Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a snowmobile track belt, and more particularly to a snowmobile track belt in which a stud for slip prevention is detachably attached without damaging the track belt body.

[0002]

[Prior art]

 Conventionally, as shown in FIGS. 3 and 4, a track belt for a snowmobile includes a sprocket-shaped drive wheel (not shown), a driven wheel 3, and an idler wheel (not shown), which are provided on a drive track portion 1 provided at a rear portion of a vehicle body frame. A plurality of endless track belt main bodies 4 (three in this embodiment) are wound around, and the slide rails 5 are arranged on the back surface of the track belt main body 4 on the ground side so as to be in sliding contact with each other. Has been done.

The track belt body 4 is connected by a plurality of rods 6 which are embedded in the belt width direction at predetermined intervals, and the weight of the snowmobile body is supported by the slide rails 5. The weight of the vehicle body is distributed over the entire width of the track belt main body 4 via the rod 6. On the surface of the conventional track belt body 4, a conical stud 7 for slip prevention is attached as shown in FIG. 2, and the stud 7 forms a through hole in the track belt body 4. The bolts and nuts 8 are fastened to the through holes.

[0004]

[Problems to be solved by the device]

 However, since the conventional stud 7 is attached to the track belt body 4 by forming a through hole, the track belt body 4 is damaged, which reduces the durability of the track belt body 4 and shortens its life. There is also a problem that the tension is applied to the track belt body 4 during traveling, so that the through hole expands and the stud 7 for slip prevention falls off.

In order to solve the above-mentioned problems, the applicant of the present invention, as a result of earnest research, has distributed the weight of the vehicle body to the entire width of the track belt body 4 via the rod 6, and the slide rail. 5 that is located below the caulking metal fitting 4 attached to the track belt body 4 is subjected to a particularly large amount of distributed load, so that the caulking metal fitting 9 and the rod 6 can be prevented from slipping at arbitrary positions. The stud 7 for use is detachable and firmly fixed upright.

The present invention has been devised in view of such conventional problems, and can effectively prevent the track belt body from being damaged and the stud from falling off even during normal traveling of the snowmobile. In addition to improving the driving force of a snowmobile, it is also possible to improve the anti-slip effect of the track belt body, and also to provide a snow mobile track belt in which a stud can be provided at any position. It is intended.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the gist of the present invention is that a stud holding member is integrally provided on a rod, and a stud for slip prevention is detachably erected and fixed to the stud holding member.

[0008]

[Action]

 This invention is constructed as described above, and is provided with a stud holding member for removably standingly fixing an anti-slip stud at an arbitrary position of the rod embedded in the belt width direction, so that a normal snowmobile Even during running, the track belt itself will not be damaged or the stud will not fall off.The stud is detachably erected on the stud holding member that is integrally provided on the rod. The track belt for snowmobiles can be made lighter without providing a stud base that covers the metal fittings body, the driving force of the snowmobile can be improved, and the slip prevention effect of the track belt body is also improved. It is something that can be done.

[0009]

[Example of device]

 An embodiment of the present invention will be described below with reference to the accompanying drawings. The same components as those in the conventional example are designated by the same reference numerals and the description thereof will be omitted. FIG. 1 is a sectional view of a stud mounting portion showing a first embodiment of the present invention, 4 is a track belt main body, 6 is a rod as a lateral rigid member embedded in the belt width direction. At an arbitrary position in the longitudinal direction, a stud holding member 15 is fixed to cover the rod 6 and to attach a stud 14 for slip prevention. A screw hole 17 for screwing a bolt 16 formed at the base end portion of the stud 14 is formed on the upper portion of the stud holding member 15, and the screw hole 17 is formed at the base end portion of the stud 14. After the bolt 16 is screwed, it is fixed by the press nut 18.

FIG. 2 shows a second embodiment of the present invention, in which a stud holding member 15 for mounting the stud 14 for slip prevention is provided on the caulking metal fitting 10. is there. That is, in this embodiment, the metal fitting body 12 constituting the caulking metal fitting 10 is caulked and fixed to the rod 6 as a laterally rigid member at the mounting portion of the caulking metal fitting 10 via the cushioning rubber 11. . A stud holding member 15 for fixing the stud 14 for preventing slippage and fixing the stud 14 is fixed to the rod 6 at the portion where the metal fitting body 12 is caulked. A screw hole 17 for screwing a bolt 16 formed on the base end portion of the stud 14 is formed on the upper portion of the stud holding member 15. The screw hole 17 is formed on the base end portion of the stud 14. After the bolt 16 is screwed, it is fixed by the press nut 18.

Therefore, the anti-slip stud 14 is supported by the rod 6 via the stud holding member 15, and the rod 6 is fixed by caulking with the metal fitting body 12 via the cushioning rubber 11 as described above. Has been done. In this invention, since the stud 14 is supported by the stud holding member 15 provided on the rod 6 as described above, the stud 14 can be erected at any position in the longitudinal direction of the rod 6 which is embedded in the belt width direction. In comparison with the conventional case, it is possible to provide the stud 14 on the portion of the crimping metal fitting 10. Therefore, the track belt body may be damaged or the stud 14 may be damaged even during normal traveling of the snowmobile. It is possible to improve the driving force of the snowmobile and to prevent the slipping of the track belt body, and it is necessary to provide a stud base that covers the metal fitting body 12. Since it does not exist, the weight of the snowmobile track belt can be reduced.

[0012]

[Effect of device]

 In this invention, the stud holding member is integrally provided on the rod as described above, and the anti-slip stud is detachably erected and fixed to the stud holding member. Can be erected at any position in the longitudinal direction of the rod that is buried in the direction, so that it is possible to effectively prevent the track belt body from being damaged and the stud from falling off during normal running of the snowmobile. Not only can the driving force of the snowmobile be improved, the anti-slip effect of the track belt body can be improved, and the weight of the snow mobile track belt can be reduced.

Further, since the stud is configured to be replaceable, there is an effect that another stud can be easily attached and replaced even if it is damaged or comes off.
