Abstract
A brake system has at least two energy sources and at least two electromechanical wheel brakes. A first wheel brake is directly connected exclusively to a first of the energy sources and is not directly connected to a second of the energy sources. A second wheel brake is directly connected to the second energy source and is not directly connected to the first energy source. The wheel brakes are each configured to, in the event of failure of the energy source of the respective other wheel brake, supply energy to the other wheel brake from the remaining energy source.
Claims19
A brake system comprising:
- at least two energy sources;
- at least two electromechanical wheel brakes;
- a first wheel brake of the at least two electromechanical wheel brakes directly connected exclusively to a first of the at least two energy sources and indirectly connected to a second of the at least two energy sources;
- a second wheel brake of the at least two electromechanical wheel brakes directly connected to the second energy source and indirectly connected to the first energy source;
- and
- wherein in an event of failure of one of the at least two energy sources the other of the at least two energy sources supplies energy to the other wheel brake that is indirectly connected to that energy source;
- wherein the wheel brakes each have one first interface for connection to the respective energy source and one second interface for connection to the respective other wheel brake;
- and
- wherein the interfaces to the at least on energy source and the respective other wheel brake are connected separably to the wheel brake via switching devices.
