Detailed Description

Example 1: reference is made to figures 1 and 2. An articulated power bogie suitable for an articulated electric monorail overhead tourist car is mainly used for the articulated carriage position of the articulated electric monorail overhead tourist car and is arranged between two adjacent carriages when in use, and the bogie can effectively meet the requirements of the articulated vehicle on the degree of freedom, the rigidity and the like;

during assembly, firstly completing assembly of a walking device assembly 1-1, welding of a bogie frame 1-2, machining and coating, assembly of a stabilizing wheel assembly 1-3, assembly of a guide wheel assembly 1-4 and assembly of a swing bolster assembly 1-6; after the detection, firstly installing the power walking device 1-1 on a bogie frame 1-2, installing a central traction device 1-7 in the center of a bogie frame, symmetrically placing the finished components on a standard track beam in a left-right mode, symmetrically installing guide wheel assemblies 1-4 on the left side and the right side, and checking the frame symmetrically again after the completion; and then the stabilizing wheel assemblies 1-3 are arranged on the assemblies, and the stabilizing wheels need to be adjusted again after the whole vehicle is completely dropped because the bogie is in an unloaded state in the installation process and the vertical load is only the load of the bogie. Finally, mounting a spring group in the suspension device on the assembly, mounting the swing bolster assemblies 1-6 in the assembly, and paying attention to the mounting of the central traction pin shaft during mounting; after the operation is finished, the swing bolster and the framework are pre-fixed by using the long bolt, and the long bolt is removed after the car is dropped. Completing the initial assembly of the bogie; when the vehicle falls, the bogies are arranged on the standard track beam according to the sequence and distance requirements, and when the vehicle falls, the front and the back of each vehicle body are respectively connected with a hinged flange which releases the rotation around the y axis and a flange which releases the rotation.

When the bogie is finished and the whole vehicle is dynamically debugged or operated, the traction braking force generated by the power walking device 1-1 is transmitted to the bogie frame 1-2 through the mounting seat, the traction braking force between the bogie frame 1-2 and the swing bolster assembly 1-6 is transmitted to the swing bolster assembly 1-6 through the central traction device 1-7, and finally transmitted to the vehicle body through the hinged mounting seat on the swing bolster assembly-6.

When a vehicle runs on a road, the vehicle can be subjected to passive transverse force, the transverse force comes from side wind, inertia force and the like, the transverse force of a vehicle body is transmitted to the swing bolster assemblies 1-6 through the hinged mounting seats, transmitted to the bogie frames 1-2 through the central traction devices 1-7 and finally transmitted to the track beam through the guide wheel assemblies 1-4 arranged on the bogie frames, and the transverse force is specially transmitted; when the vehicle passes through a curve, the required steering torque is transmitted through the process, and only the four guide wheels are different in stress condition to form steering bending moment.

The guide wheel assembly is shown in fig. 3. The device comprises a wheel component 4-1, a guide wheel framework 4-2, a pressing block 4-3, a rubber block 4-4 and an adjusting pad 4-5; the wheel assembly 4-1 is composed of a polyurethane wheel, a bearing, a guide wheel shaft and the like and is installed; when the guide wheel assembly is installed, the adjusting pad 4-5 and the forward rubber block 4-4 are installed on the guide framework 4-2, the finished wheel assembly 4-1 is installed on the guide framework, and finally the pressing block 4-3 is installed. The principle is as follows: when the vehicle runs, the guide wheels need to be in contact with the rail beam web plate to generate positive pressure, so that on one hand, the transverse force of the vehicle is resisted, and on the other hand, the positive pressure and the positive pressure of other guide wheels arranged on the same bogie form a guide moment to force the bogie to run along the line; the guide wheel is designed in a vibration damping slideway mode, when the outer width of a web plate of a box-type track beam changes within a certain range in the running process of a vehicle, the guide wheel can enable a 4-1 wheel assembly to be in good contact with the web plate of the track beam through the pre-pressure of a 4-4 rubber block, and meanwhile, when the web plate is staggered, the 4-4 rubber block can also be extruded or released through the process of staggering, so that the trafficability is ensured, and meanwhile, the 4-4 rubber block can also reduce the noise between tracks; 4-3, the briquetting is also provided with a small piece of rubber, so that the two-way vibration reduction and noise reduction effects can be effectively realized in the vehicle vibration process; the running quality of the vehicle is improved.

Lateral bending moment generated by transverse force of a vehicle body is transmitted to the swing bolster assemblies 1-6 through the hinged mounting seats, transmitted to a bogie frame through the damping springs of the suspension devices 1-5 on the left side and the right side and the central traction devices 1-7, and then formed into resistance overturning bending moment through the stabilizing wheel assemblies 1-3 mounted on the bogie and running tires, so that balance of the vehicle is kept.

The suspension device 1-5 installed between the bogie frame 1-2 and the swing bolster 1-6 is composed of a spring device (not limited to a cylindrical spring) and an oil pressure damper, and the central traction device 1-7 contains a circular rubber device, so that the upper and lower, side rolling, longitudinal, transverse and other impact vibrations from the track can be effectively relieved and attenuated together, and the vehicle comfort is provided.

In the swing bolster assemblies 1-6, the release rotating bearing around the Y axis adopts a rubber bearing, so that the side roll of a single-section carriage is prevented from driving all carriages of the whole vehicle to roll, and the side roll impact of the vehicle during the bending in and out can be reduced.

It should be understood that: although the above embodiments have described the design idea of the present invention in more detail, these descriptions are only simple descriptions of the design idea of the present invention, and are not limitations of the design idea of the present invention, and any combination, addition, or modification without departing from the design idea of the present invention falls within the scope of the present invention.
