Abstract

PROBLEM TO BE SOLVED: To self-travel on a superhighway by forming a stopper part rising from a bottom surface part in a hollow part, and forming a hollow part inside surface and a stopper as a noncontact structure under a static load of a machine body. SOLUTION: It is desirable that a stopper 7, side surface parts 3 and 4 to constitute a hollow part 6 and an inside surface of an outside surface part 5 do not contact with each other under a static load. On the other hand, when a load not less than that is applied, since these inside surface and stopper 7 contact with each other, a spring constant is suddenly increased. Therefore, at load time, the stopper 7 and an inside surface of the hollow part 6 collide with each other, and an effect of checking abnormal displacement of a segment (s) is exhibited. Therefore, it is necessary to sufficiently keep strength of the stopper 7 contacting with the inside surface of the hollow part 6. Therefore, it is desirable that a supporter 10 be embedded in the stopper 7. That is, the supporter 10 is welded to a plate 8, and strength of the stopper 7 is secured by this supporter 10.

2. Description of the Related Art The structure of a wheel in which hollow segments are continuously mounted on a rim serving as a base of a vehicle wheel by bolts, nuts, or the like is known. For example, Tokuhyo Hei 4-500485
However, each segment forms a hollow portion in the width direction of the wheel, and the side portions constituting the hollow portion support each other, and the vibration during operation is reduced due to the deformation of the side portion. The structure is relaxed.

[0003] However, the supporting force due to the contact between the side portions of the segments mounted on the wheels is relatively small. Therefore, when a large load is applied during the work, the deformation (strain) of the side portions may not increase. Inevitably, the stability was poor. Further, since the side portions of the segments are always in contact with each other, for example, when subjected to high-speed running, frictional heat is generated due to friction between the side portions of the segments, and the segments are melted or smoked, and the life is short. There were drawbacks. According to our test, as a result of running test at 50 km / h, smoke was generated in 9 minutes, and the side part was melted and destroyed.

Due to the presence of this support, the spring constant of the stopper is increased, and the amount of strain of the segment can be reduced when the inner surface of the hollow portion contacts the stopper. And, more preferably, the side surface portion of the adjacent rubber elastic body segment does not contact in the state where the segment is mounted on the wheel or the endless track zone, and the side surface portion of the rubber elastic body segment faces toward the stopper-direction. A structure having a curved surface is preferable. By adopting a structure in which the side surfaces of adjacent rubber elastic segments do not contact,
Since the side surface is not rubbed when traveling at high speed, the rubber is not melted or smoke is generated. Also, if the side surface of the rubber elastic body segment has a curved surface in the direction of the stopper, the amount of displacement can be scheduled in a certain direction, and a desired deflection can be obtained in advance, and the static load can be further improved. The stopper does not come into contact with the inner surface of the hollow part when traveling down or at high speeds. There is an advantage that the sway of such as is settled early.

DETAILED DESCRIPTION OF THE INVENTION As described above, the present invention makes the elasticity of the rubber elastic member hollow so as to soften the vertical spring characteristics during high-speed running to improve the riding comfort, and particularly to get over the protrusions on the running surface. The impact at the time can be reduced. In this case, it is preferable that the side surface portion and the outer surface portion constituting the segment hollow portion, that is, the inner surface of the grounding portion, do not contact the stopper formed in the hollow portion under a static load, but it generates heat during use. It is acceptable to make contact so that smoke is not emitted. Here, “under static load” means a load applied to the segment only by the weight of the machine body when the machine body is stationary, and excludes a complicated load during work such as excavation.

Are formed of the same quality. Incidentally, the stopper provided in the hollow portion may, of course, expose the whole or a part of the supporter described later. on the other hand,
When the operation is stopped, the inner surface of the hollow portion of the segment comes into contact with the stopper due to the degree of load applied, thereby increasing the spring constant and reducing the amount of distortion of the segment. By continuing these contacts, a loss occurs due to friction between the stopper and the side surface portion and the outer surface portion of the hollow portion, thereby providing a damping effect, for example, when a large load is input during excavation work or the like. On the other hand, shaking such as pitching of the fuselage is settled early. Needless to say, a constant lug can be formed on the outer surface of the segment S.
