    • An emergency brake system (10) comprises first and second fluid communication paths (20) and (22) which provide fluid communication between a brake (18) and a hydraulic fluid tank (24). A first valve is provided in the first path (20) to vary pressure in the brake line (26) to a pressure P 1 enabling the brake to apply a braking torque of T 1 and a second valve (30) is provided in the path (22) to vary brake line pressure to a pressure P 2 enabling the brake (18) to apply a braking torque of T 2 where T 2 > T 1 . The system (10) senses the speed of a machine to which the brake (18) is coupled. Depending on the sensed speed of the machine when the emergency brake (18) is applied the system (10) will open one or both of the paths to control the braking torque applied by the brake (18).
    • 紧急制动系统(10)包括在制动器(18)和液压油箱(24​​)之间提供流体连通的第一和第二流体连通路径(20)和(22)。 第一阀设置在第一路径(20)中,以将制动管路(26)中的压力改变为压力P1,使得制动器施加T1的制动转矩,并且在路径(22)中设置第二阀门(30) )将制动管路压力改变为使得制动器(18)能够施加T2的制动转矩T2(T2)> T1的压力P2。 系统(10)感测制动器(18)联接到的机器的速度。 根据当紧急制动器(18)被施加时感测到的机器的速度,系统(10)将打开一个或两个路径以控制由制动器(18)施加的制动转矩。
