摘要: A piston assembly and method of making the same are disclosed. An exemplary piston assembly may include a multi-piece skirt secured to a piston crown having a ring belt portion defining a cooling gallery. The crown may include one or more a struts extending away from the ring belt portion to define a wrist pin bore(s). The piston skirt assembly may include two separate portions that each have at least one skirt support securing the respective skirt portion to the strut. A cover plate may be provided that is secured between a radially inner surface of the ring belt portion of the crown and a radially outer surface of the strut, such that the cover plate defines in part the cooling gallery.
