Comparing with prior art, the invented disk type brake possesses the advantages of large braking force, high reliability, simple structure and low cost. The brake can widely be applied to automobiles and motorcycles and, especially it can stop saloon cars according to rule request without need of vacuum assistance system. The brake can be utilized at parking time or as an emergency brake. That is to say the hand brake can stop a saloon car in running, which is impossible for other existed brakes. The brake makes safety of saloon cars rise 1.5 times. Thus, it is most advanced brake in the world.
Description
The present invention relates to technical fields such as automobile, brake for motorcycle and clutch.
Break commonly used now (drum-type, big small piston reinforcement hydraulic disk) has braking force little (the usefulness factor is low), the required precision height, need power assist when requiring braking force big, reliability is low, cost is high, shortcoming such as emergency braking system can not be set, and drum brake also has two big fatal shortcomings of heat fade and water fade, and the present invention will solve the above shortcoming of above-mentioned two kinds of service brake.And the little and big shortcoming of steering force of solution clutch transmits moment.And a cover solution that provides.
The present invention is the patent of invention that I have applied for, denomination of invention: mechanical disc friction brake and plate clutch number of patent application: 98808763.4 applyings date: on September 11st, 1998 and the patent of invention of having authorized, the patent No.: ZL96101648.5 denomination of invention: lever clutch and lever brake patented technology embodiment's significant improvement.It is except the advantage that keeps former patented technology, it is under the situation that cost and difficulty of processing do not increase, its braking force and carry-over moment have been increased substantially, the same and in control run all without power assist, and under the braking force situation identical with carry-over moment, reduce steering force greatly, and significantly improved its reliability.This break and clutch are stepped on a new stage again.
Its structure and working principle are as follows, and as shown in Figure 1, it mainly forms (as shown in Figure 3) by parts such as brake disc, body, piston, slide block, lever block, thread plate, elasticity banking stop, torsion spring, steel disc, return cover, return springs.(A of arc portion shown in the accompanying drawing is mainly convex-concave garden arc to the A of arc portion on the lever block, but other can allow curved surface that lever block rotates can) locate with piston on concave-arc part (the arc portion shown in the accompanying drawing is mainly recessed garden arc, but other can allow curved surface that lever block rotates can) rotate and be abutted against, (the arc portion shown in the accompanying drawing is mainly recessed garden arc to concave arc groove B on the lever block, but other can allow curved surface that rolling element rotates can) in rolling element is housed (rolling element is generally roller, needle roller, roller bearings etc.), the afterbody C of lever block has a curved surface (can certainly be one or several inclined-plane) to be abutted against through rolling element 1 and slide block.Slide block is placed in the groove of piston, and its bottom and piston groove slide and be abutted against, and between its bottom and the piston groove rolling element can also be set, form rolling friction, reducing surface friction drag, the side is return and reduce steering force more, and the rolling element 1 that the afterbody with lever block is abutted against is equipped with on the top of slide block.Be abutted against rolling element of adorning on the lever block during braking and lever block and thread plate bottom plane, thread plate and body scyewed joint (more loosening), and piston is contained in the body and can slides up and down.
With the big reinforcement high reliable mechanical disk type brake of motorcycle is example (shown in the accompanying drawing 1), its working principle is as follows, when braking at the end, as the size minimum of eccentric e on accompanying drawing 5 lever blocks (center of protruding garden arc A and recessed garden arc B) on the y axle, the piston bottom surface is to height dimension P (size on the y axle) minimum of rolling element (this is a roller), produce the gap between the recessed garden arc on roller and thread plate bottom surface or the lever block, also producing the gap under the effect of brake disc and seal ring between brake shoe and the brake disc, break is in the brake off state.When needs are braked, the operator spurs wire rope and moves right, through joint sleeve, rivet, the transmission of steel disc, slide block moves right, and the afterbody C by rolling element 1 (this be a needle roller) promotion lever block, it is rotated to inhour, under the effect of the eccentric e of lever block, roller relies on thread plate (thread plate can not rotate) bottom under roller action, because the size of the eccentric e on the lever block on the y axle increases (size P also increases), piston is pressed towards brake shoe under the effect of the protruding garden of lever block arc, brake shoe is pressed to brake disc, and another road is that roller upwards promotes thread plate, thread plate promotes body and moves up, body is pushed down another piece brake shoe again and is pressed to brake disc, thereby brakes, as shown in Figure 6.When the needs brake off, operator's release handle, effect bottom slide block at return spring is moved to the left, slide block promotes lever block (boss is arranged above it) and rotates to clockwise direction, the size decreases (size P also diminish) of eccentric e on the lever block on the y axle, brake shoe promotes piston and moves up under the effect of brake disc and seal ring, produces the gap, the break brake off between two brake shoes and the brake disc.Automatic compensator after the brake shoe wearing and tearing is the same with the patent of invention (98808763.4) that I have applied for principle, only be to use the elasticity banking stop, it no longer pushes down banking stop with screw, and it is just spacing by the elastic force double thread plate of elasticity banking stop, thereby make when changing brake shoe more convenient, here just no longer detail introduced.The effect that slide is set is the manipulation aperture that reduces handle, and feel is improved, and another purpose is to allow the better return of handgrip, pushes down brake switch, and it is closed.A typing card of card (as shown in Figure 2) is in order to reduce to brake on steel cable, and vibration damper is compressed the anti-phenomenon that contracts of handgrip that the back produces.
One of its significant improvement is that the working surface between slide block and rolling element 1 (being preferably roller or needle roller) is designed to, and can allow rolling element 1 can change a curved surface or several curved surface (can certainly be one or several inclined-plane) of its size on Y-axis.Be more handy two planes easy to process (as shown in Figure 7).A plane D (during braking) when work mainly blocks rolling element 1 along horizontal plane motion, and another inclined-plane E is 1 vertical motion of major limitation rolling element when work.The relatively good design of D curved surface, its angle bigger can block rolling element 1 when work not and produce between the slide block and move horizontally (except the rotation of rolling element self) and get final product, D curved surface shown in the accompanying drawing 7 is a plane (inclined-plane vertical with the slide block bottom surface, curved surface also can), the E curved surface is in the highest point that it can reach slide block except guaranteeing rolling element 1 when working, it also should guarantee rolling element 1 when work not to the motion of the bottom of slide block, it should guarantee that also brake off rolling element 1 can be to the motion of the bottom of slide block simultaneously, so just return can be reliably made things convenient for, promptly when return, self-locking must not be produced between them.Making the E curved surface with the inclined-plane comes for example, it can design like this, the operating angle γ of slide block and rolling element 1 (roller, needle roller etc.) equals β and adds Ψ, the β angle is the minimum operating angle between lever block C curved surface and the rolling element 1, and the Ψ angle is the friction self-locking angle (as shown in Figure 8) between lever block working curved surface C and the rolling element 1.But the γ angle must be greater than the friction self-locking angle between slide block and the rolling element 1, makes the slide block must not self-locking when return.Rolling element 1 self-locking is not moved (except the rotation of rolling element self) with the E curved surface generation of slide block in the time of can guaranteeing break work (braking) like this, and during brake off slide block return, rolling element 1 does not produce self-locking with slide block, slide block can make things convenient for and easily is moved to the left return, and the drive lever block rotates return, break brake off.So just bring a huge breakthrough, both the operating angle of lever block afterbody C curved surface can be significantly smaller than the friction self-locking angle of it and rolling element 1 (operating angle originally must be greater than from the locking angle, slide block could become flexible return), self-locking return problem when no longer considering return after the braking work between C curved surface and the rolling element 1, the boosting function of C curved surface can significantly improve when the identical appearance size like this, the braking force of this break is significantly improved (generally more having manyed than high the getting of braking force of drum brake and conventional hydraulic disk type braker) than my the original braking force of patent scheme raising more than 40%.Because rolling element 1 becomes flexible return with slide block earlier, then become flexible return with lever block C curved surface again.When not strengthening zero portion difficulty, can guarantee reliable return and significantly improve braking force that this point is particularly important to break like this, brake for motorcycle can reduce total volume when satisfying onesize braking force, reduce cost, significantly improve reliability.It is bigger to the benefit that automobile brings.On automobile, it does not need vacuum servo system, can check car requirement in accordance with regulations, significantly reduce cost and eliminated the danger that the motor accident extinguishing brings braking force to reduce even disappears and bring, it also can do the Parking of car simultaneously and emergency stopper uses, and hand brakingly when driving both can check the car in travelling.When automobile running middle rolling car break (foot brake) lost efficacy, hand brake can get off car to car brake by the level of foot brake like this, and existing other break of this point can not accomplish, can make the Security of car improve 1.5 times after using it.It is except being used for the dolly, and it can also be used for all size lorry.And drum brake also needs power assist just can be used for lorry, because drum brake has two big shortcomings of heat fade and water fade, but because existing hydraulic brake braking force little (the usefulness factor is low), though it does not have this two shortcomings, but it can not be used for various lorries, people are trying every possible means to replace it with disk type braker, and the mechanical disc-type brake of this powerful high reliability occurs, come hope for Security generation of improving automobile undoubtedly, thereby it is state-of-the-art in the world break.I am by this scheme trial-production car sample.The working curved surface of various slide blocks and rolling element 1 is asked for an interview accompanying drawing 22-25 and this paper at last about the explanation of accompanying drawing 22-25.
Not adopting such as original my patent scheme increases D and E curved surface on the slide block, and rolling element only is set between slide block and C curved surface, and when not establishing rolling element between slider bottom and the piston groove (as shown in Figure 9), for guaranteeing reliably not self-locking return of slide block, generally about 20 degree, its force increasing ratio is about 2.7 at the minimum operating angle β angle of at this moment general C curved surface.And adopt the slide block of D curved surface and E curved surface, E curved surface is 23 when spending, and the operating angle of C curved surface can be about 13 degree, and at this moment force increasing ratio is 4.33, and force increasing ratio has increased by 60%.For further increasing the boosting function of C curved surface, promptly further reduce the β angle, when guaranteeing return reliable again, except the degree of finish that improves each component, can also change rolling friction (as shown in Figure 10) into by sliding friction dress rolling element in each motion place.As between at the bottom of slide block and the piston groove, adorning rolling element (as needle roller etc.), both reduced from locking angle α, can improve the force increasing ratio of curved surface C so again.At the A of lever block curved surface place dress rolling element (as roller bearing, needle roller, steel ball etc.), can reduce eccentric amount e like this, from and can significantly improve force increasing ratio or reduce break and the volume of clutch.Certainly this will come to determine as required.Certainly the C curved surface also can be designed to two sections or several sections, and with the better satisfied needs that use, as shown in Figure 11, the operating angle of lever block is divided into three section, first section C
1Operating angle β
1Maximum, at this moment available less slide block working stroke makes lever block obtain big rotation angle, eliminates the gap between brake shoe and the brake disc rapidly, does not at this moment also need bigger boosting function.Second section C
2Operating angle β
2Less than β
1, boosting function is greater than C
1Section, at this moment body is in the initial stage of resiliently deformable, the comparable C of required boosting function
3Section is little.For satisfying the needs that continue to increase braking force, steering force is controlled in the reasonable range, the 3rd section working curved surface C
3Operating angle β be minimum, the boosting function maximum.Save control run like this, in short control run, satisfied needs, also reduced the volume of break.Certainly also can be multistage more to the C curved design, can also be designed to continuous curved surface as shown in Figure 12.The situation of groundwork curved surfaces such as A, B, C also has detail to describe in original patent (98808763.4).For the motion of anti-limited slip block when braking exceeds the C curved surface, should note lever block tail dimension H during design, when making slide block also not move to the K of the end place point of C curved surface, the last planar ends L of the place point of lever block promptly contacts with the bottom surface of thread plate, thereby guaranteed that slide block is not drawn out, improved reliability (as shown in Figure 13).Also can design like this, when slide block does not also move to the K of the end place point of C curved surface when braking, bump 0 place, last plane of lever block promptly contacts with the lower plane of thread plate, and eccentric point at this moment is 0 place, does not work and roller is not re-used as the fulcrum of lever, roller and thread plate bottom surface produce the gap, throw of eccentric increases greatly, and boosting function descends greatly, and slide block is moved to the left some distances, the distance that piston moves down increases greatly, thereby makes the automatic compensation can more reliable (as shown in Figure 14).Also can be at the end of C curved surface C
4Design one section big operating angle β, and do not adopt the method that increases throw of eccentric to reach above-mentioned order ground (as shown in Figure 15).The minimum operating angle β span of C curved surface can be selected between the 70-3 degree.And the operating angle span of E curved surface can be selected between the 45-10 degree.The position (as shown in Figure 5) of rolling element 1 when fluting limits and do not work on when design can be with steel disc.Certain above-mentioned design all should be selected its parameter and structure for use according to concrete vehicle, and to reach optimum efficiency, this point these professional engineers and technicians all can accomplish.
After making slide block brake off return, the roller of adorning on the lever block all can produce enough big gap with the bottom surface of thread plate, to guarantee that automatic compensator can accurately compensate, on piston head, respectively adorned a location stage clip with screw, concrete condition is seen shown in the accompanying drawing 16-17, one end of stage clip inserts to be pushed down lever block and shelves and lives roller and can not move axially in the hole of lever block, the middle part of stage clip is pushed down by screw, and its other end is pushed down the last afterbody of lever block.Like this behind the slide block return, lever block and the slide block stage clip that all is positioned is pushed down the location, can not resemble to deenergize free movablely, has solved the phenomenon that drags that structure in the past still has behind the brake off sometimes.And make roller and thread plate bottom gapped all the time, thereby significantly improved the functional reliability of automatic compensator.For improving the reliability of automatic compensator again, on thread plate, can use and chamfer buttress thread form, as shown in Figure 18, strength and stiffness have been improved like this, and reduced rubbing surface between the screw thread, thus reduced surface friction drag, improved the reliability of automatic compensator again.
For improving the reliability of automatic compensator more, can adopt turriform garden steel wire torsion spring, turriform clockwork spring torsion spring, garden post torsion spring that pitch is bigger, as shown in Figure 19.It produces one to the pressure that presses down thread plate like this, (two faces do not have the gap when braking thereby the buttress thread form plane (stress surface) that makes thread plate and body screw thread plane produce the gap when needs compensates, and rotational resistance is also bigger), a cluster spring also can be set in addition apply a downward strength (as shown in Figure 20) to thread plate specially, thereby reach above-mentioned order ground, thereby make the easier rotation compensation of thread plate.
This break can be widely used on various motorcycles and the various automobile, scheme of erection shown in the accompanying drawing 1 is exactly a kind of mechanical disc brake for motorcycle, the mode that is used for transmission service brake steering force on the automobile can adopt hydraulic way, can adopt the mode of double-piston for the length that increases the lever block afterbody.Accompanying drawing 4 is the general assembly sketch of automobile with break.This structure also can be used on the clutch, as shown in Figure 21.
