Abstract
The present invention is instant detection system for vehicle brake and belongs to the field of automobile part manufacturing technology. The present invention features that all the signals from the wheel displacement sensing system, the pressure sensing system and oil leakage sensing system are fed to the data processing system to compare with the preset parameters and the output signal after comparison is fed to display and alarm system. The present invention has the advantage of the accurate and simple detection of the automatic braking system to detect hidden trouble and to ensure traffic safety.
Description
Technical field:
The invention belongs to automobile component manufacturing technology field.
Background technology:
The brake system of automobile is most important to traffic safety, the reason of traffic accident generation has more than 70% bad relevant with brake according to statistics, if in time investigate thoroughly the intact degree of brake system before realizing driving a vehicle at every turn, then can improve traffic safety greatly, reduce the incidence of traffic accident.At present, the driver is to the detection mode of brake and drive system for vehicle with tow, all adopt to treat that car travels and step on sudden stop when reaching certain speed per hour, then according to tire on the road surface brake impression length and have directionless skew to judge whether the situation of brake system good; But this detection mode is bothered by road surface situation restriction and process, and basic unmanned warp this method commonly used detects brake system causes the brake system problem in time to find, traffic safety hidden danger is difficult to eliminate.
Technical matters to be solved by this invention is:
Provide a kind of vehicle under dead ship condition, need not the instant checking system of braking automobile that the travelling brake process can detect brake system.
Technical scheme of the present invention is as follows:
Brake system normally whether depend primarily on two aspects, one is whether the wheel cylinder of four wheels intact, the 2nd, whether the wearing and tearing thickness of brake facing surpasses safety requirements.
Import the acquired signal of the displacement sensing system of each wheel, pressure capsule system, leakage of oil sensor-based system into data processing system, and with the preset parameter contrast of data processing system, again the processing signals after the contrast is exported to the display alarm system.
The variation in thickness signal that displacement (variation in thickness) sensor acquisition head is gathered is sent into microprocessor by signal processor unit and analogue to digital conversion (A/D) device; Pressure sensor is connected with wheel cylinder with oil leakage sensor, the piston of measuring wheel cylinder by pressure sensor ejects pressure signal and sends into microprocessor through the compensation multiplying arrangement, send into microprocessor by the moisture signal that humidity (leakage of oil) sensor is measured through oscillator and A and D converter, microprocessor with above-mentioned three kinds of signals and preset parameter relatively after, the processing signals is relatively sent into output interface output shows signal and suggestion voice.
Displacement (variation in thickness) sensor acquisition head is arranged on brake block friction material variation in thickness position;
The pressure sensor collection head is arranged on the stressed iron of each brake facing and the bearing surface that piston contacts;
Humidity (leakage of oil) sensor acquisition head is arranged on each wheel brake wheel cylinder oil sealing outside end face.
The invention has the beneficial effects as follows:
Normally whether the brake system that can detect automobile has simply exactly immediately fundamentally realized timely discovery brake system hidden danger, effectively reduces the traffic accident incidence, has improved driver and conductor's traffic safety guarantee to greatest extent.

The specific embodiment:
The piston of wheel cylinder is ejected parameters such as pressure, brake block friction material safe thickness, wheel cylinder leakage of oil variation to be preset in the microprocessor earlier, under dead ship condition, open the instant checking system of braking automobile and connect switch, step on brake pedal, each wheel sensor collection head is sent into the real-time signal of gathering in the microprocessor, and with preset parameter relatively, the signal output after the comparison process is sent into and is shown and normally whether voice device points out brake system.
