ABSTRACT:
A current collector for transmitting energy between a contact wire and a motor coach having at least one collector shoe (1) and at least one suspension spring (16) with a positive stiffness, the suspension spring supporting the collector shoe which lies with a contact force from below and against the contact wire. The suspension spring (16) is arranged in parallel with a correction spring (17), the correction spring having a negative stiffness in a zero-crossing of its spring characteristic curve, which coincides with the spring travel of the suspension spring (16), which spring travel corresponds to the desired contact force.
