Air spring for vehicle and hanger mounting method thereof

Abstract

The invention provides an improved air spring for a vehicle. The air spring can be provided with a hanger convenient for carrying, meanwhile does not produce the butting problem of an upper supporting part and a lower supporting part caused by a hanging structure thereof, is suitable for hanging movement and is favorable for the durability of a stop dog. A rubber diaphragm (3) is arranged in the air spring for the vehicle in a mode of crossing the upper supporting part (1) on the vehicle body side and the lower supporting part (2) arranged on the chassis side below the upper supporting part (1), the upper supporting part (1) and the lower supporting part (2) are provided with female threads (16, 17) with a common longitudinal axis (P) respectively, and the female thread (17) of the lower supporting part (2) is constructed to screw with a lower male thread (22) formed at the lower end of the roughly bar-shaped hanger (B) for hanging the air spring. The female thread (16) of the upper supporting part (1) is constructed to screw with an upper male thread (21) positioned in the hanger (B) and spaced from the lower male thread (22) on the upper part, and meanwhile, the female thread (16) of the upper supporting part (1) is set in a state that the lower male thread (22) can pass.

Description

technical field [0001] The present invention relates to an air spring for a vehicle and a method for installing the suspension thereof. An air spring for a vehicle formed by making a diaphragm from a material, and a hanger installation method for the air spring for a vehicle. Background technique [0002] Currently, such air springs for vehicles such as Figure 4 As shown, there is a case in which an air spring A for a railway vehicle having a stopper s of a laminated rubber structure at the lower portion of the lower support portion 2 is transported. That is, use the rod-shaped hanger B with the ring part 23 that can hook the crane hook (not shown) at the upper end and the male thread 22 at the lower end. In the hanger B, the male thread 22 at the lower end is screwed with the female thread 17 formed at the center of the bead seat 5 serving as the lower support portion 2 of the air spring A. As shown in FIG. Thus, a state is formed in which the air spring A is suspended b...

AI Technical Summary

Problems solved by technology

As a result, there is a problem that, during a small number of vehicle movements in an air-leakage or air-free state, contact and friction between the temporarily used slide plate and the slide plate to be used also occur in unexpected suspension movements.

In addition, when transported by rail wagons or trucks with the spreader attached, the sliding plate and the sliding plate are rubbed against each other for a long time, and as a product, there may be a problem that it is worn out before use.
