Abstract
The present invention relates to a closure package (1) for closing a damper tube (10) for a vibration damper, with a main body (11) which is designed for sealing arrangement in the damper tube (10) and through which a piston rod (12) of the vibration damper can be sealingly guided, and wherein the main body (11) has an opening in which a guide bush (13) for guiding the piston rod (12) is inserted and wherein at least one sealing unit (14, 15) is provided for sealing contact with the piston rod (12). According to the invention, the guide bush (13) has a circumferential collar (16) pointing radially outwards at one end face and adjoined by the sealing unit (14).
Claims10
A closure package (1) for closing off a damper tube (10) of a vibration damper, having a main body (11) which is designed for sealing arrangement in the damper tube (10) and through which a piston rod (12) of the vibration damper can be sealingly guided, and wherein the main body (11) has an opening in which a guide bushing (13) for guiding the piston rod (12) is inserted, and wherein at least one seal unit (14, 15) for sealing contact with the piston rod (12) is provided, characterized in that the guide bushing (13) has, on an end side, a circumferential, radially outwardly pointing collar (16), adjacent to which the seal unit (14) is arranged.
The closure package (1) as claimed in one of the preceding claims, characterized in that a closure plate (18) is provided, by means of which the seal unit (14, 15) is held in the main body (11), wherein the outer seal element (15) forms a support ring between the rod sealing element (14) and the closure plate (18).
The closure package (1) as claimed in one of the preceding claims, characterized in that the guide bushing (13) is formed in one piece from a plastics plain bearing material.
The closure package (1) as claimed in one of the preceding claims, characterized in that the guide bushing (13) is pressed into the opening in the main body (11).
The closure package (1) as claimed in one of the preceding claims, characterized in that the collar (16) has an axial thickness which substantially corresponds to the wall thickness of the guide bushing (13).
The closure package (1) as claimed in one of the preceding claims, characterized in that the guide bushing (13) projects radially inward beyond the adjacent rod sealing element (14) in the contact region between the guide bushing (13) and the seal unit (14).
A vibration damper having a damper tube (10) which is closed off by means of a closure package (1), wherein the closure package (1) has a main body (11) which is arranged for sealing arrangement in the damper tube (10) and through which a piston rod (12) of the vibration damper is sealingly guided, and wherein the main body (11) has an opening in which a guide bushing (13) for guiding the piston rod (12) is inserted, and wherein at least one seal unit (14, 15) for sealing contact with the piston rod (12) is provided,
- characterized in that the guide bushing (13) has, on an end side, a circumferential, radially outwardly pointing collar (16), adjacent to which the seal unit (14) is arranged.
