Abstract
The invention discloses a frame of bogie for an A-type broad-gauge metro vehicle. The frame comprises side beams, a cross beam and a primary spring seat. The frame is characterized in that the cross beam and the side beams of the frame are in transition connection through a connecting seat for the cross beam and side beams, and the connecting seat for the cross beam and side beams and a brake cylinder mounting seat are integrated to a whole body, an air spring assisted air cylinder on the vehicle is taken as an auxiliary chamber of the air spring. According to the frame, the side beams and the cross beam of the frame are in transition connection through the connecting seat for the cross beam and side beams, so that the adverse effect on the side beams is avoided when a steel pipe penetrates through the side beams, and furthermore, welding lines are removed from a high stress area, so that the stress condition of the frame is improved and the service life of the frame is prolonged; the air spring assisted air cylinder on the vehicle replaces the auxiliary chamber of the air spring in the side beams and the cross beam, so that the technological requirements for welding of the cross beam and the side beams are reduced; through the integrated brake cylinder mounting seat and the connecting seat for the cross beam and side beams, the number of the welding lines at the place is greatly reduced and the welding technology is improved.
Description
Technical field
The present invention relates to guideway vehicle and manufacture and design field, especially relate to a kind of railcar truck frame of 1600mm gauge circuit.
Background technology
The gauge of current domestic railcar circulation line is commonly 1435mm, and the design of bogie truck and framework all puts before this to be carried out.The circuit of 1600mm gauge adopts without any metro operation company, and corresponding bogie truck and frame design are also in blank always.The welded frame that domestic railcar adopts, horizontal curb girder junction many employings connected structure, causes high stress areas to be just in time in position while welding, greatly reduces the fatigue life of framework; Crossbeam steel pipe and curb girder casing through, be commonly used for the auxiliary chamber of air bellow, this is high to welding requirements, technique realize difficulty.Brake cylinder mount pad and horizontal curb girder interface mostly are separate structure in addition, and make framework structure complicated, weld seam is various and not accessible, and welding quality is restive.
Summary of the invention
The object of this invention is to provide a kind of framework on 1600mm gauge railcar Multiple disc brake bogie truck of brand-new exploitation, improve the force-bearing situation of framework, improve the fatigue life of framework; Reduce the manufacturability requirement of horizontal side beam welding; Reduce the quantity of weld seam, improve welding usability.
For achieving the above object, the invention provides a kind of A molded breadth rail subway vehicle steering rack framework, comprise curb girder, crossbeam, primary spring seat, it is characterized in that: connected by horizontal side beam connecting seat transition between the horizontal curb girder of framework, and horizontal side beam connecting seat and brake cylinder mount pad integrate, adopt and be positioned at the auxiliary chamber of the air bellow supplementary reservoir on car as air bellow.
Connected by horizontal side beam connecting seat transition between the horizontal curb girder of framework of the present invention, avoid steel pipe and run through the adverse effect that curb girder produces curb girder, weld seam is removed from area of high stress, improves the force-bearing situation of framework, the fatigue life of raising framework; Replace with the air bellow supplementary reservoir be positioned on car the auxiliary chamber being positioned at the air bellow of curb girder and crossbeam, reduce the manufacturability requirement of horizontal side beam welding; By brake cylinder mount pad and the horizontal side beam connecting seat of integration, greatly reduce the quantity of weld seam herein, improve welding usability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
With reference to Fig. 1, be connected by the transition of horizontal side beam connecting seat 3 between truck transom 4 with curb girder 1, and horizontal side beam connecting seat 3 and brake cylinder mount pad 2 integrate, avoid steel pipe and run through the adverse effect that curb girder produces curb girder, weld seam is removed from area of high stress, decrease the quantity of weld seam herein, improve welding usability, 5 is primary spring seats, one system spring perch does not establish auxiliary chamber, adopt and be positioned at the auxiliary chamber of the air bellow supplementary reservoir on car as air bellow, reduce the manufacturability requirement of horizontal side beam welding.
