Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, a further description of aspects of the present disclosure will be provided below. It should be noted that, without conflict, the embodiments of the present disclosure and features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the disclosure.
As shown in fig. 1 to 3, the present embodiment provides an air spring damper assembly including a damper liquid reservoir 1, a spring tray 2, an elastic washer 3, an air spring piston 4, and an annular seal ring 6. Wherein, spring tray 2 cover is established and is connected in shock absorber liquid storage cylinder 1, and spring tray 2 is the frustum structure. The elastic washer 3 is sleeved and pressed on the spring tray 2. The air spring piston 4 is sleeved on the shock absorber liquid storage cylinder, the inner wall surface of the air spring piston 4 comprises a first conical surface 41, and the first conical surface 41 is abutted against the elastic washer 3. The annular sealing ring 6 is sleeved on the shock absorber liquid storage cylinder and is clamped between the shock absorber liquid storage cylinder 1 and the air spring piston 4.
It can be understood that the spring tray 2 is in a frustum-shaped structure, the spring tray 2 is sleeved on the shock absorber liquid storage cylinder 1 and is connected with the shock absorber liquid storage cylinder 1, the elastic gasket 3 presses on the spring tray 2 by means of self elasticity, and the first conical surface 41 of the air spring piston 4 presses on the elastic gasket 3. When the torsional moment brought by the stabilizer bar is connected to the lower end of the shock absorber, under the action of the air spring internal pressure of the spring tray 2 and the elastic gasket 3, the friction moment generated by the load on the air spring piston 4 acting on the elastic gasket 3 is larger than the torque friction force of the simple annular sealing ring 6 in the prior art, so that abnormal sound caused by sliding of the air spring and the shock absorber can be reduced or even eliminated.
The elastic washer 3 is pressed against the spring tray 2 by its own elastic force. It can be appreciated that the elastic washer 3 has the capability of elastic expansion, the elastic washer 3 is sleeved on the spring tray 2 by utilizing the capability of elastic expansion of the elastic washer 3, and the elastic washer 3 is tightly sleeved on the spring tray 2 under the elastic action of self-restoring state.
Optionally, the elastic washer 3 is made of rubber. The elastic washer 3 made of rubber has the performances of oil resistance, acid and alkali resistance, cold and heat resistance, aging resistance and the like, can ensure that the friction force between the air spring piston 4 and the elastic washer 3 is kept relatively stable, and prolongs the service life of the air spring shock absorber assembly.
Alternatively, the spring tray 2 is welded to the shock absorber fluid reservoir 1. By adopting the welding to connect the spring tray 2 and the shock absorber liquid storage cylinder 1, the structure is stable, and the gap between the spring tray 2 and the shock absorber liquid storage cylinder 1 can be sealed. It can be understood that the spring tray 2 is provided with a through hole along the axial direction thereof, and the shock absorber liquid storage cylinder 1 is arranged in the through hole in a penetrating way.
As shown in fig. 1, the small diameter end of the spring tray 2 is located inside the air spring piston 4, and an annular seal ring 6 is disposed at an axial end face of the small diameter end of the spring tray 2. So set up, it can be understood that when installing air spring piston 4, air spring piston 4 removes to the direction that is close to the big footpath end of spring tray 2, can drive ring seal 6 and support and press on spring tray 2, guarantees the leakproofness between air spring piston 4 and the shock absorber liquid receiver 1.
As shown in fig. 1 and 2, the spring tray 2 is provided with an annular groove 21 extending along the circumferential direction thereof, the bottom surface of the annular groove 21 forms a second conical surface 211, and the elastic washer 3 is disposed in the annular groove 21 and is pressed against the second conical surface 211. By arranging the annular groove 21, the elastic gasket 3 can be limited, and the elastic gasket 3 is prevented from sliding off the spring tray 2. The second conical surface 211 can enable the elastic washer 3 to be in a conical structure after being sleeved on the spring tray 2, so that the elastic washer 3 is in contact fit with the first conical surface 41 of the air spring piston 4, and the contact area is large, so that enough friction force between the air spring piston 4 and the elastic washer 3 is ensured.
Further, an annular clamping groove 22 communicated with the annular groove 21 is further formed in the spring tray 2, and the elastic washer 3 is partially clamped in the annular clamping groove 22. By arranging the annular clamping groove 22 and matching with the elastic gasket 3, the limit capability of the elastic gasket 3 is further improved.
Alternatively, referring to FIG. 2, the annular clamping groove 22 is relatively close to the small diameter end of the spring tray 2. It can be appreciated that when the air spring piston 4 is installed, the air spring piston 4 is sleeved on the spring tray 2 by the small diameter end of the spring tray 2, and the small diameter end, which is relatively close to the spring tray 2, of the annular clamping groove 22 can enhance the stability of the elastic gasket 3, so that the elastic gasket 3 is prevented from deforming under the thrust of the air spring piston 4 to move to the large diameter end of the spring tray 2.
Referring to fig. 1 and 2, the spring tray 2 has an annular catching protrusion 23 thereon. The air spring shock absorber assembly further comprises a dust cover 5 sleeved on the air spring piston 4, and the dust cover 5 is clamped to the annular clamping protrusion 23. By providing the annular clamping protrusion 23, the dust cover 5 is convenient to install.
As shown in fig. 1, the air spring damper assembly further includes an air spring bellows 7 and a protective sleeve 8, the air spring bellows 7 being connected to the air spring piston 4, the protective sleeve 8 being disposed around the air spring bellows 7 and outside the air spring bellows 7. The dust cap 5 is connected to the casing 8.
As shown in fig. 3, the diameter of the first tapered surface 41 gradually increases from inside to outside in the axial direction of the air spring piston 4. The first conical surface 41 is a wall surface of an opening at one end of the air spring piston 4, that is, the opening of the air spring piston 4 is a trumpet-shaped opening, so that the air spring piston 4 and the spring tray 2 are assembled conveniently.
Referring to fig. 3, the inner wall surface of the air spring piston 4 further includes an annular surface 42 connected to the first tapered surface 41, and the annular surface 42 is in contact with the annular seal ring 6. It can be appreciated that the annular sealing ring 6 is clamped between the annular surface 42 of the air spring piston 4 and the shock absorber liquid storage barrel 1, so that the contact area between the annular sealing ring 6 and the inner wall surface of the air spring piston 4 can be increased when the annular sealing ring 6 is pressed, thereby improving the sealing effect and increasing the friction force.

A vehicle comprising the air spring damper assembly of the above embodiment.
