    • A radial shaft seal configured for receipt in a housing and about a shaft to sealingly isolate an air side of the seal from an oil side of the shaft seal is provided. The seal includes a mounting portion and a seal lip having an annular sealing surface extending between an oil side end and a free air side end. An annular bridge is connected to the oil side end of the seal lip by a first hinge and to the mounting portion by a second hinge. The bridge extends from the first hinge to the second hinge in radially overlying relation to the seal lip. An annular projection extends from the mounting portion axially away from the bridge. The projection has an oil side facing the seal lip and confronts the air side end of the seal lip upon the seal lip pivoting about the first hinge.
    • 提供径向轴密封件,其构造成用于容纳在壳体中并且围绕轴将密封件的空气侧与轴封的油面密封隔离。 密封件包括安装部分和密封唇缘,其具有在油侧端部和自由空气侧端部之间延伸的环形密封表面。 环形桥通过第一铰链连接到密封唇的油侧端部,并通过第二铰链连接到安装部分。 桥从第一铰链延伸到第二铰链,与密封唇缘呈径向上方的关系。 环形突起从安装部分轴向延伸离开桥。 突起具有面向密封唇的油面,并且在密封唇围绕第一铰链枢转时面对密封唇的空气侧端。
