Description

Technical Field

[0001] The utility model belongs to the technical field of commercial vehicle parts, and specifically relates to a suspension connection device for a urea tank of a commercial vehicle. Background Art

[0002] A commercial vehicle refers to a vehicle specifically designed for transporting passengers and goods in terms of design and technical features.

[0003] A urea tank, also known as a urea storage tank, is a device specifically used for storing urea solution, mainly applied in trucks and buses. The main function of the urea tank is to reduce the nitrogen oxide (NOx) pollution in the exhaust gas of diesel vehicles. After passing through the urea tank, the urea solution can react with NOx in the vehicle's exhaust gas treatment system to generate non-toxic and harmless nitrogen and water, thereby effectively reducing the emission of harmful gases in the exhaust gas and making it meet the national IV and above emission standards. The working principle of the urea tank is based on SCR (Selective Catalytic Reduction) technology, which is one of the main technologies for the diesel engine emission reduction system in the national IV and Euro IV emission standards implemented in 2008. In the SCR system, the urea solution is sprayed into the exhaust gas and undergoes a chemical reaction after mixing with the high-temperature exhaust gas to reduce NOx to nitrogen and water. In this process, the urea tank, as a storage device for the urea solution, plays a crucial role.

[0004] In the field of commercial vehicles, as an important part of the emission control system, the installation position and method of the urea tank are crucial for the space utilization and maintenance convenience of the whole vehicle. The common urea tank installation schemes on the market at present, such as the matching schemes of a vertical battery box with a side-mounted urea tank or a rear-mounted battery box with a side-mounted urea tank, all have certain limitations. The vertical battery box saves space, but it is difficult to repair the battery later; while the rear-mounted battery box increases the layout cost and complexity of the whole vehicle. Content of the Utility Model

[0005] In order to solve the problem that the urea tank and the battery box in the prior art occupy a large space, resulting in high complexity and cost of the whole vehicle space layout, the utility model provides a suspension connection device for a urea tank of a commercial vehicle.

[0006] The utility model is realized by the following technical solutions:

[0007] A suspension connection device for a urea tank of a commercial vehicle includes channel steel brackets. There are two channel steel brackets, and the cross-sections of both channel steel brackets are in a U-shape with the opening facing upwards; mounting panels are respectively connected to both ends of the channel steel brackets; a connecting cross beam is connected between the same-direction ends of the two channel steel brackets.

[0008] A further improvement of the utility model is that cutouts capable of accommodating the mounting panels are provided at both ends of the above-mentioned channel steel brackets.

[0009] A further improvement of the present invention is that the cross section of the installation panel is a U-shaped structure with the opening facing upward.

[0010] A further improvement of the present invention is that the installation panel is arranged to be inclined at 15°.

[0011] A further improvement of the utility model is that a sleeve nut is further provided on the above-mentioned installation panel, and the sleeve nut passes through the installation panel and can provide a mounting interface for the urea tank.

[0012] A further improvement of the utility model is that the flange surface of the sleeve nut is connected to the mounting panel by spot welding.

[0013] A further improvement of the utility model is that bolt mounting holes are provided on the flanges at both ends of the channel steel bracket.

[0014] A further improvement of the utility model is that both ends of the connecting beam are provided with limiting mounting holes corresponding to the bolt mounting holes.

[0015] A further improvement of the utility model is that a large circular hole for installation technology is provided in the middle of the connecting crossbeam.

[0016] A further improvement of the utility model is that the cross section of the connecting beam is a 冂-shaped structure with the opening facing downward.

[0017] It can be seen from the above technical solutions that the beneficial effects of the utility model are: 1. It saves the installation space of the whole vehicle. Through the innovative suspension connection method, the installation of the urea tank is more compact and does not take up too much space. 2. It improves the convenience of battery maintenance. Since the urea tank and the battery box adopt a separate design, and the urea tank suspension connection device has a simple structure, it is easy to disassemble and install, which facilitates the later maintenance of the battery. 3. It relatively reduces the layout cost of the whole vehicle. Compared with the rear battery box solution, this case does not require large-scale changes to the whole vehicle, reducing the layout cost and complexity. BRIEF DESCRIPTION OF THE DRAWINGS
