Wherein, the connecting bracket 300 can be connected with the bushing inner tube 221, and the cylindrical portion 211 can be installed with the bushing outer tube 223 in an interference fit. For ease of manufacture and assembly, the bushing inner tube 221, the rubber main spring 222, and the bushing outer tube 223 may be vulcanized together.

Here, in order to save the arrangement space, the present disclosure improves the structure of the connection bracket 300, and by the rational arrangement and assembly of the suspension body 200 and the connection bracket 300, the maximum utilization of the existing arrangement space can be achieved. For example, in one embodiment, referring to fig. 1 and 2, the connecting bracket 300 may be configured as a plate-shaped structure extending along the vehicle X direction, so that the occupied space in the Y direction may be saved, which is beneficial to the structural design and arrangement of the suspension body 200. Referring to fig. 9, the plate-shaped structure may have a powertrain connecting portion 310 at the front end and a suspension body connecting portion 320 at the rear end, the powertrain connecting portion 310 may realize a fixed connection with a powertrain, and may include the powertrain mounting holes, and the number of the powertrain mounting holes may be multiple, so as to ensure the connection strength; the suspension body connection part 320 may accordingly achieve a fixed connection with the suspension body 200, and may include a pair of U-shaped protrusions 321 formed at left and right sides of the plate-shaped structure, respectively, and two U-shaped protrusions of the pair of U-shaped protrusions 321 may be disposed opposite to each other in front and rear. That is, a pair of U-shaped protrusions 321 is formed on the left and right sides of the plate-shaped structure, the two U-shaped protrusions 321 on each side are oppositely opened in the front-rear direction, and the bushing inner tubes 221 on both sides can be respectively embedded between the pair of U-shaped protrusions 321 on the corresponding side, so as to connect the connecting bracket 300 and the suspension body 200.
