Elastic base plate for track chains of track chain type vehicles

A base plate for track chains of a track chain type of vehicle, said base plate being for use on less favorable supporting soil and which is connectable to chain brackets of the track chain by bolts, said base plate comprising an elongated plate-like body having a sole surface and an upper side, a counter support at approximately the center of said body and having bores therethrough for receiving said bolts, lugs arranged on said upper side and extending from both dides of said counter support in the longitudinal direction and being chamfered from said sole surface in the direction of said counter support, said body being a one-piece moulded member comprised substantially completely of a rubber elastic crosslinked polyurethane, said counter support having a generally rectangular cross-section and being designed massively and said two lugs being bendable in the direction of the chain brackets, said base plate further comprising at least one one-piece insert which extends parallel to said sole surface and for substantially the entire length of said sole surface, said insert being made from a bendable elastic material whose bending modulus is significantly higher than that of the rubber elastic crosslinked polyurethane, and said insert being encased by said moulded polyurethane.
