Abstract

PURPOSE:To reduce the material of laying reaction plates and the laying labor by varying an interval of reaction plate members in response to the traveling zone of a linear motor car. CONSTITUTION:The primary side electromagnetic unit 4 of a linear motor car is placed on the linear motor car 1 to oppose to the ground, and reaction plates 5 are laid in parallel between rails 3a and 3b on the ground to oppose to the unit 4. The plates 5 are formed by aligning a plurality of plate members 6 unitized in the determined same length L in the traveling direction, and aligned intermittently at an interval l between adjacent plate members 6. The interval lis narrow in the accelerating zone (a) which needs large propulsion force and wise in an idling zone (b) which does not neccessitate large propulsion force.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a running path on which an on-board linear motor car runs, and particularly relates to a linear motor car in which the installation of a reaction plate, which is a secondary conductor of a linear motor, is improved. This relates to the driving route.

[Background of the invention]

Conventionally, reaction plates, which are the secondary conductors of linear motors, have been installed continuously along the entire length of the traveling route of linear motor cars. (Actual publication 1972-11691
(Publication No. 3) Therefore, on railways with long running distances, installing reaction plates requires a lot of materials and labor, which increases equipment costs, so they are only practical in limited sections with running distances of several hundred meters. It had been.

[Purpose of the invention]

The object of the present invention is to provide a running route for a linear motor car that reduces equipment costs.

[Summary of the invention]

The present invention was developed by focusing on the fact that when a linear motor car runs on a running track where reaction plates are installed continuously, it travels by repeating coasting and coasting, and the reaction plate is not required. The above objective was achieved by thinning out the reaction plates in the coasting section where the vehicle does not run and installing them intermittently to shorten the total length of the reaction plates in the running section.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

As shown in FIG.
Unitized reaction plates 2 having a length L are disposed intermittently at appropriate intervals t in the center thereof. When the linear motor car 3 travels on this travel path, the speed ranges from speed Vl to speed V2, as shown by speed line 5 in FIG. 2. In other words, while the linear motor is on the reaction plate 2, the linear motor car 3 is accelerated and the speed increases from Vl to V2, and coasting occurs during the interval when the reaction plate 2 is missing, and the speed increases from ■2 to Vl. When the speed drops to 1, the speed is accelerated by the next reaction plate 2, and the vehicle travels at an average speed between 1 and 72.

In addition, in a vehicle formation in which a plurality of linear motor cars 3 are connected, as shown in FIG.
By laying the reaction plates 2 at intervals 21 so that one of the linear motors always engages with the reaction plate, it is possible to run without reducing speed.

Therefore, when choosing a place that requires a large propulsion force, such as near a stop or on a slope, shorten the interval between missing reaction plates.
The running route is designed with reaction plates installed depending on the required propulsion force, such as by increasing the gap between reaction plates.

According to this embodiment, the total length of the reaction plates between the running zones □ of the linear motor car is very short.
This has the effect of greatly reducing equipment costs.

〔Effect of the invention〕

According to the present invention, the total length of the reaction plates of the running path is not much shorter than the running section, and this has the effect of significantly reducing equipment costs, such as saving materials and shortening the installation period. be.
