Abstract

A current collector for a rail vehicle intended for international transport includes a support bringing two contact strips into electrically conductive contact with a contact wire on the roof of the rail vehicle. Each contact strip has a first length and a contact strip extension at each end. Each contact strip extension is rotatably mounted and connected to a respective end of the contact strip. In a first position the contact strip extensions are hinged inwards, such that a resulting total length of the contact strip with the associated contact strip extensions corresponds to the first length of the contact strip. In a second position, the contact strip extensions are hinged outwards, such that the resulting total length of the contact strip with the associated contact strip extensions corresponds to a second length of the contact strip which is greater than the first length.

Dependent claims

A current collector for a rail vehicle intended for cross-border transport, the current collector comprising:

two contact strips each having a first length, ends and contact strip extensions;
each of said contact strip extensions being connected to a respective one of said ends and being rotatably mounted about a vertical axis at said respective one of said ends;
a support configured to orient said two contact strips on a roof of the rail vehicle transversely relative to a direction of travel of the rail vehicle and said support configured to bring said two contact strips into electrically conductive contact with a contact wire;
in a first position, said contact strip extensions each being rotated about a respective vertical axis relative to a respective contact strip resulting in a total length of said contact strip with said respective contact strip extensions corresponding to said first length of said contact strip;
and
in a second position, said contact strip extensions each being rotated about a respective vertical axis relative to a respective contact strip resulting in a total length of said contact strip with said respective contact strip extensions corresponding to a second length being greater than said first length.
