Vehicle track assembly
View Patent ↗A vehicle track assembly includes a track framework including a frame structure, a drive drum, and a plurality of idler wheels supported by the frame structure. A drive track is arranged about and cooperatively engages the plurality of idler wheels and the drive drum. An adjustable ski is connected to the framework. The ski may extend forward of the track. An adjustable rearward extending ski may extend rearward of a track assembly. An indicator pole is coupled to the assembly to provide an indication of the angle of rotation of the assembly.

an adjustable ski connected to the framework and extending forward of the track, wherein the ski is adjustable amongst a plurality of inclination angles, wherein the adjustable ski comprises at least one mounting arm having first and second mounting holes, wherein one of the first and second mounting holes has an elongated slot that allows the ski to be rotated to adjust the inclination angle to a select inclination angle, and wherein the at least one mounting arm is connected to one threaded fastener by a ski mounting fastener, and wherein the at least one mounting arm is directly connected to a first threaded fastener connected to a first axle associated with a first idler wheel via a first ski mounting fastener and is directly connected to a second threaded fastener connected to a second axle associated with a second idler wheel positioned rearward of the first idler wheel via a second ski mounting fastener.
2. The track assembly of claim 1 further comprising a rearward extending ski connected to the frame structure and extending rearward of the track.
3. The track assembly of claim 2 , wherein the rearward extending ski is adjustable to a select inclination angle.
4. The track assembly of claim 1 further comprising an indicator pole connected to the frame structure approximately at a center of the drive drum to provide an indication of an angle of rotation of the track assembly.
5. The track assembly of claim 4 , wherein the indicator pole extends generally vertical when the track assembly is generally on a horizontal surface and rotates with angular rotation of the track assembly.
6. A vehicle track assembly comprising:
a track framework comprising a frame structure, a drive drum, and a plurality of idler wheels each supported on the frame structure by a threaded fastener connected to an axle;
a drive track arranged about and cooperatively engaging the plurality of idler wheels and the drive drum; and
a ski connected to the framework and extending adjacent to the track, wherein the ski comprises at least one mounting arm connected to at least one of the idler wheels, wherein the at least one mounting arm is connected to a first threaded fastener connected to a first axle associated with a first idler wheel by a first ski mounting fastener connected to the first threaded fastener and is directly connected to a second threaded fastener connected to a second axle associated with a second idler wheel positioned rearward of the first idler wheel by a second ski mounting fastener connected to the second threaded fastener.
7. The track assembly of claim 6 , wherein the ski is adjustable to select an inclination angle amongst a plurality of inclination angles.
8. The track assembly of claim 7 , wherein the at least one mounting arm has first and second mounting holes receiving the respective first and second ski mounting fasteners, wherein one of the first and second mounting holes has an elongated slot that allows the ski to be rotated to adjust the inclination angle.
9. The track assembly of claim 6 , wherein the ski extends forward of the track.
10. The track assembly of claim 6 , wherein the ski comprises a rearward extending ski connected to the frame structure and extending rearward of the track.
11. The track assembly of claim 6 further comprising an indicator pole connected to the frame structure approximately at a center of the drive drum to provide an indication of an angle of rotation of the track assembly.
12. A vehicle track assembly comprising:
a track framework comprising a frame structure, a drive drum, and a plurality of idler wheels each supported on the frame structure by a threaded fastener connected to an axle;
a drive track arranged about and cooperatively engaging the plurality of idler wheels and the drive drum; and
an adjustable ski connected to the framework and extending forward of the track, wherein the ski is adjustable amongst a plurality of inclination angles, wherein the adjustable ski comprises at least one mounting arm having first and second mounting holes, wherein one of the first and second mounting holes has an elongated slot that allows the ski to be rotated to adjust the inclination angle to a select inclination angle, and wherein the at least one mounting arm is connected to one threaded fastener by a ski mounting fastener, wherein the plurality of idler wheels comprises a first idler wheel having a first axle connected to the frame structure via a first threaded fastener and a second idler wheel having a second axle connected to the frame structure via a second threaded fastener, and wherein the at least one mounting arm of the ski is directly connected to the first and second threaded fasteners on the first and second axles and fastened thereto via first and second ski mounting fasteners, respectively.
13. A vehicle track assembly comprising:
a track framework comprising a frame structure, a drive drum, and a plurality of idler wheels supported by the frame structure;
a drive track arranged about and cooperatively engaging the plurality of idler wheels and the drive drum;
an indicator pole connected to the frame structure approximately at a center of the drive drum and extending from the framework, wherein the indicator pole rotates with angular rotation of the track assembly to provide an indication of the angle of rotation of the track assembly;
wherein the indicator pole is generally vertical when the track assembly is in a generally horizontal position on a horizontal surface and rotates with angular rotation of the track assembly;
the track assembly further comprising a ski having at least one mounting arm extending from the framework, wherein the ski is an adjustable ski that is adjustable amongst a plurality of inclination angles to an angle of inclination;
wherein the at least one mounting arm has first and second mounting holes, wherein one of the first and second mounting holes has an elongated slot that allows the ski to be rotated to adjust the inclination angle; and
wherein the at least one mounting arm is connected to a first threaded fastener on a first axle of a forwardmost first idler wheel by a first ski mounting fastener and is connected to a second threaded fastener on a second axle of a second idler wheel positioned rearward of the first idler wheel by a second ski mounting fastener.
