As shown in fig. 1 to 6, the present embodiment provides an air spring upper bracket for an air suspension of a chassis of an automobile, which connects an air spring 100 having a concave structure 110 thereon and a frame 200, and which includes a bottom plate 1, a support plate 2 and a reinforcement plate 3, wherein the bottom plate 1 is connected with the air spring 100; the support plate 2 is arranged above the bottom plate 1 and comprises a main plate 21 and two wing plates 22 arranged on two sides of the main plate 21, the main plate 21 is connected with the frame 200, and the wing plates 22 and the main plate 21 are arranged at an included angle; reinforcing plate 3 is disposed between bottom plate 1 and air spring 100, and reinforcing plate 3 includes flat board 31 and two risers 32 that set up in flat board 31 both sides, and flat board 31 is connected with bottom wall butt of indent structure 110, and riser 32 is connected with bottom plate 1.

The reinforcing plate 3 is additionally arranged between the bottom plate 1 and the concave structure 110 of the air spring 100, so that a gap between the bottom plate 1 and the concave structure 110 is compensated, the strength of the upper bracket of the air spring is enhanced, the flat plate 31 of the reinforcing plate 3 is abutted against the bottom wall of the concave structure 110, and the stable connection between the upper bracket of the air spring and the air spring 100 is ensured; the wing plates 22 are additionally arranged on the two sides of the main plate 21 of the supporting plate 2, so that the connecting strength between the supporting plate 2 and the frame 200 is enhanced, and the plane where the wing plates 22 are located and the main plate 21 form an included angle, so that the stable connection between the air spring upper support and the frame 200 is ensured; in general, the air spring upper bracket can be suitable for connection between the air spring 100 with the concave structure 110 on the upper part and the frame 200, and has the advantages of high strength, reliable connection and the like.

In order to realize the connection between the support plate 2 and the frame 200, a first mounting hole 211 is provided on the main plate 21, a corresponding threaded hole is provided on the frame 200, and a mounting bolt 210 is inserted into the first mounting hole 211 and is in threaded connection with the threaded hole of the frame 200. The threaded connection is convenient and firm, the mounting and the dismounting between the upper bracket of the air spring and the frame 200 are convenient, and the maintenance and the replacement difficulty are reduced.

In this embodiment, in order to ensure the firmness of the connection between the support plate 2 and the frame 200, the first mounting holes 211 are provided with two, and the two first mounting holes 211 are arranged along the horizontal plane at intervals, so that the mounting and the dismounting are convenient.

Further, the main plate 21 is perpendicular to the bottom plate 1, that is, the air spring 100 is perpendicular to the frame 200, so that the mounting bolt 210 only bears the vertical load between the frame 200 and the air spring 100, which is beneficial to improving the service life of the mounting bolt 210 and ensuring the connection effectiveness.

Alternatively, the shape of the bottom plate 1 is circular to fit the outer shape of the air spring 100, and in other embodiments, the bottom plate 1 may also be triangular or quadrangular, which is not limited herein.

In order to realize the connection between the bottom plate 1 and the air spring 100, a second mounting hole 11 is formed in the bottom plate 1, the air spring 100 is provided with a connecting column 120, and a buckle 122 and a clamping groove capable of being clamped with the buckle 122 are formed in the end portion of the connecting column 120. During connection, the connecting column 120 penetrates through the second mounting hole 11, and then the buckle 122 is clamped in the clamping groove, so that connection between the bottom plate 1 and the air spring 100 is realized. Preferably, a gasket 123 is padded between the buckle 122 and the bottom plate 1, the upper surface of the gasket 123 is abutted against the buckle 122, and the lower surface of the gasket 123 is abutted against the bottom plate 1, so that the shaking between the connecting column 120 and the upper bracket of the air spring is reduced. Alternatively, the clip 122 is a snap spring, and those skilled in the art can select a snap spring with suitable parameters according to the sizes of the connecting column 120 and the snap groove to ensure the reliability of the connection between the base plate 1 and the air spring 100.

Further, second mounting hole 11 is located the one side that mainboard 21 was provided with pterygoid lamina 22, and for the installation and the dismantlement of buckle 122 and joint groove, pterygoid lamina 22 and the planar contained angle in mainboard 21 place are the acute angle, provide great operating space for the installation and the dismantlement in buckle 122 and joint groove, make the operation more convenient.

Specifically, the flat plate 31 is provided with the mounting notch 311 facing the second mounting hole 11, so that the interference between the flat plate 31 and the connecting column 120 can be avoided while the connection strength between the second mounting hole 11 and the concave structure 110 is ensured.

Preferably, in order to reduce the weight of the air spring upper bracket, the side of wing plate 22 far away from main plate 21 is set as inclined edge 221, that is, the width of the end of wing plate 22 connected with bottom plate 1 is greater than the width of the end of wing plate 22 far away from bottom plate 1, which not only enhances the connection firmness of support plate 2, but also reduces the weight of the air spring upper bracket.

In this embodiment, the main plate 21 and the wing 22 are integrally formed, and the vertical plate 32 and the flat plate 31 are integrally formed, which is beneficial to ensuring the strength between the main plate 21 and the wing 22, and between the vertical plate 32 and the flat plate 31. Specifically, the supporting plate 2 and the reinforcing plate 3 are both made of metal plate through bending and stamping.

Further, the vertical arrangement of the vertical plates 32 and the flat plates 31, and the parallel arrangement of the flat plates 31 and the bottom plate 1, facilitate the vertical plates 32 to bear larger vertical loads from the air spring 100, and also facilitate the processing of the reinforcing plate 3.

Preferably, the flat plate 31 is further provided with a rib plate 33 to reinforce the connection strength between the bottom plate 1 and the support plate 2, and effectively prevent the reinforcing plate 3 from being extruded and deformed during use. The rib plate 33 is positioned between the two vertical plates 32, so that the stress of the flat plate 31 is more uniform. In order to improve the bearing capacity of the rib plates 33 on the vertical load of the air spring 100, the rib plates 33 are arranged perpendicular to the bottom plate 1.

In this embodiment, between mainboard 21 and the bottom plate 1, between riser 32 and the bottom plate 1, all weld between gusset 33 and the bottom plate 1, be convenient for make respectively and process of bottom plate 1, backup pad 2 and reinforcing plate 3, reduce the processing degree of difficulty, and welding operation is simple, firm in connection.

The embodiment also discloses an air suspension of an automobile chassis, which comprises the air spring upper bracket in any scheme.
