SWIVEL JOINT WITH ROTATION ANGLE MEASUREMENT

摘要

The present invention relates to a rotary joint, in particular for the articulated connection of a front part and of a rear part of a bus, consisting of a housing (1) which is divided into two housing parts (3, 4) in a plane perpendicular to an axis of rotation (2) of the joint. The two housing parts (3, 4) are rotatable about the axis of rotation (2) in relation to each other and are connected to each other in a manner sealed against an egress of hydraulic fluid located in a housing interior (5). A pinion (6) of a rack and pinion drive of a vibration damper is mounted rotatably in the first housing part (3), and the second housing part (4) forms a drive element and is connected to the pinion (6) for conjoint rotation. An angle of rotation measuring device (11) is arranged in a receiving chamber (10) within the housing (1) in a manner coaxial with respect to the axis of rotation in the rotary centre of the rotary joint and interacts with the second housing part (4) for measuring the angle of rotation, and the receiving chamber (10) is sealed off against an ingress of the hydraulic fluid.
