20100001578 | Hydraulic Brake Comprising a Safety Function - A braking device for braking a moving mass includes a movably guided coupling member for pressing a brake lining against a braking surface, a brake cylinder, filled with a hydraulic liquid, a brake piston which is movable inside the brake cylinder and which is connected to the coupling member. At least one hydraulic line can be connected to the brake cylinder. The device ensures the moving masses to be reliably decelerated. For that purpose, a fluidic-mechanical safety brake device is used to connect the brake cylinder to the one or more hydraulic lines. | 01-07-2010 |
20100019567 | SELF-ENERGIZING HYDRAULIC BRAKE - A device for decelerating or braking a moving mass includes a movably guided coupling member for pressing a brake lining against a braking surface and a brake actuator, filled with hydraulic liquid and connected to the coupling member, for generating a pressure force that can be passed into the brake lining through the coupling member. The brake lining is connected to a pressure transducer that can be fastened on a frame of the mass to be decelerated or braked through a connecting device. The pressure transducer has a hydraulic liquid-filled supporting cylinder and a supporting piston interacting therewith. The supporting cylinder communicates with a brake cylinder through hydraulic lines. This allows an improved adjustment of deceleration or braking. For this purpose, a regulating device adjusts the brake force depending on a predetermined theoretical value. | 01-28-2010 |
20120192757 | BRAKE SYSTEM HAVING SMART ACTUATOR FOR BRAKING A RAIL-GUIDED VEHICLE - A brake system for braking a rail vehicle has an actuator, which is equipped for installation in its totality in a bogie of the rail vehicle and provided with a braking force F so as to create a braking movement of at least one pressing part, and an energy storage device which is connected to the actuator via a supply line. A brake controller supplies control signals for controlling the brake system, which enables secure braking of the rail vehicle. The actuator has a control connection, which is connected to the brake controller for receiving the control signals via a data line, wherein the control connection is connected to a logic unit of the actuator that is configured to set the braking force F in dependence on the control signals. | 08-02-2012 |
20140046514 | ACTUATOR FOR A BRAKE SYSTEM OF A RAIL VEHICLE - An actuator for a brake system of a rail vehicle has a set-value detection unit that outputs a set value or a set value corrected by a reducing signal of an anti-skid control device for a decelerating force or a decelerating torque to a set-value control device. The latter controls the set value to a first output set value. A switch-over device connects an output of the set-value control device to a input of a set-value/force conversion device in a first switching position. In a second switching position, the set-value/force conversion device receives the signal from a fall-back unit. Braking devices convert an actual value of the force into an actual value of the decelerating force or decelerating torque. When impermissible deviations from a fast braking set value in a fast-braking operation are found, the switch-over device switches from the first to the second switching position. | 02-13-2014 |
20150367822 | Brake unit for a Vehicle and Vehicle having such a Brake Unit - A brake unit for a vehicle which can be mounted on running gear of the vehicle has devices for making available a regulated braking force and a passive emergency braking force. In order to permit safe braking by the emergency braking force, even in the case of a fault during the provision of the regulated braking force, there is provision that the devices are of suitable configuration to make available the passive emergency braking force in a load-corrected fashion and include a pressure signal transmitter and a load corrector for correcting the load of the passive emergency braking force. The load corrector sets a preload pressure of the pressure signal transmitter as a function of electrical output signals of a fallback device to a load-corrected set point value. | 12-24-2015 |
20150367826 | BRAKE UNIT FOR A VEHICLE AND VEHICLE WITH A BRAKE UNIT OF THIS TYPE - A brake unit for a vehicle, in particular a rail vehicle, includes an electrohydraulic setpoint value-force-conversion device having a container for providing hydraulic fluid, a brake cylinder connected to the container via a hydraulic line system and having brake pistons, and control devices suitably constructed so as, under the action of electric output signals of a setpoint-value-regulating device, to adjust an actual value, which acts upon the brake cylinder, of a hydraulic pressure in the brake cylinder. In a structurally advantageous manner, one of the control devices is a pump unit with which hydraulic fluid can be pumped out of the container into the brake cylinder and another of the control devices is suitably constructed to allow hydraulic fluid to flow out of the brake cylinder into the container. A vehicle with such a brake unit is also provided. | 12-24-2015 |
20150367870 | Brake Unit for a Vehicle and Vehicle having such a Brake Unit - A brake unit for a vehicle, in particular a rail vehicle, has a brake cylinder, a brake piston and a device for adjusting a clearance. The latter has two first stops that strike against each other when the brake unit is opened. One of the first stops is formed on a blocking element that is functionally connected to the brake piston. In order to be able to open the brake unit beyond the clearance, a blocking member is in engagement with the blocking element under the force of a pre-stressing spring. The blocking element is blocked by the blocking member when the first stops strike. Actuators displace the blocking member that is in engagement with the blocking element counter to a force of the pre-stressing spring into a position detached from the blocking element. | 12-24-2015 |
20150375763 | BRAKE UNIT FOR A VEHICLE AND VEHICLE HAVING SUCH A BRAKE UNIT - A brake unit for a vehicle has a brake cylinder, a brake piston guided axially in the brake cylinder and a device for adjusting a clearance. The device has two first stops, which strike against each other when the brake unit is opened, and two second stops, which strike against each other when the brake unit is closed. One of the first stops is formed on a blocking element functionally connected to the brake piston. One of the second stops is formed on the blocking element. A blocking member is in engagement with the blocking element under the force of a pre-stressing spring such that the blocking element is blocked by the blocking member when the first stops strike and can continue to latch in relation to the blocking member under the force of the brake piston when the second stops strike. | 12-31-2015 |
