Patent number: 10471940Abstract: A compressed air brake device for a rail vehicle with a direct, electropneumatic brake has a brake control unit which has a brake control device with connected brake actuators and a brake pilot control pressure sensor connected to the brake actuators. An independent monitoring control unit is arranged in parallel to the brake control unit. The monitoring control unit has a monitoring control device with connected monitoring actuators and a monitoring pilot control pressure sensor. A monitoring pilot control pressure at the output of the monitoring actuators is closed-loop controlled using the monitoring pilot control pressure sensor. The higher pressure of a brake pilot control pressure and the monitoring pilot control pressure or, in the case of a fault of the brake control unit, the monitoring pilot control pressure can be relayed to the brake cylinder.Type: GrantFiled: November 29, 2016Date of Patent: November 12, 2019Assignee: Siemens Mobility GmbHInventors: Mike Mauder, Stefan Reinicke, Manfred Wiesand

Patent number: 10112633Abstract: A rail vehicle combination has a first motor train unit and at least one second motor train unit, each of which has a drive mechanism and a brake mechanism. Each of the brake mechanisms of the at least two motor train units has a plurality of brake units. In order to obtain a flexible utilization of the brake mechanism capacities of the coupled motor train units, a brake effect management system is formed in the coupled state. The management system is of a higher order than the brake mechanisms and is connected thereto. The management system is configured to distribute a braking effect onto the brake units of the at least two motor train units.Type: GrantFiled: December 19, 2014Date of Patent: October 30, 2018Assignee: Siemens AktiengesellschaftInventor: Manfred Wiesand

Patent number: 9707951Abstract: A rail vehicle braking device has at least one electrodynamic brake, which comprises a drive unit, which has at least one drive motor and a power supply unit for supplying the drive motor when the drive unit is in a traction mode. The rail vehicle braking device has at least two brake control units in order to increase the safety of the electrodynamic brake. In a first braking mode, a first brake control unit in an active state controls the power supply unit for providing a braking effect, a first brake effect monitoring unit and a switching unit, which serves to switch, depending on a brake effect parameter in the first braking mode, into a second braking mode, in which the second brake control unit in an active state controls the power supply unit for providing a brake effect.Type: GrantFiled: February 28, 2013Date of Patent: July 18, 2017Assignee: Siemens AktiengesellschaftInventors: Till Foerster, Stefan Hassler, Reiner Heilmann, Jean-Pascal Schwinn, Thorsten Stuetzle, Manfred Wiesand

Patent number: 9533668Abstract: A rail vehicle braking device has at least one first electrodynamic brake with a drive unit that includes at least one drive motor and a power supply unit for supplying the drive motor in a traction mode of the drive unit. A brake control unit controls, in a first brake mode, the respective power supply unit for providing a braking effect. In order to optimize the system with a fall-back measure in case of a braking effect loss in respect of the cause thereof, there is provided at least one sensor unit, which detects a braking effect parameter for the first braking mode of the brake. A monitoring device is assigned to the first brake. It is independent of the brake control unit and considers, in a first monitoring mode, the braking effect parameter for the introduction of a fall-back measure concerning the brake.Type: GrantFiled: February 28, 2013Date of Patent: January 3, 2017Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Till Foerster, Stefan Hassler, Reiner Heilmann, Jean-Pascal Schwinn, Thorsten Stützle, Manfred Wiesand

Patent number: 9079591Abstract: 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.Type: GrantFiled: March 21, 2012Date of Patent: July 14, 2015Assignee: Siemens AktiengesellschaftInventors: Steffen Jennek, Toni Schiffers, Manfred Wiesand

Patent number: 9067572Abstract: A brake arrangement of a railway vehicle includes an electrical brake device having an electronic brake controller and having an electro-pneumatic regulator with a pressure sensor. An emergency brake device has a pressure reducer in series with a valve device. A shuttle valve device is also present at a pneumatic output of the electrical pneumatic braking device and a pneumatic output of the emergency brake system and is connected at the inputs thereof. The output of the valve device is connected to a control valve device connected upstream of a brake cylinder. The brake arrangement can be a direct braking arrangement and can be converted in a simple manner to an indirect braking arrangement. The valve device is an electromagnetic emergency stop valve working according to the principle of de-energizing to close, and the pressure sensor of the electro-pneumatic regulator is connected to the output of the shuttle valve device.Type: GrantFiled: January 6, 2011Date of Patent: June 30, 2015Assignee: Siemens AktiengesellschaftInventors: Jens Peter Lichterfeld, Manfred Wiesand
