Abstract
The utility model relates to a side-bearing structure directly controlling 4 steering bogie on the body frame. A body frame is composed of a left side beam, a right side beam, a front side beam, a rear side beam, a central longitudinal beam, a front beam positioned behind the front side beam and a rear beam before the rear side beam. Two steering bogies are provided on the front side beam and the rear side beam respectively. The body frame is provided with 2 front beams and 2 rear beams. The underside of the central beam is respectively connected a small longitudinal beam at the location equidistant to the front beam and at a location equidistant to the rear beam. Each small longitudinal beam is connected with 2 steering bogies at two sides. Each steering bogie is provided with 2 lower side-bearing structures at the left and right upper surfaces. Each beam bottom of the body frame is provided with an upper side-bearing structure matched to the upper side-bearing structure. The utility model provides 8 side-bearing structures on the body frame. 8-side-bearing structures directly act on the lower side-bearing structures on the steering bogies, changing 2 side-bearing systems into one system and reducing the freedom degree by half. The vehicle body ability to control the hunting motion of the steering bogie is increased, hereby increasing the dynamical performance and speed for the vehicle and greatly simplifying the vehicle structure.
Description
Technical field
The utility model relates to the railway vehicle of growing up, especially the side bearing structure of the railway vehicle of eight four bogie trucks.
Background technology
At present, eight four bogie truck railway vehicles all adopt the car body side bearing structure of four bogie trucks of control indirectly, that is: the car body great underframe is controlled the side bearing of two little underframe, and two handle frame side bearings go to control four bogie truck side bearings again.
As shown in Figure 1 to Figure 3: in eight four bogie truck railway vehicles, body side bearing 4 on the car body great underframe 1 and bottom side bearing 3 mutual actions on the handle frame 2, car body great underframe 1 control handle frame 2.Body side bearing 5 on the handle frame 2 and bottom side bearing 6 mutual actions on the bogie truck 7, handle frame 2 control bogie trucks 7.Be that car body great underframe 1 is that bogie truck 7 is controlled in series connection for 6 liang by bottom side bearing 3 and body side bearing 4, body side bearing 5 and bottom side bearing.
This two-stage side bearing system causes the car body great underframe to control the bogie truck side bearing indirectly, make that the degree of freedom between car body great underframe and the bogie truck is excessively big, cause car body great underframe control bogie truck hunting scarce capacity, the vehicle dynamics performance descends, running velocity is not high, and the vehicle structure complexity.
Summary of the invention
In view of above-mentioned, the purpose of this utility model is the side bearing structure that proposes four bogie trucks of a kind of car body great underframe direct control, and it can improve and improve the grow up dynamic performance of railway vehicle of eight four bogie trucks, improves running velocity, simplifies vehicle structure.
For this reason, the utility model is by the following technical solutions:
The side bearing structure of four bogie trucks of a kind of car body great underframe direct control, it has a car body great underframe, respectively there are two bogie trucks the below, front and back end of car body great underframe, the car body great underframe be by left and right sides curb girder, front and back end carriage, center stringer, be positioned at before the end carriage rear front cross rail, be positioned at the frame body that the after cross member in end carriage the place ahead, back constitutes, it is characterized in that: described car body great underframe is provided with two front cross rails and two after cross members; On the bottom surface of described center stringer, respectively be connected a stringer with distance two after cross member equidistant apart from two front cross rail equidistant; The two ends of each stringer respectively connect a described bogie truck; The upper surface of the left and right sides of each bogie truck is set side bearing; The bottom surface of each crossbeam of described car body great underframe is provided with the body side bearing that matches with the bottom side bearing of described bogie truck.
The center stringer of described car body great underframe and described stringer flexibly connect.
Described stringer and described bogie truck flexibly connect.
Vehicle load passes to stringer (carrier bar) by great underframe, passes to bogie truck by stringer again.
The utility model has the advantages that: the little underframe in original scheme is become carrier bar, cancel all side bearings on it, eight body side bearings are set on great underframe, corresponding with the bottom side bearing on four bogie trucks.Body side bearing on the great underframe is without carrier bar, directly and the bottom side bearing mutual action on the bogie truck, thereby is to become one to be with the side bearing system by two, degree of freedom reduces half, car body control bogie truck hunting ability strengthens, thereby improved vehicle dynamics performance and running velocity, and vehicle structure is simple greatly.

The specific embodiment
See also Fig. 4-Fig. 6.The utility model relates to the side bearing structure of four bogie trucks of a kind of car body great underframe direct control, and it has a car body great underframe 11, and respectively there are two bogie trucks 17 below, front and back end of car body great underframe 11.Wherein:
Car body great underframe 11 be by left and right sides curb girder 12, front and back end carriage 13, center stringer 14, be positioned at before the end carriage rear two front cross rails 15, be positioned at two frame bodies that after cross member 16 constitutes in end carriage the place ahead, back.
On the bottom surface of center stringer 14, respectively be connected a stringer 18 with distance two after cross members 16 equidistant apart from two front cross rails, 15 equidistant.
The rear and front end of each stringer 18 respectively connects a bogie truck 17;
The upper surface of the left and right sides of each bogie truck 17 is set side bearing 19;
The bottom surface of each crossbeam of car body great underframe 11 is provided with the last paraxonic 20 that matches with the following paraxonic 19 of bogie truck 17.
Adopt body center plate 30, truck center plate 31 to flexibly connect between the center stringer 14 of car body great underframe 11 and the stringer 18, body center plate 30 is fixed on the car body great underframe 11, truck center plate 31 is fixed on the stringer 18, adopts the structure of upper and lower cartridge can make between center stringer 14 and the stringer 18 and relatively rotates.
