Detailed implementation manners

[0035] The core of the present application lies in disclosing a permanent magnet suspension monorail vehicle bogie to simplify the structure of the bogie and improve the running smoothness of the vehicle.

[0036] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0037] As Figure 1 shown, the embodiments of the present application disclose a permanent magnet suspension monorail vehicle bogie, including a bogie frame 1 and a suspension device 3.

[0038] Among them, a motor 5 is installed on the top of the bogie frame 1, and the motor 5 is a linear motor. Along the longitudinal direction of the bogie frame 1 (i.e., Figure 2in the y - direction shown in the figure), at both ends of the bottom of the bogie frame 1, a braking device 6 and a guide wheel 4 are provided. The braking device 6 provides a braking function for braking when the vehicle arrives at the station and for emergency braking in case of an emergency. The number of guide wheels 4 at any one end in the longitudinal direction of the bogie frame 1 is one, that is, a single - side single - guide - wheel 4 scheme is adopted. Safety wheels 2 are installed around the bottom of the bogie frame 1. The axis of the guide wheel 4 and the axis of the safety wheel 2 are arranged perpendicularly. Figure 1 The axis of the safety wheel 2 shown in the figure is arranged along the transverse direction of the bogie frame 1 ( Figure 2 in the x - direction shown in the figure), and the axis of the guide wheel 4 is arranged vertically.

[0039] The braking device 6 includes four groups and adopts the rail - clamping braking method. Specifically, the braking device 6 includes a brake cylinder, a brake caliper, and a brake block. During braking, the brake cylinder pushes the brake caliper so that the brake block and the brake rail are mutually extruded, and deceleration or stopping is achieved through frictional force. The guide wheel 4 and the braking device 6 share the brake rail. The brake rail refers to the part of the track directly extruded by the brake block during braking and belongs to the functional area of the track beam. The guide wheel 4 and the braking device 6 share the side contact surface of the same track beam. This method can reduce the overall height of the bogie and the track beam.

[0040] A current - collecting device 32 and a permanent - magnet suspension device 7 are installed at the bottom of the bogie frame 1. The permanent - magnet suspension device 7 includes a permanent magnet 30. The current - collecting device 32 can realize the electrical energy transmission between the vehicle and the ground power supply system and provide stable power for on - vehicle equipment. The motor 5 and the windings in the track beam act to generate a driving force to drive the vehicle to run, and the permanent magnet 30 and the magnets inside the track beam act to generate a suspension force.

[0041] The suspension device 3 includes a suspension beam 23. The suspension beam 23 is connected to the bogie frame 1 through a suspension pin. The suspension beam 23 can swing around the suspension pin. The suspension beam 23 is connected to the vehicle body through a hanger 22 and a traction link 20. Specifically, the hanger 22 is connected to the vehicle body through bolts. Traction - link mounting seats for installing the traction link 20 are provided on both the suspension beam 23 and the vehicle body.

[0042] The working process is as follows: When traction is carried out, the motor 5 and the windings in the track beam act to generate a driving force to drive the vehicle to move. The permanent magnet 30 and the magnets inside the track beam act to generate a suspension force to make the vehicle suspended, avoiding direct contact between the bogie and the track beam. When the vehicle passes through a curve, the guide wheel 4 contacts the side of the track beam to provide a guiding force to make the vehicle run along the track direction. During braking, the braking device 6 acts on the brake rail to generate a braking force to make the vehicle stop running.

[0043] In the bogie of the permanent magnet levitation monorail vehicle disclosed in the embodiments of the present application, one motor 5 is provided and placed on the top of the bogie frame 1, and the permanent magnet 30 is arranged at the bottom of the bogie frame 1, which can simplify the internal structure of the bogie frame 1 and reduce the strength design of the bogie frame 1; a total of two guide wheels 4 are provided, and a single guide wheel 4 is arranged on one side of the bogie frame 1, reducing the number of guide wheels 4; the guide wheel 4 and the braking device 6 share a braking rail clip, which can simplify the structure of the bogie frame 1 and reduce the overall height of the bogie and the track beam. In the bogie of the permanent magnet levitation monorail vehicle disclosed in the embodiments of the present application, the structure of the bogie is more simplified and more compact, which can improve the reliability and safety of vehicle operation.
