Summary of the invention
Therefore, the purpose of this invention is to provide a kind of anti-lock that is used for bicycle and Electrical Bicycle and anti-skidding mechanical brake system, comprise simple, reliable, durable system, it is applicable to using together with any bicycle type, size and purposes (for example, mountain region, motion or road cycling).
Anti-lock of the present invention and anti-skidding mechanism principle behind is, the moment of torsion that is produced by the vehicle load wheel is as making same power source of taking turns release during emergency brake, thereby allows wheel near the friction point place rotation of locking point.
Therefore, provide a kind of anti-lock braking system that is used to turn a wheel and slows down or stop, having comprised that the mechanical braking force that is used for applying reduces and remain on the device of a benchmark, described benchmark is lower than the torsion forward of wheel, thereby avoids dangerous wheel lockup.Keep this benchmark, reach enough low speed up to wheel and make locking cause bicycle or other vehicles to stop in the mode of overall safety, and till the moment that can not fly out or skid.
Preferably, described device comprises at least one movable push rod and at least one force application component that is connected thereto, thereby helps to apply the friction braking force to wheel.When force application component during excessive brake during with the instantaneous locking of wheel, force application component is suitable for wheel small distance movement forward.When force application component travelled forward, this caused the push rod automatism on force application component, thereby caused force application component to move in the anti-lock mode, thereby removed the locking on the wheel.
Two preferred implementations will be described below.At first, be suitable for using with the V-type drg, force application component is equivalent to a pair of brake control lever and the brake shoe that links to each other.Like this, at brake control lever because wheel lockup and under the situation that wheel pulls forward, pair of push rods acts on the brake control lever, thereby cause their outside motions, away from wheel rim.In the second main preferred embodiment, be used for using with plate disc brake, force application component is equivalent to brake housing and gear assembly.Like this, push rod is connected on the gear assembly, make when brake housing because locking is former thereby when pulling forward with described dish, push rod moves so that the brake action on the gear assembly is reverse, thus the brake housing locking on the releasing wheel.
Therefore, provide a kind of anti-lock braking system in first preferred embodiment of the present invention, comprised a pair of brake control lever, each brake control lever has the slipper that is connected to its lower end, is used for wheel brake activation power.Brake control lever is suitable for inside motion, and it can pass to slipper with the brake action that applies in the mode that is similar to traditional brake system.Antiblock device also comprises a pair of movable push rod, and it at one end is connected to the top of brake control lever, is connected on the main spring through tracker (tracker) at the other end.When brake control lever inwardly moved during initial brake, push rod is inwardly motion in the corresponding way, and spring is owing to brake action compresses.Brake control lever also is suitable for travelling forward, make when slipper and brake control lever when locking is to wheel under the situation of generation emergency brake, brake control lever pulls forward with wheel.The towing forward of this brake control lever allows push rod outwards to retreat, thereby causes the corresponding outwards motion of brake control lever.When brake control lever outwards moved, the locking of slipper on wheel removed.Will be appreciated that the slipper on the wheel only allows the moment locking, so that trigger the anti-lock action.
Therefore, second preferred implementation according to the present invention also provides a kind of anti-lock braking system that uses with plate disc brake.This system comprises the brake disc that is connected on the wheel center axle, is used for making wheel decelerates when friction force is applied on the dish, and is such as known in the art.This system also comprises brake housing, and this brake housing comprises gear assembly, and the brake-force transmission that is used for applying is given brake disc.When brake housing was taking place that locking is to described dish under the situation of emergency brake, this brake housing was suitable for travelling forward with this dish.This system also comprises and is connected to gear assembly and is connected at least one movable push rod on the main spring.Push rod is suitable for rotating forward, makes that push rod promotes with corresponding manner, thereby causes push rod to act on the gear assembly in the anti-lock mode when the brake housing locking is last to dish, and like this, the locking of the brake housing on the described dish is removed.Preferably, push rod is connected on the gear assembly through swivel coupling, makes push rod act at least one gear of gear assembly, like this, gear rotates along the direction opposite with initial brake action, and therefore the effective skin friction on the dish reduces to the benchmark that is lower than wheel torque.

The specific embodiment
Provide following explanation with all chapters and sections of the present invention, thereby made all technical personnels in this area can utilize described invention, and proposed by the best mode of realizing that the present inventor considered.But, because clearly being defined as, General Principle of the present invention provides a kind of anti-lock that is used for bicycle and/or all wd vehicles and anti-skidding mechanical brake system, therefore various improvement are apparent for a person skilled in the art.
Term " bicycle " typically refers to all bicycles (especially motion and mountain bike), string seat tandem bicycle, carriage, hand barrow, motor bike in the present invention; The mini-motorcycle and the similar vehicle; Also referring to stop or slowing down accidentally by controlled manner with at least one rotation loadwheel is any vehicle or the automobile of feature.For simplicity, hereinafter will be described according to bicycle.
Term " spring member " is meant any spring in the present invention, coil spring or other spring-like members; Spring assembly (for example) around the clockwise direction disc spring of narrower anticlockwise direction disc spring, a plurality of parallel springs etc., hydraulic brake mechanism, the piston in the compressed liquid system, or the like.The invention discloses anti-lock and anti-skidding mechanical brake system.In the preferred embodiment that accompanying drawing shows, the brake system of bicycle is the V-type drg, as known in the art.In another preferred embodiment that accompanying drawing shows, brake and be disc type, be similarly known in the art.One of ordinary skill in the art appreciates that anti-lock of the present invention mechanism can also easily be applied in the braking of other types.
Will be appreciated that the present invention satisfies the needs that use with known bicycle brake system, described brake system has prevented to take place tyre skidding and locking when emergency brake.In the context of the present invention, " emergency brake " be meant that cyclist's application force that overuses activates braking mechanism, causes the situation of slipper locking wheel.Will be appreciated that mechanism of the present invention provides mechanical system efficiently, be used to make bicycle to slow down as quickly as possible, prevent from simultaneously to skid or locking.
With reference now to Fig. 1,, this figure is the end perspective view of anti-lock braking system according to an embodiment of the invention.This braking is characterised in that to have before driving fork (1), front-wheel (2a) and wheel rim (2).Bicycle slows down by the device of anti-lock brake assembly in a controlled manner, described device comprises two slight curving brake control levers (6) (6a), each brake control lever has the slipper (7) that is connected thereto (7a), slipper (7) (7a) is suitable for clamping wheel rim (2) during braking, thereby by friction force wheel (2a) is slowed down.In brake system known in the art, when the user activates bicycle brake, internal-direction-force be applied to brake control lever (6) (6a) on, thereby slipper (7) (7a) is pressed against on the wheel rim (2).
Will be appreciated that although the preferred embodiments of the present invention are described according to the front-wheel of bicycle, described mechanism can also easily be applied to trailing wheel, and two wheels of bicycle.
Still with reference to figure 1, anti-lock brake assembly of the present invention also comprises the main spring (4) that is contained in the spring housing (3a), and described spring housing is positioned at and drives fork (1) below and bicycle quick (2a) top.Anti-lock tracker (13) is used for spring (4) is mechanically connected to first push rod (5) and second push rod (5a), makes (5a) degree of compression of spring (4) during the brake of inside and outside motion effects of push rod (5).This process will be explained in more detail hereinafter.
Each brake control lever (6) (6a) is installed on the axis of revolution (8a), described axis of revolution can make brake control lever (6) (6a) inwardly move to realize braking with respect to wheel (2a), and when the braking force that applies reduces, outwards moving, thereby the effective braking force on the minimizing wheel (2a).Relative axle (6b) also is set, during applying excessive braking force, allows brake control lever (6) (6a) (7a) to travel forward with wheel (2a) and torsion thereof under the situation of locking wheel rim (2) at slipper (7).Each brake control lever (6) top (6a) is connected to push rod (5) end (5a), thereby activates anti-lock mechanism when needed.
With reference now to Fig. 2,, it has schematically shown when not using anti-lock braking system and bicycle quick freely to rotate, the top forward perspective view of anti-lock braking system shown in Figure 1.Described mechanism was shown as before any brake action and occurs and be in " relaxing " state.Be positioned at brake line cover (6c) in-to-in brake line (6d) and be configured to the brake action from the hand braking (not shown) of user is passed to each brake control lever (6) (6a), and when brake activation power, make (6a) inwardly motion (this will show) of brake control lever (6) in Fig. 3.In the embodiment shown, have single brake line (6d), it (6a) links to each other with two brake control levers (6).But, might there be independent brake line or the brake line parts more than, be used for brake action is passed to brake control lever, as be known in the art such.For purpose clearly, only shown a brake line.
Should be noted that under " relaxing " state push rod (5) (5a) is assumed to be to open and extends configuration, as shown in Figure 2, and spring (4) is in non-compressed state substantially.
Mechanism design of the present invention becomes can be when the user spurs brake line (using hand braking) and activated when about 4 kilometers/hour speed is advanced to be higher than when bicycle.Accompanying drawing has subsequently shown of the present inventionly how to operate in this case from activating anti-lock mechanism, thereby in the mode of safety bicycle is slowed down.
With reference now to Fig. 3,, its schematically shown when the user in order to realize brake pulling brake line when beginning brake operating, the top forward perspective view of anti-lock braking system shown in Figure 1.When braking activated with hand, a series of mechanical actions began.At first, the brake line (6d) in the pulling brake line cover (6c) causes brake control lever (6) (6a) owing to go up the former of rotation thereby inwardly rotation toward each other at axis of revolution base (8a).This motion is represented by the arrow A among Fig. 3.Brake control lever (6) inward turning (6a) produces along acting on the internal-direction-force of slipper (7) on (7a) perpendicular to wheel (2a) direction.The internal-direction-force of slipper (7) on (7a) cause slipper (7) (7a) inwardly motion (along the direction of " B " arrow) and apply friction force thereon with contact wheel rim (2), thereby begin process that wheel movement is slowed down.
Still with reference to figure 3, when brake control lever (6) (6a) inwardly moved, brake control lever (6) (6a) promoted push rod (5) (5a), caused push rod (5) (5a) inwardly to rotate with respect to the axis that is limited by anti-lock tracker (3).This motion is represented by the arrow C among Fig. 3.Spring (4) is according to the degree and the wheel torque compression of friction braking force.
Above-mentioned sequence of operation is carried out continuously, will produce deceleration as long as brake activation power and wheel (2a) still rotate.But if the cyclist applies over effect power to brake line (6c), brake control lever (6) (6a) will be gone up the generation friction force at wheel (2a) against slipper (7) leverage (7a), and it is greater than the whole application forces that influence loadwheel (2a).Therefore friction force will overcome the torque that is produced by wheel (2a), and cause wheel (2a) locking in its controlled deceleration process.The wheel lockup that carries out in the mode of just having described will trigger antiblock device immediately, thereby make the wheel release and allow bicycle to slow down with secured fashion.This releasing process will be described in ensuing accompanying drawing.
Referring now to Fig. 4, it has schematically shown when anti-lock mechanism activates owing to spring (4) compresses fully, the top forward perspective view of anti-lock braking system shown in Figure 1.When wheel (2a) and slipper (7) (7a) since bigger interior to friction energy and temporary transient " fusion " together when moving as one unit, releasing process begins.Gripping power on user's brake off is being out-of-action aspect the take-off the brake piece from wheel, thereby avoids bicycle to skid or fly out.Therefore, need other application forces so that the locking on the termination bicycle quick.
Anti-lock braking system of the present invention is by the torque self actuating of loadwheel, thereby slipper is unclamped from wheel: when slipper (7) (7a) locking when wheel rim (2) is gone up, slipper (7) (7a) and corresponding brake control lever (6) (6a) take place temporarily to pull forward along with the motion of wheel (2a).This towing is allowed owing to having opposed axle (6b), overcome the pressure of spring (4) and brake control lever (6) (6a) is pulled forward by wheel torque, make described opposed axle allow brake control lever (6) (6a) along with locking wheel is swung one section extremely short distance together forward.This towing campaign is represented by the arrow D among Fig. 4.Slipper (7) (7a) temporary transient locking is gone up and brake control lever (6) (6a) pulls forward and causes brake control lever (6) (6a) to be removed (5a) interior to thrust (describe in Fig. 3 interior be the result of initial brake action to thrust) of push rod (5) to wheel (2a).Push rod (5) (5a) is forced outwardly rollback thus, shown in the arrow E among Fig. 4.When push rod (5) (5a) was outwards opened, they caused brake control lever (6) (6a) outwards to be opened in the corresponding way, thereby caused slipper (7) (7a) from outwards motion of wheel rim (2), and therefore removed the locking on the wheel (2a).This motion is represented by the arrow F among Fig. 4.Will be appreciated that push rod (5) (5a) opens in the mode that is similar to the compass leg, this opens to provide and is used for take-off the brake piece (7) leverage (7a) from the wheel, and allows wheel to rotate under the situation that does not have bicycle to fly out or skid.
Will be appreciated that, when the cyclist still applies excessive braking force, above-mentioned a succession of action takes place.Because from activating anti-lock mechanism, wheel slows down continuously, and push rod provides the leverage that reduces friction force on the wheel, makes that wheel can locking between deceleration period.Be used to make the actual friction force of wheel decelerates to remain the time that the benchmark that is lower than institute's brake activation power reaches one section necessity, in order to avoid the slipper locking is to wheel.In case friction force fully reduces, and situation shown in Figure 5 will take place.
It should also be appreciated that the system of the present invention that uses, can not brake, as some anti-locking system for car in the anxious mode of stopping.On the contrary, system of the present invention has guaranteed the pulsation-free brake process.This be because it is found that push rod open " equilibrium point " or scope, make when applying excessive braking force the actual braking force that applies, promptly, slipper friction force on the wheel just keeps below the forward torque of wheel, thereby prevents locking, allows wheel decelerates simultaneously.
With reference now to Fig. 5,, it has schematically shown when anti-lock brake action stops, the locking action has just begun so that when realizing final stopping the top forward perspective view of anti-lock braking system again.Owing to make the torque of wheel decelerates become minimum, brake control lever (6) (6a) forward towing can be ignored.Therefore, push rod (5) (5a) begins closure once more under the braking force effect that applies, and (6a) inwardly promotion once more of brake control lever (6), as shown in Figure 3, thereby causes slipper (7) (7a) wheel to be applied whole braking forces.Shall also be noted that brake control lever (6) introversion (and export-oriented) (6a) moves through axis of revolution base (8a) and becomes convenient.Drop to the low value of the speed of travel when speed, for example 4 kilometers/hour the time, be applied on the brake line (6b) braking force with the withdrawal spring (4) pressure combine cause brake control lever (6) (6a) and slipper (7) (7a) wheel is applied lower pressure, it is much larger than the braking torque force of wheel.Therefore, wheel is with locking, so that bicycle is stopped fully.
With reference now to Fig. 6,, it has schematically shown when anti-lock braking system turns back to non-actuated condition, the top forward perspective view of anti-lock braking system of the present invention.In this case, do not have application force to be applied on the wheel, therefore, wheel freely rotates.
With reference now to Fig. 7,, it has schematically shown deceleration wheel and the application force that is applied to it.Wheel center is for a C, at a G place kiss the earth.Distance between C and the G equals radius of wheel, R.In a B place brake activation power, with center C partition distance R roughly.For simplicity, suppose that the distance between B and the G just in time is R.
Wheel is with cireular frequency W clickwise, and V moves along axis X with speed.Gravity is in reverse to axis Y effect along the direction perpendicular to X-axis.
Wheel heart C place therein is connected on the bicycle.The center of gravity of bicycle is along X-direction and C distance D.The weight of bicycle is H, comprises cyclist, capacity weight etc.
For force calculation F, take place brake action and therein wheel because a certain critical moment that brake action has just stopped operating, W=0, but bicycle still moves, V＞0 makes ground with application force T towing bicycle, and described application force T is used to stop cartwheel.
When application force T far surpassed a torque, bicycle may overturning.Calculate at a C place, T applies the torque that T multiply by R, or TR.The torque HD balance that this torque is applied by weight H.Bicycle can overturning condition be TR＜HD, and limiting case is TR=HD.
Observe wheel, the meshwork of bicycle remainder, when it stopped operating, the torque balance at C point place required FR=TR or F=T.
Therefore: HD=TR=FR, or
F＝HD/R
In a word, fly out under the dangerous situation in that bicycle does not take place, the maximum force that braking must apply and the weight of bicycle (comprising the cyclist, capacity weight etc.) are directly proportional, and are directly proportional with distance from the wheel to the mass center, are inversely proportional to radius of wheel.
Work as wheel, W＞0, and when brake supposes that wheel is in light weight and are not had moment of inertia, if tractive force T temporarily disappears, as one sliding take place on the ground, braking force F locking wheel immediately so, and how regardless of its size.Therefore, the critical force that prevents wheel lockup depends on road conditions.
Be described now with reference to Fig. 8,9 and 10 pairs of second embodiment of the present invention.The preferred embodiment relates to anti-lock and the anti-skidding mechanism that uses with traditional plate disc brake.Although its accurate structure difference, this embodiment carries out work in the mode identical with above-mentioned V braking type embodiment basically.That is, utilize the forward torque of wheel, so that prevent to trigger automatically under the situation of unsafe wheel lockup the anti-lock action at needs.Wheel torque provides leverage, is used to make the clamping of the slipper on the wheel reverse, thereby makes the wheel release under the emergency brake situation.
Combination is with reference to figure 8,9 and 10 now, and it has shown the optional scheme drawing of the anti-lock mechanism that uses with plate disc brake.This mechanism comprises dish (3), and wherein heart is connected on the main shaft (2c) of wheel.Slipper housing (7) is mechanically connected to dish (3) and upward and by hinge (7a) is connected on the main shaft (2c), therefore allows to rotate limited rotation distance around axletree (2c) under the emergency brake situation, and is as described further below such.
During brake action, the user spurs the brake line (6a) in the brake line cover (6).Pulling brake line (6a) causes gear (7b) to rotate (referring to Fig. 9), and it causes gear (7c) is rotated (referring to Figure 10) then.Gear (7b) (7c) is combined to form gear assembly, it should be noted that, other embodiment can comprise the gear of varying number.The disc brake pads that gear movement causes being positioned at housing (7) presses dish (3), and therefore makes the wheel decelerates that is connected thereto.Under the situation of excessively brake, when the friction pressure of going up slipper when dish (3) became greater than the forward torque of wheel (2c), housing (7) locking made dish (3), housing (7) and wheel combine as one unit to dish (3).When this happens, slipper housing (7) is pulled forward along the direction of curve arrow among Fig. 8 with wheel through the rotation on hinge (7a) by wheel torque.
Shown in 9, slipper housing (7) is connected on the push rod (5), and described push rod is mechanically connected on the loading spring (4a) that is contained in the spring housing (4), and described spring housing is connected on bicycle fork (1) or the vehicle frame.In addition, push rod (5) is connected on the gear (7b) by swivel coupling (5a).When housing (7) with dish (3) when the wheel movement direction travels forward, push rod (5) moves in the corresponding way.Yet because the existence of swivel coupling (5a), the motion of push rod (5) will cause push rod (5a) driven wheel (7b), cause gear (7b) to rotate (being also referred to as " anti-lock " mode) in opposite direction with respect to initial brake action.Make gear (7a) (7c) direction along direction in initial brake action rotation have and make slipper housing (7) a little away from the effect of dish (3), thereby the locking of the brake housing (7) on the dish (3) is removed, and prevent the bicycle locking of danger and skid.
Although invention has been described with respect to particular specific embodiment, but be to be understood that, this description is not limited to, and this is because further improvement is apparent for a person skilled in the art, and the present invention is used to contain this type of improvement that falls into the scope of the invention.
