Description

For the hydraulic brake system of two-wheel car

Technical field

The present invention relates to a kind of for the device of adjustable brake system, in particular for regulating the brake system of two-wheel car of for example bicycle.

Background technology

Simple bicycle is more and more welcome.Because the requirement that this kind of bicycle promoted day by day always further improves this kind of bicycle.Except purely there is increasing modification by manually driven machinery two-wheel car, it combines with electric driver at least in part in the meantime.Electrical Bicycle to this embodiment.The present invention but also can be applied in little motorization two-wheel car.

The average velociity that improves this two-wheel car by various improvement projects is possible.Thus but also always brake system is proposed to higher requirement.

Therefore known such brake system in the prior art, it is by plate disc brake, drum brake mechanism and rim brake work, and they are with polyspast or hydraulically handled.After realize manipulation by driving chain pedal lock in the situation that.

If handle the brake rod on handlebar in bicycle, start so braking procedure.If pulled, one or more brake shoes are pressed onto so to wheel rim or the wheel hub of wheel in most situation on brake rod.In the embodiment of the rim brake often using, apply in addition dragline type drg and hydraulic brake.

But these brake system for two-wheel car only have control and there is no a feature of adjusting.For example the force limiting device of stay cord or the indirect force restraint device that passes through the adjusting in the manipulation path on brake rod for the single system of braking force restriction.

For at just Antilock brake system not of braking procedure, develop simple machinery anti-locking apparatus.But could not realize so far this system.

Modern rim brake and plate disc brake have now become better and better and B.P. first faster.This expression, current brake system has realized more and more higher braking deceleration.

But the problem of B.P. of improving is, always more often cause falling and and then causing severe injury by handlebar chaufeur.

This has additionally been realized to more and more higher average velociity by the electric driver in two-wheel car or bicycle.Naturally increased thus the accident risk in so-called Electrical Bicycle.

In the two-wheel car with electric driver, additional advantage is, can use for control system electric energy now.

First and foremost stop the tumbling chaufeur by front truck according to device of the present invention.Stop equally the locking of wheel by this system as other function.By this system chaufeur in braking by initiatively and optimally support and improved B.P..

Summary of the invention

The present invention proposes a kind of for regulating the device of brake system of two-wheel car according to the first aspect of claim 1.This device comprises at least one sensor, and whether described sensor rises from road surface for detection of the trailing wheel of described two-wheel car.

In two-wheel car, for the embodiment of above-mentioned rim brake, in the time of the brake rod of handling on handlebar, close two brake control levers of drg.By the friction producing, bicycle is slowed down.If the deceleration on front-wheel is too large, trailing wheel faces by front truck the danger of tumbling from road surface rise and whole two-wheel car so.

In order to identify, whether two-wheel car rises also and then faces the danger of tumble (ü berschlag) from road surface, and this sensor can detect two-wheel car trailing wheel and whether rise and apply different information from road surface.Specifically, acceleration/accel, wheel revolutions, the vehicle wheel rotational speed that not only can apply wheel also can be applied the every kind of combination being made up of these observed readings.

Hydraulic brake represents a kind of drg, and its power transmission hydraulically realizes, and that is to say by the liquid in pipeline and realizes.Hydraulic brake is so that than traditional mechanical brake, significantly better feature is convincing.Therefore hydraulic brake can carry out significantly better dosage and have higher braking force.

Be connected with two brake control levers via hydraulic tubing at this brake rod, described brake control lever is arranged on the both sides of wheel rim of wheel.In the time of braking, it is upper that the opposed lining face of being made up of agglomerated material is forced into two wheel rim sides (Felgenflanken), thereby produce brake action by friction.Rim type drg is not only applicable to simple daily wheel and is applicable to competitive sport field.For rim type drg, above tire, only there is the system of an attachment point and having between the system of double-body bike of two attachment points distinct in wheel rim both sides.

Can additionally identify and stop the locking of front-wheel and trailing wheel by measuring wheel revolutions according to device of the present invention.Especially front-wheel always keeps manipulating thus.

In addition,, according to the inventive system comprises at least one unit, described unit is for hydraulically throwing off the drg of described two-wheel car.The unit that is used herein to hydraulic pressure disengagement can directly be engaged in hydraulic tubing, and this represents, has reduced the pressure of hydraulic tubing by the unit of the drg for hydraulically throwing off two-wheel car, and the braking force of brake control lever disengagement and drg reduces thus thus.In the time no longer needing no longer to work for the unit of disengage brake and this unit, the pressure in hydraulic tubing raises again so, and drg obtains again its original braking force thus.

The unit of throwing off for the hydraulic pressure of the drg of two-wheel car can be implemented as a pure hydraulic efficiency pressure system, for preventing wheel lockup or also for detection of the rise of trailing wheel and and then for avoiding chaufeur to tumble by handlebar.In addition also can consider electro-hydraulic system, it is connected hydraulic efficiency pressure system with electric driver.

In addition, also comprise controller according to device of the present invention, in the time that described sensor detects that the trailing wheel of described two-wheel car rises from road surface, described controller is given an order to the unit of the drg for hydraulically throwing off described two-wheel car, thereby throws off the drg of described two-wheel car.

If controller identifies possible tumble or trailing wheel rises from road surface, so for example the actr in front wheel brake loop is triggered.Brake control lever is opened and front-wheel can rotate more quickly, thereby avoids tumbling.

After trailing wheel is located at again on road surface subsequently, controller turn-offs throws off the unit of two-wheel car drg and brake system for hydraulic pressure and continues not regulate intervention and work.

Be applicable to every type in drum brake mechanism, plate disc brake and rim brake according to device of the present invention in principle.

The advantage of the device proposing is, this system have all adjustings advantage realized active adjustment and intervened in bicycle braking system.First stopping distance due to optimum brakig force distribution and support is shortened and stoped simultaneously chaufeur by front truck tumbling.

In addition according to device of the present invention by this ABS(antiblock device) function stops the locking of wheel.This has caused again and has prevented that wheel from sliding and avoiding thus falling and improving the travelling characteristic of two-wheel car.

In addition, by this system when braking initiatively and optimally support chaufeur and improve B.P..

Preferably, at least one sensor the sensor whether rising from road surface for detection of the trailing wheel of described two-wheel car is acceleration pick-up.Acceleration pick-up is measured the position of bicycle and this observed reading is transferred to controller.Can identify and tumble or trailing wheel rises from road surface by the vector of acceleration pick-up at this.Acceleration pick-up can be shifted and detected center-of-gravity position and consider in adjusting by the center of gravity of chaufeur.

In addition at least one sensor the sensor preferably, whether rising from road surface for detection of the trailing wheel of two-wheel car is tachometer generator.Generally should on two wheels each, tachometer generator be installed.Obtain respectively from the observed reading of the wheel revolutions of front-wheel and trailing wheel transmission at this controller.Tumble so and can identify by the limit revolution difference that the past takes turns to trailing wheel.

Because wheel revolutions sensor measurement wheel revolutions, so also can be by the whether locking of wheel revolutions sensor measurement wheel, that is to say and stop.Can in the time facing the static threat of wheel, trigger thus the actr of corresponding wheel.Therefore throw off corresponding brake control lever.This means, by also can prevent the wheel lockup of two-wheel car according to device of the present invention.

In addition at least one sensor the sensor preferably, whether rising from road surface for detection of the trailing wheel of described two-wheel car is tachogen.Tumble or trailing wheel rise also can identify by tachogen.Tachogen is measured the rotative speed of main body.

Combination by different sensors information (acceleration pick-up, wheel revolutions sensor and tachogen) can be identified and tumble better.

At least one unit of in addition preferably, throwing off for the hydraulic pressure of the drg of described two-wheel car is hydraulic actuating cylinder and the electric driver of double action.This is introduced in hydraulic tubing to hydraulic actuating cylinder.By brake activation bar mineralization pressure in the upper chamber of cylinder, thereby the plunger of hydraulic actuating cylinder moves down and activate drg and braking two-wheel car simultaneously.On the plunger of hydraulic actuating cylinder, be fixed with a tooth bar.

By one for example to be fixed with gear on it electric driver of the motor form of---described gear moves on tooth bar---can intervene equally in brake circuit so.

Use hereinafter longitudinal conduct of axle drive shaft for the system of axes of the hand of rotation of electric driver or motor, in view of axle from electric machine casing out.

If motor cw or to right rotation, tooth bar moves up so.Fluid pressure in drg discharges and drg disengagement thus.

If but motor conter clockwise or to right rotation, tooth bar moves down so.The brake action of the rising of the fluid pressure in drg and drg increases thus.People adjustably intervenes in system in this way.

At least one unit of in addition preferably, throwing off for the hydraulic pressure of the drg of described two-wheel car is gear type pump and electric driver.Gear type pump is encased in the hydraulic tubing between brake rod and the drg on handlebar at this.In the time of brake activation bar, braking liquid is pressed onto in gear type pump.The braking liquid in rotation of gear in this gear type pump based on flowing into.Braking subsequently liquid flow in drg.In drg, setting up thus brake-pressure and drg slows down two-wheel car.

If relieving brake rod, drg is thrown off so, because braking liquid can reflux again.This means, produce low pressure in the time decontroling brake rod, it pulls braking liquid to get back in the main brake cylinder in brake rod by hydraulic tubing and gear type pump.

If electric driver, as motor and gear type pump coupling, can regulate this system so.Embodiment to this is that one of them is connected two wheels of gear type pump with motor.If motor cw or to right rotation, is transported in the main brake cylinder on brake rod by braking liquid by drg so and drg is thrown off.

If motor left-hand revolution, is transported to braking liquid in drg by brake rod so, brake-pressure raises and drg braking thus.Brake system adjustably interferes with in brake circuit in this way.

In two above-mentioned embodiments, the cylinder of double action can be by gear type pump exchange on the contrary.

In addition preferably, there is another hydraulic circuit and complementary tank at least one unit of throwing off for the hydraulic pressure of described two-wheel car drg, if the sensor whether rising from road surface for detection of described two-wheel car trailing wheel one of them to measure described two-wheel car trailing wheel raised, be switched to so described another hydraulic circuit and complementary tank.

In the braking procedure of " normally ", do not intervene in drg with regulating, move main brake cylinder and pressure foundation by means of brake activation bar by mechanical connection.

Braking liquid in this main brake cylinder, by hydraulic tubing, flow in direct wheel braking cylinder on drg., with respect to wheel rim extruding brake shoe, activate thus braking now.

If decontrol again now brake rod, the piston of main brake cylinder is withdrawn into initial position by the spring in main brake cylinder.This moves can be additionally by another spring support in wheel braking cylinder.During piston in main brake cylinder moves to its initial position, produce low pressure in main brake cylinder, it turns back to again in main brake cylinder for the braking liquid of hydraulic tubing simultaneously.

If now by the ground braking of brake rod degree like this, wheel lockup or trailing wheel are risen from road surface, this means, bicycle faces the threat of tumbling forward, can reduce the brake-pressure in the drg of corresponding wheel and finish thus the locking of wheel.A valve is installed in the hydraulic tubing between main brake cylinder and wheel braking cylinder for this reason.It is 3/2 change-over valve with spring reset for the embodiment of such valve.

If the pressure confinement in wheel braking cylinder is too high, this pressure can discharge by the described valve of conversion so.Flow back in complementary tank by changing the braking liquid of described valve in another pipeline.

If present wheel tachometer generator identifies wheel and faces a danger again, this valve connects again and gets back to original hydraulic tubing so, and the filling of the pressure existing in main brake cylinder and hydraulic tubing based on wheel braking cylinder prevents that pressure drop from acting on again wheel braking cylinder.Intervene (also referred to as ABS(anti-lock) and intervene regulating) pressure of front existence can reach again by more manipulations path of for example brake rod.But this control process is not to continue longways without stopping.Because do not know that main brake cylinder when is empty and brake system can no longer be braked.

Therefore in addition preferably, the unit of throwing off for the hydraulic pressure of described drg also comprises horizontal limeit switch, if the fluid level of described main brake cylinder reaches a minimum value, so described horizontal limeit switch turn-offs the unit of throwing off for the hydraulic pressure of described drg.

This horizontal limeit switch is arranged in wheel braking cylinder or goes up and trigger in the time that fluid level reaches a minimum value.In the time of piston arrives horizontal limeit switch in main brake cylinder, can be such situation so.

In the time arriving this horizontal limeit switch, this limit switch interrupts actr power supply, namely voltage, and it is transformed into another hydraulic tubing by described valve from the first hydraulic tubing for controller.Therefore further regulate subsequently intervene no longer may and nonetheless chaufeur can be also can do not regulate intervene or ABS function may down bicycle be remained static.

If now decontrol again the brake rod on handlebar, cylinder is withdrawn into again its initial position by the spring in main brake cylinder.This moves additionally and supports by wheel braking cylinder, and this wheel braking cylinder has the feature that spring is replied.The wheel braking cylinder that this spring is replied is for guaranteeing the reply of brake shoe.

In the time that the piston in main brake cylinder is moved back into its initial position, wherein produce low pressure, this low pressure is opened for a boiler check valve simultaneously, and this boiler check valve is arranged in the hydraulic tubing between main brake cylinder and complementary tank.Braking thus liquid flows to main brake cylinder from complementary tank.

And if then the low pressure in main brake cylinder reaches and approaches zero, because this main brake cylinder is full of again braking liquid, the spring of boiler check valve based on integrated closed again.

For working well according to device of the present invention in this embodiment, the capacity in main brake cylinder should be large than the capacity in wheel braking cylinder.

If the piston arrives horizontal limeit switch of main brake cylinder, the power supply of this horizontal limeit switch opens and then interruption valve, this valve should be moved back into again its initial position thus.Therefore should apply the valve of self replying.

Guaranteed thus, main brake cylinder can not be empty and chaufeur always has the possibility of braking two-wheel car.

Spring in valve can be for, and under failure condition, in the system failure situation of for example electric apparatus, this valve connects to be got back to its initial position and guarantees thus, and normal braking function always can be used.This represents backup.

While not using electronic 2/2 change-over valve when using boiler check valve as valve, this system needs the energy still less so, and this system also becomes more cheap based on simpler valve.

The advantage of two power supplys is, the voltage monitoring of the power supply of actr is possible on the one hand.Microcontroller in controller detects this battery exhausting and informs chaufeur by means of vision and/or auditory message.

Therefore, there is microcontroller, life-span that for example power supply capacity of controller of the bicycle speed meter (Fahrradtacho) of expansion is designed for the long life and then is significantly longer than actr.

So chaufeur should by instruction (handle instruct and/or field range in instruction) make to note, according to device of the present invention only when bicycle speed meter and integrated ABS logic device ready can use while being arranged on bicycle." ABS ok " message in the time packing speed gauge into this embodiment.

The inactive of some ABS not relying on above can represent to two-wheel car chaufeur by display.One may be, people connect a LED in the time of ready ABS.If the battery of actr exhausts, so LED extinguish and ABS no longer ready.

Spring in wheel braking cylinder is used for, and brake shoe reaches terminal position and then drg disengagement to getting back to reliably.

Another advantage of this system is, does not need pump for this system.Braking liquid from wheel braking cylinder is delivered in main brake cylinder to feedback by spring and vacuum.

Because do not need pump for this system, so this system needs only considerably less electric energy.This system only needs for triggering in short-term valve and selectively for the electric energy of microcontroller.

All embodiments of mentioning are not only applicable to drum brake mechanism and are applicable to plate disc brake and rim brake yet.

Detailed description of the invention

Fig. 1 shows the schematic diagram of two-wheel car 1, and described two-wheel car is a bicycle in this case, the sensor whether it has controller 50 and rise from road surface 5 for detection of the trailing wheel 10 of bicycle 1.This is provided with to sensor unit 20 in the framework 12 of bicycle 1.Preferred sensor unit 20 is arranged near the center of gravity of bicycle, is arranged in this case under vehicle seat 25.

Exist different technical schemes to rise from road surface 5 by handlebar 18 trailing wheel 10 in other words of tumbling to determine bicycle.

A kind of technical scheme that identification bicycle is tumbled is to measure by the vector of acceleration pick-up 22.Therefore sensor unit 20 comprises acceleration pick-up 22, and described acceleration pick-up is measured the position of bicycle 1 about road surface 5.Sensor 22 acceleration measurements, method is that described sensor is determined the force of inertia that acts on test mass (Testmasse).For example can determine acceleration/accel, method is that detection effect rises or acceleration/accel decline in the acceleration/accel of test mass.In addition acceleration pick-up 22 can be detected and be considered by the gravity motion of chaufeur the center-of-gravity position of bicycle 1.In addition acceleration pick-up 22 is also measured the position of bicycle 1 about road surface 5.

In addition, sensor unit 20 additionally has tachogen 30.Tachogen 30 is measured the rotative speed of main body in the situation that being bicycle and can be identified thus tumbling of bicycle 1.This means, tachogen 30 is measured bicycle 1 forward by the possible rotation of handlebar 18, such as in the situation that tumbling.Tachogen 30 but also can be arranged on sensor unit 20 outside and/or be arranged on another position of bicycle 1.

In addition, tumbling also can be by

wheel revolutions sensor

40,40 measurement in other words of revolution speed measuring device.Be fixed on trailing wheel 10 and a wheel revolutions measurer 40 is fixed on front-wheel 16 to this wheel revolutions measurer 40.The rise of trailing wheel 10 in other words of tumbling of bicycle 1 can be identified by the limit revolution difference of front-wheel and trailing wheel.

The sensor information of acceleration pick-up 22, tachogen 30 and revolution speed measuring device 40 is detected and determines whether to face trailing wheel 10 by means of applicable software and rises the danger of tumbling in other words from road surface 5 in controller 50.Controller 50 determines whether intervene in brake system to its adjusting subsequently.

Certainly not only the information of acceleration pick-up 22, tachogen 30 but also wheel revolutions measurer 40 is individually applicable to detect the trailing wheel 10 that whether faces bicycle 1 and rises the danger of tumbling in other words from road surface 5.But whether the better and faster information of combination results of two or even all three sensor informations faces to detect the danger of tumbling.

Can stop in the following manner the rise of trailing wheel 10 in other words of tumbling that has threat, the brake shoe brake cheek of front-wheel 16 (Bremsback) is opened and therefore drg throws off.Front-wheel 16 can rotate again more quickly thus, thereby avoids bicycle 1 to tumble by handlebar 18.

Have multiple technologies scheme for regulating to intervene in brake system, they can be shown in accompanying drawing subsequently.Represent in the accompanying drawings identical constant part in other words of the present invention at this identical Reference numeral.

Therefore Fig. 2 shows the schematic diagram of the embodiment of the unit of the drg for hydraulically throwing off bicycle 1.

In the time that braking, hydraulic brake usually on the handle 115 of handlebar 18, pulls brake rod 110.Brake rod is connected with drg 130 via hydraulic tubing 120.Two brake control levers 132 and 134 of drg 130 are closed and drg 130 is braked front-wheel 16.

According to the present embodiment of device of the present invention, now the hydraulic actuating cylinder of a double action 140 is joined in the hydraulic tubing 120 between brake rod 110 and the drg 130 on the handlebar 18 of bicycle 1.By brake activation bar 110 build-up pressure in the upper chamber 142 of hydraulic actuating cylinder 140.Thus the piston 145 in hydraulic actuating cylinder 140 decline and in the second chamber 147 of hydraulic actuating cylinder build-up pressure again, described pressure is used for activating drg 130 and brake bicycle 1.

The piston 145 of hydraulic actuating cylinder 140 is connected with tooth bar 150 now.Motor 170 is adjustably engaged in brake system now thus, and this motor is connected with gear 160.

If controller 50 is identified and faced the danger of tumbling by acceleration pick-up 22, wheel revolutions sensor 40 and/or tachogen 30, controller 50 impels cw rotating machine 170, gear 160 to the right in other words so.And then gear 160 tooth bar that moves up.Piston 145 also moves up and then disengage brake 130 simultaneously.

When controller 50 sends this motor to motor 170 should conter clockwise during in other words to the order of anticlockwise, gear 160 fixed thereon moves down tooth bar 150, this tooth bar is connected with piston 145.At this downward extrusion piston, close drg 130 and improved again the braking effect of drg 130.

Fig. 3 shows the schematic diagram of the another kind of embodiment of the unit for hydraulically throwing off cycle brake.And be arranged between the brake rod 110 and drg 130 on handlebar 18 at this hydraulic tubing 220.Hydraulic tubing 220 moves by the gear type pump 230 with

gear

233 and 236 in this case.

If now push brake rod 110 with respect to the handle 115 of handlebar 18, via hydraulic tubing 220, braking liquid be pressed onto in pump 230

so.Gear

233 and 236 is the braking liquid in rotation based on flowing into and then.In hydraulic tubing 225 subsequently, the same rising of pressure and drg 130 are activated thus.And then bicycle is braked.

If decontrol now brake rod 110, braking liquid flow back in brake rod and drg is thrown off again.

Adjustably intervene in brake circuit by motor 270, one of them is connected this motor and two

gears

233 or 236.

If now controller 50(that is to say control convenience) trailing wheel 10 in other words of tumbling that identifies threat rises from road surface, sends signal so to motor 270.

If the order of the controlled device 50 of motor 270, gear 236 cws are in other words to right rotation so.And then braking liquid is transported in the main brake cylinder brake rod 110 and drg disengagement from drg.

If controller 50 sends signal to motor 270, this motor no longer faces the danger of tumbling, so motor 270 conter clockwises swing pinion 236 left in other words.Thus braking liquid is transported in drg 130 by brake rod 110.Therefore the rising of the brake-pressure in drg 130 and drg 130 can be fallen again its total brake-pressure.

Fig. 4 shows according to one embodiment of the present invention for hydraulically throwing off the schematic diagram of unit of drg 470 of two-wheel car 1.

When according to the brake system of Fig. 4 during with respect to handle 115 extrusion lever 110 of handlebar 18, build-up pressure in pipeline 420 so.Pipeline 420 can be mechanical connection also or hydraulic tubing.If pull brake rod 110, so piston 432 is expressed in main brake cylinder 430.Main brake cylinder 430 comprises braking liquid, and this braking liquid is extruded in pipeline 425 and subsequently and is forced in wheel braking cylinder 450 by valve 440.

Now with respect to the wheel rim extruding

brake shoe

452 and 454 on tire 458.Activate thus drg and make two-wheel car or described bicycle 1 slows down.If decontrol again now brake rod 110, piston 432 is withdrawn into again initial position by the spring 434 in main brake cylinder.

This movement is additionally supported by spring 460 or wheel braking cylinder 450 in wheel braking cylinder 450.This spring 460 is for pushing back again its initial position by piston 462.

In the time that the piston 432 of main brake cylinder 430 moves to its initial position, in main brake cylinder 430, produce low pressure, it flow back into again main brake cylinder 430 for braking liquid from pipeline 425.

Whether the trailing wheel 10 of bicycle 1 rises in addition and can measure by acceleration pick-up 22 from road surface 5.This acceleration pick-up 22 can be measured around the acceleration/accel of lateral axis, longitudinal axis and vertical axis.

The technical scheme whether another kind of trailing wheel 10 of measuring bicycle 1 rises from road surface 5 can realize by tachogen 30.This tachogen 30 is measured luffing speed (Nickrate), inclination speed (Rollrate) and yaw velocity (Gierrate).

In addition bicycle 1 can not only have tachometer generator 40 on front-wheel 16 but also on trailing wheel 10.Whether the trailing wheel that relatively can judge bicycle 1 10 by corresponding revolution rises from road surface 5.

Produce individually or in combination about the trailing wheel 10 of bicycle 1 and whether rise from road surface 5 and and then face the dangerous situation of tumbling from the observed reading of acceleration pick-up 22, tachogen 30 and wheel revolutions sensor 40.

Three observed readings of described three

sensors

22,30 and 40 supply power to controller 50 by system bus 52.Whether controller 50 for example rises from road surface 5 and and then must intervene to brake system by means of the trailing wheel 10 of microcontroller and applicable software detection bicycle 1.

If now controller 50 identifies degree like this and pushes brake rod 110, make front-wheel 16 lockings and bicycle 1 face the danger of tumbling forward, can reduce so the brake-pressure in drg 470 and avoid thus the locking of front-wheel.Front-wheel 16 rotates again and has avoided tumbling thus.

If the pressure in wheel braking cylinder 450 is too high, this pressure can discharge by the switching of valve 440 so.If valve 440 is transformed into position b by position a, brakes so liquid and flow in pipeline 427 and from flow to complementary tank 480 there.Liquid flows out from wheel braking cylinder 450 thus, and drg 470 is thrown off and avoided tumbling.

If controller 50 identifies, trailing wheel 10 drops to again on road surface 5, and valve 440 is switched to position a and main brake cylinder 430 and the pressure that exists

hydraulic tubing

420 and 425 is had an effect from position b again so.

Be eager the now filling of wheel braking cylinder 450 of this pressure reduces pressure drop.The pressure existing before at this anti-lock (ABS) can be now a little more handled path implement by brake rod 110 again.But this control process can no longer continue without stopping ground.No matter when when main brake cylinder 430 sky, that is to say that no longer including liquid is located in main brake cylinder 430 and brake system can no longer be braked.For fear of this point, there is horizontal limeit switch 490.

This horizontal limeit switch 490 is located at the inside of main brake cylinder 430 or outside main brake cylinder 430 and measure and brake the fluid level of liquid or the position of main brake cylinder 430 inner carriers 432 in main brake cylinder 430.If piston 432 is pressed in main brake cylinder very deeply, arrive horizontal limeit switch 490 by piston 432 so.And then horizontal limeit switch 490 interrupts power supply 492, thereby further adjusting intervention is no longer possible and nonetheless chaufeur can make bicycle 1 remain static under the condition that there is no ABS function.

If decontrol again now lever 110, the spring 434 in main brake cylinder 430 is withdrawn into its initial position by piston 432 again.This moves additionally and supports by the spring 460 in wheel braking cylinder 450.This be again spring reply wheel braking cylinder 450 also for guaranteeing the reply of

brake shoe

452 and 454.

When the piston 432 in main brake cylinder 430 is moved back into its initial position, in main brake cylinder 430, produce low pressure, it can open for boiler check valve 485 simultaneously and then the braking liquid of hydraulic tubing 487 can be flow back in main brake cylinder 430 by complementary tank 480.

If the low pressure in main brake cylinder 430 approaches zero now, this represents that main brake cylinder 430 is full of again braking liquid, and the spring 488 of boiler check valve 485 based on integrated closed again.

As seen in Figure 4, the volume in main brake cylinder 430 is enough large than wheel braking cylinder 450, therefore has the high availability of ABS system.

If piston 432 arrives the horizontal limeit switch 490 in main brake cylinder 430, the power supply 492 of this horizontal limeit switch opens and then interruption valve 440 so, this valve can move back to namely position a of its initial position thus.Should use this from replying valve.Guarantee thus, main brake cylinder 430 is not empty and chaufeur thus always can brake bicycle 1.

If at the electric apparatus et out of order according in brake system of the present invention, in valve 440, should there is a spring, this spring that is to say position a for valve 440 is returned to its initial position, thus bicycle 1 can be braked.

If do not use electric 2/2 change-over valve as boiler check valve 485, this system need to the energy and this system still less be also favourable based on simple valve so.

Additionally controller 50 has the power supply 54 of self.This advantage having is, the voltage monitoring of the power supply of valve 440 is possible.If controller 50 is determined running down of battery, this can be by means of vision and/or auditory message driver so.This expression controller 50 informs that chaufeur ABS function is no longer ready.Controller 50 can be connected to this in bicycle speed meter of an expansion.

The capacity of the power supply 54 of controller 50 can be designed for the longer life-span (>1) and then significantly be longer than the power supply 492 of valve 440 for this reason.

So by instruction (handle instruct and/or field range in instruction) should cause the attention of chaufeur, thereby according to device of the present invention only when bicycle speed meter and integrated ABS logic device ready can use while being arranged on bicycle.This can for example realize by " ABS ok " message in the time packing speed gauge into.

The inactive of some ABS not relying on above can represent to two-wheel car chaufeur by display.One may be, people connect a LED in the time of ready ABS.If the battery 492 of actr 440 exhausts, so LED extinguish and ABS no longer ready.

Spring 460 in wheel braking cylinder 450 reaches terminal position and then drg is thrown off to getting back to reliably for, brake shoe.

Do not need pump for system shown in Figure 4.Braking liquid from wheel braking cylinder 450 is delivered in main brake cylinder 430 to feedback by spring and vacuum.Because do not need pump for this system, so this system needs only a small amount of electric energy.This system only needs for triggering in short-term valve 440 and selectively for having the electric energy of controller 50 of microcontroller.

All brake system of mentioning are not only applicable to drum brake mechanism and are applicable to plate disc brake and rim brake yet.

The present invention is not limited to the embodiment proposing, but also can modify by object according to the present invention.
