    • The present invention is predicated upon the use of an apparatus that is engageable with a hand brake assembly which will automatically apply at least one brake means secured to a railway vehicle with such hand brake assembly. The apparatus of the invention comprises an operating means having at least a portion thereof engageable with at least one gear of a gear assembly disposed in a housing member of the hand brake assembly for operating such gear assembly. A source of fluid pressure is connected to operating means for periodically supplying a predetermined pressure to such operating means. A control means is connected to the source of the fluid pressure for initiating the supply of such predetermined pressure to the operating means. A further control means is connected to the source of the fluid pressure for regulating the supply of such predetermined pressure to the operating means thereby causing an automatic application of such brake means by the hand brake assembly. An additional control means is connected to the source of the fluid pressure for stopping an automatic application of such brake means in case of the emergency or a reversal of the unintented activation.
    • 本发明基于使用可与手制动器组件接合的装置,该手动制动组件将使用这种手制动器组件自动地应用固定到铁路车辆的至少一个制动装置。 本发明的装置包括操作装置,该操作装置具有至少一部分,该至少一部分可与设置在手制动器组件的壳体构件中的齿轮组件的至少一个齿轮接合,用于操作该齿轮组件。 流体压力源连接到用于周期性地向这种操作装置提供预定压力的操作装置。 控制装置连接到流体压力源,以启动向操作装置提供这样的预定压力。 另外的控制装置连接到流体压力源,用于调节对操作装置的这种预定压力的供应,从而通过手制动组件自动应用这种制动装置。 连接到流体压力源的另外的控制装置用于在紧急情况下或在无意激活的反转的情况下停止自动应用这种制动装置。

    • A brake apply control system for a vehicle. The control system has a selectively operable mechanical brake apply portion and a selectively operable hydraulic brake apply portion. The mechanical brake apply portion includes an operator linkage for connecting the operator with a mechanical brake apply mechanism and a hydraulic piston and valve combination for providing a hydraulic feedback force to the operator. The hydraulic brake apply portion includes a source of hydraulic pressure, a brake apply valve for supplying a selective brake signal of variable intensity in response to operator input, a conduit system which connects the source of hydraulic pressure to the hydraulic piston and valve combination and which communicates the brake signal to the hydraulic piston and valve combination. The hydraulic piston and valve combination responds not only to the source of hydraulic pressure to provide a first feedback force to the operator, but also to the brake signal for providing a second feedback force to the operator that is proportional to the intensity of the brake signal.
    • 一种用于车辆的制动应用控制系统。 控制系统具有选择性可操作的机械制动施加部分和可选择性地操作的液压制动施加部分。 机械制动施加部分包括用于将操作者连接到机械制动施加机构的操作者联动装置和用于向操作者提供液压反馈力的液压活塞和阀组合。 液压制动施加部分包括液压源,用于响应于操作者输入提供可变强度的选择性制动信号的制动施加阀,将液压源连接到液压活塞和阀组合的管道系统,以及哪个 将制动信号传递给液压活塞和阀组合。 液压活塞和阀门组合不仅响应于液压源,以向操作者提供第一反馈力,而且响应于制动信号,以向操作者提供与制动信号的强度成比例的第二反馈力 。
