Abstract
A suspension strut includes a suspension strut bearing and a deflector seal. The suspension strut bearing has an upper portion mounted above a lower portion and a bearing seal mounted therebetween. The upper portion does not rotate with a steerable assembly while the lower portion does, with the upper portion including a lower surface adjacent to a seal opening. The deflector seal is elastomeric and is a toroidal shape, having a radially inner portion and a radially outer portion. The inner portion is secured against the lower portion of the strut bearing, and the outer portion is cantilevered outward from the inner portion to allow for elastic flexing of the outer portion. The outer portion allows for upward elastic flexing into contact with the lower surface of the upper portion of the strut bearing when a fluid or contaminant impinges upon a lower surface of the outer portion.
