Definitions

• the present invention relates to a device for attaching an inner tire and an outer tire to a wheel tube, and in particular, two tires on both sides of one wheel hub. Concerning the mounting device of the adjacent double evening bar.
• the conventional tire mounting device has a locking portion 3 integrally formed on the outer peripheral portion of the inner plate 2 of the wheel hub 1, and the locking portion 3 is formed integrally with the wheel mounting device. 3 and the abutment 6 of the rim 5 of the inner tire 4 is brought into contact with the outer rim 9 of the wheel tire 1 and the rim 9 of the outer tire 8 is fitted to the outer plate 7 of the wheel hap 1. In this case, when a cylindrical spacer 10 is provided between the inner surface 9 a of the outer tire trim 9 and the outer surface 5 a of the inner tire trim 5.
• the inner distal end 12 a of the cylindrical holding member 12 is brought into contact with the locking receiving portion 11 of the outer tire 9, and the base end 12 of the holding member 12 is brought into contact therewith.
• the clamp 15 is brought into contact with the outer end face of b, and this clamp 15 is fastened to the reducer case 13 with bolts 14 so that the holding member 1 2
• the inner tip 1 2a to the outer tire 9 Receiving portion 1 1 Tires mounting apparatus to Let 's that put press on is that has been known, et al.
• the holding member 12 of the outer tire 9 is pressed by pressing the holding member 12 with the clamp 15.
• the clamp 15 is pressed against the lock 3, so if the clamping force of the clamp 15 is not increased, the lock receiver 6 of the inner tire 5 and the wheel hub 1 will not work.
• the locking portion 3 of the outer tire 9 and the locking receiving portion 11 of the outer tire 9 and the inner end portion 12a of the holding member 12 cannot be press-bonded, and the tightening torque is reduced.
• the present invention has been made in view of the above-mentioned circumstances in the prior art, and its purpose is to form it on the inner side of the wheel hub.
• the inner and outer tires can be securely pressed against the locking part and spacer with a smaller tightening force than in the prior art, and tightened.
• Provide a tire mounting device that can easily and easily perform tire mounting and dismounting work without the need for rework.
• the wheel hub and the wheel hub are respectively located inside and outside of the wheel hub.
• the inner and outer tire rims to be tightened, and a tube interposed between the rims and located on the outer peripheral side of the wheel hub.
• a tire mounting device having a shape-like spacer, wherein a lock receiving portion formed at an outer peripheral end of the inner tire is provided on an inner peripheral portion of the wheel hub. In order to press against the engaging portion formed on the surface portion, it comes into contact with the outer peripheral end surface of the inner tire and engages the inner plate of the wheel hub via a fastening means.
• a tire mounting device characterized by comprising an outer clamp which is locked to an outer plate of the wheel hub via a fastening means.
• the inner and outer tires are individually locked by the inner and outer clamps, respectively, these clamps are used.
• the tightening force for each of the bolts is weaker than the conventional tightening force, and there is no need for retightening work, so the mounting and dismounting work of the tires Has the effect of being extremely easy to perform.
• FIG. 1 is a schematic vertical sectional view showing a conventional tire mounting portion
• FIG. 2 is a schematic vertical sectional view showing one embodiment of the present invention.
• FIG. 3 is a view of the specific example shown in FIG. 2 as viewed from the arrow IE in FIG.
• FIG. 2 which is a schematic longitudinal section of a preferred embodiment of the present invention
• the basic structure is the same as that of the conventional example shown in FIG.
• Common elements are denoted by the same reference numerals, and descriptions thereof are omitted to avoid duplication.
• a speed reducer case 13 is integrally provided at the intermediate portion of the outer plate 7 of the wheel hub 1, and an outer peripheral portion 7a of the outer ⁇ 7 is formed as a thick portion. Then, a plurality of screw holes 16 are drilled in this area, bolts 17 are combined with these screw holes 16 and locked there, and 17 is fitted with the outer clamp 19, and then the outer force and the nut 18 are screwed together to tighten the outer clamp 19, and thus the presser foot The member 12 is pushed inward in the axial direction of the wheel hub 1.
• the outer peripheral part 2 a of the inner side ⁇ 2 of the wheel hub 1 is Then, a plurality of screw holes 2 2 are drilled in the circumferential direction, and bolts 21 are respectively screwed into these screw holes 20 to be locked there.
• the inner clamp 23 is fitted to the bolts 21, and the outer force and the nut 22 are further screwed into the inner clamp 23. So that the locking receiving portion 6 formed on the rim 5 of the inner tire 4 is pressed against the locking portion 3 of the wheel hub 1. is there .
• outer clamp 19 and the inner clamp 23 are arranged so as to be offset from each other in the circumferential direction as shown in Fig. 3.
• a notch 24 is formed at a portion of the outer circumferential portion 7a of the ⁇ 7 facing the inner clamp 23, and the inner clamp is formed by forming the notch 24.
• the nuts 22 for tightening or loosening the nuts 23 can be easily tightened or loosened.
