The mounting portion is embodied as a mounting hole 102 formed in a mounting frame, the external carrier is embodied as a vehicle body, and the suspension structure is mounted on the vehicle body through the mounting hole 102.

As shown in fig. 4 in combination with fig. 1, the frame 2 of the present embodiment is embedded in the rubber body 3 and is vulcanized with the rubber body 3, and two ends of the frame 2 are extended from the rubber body 3. Meanwhile, a radially outward-protruding rigid support portion wrapped in the following limiting portion 303 is provided on the frame 2, and a second connecting portion for connecting with an external member, specifically, a trailing arm connected with an engine, is configured on the frame 2. As shown in fig. 4, the frame 2 is generally cylindrical, and the second connecting portion is a connecting hole 201 penetrating through the frame 2 in the length direction.

As shown in fig. 5 in combination with fig. 4, the rigid support portion is a support ring 4 sleeved outside the framework 2 and fixedly connected with the framework 2, and during specific assembly, the framework 2 is pressed in the support ring 4. At this time, in order to facilitate the press-fitting, as shown in fig. 5, process grooves 401 penetrating in the axial direction of the support ring 4 are configured on the outer circumferential surface of the support ring 4, and the process grooves 401 are specifically two that are provided at intervals in the circumferential direction of the support ring 4.
