Track shoe pad structure assembly
A track shoe pad structure assembly is connected to a track chain of a caterpillar vehicle. The track shoe pad structure assembly includes a track shoe pad, a reinforcing unit and an elastic element. The track shoe pad is for connecting to the track chain and includes a notch. One side of the reinforcing unit is detachably connected to the notch, and the reinforcing unit includes a base frame disposed on the track shoe pad and at least one supporting rib disposed on one side of the base frame which is located away from the track shoe pad. The elastic element is detachably connected to the other side of the reinforcing unit, and the elastic element includes at least one recessed trough for containing the supporting rib.
1. A track shoe pad structure assembly which is connected to a track chain of a caterpillar vehicle using a plurality of screw members, the track shoe pad structure assembly comprising:
a track shoe pad comprising:
a track shoe plate having a width and a length, and a first surface and a second surface, the track shoe plate comprising a plurality of apertures each formed through the track shoe plate to interconnect the first surface and the second surface; and
three notch walls each extending along a length direction of the track shoe plate and protruding upward from the first surface of the track shoe plate, the notch walls being spaced apart along a width direction of the track shoe plate to thereby form two notches each between two adjacent notch walls, wherein a plurality of the apertures are positioned corresponding to each notch;
a reinforcing unit comprising:
a base frame disposed on the track shoe pad and formed as a plate having a plurality of bends, the base frame having a width and a length, and a first surface facing away from the track shoe pad and a second surface facing toward the track shoe pad, wherein the base frame comprises two exterior shoulder portions that extend along a length direction of the base frame and that are on opposite sides of the base frame along a width direction of the base frame, each of the exterior shoulder portions being formed by a bend away from the first surface of the base frame and a bend in the width direction of the base frame and abutting against one of the outer ones of the notch walls of the track shoe pad, wherein the base frame further comprises a center shoulder portion which extends along the length direction of the base frame, the center shoulder portion being formed by a bend away from the first surface of the base frame at a position between the two exterior shoulder portions and abutting against a center one of the notch walls of the track shoe pad, wherein a recessed portion is formed between one of the exterior shoulder portions and the center shoulder portion, and another recessed portion is formed between the other exterior shoulder portion and the center shoulder portion, wherein the base frame is formed with a plurality of opening holes which pass through the base frame and respectively correspond in position to the apertures of the track shoe plate of the track shoe pad; and
a plurality of solid members disposed on the first surface of the base frame respectively at locations corresponding to the opening holes of the base frame, wherein a plurality of the solid members is provided in each of the recessed portions, and each of the solid members extends between and contacts one of the exterior shoulder portions and the center shoulder portion, wherein each of the solid members comprises a blind screw hole that is positioned corresponding to one of the opening holes of the base frame; and
an elastic element detachably connected to the first surface of the base frame of the reinforcing unit, wherein the elastic element has an inner surface formed with a plurality of recessed troughs that respectively receive the solid members.
