Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is applied to a non-adhesive type of transportation, and is directed to a non-adhesive type of transportation system, which uses a traction force generated on the ground, that is, a running cable, an electromagnetic force, etc., to cause the vehicle to run. This relates to a towed element that is attached to a vehicle when necessary.

<Prior Art> In conventional non-adhesive transportation systems, the towed element is fixed to the vehicle body.

<Problems to be Solved by the Invention> When the vehicle passes through a curved section, the central portion of the vehicle in the longitudinal direction is closer to the inside gI with respect to the track.

For this reason, (1) When a towed element grabs a cable running on the ground and the vehicle runs, a lateral force from the cable acts on the towed element in a curved section, and this lateral force must be counteracted. , it became necessary to increase the strength of the towed element.

The weight of the towed element increases significantly.

This increases acceleration resistance and power The disadvantage is that consumption increases.

(2) When a vehicle runs due to magnetic interaction between a magnetic force generating device installed on the ground and a magnetic force generating device attached to a towed element, multiple towed elements are usually attached to the vehicle body. In this case, the mutual positions of each towed element and the magnetic force generator on the ground are not optimal.

Since the force between the magnetic forces is greatly influenced by their mutual positions (distance), there is a drawback that the traction force fluctuates, leading to a loss of power, and at the same time making the ride uncomfortable.

Means for Solving the Problems> The present invention eliminates the above drawbacks, has many features such as low construction and maintenance costs, and allows for more reliable and safe unmanned operation. Therefore, we are trying to regenerate the non-adhesive transport system 111, which was rarely used in the world, and offer it to the world.

That is, each towed element individually slides in the left and right directions with respect to the traveling direction of the vehicle, and its position in the left and right direction is determined by a sensor that searches for an optimal position or by a guide rail installed on the ground. In the case of using guide rails, each towed element is equipped with a small wheel, etc., and the small wheels, and therefore each towed element, slide left and right along the guide rail with respect to the direction of travel of the vehicle to obtain the optimum position for each. .

At branch points on routes, the guide rails may be of a flexible type. This flexible guide rail is bent left and right according to the branching direction of the vehicle, guides the towed child, and passes it to the next fixed guide rail.

This flexible guide rail can also guide vehicles at branch points of the route.

In this way, by using the sliding retractor according to the present invention, the vehicle can easily pass through a small radius of curvature even in a non-adhesive type of transportation, and it is possible to easily pass through a small radius of curvature. It becomes possible to take advantage of many of the above-mentioned advantages that institutions do not have.

<Example> The sliding retractor according to the present invention will be described in detail below using examples thereof.

Reference numeral 3 indicates a wheel, and 3 indicates a guide tire when the wheel is a rubber tire. Since these are known, illustration thereof will be omitted below. 4 is a track, 5 is a sliding towed element according to the present invention, 6 is a floor plate of the vehicle body, and 7 is a towed element suspension frame for suspending the sliding towed element, which is fixed to the floor plate 6 of the vehicle body.

One or more sliding towed elements 5 are suspended depending on the traction force.

FIG. 2 is a cross-sectional view taken along a plane parallel to the traveling direction of the vehicle and perpendicular to the ground, where 5 is a sliding towed element, 6 is a floor plate of the vehicle body, and 7 is a towed element suspension frame. The sliding towed element 5 may be equipped with small wheels, a cable gripping device, a magnetic force generator, etc. for sliding the towed element left and right with respect to the direction of travel of the vehicle along a guide rail installed on the ground, depending on the purpose. Attach each.

The towed child suspension frame 7 includes a bearing to reduce the frictional force between the towed child and the towed child suspension frame when the towed child slides left and right, and a bearing to prevent the towed child from being supported from the ground. When transmitting the traction force to the towed child suspension frame, a spring or the like is placed to reduce the impact.

Figures 3 [21 and 4] show the vehicle passing through a curved section when the cable running on the ground is gripped by a single cable device attached to a towed element to cause the vehicle to run.

Figures 5 and 6 show the case in which a vehicle runs due to magnetic interaction between the magnetic force generated by a magnetic force generator fixed on the ground and the magnetic force generated by a magnetic force generator attached to a sliding towed element. FIG. 5 shows the curve passing through Y- in FIG. 1.

<Function> Next, the function of the embodiment of the sliding retractor according to the present invention will be described.

When using a running cable: This will be explained with reference to FIGS. 3 and 4.

On straight sections of the route and curved sections with a large radius of curvature, the sliding towed element 5 slides left and right with respect to the traveling direction according to the position of the cable, receiving only the traction force from the running cable and not receiving any lateral force. , in a curved section with a small radius of curvature, the sliding towed element 5 slides left and right according to the guide rail 11,
The lateral force is transmitted to the guide rail 11, and the sliding towed element 5 does not receive any lateral force.

When using magnetic force: This will be explained with reference to FIGS. 5 and 6.

The distance between the magnetic force generator 14 attached to the sliding towed element and the magnetic force generator 15 installed on the ground can be kept constant over the entire route regardless of the radius of curvature of the route.

<Effects of the Invention> The effects of the sliding retractor according to the present invention whose structure and function have been described in detail above are listed below.

When using a running cable: (1) Since the sliding towed element is not subjected to lateral force, it becomes possible to reduce the weight, and therefore the vehicle becomes lighter. This reduces vehicle manufacturing costs.

(2) Vehicles can pass through a smaller radius of curvature than before.

When using magnetic force: (1) Vehicles can pass through a smaller radius of curvature than before.

(2) The gap between the magnetic force generator attached to the sliding towed element and the magnetic force generator on the ground side when the vehicle passes can be set to about 5 mm, compared to 1 cm or more in conventional transportation systems of this type. It is possible to obtain several times the traction force with the same amount of power.

The above-mentioned effects enable the practical use of non-adhesive transportation devices in a wider range, and the non-adhesive transportation devices have the following characteristics, which are the ripple effects of the present invention.

(1) Since no driving device is mounted on the vehicle, the vehicle becomes lighter and the driving power cost is reduced. Also, if the track is elevated, the construction cost is reduced.

(2) Since vehicle operation control is performed on the ground side, there is no need to make the control device smaller and lighter, which reduces device costs.

(3) Strong against slopes and snow.
