BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a branching device for a tracked vehicle, and more particularly, to a device for guiding a vehicle by selecting a desired direction by a branching device (a branch selector) mounted on the vehicle, rather than moving the track for branching of the vehicle.

More specifically, the invention relates to a branching device for track vehicles having a branching device for branching in a desired direction from a branching point and a braking device for stopping at a desired location of the vehicle.

In the future, with the rapid development of science and technology and the improvement of living standards, passenger cars with no pollution are expected to become commonplace, and a typical passenger car is a railroad car that runs on elevated tracks, which are constructed at a constant height on the ground. Such a system using a tracked vehicle is commonly referred to as a Personal Rapid Transit (hereinafter referred to as a PRT system). The PRT system is equipped with a branching device for branching to a branch to be operated at a branching point and a braking device for stopping at a desired place.

In general, trains or tracked vehicles operate in a state where they cannot leave the track, so in order to change the position from one track to another, conventionally, not by a switching function of the body like a car, but by a special action on the track Switched Conventional branching devices typically consist of three parts: points, crossings and leads.

As described above, the general branching method of the tracked vehicle is shown well in FIG. 1. FIG. 1 is a general explanatory diagram of a method of guiding a vehicle in a desired direction at a crossroad by using a branching device 10 mounted on a vehicle instead of moving a track among branching methods of a tracked vehicle.
The vehicle which wants to branch to the right side (A) among the vehicles running on the track guides the vehicle to the right by pulling the right guideway 8 of the vehicle through the branch wheel 7a mounted on the right side of the vehicle and vice versa. The vehicle to branch to B) guides the vehicle to the left by pulling the left guideway 8 through the branch device 7b.

2. Description of the Related Art Conventional branching apparatus for a track vehicle for a PRT system is disclosed in FIGS. 2, 3 and 4.

In the conventional branching apparatus, as shown in FIG. 2, a cabin is seated in a guideway 8 having an upper opening and having a substantially rectangular space, and a main wheel (to the bottom of the guideway 8) in the inner main frame 10. 9a and 9b are positioned, and the side guide wheels (2a, 2b) are installed on the side, and the branch auxiliary wheels (1a, 1b) provided on the upper surface of the main frame 10 to move the branch installed in the guideway The wheels 1a and 1b are hooked to the guide rail 5 to branch.

In the conventional method, since the branch auxiliary wheels 1a and 1b and the lateral guide wheels 2a and 2b are independently installed, the number of wheels installed in the vehicle and the accessories are increased, and the guide rails installed in the guide roads are also increased. It must be installed in the direction opposite to the guide wheel of.

The conventional branching device shown in FIG. 3 is a branching method using magnetic attraction of the electromagnets 3a and 3b instead of the branching auxiliary wheel. To this end, magnetic materials 4a and 4b are installed on the sidewalls of the branch rails 5 in parallel with the electromagnets 3a and 3b. However, such a branching method by magnetic attraction has a disadvantage in that the system stability (fail-safe) is insufficient.

The conventional branch device shown in Figure 4
A part of the upper center portion of the guideway 8 is opened to form the transverse guides and the branch rails 5a and 5b, and the diverging and braking are simultaneously performed while the transverse guides and the branch wheels 16a and 16b are inserted and removed. The main arms 10a and 12b are installed on both sides of the main arm 10 so that the branch arms 12a and 12b are operated from both sides, and the main wheels 9a and 9b of the main frame 10 are the main wheel shafts 17a and 17b. And branching and braking devices provided with main wheel support portions 19a and 19b on the bottom side thereof.
However, due to the position of the rail for using the wheel and the braking device for lateral guidance and branching together, the cross section still has a disadvantage in that it does not secure a great advantage in terms of economics and the previous structures.

The present invention has been made to solve the problems of the conventional branching device as described above, by mounting a branch wheel on the branch arm connected to the branch actuator and a lateral guide wheel on the vehicle body to branch and guide the vehicle of one rail The purpose of the present invention is to provide a branching device for an orbital vehicle having excellent system stability by providing an emergency braking device using a hydraulic system having excellent stability, and improving economic efficiency by simplifying the structure of the guideway.

The track device branching device of the present invention for achieving the above object,

One pair extends downward from the upper surface of the guideway, the other pair protrudes from the sidewalls of the guideway and extends upwards with the transverse guides and branching rails, 90 ° from each other.

Is achieved as a branching device for a tracked vehicle.

Preferably, the branch wheel of the branching device for the tracked vehicle travels in a state in which the lateral guide and the branch rail are squeezed from both sides together with the lateral guide 고정 fixed to the main frame according to the branching direction of the vehicle. .

The branch arm of the branching device for a track vehicle of the present invention is preferably provided with a rotation guide arm for rotating and linearly moving the branch arm.

The track device for branching vehicle of the present invention is preferably installed between the rotation guide arm, it further comprises a worm gear for transmitting a rotational force to the rotation guide arm.

The brake rail of the branching device for a track vehicle of the present invention is the same as the lateral guide and the branch rail, and preferably has the feature of simultaneously performing the functions of the lateral guide, the branch and the emergency braking.

The branching device for a track vehicle of the present invention preferably prevents the branch rail and the brake caliper on the opposite side from escaping from the brake rail at the same time so that the brake caliper and the brake rail do not collide, and has a pair of left and right brake calipers at the rear of the vehicle. It is preferable to have four brake calipers, one pair left and one right, in front and rear of the vehicle.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 5 is a front sectional view of the transverse direction guide and branching device of the general driving state according to the present invention, Figure 6 is a plan view of the transverse direction guide and branching device of the general driving state according to the present invention.

As shown in FIG. 5, the guideway 8 also serves as a rail for lateral guidance and branching through a yaw-shaped cross section.
The mainframe 10 is equipped with main wheels 9a to 9d and four pairs of lateral guiding wheels 6a to 6d according to the present invention, and a pair of branching wheels 7a and 7b according to the present invention. It is connected to the actuator 11 via the rotation guide arm 51.

The lateral guiding wheels 6a to 6d form a sidewall of the yaw-shaped cross section and travel through a guideway 8 which serves as a rail for lateral guiding and branching, and the branching wheels 7a and 7b. ) Tracks the guideway 8 selectively according to the direction in which the track vehicle intends to branch. In the general driving section, four lateral guide wheels guide the vehicle in the traveling direction with only one branch wheel kept at a very small distance from the branch rail to ensure safety in case of system failure. This is a distinctive feature from the conventional methods, and the branch wheel is spaced apart from the branch rail even when the branch reference ratio is completed before entering the branch section.

In the branching section, branching in a desired direction is induced by using a branch actuator and a rotation guide arm mounted on the branching arm described later. Using the rotation guide arm and worm gear that can guide the rotational and linear motion of the branch arm, when the vehicle enters the division-based ratio section, the branching wheel opposite to the branching direction is pushed out so as not to contact the branching rail, and the branching direction It pulls the diverging wheel of and rotates to grasp the branch rail to guide the branch safely.

At this time, in the state where the branch wheel is completed, the branch wheel maintains a small distance from the branch rail. When the entrance is started when the branch section is reached, the interval is reduced by centrifugal force, and finally the branch rail is held to branch. This means that if one branch wheel always runs with a branch rail, there is a slight play in consideration of problems such as durability, vibration, straightness and efficiency.

Figure 7a is a perspective view showing a state in which the branching device according to the present invention branches to the left, Figure 7b is a perspective view showing a state in which the branching device according to the present invention branches to the right, Figure 12 is inducing branching of the vehicle A branch rail link assembly is shown.
Looking at the configuration of the branch rail link assembly based on the drawings as follows.

delete

The right branch rail 7a is connected to each other by the branch arm 12a, and the left branch wheel 7b is connected to each other by the other branch arm 12b. Both branching wheels 7a and 7b are mounted so as to maintain 90 ° to each other. Each of the branch arms 12a and 12b is provided with a rotation guide arm 51 to guide rotational and linear motions of the branch arms 12a and 12b, respectively. The rotation guide 121 guides the rotation guide arm 51 to induce rotation and linear motion.

In the present invention, using the hydraulic motor 122 that is reliable as a device for rotating the branch wheel link assembly in the desired direction, and easy to establish a failure countermeasures to increase the stability of the system. In addition, a worm gear 123 and 124 composed of the worm and the worm wheel were mounted in preparation for stopping the system when the system was completed or not completed. When an emergency occurs, the pressure valve of the hydraulic circuit to which the hydraulic motor 122 belongs detects this and not only shuts off the inlet and outgoing pipes of the hydraulic motor 122, but also the input side is not affected by the load on the output side of the worm gears 123 and 124. The stability of the system was secured using the

The branching process of the vehicle according to the operation of the aforementioned branch wheel link assembly is as follows.

First, when reaching the branch section of the vehicle in progress, the hydraulic motor 122 is operated to rotate the worm gear 124 through the worm 123 connected to the shaft of the hydraulic motor 122, the worm 123 The minimizing the box incorporating the branch wheel assembly with the hydraulic motor 122 was to be easily removable on the vehicle body.

The rotational force generated by the operation of the worm gears 123 and 124 is transmitted to the rotation guide arm 51. As the rotation guide arm 51 rotates, the branch arms 12a and 12b connected to the rotation guide arm 51 perform linear motion and rotational motion. Since the branch arms 12a and 12b on both sides are kept at 90 ° to each other, when the branch wheel connected to one branch arm catches the branch rail, the branch wheel connected to the other branch arm does not touch the branch rail. Such an operation is made possible by the rotation guide arm 51 rotating the branch arms 12a and 12b and inducing a linear motion to push and pull the branch arms 12a and 12b.

FIG. 7B illustrates an operating state of the branching device when trying to branch to the right side as opposed to FIG. 7A. In this case, only the diverging wheel that touches the branch rail is different, the other operation principle is the same as the operation principle shown in Figure 7a, so a detailed description thereof will be omitted.

8 shows a conventional emergency braking device used for a tracked vehicle. The conventional emergency braking device is provided with brake calipers 13a and 13b on both sides of the main frame, so as to hold the brake rail protruding from the side wall of the guideway. This conventional emergency braking device is difficult to maintain a constant positional relationship between the brake rail and the caliper (13a, 13b) by the vertical movement of the vehicle, deterioration of the braking performance while the foreign matter invaded from the outside piles on the brake rail There was a problem.

As shown in the drawings, in the emergency braking device according to the present invention, the brake calipers 91a and 91b have separate actuators. This is to operate independently in case of emergency.

The brake rail is not provided separately, and the guideway 8 simultaneously performs the function of the brake rail. The brake calipers 91a and 91b hold both side walls of the guideway 8. In the emergency braking device according to the present invention, since the lateral guide wheels 6a to 6d and the branch wheels 7a and 7b of the vehicle hold the guideway 8, the movement of the vehicle in the left and right directions is limited. In addition, since the calipers 91a and 91b grip the guideway 8 up and down even when the vehicle moves up and down, the guideway 8 and the calipers 91a and 91b do not collide without emergency braking. It can exert the function of.

The branching device for track vehicles, which combines the functions of lateral guidance, branching and emergency braking according to the present invention, is equipped with a guiding wheel on the branching arm connected with the lateral guidance and the branch rail and the worm gear to make branching and guidance of the vehicle extremely simple. It is economical and safe by implementing through guideway of structure.

In the emergency braking device according to the present invention, since the lateral guide wheel and the branch wheel of the vehicle hold the brake rail, the movement in the left and right directions of the vehicle is limited. In addition, since the caliper grips the brake rail up and down even when the vehicle moves up and down, the brake rail and the caliper can exhibit the function of emergency braking without collision.
