Abstract
A drawbar for a vehicle coupler includes a drawbar tail, the drawbar tail configured at a distal end for connecting to a vehicle, and at a proximal end for engagement with a drawbar body; a drawbar body, the drawbar body configured for receiving a draft gear, the drawbar body further defining a path for movement of the proximal end of the drawbar tail. The drawbar body and drawbar tail are connected by a releasable connection. A block inserted via an opening in the drawbar body blocks the path to restrain movement of the drawbar tail during towing, after release of the releasable connection.
Claims15
A drawbar for a rail vehicle coupler comprising:
- a first portion configured at a distal end for connecting to a first vehicle;
- a second portion comprising a housing for receiving a dampening device, for connection to a second vehicle, the second portion configured for engagement with a proximal end of the first portion;
- and
- a block inserted in the second portion via an opening in a sidewall of the second portion;
- wherein the first and second portions are configured for connection via a release mechanism, and, wherein, responsive to release of the release mechanism, the release being responsive to application of buff forces above a threshold greater than zero, the first and second portions are slidably movable in a first direction, and slidably movable in a second direction, opposite to the first direction, to the block.
A drawbar for a vehicle coupler, comprising:
- a drawbar tail, the drawbar tail configured at a distal end for connecting to a vehicle, and at a proximal end for engagement with a drawbar body;
- the drawbar body, the drawbar body configured for receiving a draft gear, the drawbar body further defining a path for linear movement of the proximal end of the drawbar tail along a longitudinal axis of the drawbar body,
- a key inserted via an opening in a sidewall of the drawbar body to rest in the path.
A drawbar body for a vehicle coupler, comprising:
- a portion for releasable connection to a draft gear;
- a top plate, having upstanding parallel rails, the parallel rails each having grooves defined in inner faces of the rails, for receiving and defining a linear path along a longitudinal axis of the drawbar body for travel of a plate of a drawbar tail;
- and
- an opening through a wall of the drawbar body and into at least one of the grooves, for receiving a key.
