility model will become clearer.

Description of drawings

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail, wherein:

Fig. 1 is the structural representation of the utility model.

Detailed ways

Below in conjunction with accompanying drawing and the specific embodiment of the present utility model, the utility model driver's cab front wall is described as follows.

Embodiment: The utility model comprises a cowl baffle 1 provided with a plurality of installation holes 10, the upper and lower ends of the cowl baffle 1 are respectively installed with a cowl upper beam 2 and a cowl lower beam 3, and the cowl baffle 1 The left and right sides are respectively equipped with a left vertical board 4 and a right vertical board 5. The shape can be L-shaped, and the upper ends of the left longitudinal beam 6 and the right longitudinal beam 7 are connected with the lower end of the dash panel 1 . The front wall upper beam 2, the front wall lower beam 3, the left side beam 6 and the right side beam 7 are welded into a frame structure; the frame structure plays the role of force transmission; it is universal and safe; the front wall baffle 1 1. The left vertical plate 4 and the right vertical plate 5 are welded into a whole, and then the above-mentioned welded frame structure is installed and welded.

A reinforcement plate 9 is provided on the dash panel 1 at the edge of the installation hole 10, which ensures the installation strength of the maintenance function parts installed on the dash panel, and the arrangement of the entire reinforcement panel makes the stress of the dash panel evenly distributed and concentrated stress, greatly reducing the risk of dash panel cracking. The inner sides of the left longitudinal beam 6 and the right longitudinal beam 7 are equipped with a force transmission bracket 8, which transmits the force of the front pendulum and the front collision to the floor longitudinal beam, effectively reducing the impact of the steering column and instrument system installed on the front wall on the driver. The collapse ensures the living space of the driver and passengers, and improves the safety performance of the car.

The above-mentioned embodiment is a preferred implementation mode of the present utility model, but the implementation mode of the present utility model is not limited by the above-mentioned embodiment, and any other changes, modifications and substitutions made without departing from the spirit and principle of the present utility model , combination, and simplification, all should be equivalent replacement methods, and are all included in the protection scope of the present utility model.
