摘要： 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, and a multi-piece crankshaft assembly supported by the compressor housing. 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 at least a first housing portion and a second housing portion. The first housing portion and the second housing portion may form respective halves of the compressor housing that are secured together with mechanical fasteners.

摘要： A clamp and quick release mechanism for clamping and releasing a cylindrical linkage to a rod-like member comprises a locking ring located on the rod-like member and a clamping ring. The inner surface of the clamping ring and the outer surface of the locking ring are configured such that rotation of the clamping ring in one direction will compress the locking ring and rotation in the other direction will allow expansion of the locking ring.

摘要： The brake shoe support assembly is able to track the lateral movement of a wheel, typically a wheel on an axle truck that allows lateral wheel movement. In operation, a flange of the wheel pushes on one side of the brake shoe support assembly, pushing it along a pin, and compressing a resilient biasing structure. As the wheel returns to a center or neutral position, the compressed resilient biasing structure expands pushing the brake shoe support assembly back to an original or neutral position. The resilient biasing structure also minimizes the lateral movement of the brake shoe support assembly down the wheel taper under normal braking loads thus preventing shoe ride-off. The resilient biasing structure may be enclosed in a housing adapted to prevent the intrusion of contaminants.
