Each of these rollers 15 is a roller for interlocking with a sensor (not shown) for detecting the position of the vehicle to make forward and reverse rotations in the same direction at the same time to finally correct the entry position of the vehicle. The turntable 1 is not limited to the above, and various known turntables may be used.

<C> Guidance device An opening is provided on the road surface on the entrance side of the turntable 1,
The guidance device 2 is housed in this opening at the same level as the road surface. The guide device 2 is composed of a rocking frame 21 having rigidity that is inclined in the left-right direction with respect to the approach direction of the vehicle, and a plurality of correction rollers 22 arranged on the rocking frame 21. The swing frame 21 has a long side 2
1a and a short side 21b, a support shaft 23 projecting at a midpoint of each long side 21a is rotatably supported, and is configured to be swingable around a shaft support point. The guiding device 2 includes means for detecting tilting of the swing frame 21, and driving means for rotating all the correction rollers 22 in a specific direction based on the tilt sensing signal. In the present embodiment, a case where sensors 24 and 25 such as limit switches are attached to the lower surfaces of both sides of the swing frame 21 as swing sensing means of the swing frame 21 as shown in FIG. The tilt of the swing frame 21 may be detected from the non-contact method or the rotation amount of the support shaft 23. The spring 26 is disposed between the sides and the floor surface of the swing frame 21. The spring 26 is a member for preventing the rocking frame 21 from easily tilting due to a small eccentric load difference and for coping with vehicle models having different weights.
Fixed roller 22 is disposed parallel to the approach direction of the vehicle, and is configured to rotate in unison in a specific direction when the tilting of the oscillating frame 2 1 is sensed. FIG. 4 shows the rotational force of the motor 4 .
All corrections are made by using the bevel gear group 41 and the transmission shaft 42.
It is configured to transmit the rotation in a specific direction to the roller 22.
An example of driving the correction roller 22 is shown. Alternatively, the rotation of the motor 4 may be transmitted to each correction roller 22 by a chain.
When one of the sensors 24 and 25 senses the tilt of the rocking frame 21, each correction roller 22 rotates in a direction that balances the unbalanced load applied to the rocking frame 21, and the two sensors 24 and 25 are
It is configured to stop the rotation sensing Shinano Kunar tilting of the oscillating frame 21. That is, in FIG.
When tilting is detected on the 4th side, the pair of left and right tires A, A is fed in the direction of laterally feeding to the other sensor 25 side.
Is rotated, and when tilt is detected on the sensor 25 side, the rotation of the correction roller 22 is controlled in a direction of laterally feeding the tires A, A to the sensor 24 side. Further, the correction roller 22 may be configured such that a timer is incorporated in the drive circuit so that when the tilt of the swing frame 21 is detected, the correction roller 22 rotates for a fixed time and stops rotating.

Next, the operation of the guiding device will be described.

<A> Riding in a tire In FIG. 1, when a vehicle is driven into the turntable 1 by the driver's steering, the vehicle enters from the center line 3 of the turntable 1 in the direction of arrow B toward the guide device 2. Even if it comes, the vehicle entry direction is automatically corrected by the steps described below. That is, when the vehicle continues to move forward slowly, the pair of tires A, A forming the front and rear passes on the guiding device 2 before the turntable 1 is loaded.

<B> Tilting of the rocking frame Generally, the vehicle is designed so that the left and right weights are equal in consideration of the balance of the ground contact force of the tires. for that reason,
When the vehicle deviates from the center of the guiding device 2 as shown in FIG. 5, the weight of the vehicle acts on the swing frame 21 as an unbalanced load. Then, the guide frame 21 starts to tilt around the support shaft 23.

<C> Tilt Detection When the rocking frame 21 tilts a certain amount or more while the spring 26 contracts, the sensor 25 detects the tilt. All modifications roller 2 2 starts to rotate in unison on the basis of a sensing signal of the sensor 25, regardless of whether or not the tire A of the steering to the transverse feed is forced to the other sensor 24 direction A.

[0013] <D> pair of tires A by the rotation of the horizontal retrace modified roller 2 2 of the swing frame, when A is traversing, the tire A, the center of gravity between A approaches the center of the swinging frame 21, the tilting The oscillating frame 21 that had been returned is returned almost horizontally. The oscillating frame 21 is restored horizontally, the tilt sensing signal from the sensor 25 is released, the rotation of the correction roller 2 2 group is stopped. If the tire A by modifying the roller 2 2 group, even if A is excessively transverse feed, the other sensor 24 senses the tilt of the rocking frame 21, similarly to correct the mounting position of the tire. In this way, the tire A passing over the guiding device 2,
A is the left and right tires A, the midpoint of A is the center of the guidance device 2,
That is, the placement position is automatically corrected so as to substantially coincide with the center line 3 of the turntable 1. The correction operation of the mounting positions of the tires A and A is similarly performed for the rear wheels. Therefore, the vehicle can enter the turntable 1 with the center of the vehicle substantially aligned with the center line of the turntable 1.

[0014]

Since the present invention is as described above, the following effects can be obtained. <B> Until now, the driver's steering ability was used to get on the turntable. In the present invention, the riding position of the tire immediately before getting into the turntable can be automatically corrected by the guiding device so as to coincide with substantially the center of the turntable. Therefore, anyone can get on the turntable regardless of the steering ability of the driver, which can reduce the psychological burden on the driver and improve the safety of the entry steering. <B> It can be applied to various known turntables. <C> The structure is simple and the failure rate is extremely low.
