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]

 2. Description of the Related Art Conventionally, as shown in FIGS. 2 and 3, a track belt for a snowmobile has a sprocket-shaped drive wheel 2, a driven wheel 3, and an idler wheel (not shown) 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 slide rails 5 are disposed on the ground-side back surface of the track belt main bodies 4 so as to be in sliding contact with each other. ing.

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. Paying attention to the fact that a particularly large amount of distributed load is applied to the caulking metal fitting 9 that is located under 5 and is attached to the track belt body 4, the anti-slip stud 7 can be attached to and removed from the caulking metal fitting 9. It was designed to be attached firmly.

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 being able to improve the driving force of the snowmobile, it is also possible to improve the anti-slip effect of the track belt body, and because it is possible to stand and fix it without the need for special parts for attaching studs, the number of parts is reduced. It is an object of the present invention to provide a track belt for a snowmobile, which can reduce the amount of the assembly workability and can reduce the weight of the caulking metal fittings.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention has a stud for preventing slippage which is provided upright on the crimping metal fitting, and the stud for preventing slippage has at least one end portion of the metal fitting body for crimping the cushioning rubber. The gist of the invention is that it is removably erected and fixed to a horizontal stud holding member that has been extended.

[0008]

[Action]

 In this invention, the studs are provided on the caulking metal fittings on which the slide rails are slidably mounted, so that the track belt body is not damaged or the studs fall out even during normal running of the snowmobile. Also, since the stud is detachably erected and fixed to the horizontal stud holding member that extends at least one end of the metal fitting body, it is erected and fixed without providing a component for mounting the stud. As a result, the number of parts can be reduced, the workability of assembly can be improved, and the weight of the caulking metal fitting can be reduced.

[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 caulking metal fitting 10 showing a first embodiment of the present invention, 4 is a track belt main body, 6 is a rod as a lateral rigid member, and this rod 6 has a cushioning rubber. A metal fitting body 12 constituting the caulking metal fitting 10 is fixed by caulking via 11.

At least one end portion 12 a of the metal fitting body 12 is extended upward to form a horizontal stud holding member 13, and the stud holding member 13 has a bolt formed at the base end portion of the stud 14. A screw hole 16 for screwing the screw 15 is formed. Reference numeral 17 denotes a holding nut which is tightened after the bolt 15 formed at the base end portion of the stud 14 is screwed into the screw hole 16.

Therefore, the anti-slip stud 14 can be detachably held by the stud holding member 13 extending upward from the terminal portion 12a of the metal fitting body 12, and as a result, there is no need to provide a component for mounting the stud 14. It can be fixed upright, the number of parts can be reduced, the workability of assembling can be improved, and the weight of the caulking metal fitting 10 can be reduced.

In the present invention, the stud 14 is erected and fixed to the stud holding member 13 extending upward from the terminal portion 12a of the metal fitting body 12 as described above, so that the stud 14 is erected at an arbitrary position. Compared with the conventional one, since the stud 14 is provided in the portion of the caulking metal fitting 10, it may be said that the track belt body may be damaged or the stud 14 may come off during normal traveling of the snowmobile. In addition, the driving force of the snowmobile can be improved, the slip prevention effect of the track belt body can also be improved, and it is not necessary to provide a stand for covering the metal fitting body 12, so that the caulking can be performed. It is possible to reduce the weight of the metal fitting 10, in other words, reduce the weight of the snowmobile track belt.

[0013]

[Effect of device]

 In this invention, a stud for preventing slippage is erected on the crimping metal fitting portion as described above, and the stud for slipping prevention extends at least one end portion of the metal fitting body for crimping the cushioning rubber upward. Since it is detachably erected and fixed to the horizontal stud holding member, it is possible to effectively prevent the track belt body from being damaged and the stud from falling off even during normal running of the snowmobile. It is possible to improve the anti-slip effect of the track belt body, and the stud can be attached to and detached from the horizontal stud holding member which extends at least one end of the metal fitting body upward. Since it is fixed upright, it can be fixed upright without providing any parts for attaching the studs. On it is possible to improve the gender, there is this and can effect to reduce the weight of the caulking fittings.

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.
