Description
Technical Field
The invention belongs to the field of railway vehicle bogie devices, and particularly relates to an axle box external subway bogie with an integrated swing bolster and a lifting support device.
Background
The existing metro car bogie frame in China is generally integrally formed by casting, or a box-type cross beam and a box-type side beam are respectively welded by a plurality of plates, and then the box-type cross beam and the box-type side beam are welded together to form an integral box-type framework. The primary suspension system is based on a trapezoidal axle box assembly 4 as shown in fig. 1, wherein the trapezoidal axle box assembly 4 is located in an axle box mounting seat at the end of a frame side member 9, and the trapezoidal axle box assembly 4 is pivotally connected to an axle at the inner side of a wheel 10. However, the existing bogie has the following disadvantages or problems:
firstly, the manufacturability of the whole cast framework is poor, casting defects are large, the product quality is bad, the service life is influenced, when the box-type cross beam and the box-type side beam are assembled and welded with each other, the side beam upper cover plate and the cross beam upper cover plate need to be spliced and welded, and a motor hanging seat and a gear box hanging seat are further added to the two sides of the cross beam through a welding process, so that the number of the whole welding seams of the framework is large, the welding workload is large, the welding deformation of the framework is easy to cause, the residual welding stress is high, and the problems of high local position stress of the framework and low fatigue strength allowance.
Secondly, a primary suspension system based on the trapezoidal axle box device 4 and with the wheels 10 located on the outer side of the frame side beams 9 has the risk that the stability of the vehicle is poor, the operating speed of the vehicle cannot be too high, and the exposed wheels 10 are easily damaged. And the top of the side bearing on the existing bogie is a smooth plane, and when the side bearing plays a supporting role, dust and friction particles easily enter gaps, so that the side bearing is remarkably rubbed in the vibration and swing process of the advancing railway wheels, scratches and serious abrasion are generated, and the service life of the side bearing is greatly reduced.
In addition, the existing bogie has single function, and secondary damping parts such as an auxiliary traction pull rod, a vertical damper, a transverse damper, an anti-rolling torsion bar and the like of the existing bogie do not pass through a swing bolster and are directly connected to the bottom of the bogie body from a framework. In addition, the existing bolster structure does not have independent support and height adjustment mechanisms after the air springs are emptied, so that after the wheel of the bolster is turned, the floor of the carriage is lowered along with the bolster, but the height adjustment cushion cannot be directly added between the air springs and the bolster, but the carriage must be lifted and removed, and the bolster is also lifted and suspended, so that the height adjustment cushion can be added between the air springs and the bolster. This results in time and labor consuming, difficult, heavy, and extremely inefficient processes for adding the adjustment pad.
Disclosure of Invention
The invention provides an axle box external subway bogie with an integrated swing bolster and a lifting support device, and aims to solve the problems that the existing bogie has large integral welding seams of a framework, the framework is easy to deform in a welding mode or the stress of the local position of the framework is higher, the problem that a built-in axle box mode has the risks that the stability of a vehicle is poor, wheels are easy to be damaged, side bearings are easy to scratch and seriously abraded due to the fact that dust and friction particles easily enter side bearing gaps, and the technical problem that the process of adding a height adjusting pad between an air spring and the swing bolster wastes time and labor.
