Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, unless otherwise stated, the use of the directional terms such as "up" and "down" generally refers to up and down of the vehicle during normal driving, specifically, the direction pointing to the ceiling of the vehicle is up, and the direction pointing to the chassis of the vehicle is down, and as shown by referring to the drawing direction of fig. 1, "inside and outside" refers to inside and outside of the corresponding structure, "far and near" refers to far and near from the corresponding structure.

Referring to fig. 1-5, according to a first aspect of the present disclosure, there is provided an air spring shock absorber assembly 1, comprising an air spring assembly 10, the air spring assembly 10 including an upper support structure 11, a piston 12, outer protecting tube 13 and gasbag 14, the upper end of gasbag 14 is connected with last bearing structure 11, the lower extreme and the piston 12 of gasbag 14 are connected, be formed with the air chamber 110 with the inside intercommunication of gasbag 14 in going up bearing structure 11, outer protecting tube 13 covers the outside at least partial gasbag 14, the surface of gasbag 14 can be in the inside atmospheric pressure effect of gasbag 14 and the surface laminating of the surface of piston 12 and outer protecting tube 13, outer protecting tube 13 has at least one protecting tube convergent section 131 and at least one protecting tube divergent section 132, the internal diameter of protecting tube convergent section 131 reduces along the direction from top to bottom gradually, the internal diameter of protecting tube divergent section 132 increases along the direction from top to bottom gradually.

Through the above technical solution, during the vehicle running, when the vehicle bumps, the piston 12 moves towards the direction approaching to the upper supporting structure 11 or away from the upper supporting structure 11, during the movement of the piston 12, because the lower end of the air bag 14 is connected with the piston 12, the piston 12 can drive the air bag 14 with certain flexibility to curl, so that the volume of the air inside the air bag 14 changes, thereby generating the elastic action, and because the outer protection tube 13 is covered on the outside of the air bag 14, and the outer protection tube 13 has a protection tube tapered section 131 with an inner diameter gradually decreasing along the direction from top to bottom and a protection tube tapered section 132 with an inner diameter gradually increasing along the direction from top to bottom, during the process that the piston 12 drives the air bag 14 to curl, the diameter a of the outline of the area where the air bag 14 contacts with the outer protection tube 13 can always change, that is, the change rate of the diameter a of the outline of the area where the air bag 14 contacts with the outer protection tube 13 is also a change value, therefore, the rigidity of the air spring assembly 10 is variable, the performance of the air spring can better meet the requirement of vibration reduction, and the vibration reduction capability of the suspension during driving on uneven roads is improved.

To further increase the stiffness variation of air spring assembly 10, as shown in fig. 2, 4, and 5, can optionally, can shield tapered section 131 can include a first shield tapered section 1310 and a second shield tapered section 1320, with shield tapered section 132 formed between first shield tapered section 1310 and second shield tapered section 1320. That is, the outer shroud 13 may include a first shroud tapered section 1310, a shroud diverging section 132, and a second shroud tapered section 1320.

Taking the design height of the air spring shock absorber assembly, i.e. the vehicle is in a half-load state (1-2), as shown in fig. 5, when the vehicle runs on a relatively gentle road surface, the lower end of the air bag 14 is attached to a part of the gradually expanding section 132 of the protecting tube, when the air spring assembly 10 stretches (i.e. the piston 12 moves downwards) and drives the lower end of the air bag 14 to move downwards, the contact area between the lower end of the air bag 14 and the gradually expanding section 132 of the protecting tube 13 increases, and the inner diameter of the gradually expanding section 132 of the protecting tube gradually increases along the direction from top to bottom, so the diameter a of the contour of the area where the outer protecting tube 13 contacts the air bag 14 increases during stretching; when air spring assembly 10 is compressed (i.e., piston 12 moves upward) and moves the lower end of bladder 14 upward, the contact area between the lower end of bladder 14 and shroud diverging section 132 decreases, and the inner diameter of shroud diverging section 132 decreases in the bottom-to-top direction, so that the profile of the area where shroud diverging section 132 contacts bladder 14 decreases in diameter a when stretched; because the change of the diameter A of the outline of the contact area of the outer protective sleeve 13 and the air bag 14 is a change value in the stretching and compressing processes of the air spring assembly 10, and the change of the compression amount and the stretching amount of the air spring assembly 10 when the vehicle runs on a gentle road surface is small, the air spring assembly 10 can have a moderate rigidity value, and the vehicle can meet the requirement of better smoothness.

As shown in fig. 4, taking the air spring damper assembly as an example, when the vehicle is under a large compression condition, the lower end of the air bag 14 is attached to a portion of the first tapered sheath section 1310, and when the air spring assembly 10 is compressed (i.e., the piston 12 moves upward) and drives the lower end of the air bag 14 to move upward, the contact area between the lower end of the air bag 14 and the first tapered sheath section 1310 decreases, and the inner diameter of the first tapered sheath section 1310 increases from bottom to top, so the diameter a of the contour of the area where the first tapered sheath section 1310 contacts the air bag 14 increases when compressed, and when the air spring assembly 10 is stretched (i.e., the piston 12 moves downward) and drives the lower end of the air bag 14 to move downward, the contact area between the lower end of the air bag 14 and the first tapered sheath section 1310 increases, and the inner diameter of the first tapered sheath section 1310 decreases from top to bottom, therefore, the diameter a of the contour of the region where the first casing tapered section 1310 contacts with the air bag 14 is reduced in compression, that is, the diameter a of the contour of the region where the first casing tapered section 1310 contacts with the air bag 14 is a variable value no matter the air spring assembly 10 is under tension or compression, so that the stiffness of the air spring assembly 10 under a large compression stroke is changed more, and the handling stability of the vehicle under the conditions of sudden acceleration and the like of the suspension is improved.

As shown in fig. 1-2, in the case that the air spring damper assembly is far from its designed height, i.e., in the case of a vehicle under a large tension, the lower end of the air bag 14 is attached to a portion of the second casing tapered section 1320, when the air spring assembly 10 is compressed (i.e., the piston 12 moves upward) and drives the lower end of the air bag 14 to move upward, the contact area between the lower end of the air bag 14 and the second casing tapered section 1320 is reduced, while the inner diameter of the second casing tapered section 1320 is gradually increased from bottom to top, so that the diameter a of the contour of the area where the second casing tapered section 1320 contacts the air bag 14 is increased when compressed, and when the air spring assembly 10 is stretched (i.e., the piston 12 moves downward) and drives the lower end of the air bag 14 to move downward, the contact area between the lower end of the air bag 14 and the second casing tapered section 1320 is increased, and the inner diameter of the second tapered sheath section 1320 is gradually reduced from top to bottom, so that the diameter a of the profile of the region where the second tapered sheath section 1320 contacts the airbag 14 is reduced when being compressed, that is, no matter the air spring assembly 10 is under tension or compression, the diameter a of the profile of the region where the first tapered sheath section 1310 contacts the airbag 14 is a variable value, so that the air spring assembly 10 has a greater variable stiffness under a large tension stroke, and the handling stability of the vehicle under the working conditions of turning and the like of the suspension is improved.

In one embodiment provided by the present disclosure, optionally, as shown in fig. 1, 2, 4, and 5, the first casing tapered section 1310, the casing diverging section 132, and the second casing tapered section 1320 collectively comprise a dog-leg structure.

In summary, the present disclosure does not limit the structural shape of the first casing tapered section 1310, the casing tapered section 132, and the second casing tapered section 1320, as long as it can achieve that the diameter a of the contour of the area of the airbag 14 contacting the outer casing 13 is always in a changing state during the stretching or compressing of the airbag 14.

Therefore, in the process of compressing or stretching the air bag 14 by the piston 12, the diameter of the outline of the area of the air bag 14 contacted with the outer surface of the piston 12 (namely the piston gradually-expanding section 121 or the piston gradually-reducing section 122) is always in a changed state, and the volume of the air bag 14 is adjusted together with the outer protective sleeve 13, so that the smoothness of the vehicle in the process of traveling on a gentle road surface is improved.
