Embodiment 1

[0021] Example 1: Refer to the attached Figure 1-7 . Such as figure 1 As shown, the structure of the maglev bogie is mainly composed of component 1, wheel set 2, driving and braking device 3, guide wheel device 4, stabilizer wheel device 5, traction and side block device 6 and other parts. This bogie is suitable for the use of medium and low speed maglev line engineering vehicles for vehicles to run on the maglev rail row. The bogie running wheels act on the non-sensing surface of the track F rail to drive the bogie to travel; the guide wheels and the stabilizer wheels act on the side and bottom surfaces of the F rail respectively to provide guiding capabilities for the bogie and prevent overturning.

[0022] The frame 1 adopts a "well" shape welded by plates and consists of two parts: a beam and a side frame. The use of high-strength plates for welding can effectively reduce the weight of components. The lower part of the beam is mainly used to install the walking wheel set ...

Abstract

The invention relates to a bogie structure for a magnetic levitation engineering vehicle, which can effectively reduce the axle load and the track surface bearing, improve the running stability and comfort of a bogie, and meanwhile, effectively reduce abrasion to the side face of an F rail and damage to a rail face by walking wheels. The bogie structure is of a #-shaped structure when overlooked and is composed of a cross beam and side frames. The lower portion of the cross beam is used for installing walking wheel sets, the wheel sets are arranged in a mode in which the wheels rotate and theaxles are fixed, and the wheels are in bolted connection with hubs. Traction and side blocking devices are installed on the upper portion and the middle area of the cross beam, driving and braking devices are installed on the outer sides of the wheels of the wheel sets, hydraulic motors or driving motors are in bolted connection with wheel frameworks to drive the wheels to rotate, and the hydraulic motors or the driving motors can be provided with braking devices to provide traveling and parking braking for the bogie. Four groups of guide wheel devices are configured for each bogie and are arranged at the positions of the side frames around the structure, and four groups of stabilizing wheel devices are configured for each bogie and are arranged at the bottoms of the side frames around thestructure.

Description

Technical field [0001] The invention relates to a method that can effectively reduce the axle load and the load on the track surface, and can also improve the stability and comfort of the bogie operation, and at the same time can effectively reduce the wear on the side of the F rail and effectively reduce the damage of the traveling wheel to the track surface The bogie structure used for maglev engineering vehicles belongs to the field of bogie manufacturing for maglev engineering vehicles. Background technique [0002] CN106476832A, the name "a maglev rail vehicle bogie", includes a frame with side beams and cross beams, and multiple sets of wheel-set axle box devices for walking on the F rail skid support surface installed under the frame; characterized by , It also includes a plurality of guide devices installed on the outside of the frame side beams, a primary suspension device installed between the frame and the wheelset axle box device, and a secondary suspension device ins...
