Abstract
The utility model belongs to the teaching experimental apparatus field, relating to an automobile professional hydraulic brake system teaching experimental apparatus and more specifically referring to a vacuum supercharged hydraulic brake apparatus operating principle experiment table. According to the utility model, a motor 11 drives a wheel 10 to rotate; a vacuum pump 9 simulates an engine inlet manifold to supply vacuum for a vacuum tank 7; high pressure brake fluid pressure generated by a brake main cylinder 3 and hydraulic oil pressure sent by an auxiliary cylinder are detected and displayed by a pressure gage 4. A vacuum meter 6 detects and displays change of vacuum degree. The vacuum supercharged hydraulic brake apparatus operating principle experiment table possesses a reasonable design, stable performance, strong practicality, a simple structure, cheap price, etc., can substantially raise teaching effects and can be widely applied on automobile professional teaching and experiment.
Description
Technical field
The utility model belongs to education experiment utensil field, relates to automobile major brake fluid system experiment device for teaching, is specifically related to a kind of experiment table that shows vacuum boosting formula brake actuator principle of work.
Background technology
Behind the automobile high-speed, major part all is equipped with the vacuum augmentor on the automobile of employing hydraulic braking, improves brake fluid pressure, to increase braking moment, alleviates driver's operation fatigue, improves the reliability of braking at present.Vacuum boosting formula commonly used is the augmentor of commonly using.But, the work of supercharger will mutually combine with vacuum tightness, the pedal travel of engine, principle is comparatively abstruse, the trouble spot is also many, in the teaching of automobile major, teachers and students are generally reflected religion, are learned relatively difficulty, therefore how in teaching with its visual in image showing, become the key of improving the quality of teaching.
Although unit development brake system experiment tablees such as many domestic teaching aids manufacturing enterprise, schools, the ubiquity price is high, complex operation, and the shortcoming such as it is not obvious that principle shows, failure rate is high, and the dynamic demonstration effect is poor has affected teaching efficiency.Above-described problem has to be solved, and this just need to have a kind of new, device more intuitively, and its principle of work is demonstrated.Be Teaching Service better.
Summary of the invention
The purpose of this utility model is to address the above problem, provide a kind of simple in structure, cost is low, the experiment table of easy operating is showed the course of work of vacuum boosting brake system in Motor Vehicle Braking Procedure intuitively by the variation of pressure, and the pressurization of supercharger.Also can utilize this experiment table to test and dependent failure diagnosis and get rid of teaching, the student can directly be seen action effect with the brake system of supercharging improve teaching efficiency.
Specifically be achieved through the following technical solutions:
Vacuum boosting formula hydraulic brake system principle of work experiment table described in the utility model mainly is comprised of power system, power supply device, vacuum blower, control device, Displaying Meter etc.
Power system comprises a motor, an automobile axle.
Power supply device comprises the original papers such as vacuum pump, vacuum tank, vacuum check valve, and vacuum pump substitutes motor intake manifold, for supercharger provides vacuum source.
Control device has: master cylinder, brake pedal, wheel drag, oil pipe etc., by the control brake pedal, finish the braking task by the back axle wheel drag.
Displaying Meter has oil pressure indicator gauge and pressure vacuum gauge.Oil pressure gauge shows the oil pressure of master cylinder and working connection.Pressure in the servo air chamber of pressure vacuum gauge detection display and the operation valve changes.
Advantage of the present utility model:
1, substitutes motor intake manifold with vacuum pump and supply with vacuum tightness, simple, environmental protection.
2, show the variation of oil pressure, air pressure with tensimeter, be convenient to principle of work, the course of work of observation of students, understanding system, teaching efficiency is good.
Description of drawings
Fig. 1 is the layout synoptic diagram of vacuum boosting formula hydraulic brake system principle of work experiment table described in the utility model.
Embodiment
The 1-wheel cylinder; The 2-brake pedal; 3 master cylinders; 4-brake fluid pressure table; The 5-vacuum blower; The 6-vacuum meter; The 7-vacuum tank.The 8-vacuum check valve; The 9-vacuum pump; The 10-wheel; The 11-motor
Below in conjunction with implementing accompanying drawing the utility model is described further.As shown in Figure 1, experiment table described in the utility model drives wheel 10 by motor 11 and rotates, vacuum pump 9 simulated engine inlet manifold provide vacuum to vacuum tank 7, when stepping on brake pedal 2, the high hydraulic brake fluid that master cylinder 3 produces is when pipeline enters the auxiliary cylinders of supercharger 5, through tensimeter 4 detected pressures and demonstration, a high hydraulic brake fluid part enters in the wheel cylinder 1 as motivator, the operation valve of another part input supercharger 5 is as controlled pressure, starting operation valve makes the thrust of servo vacuum air chamber generation on the piston of auxiliary cylinders, make the oil pressure seen off far above the pressure of master cylinder, detect and demonstration through oil pressure gauge this moment, vacuum meter 6 is contained in vacuum check valve 8 to the passage of vacuum tank 7 and on the operation valve, detect and show the variation of vacuum tightness with this, can demonstrate by closing and open switch on the vacuum tank 7 effect of power-assisted during experiment.Can utilize vacuum meter 6 and switch to carry out the bubble-tight check practice of supercharger.Can utilize the oil-tightness of oil pressure gauge and switch check system.
The utlity model has reasonable in design, stable performance, practical, simple in structure, the characteristics such as low price can significantly improve teaching efficiency, can be widely used in teaching and the experiment of automobile major.
