A hanger is arranged below the horizontal frame and used for hanging a linear motor which is connected with two side beams of the framework by two transverse pulling rods. Middle parts of two side beams of the two T-shaped frames which are mutually hinged are connected with a central cross beam by rubber panel nodes. The central cross beam is connected with a traction cross beam of the upper part by longitudinal pulling rods on side parts, and central pins respectively penetrate the traction cross beam and the central cross beam to be connected into a whole structure. The traction cross beam is respectively connected with the side beams of the two T-shaped frames by an oil pressure damper, and the central cross beam is connected with the linear motor by the longitudinal traction pulling rods.

Technical Field

The invention relates to a bogie for a railway vehicle, and belongs to the field of mechanical manufacturing.

Background

At present, the rail vehicle bogie applied to railway trains, subways and light rail traffic generally adopts a rigid framework structure. Due to the influence and limitation of the wheel-rail line of the vehicle, when the wheel set runs to a curve with a relatively sharp bend angle, the part of the outer side of the rigid framework, which is close to the wheel set, can bear a relatively large torque action. Furthermore, the connection between the frame and the primary suspension device is subject to large impact forces at high vehicle speeds.

Therefore, the structure and the traction force transmission mode of the existing rigid framework are difficult to adapt to the use requirements of high-speed operation and complex working condition wheel-rail lines to a certain extent. Accordingly, the framework has higher design requirements on the manufacturing quality and material quality, thereby increasing the production difficulty and manufacturing cost.

Another object of the present invention is to improve the impact resistance of a connection structure of a frame and a primary suspension device.

To achieve the above object, the articulated frame linear motor bogie has a horizontal frame connected to a vehicle body, and a linear motor is suspended below the frame. The improvement is that the device is characterized in that,

the framework is provided with 2T-shaped frames which are hinged with each other, and the middle parts of beams at two sides of the frames are connected with a central beam through rubber nodes;

the central beam is connected with the traction beam at the upper part through a longitudinal pull rod at the side part, and the central pin respectively penetrates through the traction beam and the central beam to be connected into an integral structure;

the traction cross beam is respectively connected with the side beams of the 2T-shaped frames through the oil pressure shock absorbers;

In order to reduce the impact force generated to the bogie and the vehicle body when the vehicle runs, the side beams are respectively connected with the axle boxes of the front and rear wheel pairs through 2 side herringbone springs and 1 top laminated spring.

In order to improve the installation space design of the linear motor, 3 hanging devices used for hanging the linear motor are respectively arranged on the cross beams of 2T-shaped frames to form a triangular hanging structure in a plane. The hanging device can ensure the clearance of the linear motor and simultaneously play a role in vibration reduction, and a spiral lifting and gasket adjusting mode is adopted to play a role in height adjustment of the linear motor; meanwhile, in order to limit the free swing of the linear motor, the linear motor is connected to the lower part of the side beam of the framework through 2 transverse pull rods.
