[0004]

[Problems to be solved by the device]

 However, in this type of roller tester, since it is necessary to cope with vehicles 1 having different tire sizes, conventionally, the stopper roller 9 is attached to one end of the link member 10 of the link mechanism. The contact position is adjusted.

However, in the case of the stopper device 8 having the conventional structure having such a function, many link mechanisms (for example, three sets of link mechanisms) are necessary, or at least the number of link mechanisms used is at least this link mechanism. There were problems in that many cylinders (for example, three cylinders) were required to drive the mechanism.

The present invention has been made in view of such a conventional situation, and is inexpensive, highly reliable in operation, and easy to use by combining one link mechanism and two cylinders. It is intended to provide an excellent roller tester stopper device.

[0007]

[Means for Solving the Problems]

 The feature of the present invention is that the stopper in the roller tester is designed to prevent the vehicle from falling by bringing the stopper roller into close proximity or contact with the tire of the vehicle placed on the test roller. In the device, a link mechanism to which the stopper roller is mounted, a first cylinder that drives the link mechanism to control a facing position or a contact position of the stopper roller with respect to a tire of the vehicle, and the entire link mechanism. And a second cylinder that controls the contact position or contact position of the stopper roller with respect to the tire of the vehicle by moving up and down.

[0008]

[Action]

 According to this stopper device, by driving the first cylinder and the second cylinder, the stopper roller can be opposed to or brought into contact with the optimum position of the tire according to any tire size. This effectively prevents the vehicle from falling off.

【Example】

 1 to 2 show respective operating states of an embodiment of the stopper device in the roller tester according to the present invention. In the drawing, a stopper device (only one side) of the rear tire portion in the roller tester as shown in FIG. 3 is shown. In these figures, 15A and 15B are small and large diameter rear tires of the test vehicle, 16 is a rear main test roller, 17 is a rear auxiliary test roller, and 18 is a stopper roller 19 for the rear tires 15A and 15B. , Is a stopper device that allows close proximity.

The stopper device 18 has a slide base 30 which is movable up and down on a base base 22 of a machine frame 21. A cylinder rod 41 of a second ascending / descending cylinder 40 fixed to the base table 22 side is connected to the slide table 30, and the slide table 30 is moved up and down by driving the cylinder 40. .. At this time, a guide shaft 31 is planted downward on the slide base 30 side so that the slide base 30 can be lifted and lowered stably, and is guided to the machine frame 21 side. There is.

A horizontal member 33 supported by front and rear standing members 32, 32, etc. is assembled on the slide base 30. The horizontal member 33 has a long hole extending to the right in the drawing in the horizontal direction. The guide hole 33a is formed. The stopper roller 19 is attached to the tip of the guide hole 33a, and the protruding portion at the lower right end of the floating link member 51, which also serves as a roller support member, of the link mechanism 50 for moving the stopper roller 19 in position in the figure. A shaft pin (a shaft rod or the like is possible) 52 provided on the is fitted.

The floating link member 51 forms a pair with a fixed link member 54 pivotally mounted on a table portion 53 of the slide table 30 on the left side in the figure. The free end side of the fixed link member 54 is The projecting portion 51a provided below the tip of the member 51 is pivotally attached together. Further, the cylinder rod 61 of the first cylinder 60 that drives the link mechanism 50 is axially attached to the axial attachment portion of each of the link members 51 and 54. Further, the other end of the first cylinder 60 (the side opposite to the cylinder rod 61) is pivotally attached to a standing piece 34 or the like installed on the right side of the slide base 30 in the drawing.

Therefore, in the case of the link mechanism 50, when the cylinder rod 61 of the first cylinder 60 is contracted, the free end side of the fixed link member 54 is pulled clockwise in the drawing, and Since the shaft pin 52 of the floating link member 51 has moved to the right end side of the guide hole 33a of the horizontal member 33 in the figure, the floating link member 51 is in a substantially horizontal state, and the stopper roller 19 becomes the roller tester. It is stored and held under the floor surface F in the test site where the When the cylinder rod 61 of the first cylinder 60 is extended from this state, the free end side of the fixed link member 54 rises in the upward counterclockwise direction in the figure as the rod 61 extends, and the floating link member 54 also rises. Since the shaft pin 52 of 51 moves to the left end side of the guide hole 33a of the horizontal member 33 in the figure, the free end side of the floating link member 51 moves to the upper left side in the figure in conjunction with the cylinder 60. The stopper roller 19 is held so as to protrude from the floor surface F.

Next, the operation of the stopper device 18 of the present invention thus configured, particularly the operation when the tire sizes are different, will be described. For example, as shown in FIG. 1, when the tire of the test vehicle is a small-diameter rear tire 15A (solid line), the cylinder rod 41 of the second cylinder 40 is contracted, and the slide table 30 is moved to the base table 22. The cylinder rod 61 of the first cylinder 60 is extended and the link mechanism 50 is driven in the state where the link mechanism 50 is placed thereon. Then, as described above, the free end side of the floating link member 51 protrudes from the floor surface F, and the stopper roller 19 is positioned behind the rear tire 15A and higher than the rear auxiliary test roller 17 as shown in FIG. Close to each other. This effectively prevents the small-diameter rear tire 15A from falling off. Of course, although not shown, such restrictions are also applied to the front tire.

On the other hand, as shown in FIG. 2, when the tire of the test vehicle is the large-diameter rear tire 15B (solid line), the cylinder rod 61 of the first cylinder 60 is contracted to cause the floating link member to contract. From the state where 51 is in a substantially horizontal state, the cylinder rod 41 of the second cylinder 40 is extended, and the slide base 30 is directly pushed up as it is, and the stopper of the floating link member 51 in a horizontal state. The roller 19 is brought closer to the rear of the rear tire 15B and at a position higher than that of the small diameter tire. This effectively prevents the large-diameter rear tire 15B from falling off. Of course, although not shown, such restrictions are also applied to the front tire.

In the above embodiment, the stopper roller 19 is made to face the tires 15A and 15B in close proximity, but the present invention is not limited to this close proximity, and may be directly contacted. Good. In the case of the running test, it is preferable that the stopper roller 19 be contactlessly contacted, but in the case of the roller, even if it is brought into direct contact with the roller, it smoothly rotates, so there is not much problem. Further, in the above-mentioned embodiment, the tire size is of two types, large and small, but the present invention is not limited to this. Further, not only when the cylinders 40 and 60 are driven separately, but also when they are driven simultaneously, it is possible to obtain a subtle confrontation and a contact position of the stopper roller 19.
