DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 5 , an internal bogie air spring, comprising an upper fixed seat 1 and a lower fixed seat 2, a capsule 3 is fixedly installed between the upper fixed seat 1 and the lower fixed seat 2, and multiple groups of supporting components are installed on the upper fixed seat 1 and the lower fixed seat 2;

[0024] The support assembly includes two mounting blocks 4 respectively fixedly mounted on the upper fixing seat 1 and the lower fixing seat 2, and two support rods 5 respectively rotatably mounted on the two mounting blocks 4;

[0025] An elastic ring 6 is sleeved on the capsule 3, and the ends of the plurality of support rods 5 away from the mounting block 4 are rotatably connected to the elastic ring 6. An annular elastic cloth 7 is sleeved on the capsule 3, and the upper and lower ends of the elastic cloth 7 are respectively mounted on the upper fixing seat 1 and the lower fixing seat 2 through connecting components.

[0026] When the capsule 3 is deformed, the two struts 5 in the supporting assembly will be driven to rotate, and the end of the strut 5 away from the mounting block 4 will be away from the capsule 3, thereby driving the elastic ring 6 to deform through the multiple groups of struts 5 in the supporting assembly, and the diameter of the elastic ring 6 will increase. Then, under the support of the elastic ring 6, the elastic cloth 7 will be driven to deform, thereby ensuring that the elastic cloth 7 can always wrap the capsule 3 without affecting the operation of the capsule 3. The protection of the elastic cloth 7 can effectively prevent stones from impacting the capsule 3 and prevent the capsule 3 from being damaged, thereby reducing the safety hazards existing in the running of the motor vehicle.

[0027] The connecting assembly includes a connecting ring 8 fixedly mounted on the elastic cloth 7, a plurality of connecting blocks 9 fixedly mounted on the connecting ring 8, and a locking component for locking the connecting block 9 and the mounting block 4. The plurality of connecting blocks 9 are respectively in contact with the plurality of mounting blocks 4. A positioning hole is provided on the connecting block 9. The locking component includes two L-shaped support blocks 10 respectively fixedly mounted on both side surfaces of the mounting block 4, two spring rods 11 respectively fixedly mounted on the two support blocks 10, and two positioning blocks 12 respectively fixedly mounted on one end of the two spring rods 11. The two positioning blocks 12 are respectively inserted at both ends of the positioning hole.

[0028] The elastic cloth 7 is mounted on the air spring by mounting the connecting ring 8 on a plurality of mounting blocks 4, inserting one end of the positioning block 12 into the positioning hole on the connecting block 9, thereby mounting the connecting block 9 on the mounting block 4;

[0029] When the elastic cloth 7 is damaged and needs to be removed and replaced, the staff can drive the two positioning blocks 12 on the mounting block 4 away from each other, compress the spring rod 11, and pull one end of the positioning block 12 out of the positioning hole, thereby removing the connecting block 9 from the mounting block 4, until all the connecting blocks 9 are removed from the mounting block 4, and the removal of the elastic cloth 7 is completed.

[0030] A shift block 15 is fixedly installed on the upper surface of the positioning block 12, and an anti-skid pad is fixedly installed on the shift block 15. The anti-skid pad is made of rubber. When it is necessary to move the positioning block 12, the shift block 15 can be moved to drive the positioning block 12 to move. The anti-skid pad can prevent slipping when the shift block 15 is moved.

[0031] A mounting post 13 is fixedly mounted on the elastic ring 6, and a threaded groove is provided on the mounting post 13. A plurality of through holes are provided on the elastic cloth 7. A screw 14 is provided on the mounting post 13, and one end of the screw 14 passes through the through hole and is inserted into the threaded groove. When the elastic cloth 7 is sleeved on the capsule 3, the middle part of the elastic cloth 7 is fixedly mounted on the elastic ring 6 by the plurality of screws 14 and the plurality of mounting posts 13, and the fixed parts are arranged equidistantly on the elastic ring 6. When the elastic ring 6 is deformed, the surface of the elastic cloth 7 is uniformly deformed, so as to prevent the elastic cloth 7 from being damaged due to excessive deformation at a local position.

[0032] The elastic cloth 7 is a nylon stretch cloth, which is a mixture of nylon, spandex and other fibers, has good elasticity and wear resistance, and has a better protective effect on the capsule 3.

[0033] In the utility model, when the capsule 3 is deformed, the support rod 5 in the support assembly will drive the elastic ring 6 to deform, and the diameter of the elastic ring 6 will increase. Then, under the support of the elastic ring 6, the elastic cloth 7 will be driven to deform, thereby ensuring that the elastic cloth 7 can always wrap the capsule 3 without affecting the operation of the capsule 3. The protection of the elastic cloth 7 can effectively prevent stones from impacting the capsule 3 and prevent the capsule 3 from being damaged, thereby reducing the safety hazards existing in the driving process of the motor vehicle.

[0034] In general, regarding the technical problem: when the train is running on the track, stones on the track may splash onto the capsule 3, thereby damaging the capsule 3 and making it unusable, resulting in a safety hazard of movement during the running of the train; a technical solution is adopted: the capsule 3 can be wrapped by the cooperation of the mounting block 4, the strut 5, the elastic ring 6, the connecting assembly and the elastic cloth 7; because the implementation process of the technical solution is: when the capsule 3 is deformed, the strut 5 in the supporting assembly will drive the elastic ring 6 to deform, and the diameter of the elastic ring 6 will increase, and then under the support of the elastic ring 6, the elastic cloth 7 will be driven to deform, thereby ensuring that the elastic cloth 7 can always wrap the capsule 3 without affecting the operation of the capsule 3, and the protection of the elastic cloth 7 can effectively prevent stones from impacting the capsule 3; so the technical problem can definitely be solved, and the technical effect achieved is: preventing the capsule 3 from being damaged, thereby reducing the safety hazard during the running of the train.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
