[0057] A vehicle comprises the suspension air tank assembly; the suspension air tank assembly is connected to the suspension air spring air supply system of the whole vehicle, so as to facilitate air supply or air collection operation for the air spring air supply system.

[0058] specific:

[0059] The present invention discloses a suspension gas storage tank assembly. The suspension gas storage tank assembly disclosed by the present invention mainly facilitates the connection with the vehicle body 6 .

[0060] In the present invention, on the basis of meeting product performance and durability, a soft cushion is added to the mounting position of the vehicle body 6 to improve the NVH performance of the whole vehicle; a pressure relief valve assembly is added at one end of the gas storage tank 1 to improve safety performance; the welding process for connecting the cylinder 11 and the end cover is adjusted to friction welding to reduce welding defects and improve airtightness; and a hanging positioning pin is added to improve the convenience of assembly.

[0061] The present invention discloses a suspension gas tank assembly scheme, which improves the NVH performance, safety, air tightness, assemblability and other requirements of the gas tank 1. The present invention can realize that the suspension gas tank assembly has multiple points of connection with the vehicle body 6, and ensure the stability of the suspension gas tank assembly installed on the whole vehicle.

[0062] In addition, in the present invention, the suspension gas tank assembly includes a gas tank 1, a hanging bracket 3 is provided at one end of the gas tank 1, and a supporting bracket 2 is provided at the other end, and a fastening component 101 is provided on the hanging bracket 3 and the supporting bracket 2; the gas tank 1 has multiple mounting points with the vehicle body 6. In the present invention, two fastening components 101 are provided on the hanging bracket 3, and one fastening component 101 is provided on the supporting bracket 2, so that the suspension gas tank assembly has at least three mounting points with the vehicle body 6. Of course, the number of mounting points can also be set to other numbers as needed.

[0063] At the same time, each fastening component 101 of the present invention is provided with a mounting pad 5, and pad connections are added at three mounting points to achieve a vibration isolation effect and improve NVH performance.

[0064] A pressure relief valve mechanism is added to the left end cover 12, and a safety threshold is set in accordance with the air spring control strategy, which reduces the rupture problem caused by the increase in air pressure inside the gas tank 1 and improves safety. In the traditional design, the connection method between the cylinder 11 of the gas tank 1 and the end cover is gas shielded welding. This connection method has defects such as air holes and weld penetration, which causes the air tightness of the gas tank assembly to decrease. The new solution is adjusted to friction welding connection. This solution has fewer welding defects and improves air tightness.

[0065] In the absence of additional auxiliary tooling equipment, a mounting locating pin is added to the side mounting position of the mounting bracket 3 to improve the assembly of the gas storage tank 1 and the vehicle body 6.

[0066] At the same time, in the present invention, both the hanging bracket 3 and the supporting bracket 2 are provided with a fastening component 101; a mounting pad 5 is provided in the fastening hole, that is, a pad structure is added to the mounting position of the vehicle body 6, so that the vibration generated during the air intake and exhaust process inside the gas tank can be isolated through the pad, thereby improving the NVH performance of the whole vehicle.

[0067] The connection method between the cylinder 11 and the end cover is adjusted to friction welding to reduce welding defects and improve air tightness; a hanging positioning pin is added, and during the assembly of the gas tank assembly, the gas tank assembly is moved horizontally so that the lateral pre-hanging positioning pin 4 is inserted into the reserved hanging hole of the vehicle body 6. After all the positioning pins are inserted, the bracket mounting hole bolts are tightened to improve assembly.

[0068] The pressure relief valve of the gas tank 1 provides a safety threshold for the gas tank assembly and is connected to the left end cover 12 by gas shielded welding; the hanging bracket 3 connects the gas tank 1 body and the left end of the vehicle body 6, and is connected to the left end cover 12 by gas shielded welding, and provides a mounting hole or mounting position for the hanging positioning pin. When the mounting hole is set, the hanging positioning pin 4 is connected to the hanging bracket 3 by interference fit; the cylinder 11, as the main part of the gas tank assembly, is friction-welded with the left end cover 12 and the right end cover 13 to form the main body of the gas tank 1, which assumes the main function of storing gas; the supporting bracket 2 connects the gas tank 1 body and the right end of the vehicle body 6, and is connected to the right end cover 13 by gas shielded welding, and provides an installation space for the base and quick-connect plug by gas shielded welding; the mounting cushion 5 is assembled and connected to the hanging bracket 3 and the supporting bracket 2 respectively, and provides a mounting hole for the fastener to connect the vehicle body 6.

[0069] The hanging bracket 3 and the supporting bracket 2 are both made of aluminum alloy, and have reinforcing rib structures such as flanges and bosses to improve the bracket connection stiffness and fatigue durability and improve the structural mode; based on the connection relationship of the above sub-components, a gas tank assembly is formed.

[0070] The principle of the gas tank assembly scheme involved in the present invention is as follows: a pressure relief valve structure is added to the left end cover 12 side of the gas tank 1, and the pressure relief valve is installed and connected to the cylinder 11 by welding. The maximum working pressure of the gas inside the gas tank 1 is 18 bar. In order to ensure the safety performance of the air spring circuit, the safety threshold of the pressure relief valve is set to 20 bar.

[0071] When the internal pressure of the gas storage tank 1 rises to more than 20 bar due to external factors, the pressure relief valve switch opens to release the pressure, and after the pressure drops to 20 bar, the pressure relief valve closes, thereby ensuring that the internal pressure of the gas storage tank 1 does not exceed 20 bar.

[0072] The mounting cushion 5 is composed of a metal frame and a rubber cushion, and is connected with the mounting hole of the hanging bracket 3 through an assembly relationship. The height of the metal frame is 7.8 mm, the thickness of the rubber cushion is 8 mm, the compression amount is 0.2 mm, and the thickness of the supporting bracket 2 is 2.5 mm; the thickness of the cylinder 11 and the end cover are both 2.5 mm, and they are connected by friction welding. After welding, the internal fusion depth of the connection between the cylinder 11 and the end cover is the same as the thickness of the metal plate.

[0073] The gas tank assembly is at the same height as the installation position. With the pre-mounting hole of the vehicle body 6 as a reference, the gas tank assembly is moved horizontally so that the positioning pin 4 on the mounting bracket 3 is mounted and inserted into the process hole of the vehicle body 6. Then tighten the bolts of the support bracket 2 until the assembly torque is reached.

[0074] Make the mounting surface of the main and auxiliary positioning holes of the mounting bracket 3 fit with the matching surface of the vehicle body 6, and then screw in the bolts until the assembly torque is reached.

[0075] The size of the gas tank 1 support bracket 2 and the vehicle body 6 mounting bolt specification are M8.

[0076] The vehicle body 6 provides a 8mm*10mm mounting process hole; the mounting positioning pin 4 on the mounting bracket 3 has a length of 15mm and a diameter of φ6mm.

[0077] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
