Patent ID: 8714376

Claim:
A heavy-duty pivot plate adjusting joint for a heavily loaded drawbar for connecting railroad cars to multi-part car sections and for generating horizontal and/or vertical restoring torques in car bodies during a development of longitudinal pressure forces in a block train to avoid derailing and consequences thereof, the heavy-duty pivot plate adjusting joint comprising: a drawbar end plate; an end coupling rod part disposed at an end of the drawbar; a pressure-side spring washer disposed at least on a pressure side; a car-side support bearing plate for connecting to an under frame of a railroad car; only one pressure-side spring column, at a drawbar end of the drawbar just one said end coupling rod part is disposed with said only one pressure-side spring column in such a way as to connect the drawbar to said car-side support bearing plate via said drawbar end plate; an adjusting joint pivot plate disposed between said drawbar end plate and said car-side support bearing plate; said drawbar end plate, said adjusting joint pivot plate and said car-side support bearing plate having contact faces, at least one of said contact faces defining a pivot plate rolling face for transmitting a pressure force, between one of said adjusting joint pivot plate and the drawbar or said car side support bearing plate; and spring travel limiters having pressure contact faces disposed either on said drawbar end plate, on said adjusting joint pivot plate, or on said car-side support bearing plate, and define a support-cage-shaped space for receiving said pressure-side spring washer, and are at a defined distance from an assigned one of said pressure contact faces, transmitting the pressure force, in a direction of a pressure-side spring travel.
