TH29059A - A set of centering clamps for the frame of the support structure of railroad wagons running on tracks. - Google Patents

Abstract

A railcar has a longitudinal wheel assembly and a pair of lateral frames extending between them, supported by the wheel assembly. Steel beams extend between the lateral frames to support the rail-running carriage. Bracing devices, connected to the lateral frames, control relative longitudinal movement between them. These bracing devices consist of a pair of support posts diagonally connected to the lateral frames on opposite sides of their centerlines. The posts generally intersect at the center of the lateral frames, and clamping assemblies are used to join them together. The clamping assembly consists of a pair of clamping plates, each with a formed rail and fitted to receive the individual support posts. Each clamping plate is welded to the support posts, and a tightening mechanism directly clamps the face surfaces of the clamping plates together. The clamping assembly inhibits relative movement between the support posts in the general horizontal plane while allowing limited relative movement in the vertical plane to accommodate rotational movement between the lateral frames.

Claims (3)

1. A railcar consists of a pair of longitudinally spaced wheel sets, a pair of transversely spaced side frames extending between and supported by these wheel sets, steel beams extending between these side frames to support the wagon body, and bracing devices connected between these side frames to control longitudinal movement. These bracing devices include a pair of support posts tilted opposite to the longitudinal axis of the railcar and each extending between the side frames. These support posts generally intersect at the center of the side frames, and clamping assemblies for attaching these posts at that intersection. These clamping assemblies include a pair of clamping plates, each generally rectangular in shape, with a center rail formed and adjusted to support one of the support posts. Each clamping plate is welded to one of the support posts, and tightening devices are made of direct contact between the facing surfaces of the clamping plates. Each metal plate of the clamp has four sides. These clamp plates are welded to one another along their adjacent sides to prevent relative movement between the supporting posts in the horizontal plane. 2. A railcar of the Ist claim, each fitted with two tightening devices, situated on each side of the crossing tracks. 3. A railcar of claim 1 in which each sheet metal has a long axis and a short axis with a rail of sheet metal extending along the long axis.
