    摘要： An auxiliary air brake system is provided for a mobile vehicle which has a drive selector having reverse and other positions and which has a main air brake system which includes a plurality of compressed air tanks, main conduit including a foot brake line and a hand brake line for connecting at least one of the tanks to wheel brake chambers, and air control valves in the main conduit for controlling air pressure at the wheel brake chambers. The auxiliary air brake system includes a first additional air control valve controlled by the drive selector, a detector mounted at the rear of the vehicle positioned to be actuated by contact with an external object during reverse movement of the vehicle, a second additional non-electrically actuated air control valve actuable in response to actuation of the detector member and additional conduit which connects the first and second additional air control valves to control the pressure at the brake wheel chambers when the detector member is in its actuated condition and the drive selector is in reverse. The second non-electrically actuated air control valve has a spring biased operating plunger having at one end a roller which is contacted by the detector member to depress the plunger thereby to connect pressurized air to the auxiliary braking system.

    摘要翻译： 为具有倒档等位置的驱动选择器的移动式车辆提供辅助空气制动系统，其具有主空气制动系统，该主空气制动系统包括多个压缩空气箱，主导管包括脚制动线和手制动线 用于将至少一个罐连接到车轮制动室，以及用于控制车轮制动室处的空气压力的主管道中的空气控制阀。 辅助空气制动系统包括由驱动选择器控制的第一附加空气控制阀，安装在车辆后部的检测器，其定位成通过在车辆的反向运动期间与外部物体接触而致动，第二附加非电气 致动的空气控制阀响应于检测器构件的致动而致动，并且当检测器构件处于其致动状态时连接第一和第二附加空气控制阀以控制制动轮室处的压力并且驱动选择器处于 相反。 第二非电致动的空气控制阀具有弹簧偏压的操作柱塞，其一端具有与检测器构件接触以压下柱塞的辊，从而将加压空气连接到辅助制动系统。
