Abstract

The invention discloses a cord thread integral winding reinforced rubber air spring. The cord thread integral winding reinforced rubber air spring comprises upper and lower flanges, and a bag body integrally vulcanized with upper and lower pressing rings; the upper flange is connected with an upper cover plate by an upper fastening piece; the lower flange is connected with a lower cover plate by alower fastening piece; the upper and lower pressing rings are arranged between the bag body and the upper and lower cover plates; a constraint flange connected with the upper cover plate sleeves thebag body; the bag body consists of an inner rubber layer, a skeleton layer and an outer rubber layer; the inner rubber layer is integrally vulcanized with the upper and lower flanges; the outer rubberlayer is integrally vulcanized with the upper and lower pressing rings; and cord threads in the skeleton layer perform the cross netty winding on the inner rubber layer and the upper and lower flanges to form a net-structured cord thread layer capable of integrally bonding the upper and lower flanges.

Description

technical field [0001] The invention relates to a vibration isolation element, in particular to a cord integrated winding reinforced rubber air spring. Background technique [0002] Air spring is a damping element with nonlinear static and dynamic stiffness. It can use the nonlinear stiffness and damping characteristics of air compression to isolate vibration and shock. It has been widely used in various power, machinery, precision instruments and other devices. vibration isolation or actuation design. [0003] The bearing capacity of the air spring depends on the gas pressure in the bag. For applications with small installation space, it is necessary to greatly increase the working pressure in the bag and reduce the size of the air spring to meet the installation space requirements. The substantial increase in the working pressure in the bladder puts forward higher requirements for the strength and airtightness of its joints. The traditional air spring capsule and cover p...
