Description

Statement

Rail vehicles Technical field

The present invention relates to a vehicle (railway vehicle) traveling on rails, and more particularly to a rail traveling vehicle capable of providing smooth traveling while maintaining an appropriate gripper between the rails. It is. Background art

In a vehicle traveling on a rail, if the grip force, which is the frictional resistance between the drive wheel and the rail, is small, the traveling of the vehicle may be hindered. For example, in rainy weather, slippage occurs on the rail surface, which is particularly problematic when traveling on inclined rails.

To solve this problem, the drive wheel can be pressed against the rail to increase the grip force between the drive wheel and the rail.However, an excessive increase in the grip force increases the energy required for the vehicle to travel. However, there is a risk that efficient driving cannot be provided.

In order to generate an appropriate grip force, it has been proposed to use control means for detecting the weight of the vehicle with a detection means and changing a panel constant of a panel member for pressing a wheel against a rail, but the control is complicated. And increase the cost of the entire orbital system.

Further, in the track device of a traveling body traveling on a rail described in Japanese Patent Application Laid-Open No. 3-06-06, a driving wheel rolling on the upper surface of the rail 1 as shown in FIG. A traveling body 100 is used which has a pair of auxiliary wheels 1 20 which rolls on the lower surface of the rail 1 1〇 and which holds the rail between the driving wheel and the auxiliary wheels. The rail width is designed to be different from the straight part so that the amount of overlap of the auxiliary transport with respect to the lower surface of the rail is less than a certain value. Excessive reaction force is applied to the driving wheels 110 and the auxiliary wheels 120. This allows the vehicle to run on rail 1 smoothly.

However, in such a track device, it is necessary to manufacture rails having different widths for each curve area of the rail. When designing a track with many bushings, it is inevitable that the cost of the entire track device rises. In this way, considering the cost performance of the entire track system, the introduction of expensive control means from the viewpoint of realizing smooth running of the vehicle while maintaining an appropriate gripping force on the wheel rail, There is still room for improvement in conventional rail vehicles and systems using techniques such as rail design changes. Disclosure of the invention

The present invention has been made in view of the above-described problems, and has as its object to provide an appropriate grip force based on the total weight of a vehicle (including a load) despite a relatively simple configuration. It is an object of the present invention to provide a rail traveling vehicle that can be generated between wheels (drive wheels) and rails to realize efficient and smooth traveling.

That is, the rail running rain is held by the base and the base so as to be rotatable on the upper surface of the rail, and the pair of first wheels and the first wheel arranged apart from each other in the rail extending direction. It has two wheels, a third wheel held on the base so as to be rotatable on the lower surface of the rail, and a motor for driving at least one of the first and second wheels. The first wheel is located between the second wheel and the third wheel in the direction in which the rail extends, and the second wheel is held on the base via the buffer.

According to the present invention, when a shock absorber such as a coil spring loaded with the load of the vehicle and its load is elastically deformed downward, the vehicle moves so that the second wheel side of the base on which the shock absorber is disposed approaches the rail. Take a leaning posture. At this time, the third wheel, which is located on the opposite side of the second wheel via the first wheel, is pressed against the lower surface of the rail by the principle of leverage using the contact point between the first wheel and the rail as a fulcrum. As a result, the rail is sandwiched between the first wheel and the third wheel, that is, a grip force is obtained, and the amount of elastic deformation of the shock absorber according to the magnitude of the load received from the vehicle, that is, the vehicle Therefore, according to the rail grip mechanism of the present invention, it is possible to provide an appropriate grip force in accordance with the vehicle weight by Jg, thereby detecting the load of the vehicle and connecting the wheels to the rail. Without using a special control device to change the spring constant of the spring member to be pressed, the elastic deformation capacity of the shock absorber and the mounting position of the third wheel can be set appropriately to reduce the weight of the vehicle (including the load). Moderate grip force The wheels and the rail , And as a result, smooth and efficient running can be realized.

In a preferred embodiment of the present invention, the distance between the first wheel and the center of gravity of the running rail traveling vehicle is longer than the distance between the second wheel and the center of gravity, and the distance between the third wheel and the center of gravity is Is preferably shorter than the distance between. In this case, by providing the second wheel in the vicinity of the center of gravity of the vehicle, the buffer can be elastically deformed more effectively in the inclined area of the rail and the like, and a grip force can be obtained.

The third wheel is preferably composed of at least two wheels arranged apart from each other in the direction in which the rail extends. In this case, a plurality of third wheels are brought into contact with the lower surface of the rail to increase frictional resistance, thereby further improving the grip performance of the rail.

Further, it is preferable to include an auxiliary wheel held on a base so as to be rotatable on the side surface of the rail below at least one of the first wheel and the second wheel. This lifting can further improve the running safety of the vehicle by guiding the first wheel and the second wheel so as not to derail from the rail.

Further features of the present invention and the advantages it provides will be more clearly understood from the best mode for carrying out the invention described below with reference to the accompanying drawings. Brief Description of Drawings

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

As shown in FIGS. 1 and 2, the rail traveling vehicle 10 of the present embodiment can travel on a pair of rails 1 extending substantially in parallel in two directions, forward and backward. 11, a body 12 arranged on the base and constituting a passenger compartment, a pair of first wheels 20 held on the base so as to be able to run on the upper surface 1a of the rail 1, and a first wheel 20 extending in the rail extending direction. A pair of second wheels 30 arranged apart from one wheel and held on the base so as to run on the upper surface 1a of the rail 1, and a pair of second wheels 30 held on the base so as to run on the lower surface 1b of the rail 1 Of the third wheel 4〇, the four auxiliary wheels 50 held on the base so as to be able to run on the side surface 1c of the rail 1 below each of the first and second wheels, and the first wheel 20 And a driving motor 22. As shown in FIG. 3, the first wheel 20 is located between the second wheel 30 and the third wheel 40 in the direction in which the rail 1 extends, and each of the second wheels 30 is a cushioning member such as a coil spring. It is held in base 1 1 through 2.

As shown in FIGS. 4 and 5, the rail 1 has an H (I) -shaped cross section including a vertical plate-like web 2 and a horizontal plate-like flange 3 integrally connected to upper and lower ends thereof. . The rails can be laid along a desired track by integrally connecting the rails with a connecting member (not shown).

As shown in FIGS. 1 and 2, the body 12 provides a cabin space inside, and has bumpers 13 at front and rear ends thereof, and windows 14 at front, rear, left and right. In the present embodiment, the entrance door 15 is provided above the first wheel, and the seat 16 is arranged mainly above the second wheel 30 of the base 11.

As shown in FIG. 4, in the present embodiment, the first wheel 2〇 is a tire made of an elastic material such as a rubber tire. The rotary shaft 21 that connects the pair of first wheels is held by a bearing 24 provided on the lower surface of the base 11. The rotation output of the motor 22 disposed on the upper portion of the base is transmitted to the rotation shaft 21 of the first wheel via power transmission means including the belt 25 and the pulley 26. Thus, in the present embodiment, the first wheel 20 is a drive wheel.

As shown in FIG. 5, in the present embodiment, the second wheel 30 has an elasticity such as a rubber tire. This is a tire made of a conductive material. The shaft 31 connecting the pair of second wheels 30 is held by a bearing 33 provided on the lower surface of the base 11. In addition, the bearing portion 33 is connected to the base via the buffer 32. As a result, when the buffer body 32 is elastically deformed, the entire rail traveling vehicle can take an inclined posture such that the second wheel side of the base 11 approaches the rail. Since the rotation output of the motor 22 is not transmitted to the second wheel 30, the second wheel is a driven wheel in the present embodiment.

As shown in FIGS. 3 and 4, in the present embodiment, the third wheel 4 # is a tire made of an elastic material such as a rubber tire. The pair of third wheels 4〇 is rotatably held near the front ends of a pair of frames 4 hanging from near both side edges of the base 11. The length of the support member is determined such that when the first wheel 20 contacts the upper surface 1a of the rail 1, the third wheel 40 contacts the lower surface 1b of the rail 1. In the figure, reference numeral 42 denotes a reinforcing member provided between the lower end of the frame 41 and the lower end of a seventh auxiliary frame 51 that holds an auxiliary wheel 50 described later.

In the present embodiment, the auxiliary wheel 50 is a tire made of an elastic material such as a rubber tire. Each auxiliary wheel 50 is rotatably held near the tip of the auxiliary frame 51 so as to run on the side surface 1 c of the rail 1, that is, the surface of the web 2. Guide so that it does not derail from rail 1. In the present embodiment, a part of the frame 41 holding the third wheel 4〇 is used as a part of an auxiliary frame for holding the auxiliary wheel 50 located below the first wheel.

With reference to FIG. 6A and FIG. 6B, a description will be given of a mechanism in which the rail traveling vehicle of the present invention having the above configuration generates a rail gripper. As shown in FIG. 6A, when the rail traveling vehicle 10 is in a horizontal position on the rail 1, the first wheel 2〇 and the second wheel 30 that contact the upper surface of the rail and the third wheel 30 that contacts the lower surface of the rail. Since the rail 1 is sandwiched between the wheels 40 from above and below, a constant grip force (friction resistance) is obtained between the first wheel 20 as the driving wheel and the rail 1.

Now, as shown in FIG. 6B, when the passenger sits on the seat 16 arranged above the second wheel 3〇, the cushion 32 is elastically deformed due to the total weight of the vehicle and the passenger, and the cushioning member 32 is elastically deformed. (2) The vehicle takes an inclined position such that one end on the wheel side approaches the rail 1. At this time, the lever 1 or the seesaw motion with the first wheel 2 The end of the first wheel on the third wheel side moves in a direction away from the rail, that is, upwards. However, upward movement of the end of the base 11 on the third wheel side is hindered by the third wheel held by the frame 41 being pressed against the lower surface of the rail. The force pressing the third wheel against the rail acts in a direction to reduce the distance between the first wheel and the third wheel, so that the first wheel is also pressed against the rail. In this way, if the buffer 32 is elastically deformed and the vehicle takes an inclined posture, the rail grip force of the first wheel, which is the driving wheel, increases.

In the above description, the inclination posture of the vehicle is drawn relatively large so as to facilitate understanding of the present invention. In the present embodiment, since the first to third wheels are rubber tires, the inclination of the vehicle is obtained by elastic deformation of the rubber tires. However, when metal wheels are used instead of rubber tires, For example, if at least one of the first wheel and the third wheel is held on the base via a buffer such as a coil panel, the inclination posture of the vehicle can be obtained in the same manner as described above.

When the rail vehicle 10 travels along the inclined rail 1, for example, as shown in FIG. 7, the first wheel 20 becomes the front wheel when traveling uphill, and the second wheel 30 when traveling downhill. It can be a front wheel. In this case, the center of gravity of the vehicle moves toward the second wheel 30, so that a larger load is applied to the buffer 6, and the entire vehicle is more likely to take an inclined posture. As a result, a larger grip force can be generated between the first wheel 20 which is the driving wheel and the rail 1 in the inclined area of the rail than in the case of horizontal traveling. From this point of view, the distance between the first wheel and the center of gravity of the running vehicle is longer than the distance between the second wheel and the center of gravity, and longer than the distance between the third wheel and the center of gravity. Preferably, it is shortened. In short, the center of gravity of the running vehicle should be located near the second wheel. Further, the deformation 衋 of the buffer 32 increases in proportion to the weight of the vehicle (including the load). This means that the grip force of the first wheel 20, which is the driving wheel, can also be increased according to the vehicle weight. As described above, according to the present invention, if a buffer having a desired elastic deformability is employed, an appropriate gripper can be provided in accordance with a change in vehicle weight.

In the above-described rail traveling vehicle 1 た, one third wheel 40 is provided for each rail 1. However, if further improvement in grip force is required, the number of third wheels 40 is increased. You may shake it. For example, in Fig. 8, the rail vehicle 1〇 A pair of third wheels 40 is rotatably held at the end of the hanging frame 41 away from each other in the extending direction of the rail. That is, the pair of third wheels 4 〇 are rotatably held at both ends of the support member 43. The support member 43 is attached to the frame 41 using a pin 45 at its center, and the support member 41 can swing around the pin 45 as shown by an arrow in FIG. Thereby, even when the rail traveling vehicle 10 takes an inclined posture, all of the third wheels 40 can be stably brought into contact with the lower surface 1 b of the rail 1.

In such a configuration, when the buffering body 32 is elastically deformed by receiving the vehicle weight and the rail running vehicle 10 takes an inclined posture, the lever principle is used according to the principle of leverage as in the case of FIG. 6B. All of the wheels 40 can be pressed against the lower surface of the rail 1, and as a result, the grip force can be obtained by sandwiching the rail between the first wheel 2 〇 and the plurality of third wheels 40. Since the contact area between the third wheel and the rail is increased, the grip force of the rail is further increased as compared with the case of FIG. 6B.

In the embodiment described above, a rail traveling vehicle that can travel on a pair of rails 1 extending in parallel is described. However, a single rail, that is, a monorail traveling vehicle, has the same effect as the above embodiment. Needless to say, you can get

The rail traveling vehicle and the rail system according to the present invention have been described above based on preferred embodiments. However, these are for understanding the technical idea of the present invention, and have a meaning to limit the present invention. Should not be interpreted as In addition, the configuration of the present invention may be appropriately changed without departing from the technical idea of the present invention. Industrial applicability

As understood from the above embodiment, according to the present invention, in addition to the first wheel and the second wheel traveling on the upper surface of the rail, a third wheel traveling on the lower surface of the rail is provided, and the first wheel is mounted on the rail. In the extension direction of the vehicle, it is arranged between the second wheel and the third wheel, and the second wheel is held via the shock absorber. Therefore, when the shock absorber is elastically deformed and the whole vehicle inclines, the leverage According to principle (1), the third wheel is pressed against the lower surface of the rail, and as a result, the rail grip force of the first and third wheels increases. Since this grip force varies depending on the total weight of the vehicle, an expensive rail grip force control device must be used. It is possible to stably provide smooth running by preventing the driving wheel from slipping with a relatively simple configuration without introducing it inside the vehicle. Therefore, it is suitable not only for short-distance transport of passengers, but also for luggage transportation, and is expected to be used as an amusement vehicle or as a means of transportation in amusement parks such as Teshima Park.
