Embodiment Construction

[0067] Below, based on the attached Figure 1 to Figure 3 and Figure 5 to Figure 6 , embodiments of the air spring for a vehicle and the bogie according to the present invention will be described. figure 1 The illustrated air spring 1 for a vehicle is configured by combining an outer tube 2 , an inner tube 3 , a diaphragm 4 , an outer stopper 5 , an inner stopper 6 , and a pressing plate 7 .

[0068] The outer cylinder 2 is a member in which a support shaft 2c having an air port 2b for air supply and exhaust is provided at the center of an upper panel 2a covering an upper portion of the diaphragm 4 , and the outer cylinder 2 is attached to a vehicle body 20 .

[0069] A diaphragm 4 is disposed between the outer cylinder 2 and the inner cylinder 3 . Compressed air is introduced into the inside of the diaphragm 4 so that an air cushioning effect can be exhibited during inflation.

[0070] The outer stopper member 5 is a compression-type cushioning material that undergoes co...

Abstract

The present invention addresses the problem of further reducing the overall height and at the same time ensuring preferable spring property at the time of deflation in an air spring for a vehicle using both an external stopper and an internal stopper each having spring property. Disclosed is an air spring for a vehicle, wherein an internal stopper (6) is provided inside a diaphragm (4) and a concave portion (8) formed on an inner tube (3) is placed inside an external stopper (5) to overlap the external stopper (5) in the height direction by the length (L). In an embodiment, the concave portion (8) is provided with an inverted conical peripheral wall (8-1) and a bottom wall (8-2), a pressing plate (7) is provided with an inverted conical load application surface (9a) in a vertically suspended manner, an inverted conical semi-shear stopper is provided as the internal stopper (6), and an inside diameter surface (fi) and an outside diameter surface (fo) of the semi-shear internal stopper (6) are fixed on the load application surface (9a) and on an inner surface of the peripheral wall (8-1), respectively.

Description

technical field [0001] The present invention relates to an air spring for a vehicle and a bogie using the air spring for a vehicle, in particular to an air spring with excellent spring characteristics when inflated (normally filled with air) and deflated (so-called burst) and is compatible with the existing There are air springs that can achieve further miniaturization than other products. Background technique [0002] An air spring used as a suspension for a railway vehicle is provided as an auxiliary spring between a bogie and a vehicle body of the vehicle. The air springs are divided into those for bogies with bolsters and those for bogies without bolsters. [0003] Among the air springs described above, there is an air spring disclosed in Patent Document 1 below. The air spring of Patent Document 1 has: an inner cylinder mounted on the bogie side; an outer cylinder mounted on the vehicle body side; and a diaphragm disposed between the inner cylinder and the outer cylin...
