They fit on the tracks to improve traction on ice. The T-34 has them, as do the various US M3 and M4 tank tracks. Most tanks with cast track links like German tanks or the Pershing didn't use them, but tracks with fairly flat pads like the Sherman did.

I always thought the things were originally designed as mud grousers, even though they were proably effective on ice as well. If you look at your refs, you'll see they were used just as if not more often on muddy terrain.
