Heavy-duty vehicle brake assembly with sealing interface

摘要

A heavy-duty vehicle brake assembly with a sealing interface includes a brake shoe, which includes a shoe table mounted on a web and a brake lining mounted on the shoe table. The shoe table is coated with a zinc-rich coating to form the sealing interface between the brake lining and the shoe table. The sealing interface resists the formation of corrosion cells on the brake shoe table, which in turn reduces the build-up of significant rust between the brake shoe table and the brake shoe lining, thereby preventing cracking and potential dislodging of the lining, while also facilitating replacement of linings when they eventually wear. A method of constructing a heavy-duty vehicle brake assembly with a sealing interface is also provided.

主权项

1. A heavy-duty vehicle brake assembly with a sealing interface, comprising:
a brake shoe including a shoe table mounted on a web; and a brake lining mechanically fastened to said shoe table, wherein the shoe table is coated with a zinc-rich coating that includes a zinc content of at least about seventy percent zinc by weight to form said sealing interface between said brake lining and said shoe table, whereby the sealing interface resists the formation of corrosion cells on the brake shoe table.
