Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a split-type top mount assembly. Background Technology

[0002] As an important vibration damping component, air springs primarily function to effectively reduce vibrations during vehicle operation, thereby significantly improving ride comfort. There are two main types of air springs used in vehicles: those with built-in solenoid valve dampers and those with external solenoid valve dampers. Air springs with external solenoid valve dampers are equipped with end caps, and the current sealing method involves setting a sealing structure between the end cap and the top seat of the air spring to achieve a seal.

[0003] However, this traditional structure has obvious defects. Due to its unreasonable structural design, the overall structure is not compact enough, resulting in poor sealing. During vehicle operation, if the sealing performance is poor, the gas inside the air spring is prone to leakage, which may affect the overall performance and safety of the vehicle. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a split-type upper support assembly, the specific technical solution of which is as follows:

[0005] A split-type top seat assembly includes a top seat body and an end cap body. The bottom outer side of the end cap body has a second annular sealing ring, and the top outer side wall of the top seat body has a first annular sealing ring adapted to the second annular sealing ring. The top of the end cap body has an annular sealing frame. When the bottom side of the end cap body is inserted into and contacts the top side of the top seat body, the outer side of the second annular sealing ring and the inner side of the first annular sealing ring are in close contact, and at the same time, the bottom side of the annular sealing frame abuts against the top sides of the first and second annular sealing rings.

[0006] Preferably, the top side of the top seat body and the inner side of the first annular sealing ring are provided with an annular fixing groove, and the bottom of the end cover body has a fixing block that matches the annular fixing groove. When the end cover body is inserted into the top seat body, the fixing block is simultaneously inserted into the annular fixing groove.

[0007] Preferably, the annular sealing frame has multiple guide holes evenly arranged along the axial direction inside, and a locking rod is inserted into the guide holes. One end of the locking rod located inside the annular sealing frame has a pull block. A spring is provided between the annular sealing frame and the pull block, which is sleeved on the outer surface of the locking rod. One end of the spring is connected to the inner side of the annular sealing frame, and the other end of the spring is fixedly connected to the pull block. The inner wall of the top seat body has a slot adapted to the locking rod. When the end cap body is inserted into the inner side of the top seat body, one end of the locking rod can be inserted into the slot.

[0008] Preferably, the bottom of the end cap body has a limiting post on the side near the pull block, and the pull block is connected to a pull ring adapted to the limiting post by a rope. When one end of the locking rod is pulled away from the locking groove, the pull ring can be hooked into the limiting post.

[0009] The beneficial effects of this utility model are:

[0010] 1. Through the dual sealing design of the first and second annular sealing rings, as well as the auxiliary sealing effects of the fixing block and the annular fixing groove, and the clamp rod and the groove, the split top seat assembly can effectively prevent gas leakage inside the air spring, ensuring that the air spring always maintains good vibration damping performance and providing strong protection for the smooth driving of the vehicle.

[0011] 2. Through the multiple cooperation structure of the annular fixing groove and fixing block, and the clamping rod and the clamping groove, the connection stability between the top seat body and the end cover body is enhanced from multiple dimensions. This stable connection can withstand various complex external forces during vehicle operation, ensuring the structural integrity and stability of the air spring system.

[0012] 3. The design of the pull ring and limiting post makes the disassembly, installation, and maintenance of the split-type top mount assembly simple and easy. Operators can easily complete the relevant operations without the need for complicated tools and cumbersome procedures, greatly saving time and labor costs and improving work efficiency.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] Example

[0018] Please refer to Figures 1-2The split-type top seat assembly provided by this utility model mainly consists of a top seat body 1, an end cap body 2, an annular sealing frame 3, a locking rod 4, a spring 5, a pull block 6, a pull ring 7, a limiting post 8, a first annular sealing ring 9, and a second annular sealing ring. These components work together to achieve the goals of improving the sealing performance, connection stability, and ease of operation of the air spring 5.

[0019] Specifically, a first annular sealing ring 9 is arranged around the top outer wall of the top seat body 1, and a second annular sealing ring is correspondingly arranged on the bottom outer side of the end cap body 2. The size and shape of these two annular sealing rings are mutually compatible. When the bottom side of the end cap body 2 is inserted into and in close contact with the top side of the top seat body 1, the outer side of the second annular sealing ring will tightly abut against the inner side of the first annular sealing ring 9. This tight fit forms an effective sealing barrier between the two, effectively preventing gas inside the air spring 5 from leaking from the connection between the top seat body 1 and the end cap body 2, significantly improving the sealing performance of the air spring 5.

[0020] Specifically, an annular fixing groove 100 is provided on the top side of the top seat body 1, inside the first annular sealing ring 9. The bottom of the end cap body 2 has a fixing block 21 that matches the annular fixing groove 100. During assembly, as the end cap body 2 is inserted into the top seat body 1, the fixing block 21 accurately inserts into the annular fixing groove 100. This structural fit not only provides initial positioning and connection for the top seat body 1 and the end cap body 2, but also further enhances the stability of the connection between them. Simultaneously, the tight fit between the fixing block 21 and the annular fixing groove 100 assists in sealing, effectively reducing the possibility of gas leakage.

[0021] Specifically, the annular sealing frame 3 is installed on the top of the end cap body 2, and multiple guide holes 30 are evenly distributed axially inside it. A locking rod 4 is inserted into each guide hole 30, and the locking rod 4 can slide freely within the guide hole 30. A pull block 6 is connected to one end of the locking rod 4 located inside the annular sealing frame 3, and a spring 5 is provided between the annular sealing frame 3 and the pull block 6. The spring 5 is sleeved on the outer surface of the locking rod 4, with one end firmly connected to the inner side of the annular sealing frame 3 and the other end tightly fixed to the pull block 6. A slot 101 adapted to the locking rod 4 is provided on the inner wall of the top seat body 1. The annular sealing frame 3 can effectively seal the sealing joint at the top of the first annular sealing ring 9 and the second annular sealing ring 10, further improving the sealing performance of this application.

[0022] When the end cap body 2 is inserted into the inner side of the top seat body 1, under the elastic force of the spring 5, the locking rod 4 will move along the guide hole 30 towards the locking groove 101, and finally one end of the locking rod 4 will be inserted into the locking groove 101. This structural design further strengthens the connection between the top seat body 1 and the end cap body 2. Even if the vehicle is subjected to strong vibration and impact during driving, the two can maintain a stable connection and will not easily loosen, thereby improving the reliability and safety of the entire air spring 5 system.

[0023] Specifically, a limiting post 8 is provided on the bottom side of the end cap body 2 near the pull block 6, and a pull ring 7 is connected to the pull block 6 by a high-strength rope. When it is necessary to disassemble, adjust, or maintain the split-type top seat assembly, the operator can pull the pull ring 7 to move the pull block 6. The movement of the pull block 6 will cause the locking rod 4 to overcome the elastic force of the spring 5 and move away from the locking groove 101. When one end of the locking rod 4 is completely disengaged from the locking groove 101, the pull ring 7 can be hooked into the limiting post 8. At this time, the locking rod 4 will be limited to the position where it is disengaged from the locking groove 101, which facilitates the operator's subsequent operations and effectively improves the convenience and efficiency of operation.

[0024] Working principle: When the air spring 5 is working normally, the top seat body 1 and the end cover body 2 are tightly fitted together through a series of sealing and connecting structures. The first annular sealing ring 9 and the second annular sealing ring work together to form a strong sealing pressure on their contact surface, effectively preventing gas leakage inside the air spring 5. At the same time, the cooperation between the annular fixing groove 100 and the fixing block 21, and the cooperation between the locking rod 4 and the locking groove 101, ensure that the top seat body 1 and the end cover body 2 will not undergo relative displacement when subjected to external forces, maintaining the stability of the air spring 5 structure.

[0025] When maintenance or repair of the air spring 5 is required, the connection between the locking rod 4 and the locking groove 101 can be easily released by pulling the pull ring 7 and hanging it on the limiting post 8. This makes it easier to separate the end cover body 2 from the top seat body 1, greatly improving the efficiency of maintenance and repair of the air spring 5 and reducing maintenance costs.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
