    Abstract: Dust boot assemblies for providing grease relief while preventing or minimizing infiltration of contaminants into a cavity in the dust boot and between the surfaces of a greased joint coupled to the dust boot. Some such dust boot assemblies include two-piece grease relief inserts having a body and a shield, wherein the body includes grease relief route(s) and the shield prevents or minimizes infiltration of contaminants into the grease relief route(s). Other dust boot assemblies include one-piece grease relief inserts with integral body and shield components. Some grease relief routes include axial and radial channels. Grease relief inserts are inserted under an edge of a dust boot. A dust boot skirt covers grease relief ports through which excess grease is relieved to the external environment. The grease relief insert is located to in a portion of the dust boot experiencing limited or zero movement.

  • Patent number: 7793952
    Abstract: A ball joint integrated knuckle and an assembling method thereof is provided. The ball joint integrated knuckle includes: a knuckle integrating a housing formed with a first screw thread on its one side surface; and a ball joint having a thread seat formed with a second screw thread, wherein the ball joint is integrated into the knuckle by combining the first screw thread of the housing of the knuckle with the second screw thread of the thread seat of the ball joint. Thus, it is possible to easily attach/detach the ball joint with respect to the knuckle by combining/removing the ball joint using the first screw thread, formed in an inner circumferential surface of the housing integrally formed with the knuckle, and the second screw thread formed in an external circumferential surface of the thread seat. Also, according to the present invention, the ball joint is not manufactured as a finished product, but provided as kit.
