DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0016] Refer to Figure 1 , a device for increasing the stiffness of a shock absorber, including an air spring airbag 7 and an upper coiled plate 4 and a lower coiled plate 10 respectively connected to the upper and lower ends of the air spring airbag 7. An upper support steel disc 6 is provided at the upper end of the air spring airbag 7, and a lower support steel disc 8 is provided at the lower end. The upper support steel disc 6 is closely fixed and covered on the upper coiled plate 4 and the upper end of the air spring airbag 7, so that the inner side of the upper support steel disc 6 is respectively in close contact with the top of the upper coiled plate 4 and the upper circumference of the air spring airbag 7. The lower support steel disc 8 is closely fixed and covered on the lower coiled plate 10 and the lower end of the air spring airbag 7, so that the inner side of the lower support steel disc 8 is respectively in close contact with the top of the lower coiled plate 10 and the lower circumference of the air spring airbag 7. When the air spring shock absorber connected to the equipment moves horizontally, the lateral stiffness can be increased by the circumferential close contact between the upper support steel disc 6 and the lower support steel disc 8 and the air spring airbag 7, the sway amplitude of the connected equipment in the horizontal direction can be reduced, and further the risk of the connected equipment tipping over can be reduced, and the safety performance can be improved.

[0017] A first rubber sealing ring 5 is provided at the contact position between the upper coiled plate 4, the upper support steel disc 6 and the air spring airbag 7, and a second rubber sealing ring 9 is provided at the contact position between the lower coiled plate 10, the lower support steel disc 8 and the air spring airbag 7. The setting of the rubber sealing ring facilitates the sealing of the small gaps generated during the installation of the upper support steel disc 6 and the lower support steel disc 8 and the air spring airbag 7, and further improves the lateral stiffness of the air spring.

[0018] A stud 1 is vertically provided at the center of the upper coiled plate 4. A through hole for the stud 1 to pass through is provided in the middle of the upper support steel disc 6. The upper support steel disc 6 is fixed on the upper coiled plate 4 by a nut 2, which is convenient for the disassembly and assembly of the upper support steel disc 6.

[0019] A first lock washer 3 is sleeved on the stud 1 between the upper support steel disc 6 and the nut 2, which can prevent the nut 2 from loosening when the air spring shakes horizontally.

[0020] A plurality of through holes are spacedly provided on the lower coiled plate 10. A plurality of nuts 13 with closed tops are provided on the upper side of the lower coiled plate 10. The plurality of nuts 13 respectively cover and seal outside the plurality of through holes. The lower support steel disc 8 is fixedly connected to the plurality of nuts 13 by a plurality of bolts 11, which is convenient for the disassembly and assembly of the lower support steel disc 8.

[0021] A second lock washer 12 is sleeved on each of the plurality of bolts 11, which can prevent the bolts 11 from loosening when the air spring shakes horizontally.

[0022] Working principle: When the air spring bears an excessive lateral load and a large displacement occurs at point A relative to point B, the upper support steel disc 6 and the lower support steel disc 8 simultaneously play a role in laterally supporting the air spring, thereby realizing the improvement of the air spring stiffness.
