Abstract
An endless loop track for a track vehicle including an endless loop support. A plurality of rigid plates are bolted by bolts onto the endless loop support. The rigid plates have a traction surface. Each of the bolts have a pointed head that protrudes past the traction surface thereby providing resistance to sideways slippage.
Description
TITLE OF THE INVENTION:
Endless loop track for a track vehicle FIELD OF THE INVENTION
The present invention relates to endless loop tracks for track vehicles.
BACKGROUND OF THE INVENTION
Side slippage of track vehicles when traversing a slLope is a potentially dangerous problem. When the orientation of the vehicle changes due to slippage, an operator can lose 1 o control of the vehicle and the vehicle can overturn. Previously, in order to obtain better traction in winter conditions or in uneven terrain, bars have been welded onto the tracks of the track vehicle. While this solution is initially effective, the bars tend to bend and break under wear. Furthermore, the process of welding the bars to the tracks of the track vehicle adversely affects the tracks by shortening their lifespan.
i5 SUMMARY OF THE INVENTION
What is required is alternative method of preventing side slippage of track vehicles.
According to the present invention there is provided an endless loop track for a 2 o track vehicle including an endless loop support. A plurality of rigid plates are bolted by bolts onto the endless loop support. The rigid plates have a traction surface.
Each of the bolts have a pointed head that protrudes past the traction surface thereby providing resistance to sideways slippage.

Referring to FIGURE 3, each rigid plate 16 has a plurality of apertures 20 adapted to receive bolts 18. Each rigid plate 16 also has a traction surface 22 which is raised above a substantially planer surface 24.
1 o Referring to FIGURE 2, bolts 18 that are used to bolt rigid plates 16 to endless track support 12 have pointed heads 26 that protrude past traction surface 22 thereby providing resistance to sideways slippage of a track vehicle 28 illustrated in FIGURE 6.
Pointed heads 26 of bolts 18 have a plurality of circumferentially positioned planer faces 30. A stem 32 of each bolt 18 has threads 34 adapted to mate with a securing nut 36.
Referring to FIGURE 7, pointed heads 26 of bolts 18 are provided with a carbide stud 38 making them more wear resistant. Referring to FIGURE 3, in the illustrated embodiment, bolts with flat heads 40 are also used in addition to bolts 18 with pointed heads 26 to bolt rigid plates to endless loop support 12, althoL~gh it will be appreciate that bolts 18 with pointed heads 26 could be used on their own.
Operation:
The use and operation of endless loop track for a track vehicle will now be described with reference to FIGURES 1 through 7. Referring to FIGURE 6, endless loop 2 ~ track as described above, is provided on a track vehicle 28, haring operation of track vehicle 28, pointed heads 26 of bolts 18 provide extra traction, especially in winter conditions or in uneven terrain to prevent track vehicle 28 from slipping sideways.
Referring to FIGURE 5, existing prior art endless loop track for a track vehicle generally referenced by numeral 100 can be modified by removing bolts 114 with flat heads 118 3 o illustrated in FIGURE 1, and replacing them with bolts 18 that have pointed heads 26 that protrude past traction surface 22 illustrated in FIGURE 2 thereby providing resistance to sideways slippage of a track vehicle 2$ illustrated in FIGURE 6.
In this patent document, the word "comprising" is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article '°a"
does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.
i o It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention as hereinafter defined in the Claims.
