Description
Technical field
The utility model relates to a kind of brake system of car, especially relates to a kind of Vehicle Electronic Control air braking systems.
Background technology
Along with increasing of domestic high-grade highway, large-tonnage, long wheelbase goods carrying vehicle and trailer with obvious ton-kilomiter cost advantage are also increasing year by year, and the major traffic accidents that bring simultaneously are also more and more outstanding.Divide folding according to national departments concerned, cause for braking time lag more than having three one-tenth in the annual ten hundreds of major traffic accidents of China.According to Zhejiang Province's express highway Traffic Warden Subteam Shanghai-Hangzhou-Ningbo traffic accidents statistics is shown " superimposed trailer more than three is the most obvious to the harmfulness of traffic safety ".Standard GB 12676 regulation, from October in 2003 M3 class on the 1st motorcoach, N3 class goods carrying vehicle and O4 class trailer must install and meet a class anti-skid brake system (ABS) and an automatic clearance adjuster of stipulating among the GB13594.But practice shows, air brakes vehicles for long wheelbase, still can not guarantee traffic safety preferably even ABS anti-skid brake system and automatic clearance adjuster have been installed, to the long wheelbase vehicle of running at high speed, the reaction time hysteresis problem of compression air brake remains subject matter.
Summary of the invention
The purpose of this utility model is to reflect at the compression air brake of above-mentioned long wheelbase vehicle the problem of time lag, and a kind of Vehicle Electronic Control air braking systems that can make each wheel synchronous braking is provided.
The utility model is the Vehicle Electronic Control air braking systems, and for reaching this purpose, the utility model has mainly adopted following technical scheme to realize.The utility model is made up of brake valve of car, brake valve of car by brake piping respectively be located at the front truck sedan-chair on compressed air brake cylinder and the brake application by spring air chamber of being located on the car sedan-chair of back be connected.Described brake valve of car is provided with the Hall-type pedal and passs on angle transducer, and connects electronic controller (ECU).Described electronic controller (ECU) mainly is made up of incoming signal treatment circuit and output driving circuit.The output port of electronic controller (ECU) is connected at the solenoid-operated proportional relay valve on the forward and backward car sedan-chair respectively, this valve has two air extractor ducts at least, control the braking of car sedan-chair left and right wheels respectively, the solenoid-operated proportional relay valve also is respectively equipped with air receiver, links to each other with Air compressor.The utility model electronic controller (ECU) also can cooperate with the ABS anti-skid brake system that is provided with on the car sedan-chair.
The utility model compared with prior art has following obvious advantage and good effect.(1), the utility model is a kind of brand new Pneumatic braking system, it has solved the problem of the intrinsic response lag of Pneumatic braking system to greatest extent, even the synchronous braking that also can realize each wheel to the independent trailer and the superimposed trailer of long wheelbase.This system adopts redundancy principle to firmly believe the position of brake pedal with an angular-motion transducer, and produce an electric signal that changes with the pedal position ratio, this electric signal is control power amplifiers after the shaping of filtering letter, final drive installation near wheel integrated air pressure relay valve and the air pressure adjustment module of electromagnetic proportional valve, this design is got the transmission of having changed air pressure with the speed of transmission of electricity, thereby has solved the problem that the existing Pneumatic braking system reaction time lags behind.Even the utility model also can be finished the conventional brake function under the partly entirely ineffective situation of electron steering, can find fault by self check simultaneously, and adopt the flicker code to inform chaufeur, carefully drive also reparation as early as possible.(2), the utility model is simple and easy to do, do not need the automobile brake pipeline is transformed, and on brake system basis now, adds the brake pedal rotary angle transmitter and changes the air pressure adjustment module and can finish, and has that cost is low, the obvious results characteristics.(3), improve insensitivity.Present many experienced driver adopt by the back, in, front axle artificially amplifies the method for brake clearance successively, but obviously strengthened stopping distance, and is abnormally dangerous under fully loaded high speed traveling condition.The Vehicle Electronic Control air braking systems is the Perfected process that addresses this problem, cooperate ABS anti-skid brake system and automatic clearance adjuster to use, the ABS control program is the master control thresholding with wheel deceleration/decel and slip rate, not only can increase traffic safety, and can realize the braking impulsive force of trailer connection place minimum, the pulsation-free braking procedure is with the safety that guarantees to convey goods.
The utility model is applicable to passenger vehicle, truck and trailer.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
