A track pad assembly for a continuous track vehicle includes a track plate and a polymer pad. The track plate includes a plate body having a tread surface, and one or more mesh arrays attached to the tread surface of the plate body. The polymer pad is attached to the mesh array(s) and to interstitial areas of the tread surface defined by cells of the mesh array(s), e.g., by press bonding in conjunction with an adhesive. The polymer pad may be made of an elastomer such as hardened rubber.

Vehicle track pad assembly and method

The invention is directed to an insert for a backing plate assembly for a composition friction brake shoe. The insert is particularly useful in the formation of a universal brake shoe for use with a trolley car braking system. The insert includes a central member having a first and second set of attachment posts extending from the respective ends thereof. These first and second sets of attachment posts are adapted for securing a first and second backing plate strap, respectively, thereto. A key bridge extends through a back portion of the central member and is configured for attachment to a brake shoe. A flange guide support extends from a side portion of the insert and includes legs defining a channel that runs parallel to the insert. The flange guide support is adapted for contacting a wheel flange to align a brake shoe with the wheel during braking of the vehicle.
