[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wheel mounting device.

[0002]

[Problems to be solved by conventional techniques and devices]

 When using a single-tire-equipped vehicle such as a passenger car, for example, a light four-wheel type luggage vehicle, when carrying luggage in the field, it may not be possible to drive with a single tire.In such a case, use a single tire with a double tire. Need to change to. At the time of this change, it is necessary to further attach the wheels to the wheels mounted on the axle. In this case, if the offset amount of both wheels is small, the side wall parts of the tires attached to both wheels will contact each other, and it will not be possible to further attach the wheels to the wheels attached to the axle. There's a problem.

Therefore, as shown in FIGS. 4 and 5, it is conceivable to use wheels 25 and 26 having a large offset amount L2. In this way, the sidewalls of the tires mounted on both wheels 25 and 26 do not come into contact with each other, so that the disc 29 of both wheels 25 and 26 is attached to the outer plate 28 of the brake drum 27 of the vehicle by the bolts 30, It can be attached with nuts 31 and 32. However, in the above case, the position of the inner wheel 25 moves to the inner side of the vehicle body more than in the case where the single tire is attached. There was a fear that the car would interfere with the car body, and there was a demand for a proposal that could solve this problem. An object of the present invention is to provide a wheel mounting device that can solve the above problems.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, a feature of the present invention resides in that a wheel mounted on an axle is further mounted with a wheel, in which both ends of the wheel are taperedly coupled to the discs of both wheels. That is, three or more spacers for keeping the distance between both wheels at a predetermined distance are arranged at equal intervals in the circumferential direction, and a means for fastening the discs of both wheels via a spacer is provided.

[0005]

[Action]

 When the double tire is installed, the offset amount of both wheels has been reduced, so that the position of the inner wheels does not move much more inward of the vehicle than when the single tire is installed, and the vehicle body is significantly moved. Even without modification, the tires mounted on the inner wheels are not likely to interfere with the vehicle body, and the spacing between the inner and outer wheels is made wider by the spacer. There is no fear that the departments will contact each other.

【Example】

 Hereinafter, a first embodiment of the present invention will be described with reference to the drawings of FIGS. 1 and 2. FIG. 1 shows a state in which a single tire is changed to a double tire in a vehicle equipped with a single tire (however, the tire is omitted. 1), 1 is an axle, 2 is a brake drum, which is arranged at the outer end of the axle 1. As shown in FIG. 2, the outer plate 3 of the brake drum 2 is formed with three or more mounting holes 4 at equal intervals in the circumferential direction.

Reference numerals 6 and 7 are a pair of inner and outer wheels, and both wheels 6 and 7 are composed of a disk 8 and a rim 9 on which a tire is detachably mounted. The outer peripheral portion of the disc 8 is fixed to the inner surface of the rim 9, the disc 8 is located inside one side portion of the rim 9, and the offset amount L1 is small. The protrusion is formed on one side in the axial direction (hereinafter, referred to as a protrusion direction) than the portion. The brake drum 2 is inserted into the inner wheel 6 so that the outer plate 8 of the brake drum 2 contacts the disc 8 of the inner wheel 6 and the discs 8 of both wheels 6 and 7 project from each other. It faces the other disk 8 on the direction side. Three or more mounting holes 11 corresponding to the mounting holes 4 of the brake drum 2 are arranged at equal intervals in the circumferential direction in the central portion of both discs 8 of both wheels 6 and 7, and the inner circumferential surface of the mounting holes 11 corresponds to the projecting direction. Are tapered in the opposite direction to form the taper portion 12.

Reference numeral 14 denotes a spacer, which is arranged between the disks 8 of both wheels 6 and 7 at equal intervals in the circumferential direction to maintain the distance between both wheels 6 and 7 at a predetermined interval, and the outer surface is substantially hexagonal. Thus, a circular hole is formed inside, and it is arranged between the corresponding mounting holes 11 of both wheels 6, 7. The outer peripheral surfaces of both ends of the spacer 14 are tapered portions 15 that are tapered outward in the axial direction, and are tapered to the tapered portions 12 of the respective mounting holes 11. Reference numeral 17 denotes a ring-shaped contact plate, which is in contact with the outer surface of the disk 8 of the outer wheel 7, and mounting holes 18 are formed at equal intervals in the circumferential direction so as to correspond to the mounting holes 11 of the disk 8. ing.

Numerals 20 and 21 are bolts exemplified as fastening means for fastening both wheels 6 and 7 via a spacer 14. The bolts 20 are attached to the mounting hole 4 of the brake drum 2 and the mounting hole 11 of the inner wheel 6. The spacer 14 is removably inserted and screwed to one end of the spacer 14. The bolt 21 is removably inserted into the mounting hole 18 of the contact plate 17 and the mounting hole 11 of the outer wheel 7 from the outside, and is removably inserted and screwed to the outer end of the spacer 14. When mounting a single tire on a vehicle, the outer wheel 7 is removed from the inner wheel 6 and bolts are attached to the mounting holes 4 and the inner wheel 6 mounting holes 11 of the brake drum 2 (the bolt 20 is used as this bolt). The inner wheel 6 only by inserting a nut into the bolt through a contact plate (the contact plate 17 may be used as the contact plate). Can be attached to the brake drum 2, and double tires can be easily changed to single tires.

According to the embodiment configured as described above, when the double tire is mounted, the offset amount L1 of the inner and outer wheels 6, 7 is reduced, so that the position of the inner wheel 6 is when the single tire is mounted. It does not move significantly inward of the vehicle body, and there is no fear that the tires mounted on the inner wheels 6 will interfere with the vehicle body without significantly remodeling the vehicle body. Since the spacers 14 are arranged to have a larger distance by the spacer 14, there is no fear that the sidewall portions of the tires mounted on both the inner and outer wheels 6, 7 will come into contact with each other. FIG. 3 shows a second embodiment of the present invention, in which the spacer 14 is made solid, and at the outer end thereof, a screw shaft portion 23 is formed continuously with the taper portion 15, A nut 24 is detachably screwed to the screw shaft portion 23.

[Effect of device]

 As described in detail above, according to the present invention, in a vehicle equipped with a single tire, the single tire can be changed to a double tire without modifying the vehicle body.
