Abstract
The invention relates to a sleeper frame for a track system for railborne vehicles, particularly for a ballasted track, consisting of several cross-ties (1) provided in the direction transverse to the track, and one or several longitudinal supports (2) connected with the cross-ties, wherein one cross-tie (1), respectively, substantially forms the outer delimitation of the sleeper frame in the longitudinal direction, with outer bearings (4) and fixtures (3) for the rails (6) being provided on the outer cross-ties, and with a continuous or quasi-continuous bearing for the rails (6) being provided between the outer rail bearings (4).
Claims20
A sleeper frame for a track system for railborne vehicles, the sleeper frame being adapted to be aligned end-to-end with additional such frames to provide substantially continuous support for rails associated with the track system, the sleeper frame including:
- (a) at least one longitudinal support;
- (b) a first cross-tie connected to each longitudinal support to form an outer delimitation at a first longitudinal end of the sleeper frame;
- (c) a second cross-tie connected to each longitudinal support to form an outer delimitation at a second longitudinal end of the sleeper frame opposite the first longitudinal end;
- (d) a first outer rail bearing and rail fixture set mounted on the first cross-tie and a second outer rail bearing and rail fixture set mounted on the second cross-tie for each rail to be supported on the sleeper frame;
- and
- (e) a continuous or quasi-continuous intermediate bearing for each rail to be supported on the sleeper frame, each respective intermediate bearing being supported on the sleeper frame between the first outer rail bearing and rail fixture set and second outer rail bearing and rail fixture set for the respective rail.
A sleeper frame for a track system for railborne vehicles, the sleeper frame being adapted to be aligned end-to-end with additional such frames to provide substantially continuous support for rails associated with the track system, the sleeper frame including:
- (a) two laterally spaced apart longitudinal supports extending substantially parallel to a longitudinal axis of the sleeper frame;
- (b) a first cross-tie transversely connected to each longitudinal support to form a first longitudinal end of the sleeper frame;
- (c) a second cross-tie transversely connected to each longitudinal support to form a second longitudinal end of the sleeper frame opposite the first longitudinal end;
- (d) for each rail to be supported on the sleeper frame, a first outer rail bearing and rail fixture set mounted on the first cross-tie and a second outer rail bearing and rail fixture set mounted on the second cross-tie;
- and
- (e) an intermediate bearing for each rail to be supported on the sleeper frame, each respective intermediate bearing being supported on the sleeper frame between the first outer rail bearing and rail fixture set and the second outer rail bearing and rail fixture set for the respective rail, and wherein
- (f) each intermediate bearing exhibits relatively less stiffness than the first and second outer rail bearings between which the respective intermediate bearing is supported;
- and
- (g) when each respective intermediate bearing is in a relaxed condition, a bearing surface of the respective intermediate bearing lies in a plane higher than a bearing plane of the first and second outer rail bearings between which the respective intermediate bearing is supported.
A track system for railborne vehicles, the track system including:
- (a) a plurality of sleeper frames;
- (b) each sleeper frame including:
- (i) two laterally spaced apart longitudinal supports extending substantially parallel to a longitudinal axis of the respective sleeper frame;
- (ii) a first cross-tie transversely connected to each longitudinal support at a first longitudinal end of the respective sleeper frame;
- (iii) a second cross-tie transversely connected to each longitudinal support at a second longitudinal end of the respective sleeper frame opposite the first longitudinal end;
- (iv) for each rail to be supported on the respective sleeper frame, a first outer rail bearing and rail fixture set mounted on the first cross-tie and a second outer rail bearing and rail fixture set mounted on the second cross-tie;
- and
- (v) an intermediate bearing for each rail to be supported on the respective sleeper frame, each respective intermediate bearing being supported on the respective sleeper frame between the first outer rail bearing and rail fixture set and the second outer rail bearing and rail fixture set for the respective rail;
- and
- (c) the plurality of sleeper frames being arranged so that each longitudinal end of each respective sleeper frame is aligned with and lies adjacent to either the first or second longitudinal end of a next adjacent one of the sleeper frames.
