Abstract
The utility model relates to a side bearing structure for a joint bogie of a railway wagon, which comprises four elastic side bearings arranged on the joint bogie and is characterized in that the four elastic side bearings are annularly arranged on the structure of the bogie by taking the center of the bogie as the center of a circle; the elastic bearings arranged on the front and rear wagons are symmetrical about the transverse center line of the bogie; and elastic side bearing rollers distributed in the circumferential direction on the pitch circle of the same wagon of the four elastic bearings are respectively close to one end of the longitudinal center line of the bogie. The side bearing structure can ensure the longitudinal stiffness of the elastic side bearings to be fully utilized.
Description
Technical field
The utility model relates to a kind of railway truck articulated truck side bearing structure.
Background technology
The automobile-used joint bogie truck in joint need support former and later two car bodies, so the joint bogie truck needs four side bearings.The arrangement form of present elastic side bearing is the symmetrical structure (as shown in Figure 1) that side bearing is parallel to the longitudinal direction of car center.Owing on horizontal and vertical, produce displacement with respect to body side bearing at little curve place bottom side bearing 11 during vehicle operating, and the width that the body side bearing wearing plate needs is bigger, the longitudinal rigidity of side bearing can not all play effect when this kind side bearing structure just can cause vehicle operating, the stability when having reduced the vehicle high-speed cruising.
Summary of the invention
At the problems referred to above, main purpose of the present utility model is to provide a kind of railway truck articulated truck side bearing structure, and it can guarantee the high stability of vehicle.
For achieving the above object, a kind of railway truck articulated truck side bearing structure provided by the utility model, it comprises four elastic side bearings that are arranged on the joint bogie truck, it is characterized in that: four described elastic side bearings are the center of circle with the center of described bogie truck, annular is arranged on the framework of described bogie truck, the described elastic side bearing of vehicle is with the cross central line symmetry of described bogie truck before and after being positioned at, and four described elastic side bearings circumferencial direction on pitch circle is arranged with the elastic side bearing roller of car all near an end of described bogie truck longitudinal centerline.
Adopt technique scheme, the utility model changes original side bearing layout, makes the longitudinal rigidity of elastic side bearing to make full use of.

The specific embodiment
In order to describe structure of the present utility model, characteristics and effect in detail, existing following preferred embodiment of act and conjunction with figs. are described as follows.
As shown in Figure 2, be a kind of railway truck articulated truck side bearing structure provided by the utility model, it comprises four elastic side bearings 1 that are arranged on the joint bogie truck equally, four elastic side bearings 1 are the center of circle with the center of bogie truck 2, annular is arranged on the framework 3 of bogie truck 2, before and after the elastic side bearing 1 of vehicle be cross central line symmetry with bogie truck 2, and four elastic side bearings 1 on pitch circle the circumferencial direction arrangement with the elastic side bearing roller 4 of bogie truck all near an end of bogie truck longitudinal centerline.
Adopt said structure, the utility model has changed original elastic side bearing layout, makes the longitudinal rigidity of elastic side bearing to be fully used.
