An embodiment of the invention provides a bladder-type air spring, and relates to the technical field of air springs, aiming to solve the problems of misalignment between upper covers and bases of bladder-type air springs and excessive distortion of bladders during charging and discharging. The bladder-type air spring comprises a base, a bladder, an upper cover and a support body; the support bodyis located in an air chamber, is fixedly connected with the base, and is provided with a support surface disposed towards the upper cover; the support body is provided with a cavity and a throttlinghole; the cavity is communicated with the air chamber through the throttling hole; the base is provided with an air hole, one end of the air hole is communicated with the cavity, and the other end ofthe air hole penetrates to the outer wall of the base. The bladder-type air spring provided by the embodiment of the invention has the advantages that the support body is arranged between the upper cover and the base, the minimum distance between the upper cover and the base can be restricted under the action of the support body, and the anti-seismic property of the bladder-type air spring can beimproved through the throttling hole and the cavity.
Description
technical field [0001] The invention relates to the technical field of air springs, in particular to a bladder type air spring. Background technique [0002] According to the type of structure, air springs are mainly divided into three types: capsule type, membrane type and composite type; among them, capsule type air springs have been widely used in various equipment and structures (such as suspensions) to provide a certain shock absorption effect, among which , in practical applications, two-curve and three-curve types are the most common. [0003] None of the bladder air springs in the prior art has an additional air chamber, resulting in a high natural frequency of the bladder air spring as a whole, and the frequency cannot be adjusted; in addition, the bladder air spring does not have a supporting structure, resulting in In the end, it often leads to misalignment between the upper cover and the base, distortion and offset. [0004] To sum up, there are still many impr...
