摘要
An electric vehicle has an overhead current collector with a contact shoe (3) on a carrier (2). The carrier has a groove (4), open to the base of the shoe and closed at the end faces. There is pressurised fluid in the groove. If a certain drop in the pressure occurs, the pantograph is lowered. The mouth (8) of the groove is covered with an elastic material which presses against the base of the shoe. The pressure channel is sealed from the contact shoe over its whole length with a seal (6). The closure seal is under pressure. The pressure drops if the seal is damaged due to pressure. The width of the mouth is between 0.5 and 5 millimetres. The groove is wider below the mouth than at the mouth; for example, it is a circular slot. The base of the shoe may be plane or have a channel in it.
