FIG. 1 is a schematic structural diagram of a multifunctional front beam assembly with a gas storage function according to the present invention;
FIG. 2 is a schematic view of a multifunctional front beam assembly with air storage function according to the present invention.
The labels in the figure are: 1-front beam assembly, 2-bumper bracket, 3-drain valve, 4-air inlet pipe, 5-air outlet pipe, 7-cab air bag suspension, 8-tow hook mounting hole, 9-front beam bracket, 10-tubular beam and 11-air storage cavity.
Detailed Description
The present invention will be further described with reference to the following examples, which are intended to illustrate only some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, other embodiments used by those skilled in the art without any creative effort belong to the protection scope of the present invention.
Example 1:
as shown in fig. 1, a multifunctional front beam assembly with a gas storage function comprises a front beam assembly 1; a front bumper stay 2; a drain valve 3; an air inlet pipe 4; an air inlet pipe 4; a cab airbag suspension 7; tow hook mounting holes 8.
The cab airbag suspensions 7 are arranged on two sides of the front beam assembly 1 and used for supporting a cab of the cab, the front beam assembly 1 comprises a tubular beam 10 and front beam supports 9 arranged on two sides of the tubular beam 10, and the tubular beam 10 and the front beam supports 9 are welded and fixed in a friction welding mode. The welding mode has high strength, strong torsion resistance and good sealing performance. The beam support adopts a forging structure, and has light weight and high strength.
The tubular beam 10 is preferably a circular tubular beam 10, and the circular tubular beam 10 and the front beam support 9 must be welded by friction welding, because in the present invention, the air storage cavity 11 is disposed throughout the circular tubular beam 10 in order to increase the space of the air storage cavity 11 inside the circular tubular beam 10, so that the circular tubular beam 10 must ensure the sealing property after being welded with the front beam supports 9 on both sides to perform the air storage function. Therefore, the conventional welding mode is not enough to meet the gas storage requirement of sealing performance, and only friction welding can be realized.
The air storage cavity 11 is arranged in the tubular beam 10, the air storage cavity 11 is communicated with an air inlet valve of an automobile through an air inlet pipe 4, and the air storage cavity 11 is communicated with cab airbag suspensions 7 on two sides one by one through an air outlet pipe 5. The air outlet pipe 5 and the air inlet pipe 4 are respectively connected to the tubular beam 10 through a quick connector and are communicated with the air storage cavity 11, and the bottom of the side wall of the tubular beam 10 is provided with a drain valve 3 communicated with the air storage cavity 11.
As shown in figure 2, the air storage function is added on the basis of the tubular beam 10, air is injected into the tubular beam 10 from a pressure reducing valve through an air inlet pipe 4, air supply requirements are provided for the cab airbag suspension 7 through an air outlet pipe 5, and air discharge and water discharge are realized through a water discharge valve 3.
After the national six-emission standard is implemented, the aftertreatment volume of the vehicle (such as a muffler) is increased, and a large amount of space is occupied compared with the national five-emission standard. Meanwhile, the demand of consumers on large oil tanks (endurance mileage) is increasing day by day, and the arrangement of the brake air cylinder increases the difficulty of the arrangement of the chassis of the whole vehicle. Therefore, the multifunctional front cross beam assembly 1 with the air storage function shares the function of a part of air storage cylinders, reduces the volume of the air outlet cylinder of the traditional vehicle type, and ensures that the volume of the whole vehicle is not increased but is more compact while the vehicle meets the national six emission standard, namely the volume of the post-treatment of the vehicle is increased. The arrangement space of the chassis of the six-model-in-country vehicle is increased, and the modular layout of the road vehicles can be realized.
The multifunctional front beam assembly 1 with the gas storage function mainly meets the gas demand of a cab airbag suspension 7, improves the space utilization rate of a chassis, can realize multifunctional integration, and can fix a bumper on a beam through a bumper bracket 2, and the fixation of a trailer hook can be met by designing a trailer hook mounting hole 8 as an internal thread.
The multifunctional integrated chassis has the advantages of light weight, high structural strength, capability of reducing the occupancy rate of the space arrangement of the chassis with the air storage function, realization of modular arrangement by multifunctional integration (a bumper, a trailer hook and an air storage cylinder), longer service life and high production and assembly efficiency.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
