Title: Heavy-duty pivot plate adjusting joint

Abstract: A heavy-duty pivot plate adjusting joint for railroad freight cars connects multi-part car sections. To this end, the adjusting joint is configured such that each drawbar end is provided with only one end coupling rod part having a spring column, and the drawbar is connected by way of the drawbar end plates to the support bearing plates of an under frame provided on a car side. Each adjusting joint is provided with an adjusting point pivot plate, wherein a pivot plate roll surface is present directly at the pivot plate or at the adjoining contact surfaces transmitting pressure force, the surfaces having a spherical or two-dimensional shape. A configuration of the adjusting joints in a "regular embodiment" is proposed, wherein the distance of the transmission end points of balance is smaller than the distance of the spring travel limiters.
