Abstract
A traction carriage for an underground mining plow, comprising a traction carriage body which can be inserted into a cavity in a plow body and which on the rear side of a guide recess has a front part whose ends pointing in the direction of travel form stop surfaces for interacting with counterstop surfaces in the cavity of the plow body. According to the invention, a damping device having a damping action in both directions of travel is integrated into the front part of the traction carriage. In order to provide a low-maintenance damping device which allows a more favorable transmission of force between the stop surface on the traction carriage and the counterstop surface on the plow body, the coupling piece can be moved relative to the stop surfaces counter to the restoring force of a damping system of the damping device that is arranged between the stop surfaces.
