Abstract
A contact rail device for an at least partly electrically driven motor vehicle. The contact rail device comprises at least one busbar for electrical contact-connection of an electric machine to a supply device for the electric machine In this case, the busbar comprises at least one compensation bow for compensation of temperature-dependent changes in length.
Claims9
A contact rail device for an at least partly electrically driven motor vehicle comprising:
- a plurality of busbars for electrical contact-connection of an electric machine to a supply device for the electric machine, wherein:
- each busbar comprises at least two compensation bows for compensation of temperature-dependent changes in length of the busbar,
- the plurality of busbars have different lengths and the at least two compensation bows are disposed at different positions along the length of the busbars with respect to the supply device, and
- the at least two compensation bows of each busbar is formed in an S-shape that comprises at least two oppositely oriented C-bows per busbar with a folded edge in between each of the at least two oppositely oriented C-bows.
