In order to achieve the purpose, the utility model adopts the technical scheme that: a novel suspension assembly structure comprises a suspension device, a main spring, a collision block, a stud bolt and an outer framework; the main spring comprises an inner core, an outer pipe and an inner layer rubber block positioned between the inner core and the outer pipe; stud bolts are embedded in the inner core; the collision block comprises a limiting framework and an outer layer rubber block wrapping the limiting framework; a through hole for the stud to pass through is formed in the limiting framework, and the main spring of the limiting framework is limited and fixed through a locking nut; the exoskeleton is fixed to the outer layer of the whole suspension device.

Further, outer rubber block parcel is outer at whole spacing skeleton, and outer rubber block bottom is provided with the arc wall.

Furthermore, a certain cavity is reserved on the connecting position surface of the inner layer rubber block and the outer layer rubber block, so that the elastic damping effect can be achieved.

Furthermore, an embedding groove is formed in the inner pipe surface of the inner core; an arc-shaped boss is arranged at the position where the stud bolt is connected with the inner core in an embedded manner; the arc-shaped boss is fixedly matched and connected with the embedding groove.

The utility model has the beneficial effects that: according to the utility model, the single-head bolt for connecting the main spring and the collision block is replaced by the stud bolt, and when the stud bolt embedded in the inner core of the main spring is installed on the side bracket of the suspension and the power assembly, the bolt and the suspension cannot rotate along with the stud bolt, so that the problems of inconvenient installation and inconvenient part replacement of the single-head bolt are solved, and the use is very convenient. Under the condition of meeting the product performance and the assembly space, the number of tools required by installation is reduced, the difficulty of installation and after-sale replacement is reduced, the production cost is saved, the production efficiency is improved, and the original characteristics of the product are ensured.
