[0030] Example 1

[0031] This embodiment provides a combined suspension guide arm, which includes a front arm body 1 and a rear arm body 2. The rear part of the front arm body 1 and the front part of the rear arm body 2 are respectively provided with a front clamp and a rear clamp. The front clamp and the rear clamp form an axle mounting hole, and the axle mounting hole is used to insert the axle; the front clamp and the rear clamp are connected in a detachable manner.

[0032] The aforementioned combined suspension guide arm, with the front arm body 1 and rear arm body 2 manufactured separately, can reduce the difficulty of manufacturing the suspension guide arm and also facilitate replacement and maintenance of the front arm body 1 or rear arm body 2. Furthermore, the front and rear clamps form an axle mounting hole, allowing staff to adjust the distance between the front and rear clamps as needed, thereby adjusting the size of the axle mounting hole, making the combined suspension guide arm adaptable to different axle models. Furthermore, the above-mentioned front clamp and rear clamp are connected in an open and detachable manner, and the detachable manner can be any existing manner such as bolt 4 connection, clamping, etc. The connection between the front arm body 1 and the rear arm body 2 can also be connected through the connection between the front clamp and the rear clamp. This method also makes it convenient to install the axle in the axle mounting hole surrounded by the front clamp and the rear clamp. When the size of the axle changes, it is only necessary to adjust the gap between the front clamp and the rear clamp. The above-mentioned setting makes it easy to adjust the tightness of the fit between the axle and the axle mounting hole. For example, when the size of the axle changes, the distance between the front clamp and the rear clamp can be adjusted to make the front clamp and the rear clamp clamp tightly around the axle.

[0033] Specifically, in this embodiment, when the cross-section of the axle is a quadrilateral such as a square, in order to form an axle mounting hole with a square or rectangular cross-section, the front clamp and the rear clamp both include L-plates, and the two L-plates are buckled together to form the axle mounting hole.

[0034] More specifically, in this embodiment, in order to connect the front clamp and the rear clamp, both ends of the L-plate are provided with outwardly extending folding plates 3, and the folding plates 3 are provided with mounting holes; the folding plates 3 of the front clamp and the rear clamp are symmetrically arranged and connected by bolts 4 passing through the mounting holes.

[0035] Specifically, the L-plate comprises a transverse plate 6 and a vertical plate 5. At least one of the vertical plates 5 of the front and rear hoop is equipped with an extension plate 7 extending in the direction of the axle, which is in contact with the axle. On the combined suspension guide arm, the extension plate 7 is in contact with the axle, providing support and increasing the connection strength between the axle and the combined suspension guide arm. The extension plate also secures the axle at the front or rear, preventing it from shifting forward or backward.

[0036] Specifically, in this embodiment, the folding plate serves as the bending plate at both ends of the L-plate and plays a major connecting role. In order to improve the connection strength between the folding plate and the L-plate, reinforcing plates 8 are provided at the bending parts of the folding plate and the L-plate, and the reinforcing plates 8 respectively connect the folding plate and the L-plate.

[0037] More specifically, since an angle is formed between the folding plate and the L-plate, a reinforcing plate 8 is provided at the angle. The reinforcing plate 8 is provided in a triangular shape, and two reinforcing edges of the reinforcing plate 8 respectively adhere to and fix the folding plate and the L-plate.

[0038] More specifically, extension plates 7 are provided at both ends of the vertical plate 5 .

[0039] More specifically, to further enhance the connection strength between the axle and the combined suspension guide arm, the extension plate 7 has transverse edges extending in the direction of the axle's extension, and these transverse edges are welded to the axle. It should be noted that the extension plate adheres to the front or rear side of the axle, and the transverse edges are also welded to the front or rear side of the axle. This approach avoids welds on the upper or lower end surfaces or transverse surfaces of the axle, thereby preventing any impact on the mechanical properties of the axle.

[0040] More specifically, the L-plate includes a transverse plate 6 and a vertical plate 5. An extension plate 7 is provided on the vertical plate 5. The extension plate 7 fits the axle, and the extension plate 7 and the axle are connected by welding.

[0041] Specifically, in this embodiment, the rear arm 2 is provided with an airbag mounting seat.

[0042] Of course, the above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention and should be protected by the present invention.
