Abstract
In the operation of a track type machine in highly abrasive material, premature wear of the track shoes has been a common occurrence. The present invention provides a track shoe that has a grouser that defines a plurality of grooves that extend in a direction that is substantially the same as that of the grouser. The grooves are formed on both the leading and trailing sides of the grouser and are filled with an abrasion resistant material. The grooves are arranged such that the strips of abrasion resistant material on the first side are aligned with the spaces between the strips on the opposite side and vice versa.
Claims12
A track shoe, comprising:
- a base portion having a width and a length;
- a grouser member having a first face and a second face disposed on the base portion and being positioned to extend from the base portion in a direction that is substantially normal to the base portion along substantially the entire width thereof;
- a first plurality of strips of abrasion resistant material defined along the first face of of the grouser member to extend substantially along the entire width of the base portion, said first plurality of strips being positioned in spaced relation to one another and extending in a direction that is substantially normal to the base portion.
In a track assembly having a plurality of track chains formed by a plurality of track links pinned together in spaced, parallel relation to one another, the improvement comprising:
- a track shoe having a base portion having first and second sides and a width and a length, said track shoe being mounted to the track assembly with the first side thereof in engagement with the respective spaced apart track links;
- a grouser member disposed on the second side of the base portion to extend in a direction that is substantially normal to the base portion along substantially the entire width thereof to define a contact surface on a terminal end thereof that is substantially parallel to the base portion;
- a plurality of strips of abrasion resistant material extending between the contact surface and the base portion, said strips being spaced from one another along the entire width of track shoe.
