Abstract

An oil-free compressor for a rail vehicle includes a multi-piece compressor housing, a first piston cylinder supported in a first opening in the compressor housing, a second piston cylinder supported in a second opening in the compressor housing, a multi-piece crankshaft assembly supported by the compressor housing, and an optionally filtering air plenum in fluid communication with the compressor housing interior to provide a volume of air to the compressor housing interior. The crankshaft assembly is linked to pistons of the first and second piston cylinders by respective connecting rods. The connecting rods connect to a wrist pin associated with each of the pistons, and the wrist pins are respectively supported by a dry lubricant bushing to the associated piston. The compressor housing may have a first housing portion and a second housing portion forming respective halves of the compressor housing.
