Description

Efficient braking controller for vehicle

The utility model belongs to the brake system of car field, particularly a kind of efficient automobile brake controller.

Present standard anti-lock brake system (ABS system) has 3 chief components: i.e. wheel speed sensors, brake regulator and an electronic control unit (ECU).Late nineteen eighties West Germany releases first generation electronic type ABS system, but this valuable product (amounting to more than 6000 yuan of Renminbi) is so use only for head of State and state guest's vehicle.In addition, electronic type ABS system only works when wheel locking, can make the braking of vehicle straight line, but in most of the cases, it can not shorten the stopping distance of wheel.Stopping distance surpasses more than 5 percent.The same period, the U.S. released mechanical type ABS of new generation system, and mechanical type ABS system has many good qualities than electronic type ABS.It can shorten stopping distance; System's generation effect all automatically under any circumstance; Increase braking function; Be applicable to all hydraulic formula brake system vehicle etc.But the technical index coefficient of the anti-lock transformation point that mechanical type ABS system produced in USA is controlled is the comprehensive parameters of selecting for use, and is can not mode, and when therefore using on various vehicle, effect is subjected to influence in various degree.The early 1990s the Japan several multi-form ABS system that mechano-electronic combines that releases one after another again.But, still only in Pullman saloon or expensive vehicle, adopt at present because price is higher.Though U.S. product mechanical type ABS system is lower than electronic type ABS system price, but every cover is still amounted to 3000 yuan of Renminbi, although domestic vehicle need to be eager the technical products of this raising deceleration and stopping performance, but be difficult to accept this price, and the U.S. produces the ABS system to homemade brake pump coupling very, and the brake pedal feel that the back chaufeur is installed is bad.(feeling that promptly pedal " too soft " psychology is difficult to bear, and always thinks that braking mode is bad) so this technology are gone back not seen widespread use at home.

From foreign data as can be known, in the traffic accident, because of moist (raining) road surface situation (accounting for 30%) with all relevant with sideslip because of ice and snow road situation (70%-80%), and have 50% sideslip accident to cause by braking.250 the grave accident writing charts in domestic certain city are bright: have 40% to be that the emergency braking skid causes owing to " stopping distance is excessive ".Find out that thus braking deviation and stopping distance are excessive significant to traffic safety.

The purpose of this utility model provides and a kind ofly can overcome braking deviation and the excessive efficient automobile brake controller of stopping distance.

The utility model is achieved through the following technical solutions:

In principle, drg is a friction gear.On machinery and operating principle, it approximately plays 50 to 60 percent.All multifactor wheel hub/video discs that makes such as heat and other reason such as size produce slight bending and mistake circle, and the metal surface has increased the sags and crests of a lot of injustice.At glancing impact, the protruding point on brake strap/brake shoe and the wheel hub/video disc forms and contact, so in brake piping, brake-pressure rises rapidly, when forming when contacting with the position of concave surface, brake fluid pressure is decline rapidly again.

Therefore, when pressing down with the foot the slipper brake, brake strap/brake lining piece correspondingly contacts the part of protrusion, thereby has increased fluid pressure in the system, causes and produces friction, heat and loss extremely between brake strap/wheel hub and video disc/brake shoe.Braking liquid can not continue to be compressed this moment, and also can not return by pipeline.Therefore, unless the brake fluid pressure in the brake piping increase along with the uneven of contact surface or reduce, otherwise, brake strap/brake shoe can not be fully by going up the position of protruding.It is exactly the dead point that brake strap/wheel hub contacts at the position of protruding with video disc/brake shoe, because there is higher pressure to produce here, and can bring excessive friction, finally cause wheel locked prematurely, yet vehicle is when walking, four wheels of car produce above-mentioned situation again can never be consistent average, and therefore on same position, the glancing impact wheel just can get out of hand.

We are according to " expansion technique " and " the equal public principle of hydraulic pressure ", in controller, be provided with plug 9, in controller, when brake fluid pressure during greater than a certain transformation point, plug will overcome and give the pressure that fills air and move to expansion chamber 11 directions, thereby brake-pressure is weakened; When brake fluid pressure during less than a certain critical-point pressure, the pressurized air of expansion chamber pushes back plug again, brake-pressure is improved, making brake-pressure produce pulsed thus changes, thereby make between brake strap and the brake wheel and when concavo-convex the contact, all can produce self-regulating equalization pressure, make brake strap/brake shoe/brake wheel to go up and protrude the position with the mistake circle, recessed heavy position also changes generation batch (-type) contact (pulsation) with pressure simultaneously by last when the concavo-convex contact point of brake strap and brake wheel contacts.

Now engage description of drawings embodiment (Fig. 1):

This efficient automobile brake controller is made up of shell upper body 1, aie escape valve 2, plug sleeve 3, switching mouth 4, seal ring 5.8, shell lower body 6, stick harness 7, plug 9, inflation control cock 10 and expansive force spring 12.

Entire controller is connected with master cylinder distribution pipe interface mouth in the former brake system of car by switching mouth 4, the mouth rear portion that is about to transfer is connected to the braking of former car and is in charge of, can make the braking liquid in the former brake system of car enter chamber within the plug 9 thus by plug sleeve 3 and stick harness 7, when fluid pressure in the brake system during greater than a certain critical value, the pressure that produces in plug sleeve, stick harness and the plug forces plug to overcome to give the effect of filling air pressure and expansive force spring in the chamber in the air expansion chamber 11 and expands (as the figure dotted line position) to the outside, so that pipeline inner pressure is weakened on request.Otherwise when braking fluid pressure during less than a certain critical value, expansion chamber inner air pressure and expansive force spring be again with the plug pushed home, thereby hydraulic coupling is replenished, and plays the effect of automatically regulating with this reciprocation cycle.

By dress this when device by the aie escape valve 2 last air of getting rid of in the liquid lines, got rid of promptly fastening, the usefulness of 5 seal fluids of seal ring.Seal ring 8 is buffering usefulness, plays the protection plug in order to avoid the effect of transfiniting is inflated control cock 10 for giving the admission port that fills air, and it plays regulating action.

This controller is about 100 millimeters, and volume is compact.Housing adopts alloy aluminum, and aie escape valve, plug sleeve, stick harness, inflation control cock all adopt the 45# steel, and the switching mouth adopts brass, and plug is then made of hard high resiliency oil proof rubber.

The utility model effect:

In the automobile of various brake fluid systems, use and all can effectively proofread and correct brake side-slipping, prevent wheel lock up, and alleviate tire wear, simultaneously can shorten braking distance, greatly improve the braking effect that vehicle travels at ice and snow, rainwater and expressway surface, but straight line is controlled, kept to equal stabilising direction in any brake hard situation.
