Description
The present invention is the new-type brake that is mainly used in vehicle, particularly bicycle.
The handlebar of the various F-SPs of the non-flat wushu 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 rope and rope slings 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 the lock of pliers shape.The advantage of this 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 lock 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 rope and rope sling assembly set rigidity are relatively poor, and transmission power is bigger, cause distortion bigger, cause the consumption of brake lever stroke big, stroke utilizes insufficient, and resistance is also big, its steel rope 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 will be often change steel rope and making troubles more, and increase cost of repair.This inefficacy often takes place when sudden stop, brings safety hazard to the bicyclist.
The present invention improves brake assemblies and manipulation assembly, illustrates with Fig. 1 to Fig. 5.
The present invention sticks the double lever type booster that has installed additional during effective resistance is put at the pincerlike lock lock of brake assemblies.See Fig. 1, because lever 1 and upper lever 2 have been formed this booster.Hole 1a(or hole 2a) be resistance hole, place fulcrum hole 1b(or 2b on the lever) and power hole 1c(or 2c) between the somewhere, each fulcrum hole 1b and 2b are connected with attaching parts 4 with packing ring 3 backs in then at interval.For making left and light brake fork be convenient to install this booster, the distance between two holes on its lug is designed to littler than common pincerlike lock.See Fig. 2 or Fig. 3, the lughole 5a of left side lock fork 5 and the lughole 6a of right brake fork (6) be the less distance of tool, lughole 5a(or 6a) axial line and the fulcrum hole 5b(of left lock fork or the fulcrum hole 6b of right brake fork) axial line between angle of cut α can change.When α=0 °, be aclinal.Pairing back, arbitrary hole among arbitrary hole among the lughole 5a of aclinal and the lughole 6a and resistance hole 1a and the resistance hole 2a is connected it with attaching parts, promptly becomes parallel type double lever type booster shown in Figure 2; When α ≠ 0 °, promptly become chiasma type double lever type booster shown in Figure 3 (when α=90 °, then becoming vertical-type double lever type booster).When the steel rope of the power hole 1c of this booster or 2c and transmitting assembly or rope sling connect respectively good after, the power that is transmitted by steel rope or rope sling 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, wire rope transfers power just can reduce 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 chiasma type or vertical-type reduces, thereby it is restricted but transmitting assembly length is reduced to be loaded on the car body space lateral dimension, the crooked part that reduces, like this, relative deformation and the loss of transmission power also reduce.
The present invention is that the bigger existing old cable brake of distance that left and light brake is stuck between the lughole also can install this type of booster additional, resistance hole 1a that can be on booster and 2a(or one of them) each dress is as the connecting rod 7 of Fig. 4, be connected with attaching parts with it with the hole 7a on the connecting rod 7, be connected with attaching parts with the lughole of existing old cable brake lock fork with the hole 7b on each connecting rod 7 again.
As Fig. 5, distance value between the brake lever screw hole 8a of the brake lever 8 of manipulation assembly of the present invention and the 8b center, steel rope top connection hole equals this value on the existing cable brake, or greater than this value (promptly get existing 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 rope and rope sling, resistance reduces, thereby the possibility of bursting apart more can reduce, and distortion simultaneously reduces, and the loss of travel of brake lever 8 reduces, and its effective travel improves relatively.
Though transmitting assembly transmit power constant or even reduce because that booster reinforcement multiple can be designed to is bigger, so it is about more than 50 percent finally but can to improve brake weight generally speaking.
The present invention's embodiment is exemplified below:
One, front brake scheme:
(1) new check scheme:
As Fig. 6, the distance between the center of the center of steel rope top connection hole 8b and brake lever screw hole 8a this size than common 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 common cable brake.Adopted by upper lever 2 and following lever 1 part such as grade and formed parallel type double lever type booster.The middle resistance hole 2a of upper lever 2 and the lughole 6a of right brake fork 6 are connect by screw 12, nut 11 etc., and the lughole 5a of the middle resistance hole 1a of following lever 1 and left lock fork 5 is then connect by screw 10 and nut 9 etc.Each power hole 2c of an end of lever and 1c have replaced two holes on the common cable brake lock furcula ear up and down, and be similar with common cable brake, in order to lay carriage 23(and set screw 22) and tight rope screw 25.The other parts of lock are identical with common cable brake.When brake lever 8 is subjected to equal when clutching power, the power that this new cable brake steel rope 21 transmits is being much smaller than common cable brake just, thereby also few many of the distortion of steel rope 21 and rope sling 20, but finally be delivered to behind the double lever type booster because the boosting function of upper lever 2 and following lever 1, stressed just big many than common cable brake of the lughole 5a of left and light brake fork 5 and 6 and 6a, thereby with screw 29 and 14 and the gripping power that is fixed in brake rubber block 32 in the preceding brake rubber box 31 and 16 on the left and light brake fork 5 and 6 and 17 pairs of wheel steel rings with nut 30 and 15 much bigger than common cable brake just, it is also just much bigger to kill car power, and the possibility of bursting apart of steel rope 21 but can reduce many.
(2) old lock modification scheme:
Existing common cable brake also can install the lever booster additional, but because the distance between the lug of left and light brake fork is excessive, so the resistance hole 2a of the lever up and down on it and 1a(or one of them) on to install connecting rod 7 additional, with each connecting rod 7(or one of them) the hole 7a that goes up is connected with attaching parts with resistance hole, connect (reduce the power that steel rope and rope sling were transmitted as also wishing, then also need replace brake lever and support thereof) with the hole 7b of each connecting rod (or one of them) other end and the lughole of left and light brake fork (or one of them) with attaching parts again.(figure slightly)
Two, back brake scheme:
(1) be loaded on the upright scheme of sticking of vehicle frame:
As Fig. 7, the brake assemblies of manipulation assembly that brake lever 8 grades are formed and pincerlike lock 33 and parallel type double lever type booster 34 compositions is the same substantially with new cable 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 rope 21 of transmitting assembly and rope sling 20 will be grown, as be used for the then middle part of steel rope 21 and rope sling 20 placement that also will descend of woman style car.Like this, the installation site is the same with old cable brake back brake, brake weight and anti-collapse performance and can obtain bigger improvement than but with old cable brake back brake, but with new front brake ratio, gap is also bigger.
(2) be loaded on scheme on the seat tube:
1, be loaded on scheme outside the pedal crank up scope:
As Fig. 8, manipulation assembly that brake lever 8 grades are formed and the brake assemblies formed with pincerlike lock 33 and parallel type double lever type booster 34 are the same substantially with new cable 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 rope 21 of transmitting assembly and rope sling 20 longer look seldom, and can not have bending near double lever type booster 34 places, thereby the loss of transmission power is just not too large, kill car power and the anti-ability of collapsing can improve relatively more, not only good than old cable brake back brake, and comparatively approaching front brake newly.
2, be loaded on scheme within the pedal crank up scope:
As Fig. 9, manipulation assembly that brake lever 8 is formed and new cable brake front brake the same substantially, but the lever booster 34 in the brake assemblies is vertical-types, 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 37, nut 38 and packing ring 39 etc., distance between the lughole 5a of the lughole 6a of right brake fork 6 and left lock fork 5 is also less, and hole 5a(or 6a) axial line be perpendicular to fulcrum hole 5b(or 6b) axial line.The middle resistance hole 1a of the following lever 1 of double lever type booster 34 and the lughole 6a of right brake fork 6 are by screw 43, nut 44 and overlap 45 and be tied, and the lughole 5a of the middle resistance hole 2a of upper lever 2 and left lock fork 5 is by screw 46, nut 47 and overlap 48 and be tied.The vertical-type double lever type booster of Zu Chenging like this, the other end and the same of parallel type of lever also respectively have a power hole so that be connected with transmitting assembly up and down for they, but because brake assemblies is in lower position, so the length of steel rope 21 and rope sling 20 increases few and can remove bending near the brake assemblies place, the loss of transmission power is just few, kill car power and anti-collapse performance can improve relatively equally more, thereby not only good than old cable brake back brake, and also can be comparatively near new front brake.
(3) old lock modification scheme:
The same with one (two).
