Abstract

An end carriage that extends between a first free end and a second end intended to be connected to another carriage of the railway vehicle, the end carriage including a lower housing for a bogie made in proximity to the first end. The end carriage further includes at least one conduit, opening on the one hand into the lower housing, and opening on the other hand into the first end of the end carriage, and means for circulating air in the conduit.

First claim

The invention claimed is:

1. An end carriage of a railway vehicle, extending between a first free end and a second end intended to be connected to another carriage of the railway vehicle, the end carriage including a lower housing for a bogie made in proximity to the first end, comprising:
at least one substantially horizontal conduit, opening on the one hand into the lower housing, and opening on the other hand into the first end of the end carriage, and
an air circulator circulating air in the horizontal conduit, able to generate an air flow in the horizontal conduit, from the lower housing to the first end of the end carriage,
wherein:
the air circulator is able to generate an air flow in the horizontal conduit, from the first end of the end carriage towards the lower housing;
the air circulator is reversible, between a first configuration in which the air flow is generated from the lower housing towards the first end of the end carriage, and a second configuration in which the air flow is generated from the first end of the end carriage towards the lower housing.

2. The end carriage according to claim 1 , wherein the air circulator is in the first configuration when the end carriage is laid out at the rear of the railway vehicle, and in the second configuration when the end carriage is laid out at the front of the railway vehicle.

3. The end carriage according to claim 1 , wherein the air circulator is able to assume the first or the second configurations depending on operating conditions of the railway vehicle.

4. The end carriage according to claim 1 , wherein the air circulator is configured to vary the speed of a generated air flow, according to a speed of displacement of the end carriage.

5. The end carriage according to claim 1 , wherein the air circulator comprises at least one fan.

6. A railway vehicle, characterized in that it includes at least one end carriage according to claim 1 .

7. The end carriage according to claim 1 , wherein the air circulator is configured to generate an air flow in the horizontal conduit, from the lower housing to the first end of the end carriage.

8. The end carriage according to claim 1 , wherein the air circulator is configured to generate an air flow in the conduit, from the first end of the end carriage towards the lower housing.
