Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an inspection device for inspecting the engine performance, brake performance, etc. of a completed motorcycle.

(Prior art) The applicant of this application previously developed a device of this type in the
According to No. 60-184399, a front wheel inspection section having a rotating drum on which the front wheel of a motorcycle is placed and a rear wheel inspection section having a rotating drum on which the rear wheel is placed are arranged side by side, and the front wheel and rear wheel are rotated at the same time. Furthermore, the rear wheel inspection section is equipped with a groove wheel that sandwiches the rear wheel from the front and back, and the groove wall of the groove wheel supports the rear wheel from the side to prevent the motorcycle from falling over. suggested something.

(Problems to be solved by the invention) In the above-mentioned method, the side surface of the rear tire is rubbed by the groove wall of the groove wheel, which creates unnecessary resistance on the rear wheel and furthermore causes scratches on the tire. In addition, the front wheels could swing from side to side, or the handle could be taken off and fall over, creating problems that required skill to operate.

An object of the present invention is to provide a device that solves these problems.

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a front wheel inspection section having a rotating drum on which the front wheel of a motorcycle is placed, and a rear wheel inspection section having a rotating drum on which the rear wheel is placed. In an inspection device arranged in parallel in the front and rear, guide rollers that sandwich the front wheel from both sides with a small clearance are provided on both sides of the upper part of the front wheel inspection section so as to be movable laterally. The present invention is characterized in that at least two sets are provided, a front set that holds the rear part of the front wheels, and a rear set that holds the rear part of the front wheels, and the arrangement heights of the guide rollers of the two sets are made different from each other.

(Function) An operator rides the motorcycle and performs the inspection with the front and rear wheels placed on the rotating rollers of the front wheel inspection section and the rotating rollers of the rear wheel inspection section. Since it is held between guide rollers from both sides, it is prevented from swinging from side to side, and it is reliably prevented from falling over due to the handle being taken off.

In addition, the guide rollers sandwich the front wheels with a small clearance, so when the front wheels do not swing, the front wheels do not come into contact with the guide rollers, and unnecessary resistance is not applied to the front wheels. When this comes into contact with the guide roller, the roller rotates and the front tires are not scratched.

By the way, when considering ensuring balance in a motorcycle, simply placing one set of guide rollers on both sides of a portion of the front wheel will not effectively prevent the front wheel from moving straight in the direction of the steering wheel due to steering wheel shake. Therefore, it is desirable to arrange at least two sets of guide rollers on both sides of the front and both sides of the rear of the front wheel. However, if the two sets of guide rollers are arranged at the same height, it will be difficult to prevent the front wheel from falling. This is particularly noticeable when each part of the front wheel is sandwiched between each set of guide rollers with a certain clearance.

In this case, if the heights of the front set of guide rollers that sandwich the front part of the front wheels and the rear set of guide rollers that sandwich the rear part of the front wheels are arranged at different heights, the vertical direction can be controlled by the two sets of guide rollers. Since the front wheel can be supported by the span, it is possible to effectively prevent the front wheel from falling over.

Therefore, in the present invention, at least two sets of guide rollers are provided, a front set that holds the front part of the front wheel, and a rear set that holds the rear part of the front wheel, so that the guide rollers move in the direction of the steering wheel turning angle from the straight-ahead state of the front wheels. In addition to preventing the front wheel from wobbling, the guide rollers on both sides are arranged at different heights to prevent the front wheel from tipping over.

(Embodiment) In the drawings, 1 indicates a front wheel inspection section, and 2 indicates a rear wheel inspection section arranged in parallel behind it, and each pair of front wheels a and rear wheels b of a motorcycle are mounted on each of the inspection sections 1 and 2. A rotating drum 3, 3, and an elevating plate 4 positioned between the two drums 3, 3 and raised and lowered by a cylinder 4a are provided, and each elevating plate 4 is raised to the same level as the floor surface 5. Enter the motorcycle from the rear, place the front wheel a and the rear wheel b on the respective elevating plates 4, and then lower the elevating plates 4 to move the front wheel a and the rear wheel b into each pair. Rotating drum 3,
I made it support 3. Furthermore, the front rotating drum 3 of the front wheel inspection section 1 and the front rotation drum 3 of the rear wheel inspection section 2 are interlocked via the bevel gear mechanism 6 and the synchronization shaft 7, so that when the rear wheel b is driven, the front wheel a In order to prevent the two-wheeled vehicle from flying out, a pair of front and rear stopper arms 8, 8 each having a roller 8a at the tip that clamps the rear wheel b from the front and rear are installed in the rear wheel inspection section 2, respectively, to prevent the two-wheeled vehicle from flying out. It was set up so that it could rise and fall freely.

Furthermore, side rollers 9 are installed on the lifting plate 4 of the rear wheel inspection section 2 to serve as rough guides in the lateral direction for the front and rear wheels a and b when entering the vehicle.

Here, the front wheel inspection section 1 is provided with guide rollers 10 which are movable laterally and which sandwich the front wheel a from both sides with a small clearance (for example, 5 to 10 mm) on both sides of the upper part thereof. In more detail, rotating drums 3, 3 are placed on the floor 5 of the inspection section 1.
A pair of movable frames 11, 11 are provided on both sides of the arrangement part, and are moved forward and backward from an outer open position to an inner closed position by cylinders 11a, respectively. Three guide rollers 10 are installed as shafts, facing each other on the lower side and the rear side.
When both movable frames 11, 11 are advanced to the closed position, the front wheel a is held between the guide rollers 10, 10 at the front, lower part, and rear with a small clearance.

The pair of left and right guide rollers 10 in the front position that sandwich the front part of the front wheel a are positioned relatively upward, and the pair of left and right guide rollers 10 in the rear position that sandwich the rear part of the front wheel a are positioned relatively downward. As explained in the section of the above-mentioned function, the function of preventing the front wheel a from falling over has been improved.

According to this, the left and right swing of the front wheel a is regulated, and it is reliably prevented from falling over due to the steering wheel being taken off. Also, unless the front wheel a swings, the front wheel a does not come into contact with the guide roller 10, and the front wheel a Unlike the case where wheel a is constantly clamped from both sides, unnecessary resistance is not applied to front wheel a, and when front wheel a comes into contact with guide roller 10 due to its deflection, roller 10 prevents the rotation of front wheel a. Since the front wheel a also rotates, there will be no scratches on the front tire a.

(Effects of the invention) As described above, according to the invention, the left and right swing of the front wheels is controlled, and even non-skilled workers can easily carry out work without worrying about the steering wheel falling off or falling over.
Furthermore, it has the effect of preventing unnecessary resistance from being applied to the front wheels or from being scratched.
