The diaphragm air seal may include a first flange having a first sealing surface sealingly engaging the cylindrical housing, a second flange having a second sealing surface sealingly engaging the traction motor, and an air seal body extending between the flanges. The air seal body may be formed from an elastomeric material and have an S-shaped transverse cross-section. An assembly may include the diaphragm air seal and may further include an air seal weldment having a radial weldment flange and an axial weldment flange extending axially outwardly from the radial weldment flange so that the first flange of the diaphragm air seal may be disposed on and sealingly engaging the radial weldment flange.
