Abstract
A pin for use in a track roller or bogie assembly comprises an outboard facing end, an inboard facing end having an aperture, a cylindrically-shaped external surface extending from the outboard facing end to the inboard facing end, and an inner surface extending inwardly from the aperture of the inboard facing end toward the outboard facing end and defining a cavity within the pin. The inner surface of the pin includes a groove disposed proximate the inboard facing end into which an outer surface of a resilient stopper expands to increase the pressure resistance of the pin and stopper to stopper being pushed or pulled from the pin.

A pin for use in a track roller or bogie assembly, the pin comprising:
- an outboard facing end;
- an inboard facing end, the inboard facing end having an aperture;
- a cylindrically-shaped external surface extending from the outboard facing end to the inboard facing end;
- and
- an inner surface extending inwardly from the aperture of the inboard facing end toward the outboard facing end and defining a cavity within the pin, the inner surface including a groove disposed proximate the inboard facing end, the groove having an inboard side surface that is approximately perpendicular to a longitudinal axis of the pin.
A cartridge pin assembly for use in a track roller or bogie assembly, the cartridge pin assembly comprising:
- a pin, comprising:
- an outboard facing end,
- an inboard facing end, the inboard facing end having an aperture,
- a cylindrically-shaped external surface extending from the outboard facing end to the inboard facing end, and
- an inner surface extending inwardly from the aperture of the inboard facing end toward the outboard facing end and defining a cavity within the pin, the inner surface including a groove disposed proximate the inboard facing end, the groove having an inboard side surface that is approximately perpendicular to a longitudinal axis of the pin;
- and
- an inboard stopper inserted into the inner surface through the aperture of the inboard facing end and engaging the inner surface to form a substantially water-tight seal at the inboard facing end of the cavity, wherein a portion of the inboard stopper is disposed within the groove.
A bogie assembly comprising:
- a pin, comprising:
- an outboard facing end,
- an inboard facing end, the inboard facing end having an aperture,
- a cylindrically-shaped external surface extending from the outboard facing end to the inboard facing end, and
- an inner surface extending inwardly from the aperture of the inboard facing end toward the outboard facing end and defining a cavity within the pin, the inner surface including a groove disposed proximate the inboard facing end, the groove having an inboard side surface that is approximately perpendicular to a longitudinal axis of the pin;
- an inboard stopper inserted into the inner surface through the aperture of the inboard facing end and engaging the inner surface to form a substantially water-tight seal at the inboard facing end of the cavity, wherein a portion of the inboard stopper is disposed within the groove;
- an outboard collar having an axial aperture, wherein the end of the pin proximate the outboard facing end is inserted into the aperture of the outboard collar and connected thereto;
- an inboard collar having an axial aperture, wherein the end of the pin proximate the inboard facing end is inserted into the aperture of the inboard collar and connected thereto;
- a hollow cylindrical bushing disposed about the external surface of the pin between the outboard and inboard collars;
- an outboard frame wall having an aperture, wherein the outboard collar is inserted into the aperture of the outboard frame wall and connected thereto;
- an inboard frame wall having an aperture, wherein the inboard collar is inserted into the aperture of the inboard frame wall and connected thereto;
- and
- a bogie arm having an opening there through, the bogie arm being disposed about and connected to the bushing between the outboard and inboard frame walls with the bushing and the bogie arm being rotatable about the pin.
