Air spring structure provided with auxiliary air chamber

Abstract

The invention belongs to the technical field of air spring products, and particularly discloses an air spring structure provided with an auxiliary air chamber. The air spring structure comprises an upper cover, a flanging upper compression ring, a rubber air bag body, a lower compression ring and a piston which are sequentially connected according to the order of sequence, an opening part at the upper end of the rubber air bag body is installed on the upper cover through the flanging upper compression ring, an oblique bulge is arranged on the upper cover, and an opening part at the lower end of the rubber air bag body is installed on the piston through the lower compression ring; and a piston cover is further arranged at the top of the piston, a buffer block is installed on the piston cover in a matched mode, an orifice is formed in the buffer block, and the buffer block divides a cavity formed by the rubber air bag body and the piston into a main air chamber of the interior of the rubber air bag body and the auxiliary air chamber of an inner cavity of the piston. According to the air spring structure, the damping effect of driving cabs of trucks, especially medium-sized trucks orheavy-type trucks with the load capacity being large can be effectively improved, a failure protection mechanism is designed, the safety and the comfort of the air spring structure are greatly improved, and the requirement of a market for light weight is met.

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...
