Abstract
The invention relates to an electrical control pneumatic brake device with self diagnosis for a flat transporter, belonging to the field of flat transporters. An electronic brake pedal is arranged; the electrical control pneumatic brake device is characterized in that the electronic brake pedal is electrically connected to a controller; the controller outputs a brake signal to control actions of a proportional pressure-reducing valve which is connected to a relay valve; an output port of the relay valve is communicated with a pipeline of a brake air chamber; a pressure sensor is arranged at the brake air chamber; the pressure sensor is electrically connected to the controller; after being connected to a parking brake solenoid valve in parallel, an upper end of a manual air valve is connected to an air source, and the lower end of the manual air valve is connected to the relay valve by a dual-way check valve. The structure of the electrical control pneumatic brake device is simple; the controller is used for closed-loop controlling and real-time monitoring of a brake system; and the reliability of the brake system is improved in aspects of self-detection during whole vehicle start, real-time monitoring and performance monitoring during running and emergency braking and the like.
Description
Technical field
The present invention relates to the flat bed transport vehicle field,, be used for the flat bed transport vehicle braking especially with the automatically controlled air braking system of selfdiagnosis.
Background technology
As everyone knows, flat bed transport vehicle is a kind of large-scale transportation device, can finish the carrying of volume, goods that weight is bigger, can be used as the road transport of main equipment (goods), the transhipment of the commentaries on classics preface transportation of shipbuilding yard body section and steel plant's steel plate, steel pipe.The flat bed transport vehicle load carrying ability is very big, and general at full load complete vehicle weight all surpasses 320 tons, and inertia is very big, so require the brake system must be very reliable.Existing flat bed transport vehicle brake system reliability is relatively poor, can't find the potential safety hazard of brake system in advance, and can not monitor in real time and emergency brake.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides the automatically controlled Pneumatic braking device of a kind of flat bed transport vehicle with the band selfdiagnosis, adopted controller that brake system has been carried out closed loop control and real time monitoring, the self check when car load starts fully improves the reliability of brake system to several respects such as operating real-time monitoring and performance monitoring, emergency brakes.
The technical solution adopted for the present invention to solve the technical problems is: a kind of flat bed transport vehicle automatically controlled Pneumatic braking device of band selfdiagnosis, be provided with electronic brake pedal, it is characterized in that electronic brake pedal is electrically connected with controller, the action of controller output speed-slackening signal control ratio reducing valve, proportional pressure-reducing valve is connected with relay valve, the delivery port of relay valve is connected with the pipeline of compressed air brake cylinder, the compressed air brake cylinder place is provided with pressure sensor, pressure sensor is electrically connected with controller, manually air valve and termination source of the gas on it after the braking during standstill electromagnetic valve is in parallel, its lower end connects relay valve through the bilateral check valve.
The invention has the beneficial effects as follows, simple in structure, adopted controller that brake system has been carried out closed loop control and real time monitoring, the self check when car load starts fully improves the reliability of brake system to several respects such as operating real-time monitoring and performance monitoring, emergency brakes.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1, structural representation of the present invention.
1. electronic brake pedals among the figure, 2. pressure sensor, 3. controller, 4. proportional pressure-reducing valve, 5. manually air valve, 6. relay valve, 7. compressed air brake cylinder, 8. bilateral check valve, 9. braking during standstill electromagnetic valve.
The specific embodiment
In Fig. 1, the present invention is provided with electronic brake pedal 1, operator's compartment before and after electronic brake pedal 1 is arranged on, electronic brake pedal 1 is electrically connected with controller 3,4 actions of controller 3 output speed-slackening signal control ratio reducing valves, proportional pressure-reducing valve 4 is connected with relay valve 6, the delivery port of relay valve 6 is connected with the pipeline of compressed air brake cylinder 7, compressed air brake cylinder 7 places are provided with pressure sensor 2, pressure sensor 2 is electrically connected with controller 3, manual air valve 5 and braking during standstill electromagnetic valve 9 termination source of the gas on it afterwards in parallel, its lower end connects relay valve 6 through bilateral check valve 8.
After car load of the present invention powered on, control system was carried out self check to brake system, and air pressure during promptly by pressure sensor 2 brake monitoring system different conditions and the normal data contrast that is stored in the controller 2 judge whether normal.And passing through 9 energisings of controller 3 control braking during standstill electromagnetic valves, outage, detected pressures sensor 2 is exported and is judged with the normal data contrast whether emergency brake system is normal simultaneously.And check in the operation process whether the brake system failure record was arranged last time, working properly as there not being the explanation brake system, operation drops into operation.In the driving process, electronic brake pedal 1 is accepted the brake operating of chaufeur, output and the corresponding curtage signal of electronic brake pedal 1 stroke, this electric signal transmission is to controller 3, controller 3 software program for execution are calculated the electric signal of input, the actv. brake control signal is outputed to proportional pressure-reducing valve 4, the control of braking electric signal is converted to the air pressure signal of corresponding size by proportional pressure-reducing valve 4, guide's air pressure of braking that Here it is, braking guide air pressure enters the service brake control mouth of relay valve 6, control relay valve 6 output braking pressures are finished service brake control to the service brake air pressure input port of compressed air brake cylinder 7.The pressure sensor 2 that is arranged at relay valve 6 inlets is transformed into electric signal with brake pressure signal and is sent to controller 3.The error of the output signal of controller 3 real-time relatively electronic brake pedals 1 and the output signal of pressure sensor 2 is to judge the whether working properly of brake system.If the pressure of finding relay valve 6 input ports is much smaller than the pairing correct pressure in electronic brake pedal 1 position this moment, then controller 3 thinks that service brake lost efficacy, this moment, controller 3 was given braking during standstill relay valve 9 outages (driving states braking during standstill relay valve 9 always), this moment, brake system relied on the spring force braking, and car load is slowed down until parking.
