Embodiment Construction

[0040] Such as figure 1 As shown, an air spring structure with an additional air chamber according to the present invention includes an upper cover 2, a flanged upper pressure ring 3, a rubber airbag body 4, a lower pressure ring 7, and a piston 8 connected in sequence. The upper opening of the rubber airbag body 4 is installed on the upper cover 2 through the flanged upper pressure ring 3 , and the top of the upper cover 2 is also provided with an air nozzle 1 . The lower end opening of the rubber air bag body 4 is installed on the piston 8 by the pressing ring 7, and the top of the piston 8 is also provided with a piston cover 6 (such as Figure 10 shown), the piston cover 6 is equipped with a buffer block 5, and the buffer block 5 separates the cavity formed by the rubber air bag body 4 and the piston 8 into the main air chamber 1 in the air bag and the additional part of the piston 5 inner chamber. As for the air chamber II, the volume ratio of the main air chamber I to t...

Abstract

The invention belongs to the technical field of air spring products, and specifically discloses an air spring structure with an additional air chamber, including an upper cover, a flanged upper pressure ring, a rubber air bag body, a lower pressure ring, and a piston connected in sequence, and the rubber The upper opening of the airbag body is installed on the upper cover through the flange upper pressure ring, and the upper cover is provided with an inclined protrusion, and the lower opening of the rubber airbag body is installed on the piston through the lower pressure ring, and the piston The top is also provided with a piston cover, and a buffer block is installed on the piston cover, and the buffer block is provided with an orifice, and the buffer block separates the cavity formed by the rubber air bag body and the piston into the main cavity in the rubber air bag. Additional air chamber for air chamber and piston chamber. The air spring can effectively improve the shock absorption effect of trucks, especially medium-sized trucks or heavy-duty truck cabs with a large load, and is designed with a failure protection mechanism to greatly improve its safety and comfort and meet the market's lightweight needs.

Description

technical field [0001] The invention belongs to the technical field of air spring products, in particular to an air spring structure with an additional air chamber. Background technique [0002] In the prior art, an air spring is a key element in an air suspension system, and its dynamic characteristics play a central role in the comfort and safety of the suspension system. The air spring without an additional air chamber does not contain an orifice and an additional air chamber, so it cannot absorb energy through air damping, thereby dampening vibrations, and it does not have the function of adjusting the stiffness itself. The introduction of throttle holes and additional air chambers to the air spring can make up for the above shortcomings. The throttle holes are used to connect the main air chamber and the additional air chamber to achieve gas exchange, thereby absorbing energy and damping vibration. The volume of the additional air chamber Mainly affects the range of ad...
