Electromechanical assembly for a braking system of a railway vehicle, control system of the electromechanical assembly, and braking system including the electromechanical assembly and the control system

A control system for an electromechanical assembly of a braking system, wherein the electromechanical assembly comprises:

• a flywheel arranged to accumulate kinetic energy sufficient to operate the electromechanical assembly for at least one emergency brake action, service brake action, or parking brake action of the braking system;
• and
• wherein the control system comprises:
• a control unit arranged to control at least actuation of a first electric motor, a first engagement means, and a locking means of the electromechanical assembly, wherein the first engagement means is arranged to couple rotatably a primary transmission shaft, connected rotatably to the first electric motor, to a secondary transmission shaft, and wherein the locking means is coupled to the secondary transmission shaft and arranged to stop a rotation of the secondary transmission shaft;
• power supply means connected at their input to an electrical power source and arranged to output a stabilized voltage;
• first electric power converter means connected to the first electric motor and adapted to supply energy to said first electric motor by conversion of the stabilized voltage present at an output of said power supply means, wherein said first electric power converter means are further adapted to provide a stabilized voltage by conversion of a variable voltage generated by at least the first electric motor when driven rotatably by the flywheel;
• and
• control means of the power supply of said control unit, adapted to supply energy to at least said control unit starting from the stabilized voltage present at the output of said power supply means or by the stabilized voltage provided by the first electric power converter means.

A braking system for a railway vehicle, the braking system including:

• an electromechanical assembly for the braking of the railway vehicle comprising a flywheel arranged to accumulate kinetic energy sufficient to operate the electromechanical assembly for at least one emergency brake action, service brake action, or parking brake action of the braking system;
• a control system for the electromechanical assembly;
• and
• braking means arranged to apply a braking force, directly or indirectly, to at least one wheel of the railway vehicle;
• wherein the application of the braking force is controlled by extension or retraction movement of a linear actuator of the electromechanical assembly, the linear actuator being extendable from a first retracted position, wherein two ends of the linear actuator are at a first distance, to a second extended position, in which said ends of the linear actuator are located at a second distance, greater than the first distance, said linear actuator being arranged to actuate said braking system.
