Abstract: A skid structure for a powertrain includes a pair of longitudinally extending members disposed about a central axis and in a mutually spaced apart relationship with one another. Each of the members includes a top wall; a bottom wall disposed in a spaced apart relation with the top wall; and a side wall connected at corresponding edges of the top and bottom walls to define a pocket therebetween. The pocket is configured to extend longitudinally along a length of the member and laterally along a width of the top and bottom walls. The skid structure further includes multiple gussets that are disposed within the pocket and interspaced from one another along the length of the member. Each gusset is configured to connect with at least two of the top wall, the bottom wall, and the side wall. The gussets are configured to support a weight of the powertrain thereon.

Abstract: A mounting structure for a driving unit and a driven unit of a locomotive is provided. The mounting structure includes a cradle, and an isolation system. The cradle includes a first portion, and a second portion. The first portion is configured to receive the driving unit therein. The second portion axially extends from the first portion and is configured to receive the driven unit therein. The isolation system is disposed on an outer surface of the cradle. The isolation system is configured to engage with a chassis of the locomotive to reduce transfer of vibrations from the driving unit, and the driven unit into the chassis.

Abstract: The present invention relates to a piston for an internal combustion engine. The piston includes a crown defined by a combustion surface and a cylindrical ring belt. The cylindrical ring belt has a first and a second ring groove extending about the circumference thereof, where the ring grooves are adapted to receive a first and a second piston ring. The combustion surface and the first ring groove define a first ring land therebetween. The first ring groove and the second ring groove define a second ring land therebetween. The cylindrical ring belt also has an elastic groove extending about the circumference thereof. The elastic groove has an upper wall and a lower wall interconnected by a radius "R", where the upper wall and the lower wall pivot about the radius "R", under loading of the piston to lower stress concentration within the crown.
