摘要： An energy storage wheel spin propulsion control system for detecting and correcting a spinning wheel situation so that the maximum available adhesion is utilized to the fullest extent in accelerating a railway vehicle while at the same time maximizing the use of the available processing time to permit an appropriate amount of time for diagnostic purposes. The primary data used to form the logic inputs is derived from the axle rate signals which are fed to spin energy storage value threshold and difference comparison sensors. The spin energy storage value and difference comparison sensors supply logical inputs in spin energy threshold, dissipation threshold and optimization threshold sensors and spin rate difference sum sensor, respectively, which, in turn, supply logic inputs to spin enable timer and spin enable sensors and a spin control logic output sensor. A slip-spin output determination sensor receives logic signals from a power-brake signal circuit and command signal from the spin control logic outer sensor and a slip interface circuit to cause the production of a full requested, reduce and/or hold tractive effort command.

摘要： An electronic load weigh device is used with a railcar truck control unit. A relay valve provides to a brake cylinder a pressure proportional to the pressure impinging upon its control port. A first feedback signal is indicative of the pressure at the control port. A second feedback signal is indicative of the load borne by the truck. A pressure switch opens when pressure within a trainline changes to a level indicative of an emergency. By controlling the opening and closing of application and release magnet valves, a controller controls the pressure impinging on the control port and thereby service braking of the wheels of the truck. The load weigh device includes (i) circuitry for electronically compensating for the load during braking and (ii) a mechanism for granting the circuitry exclusive control over the magnet valves. Should such emergency occur, the mechanism responds to such emergency by disconnecting the controller from the magnet valves. This gives the circuitry exclusive control over the magnet valves. The circuitry compensates for the load borne by the truck during emergency braking by selectively opening and closing the magnet valves, according to predetermined criteria using the feedback signals, thereby controlling the magnitude of the pressure impinging upon the control port. Absent such emergency, the mechanism responds to such absence by connecting the controller to the magnet valves whereby such service braking on the truck is normally controlled, yet the circuitry is still enabled to compensate for the load during such service braking.

摘要： The time reset safety timer circuit eliminates approximately half of the external interfaces of the prior art safety timers. The prior art safety timers depend on vehicle axle speeds, brake indications, and/or trainline signals to initiate a safety timer reset. The time reset safety timer circuit in the present invention uses only internal information to initiate a safety timer reset. This simplifies the circuitry of the time reset safety timer circuit, which improves the reliability.

摘要： A universal unit controls the brakes of a truck of a rail vehicle. The unit includes a service valve, an emergency valve, a variable load relay valve, a release valve, a local control device, a solenoid driver device and a brake assurance device. The service valve when opened provides a first control pressure. The emergency valve when opened provides a second control pressure. In response the control pressures, the variable valve provides to the brake cylinder a load compensated pressure proportional to air spring pressure. The brakes then apply to the wheels of the truck a force that accounts for the load borne by the rail vehicle. The release valve when opened prevents the variable valve from providing the load compensated pressure. The local control device controls the control pressures according to a brake force command signal and a control pressure feedback signal. The solenoid device operates the valves in response to valve command signals received from the local control device. The brake assurance device operates in a standby mode in which the local control device controls the release and emergency valves via the solenoid device or in an intervention mode in which it does not thereby assuring that the release and emergency valves open. This enables the variable valve to provide the brake cylinder with the load compensated pressure and therefore apply the brakes. The brake assurance device assumes the intervention mode in response to a loss of power or to a predetermined set of conditions.
摘要翻译：通用单元控制轨道车辆的卡车的制动。该单元包括维修阀，应急阀，可变负载继电阀，释放阀，本地控制装置，螺线管驱动器装置和制动保证装置。打开时的维修阀提供第一控制压力。打开时的紧急阀提供第二控制压力。响应于控制压力，可变阀向制动缸提供与空气弹簧压力成比例的负载补偿压力。然后制动器将卡车的轮子应用于考虑轨道车辆所承载的载荷的力。打开时的释放阀阻止可变阀提供负载补偿压力。本地控制装置根据制动力指令信号和控制压力反馈信号控制控制压力。螺线管装置响应于从本地控制装置接收到的阀命令信号来操作阀。制动器保护装置在待机模式下工作，其中本地控制装置经由螺线管装置控制释放和应急阀，或者在干预模式下，其不能确保释放和紧急阀打开。这使得可变阀门能够向制动缸提供负载补偿压力，因此应用制动器。制动保证装置采取干预方式来响应功率损失或预定的一组条件。

摘要： A brake assurance module assures braking on at least one truck. It includes a summer, a level circuit, a delay circuit, an emergency driver, a valve driver and a timer circuit. The summer sums friction and dynamic braking signals into a total braking signal. The level circuit generates a threshold signal when the total braking signal exceeds a threshold. The delay circuit generates a level signal after having received the threshold signal throughout a preset time. When the emergency driver receives an emergency signal, it conveys a detect signal. The valve driver controls contacts each in series within a control line used to energize a valve whose operation is normally controlled by the brake control system. The valve driver when activated closes the contacts thereby permitting the system to control the valves. When deactivated, the valve driver opens them thereby preventing the system from controlling the valves. The timer circuit has set, trigger and reset inputs. When the set input receives the level and zero speed signals simultaneously, the timer circuit activates the valve driver thereby placing the module in a standby mode. The timer circuit monitors the trigger input for the detect and full service signals in response to which it becomes enabled. If the reset input receives the level signal within a predetermined time after the timer circuit enables then the timer circuit resets thereby keeping the module in the standby mode. Otherwise, the timer circuit deactivates the valve driver thereby placing the module in an intervention mode.
