[0029] See also Figure 2-3In order to facilitate the fixing of the exoskeleton 3 and the rubber ring 2, the fixing mechanism 4 in this embodiment includes six sliders 41, two rubber blocks 42, six telescopic rods 43, six return springs 44, six drive plates 45 and six clamping rods 46. The six sliders 41 are evenly fixed on the upper and lower ends of the outer surface of the rubber ring 2. The upper and lower ends of the left side of the exoskeleton 3 are provided with sliding grooves 47. The side of the rubber ring 2 away from the rubber block 42 can be inserted into the inner cavity of the exoskeleton 3, so that the six sliders 41 are opened at the upper and lower ends of the inner cavity of the exoskeleton 3. The inner cavity of the slide groove 47 slides to the right, and the two rubber blocks 42 are fixed to the upper and lower ends of the left side of the rubber ring 2. The telescopic rod 43 is fixed to the inner back wall of the slide groove 47. The return spring 44 is movably sleeved on the outer surface of the telescopic rod 43. The driving plate 45 is fixed to the other end of the telescopic rod 43. The clamping rod 46 is fixed to the side of the driving plate 45 away from the telescopic rod 43. When the slider 41 slides, it squeezes the clamping rod 46, causing the clamping rod 46 to move forward, thereby causing the driving plate 45 to move, which can squeeze the telescopic rod 43 and the return spring 44.

[0030] In this embodiment, the size of the inner cavity of the slide groove 47 is adapted to the size of the slider 41, the slider 41 performs horizontal linear motion in the inner cavity of the slide groove 47, the size of the rubber block 42 is adapted to the size of the inner cavity of the slide groove 47, and the two ends of the return spring 44 are respectively fixedly connected to the driving plate 45 and the side opposite to the inner back wall of the slide groove 47.

[0031] Among them, the telescopic rod 43 includes a fixed rod and an inner rod nested with each other, a through hole is opened on the front of the slider 41, the inner diameter of the through hole is adapted to the outer diameter of the clamping rod 46, the size of the driving plate 45 is the same as the inner diameter of the through hole, and a clamping groove is opened on the inner front wall of the slide groove 47, and the inner diameter of the clamping groove is adapted to the outer diameter of the clamping rod 46.

[0032] It can be understood that until the rubber ring 2 moves to the rightmost side of the slide groove 47, the clamping rod 46 can be aligned with the through hole and the clamping groove provided on the surface of the slider 41. At this time, the return spring 44 is not squeezed and rebounds to drive the telescopic rod 43 and the driving plate 45 to move, so that the clamping rod 46 passes through the through hole to the clamping groove, the slider 41 can be limited, and then the rubber ring 2 can be fixed to the outer frame 3, and then the rubber ring 2 can be fixed to the outer surface of the core 1 with adhesive.

[0033] It should be noted that the fixing mechanism 4 can facilitate the staff to fix the rubber ring 2 and the outer frame 3, which not only improves the fixing efficiency, but also reduces the contact between the adhesive and the hand, and further improves the torsional stiffness and fatigue resistance of the bushing.

[0034] See also Figure 4In order to improve the waterproof and aging resistance of the bushing, the wear-resistant mechanism 5 in this embodiment includes an adhesive layer 51, a waterproof layer 52 and an aging resistance layer 53. The adhesive layer 51 is arranged on the outside of the core 1, and the waterproof layer 52 is arranged on the outside of the adhesive layer 51.

Chemlock is a universal single-coat or double-coat rubber and metal thermal adhesive that can bond a variety of rubber and metal substrates through vulcanization. The aging-resistant layer 53 is a fluororubber layer. The aging-resistant layer 53 is a fluororubber layer. Fluororubber refers to a synthetic polymer elastomer containing fluorine atoms on the carbon atoms of the main chain or side chain. The introduction of fluorine atoms gives the rubber excellent heat resistance, oxidation resistance, oil resistance, corrosion resistance and atmospheric aging resistance.

[0036] The working principle of the above embodiment is:

[0037] (1) When fixing the rubber ring 2 and the outer frame 3, the side of the rubber ring 2 away from the rubber block 42 can be inserted into the inner cavity of the outer frame 3, so that the six sliders 41 slide to the right in the inner cavity of the slide groove 47 opened at the upper and lower ends of the inner cavity of the outer frame 3. When the slider 41 slides, it squeezes the clamping rod 46, so that the clamping rod 46 moves forward, and then the driving plate 45 moves. The telescopic rod 43 and the return spring 44 can be squeezed until the rubber ring 2 moves to the rightmost side of the slide groove 47, and the clamping rod 46 can be aligned with the through hole and the clamping groove opened on the surface of the slider 41. At this time, the return spring 44 is not squeezed and rebounds and drives the telescopic rod 43 and the driving plate 45 to move, so that the clamping rod 46 passes through the through hole into the clamping groove, and the slider 41 can be limited. Then, the rubber ring 2 and the outer frame 3 can be fixed, and then the rubber ring 2 can be fixed to the outer surface of the core 1 using an adhesive.

Fluororubber refers to a synthetic polymer elastomer containing fluorine atoms on the carbon atoms of the main chain or side chain. The introduction of fluorine atoms gives the rubber excellent heat resistance, oxidation resistance, oil resistance, corrosion resistance and atmospheric aging resistance.
