Shown in Fig. 1, Fig. 2 and Fig. 3, this farm vehicle air-cut-off break device, comprise vehicle frame 18, trailing wheel 17, diesel engine 1 and belt pulley 2, diesel engine 1 is connected with belt pulley 2 by belt, belt pulley 2 is connected with inflation pump 3, pressure regulating valve 4, gas tank 5 successively, gas tank 5 is connected with brake activation valve 6, hand control valve (HCV) 7 respectively, brake pedal 12 is connected with brake activation valve 6 by brake push rod 11, brake activation valve 6 is connected with two air chambers 8 respectively by foot control rapid release valve 10, hand control valve (HCV) 7 is connected with two air chambers 8 respectively by manual rapid release valve 9, and air chamber 8 is connected with the brake drum 13 that is installed on trailing wheel 17.The brake facing 14 coordinating is with it installed in brake drum 13.
The principle of work of this farm vehicle air-cut-off break device is described below in conjunction with accompanying drawing and embodiment:
Embodiment 1
Farm vehicle in the process of moving, when chaufeur is stepped on brake pedal 12, brake push rod 11 tops are to brake activation valve 6, now the pressurized air of gas tank 5 is filled with two air chambers 8 through foot control rapid release valve 10, the diaphragm that promotes air chamber 8 promotes air chamber push rod 15 forward, and the eccentric cam bar 16 that makes to brake rotates an angle, and brake eccentric cam bar 16 when rotation struts brake facing 14, now brake facing 14 produces friction with brake drum 13, and brake drum 13 is stopped operating.Because brake drum 13 is fixedly installed in trailing wheel 17, and with trailing wheel 17 be synchronized rotation, in the time that brake drum 13 is stopped operating by friction force, trailing wheel 17 also stops operating simultaneously, reaches the effect of service brake.
When farm vehicle stops, chaufeur is pulled hand control valve (HCV) 7, now the pressurized air of gas tank 5 is filled with two air chambers 8 through manual rapid release valve 9, promoting air chamber 8 diaphragms promotes air chamber push rod 15 forward, the eccentric cam bar 16 that makes to brake rotates an angle, brake eccentric cam bar 16 when rotation struts brake facing 14, and now brake facing 14 produces friction with brake drum 13, and brake drum 13 cannot be rotated.Because brake drum 13 is fixedly installed in trailing wheel 17, and with trailing wheel 17 be synchronized rotation, in the time that brake drum 13 cannot be rotated by friction force, trailing wheel 17 also cannot rotate simultaneously, reaches the effect of braking during standstill.
