The present invention adopts the measure that a double-lever type reinforcement device which is composed of an upper and a lower lever 2, 1, etc., and is in an effective resistance device is additionally installed on a left brake fork 5 and a right brake fork 6, thereby, the clamping force finally obtained by the left brake fork 5 and the right brake fork 6 of a clamping brake is much more than that of a common caliper brake. The present invention has the capability of puissant brake and collapse prevention. Meanwhile, the present invention can also adopt the measure of enlarging the distance between the center of a joint on a steel wire and the center of a screw of a brake handle to reduce the stress, the resistance and the transformation of the steel wire 21 and a wire loop 20. The present invention further increases the braking force and the operation mileage rate of the brake handle, and meanwhile, the collapse prevention capability is improved.
Description
The present invention is the pincerlike lock that is mainly used in vehicle, particularly bicycle.
The handlebar of the various F-SPs of increasing employing such as the bicycle of producing or other vehicle at present.Often being equipped with the assembly that also can only be equipped with compositions such as steel cable and steel rope sleeves for the handlebar of various F-SPs is that the assembly of transmitting assembly and composition such as brake lever that adapt with it is the manipulation assembly, and its brake assemblies then is pincerlike lock mostly.Pincerlike lock of 3.13.2 and 3.14.2 in " GB3582-83 caliper brake for bicycle ", " the GB3564-83 bicycle part is unified title "
Each joint of pincerlike lock is described to this, and the pincerlike lock of the bicycle use of selling on the market so far also is this structure basically.The advantage of this existing pincerlike cable brake structure is that good looking appearance is light and handy again, and simple structure and be independent of the other parts of vehicle, thereby also is easy to make, and is easy to loading and unloading, cheap, is difficult for undermining other parts on the car when sudden stop.But it is less and be difficult to change that this existing pincerlike cable brake changes the hand power of pinching in the process of gripping power reinforcement at it, makes the brake weight shortcoming that seems, its back brake is even more serious.Steel cable and steel rope sleeve assembly set rigidity are relatively poor, and transmission power is bigger, cause distortion bigger, cause explaining stroke consumption big, stroke utilizes insufficient, and resistance is also big, its steel cable is close to top connection place and is easy to burst apart, or when top connection is welded structure then easily sealing-off lost efficacy, make the user often to change steel cable and make troubles, and increase cost of repair.This inefficacy often takes place when sudden stop, brings safety hazard to the bicyclist.
Thereby the purpose of this invention is to provide a kind of keep the advantage of existing pincerlike cable brake and increase gripping power increase brake weight and (or) avoid the possible strong wire-controlled brake that bursts apart as far as possible.
The object of the present invention is achieved like this, brake assemblies and manipulation assembly are improved, two kinds of technical measures have promptly been adopted: first, to the power transmission process of pincerlike lock fork, set up a double lever type booster of forming by upper lever and following lever at brake lever, in order to increase the gripping power of pincerlike lock lock fork; The second, the distance between brake lever screw hole axial line on the brake lever and the steel cable top connection hole axial line is increased, in order to reduce the suffered power of steel cable.As the case may be and requirement, these two kinds of technical measures can be distinguished separately and implement, but also common implementing.Illustrate with Fig. 1 to Fig. 5.Fig. 1 is the front view and the left view of double lever type booster.Fig. 2 is the brake assemblies front view and the right elevation of band parallel type double lever type booster.Fig. 3 is the brake assemblies front view and the right elevation of band chiasma type (vertical-type) double lever type booster.Fig. 4 is the front view of connecting rod.Fig. 5 is a cutaway view of handling assembly.
The double lever type booster during effective resistance is put had been installed in the present invention additional before the pincerlike lock lock fork of brake assemblies.See Fig. 1, by lever 1 and upper lever 2 have been formed this booster down.Hole 1a (or hole 2a) is a resistance hole, places on the lever somewhere between the fulcrum hole 1b (or 2b) and power hole 1c (or 2c), and each fulcrum hole 1b and 2b are connect with joint piece 4 with packing ring 3 backs in then at interval.For making the left and light brake fork be convenient to install this booster, the distance between two holes on its lug is designed to than having the littler of pincerlike cable brake.See Fig. 2 or Fig. 3, the lughole 5a of left lock fork 5 and the lughole 6a of right brake fork 6 be the less distance of tool, and the angle of cut α between the axial line of the axial line of lughole 5a (or 6a) and the fulcrum hole 5b of left lock fork (or fulcrum hole 6b of right brake fork) can change.When α=0 °, be aclinal.Pairing back, arbitrary hole among arbitrary hole and resistance hole 1a and the resistance hole 2a among the lughole 5a of aclinal and the lughole 6a is connect it with joint piece, promptly become as shown in Figure 2 brake assemblies with parallel type double lever type booster; When α ≠ 0 °, promptly become as shown in Figure 3 brake assemblies with chiasma type double lever type booster (when α=90 °, then becoming the brake assemblies of band vertical-type double lever type booster).When the power hole 1c of this booster or 2c replace the steel cable of folder earhole and transmitting assembly on the existing pincerlike cable brake or steel rope sleeve with have the identical method of pincerlike cable brake connect respectively get well after, the power that is transmitted by steel cable or steel rope sleeve just obtains gain, makes the gripping power of left and light brake fork 5 and 6 increase to certain designated value by pre-provisioning request.Otherwise as not increasing with gripping power, steel cable transmits power just can be reduced relatively, and what it burst apart may also just can reduce.The lateral dimension of lock fork (comprising booster) on its lock fork plane that can make of band chiasma type or band vertical-type reduces, thereby it is restricted but wish that transmitting assembly length reduces to be loaded on the car body space lateral dimension, the crooked minimizing, i.e. relative deformation and transmission power loss wishes to reduce part.
The present invention is that the bigger existing pincerlike cable brake of distance that left and light brake is stuck between the lughole also can install this type of booster additional, each dress of resistance hole 1a that can be on booster and 2a (or one of them) is as the connecting rod 7 of Fig. 4, connect with joint piece with the hole 7a on the connecting rod 7 and its, the lughole of explaining the lock fork with hole 7b on each connecting rod 7 and existing pincerlike line connects with joint piece again.
As Fig. 5, place the brake lever screw hole 8a of the brake lever 8 in the brake lever support 9 and the distance value between the 8b center, steel cable top connection hole to equal this value on the existing pincerlike cable brake in the manipulation assembly of the present invention, or greater than this value (promptly get existing pincerlike cable brake on this is worth to certain value between the 60mm), also change thereupon of relevant size on the brake lever support simultaneously.After this value increases, can make the stressed minimizing of steel cable and steel rope sleeve, resistance reduces, thereby the possibility of bursting apart can reduce, and distortion simultaneously reduces, and the loss of travel of brake lever 8 reduces, and its effective travel improves relatively.
The present invention is except that above-mentioned improvement, and in addition parts and relation therebetween be still as have the pincerlike cable brake for all the other.Like this, overall structure of the present invention is mainly by brake lever 8 and brake lever support 9, steel cable 21 and steel rope sleeve 20, or the double lever type booster (or increasing by one or two connecting rod 7 again) that adds upper lever 2 and play lever 1 to form, left side lock fork 5 and right brake fork 6 add the captive nut that lock fork spring and stepping brake fork spring are used, and brake rubber box and brake rubber block connect successively and form.
The present invention has the advantage of pincerlike cable brake except still keeping, and its good effect is tangible.Because booster has been arranged, lock fork gripping power increases a lot, so brake weight can improve greatly.Because what the stressed minimizing of steel cable, steel cable were burst apart may just greatly reduce.If said two devices share, can offset the minimizing of steel cable transmission power has a surplus owing to the booster reinforcement effect, so under the general optimum structure design situation, it is about more than 50 percent finally can to make the increase of brake lever stroke not improve gripping power for a long time, otherwise, if do not increase gripping power, then obtain the labour-saving effect.
The present invention's embodiment is exemplified below: one, front brake scheme:
(1) new check scheme:
As Fig. 6, be that new check conceptual view of front brake and A are to view and A-A section (amplification) figure, distance between the center of the center of steel cable top connection hole 8b and brake lever screw hole 8a this size than existing pincerlike cable brake is big, and the distance between the lughole 5a of the lughole 6a of right brake fork 6 and left lock fork 5 is littler than this size on the existing pincerlike cable brake.Adopted by upper lever 2 and following lever 1 part such as grade and formed parallel type double lever type booster.The lughole 5a of the middle resistance hole 1a of lever 1 and left lock fork 5 was all connect by screw 11 and nut 10 etc. under the middle resistance hole 2a of upper lever 2 and the lughole 6a of right brake fork 6 reached.Each power hole 2c of an end of lever and 1c have replaced two holes on the existing pincerlike cable brake lock furcula ear up and down, and be similar with existing pincerlike cable brake, in order to lay carriage 23 (with set screw 22) and tight rope screw 25.The other parts of lock are identical with existing pincerlike cable brake.When brake lever 8 is subjected to equal when clutching power, the power that this strong wire-controlled brake steel cable 21 transmits is being much smaller than existing pincerlike cable brake just, thereby also few many of the distortion of steel cable 21 and steel rope sleeve 20, but finally be delivered to behind the double lever type booster because the boosting function of upper lever 2 and following lever 1, the lughole 5a of left and light brake fork 5 and 6 and 6a are stressed just than having the big many of pincerlike cable brake, thereby the gripping power of the 17 pairs of rims of brake rubber block in the brake rubber box 16 be fixed in left and light brake fork 5 and 6 with screw 14 with nut 15 on is just than having the much bigger of pincerlike cable brake, brake weight is also just much bigger, and the possibility of bursting apart of steel cable 21 but can reduce many.
(2) the existing pincerlike cable brake modification scheme in the use:
Existing pincerlike cable brake in the use also can install the lever booster additional, but because the distance between the lug of left and light brake fork is excessive, so will install connecting rod 7 additional on the resistance hole 2a of the lever up and down on it and the 1a (or one of them), connect again hole 7b with the connecting rod other end resistance hole of connecting rod (or be unkitted) with joint piece and the lughole of existing pincerlike cable brake lock fork connects (as also wishing the minimizing power that steel cable and steel rope sleeve were transmitted, then also need replace brake lever and support thereof) with joint piece with the hole 7a on the connecting rod 7 and resistance hole.(figure is slightly) two, back brake scheme:
(1) be loaded on the upright scheme of sticking of vehicle frame:
As Fig. 7, be that back brake is loaded on the upright conceptual scheme of sticking of vehicle frame, the brake assemblies 33 of manipulation assembly that brake lever 8 grades are formed and band parallel type double lever type booster is the same substantially with the strong wire-controlled brake front brake, but the vehicle frame that brake assemblies is loaded under the saddle 35 stands on the fork 36.Like this, it is many that the steel cable 21 of transmitting assembly and steel rope sleeve 20 will be grown, as be used for the then middle part of steel cable 21 and steel rope sleeve 20 placement that also will descend of woman style car.Like this, though its brake weight and the anti-performance that collapses are gone back some gap with strong wire-controlled brake front brake ratio, can similarly obtain bigger improvement with existing pincerlike cable brake back brake than still, and the installation site is still the same with existing pincerlike cable brake back brake.
(2) be loaded on scheme on the seat tube:
1, be loaded on scheme outside the pedal crank up scope:
As Fig. 8, be that back brake is loaded on the conceptual scheme outside the pedal crank up scope, the brake assemblies 33 of manipulation assembly that brake lever 8 grades are formed and the two lever type boosters of band parallel type is the same substantially with the strong wire-controlled brake front brake, but be loaded on seat tube 40 among with screw 39, nut 38 and packing ring 37 etc. brake assemblies or the back brake seat 41 on top on, make it to be in outside the pedal crank up scope.Like this, though the steel cable 21 of transmitting assembly and steel rope sleeve 20 are grown a little but are looked few, and can there be bending near parallel type double lever type booster place, thereby the loss of transmission power is just not too large, brake weight can improve more with the anti-ability of collapsing relatively, not only good than existing pincerlike cable brake back brake, and comparatively near the strong wire-controlled brake front brake.
2, be loaded on scheme within the pedal crank up scope:
As Fig. 9, be that back brake is loaded on the conceptual scheme in the pedal crank up scope, manipulation assembly that brake lever 8 is formed and strong wire-controlled brake front brake the same substantially, but have the brake assemblies 34 of being with vertical-type double lever type booster, can avoid the motion of pedal crank like this.Whole brake assemblies is loaded on the back brake seat 42 of seat tube 40 with screw 39, nut 38 and packing ring 37 etc., and the distance between the lughole 5a of the lughole 6a of right brake fork 6 and left lock fork 5 is also less.The lughole 5a of the middle resistance hole 2a of the middle resistance hole 1a of the following lever 1 of the vertical-type double lever type booster in the brake assemblies 34 and the lughole 6a of right brake fork 6 and upper lever 2 and left lock fork 5 is all by screw 43, nut 44 and overlap 45 and be tied.Like this, the vertical-type double lever type booster of forming, the other end and the same of parallel type of lever also respectively have a power hole so that connect with transmitting assembly up and down for they, but because brake assemblies is in lower position, so the length of steel cable 21 and steel rope sleeve 20 increases few and can remove bending near the brake assemblies place, the loss of transmission power is just few, brake weight and prevent that collapsing performance can improve more equally relatively, thereby not only good, and also can be comparatively near the strong wire-controlled brake front brake than existing pincerlike cable brake back brake.
(3) the existing pincerlike cable brake modification scheme in the use:
The same with one (two).
