发明名称 Sealing bellows, method for the production thereof and sealing bellows arrangement
摘要 A sealing bellows includes a sealing region disposed at a first end on a first end face and an attachment region disposed at a second end on a second end face. The sealing region includes an integrated first clamping element with a first internal diameter. The attachment region includes an integrated second clamping element with a second internal diameter. A casing is disposed in an axial direction of the sealing bellows between the sealing region and the attachment region with a third greatest internal diameter. The casing, the sealing region and the attachment region merge integrally into one another and are composed of a flexible rubber material, and, as a condition of production: the casing is substantially spherical; and the third greatest internal diameter of the casing is larger than the first internal diameter of the first clamping element and the second internal diameter of the second clamping element.

主权项 1. A sealing assembly, comprising: a ball joint having a housing, a ball pivot and a lever holder; and a sealing bellows disposed in an assembled state of the sealing bellows between the housing of the ball joint and the lever holder, the sealing bellows comprising: a sealing region disposed at a first end on a first end face, the sealing region including an integrated first clamping element, the first clamping element having a first internal diameter in the sealing region;an attachment region disposed at a second end on a second end face, the attachment region including an integrated second clamping element, the second clamping element having a second internal diameter in the attachment region; anda casing disposed in an axial direction of the sealing bellows between the sealing region and the attachment region, the casing having a third internal diameter, the third internal diameter of the casing, in a non-assembled state of the sealing bellows, being larger than the first internal diameter of the first clamping element and the second internal diameter of the second clamping element, the casing being substantially spherical in the non-assembled state of the sealing bellows and not having any radial bulging as a result of axial compression in the assembled state of the sealing bellows,wherein the easing, the sealing region and the attachment region merge integrally into one another and are composed of a flexible rubber material, wherein the sealing region contacts the ball pivot and the lever holder of the ball joint in a relatively movable manner, resting thereon and sealing the ball pivot and the lever holder dynamically, and wherein the attachment region contacts the housing of the ball joint in a relatively stationary manner, resting thereon and sealing the housing.
