Definitions
- the present invention relates to a railway vehicle capable of running on rails comprising:
- a mechanical compensation brake having a movable portion adapted to come into contact with the rail for applying a braking force.
- the braking system in the metro area has two distinct braking modes, which are based on three different technical devices.
- the two known braking modes are service braking, namely the braking mode in a normal situation requiring a deceleration which is carried out gradually (for example: arrival at the station, curvature of the track, deceleration of the preceding train) and the emergency braking which is carried out in cases not foreseen over short distances.
- the service braking mode is controlled by the traction / dynamic braking unit.
- the emergency braking mode is activated by a train line. If there is no potential on this line, the motor vehicles inhibit their traction / dynamic braking (electrical) equipment as soon as possible and apply emergency braking.
- the known braking devices are the electrodynamic brake and the mechanical friction brake for the internal braking devices, and the compensation brake constitutes an external braking device.
- the electrodynamic brake uses the electric propulsion motor of the vehicle, acting as a generator when it is driven by the wheels and dissipating the electrical energy produced at the output of the motor, for example in a resistive load.
- the adhesion between the wheels and the rails can be reduced, for example because of rain or the presence of sheets on the rails, and also by the use of the mechanical friction brake itself.
- the braking of the mechanical friction brake is no longer ensured correctly.
- a mechanical friction brake failure may occur.
- the braking of the railway vehicle is not sufficient and the safety must be ensured by an increase in the safety distances between the trains or low-speed train control programs.
- an additional safety brake independent of the rail wheel contact called the compensation brake.
- the compensation brake is activated only in the emergency braking mode and only in case of insufficient braking, or in case of malfunction of the mechanical friction brake.
- the compensation brake allows, in known manner, a mechanical action directly on the rails under electromagnetic control.
- the compensation brake is formed of magnetic pads, which ensure a high braking value of the railway vehicle.
- the compensation brake is able, in case of friction on the rails, to "clean" the rails, and thus increase the coefficient of adhesion between the rails and the wheels, in the case where the rails are wet. for example.
- the current magnetic pads forming the compensation brakes are used exclusively in emergency braking mode, that is to say in extreme situations and are then used to the maximum of their braking capacity. This is why the magnetic pads providing the function of compensation brakes are controlled in all or nothing.
- the variation of the deceleration between the moment before the start of operation of the magnetic pads and the moment of their putting into operation can be important.
- This variation in deceleration also known as the Jerk effect, causes an uncomfortable feeling for passengers.
- the invention thus aims to reduce the safety distance between two successive vehicles on the same track, and to provide a vehicle that allows to ensure greater traffic while remaining safe.
- the subject of the invention is a railway vehicle of the aforementioned type, characterized in that it comprises a compensation brake comprising means for regulating the braking force applied to the rail as a function of the effective deceleration of the railway vehicle, the regulation means being able to apply to the brake of compensation of the intermediate braking forces comprised between extreme braking forces of the compensation brake.
- the on-board compensation brake makes it possible to safely provide additional deceleration as much as necessary for the effective deceleration of the train, that is to say the intensity of which can be modulated, by an independent solution of the wheel-rail contact.
- This principle makes it possible to increase the braking capacities over the entire line and to compensate for the braking decreases associated with loss of grip or possible braking failures on the rolling stock.
- the compensation brake proceeds by real-time acquisition of the effective deceleration of the train and by the calculation of the additional compensation force to be applied just necessary, and finally by the application of braking in a flexible manner thanks to the magnetic friction pads installed on board.
- This modulable compensation brake is mainly intended for use in emergency braking mode, but could also be used in service braking mode.

- said railway vehicle comprises:
- control means for measuring the effective deceleration of the railway vehicle; and the control means are adapted to calculate the braking force to be applied to the rail by the compensation brake, as a function of the difference between the reference deceleration value and the effective deceleration value;
- the control means are adapted to continuously vary the braking force applied to the rail by the compensation brake, depending on the actual deceleration value;
- the compensation brake comprises several electromagnets, or several permanent magnets, whose position can be remotely controlled, controlled independently to ensure the braking force;
- the internal braking means of the vehicle comprise: an electrodynamic brake comprising a motor drive motor capable of operating as a generator while being driven by the wheels; and
