Abstract

The invention discloses a function integrated air spring which comprises an upper cover plate, an air bag, an upper end plate and a lower end plate. An auxiliary spring is connected between the upperend plate and the lower end plate, the periphery of the upper cover plate is connected with the outer periphery of the upper end plate or the outer periphery of the auxiliary spring through the air bag, and a vertical oil pressure shock absorber mounting base, a transverse oil pressure shock absorber mounting base and a transverse rubber soft stop plate are integrally arranged on the peripheral edge of the upper cover plate; a plurality of mounting holes for fixing a vehicle body are further formed in the top surface of the upper cover plate. The air spring has the advantages that the rigidityis adjustable, the application range is wide, and the overall structure and layout are optimized.

Description

technical field [0001] The invention mainly relates to buffering and damping technology, in particular to a function-integrated air spring. Background technique [0002] As an important secondary suspension component of rail transit vehicles, air springs have the functions of carrying the weight of the car body and passengers, satisfying the vehicle's operating characteristics and passenger comfort, maintaining the height of the car body floor surface, and providing vertical and horizontal deformation. . The traditional air spring has a single structure and function, and is generally only used as a secondary damping element. On some trains, especially new energy trains, due to the compact structure of the bogie, it is impossible to independently design the installation space for each steering component, so some functional components need to be integrated into the air spring. Since the multi-functional air spring integrates a variety of bogie functional parts, the stress si...
