Auxiliary bearing saddle assembly for spherical cap of pendulum goods train

A technology for railway freight cars and bearing saddles, which is applied in the direction of the device for lateral relative movement between the underframe and the bogie, and can solve the problem of ensuring the swing function of the side frame of the bogie of the tilting train, reducing the life of the bearing saddle and bearings, and wire transmission. It can reduce the probability of jamming, long fatigue life, and evenly loaded bearings.

Embodiment 1

[0026] figure 1 It is shown that the first specific embodiment of the present invention is: a spherical crown auxiliary saddle assembly for a pendulum railway freight car, which includes the swing seat 2 in the guide basket 1a of the side frame 1 and the load saddle below the swing seat 2 4. The lower part of the bearing saddle 4 is in contact with the outer ring of the bearing 5 . Both ends of the upper surface of the rocking seat 2 are inlaid on both sides of the upper part of the guide basket 1a of the side frame 1, the lower surface of the rocking seat 2 is a concave spherical surface, and the concave spherical surface is matched with the convex spherical crown 3, and the lower part of the convex spherical crown 3 is in contact with the bearing. The saddle 4 is connected.

[0027] figure 1 and Figure 5a, Figure 5b, Figure 5c It shows that the working process and mechanical principle of this example are: the rocking seat 2 transmits the force from the side frame 1 to ...

Embodiment 2

[0032] image 3 It shows that the structure of this example is basically the same as that of Example 1, the only difference is that the lower part of the convex spherical crown 3 is connected to the saddle 4 in a specific way: a layer of elastic material is sandwiched between the upper and lower liners 8 and 10 9. The elastic material 9 can generally be rubber or elastic plastic. The lower part of the convex spherical crown 3 and the upper liner 8 are matched by a circular inlay pair with fretting gaps. Generally, a circular protrusion and a concave connection pair can be used to cooperate, which can make it more convenient and simple to install. The inlaid lower liner 10 is inlaid and fastened or clamped on the upper part of the bearing saddle 4 .

Abstract

The invention discloses a spherical crown pair adapter component used for a pendulum railway freight car, which comprises a shaking seat (2) inside of the guide basket (1a) of a side frame (1) and an adapter (4) under the shaking seat (2), wherein, the lower part of the adapter (4) is matched with the outer ring of a bearing (5). The spherical crown pair adapter component is characterized in that the two ends of the upper surface of the shaking seat (2) are embedded on the two edges at the upper part of the guide basket (1a) of the side frame (1), the lower surface of the shaking seat (2) is a concave spherical surface, the concave spherical surface is matched with a convex spherical crown (3), and the lower part of the convex spherical crown (3) is connected with the adapter (4). The invention has the advantages that surface force transmission is adopted, the crown pair adapter component is free from unbalanced or inclined loadings, the adapter and the convex spherical crown (3) are under even load, the fatigue life is long, the back swing resistance of the side frame is small, and the work is reliable.

Description

technical field [0001] The invention relates to a spherical crown auxiliary saddle assembly for a pendulous railway freight car. Background technique [0002] There are two side frames in the freight train bogie, and the front and rear ends of one side frame are respectively equipped with load-bearing saddle assemblies, which are connected with the bearings of the wheel shaft through the load-bearing saddle assemblies. Bearing force transmission components. Image 6 It is an exploded view of an existing pendulum truck bearing saddle assembly. Such as Image 6 As shown, the structure of the bearing saddle assembly of the existing pendulum railway freight car is: the upper part of the rocking seat 2' is fixed in the guide basket 1a of the side frame 1, and the bearing saddle 4' is placed in the guide basket of the side frame 1 below the rocking seat 2' 1a, and the concave arc surface on the upper part of the bearing saddle 4' is movably matched with the convex arc surface on ...
