Problems solved by technology

[0004] However, in the prior art, the bearing capacity of the diaphragm air spring used in the cab is relatively small, and the structure of the lower piston is mostly arc-shaped, which is not conducive to the control of the production process; and the volume occupied by the upper cover and the lower piston body is not fully utilized. , when the load is large, the air pressure inside the airbag is too high and the stiffness is too large, which is not conducive to improving the life of the air spring and improving the ride comfort

Abstract

The invention belongs to the technical field of diaphragm air springs, and in particular relates to a diaphragm air spring with an additional air chamber for a cab, which includes an upper cover, a rubber air bag and a lower piston sequentially connected from top to bottom. The periphery is equipped with an upper pressing device for sealing the upper cover tightly, and the periphery of the lower piston is provided with a lower pressing device for sealing the lower piston tightly. The interior of the aluminum upper cover is an inner hollow structure. The inner cavity of the lower piston is also provided with a hollow structure as an additional air chamber. The diaphragm air spring has a simple structure, can effectively reduce the stiffness of the air spring, has an obvious weight reduction effect, can reduce the unsprung mass, and improves the ride comfort of the vehicle.

Description

technical field [0001] The invention belongs to the technical field of air springs, in particular to a membrane-type air spring for a driver's cab with an additional air chamber. Background technique [0002] Air spring is an important component of air suspension. It is widely used in many fields such as commercial vehicle cab, train, automobile, and precision equipment shock absorption. As an ideal elastic element, air spring has nonlinear characteristics and can provide good support for vehicles. ride comfort. [0003] Air springs can be generally divided into bladder air springs, membrane air springs and composite air springs. Due to its compact structure, diaphragm air springs are often used in occasions where the space is relatively compact, such as cab suspension. [0004] However, in the prior art, the bearing capacity of the diaphragm air spring used in the cab is relatively small, and the structure of the lower piston is mostly arc-shaped, which is not conducive t...
