Description

[Detailed description of the invention] Levitation for magnetic railway systems with servo motor actuated air gap control device 1 The present invention relates to a floating type traveling bogie for a magnetic railway transportation system that is constrained to a gauge. The present invention relates to an air gap control device used for. Such magnetic rail transport system In this case, the vehicle is driven via a long stator motor installed on the road. child The moving electric field formed in the windings of the long stator motor of Works with the magnetic force of a magnet. Such collaboration takes place without contact.

Such non-contact (air gap) must be reliably guaranteed, it At the same time, through the adjusting track (in this case, the thin plate unit of the long stator) Due to the acting magnetic force, the vehicle weight is distributed according to area over the entire length of the magnetic strip is transmitted to the road as a load. Such an air gap is related to the load must be adjusted by air gap control.

In other words, the air gap increases the load/weight increase (load increase on the running road). (large) and must be reduced by a servo motor, so that the levitated Magnetism between the permanent magnet of the bogie and the running track rail with a built-in long stator Qi suction power increases. Load-related mechanical air gap control and electronic controls Controlled support and guidance systems are known. This mechanical air gap control device are complex, expensive, have limited functionality and poor Il alignment. potential and a wide am variation range. Electronically controlled support and guidance system The stem is still complex and is only economical for high speed applications. The problem is that it is simple, inexpensive, and highly tunable. To provide an air gap control device having only a small adjustment variation range. That is. This object is achieved based on the features of claim 1. Compatible composition and and/or refinements are described in the claims 2 et seq.

In the following, embodiments of the invention will be explained in detail with reference to the drawings.

Jllm is equipped with an air gap control device according to the invention in cooperation with a magnetic railway track. This shows a part of the floating bogie of the magnetic railway vehicle that was developed.

FIG. 2 shows a plan view of the floating traveling trolley shown in FIG. 1.

A magnetic railway track consists of a track support and a track profile. Runway support is composed of a support molding 11 and a lateral binding material 12. The running track forming material is It has a holding rail 21, a side guide molded material 22, and a long stator 23.

The floating traveling trolley includes a layered frame 31, a spindle drive device 32, and a servo motor. 321, the upper vertical roller 33, the lower vertical roller 34, and the side guide. It has a roller 35 and a magnetic strip 36. N air railway cab (not shown) , for example, the rigid frame 31 via the air spring bellows 45 and the rotating ring 44. According to the invention, the air gap control may be coupled to the load-related This is performed using the servo motor 321 based on the standard setting value. Servo motor 3211 ;l At the ends of the longitudinal support provided on the one-sided traveling bogie frame 31, on both sides. each installed. This servo motor is operated via a spindle drive device 32. The distance between the magnetic strip 36 of the floating traveling truck and the long stator 23 is electronically controlled. in this case, the control is rigidly attached to the rigid frame 31. A pre-given value for the upper vertical roller 33 (non-height adjustable) It is carried out according to the allowable load value.

The load on the upper vertical roller 33 is determined by a force measuring device, for example a load cell. be measured. This results in an adjustable load transfer of the vehicle weight to the roadway supports. A minimum load on the vertical rollers 33 is ensured by means of the vertical rollers 33. Furthermore, according to the present invention The air gap control device shown in FIG. It becomes possible to configure the rigid frame 31 so that such a free chamber is generated. child As a result, the point intermediate track portion of the magnetic railway track and the crossing intermediate track Even though both running track parts protrude beyond the running track forming material upper binding part. It is possible to configure the magnetic railway vehicle so that it can run without any trouble.

The distance between the long stator 23 and the magnet strips 36 can be increased. It is particularly advantageous if the device 32 is constructed on the spindle. In this case, longs Based on the separation of the electric field of theta 23 and the magnetic field of the permanent magnet of the magnet strip 36, , the flow of power is interrupted, which for example Reliable drive cut-off can be performed under other requirements. This is due to driving luck. This is extremely important for the safety of traffic and vehicle handling operations. This allows the drive system to It becomes possible to run various vehicles with the same converter range of the system. The result As a result, given the possibility of drive cut-off of individual vehicles, these It is now possible to stop both cars at small intervals, which in turn reduces the length of the stopping track. A significant reduction is possible.

The support arm of the magnetic strip 36 is positioned on the upper running surface of the support rail 21. A predetermined support point (not shown), which is necessary to ensure drive cut-off, The weight of the vehicle is supported on the upper support rail 21 at the maximum distance Support points positioned such that complete load extinction of the side vertical rollers 33 is achieved Another advantageous configuration is obtained by having the . This results in a relatively long Even during a short pot life, deformation of the elastic running surface of the vertical roller is avoided. However, Since flat spots are avoided, the driving characteristics are improved. vehicle weight saw Such supports also act as stopping brakes to ensure that the vehicle comes to a stop. . The above configuration is only an exemplary description; for example, the magnet strip 36 may also be a rigid frame. The air gap control device controls the height of the upper vertical roller 33. It may be carried out by Sakoshi f.
