Abstract: An electromechanical system is to be fixedly arranged in a central cavity of a wheel hub of a vehicle including a generator for generating electric current, an electric motor for actuating an actuator, the actuator, and a storage system for storing electrical energy. The actuator is linearly movable along a longitudinal axis of the electromechanical system. A coupling device couples the motor to a radially inner part of the actuator. The storage system includes a plurality of storage elements which are radially arranged around the outside of the longitudinal axis and the motor and at least some of which are spaced apart from one another in a circumferential direction. A radially outer part of the actuator is formed radially beyond the storage elements, wherein connecting elements of the actuator rigidly connect the radially inner part and the radially outer part to one another and reach through between the storage elements.
