Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
174 words
A sealing bellows for a ball joint in which the ball is received in a socket in a housing with the axis of the ball stud normally at an acute angle to the axis of the housing, said sealing bellows having a large opening on one end to encircle the housing for sealing of that end, a smaller opening on the opposite end to encircle the ball stud for sealing at that end, the plane of said second opening being normally at an acute angle to the plane of said larger opening, said bellows intermediate its ends extending radially outwardly from the axis of said socket on the side of said acute angle a greater distance than on its opposite side to form a radial asymmetric bulge on the side of said acute angle, so that as said ball stud moves toward a position coaxial with said socket, the circumferential wall portion of said bellows will be flexed without substantially stretching the material and without exerting force on the sealing ends of the bellows.
Claim 2
Dependent Claim
174 words
A sealing bellows for a ball joint in which the ball is received in a socket in a housing with the axis of the ball stud normally at an acute angle to the axis of the housing, said sealing bellows having a large opening on one end to encircle the housing for sealing of that end, a smaller opening on the opposite end to encircle the ball stud for sealing at that end, the plane of said second opening being normally at an acute angle to the plane of said larger opening, said bellows intermediate its ends extending radially outwardly from the axis of said socket on the side of said acute angle a greater distance than on its opposite side to form a radial asymmetric bulge on the side of said acute angle, so that as said ball stud moves toward a position coaxial with said socket, the circumferential wall portion of said bellows will be flexed without substantially stretching the material and without exerting force on the sealing ends of the bellows.
Claim 3
Dependent Claim
37 words
A sealing bellows combination according to claim 1, in which the asymmetric bellows is provided with marking means to indicate the proper assembly position of said asymmetric bellows relative to the housing to which it is connected.
