Abstract
The present embodiments relate to a braking apparatus, in particular for slowing down a carriage, with a brake pad, which is formed using a magnetic material, at least one first spring to press the brake pad onto a surface for the purposes of braking and an electromagnet. The brake pad, the at least one first spring and the electromagnet are disposed and embodied in such a manner that when current flows through the electromagnet a force acts on the brake pad by way of the magnetic material, compensating for the action of the at least one first spring on the brake pad in such a manner that the brake pad assumes a position, in which braking cannot take place due to the pressure of the brake pad. The braking apparatus allows braking independently of the material characteristics of the environment in which the braking apparatus is deployed.
