DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle guide device for positioning a vehicle in a predetermined position by passing the vehicle over an upper surface, and more particularly, to a vehicle guide for accurately and stably positioning the vehicle in a predetermined position. Related to the device.

[0002]

2. Description of the Related Art In an apparatus for performing measurements or the like with a vehicle mounted thereon, it is important that the vehicle enters the apparatus in a predetermined posture. For example, in a wheel alignment measurement device that mounts a vehicle on the device and measures the alignment of each wheel, if the vehicle enters the device obliquely, the measurement value may be inaccurate. Of course, the device itself is provided with a mechanism for correcting the attitude of the vehicle, but it is desirable that the correction amount is small. Therefore, a part of the guide member that allows the vehicle to enter the wheel alignment measurement device,
A vehicle guide device for allowing the vehicle to enter in a predetermined posture is provided.

FIGS. 5 to 7 show an example of a vehicle guidance device.
As shown in FIG. 5, the vehicle guide device 1 includes a pair of truncated cones 4 disposed on the upper surface 3 continuous with the slope 2 and separated by a tire width, and a roller 5 disposed between the cones 4. Have been. The roller 5 has an axial direction defined as the vehicle traveling direction, and rotates the tire to move the tire in a direction perpendicular to the vehicle traveling direction.

[0004] Therefore, when the tire 6 of the vehicle that has moved up the slope 2 is displaced from a predetermined position (between the cones 4), the tire 6 rides on the slope of the cone 4 and slides down from the slope, thereby causing the upper surface 3 between the cones 4 to slide. (See FIG. 6). At this time, when the tire 6 rests on the roller 5, the roller 5 rotates to slide the tire 6 between the pair of cones 4. Thus, the tire 6
Is guided to a predetermined position, whereby the vehicle can enter a device, for example, a wheel alignment measuring device in a predetermined posture.

[0005]

However, as shown in FIG. 7, when the tire 6 is slid by the roller 5, the tire 6 is deformed along the outer periphery of the roller 5 by the load of the vehicle. As a result, the tire 6 comes into contact with the upper surface 3 on both sides of the roller 5 and hinders the rotation of the roller 5. Therefore, there is a possibility that the tire 6 does not always move to the predetermined position. In other words, there is a possibility that the tire 6 passes between the cones 4 while a part of the tires 6 rides on the slopes of the cones 4, and the vehicle may not be in a predetermined posture.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-described problem, and has as its object to provide a vehicle guidance apparatus for smoothly and surely bringing a vehicle into a predetermined posture.

[0007]

According to a first aspect of the present invention, there is provided a vehicle guide device for positioning a vehicle in a predetermined posture by passing the vehicle through the upper surface. A pair of guide members, which are arranged in parallel at a tire width interval, and a pair of guide members through which the tire passes, and a rotating shaft that is closer to the vehicle entry side of the guide members on the upper surface so as to approach each other in the vehicle traveling direction. A pair of rotatable guide rollers that are installed in a diagonal direction and guide the tire between a pair of guide members, and a tire that abuts on the guide rollers are placed on the upper surface and moved in a direction perpendicular to the vehicle traveling direction. A movable plate.

The operation of the first aspect of the present invention will be described.

In the vehicle guide device according to the present invention, when the vehicle enters a position different from the predetermined position, the tire of the vehicle comes into contact with the guide roller. The guide roller rotates in the direction opposite to the tire rotation direction due to the contact of the tire, and prevents the tire from riding on the guide roller. On the other hand, a reaction force acts on the tire in a direction orthogonal to the vehicle traveling direction from a guide roller whose rotation axis is arranged obliquely to the vehicle traveling direction. As a result, the tire mounted on the moving plate moves in the direction perpendicular to the vehicle traveling direction together with the moving plate, and moves on the moving plate in the vehicle traveling direction by the rotation of the tire. That is, the tire moves obliquely forward in the vehicle traveling direction while abutting on the guide roller, and enters between a pair of guide members disposed on the vehicle traveling direction side of the guide roller. Since the pair of guide members are arranged in parallel with the width of the tire, the vehicle is brought into a predetermined posture when the tire passes between the guide members. That is, the vehicle in a predetermined posture can enter, for example, straight into the wheel alignment measuring device.

According to a second aspect of the present invention, in the first aspect, the moving plate includes a rolling member at a lower portion thereof,
The rolling member moves by rolling.

The operation of the second aspect of the present invention will be described.

The moving plate is moved by rolling a rolling member provided at a lower portion. Therefore, even if the weight of the vehicle body acts on the moving plate via the tire, the moving plate can move smoothly because the rolling friction resistance is lower than the sliding friction resistance.

[0013] The invention according to claim 3 is the invention according to claim 1 or 2.
In the invention described in the above, the movable plate moves inside a concave portion provided on the upper surface, and a rotatable guide roller that is in contact with an end surface of the movable plate is provided on a vehicle entry side of the concave portion. It is characterized by.

The operation of the third aspect of the present invention will be described.

The movable plate moving inside the concave portion is pressed against the vehicle entry side of the concave portion by the rotation of the tire on the movable plate, but the end surface of the movable plate is abutted (supported) by the guide roller. Therefore, it can be moved smoothly by the rotation of the guide roller.

According to a fourth aspect of the present invention, in the first aspect of the invention, there is provided an adjusting device for adjusting a distance between the guide members in accordance with a width of the tire. I do.

The operation of the invention according to claim 4 will be described.

Since the guide member can be moved in the direction orthogonal to the vehicle traveling direction by the adjusting means, the distance between the guide members can be changed in accordance with the size of the tire.
The vehicle can be accurately set to a predetermined posture. Further, even in the case where the interval between the tires differs depending on the type of the vehicle, the position of the guide member can be changed by moving the guide member in the direction perpendicular to the direction of the tire.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A vehicle guidance device according to one embodiment of the present invention will be described with reference to FIGS.

As shown in FIG. 2, the vehicle guidance device 10
Used integrally with the slope member 12. The slope member 12 includes an inclined surface 14 that guides the vehicle to the upper surface of the vehicle guide device 10 and a pair of guide pipes 16 that guide the tire in a predetermined direction. The pair of guide pipes 16 are arranged on the inclined surface 14 at intervals sufficiently larger than the width of the tire, so that a vehicle (tire) can easily enter between the guide pipes 16.

As shown in FIG. 1, the vehicle guidance device 10
It is a rectangular body having an upper surface 18 that is continuous with the inclined surface 14 of the slope member 12. A pair of pipe members 20 for guiding the tire to a predetermined position and a slide plate 22 for moving the tire in a direction perpendicular to the vehicle traveling direction are provided on the upper surface 18.
Are arranged.

The pair of pipe members 20 are shown in FIGS.
As shown in the figure, guide pipes 2 arranged in parallel with each other
4 and a guide roller 26 that is arranged obliquely in a direction continuous with the guide pipe 24 and separated from each other. Each pipe member 20 is separated from the upper surface 18 and the slide plate 22 by inserting two pipes 30 into the positioning holes 28 formed in the upper surface 18 and bringing the support roller 32 into contact with the slide plate 22. It is arranged in a state.

As shown in FIG. 3, three positioning holes 28 are formed on the upper surface 18 at a predetermined pitch in a direction perpendicular to the vehicle traveling direction (arrow Y direction, hereinafter referred to as Y direction). Three are formed at positions shifted in the X direction (hereinafter, referred to as the X direction) with a half pitch shift. Therefore, by inserting the pipe 30 into any of the positioning holes 28, the position in the Y direction can be adjusted at half pitch intervals.

Therefore, the pair of pipe members 20 can change the positioning hole 28 into which the pipe 30 is inserted according to the size of the tire, and can change the interval between the guide pipes 24. In addition, even when the distance between the tires of the two wheels is different due to the difference of the vehicle type, the position of the pipe member 20 in the Y direction can be changed to cope with it.

The end of the pipe member 20 in the direction of the arrow X1 (hereinafter referred to as the X1 direction) is supported by the support roller 32 contacting the slide plate 22. Therefore, when the slide plate 22 slides in the Y direction as described later, the support roller 32 rotates on the slide plate 22 and does not hinder the slide of the slide plate 22.

The slide plate 22 is disposed in a rectangular recess 34 formed on the upper surface 18.
Is narrower than the width in the Y direction. Also, the recess 34
As shown in FIG. 4, a plurality of grooves 44 extending in the Y direction are formed on the slide plate 2.
A plurality of steel balls 36 arranged in a retainer 46 arranged at the lower part of the second 2 have entered. Therefore, the slide plate 22 moves in the Y direction by the retainer 46 (steel ball 36) guided in the groove 44 moving in the Y direction.

Further, the slide plate 22 is arranged from the vicinity of the portion in contact with the inclined surface 14 in the X direction to the lower part of the guide roller 26 and the end of the guide pipe 24 in the X1 direction. This is because the tires
Until it enters between the guide pipes 24
This is to ensure that the tire is placed on the slide plate 22.

A notch 38 is formed at each of two locations on the X-direction side surface of the concave portion 34, and a guide roller 40 is disposed in each of the notches 38. Guide roller 40
A part of the outer peripheral surface protrudes from the notch 38 into the concave portion 34 and is in contact with the end surface of the slide plate 22. Therefore, when the slide plate 22 slides in the Y direction, the rotation of the tire causes the slide plate 22 to slide.
Is prevented from being pressed against the side surface of the concave portion 34, and the slide plate 22 is reliably slid by the rotation of the guide roller 40.

The operation of the thus configured vehicle guidance device 10 will be described.

In advance, a pipe 30 is inserted into a hole 28 at a predetermined position corresponding to the tire width of the vehicle, and a guide pipe 24 is inserted.
Is adjusted, and the slide plate 22 is arranged at the center in the Y direction in the concave portion 34.

First, both wheels of the vehicle are connected to a pair of slope members 1.
2 and is raised along the inside of the pair of guide pipes 16. At this time, the interval between the pair of guide pipes 16 is sufficiently larger than the width of the tire, so that the approach is easy.

When the vehicle climbs up the inclined surface 14, the tire 42 reaches the upper surface 18 of the vehicle guide device 10 and is placed on the slide plate 22. here,
When the tire 42 is displaced from a predetermined position (the tire 42 does not enter straight between the pair of guide pipes 24),
For example, in the case shown by solid lines in FIGS. 3 and 4, the tire 42 comes into contact with the guide roller 26. When the tire 42 contacts the guide roller 26, the guide roller 2
6 rotates in the direction of arrow A opposite to the tire rotation direction, and prevents the tire 42 from riding on the guide roller 26.

On the other hand, the tire 42 abutting on the guide roller 26 receives a reaction force from the guide roller 26 toward the center (Y1 direction), and the friction of the slide plate 22 by friction.
To transmit the reaction force. Slide plate 22
The steel ball 36 (retainer 46) rolls (moves) in the groove 44 so that the tire 4
2 and move smoothly in the Y1 direction. At this time, a force in the X1 direction is applied to the slide plate 22 by the rotation of the tire 42. However, since the guide roller 40 supports the end surface of the slide plate 22 in the X1 direction, the slide roller 22 smoothly moves in the Y1 direction.
Can move in any direction.

Therefore, by the rotation of the tire 42 (movement in the X2 direction) and the movement of the slide plate 22 in the Y1 direction, the tire 42 is kept in contact with the guide roller 26 as shown in FIG. It moves diagonally forward (arrow B direction) with respect to (X direction).

The tire 4 has moved to a substantially central position in the Y direction.
2 is guided between a pair of guide pipes 24 spaced apart from each other by a distance corresponding to the tire width by being separated from the guide roller 26 (see FIGS. 3 and 4, a tire 42 indicated by a two-dot chain line).
reference). When the tire 42 enters between the pair of guide pipes 24, the tire 42 advances straight in the X2 direction.

As a result, the vehicle can enter the measuring device in a predetermined posture (straight in the X2 direction).

As described above, in the vehicle guide device 10 according to the present embodiment, the guide roller 26 for guiding the tire 42 to a predetermined position is rotatable.
The slide plate 22 smoothly and reliably guides the tire 42 between the pair of guide pipes 24 without riding on the tires 6.

In particular, when the tire 42 moves in the Y direction, the slide plate 22 on which the tire 42 is mounted moves in the Y direction via the steel ball 36 (retainer 46) instead of moving the tire 42. Therefore, the tire 42 can be smoothly moved without being affected by the deformation of the tire 42 due to the weight of the vehicle body.

The pipe member 20 is provided in a proper one of the plurality of holes 28 formed in the upper surface 18.
Is inserted, the interval between the guide pipes 24 can be adjusted according to the size of the tire 42 or the interval between the tires 42. Therefore, regardless of the tire size and the vehicle type, the vehicle can be accurately set to the predetermined posture (guided in the predetermined direction).

Further, when the slide plate 22 slides in the Y direction, the support roller 32 supporting the pipe member 20 rotates on the slide plate 22, so that the movement of the slide plate 22 is not hindered.

Further, since notches 38 are formed at both ends in the X direction of the concave portion 34 and guide rollers 40 are disposed inside, the slide plate 22 is pressed against the X direction wall surface of the concave portion 34 by rotation of the tire 42 or the like. The slide plate 22 is prevented from moving in the Y direction.

[0042]

In the vehicle guide device according to the present invention, the guide roller is rotated in the direction opposite to the tire rotation direction, thereby preventing the tire from riding over the guide roller, and the tire being guided by the guide roller is prevented from rotating. Since it is moved by the moving plate, it moves smoothly without being affected by deformation of the tire or the like. As a result, the tire can reliably enter between the pair of guide members, and the vehicle can be brought into a predetermined posture. As described above, the vehicle can be smoothly and reliably set to the predetermined posture.

In particular, since the moving plate is moved by the rolling of the rolling member, the moving plate can be moved smoothly. further,
Even if the moving plate is pressed to the vehicle approach side by the rotation of the tire, the guide roller abuts the moving plate,
The moving plate can be moved more smoothly by the rotation of the guide roller.

By providing the adjusting means, the position of the guide member can be adjusted according to the tire width and the tire interval, so that the vehicle can be accurately set to a predetermined posture regardless of the tire size and the vehicle type.
