Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
The utility model is a kind of for heavy vehicle radar autobrake system, comprise air receiver 100, foot brake main brake valve 200, radar data processing system 300, front-wheel electromagnetic control air valve 211, trailing wheel electromagnetic control air valve 221, front-wheel pneumatic brake brake equipment 212, trailing wheel pneumatic brake brake equipment 222, described radar data processing system 300 is electrically connected with front-wheel electromagnetic control air valve 211 and trailing wheel electromagnetic control air valve 221 respectively, described air receiver 100 is communicated with foot brake main brake valve 200 by gas circuit A and gas circuit a respectively, be communicated with front-wheel electromagnetic control air valve 211 and trailing wheel electromagnetic control air valve 221 with gas circuit d by gas circuit D, described foot brake master brake cylinder 200 is communicated with 221 with gas circuit b with front-wheel electromagnetic control air valve 211 and trailing wheel electromagnetic control air valve by gas circuit B respectively, front-wheel electromagnetic control air valve 211 is connected with front-wheel pneumatic brake brake equipment 212 by gas circuit C, and trailing wheel electromagnetic control air valve 221 is connected with trailing wheel pneumatic brake brake equipment 222 by gas circuit c.On the described front-wheel electromagnetic control air valve 211 valve opening A1 is set, valve opening A2 and valve opening A3, the interface of gas circuit B, gas circuit C, gas circuit D and valve opening A1, valve opening A2 and valve opening A3 connect, the valve core movement of electromagnetic control air valve is controlled opening or closing of each valve opening, and then controls the connected sum closure of gas circuit B, gas circuit C, gas circuit D.On the described trailing wheel electromagnetic control air valve 221 valve opening a1 is set, valve opening a2 and valve opening a3, the interface of gas circuit b, gas circuit c, gas circuit d and valve opening a1, valve opening a2 and valve opening a3 connect, the valve core movement of electromagnetic control air valve is controlled opening or closing of each valve opening, and then controls the connected sum closure of gas circuit b, gas circuit c, gas circuit d.The normal operation of vehicle is lower, and gas circuit D is connected the gas circuit that gas is often arranged that connects storage tank with gas circuit d.Described front-wheel pneumatic brake brake equipment comprises front wheel brake relay valve or front wheel brake brake cylinder, and described trailing wheel pneumatic brake brake equipment comprises rear wheel brake relay valve or rear wheel brake brake cylinder.Described radar data processing system arranges sound prompt device.
The car load braking of heavy vehicle is controlled front wheel brake and rear wheel brake separately with two cover gas circuits respectively.During the automobile normal braking, by 200 controls of foot brake master brake cylinder, when the driver steps on brake pedal, Pneumatic pipe cleaner is crossed foot brake master brake cylinder 200 and is flowed to gas circuit B and gas circuit C, finish the front wheel brake process by gas circuit B and gas circuit C control front-wheel pneumatic brake brake equipment 212, when the driver lifts brake pedal, foot brake master brake cylinder 200 disconnects gas circuit between gas circuit A and gas circuit B, the gas circuit C, and the exhausr port of rapidly Pneumatic pipe cleaner among gas circuit B and the gas circuit C being crossed foot brake master brake cylinder 200 is discharged self-return releasing front wheel brake process.When the driver steps on brake pedal, Pneumatic pipe cleaner is crossed foot brake master brake cylinder 200 and is flowed to gas circuit b and gas circuit c, finish the trailing wheel braking procedure by gas circuit b and gas circuit c control trailing wheel pneumatic brake brake equipment 222, when the driver lifts brake pedal, foot brake master brake cylinder 200 disconnects gas circuit between gas circuit a and gas circuit b, the gas circuit c, and the exhausr port of rapidly Pneumatic pipe cleaner among gas circuit b and the gas circuit c being crossed foot brake master brake cylinder 200 is discharged self-return releasing trailing wheel braking procedure.
Vehicle is realized brake function automatically when vehicle runs into dangerous situation.When radar data processing system 300 is given front-wheel electromagnetic control air valve 211 and trailing wheel electromagnetic control air valve 221 power supply signal, the valve core movement of electric control air valve 211, close valve orifice A1, open valve opening A2 and valve opening A3, the Pneumatic pipe cleaner overcurrent among the gas circuit D is controlled front-wheel pneumatic brake brake equipment 212 in the gas circuit C finish self-stopping process.Simultaneously, the valve core movement of electric control air valve 221, close valve orifice a1 opens valve opening a2 and valve opening a3, the Pneumatic pipe cleaner overcurrent among the gas circuit d is controlled trailing wheel pneumatic brake brake equipment 222 in the gas circuit c finish self-stopping process.
When radar data processing system 300 interrupts for the power supply signal of front-wheel electromagnetic control air valve 211 and trailing wheel electromagnetic control air valve 221, the valve core movement of front-wheel electromagnetic control air valve 211, close valve orifice A3, open simultaneously valve opening A1, and simultaneously the gas in gas circuit C and the front-wheel pneumatic brake brake equipment 212 is flowed to gas circuit B and foot brake master brake cylinder 200 by valve opening A2 by valve opening A1.Deflation hole by foot brake master brake cylinder 200 is discharged gas automatically, finishes the overall process that front-wheel automatically terminates drag.The valve core movement of while trailing wheel electromagnetic control air valve 221, close valve orifice a3 opens valve opening a1 simultaneously, and simultaneously the gas in gas circuit c and the trailing wheel pneumatic brake brake equipment 222 is flowed to gas circuit b and foot brake master brake cylinder 200 by valve opening a2 by valve opening a1.Deflation hole by foot brake master brake cylinder 200 is discharged gas automatically, finishes the overall process that trailing wheel automatically terminates drag.
Can reach with relay or voltage transformer the optimum operating voltage of electric control valve when not conforming to electric control air valve required voltage such as radar data processing system output voltage.
When the speed of a motor vehicle during in the speed below 40 kilometers per hour, 300 of radar data processing systems are enabled sound prompt device, even vehicle and the place ahead obstacle can not start the electromagnetic control air valve yet in the danger range scope.Purpose is only sent false alarm and is braked for being more suitable for vehicle when high-speed road conditions or the need of work when the low speed road conditions are travelled and vehicle are met the place ahead highway barrier when highway is turned, can not make on the contrary driver's normal driving vehicle.
Because the car load braking of heavy wrecker truck and day bus and bus is controlled front wheel brake and rear wheel brake separately with two cover gas circuits respectively.But larger than the braking strength of front-wheel to the brake of car load design rear wheel brake in actual applications, if only can select automatically the control rear wheel brake with the automatic braking dual mode of controlling the car load wheel this to be installed when so self-actuating brake electric control air valve is selected in danger such as direction out of control vehicle yaw when front-wheel steering wheel brake dynamics is easy to too greatly cause the vehicle sudden stop in actual applications will be according to individual demand.
This radar autobrake system is applicable to heavy vehicle, and the institutes such as passenger vehicle and bus are useful on the installation of pneumatic brake braking principle vehicle and use.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
