Abstract
A connecting sleeve suitable for the production of a push-pull link bar includes a main body, a coupling section which is formed or arranged on the outer circumferential side on the main body, and a through bore, characterized in that the connecting sleeve has a first seal which is arranged at least partially on the outer circumferential side and a second seal which closes at least the through bore.
Claims19
A push-pull link bar comprising:
- at least one connecting sleeve;
- a tubular body which, on an inner circumferential side, has at least one mating coupling section which corresponds to a coupling section of the connecting sleeve, the at least one connecting sleeve and the tubular body coming into contact with one another in an assembled position in a contact region which is formed by the coupling section and the mating coupling section, wherein the contact region is sealed toward an outside;
- and
- wherein the sealing of the contact region takes place by way of a first seal and a second seal, and
- wherein, in the assembled position, the first seal is clamped in between an undercut of the connecting sleeve and an end face of the tubular body, the end face being oriented at least partially obliquely with respect to a longitudinal axis of the tubular body.

A push-pull link bar comprising:
- at least one connecting sleeve;
- a tubular body which, on an inner circumferential side, has at least one mating coupling section which corresponds to a coupling section of the connecting sleeve, the at least one connecting sleeve and the tubular body coming into contact with one another in an assembled position in a contact region which is formed by the coupling section and the mating coupling section, wherein the contact region is sealed toward an outside;
- and
- wherein the sealing of the contact region takes place by way of a first seal and a second seal,
- wherein the at least one connecting sleeve has the first seal which is arranged at least partially on an outer circumferential side of the push pull link bar and the second seal which closes at least a through bore in the push-pull link bar, and
- wherein a maximum external diameter of the second seal is greater than a maximum external diameter of an end section of a main body into which end section the second seal is introduced at least partially.
