Abstract

The utility model relates to a joint type truss steering bogie. Two parts of T-shaped frames hinged with each other are used for assembling a truss which has a flexible conjunction to adapt to a curve with an abrupt bend angle, so as to increase the limit for the truss bearing the twist force and reduce the difficulty of designing the steering bogie and the requirement of the material. Two T-shaped frames are respectively provided with a beam and a side beam which are vertically connected, the beam and the side beam 22 of one of the two T-shaped frames are penetrated with the beam and the side beam of the other one of the two T-shaped frames, and the beams and the side beams are fixed and connected with a hinge structure which is arranged at the inner side of the truss in a diagonal mode. When a wheel pair runs to the curve with the abrupt bend angle, two hinge structures at the inner side of the truss can bear larger torque to twist properly, so as to have the random protective function on the truss.

Technical Field

The utility model relates to a bogie for rail vehicle specifically is to the improvement of framework structure, belongs to the machine-building field.

Background

The existing bogie applied to rail vehicles of 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. At the same time, the connection between the frame and the primary suspension is subjected to high impact forces at high vehicle speeds.

Therefore, the structural mode of the existing rigid framework is difficult to adapt to the working conditions to a certain extent, and has higher requirements on the manufacturing quality and the material of the framework, thereby increasing the design difficulty and the manufacturing cost.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an articulated frame bogie to solve above-mentioned problem and defect. The framework is assembled by adopting the mutually hinged 2-part T-shaped frames, so that the framework is provided with flexible connecting points to adapt to a curve with a relatively acute bending angle, the limit of the framework for bearing the twisting force is improved, and the design difficulty and the material requirement of the bogie are reduced.

To achieve the above design object, the articulated frame bogie comprises:

a horizontal frame having 2T-shaped frames hinged to each other. Wherein,

the 2T-shaped frames are respectively provided with a cross beam and a side beam which are vertically connected, the cross beam and the side beam (22) of the 2T-shaped frames penetrate through each other and are fixedly connected through a hinge structure, and the hinge structure is arranged on the inner side of the framework in a diagonal manner.

According to the integral scheme, when the wheel set runs to a curve with a relatively sharp bend angle, the 2 hinge structures on the inner side of the framework can bear relatively large torque and twist appropriately, so that the framework is protected randomly.

In order to improve the installation space design of the linear motor of the traction bogie, hanging devices for hanging the linear motor are respectively arranged at the 2 cross beams.

The hanging device is not described herein, and the structure of the hanging device may be selected according to the adjustment of the vertical height of the linear motor.

In order to improve the longitudinal traction effect of the linear motor on wheel pairs through a bogie, the 2 side beams are respectively connected with the front axle box body and the rear axle box body through longitudinal pull rods.

In order to reduce the impact force formed to the bogie and the vehicle body when the vehicle runs, the 2 side beams are respectively connected with the front axle box body and the rear axle box body through rubber piles.

In addition, a detailed structure may be adopted in which anti-roll torsion bars for connecting the vehicle body are connected to the outer side portions of the 2 side members, respectively.

As mentioned above, the articulated frame bogie has the advantages that the frame is assembled by adopting the 2 parts of T-shaped frames which are hinged with each other, so that the frame has flexible connection points, can adapt to an operation curve with a relatively sharp bend angle, better improves the capability of the frame for bearing the twisting force, and reduces the design difficulty and the material requirement of the bogie.
