Abstract
Official abstract text for this publication.
A device for coupling tilting railroad cars onto a high-speed railroad train comprises a coupler and a shock absorber held in a shock absorber frame, each joined by a coupling pin via a coupling joint. The frame includes a front inner surface with a front end wall opening and a cylindrical surface extending to a semi-circular concave inner surface. The joint includes a rounded convex surface engaged with a semi-circular concave surface, a circumferential surface of a short cylinder receiving the rear portion of the coupler, and an insertion hole which is provided in a direction perpendicular to the axis of the short cylinder. The frame has a removal hole and an air removal pin of the coupling pin facing each other at a position to rotate at a predetermined angle in a circumferential direction in the assembled state, and at a position coaxial with the coupling pin in the assembled state.
First claim
Opening claim text (preview).
The invention claimed is: 1. A device for coupling high-speed railroad cars comprising: a coupler; a shock absorber held in a shock absorber frame; and a coupling joint which joins the coupler and the shock absorber held in the shock absorber frame by a coupling pin, wherein the shock absorber frame has a front-end wall partially cut in an inverted cone shape so as to have a front inner surface with a semi-circular concave inner surface to which a cylindrical inner surface e…
