At first, just Fig. 1～the 1st embodiment of the present invention shown in Figure 5 describes.
In Fig. 1, on the steering tiller 2 of the upper end of the car body 1 that is arranged at two-wheeled motor vehicle, be adjacent to pivot suspension with right handles 2a and independent brake bar 3, be adjacent to pivot suspension with left handle 2b and interlock brake rod 4.The interior wirerope 5a that connects independent brake operation wirerope 5 on independent brake bar 3, by operation independent brake bar 3, wirerope 5a is pulled in this.In addition, connect the interior wirerope 6a of interlock brake operating wirerope 6 on interlock brake rod 4, by operations linkage brake rod 4, wirerope 6a is pulled in this.
On the other hand, be equipped in front-wheel brake Bf on the front and back wheel of two-wheeled motor vehicle and rear wheel brake Br respectively and all be mechanical type drum brake mechanism by throw rod is moved, the interior wirerope 5a that on the throw rod 7f of front-wheel brake Bf, connects independent brake operation wirerope 5, the interior wirerope 6a of connection interlock brake operating wirerope 6 on the throw rod 7r of rear wheel brake Br.So, by the interior wirerope 5a of traction independent brake operation wirerope 5, front-wheel brake Bf action is by the interior wirerope 6a of traction interlock brake operating wirerope 6, rear wheel brake Br action.Each drg Bf, the throw rod 7r of Br, 7f is suppressed to non-direction of action by pull back spring 8f, 8r respectively.
Near independent brake operation wirerope 5 and interlock brake operating wirerope 6 position the head pipe 1h side of the car body 1 of two-wheeled motor vehicle is configured to almost parallel.Like this, in this position, be provided for that front and rear wheel brake Bf, Br are carried out separately or the linkage 9 of interlock action.Each outer wirerope 5b, 6b of independent brake operation wirerope 5 and interlock brake operating wirerope 6 is split into the outer wirerope 5b1 of input side respectively at the equipping position of this linkage 9, the outer wirerope 5b2 of 6b1 and outgoing side, 6b2.The outer wirerope 5b1 of input side, 6b1 is respectively, and the one end is supported on the steering tiller 2, and the other end is supported on the linkage 9 as described later.In addition, the outer wirerope 5b2 of outgoing side, 6b2 is respectively, and the one end is supported on the fixed panel of front and rear wheel brake Bf, Br, and the other end is supported on the linkage 9 as described later.
Can understand from Fig. 2 and Fig. 3, linkage 9 has wirerope holding member 13, this wirerope holding member 13 is to be made of case cylindraceous 10 that surrounds independent brake operation wirerope 5 and interlock brake operating wirerope 6 and a pair of cover 11,12 that seals its both ends of the surface.Each covers 11,12 the cylinder 14 and a pair of rings 15,15 of inner peripheral surface by being entrenched in case 10 and positions fixing.Like this, this wirerope holding member 13 is fixedly supported on the car body 1 by bolt 16,16.In addition, this wirerope holding member 13 is supported on the car body 1 with can being floating type.
In case 10, the retainer 18 with inserting hole 17,17 is set, wirerope 5a in each of independent brake operation wirerope 5 and interlock brake operating wirerope 6,6a can insert logical this inserting hole 17,17 with being free to slide.This retainer 18 can be free to slide the chimeric interior week that is supported on above-mentioned cylinder 14 of ground.Therefore, between the cover 11,12 of these retainer 18 at both endss, can slide at the axis direction of each wirerope 5,6.
The outer wirerope 5b1 of the input side of independent brake operation wirerope 5 is installed on the face of input side (right side among Fig. 2) of retainer 18.In addition, the outer wirerope 5b2 of this outgoing side is fixed on the cover 12 in outgoing side (left side among Fig. 2).On the other hand, the outer wirerope 6b1 of the input side of interlock brake operating wirerope 6 is fixed on the cover 11 of input side, and the outer wirerope 6b2 of outgoing side is installed on the face of outgoing side of retainer 18.So, the outer wirerope 6b2 of outgoing side of outer wirerope 5b1 of the input side of independent brake operation wirerope 5 and interlock brake operating wirerope 6 is installed in respectively on the face of opposition side of retainer 18, simultaneously, be fixed on the wirerope holding member 13 in mutual relative mode as the outer wirerope 5b2 of outgoing side of the independent brake operation wirerope 5 of the opposing party's outer wirerope and the outer wirerope 6b1 of input side of interlock brake operating wirerope 6.Have again, on the cover 11 and retainer 18 of input side,, between this spring retainer 19,20, be provided with them to repelling the hysteresis spring 21 that direction is suppressed respectively with mutual relative mode mounting spring retainer 19,20.Therefore, retainer 18 by to cover 12 position contacting of outgoing side, promptly non-operating position pushing is afterburning.
Then, effect that should the 1st embodiment describes.
When independent brake operation wirerope 5 and interlock brake operating wirerope 6 are non-action status, promptly, not to any one of independent brake bar 3 and interlock brake rod 4 when applying operating effort, by being separately positioned on front and rear wheel brake Bf, pull back spring 8f on the Br, 8r, wirerope 5a in each of independent brake operation wirerope 5 and interlock brake operating wirerope 6 suppressed in the left side of Fig. 2,6a.In addition, because the elastic force pressure of hysteresis spring 21, retainer 18 is cover 12 state of contact with outgoing side.
Because if under this state, operation independent brake bar 3, the interior wirerope 5a of traction independent brake operation wirerope 5, then this tractive force is delivered to the throw rod 7f of front-wheel brake Bf without change, so front-wheel brake Bf action.At this moment, though outer wirerope 5b1 at independent brake operation wirerope 5, produce its antagonistic force on the 5b2 respectively, but, because the outer wirerope 5b2 of outgoing side is fixed on the cover 12 of outgoing side, so can be because of this antagonistic force does not produce any variation, the cover 12 of this outgoing side is as a part that is fixedly supported on the wirerope holding member 13 on the car body 1.In addition, because the antagonistic force that produces on the wirerope 5b1 becomes the power to the cover 12 pushing retainers 18 of outgoing side, can not produce any variation outside input side because of this antagonistic force.Therefore, can not apply tractive force to the interior wirerope 6 of interlock brake operating wirerope 6, rear wheel brake Br can not move.
Like this, when operation independent brake bar 3, rear wheel brake Br is failure to actuate, only front-wheel brake Bf single movement.Like this, because if remove the operating effort of independent brake bar 3, then the throw rod 7f of front-wheel brake Bf returns to original position by the elastic force pressure of pull back spring 8f, so front-wheel brake Bf is a non-action status.
In addition, because if operations linkage brake rod 4, the interior wirerope 6a of traction interlock brake operating wirerope 6, then this tractive force is delivered to the throw rod 7r of rear wheel brake Br without change, so at first rear wheel brake Br action.Like this, at this moment, because the antagonistic force that outside the outgoing side of interlock brake operating wirerope 6, produces on the wirerope 6b2, outside this is installed on the retainer 18 of wirerope 6b2, applies and desire power that it is moved to the cover 11 of input side.But, this force rate be applied to by hysteresis spring 21 mobile limiting force on the retainer 18 little during, retainer 18 is retained as cover 12 state of contact with outgoing side.
If under this state, continue operations linkage brake rod 4, the antagonistic force that produces on the outer wirerope 6b2 of the outgoing side of interlock brake operating wirerope 6 is further increased, then desire to make power that retainer 18 moves to the cover 11 of input side above the mobile limiting force that produces because of hysteresis spring 21.So, retainer 18 moves to the cover 11 of input side, and the outer wirerope 5b1 of input side that is installed in the independent brake operation wirerope 5 on this retainer 18 is by the right pushing to Fig. 2.Its result also moves for front-wheel brake Bf, makes the interior wirerope 5a of independent brake operation wirerope 5 and the interior wirerope 6a of interlock brake operating wirerope 6 together be pulled.At this moment, retainer 18 moves to upper/lower positions, promptly with the making a concerted effort and position that the load of hysteresis spring 21 generations balances each other of the antagonistic force that produces on the outer wirerope 6b2 of the outgoing side of interlock brake operating wirerope 6.Therefore, the front-wheel brake Bf of this moment and the braking force of rear wheel brake Br become and the corresponding apportionment ratio of the elastic force of hysteresis spring 21.
Like this, if the operating effort of interlock brake rod 4 reaches the size of regulation, then as shown in Figure 4, retainer 18 contacts with the cover 11 of input side, stops retainer 18 moving more than this.Therefore, the braking force of front-wheel brake Bf can not be increased to more than this, and just the braking force of rear wheel brake Br increases later on.
Like this, when operations linkage brake rod 4, at first, rear wheel brake Br action, then, and after the some time, the front-wheel brake Bf action that links.In view of the above, because one side prevents the longitudinal vibration of vehicle, one side is roughly braking simultaneously of front and back wheel, so can carry out the braking stably of two-wheeled motor vehicle.Because if remove the operating effort of interlock brake rod 4, each throw rod 7f of front-wheel brake Bf and rear wheel brake Br then, 7r is by pull back spring 8f, and the elastic force pressure of 8r returns to original position, so front-wheel brake Bf and rear wheel brake all become non-action status.Like this, linkage 9 also returns to the state of Fig. 2.
As mentioned above, according to present embodiment, because be at each wirerope 5,6 axis direction is provided with slidably retainer 18, only by suitably with the outer wirerope 5b of each wirerope 5,6,6b is installed on this retainer 18 and is fixedly supported on the wirerope holding member 13 on the car body 1 and constitutes linkage 9, so can make this linkage 9 for compact device, in addition, can improve the degree of freedom of its configuration.In addition, because be to form these wirerope holding members 13, retainer 18 is housed in this case 10, so can prevent that moving part from exposing to the outside by case 10 cylindraceous and the cover 11,12 that seals its two ends.
Then, just Fig. 5～the 2nd embodiment of the present invention shown in Figure 7 describes.
Because in the 2nd embodiment, the wirerope holding member that only is formation linkage 9 is different with the 1st embodiment, and other formation is same as the previously described embodiments, so in the drawings, by to paying identical symbol, and omit its explanation with the corresponding part of the foregoing description.
As Fig. 5 and shown in Figure 6, under the situation of the 2nd embodiment, linkage 9 has and the bar 23 of independent brake operation wirerope 5 and interlock brake operating wirerope 6 configured in parallel and the wirerope holding member 26 that is made of a pair of plate 24,25 that is fixedly supported on its both ends.The end difference 23a at the both ends of each plate 24,25 by being formed on bar 23,23a and be fastened on the threaded portion 23b at two ends, the nut 27,27 of 23b positions and is fixed.Like this, this wirerope holding member 26 is fixedly supported on the car body 1 by the carriage 28 on the plate 24 that is fastened on a side jointly.In addition, this wirerope holding member 26 also can be floating type and is supported on the car body 1.
Between the plate 25 of the plate 24 of input side (right side among Fig. 5) and outgoing side (left side among Fig. 5), retainer 29 is set.This retainer 29 can be supported on the bar 23 by the slide bushing 30 chimeric with bar 23 with being free to slide.Therefore, between the plate 24,25 of these retainer 29 at both endss, can slide at the axis direction of each wirerope 5,6.
Like this, identical with the 1st embodiment, the outer wirerope 5b1 of the input side of independent brake operation wirerope 5 is installed on the face of input side of this retainer 29, and the outer wirerope 6b2 of outgoing side of interlock brake operating wirerope 6 is installed on the face of outgoing side.In addition, the outer wirerope 5b2 of outgoing side of independent brake operation wirerope 5 is fixed on the plate 25 of outgoing side, and the outer wirerope 6b1 of input side of interlock brake operating wirerope 6 is fixed on the plate 24 of input side.On the plate 25 of outgoing side, setting can be supported the slide bushing 31 of the outer wirerope 6b2 of outgoing side of interlock brake operating wirerope 6 with being free to slide.Like this, outside this, on the wirerope 6b2, the block 32 that contacts with the plate 25 of outgoing side is set.
Have again, between the plate 24 and retainer 29 of input side, be provided with them to repelling the hysteresis spring 33 that direction is suppressed.Therefore, retainer 29 by to plate 25 position contacting of outgoing side, promptly non-operating position pushing is afterburning.
Even in linkage braking device with such linkage 9, if operations linkage brake rod 4 (with reference to Fig. 1), the interior wirerope 6a of traction interlock brake operating wirerope 6, then rear wheel brake Br action, simultaneously, by the antagonistic force that produces on the wirerope 6b2 outside the outgoing side of this interlock brake operating wirerope 6, retainer 29 applied desire power that it is moved to the plate 24 of input side.Like this, if the antagonistic force that produces on the outer wirerope 6b2 of the outgoing side of interlock brake operating wirerope 6 is greatly to the load of setting on hysteresis spring 33 when above, then retainer 29 moves to the plate 24 of input side, and wirerope 5b1 is by the right pushing to Fig. 5 outside the input side of the independent brake operation wirerope of installing on this retainer 29 5.Therefore, the interior wirerope 5a of this independent brake operation wirerope 5 is pulled, front-wheel brake Bf action.
Like this, if the operating effort of interlock brake rod 4 reaches the size of regulation, then as shown in Figure 7, the block 32 that is arranged on the outer wirerope 6b2 of outgoing side of interlock brake operating wirerope 6 contact with the plate 25 of outgoing side, prevention retainer 29 mobile more than this.Therefore, the braking force of front-wheel brake Bf can not be increased to more than this, and just the braking force of rear wheel brake Br increases later on.
Like this, even according to the 2nd embodiment, also can obtain the action effect identical with the situation of the 1st embodiment.Like this, when the 2nd embodiment is suppressed to less situation at the outside dimension with linkage 9, effective especially.
Then, Fig. 8～the 3rd embodiment of the present invention shown in Figure 14 is described.
Though the 3rd embodiment is the embodiment that uses hydraulic brake on the side of front and rear wheel brake Bf, Br, because basic formation is identical with the 1st embodiment, so in the drawings, to paying identical symbol with the corresponding part of the 1st embodiment.
In Fig. 8, on the steering tiller 2 of the upper end of the car body 1 that is arranged at two-wheeled motor vehicle, independent brake bar 3 in abutting connection with the ground pivot suspension with right handles 2a, interlock brake rod 4 with left handle 2b in abutting connection with the ground pivot suspension.Independent brake bar 3 makes front-wheel brake Bf single movement by its operation, and interlock brake rod 4 makes front-wheel brake Bf and rear wheel brake Br interlock action by its operation.The fluid pressure type plate disc brake of front-wheel brake Bf for moving by the hydraulic pressure that flows to caliper body 35, the mechanical type drum brake mechanism of rear wheel brake Br for throw rod 7r being moved by the tractive force that utilizes operation wirerope 6.The throw rod 7r of rear wheel brake Br is suppressed to non-direction of action by pull back spring 8r.
Like this, in order to make the independent or interlock action of front and rear wheel brake Bf like this, Br, independent brake operating system A and interlock brake-operating system B are set on this linkage braking device.Independent brake operating system A is made of independent brake bar 3, independent brake operation wirerope 5, total cylinder 36, hydraulic piping 37 and caliper body 35.In addition, interlock brake-operating system B is by interlock brake rod 4, interlock brake operating wirerope 6 and throw rod 7r, constitutes with shared total cylinder 36, hydraulic piping 37 and the caliper body 35 of independent brake operating system A.
The operation wirerope 5 of independent brake operating system A is made of interior wirerope 5a and outer wirerope 5b.Should be connected with independent brake bar 3 by interior wirerope 5a one end, by operation independent brake bar 3, wirerope 5a is pulled in this.Outer wirerope 5b one end is supported on the steering tiller 2, and simultaneously, the other end is supported on total cylinder 36 as described later.On the other hand, the operation wirerope 6 of interlock brake-operating system B is made of interior wirerope 6a and outer wirerope 6b.Should be split into outer wirerope 6b1 of input side and the outer wirerope 6b2 of outgoing side by outer wirerope 6b.Interior wirerope 6a is that the one end is connected on the interlock brake rod 4, simultaneously, continuous 1 of the throw rod 7r bonded assembly of the other end and rear wheel brake Br, by operations linkage brake rod 4, this interior wirerope 6a is pulled.Like this, the outer wirerope 6b1 one end of input side is supported on the steering tiller 2, simultaneously, the other end as described later, be supported on the linkage 38, the outer wirerope 6b2 one end of outgoing side is supported on the fixed panel of rear wheel brake Br, simultaneously, the other end is supported on the linkage 38 as described later.
On diapire 41a on the cylinder hole 41, the communication port 45 that is communicated with hydraulic pressure chamber 43 is set, on this communication port 45, connecting above-mentioned hydraulic piping 37.In addition, on the perisporium of the above-below direction central portion in cylinder hole 41, be provided with and container 46 (with reference to Fig. 8) bonded assembly supply mouth 47.
In the bottom of the cylinder main body 40 of total cylinder 36, (among Figure 10 right-hand) is provided with pivot shaft 48 at the rear in cylinder hole 41.Like this, on this pivot shaft 48, rotatably supporting and hitting lever arm 49 and forearm 50.Hit on the lever arm 49 at this, on the part relative, form the 49a of the bar portion of hitting that promotes this piston 42 with the piston 42 of total cylinder 36.This hits the 49a of bar portion when hitting lever arm 49 non-actions, is held with the lower surface state of contact with piston 42.In addition, in the rearward end of hitting lever arm 49, the stopper portions 51 that contacts with the back side of cylinder main body 40 is set.
On the other hand, as Fig. 9 and shown in Figure 12, forearm 50 is that the front of 1 metal sheet is partly turned back, and devices spaced apart forms relative pair of sidewalls, overlooks being roughly J word shape, and its fore-and-aft direction pars intermedia can contact with the leading section that hits lever arm 49.On the leading section of this forearm 50, be connected with the interior wirerope 5a of independent brake operation wirerope 5.In addition, support the outer wirerope 5b of this independent brake operation wirerope 5 support portion 52 that is set at the leading flank of cylinder main body 40.So, in the operation by independent brake bar 3, during the interior wirerope 5a of traction independent brake operation wirerope 5, forearm 50 is that rotate in the clockwise direction at the center with pivot shaft 48.
As Fig. 9 and shown in Figure 11, on the cylinder main body 40 that is fixed in the total cylinder 36 on the car body 1,, the input side support portion 53 of the outer wirerope 6b1 of input side of fixed pedestal interlock brake operating wirerope 6 is set, i.e. the wirerope holding member on its lateral surface top.In addition, lateral surface bottom in cylinder main body 40, be provided with by slide bushing 54, support the retainer support portion 56 of retainer 55 slidably, block nut 58 this retainer support portion 56, that contact with 53 side end faces, input side support portion is screwed on the retainer 55, between this block nut 58 and input side support portion 53, state with the compressive load that applies regulation, hysteresis spring 57 is set, suppresses retainer 55, its left side to Fig. 9 is moved.Retainer 55 be configured to from the below with hit lever arm 49 and contact.In the bottom of retainer 55, the outer wirerope 6b2 of outgoing side of interlock brake operating wirerope 6 is installed.
In addition, above-mentioned input side support portion 53 is not must be arranged on total cylinder 36, can be arranged on the car body 1 near total cylinder 36 yet.Mainly be that input side support portion 53 is set to can not getting final product by relative displacement with total cylinder 36.
Then, the effect to the 3rd embodiment describes.
Because when independent brake operating system A and interlock brake-operating system B all are in non-action status, the piston 42 of total cylinder 36 is pushed downwards by pull back spring 44, so lower surface by this piston 42, hit lever arm 49 to anticlockwise motion, the stopper portions 51 of hitting the rearward end of lever arm 49 is in the back side state of contact with cylinder main body 40.That is, piston 42 is maintained at lower position.Like this, at this moment, as shown in figure 10, the 49a of the bar portion of hitting that hits lever arm 49 contacts with the lower surface of piston 42.
Because if under this state, operation independent brake bar 3, the interior wirerope 5a of traction independent brake operation wirerope 5, then owing to this tractive force, forearm 50 is the center with pivot shaft 48, rotate to clockwise direction, so as shown in figure 13, by being arranged on the 49a of the bar portion of hitting on this forearm 50, the piston 42 of total cylinder 36 is pushed upward, the elastic force pressure of these piston 42 opposing pull back springs 44 is moved upward along cylinder hole 41.Its result is to have dwindled the volume in the hydraulic pressure chamber 43, generation hydraulic pressure in this hydraulic pressure chamber 43.Then, this hydraulic pressure is delivered to the caliper body 35 of front-wheel brake Bf by hydraulic piping 37.So, the front-wheel brake Bf that is made of the fluid pressure type plate disc brake moves.
At this moment, as shown in figure 13, though leave retainer 55 because hit lever arm 49, still retainer 55 is applied the compressive load that is produced because of hysteresis spring 57, retainer 55 is afterburning by pushing downwards, so also keep original state.
Because if remove the operating effort of independent brake bar 3, then piston 42 is returned to initial lower position by the elastic force pressure of pull back spring 44, so front-wheel brake Bf becomes non-action status.
In addition, because if operations linkage brake rod 4, the interior wirerope 6a of the operation wirerope 6 of the brake-operating system B that then at first links is pulled, this tractive force does not add the throw rod 7r that is passed to rear wheel brake Br with changing, this throw rod 7r opposing pull back spring 8r rotates, so rear wheel brake Br action.Like this, at this moment, because the antagonistic force that on the outer wirerope 6b2 of outgoing side, produces as the trailing wheel brake operating wirerope 6 of the output wirerope of interlock brake-operating system B, and to supporting this outgoing side retainer 55 of wirerope 6b2 outward, apply and desire to make its (right among Fig. 9) mobile power upward.But, this power less than by hysteresis spring 57 during the mobile limiting force that retainer 55 applies, hit lever arm 49 and retainer 55 is maintained at original state.
If continue operations linkage brake rod 4 under this state, the antagonistic force that produces on the wirerope 6b2 outside the outgoing side of trailing wheel brake operating wirerope 6 further increases, and the power of then desiring retainer 55 is moved upward surpasses the mobile limiting force that is produced because of hysteresis spring 57.If so, then because retainer 55 is moved upward, this retainer 55 contacts with hitting lever arm 49 from the below, rotates to clockwise direction so this hits lever arm 49.Its result is that as shown in figure 14, by hitting the 49a of the bar portion of hitting of lever arm 49, the piston 42 of total cylinder 36 is brought to, and produces hydraulic pressure in the hydraulic pressure chamber 43 of this total cylinder 36.Therefore, identical during with operation independent brake bar 3, front-wheel brake Bf action.
Like this, when operations linkage brake rod 4, at first, rear wheel brake Br action, then, and through some time delays, the front-wheel brake Bf action that links.Because can simultaneously prevent the longitudinal vibration of vehicle in view of the above, one side can be roughly side by side to the front and back wheel braking, so can carry out the braking stably of two-wheeled motor vehicle.Then, because if remove the operating effort of interlock brake rod 4, then the throw rod 7r of rear wheel brake Br is returned to initial position by the elastic force pressure of pull back spring 8r, so rear wheel brake Br becomes non-action status.In addition, because the compressive load by hysteresis spring 57, retainer 55 moves downwards, accompanies therewith, hits lever arm 49 also to anticlockwise motion, so linkage 38 is returned to the state of Fig. 9.Have again, because the elastic force pressure of piston 42 by pull back spring 44 is returned to initial lower position, so front-wheel brake Bf also is a non-action status.
So, even any one party at front-wheel brake Bf and rear wheel brake Br is a hydraulic brake, the opposing party is under the situation of mechanical brake, also can be by the operation of interlock brake operating wirerope 5, make the hydraulic brake single movement, by the operation of interlock brake operating wirerope 6, make hydraulic brake and mechanical brake interlock action.
Above, be illustrated with regard to appropriate embodiment of the present invention, but the present invention only only limits to the foregoing description, can carry out various design modifications in the scope that does not break away from its purport.For example, the present invention also can be applied in motor-tricycle or the pony truck etc.
