[0002] Automobile suspension is a crucial component for ensuring ride comfort. Furthermore, as the force-transmitting mechanism connecting the vehicle frame and axles, it is crucial for ensuring vehicle safety. Therefore, suspension is often listed as a key component in a car's technical specifications, serving as a quality indicator.

[0003] The existing support arms cannot adjust the length and angle of the support arms at will, which limits the flexible application and adaptability of the support arms under different working conditions and cannot provide optimal support and comfort under complex road conditions or heavy load conditions. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a support arm for independent suspension of buses, which avoids the problem that the existing support arm cannot adjust the length and angle of the support arm at will, limits the flexible application and adaptability of the support arm under different working conditions, and cannot provide optimal support and comfort under complex road conditions or heavy load conditions.

[0005] In order to solve the above technical problems, the present invention provides a technical solution as follows: a support arm for an independent suspension of a passenger car, comprising a support arm body, a lower support arm fixedly connected to the lower portion of the support arm body, a first mounting hole provided at the lower portion of the lower support arm, two upper support arm structures connected to the upper portion of the support arm body, a fixing column fixed to the upper end of each of the two upper support arm structures, a second mounting hole provided on the upper portion of each of the two fixing columns, and a transverse arm structure fixedly connected to the interior of the two upper support arm structures;

[0006] The upper support arm structure includes a support sleeve plate that is slidably connected to the upper part of the support arm body, a cavity is provided inside the support sleeve plate, a support column is slidably connected inside the support sleeve plate, the support sleeve plate is fixed to the support column by bolts, and a connecting plate is fixed to one side of the lower part of the support sleeve plate.

[0007] As an improvement, a threaded hole is provided on one side of the upper portion of the support arm body close to the connecting plate, and the support arm body and the connecting plate are fixedly connected by bolts.

[0008] As an improvement, a plurality of threaded holes are provided on the upper portion of the support arm body, and the support arm body is fixedly connected to the support sleeve plate by bolts.

[0009] As an improvement, the cross arm structure includes ear seat 1 and ear seat 2 fixed on both sides of the two supporting sleeves, and the ear seat 1 and ear seat 2 are respectively rotatably connected with rotating plate 1 and rotating plate 2 inside, and a connecting rod is fixedly connected between rotating plate 1 and rotating plate 2 by bolts.

[0010] As an improvement, sliding grooves are provided inside the rotating plate 1 and the rotating plate 2.

[0011] As an improvement, a through hole is provided at the axis center of the support arm body.

[0012] The advantages of the present invention over the prior art are that the angle and length of the support arm are adjusted through the upper support arm structure, thereby avoiding the problem that the existing support arm cannot arbitrarily adjust the length and angle of the support arm, which limits the flexible application and adaptability of the support arm under different working conditions and cannot provide optimal support and comfort under complex road conditions or heavy load conditions.
