Abstract
Railcar adapter, for connecting a railcar body to a bearing, having a bearing seat side secured to the bearing and a frame seat side mounted in a bogie frame of the railcar body is provided. The railcar adapter includes a top cover in contact with the railcar body, forming the frame seat side, a bearing seat adapted to be mounted on the bearing, forming the bearing seat side and at least one damping element located between the top cover and the bearing seat.
Claims17
A railcar adapter, for connecting a railcar body to a bearing, comprising:
- a bearing seat side configured to be secured to the bearing,
- a frame seat side configured to be secured to a bogie frame of the railcar body,
- a top cover configured to contact the railcar body and forming the frame seat side,
- a bearing seat configured to be mounted on the bearing and forming the bearing seat side, and
- at least one damping element located between the top cover and the bearing seat,
- wherein, the bearing seat has an inner surface configured to radially contact the bearing and a flat outer surface having a central cutting, the at least one damping element and the top cover extending into the cutting, and
- wherein the central cutting is delimited by two parallel first lateral surfaces perpendicular to a first axis of symmetry of the adapter, two opposed first rounded surfaces connecting the first lateral surfaces, and a bottom in radial contact with the at least one damping element, and wherein
- the at least one damping element is delimited by two parallel second lateral surfaces perpendicular to the first axis of symmetry of the adapter, two opposed second rounded surfaces connecting the second lateral surfaces, a substantially flat inner surface in radial contact with the bearing seat and a substantially flat outer surface, each second lateral surface being provided with first cuttings and each second rounded portions being provided with second cuttings.
