Description

Technical Field

[0001] The utility model relates to the technical field of commercial vehicle installation, in particular to an air storage cylinder installation structure. Background Art

[0002] At present, there are two positions for installing the gas cylinder. The first is to install it on the outer surface of the frame through a bracket. This installation method is generally used for installing gas cylinders with more space on the outer side of the frame; the other is to install it on the inner surface of the frame through a bracket. This installation method is because there is no space on the outer side of the frame and it is installed on the inner side of the frame. For this installation method, there are the following problems: since the gas cylinder is set on the inner side of the frame, the gas cylinder has a certain floating property when installed, and due to the different arc heights of the frame, the installation position relative to the lower side of the frame will also change accordingly. The gap between it and the transmission shaft is not easy to control, and it is easy to interfere with the transmission shaft. Moreover, since the gas cylinder is connected to the bracket through a band, after long-term use, the band is subjected to long-term stress on the side of the band due to the gravity of the gas cylinder, and due to the constant vibration of the vehicle during driving, the band is easy to break, and then fall on the transmission shaft, causing a traffic accident. At the same time, through the band connection, the band is relatively floating at the gas cylinder position, and the installation position of the gas cylinder floats greatly before and after, and it is also easy to interfere with the transmission shaft, and the vehicle assembly consistency is poor. Utility Model Content

[0003] The utility model aims to provide an air cylinder installation structure, which is used to solve the problems that the air cylinder is installed by connecting a band with a bracket in the prior art, resulting in large position fluctuation of the air cylinder and poor vehicle assembly performance.

[0004] The utility model solves the above problems through the following technical solutions:

[0005] A gas cylinder installation structure includes a plurality of gas cylinder pocket beams arranged on the inner sides of lower wing portions of a left longitudinal beam and a right longitudinal beam of a vehicle frame, the gas cylinders are arranged on the upper portions of the plurality of gas cylinder pocket beams, the gas cylinders are installed and fixed by the plurality of gas cylinder pocket beams, and the plurality of gas cylinder pocket beams are formed with raised portions for avoiding a transmission shaft, groove portions for installing the gas cylinders, and horizontal portions connected to the left longitudinal beam and the right longitudinal beam of the vehicle frame.

[0006] As a further improvement of the utility model, the air reservoir pocket beam is made of spring steel so that the air reservoir pocket beam has elasticity.

[0007] As a further improvement of the present invention, the groove portion is formed with no less than one positioning hole, and the air storage cylinder is installed through the positioning hole.

[0008] As a further improvement of the utility model, the horizontal portion is formed with no less than one mounting hole, through which the air reservoir pocket beam is mounted on the inner sides of the lower wing portions of the left longitudinal beam and the right longitudinal beam of the frame.

[0009] As a further improvement of the utility model, a mounting pad matched with the positioning hole of the air reservoir pocket beam is arranged outside the air reservoir, and the screw is connected to the mounting pad of the air reservoir through the air reservoir pocket beam.

[0010] As a further improvement of the present invention, the screw is a self-tapping screw.

[0011] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0012] The air cylinder mounting structure is mounted on the lower wing surface of the frame via an air cylinder pocket beam, so that the relative positions of the air cylinder and the transmission shaft are fixed. The air cylinder is directly mounted on the air cylinder pocket beam and is no longer fixed via a hoop, so it is not affected by the height of the frame and also prevents interference with the transmission shaft due to mounting errors during installation. The number of parts is reduced, the assembly efficiency is high, and the front and rear positions of the air cylinder are fixed during installation, so the vehicle assembly has high consistency, is stable and reliable for long-term use, has high safety, and has a high degree of commonality.
