Current collector and method for power transmission

A method for transferring energy from a conductor rail to a vehicle by means of a current collector, the current collector being mounted on the vehicle using a carrying device of the current collector, a sliding piece of the current collector being moved relative to the conductor rail by means of a contact pressing device of the current collector, the sliding piece being pressed against the conductor rail in a sliding contact position using a contact pressing force and a sliding contact being formed, the contact pressing force being formed by a rocker and a spring member of a rocker unit of the contact pressing device, the sliding piece disposed on the rocker being moved by means of the rotatable spring member in one direction into the sliding contact position while generating the contact pressing force, a retaining element of the contact pressing device connecting the spring member to the carrying device,

• wherein
• the contact pressing device is positioned on the vehicle by means of a carrying element and a pivot mechanism of the carrying device, at least the rocker unit along with the sliding piece being moved from a storing position to the sliding contact position on the conductor rail and vice versa by means of the pivot mechanism, and wherein the pivot mechanism comprises an actuator, the actuator being connected to a lever of the retaining element and to the carrying element in such a manner that a linear movement of the actuator causes a pivoting of the rocker unit between the sliding contact position and the storing position.

A current collector for transferring energy from a conductor rail to a vehicle, the current collector comprising a carrying device, a contact pressing device and a sliding piece which forms a sliding contact surface, the carrying device for mounting the current collector being formed on a vehicle, the contact pressing device being formed such that the sliding piece is moveable relative to a conductor rail by means of the contact pressing device and pressable against the conductor rail for forming a sliding contact in a sliding contact position using a contact pressing force, the contact pressing device comprising a rocker unit for generating the contact pressing force using a rocker and a spring member, the spring member being rotatable in such a manner that the sliding piece disposed on the rocker is moveable in one direction into the sliding contact position while generating the contact pressing force, the contact pressing device comprising a retaining element which connects the spring member to the carrying device,

• wherein
• the carrying device has a carrying element and a pivot mechanism for positioning the contact pressing device on the vehicle, at least the rocker unit along with the sliding piece being moveable between the sliding contact position and a storing position away from the conductor rail by means of the pivot mechanism, and wherein the pivot mechanism comprises an actuator, the actuator being connected to a lever of the pivot mechanism and to the carrying element in such a manner that a linear movement of the actuator causes a pivoting of the lever and the retaining element having the rocker unit between the sliding contact position and the storing position.
