Patent ID: 7055705

Claim:
A central buffer coupling for coupling a first rail car body with a second, adjacent rail car body of a multiple-unit rail vehicle comprising: a) a linking housing in a rail car body comprising a plurality of pressure devices; b) an action linked coupling shaft having a longitudinal axis; c) a coupling head pivotally connected by the coupling shaft to the linking housing of the rail car body; d) a pivoting unit for pivoting the coupling shaft comprising a guide, an activation device for positioning the guide and the action linked coupling shaft in any selected position of a planned pivoting range, and a plurality of pressure surfaces symmetric to said longitudinal axis of the coupling shaft, said guide participating in a horizontal pivoting movement of the coupling shaft that runs about a vertical pivot axis, each pressure surface of said plurality of pressure surfaces corresponding to a respective one of said plurality of pressure devices for bringing about horizontal re-centering of the coupling shaft, each pressure device being supported on the linking housing of the coupling shaft in order to bias the corresponding pressure surface against the guide; and e) a pivoting device connecting the guide with the activation device, said pivoting device being engageable with the guide and releasable in a center position of the guide; wherein said pivoting device has a link comprising a contour, said central buffer coupling further comprises a guide pin guided in the contour, said guide comprises a driver accommodating the guide pin, and said guide pin is engageable with the driver.
