| The present disclosure increases the braking force of a parking spring brake mechanism without enlarging a device and without substantial increase in cost. The subject of the present disclosure is a brake cylinder device 2 provided with a parking spring brake mechanism 40 wherein a first piston 43 moves in a prescribed braking direction C. The brake cylinder device 2 is provided with a brake force transmitting section 37 having an inclined surface 38 that is inclined so as to press a brake output section 7 in an advancement direction A by moving along with the first piston 43 in the braking direction C. The inclined surface 38 includes a first inclined surface 38a provided in a distal end portion, and a second inclined surface 38b provided in a proximal end portion and inclined more than the first inclined surface 38a with respect to the advancement direction A. | ||||||

Brake arrangement, particularly for railway vehicles, where brake pads (7, 8) are in a facing relationship with a brake disc (9), pressed against the disc (9) by means of a pin (6) and at least one spring (5) acting on the pin (6), and where the motion of this pin (6) is derived from linear advance movement of a motion screw (2) with a nut (3) relative to rotary movement of a rotor of an electric motor (1). The nut (3) of the motion screw (2) as well as the pin (6) are in contact with the arm of the first order lever (4), while the area of contact of the nut (3) of the motion screw (2) and the lever (4) is farther from the axis of rotation of the lever (4) than the area of contact of the pin (6) and the lever (4). In order to reduce the coefficient of contact friction between the lever (4) and the nut (3) of the motion screw (2), the lever (4) or the nut (3) can be fitted, in the area of their contact, with a contact element (15) with rounded or spherical surface. In order to reduce the coefficient of contact friction between the lever (4) and the pin (6), the lever (4) can be fitted, in the area of their contact, with a rolling element.

| 85 | A RAIL VEHICLE BRAKE ACTUATOR WITH A BRAKE BLOCK HOLDER | EP12767679.9 | 2012-04-04 | EP2694350A1 | 2014-02-12 | LUNDGREN, Magnus |
| A rail vehicle brake actuator (1) has a brake block holder (4) suspended therefrom so as to be laterally movable during braking. Brake block hangers (5), which are rigid, are attached at their upper ends to brackets (2) on the actuator (1) by means of a joint (15) allowing relative laterally pivotable and rotatable movements and at their lower ends to the brake block holder. The lower ends of the brake block hangers (5) are laterally pivotally attached to a movable brake block holder axle (16) extending through a transverse bore in the brake block holder (4), and spring means (21) are arranged between the respective brake block hangers and the brake block holder. | ||||||

Die Erfindung betrifft eine Bremseinrichtung (1) eines Schienenfahrzeugs mit einer aktiven, durch ein Betätigungsorgan betätigbaren Druckluftbremse als Betriebsbremse beinhaltend wenigstens einen pneumatisch betätigten Aktuator (2, 4, 6, 8), der belüftet die Druckluftbremse zuspannt und sie entlüftet löst, sowie mit einer passiven Federspeicherbremse als Feststellbremse beinhaltend wenigstens einen gegen die Wirkung einer Speicherfeder pneumatisch betätigten Federspeicherbremszylinder (24, 26), der entlüftet die Federspeicherbremse zuspannt und sie belüftet löst, wobei der Federspeicherbremszylinder (24, 26) mit einem Druckluftvorrat (28) ständig in druckluftleitender Verbindung steht. Die Erfindung sieht vor, dass eine mit dem Druckluftvorrat (28) oder mit einem weiteren Druckluftvorrat in druckluftleitender Verbindung stehende, durch ein weiteres, separates Betätigungsorgan (52) steuerbare Ventileinrichtung (54, 55, 60) vorgesehen ist, welche bei Einsteuern eines durch das weitere Betätigungsorgan (52) erzeugtes Anforderungssignal zum Zuspannen der Feststellbremse den pneumatischen Aktuator (2, 4, 6, 8) der Druckluftbremse belüftet und diesen bei Einsteuern eines durch das weitere Betätigungsorgan (52) erzeugtes Anforderungssignal zum Lösen der Feststellbremse entlüftet.

| The invention relates to a brake actuator, especially for a rail vehicle brake, comprising a service brake unit with a brake force generator (24) for applying and/or releasing the brake, an accumulator brake unit with an energy accumulator device (10) for accumulating and delivering energy for applying the brake as an operative emergency brake and/or as a parking brake, and a force conversion device (100) for converting the energy that is provided by the brake force generator and/or the energy accumulator device (10) into a brake application movement. The invention provides that the brake actuator has an additional energy accumulator device (12) for accumulating and delivering energy for applying and/or releasing the brake. The additional energy accumulator device (12) and the brake force generator (24) can be designed in such a way that the force required of the brake force generator (24) during a braking operation in order to generate a defined brake application force level that is greater than zero but less than the maximum brake force is zero. | ||||||
