Abstract
An arrangement for self-steering, radial bogie, truck or vehicle frame for locomotives and other railroad vehicles, which mount unitized brakes to steering beams located either ahead and/or behind their respective leading and trailing wheelsets.
Claims31
A radial bogie for rail vehicles, comprising:
- a frame having longitudinally extending side frames laterally spaced by transoms, said side frames defining a longitudinal axis and having leading and trailing ends;
- leading and trailing wheelsets with axles supported on said frame;
- first and second steering beams pivotably mounted on said frame;
- traction links connected between said wheelsets and said steering beams;
- an inter-axle linkage connected between said steering beams;
- and
- unitized brakes mounted on said first and second steering beams.
A radial bogie for rail vehicles, comprising:
- a frame having longitudinally extending side frames laterally spaced by transoms, said side frames having side posts and defining a longitudinal axis;
- two end wheelsets with axles supported on said frame, said two end wheelsets being pivotably mounted on said frame;
- a center wheelset with an axle supported on said frame between said two end wheelsets, said center wheelset being substantially unpivotably connected to said side posts by traction links and being movable laterally to said longitudinal axis;
- steering beams for pivotally guiding said end wheelsets, each one of said steering beams being pivotably mounted on said frame behind a respective one of said end wheelsets;
- additional traction links connected between said end wheelsets and said steering beams;
- an inter-axle linkage connected between said steering beams;
- and
- a first set of unitized brakes mounted to said steering beams.
A radial bogie for rail vehicles, comprising:
- a frame having side posts, a leading end, and defining a longitudinal axis;
- first, second, and third wheelsets having axles being elastically supported on said frame;
- a pair of steering beams, one each located behind said first and third wheelsets away from said leading end of said frame and mounting a first set of unitized brakes;
- a second set of unitized brakes for braking said second wheelset;
- traction links coupling said first and third wheelsets to said steering beams, and said second wheelset to said side posts;
- and
- an inter-axle link coupling rotary motions about vertical axes of said steering beams to provide opposite transverse movement of said first and third wheelsets upon traversing curves, wherein each of said first set of unitized brakes includes an active lever and a brake shoe pivotably connected to a hanger, said active lever being connected to said brake shoe, and said hanger being pivotably connected to said frame, and wherein each of said second set of unitized brakes includes an active lever and a brake shoe pivotably connected to a hanger, said active lever being connected to said brake shoe, and said hanger being pivotably connected to a respective one of said side posts.
A railroad locomotive of the type comprising a carbody supported by at least one self steering radial bogie having a frame having longitudinally extending side frames laterally spaced by transoms, said side frames defining a longitudinal axis and having leading and trailing ends;
- leading and trailing driven wheelsets with axles supported on said frame;
- first and second steering beams for pivotally guiding said wheelsets, said first steering beam being pivotably mounted on said frame behind said leading wheelset away from the leading end of the frame, and said second steering beam being pivotably mounted on said frame behind said trailing wheelset towards the trailing end of said frame;
- traction links connected between said wheelsets and said steering beams;
- an inter-axle linkage connected between said steering beams;
- and unitized brakes mounted on said steering beams.
Running gear for rail vehicles comprising at least one bogie having a frame having longitudinally extending side frames laterally spaced by transoms, said side frames defining a longitudinal axis and having leading and trailing ends;
- leading and trailing wheelsets with axles supported on said frame;
- first and second steering beams for pivotally guiding said wheelsets, said first steering beam being pivotably mounted on said frame behind said leading wheelset away from the leading end of the frame, and said second steering beam being pivotably mounted on said frame behind said trailing wheelset towards the trailing end of said frame;
- traction links connected between said wheelsets and said steering beams;
- an inter-axle linkage connected between said steering beams;
- and unitized brakes mounted on said steering beams.
