Air System and Brakes
制动系统由气压驱动。 制动器设在每侧后轮上。 空气压缩机向气罐输送气压。 这些空气通过气罐的两个单向阀输送。 止回阀只许气体单向通过。 气罐有两个安全阀和两个排放阀。
气压从气罐流向行车制动器的空气控制阀。 气压还从空气控制阀流向停车制动器。
气压从空气控制阀流向行车制动器,以便启用行车制动器。 行车制动器是由独立的回路带动。 独立回路各自控制机器的右侧和机器的左侧。 气罐能提供足够的气压,以致即使发动机和空气压缩机停止后,行车制动器还可以制动五次。 万一其中一支空气管路失灵或其中一支回路发生故障,气罐的另一部分仍然储有气压。 此气压将用于接合一个串联驱动装置上的行车制动器。
