Abstract
A wear pad that is adapted to be attached to a grouser plate of a track-type machine includes a polyurethane pad having a first surface region that is adapted to engage a contact patch between the polyurethane pad and a ground region, the first surface region having a first area. A reinforcing member is at least partially embedded within the polyurethane pad and has a second surface region that faces the first surface region, wherein a second area of the second surface region is greater than fifty percent of the first area.
Claims23
A wear pad adapted to be attached to a grouser plate for a track-type machine, comprising:
- a polyurethane pad having:
- a first surface region that is adapted to engage a contact patch between the polyurethane pad and a ground region underneath the track-type machine, the first surface region having a first area, and
- a second surface region that is adapted to engage the grouser plate;
- a reinforcing member at least partially embedded within the polyurethane pad, the reinforcing member having:
- a third surface region on a first side of the reinforcing member, wherein the third surface region faces the first surface region, the third surface region is in contact with polyurethane of the polyurethane pad, and a second area of the third surface region is greater than sixty percent of the first area, and
- a fourth surface region on a second side of the reinforcing member opposite the first side, wherein the fourth surface region is in contact with the polyurethane of the polyurethane pad;
- and
- at least one first fastener associated with the reinforcing member and adapted to engage at least one second fastener associated with the grouser plate so as to secure the second surface region of the wear pad to the grouser plate.
A wear pad adapted to be attached to a grouser plate for a track-type machine, comprising:
- a polyurethane pad having:
- a first surface region that is adapted to engage a contact patch between the polyurethane pad and a ground region underneath the track-type machine, the first surface region having a first area, and
- a second surface region that is adapted to engage the grouser plate;
- a unitary reinforcing member at least partially embedded within the polyurethane pad, the unitary reinforcing member having:
- a third surface region on a first side of the unitary reinforcing member, wherein the third surface region faces the first surface region, the third surface region is in contact with polyurethane of the polyurethane pad, and a second area of the third surface region is greater than fifty percent of the first area, and
- a fourth surface region on a second side of the unitary reinforcing member opposite the first side, wherein the fourth surface region is in contact with the polyurethane of the polyurethane pad;
- and
- at least one first fastener associated with the unitary reinforcing member and adapted to engage at least one second fastener associated with the grouser plate so as to secure the second surface region of the wear pad to the grouser plate.
