Between above-mentioned support 94 and hole enlargement head 96a round fulcrum 96, be located between front wheel brake bar 31 and the support 94 for the pull back spring 106 of torsion spring, elastic force by means of pull back spring 106, front wheel brake bar 31 is given the direction of leaving grip part 89, even the power of the direction of press section 104 is left at junction surface 105, for the confined planes 107 of the rotation end that limits the front wheel brake bar 31 that rotates because of the effect of pull back spring 106 is located on the master cylinder 87 between two stands 94,95.Under the state that front wheel brake bar 31 and confined planes 107 join, the auxiliary operating lever 86 under the no external force active state is in by means of the elastic force of the spring 102 in the master cylinder 87 press section 104 is bonded on the position of reversing at junction surface 105.
Master cylinder 108 is installed on the master cylinder 87, and the test section 109 that can join with the detection head 108a of this halt switch 108 is arranged on the connecting portion 86b of auxiliary operating lever 86 integratedly.Be not subjected on the auxiliary operating lever 86 under the state of external force, by test section 109, under the state that is pressed into detection head 108a, be pressed under the piston rod 100a state corresponding to the rotation of auxiliary operating lever 86 and under having discharged state from above-mentioned test section 109 with press section 104 pressing force of detection head 108a, just can detect the non-action status and the operating state of auxiliary operating lever 86 with halt switch 108, i.e. front-wheel brake B
FNon-action status and operating state.
Together with reference to Figure 19 and Figure 20, an end is connected the other end of the front wheel brake rope 34 that is operating as on the feed rod 33 now, by may be controlled to only by front-wheel brake B when interlock brake rod 32 is operated
FProduce the gradual braking device 110 of braking force and be connected on the wrist 86c of auxiliary operating lever 86.
This gradual braking device 110 is provided with the cable folder 111 that is fixed tightly on the master cylinder 87, can be close, leave this cable and press from both sides cable adaptor union 112 on the wrist 86c that 111 ground are connected control lever 86, and be located between cable folder 111 and the cable adaptor union 112 and make cable adaptor union 112 towards leaving the limit spring 113 that cable presss from both sides 111 directions generation elastic force.
In the other end of front wheel brake rope 34, the thread barrel 118 of wearing external screw thread outward is fixed on the other end of outer cable 34a, and setting nut 119 is screwed onto on this thread barrel 118 with 120 of jam nuts.Make setting nut 119 and cable press from both sides 111 1 ends mutually ground connection thread barrel 118 is embedded in the mounting holes 115.And for example be provided with on the inner face of mounting hole 115 on the diameter line at this mounting hole 115 toward each other and along smooth face of joint 115a, 115a that axis direction extends, in the outside of thread barrel 118 smooth face of joint 118a, the 118a relative with these face of joints 115a, 115a be set.So, when thread barrel 118 embeds mounting holes 115, owing to face of joint 115a, 115a, 118a, 118a be bonded with each other stop thread barrel 118 in mounting hole 115 around rotational.
When the string that carries out front wheel brake rope 34 moves length adjustment, though change setting nut 119 and the advance and retreat position of jam nut 120 along thread barrel 118 axis directions, owing to stoped thread barrel 118 rotational in embedding mounting hole 115, so cable 34a is motionless outside needn't keeping when rotating setting nut 119 with jam nut 120, as long as rotate setting nut 119 and jam nut 120, so the moving length adjustment operation of the string of front wheel brake rope 34 is carried out easily.
On the other end of front wheel brake rope 34, pass cable folder 111 and stretch out to cable clamper 112 sides from the outstanding interior cable 34b of the other end of outer cable 34a, 123 joints of backing block that are located at the other end of rope 34b in this are attached on the end plate 112a of cable adaptor union 112.
And when front wheel brake bar 31 and interlock brake rod 32 are non-operating state, connecting pin 122 is in slotted hole 121 ... the end of opposition side of cable adaptor union 112 end plate 112a on, between the other end of cable adaptor union 112 end plate 112a and cable folder 111, then be set at the interval of regulation.
In such gradual braking device 110, at interlock brake rod 32 non-operating states, when promptly on front wheel brake rope 34, under the no tension state front wheel brake bar 31 being carried out brake operating, as shown in figure 21, to push press section 104 and pressing force acted on the piston rod 100a of master cylinder 87 in the junction surface 105 of front-wheel brake rod 31, can be at front-wheel brake B
FLast generation braking force, but at this moment, move connecting pin 122 just along slotted hole 121 corresponding to the revolution of auxiliary operating lever 86 ... move.So, no matter whether the elastic force of limit spring 113 acts on the cable adaptor union 112, the elastic force of this limit spring 113 all can not act on the front wheel brake bar 31, so identical effect obtains front-wheel brake B can be with the front wheel brake bar operation of the existing two-wheeled motorcycle that do not have link braking device the time
FBraking force.
At front wheel brake bar 31 is when carrying out the brake operating of interlock brake rod 32 under the non-operating state, by with the action of the corresponding operating effort feed rod 33 of the operation of this interlock brake rod 32, though also effect has brake operation force on front wheel brake rope 34, but before this brake operation force surpasses the setting load of limit spring 113, cable adaptor union 112 can not make its end plate 112a move to pressing from both sides on 111 directions near cable, thereby does not have the power effect from front wheel brake rope 34 on the auxiliary operating lever 86 yet.Promptly, at the brake operating initial stage of interlock brake rod 32, do not act on the master cylinder 87 with the corresponding power of setting load pressing force before affacting on the front wheel brake rope 34 of limit spring 113, thereby just suppressed front-wheel brake B at the operation initial stage of interlock brake rod 32 by operating effort feed rod 33
FThe performance of braking force.
When the power of the setting load that surpasses limit spring 113 when operating effort feed rod 33 affacts on the front wheel brake rope 34, because of the interior rope 34b tow adaptor union 112 of front wheel brake rope 34 makes its end plate 112a near cable folder 111, thereby auxiliary operating lever 86 is driven revolution and pushes piston rod 100a with its press section 104, so front-wheel brake B
FJust given play to braking force.
Then, as shown in Figure 22, when the end plate 112a of cable adaptor union 112 is connected on the other end of cable folder 111, even bigger brake operation force acts on the front wheel brake rope 34, because the action of cable adaptor union 112 is limited, then the action of auxiliary operating lever 86 also be limited, in other words, along with the operation of interlock brake rod 32, front-wheel brake B
FThe higher limit of the braking force that produces also is limited owing to the end plate 112a of cable adaptor union 112 and cable folder 111 join.
When handling interlock brake rod 32, handling front wheel brake bar 31, as shown in Figure 23, the action of cable adaptor union 112 is defined owing to its end plate 112a and cable folder 111 joins, because of connecting pin 122 can be along slotted hole 121 ... move, front wheel brake bar 31 is constantly pushed the press section 104 of auxiliary operating lever 86 with junction surface 105 and is turned, and what be accompanied by interlock brake rod 32 operates in front-wheel brake B
FThe middle generation is restricted to front-wheel brake B
FThe braking force of the higher limit of braking force, and in this wise, operating effort is inputed to the piston rod 100a of master cylinder 87.
When being attached to front wheel brake rope 34 on the auxiliary operating lever 86 by gradual braking device 110, owing to will constantly compress limit spring 113, the backing block 123 of interior rope 34b end is bonded on the end plate 112a of cable adaptor union 112, so make operation loaded down with trivial details.Therefore, as shown in Figure 24 and Figure 25, keep compressive state to make operation easy for making, at a pair of locating dowel pin 126,126 of another distolateral installation of cable folder 111 at assembling front limit spring 113.
For these locating dowel pins 126,126 are installed, be provided with two group every pair the hole 125,125 parallel in that another of cable 111 is distolateral with the one diameter; 125,125.Locating dowel pin 126 constitutes by inserting that linear in the mutual cooresponding hole 125,125 engages axial region 126a, the circular handle part 126b that links to each other with this joints axial region 126a one end and linking to each other with handle part 126b and press from both sides the waveform junction surface 126c that 111 periphery elasticity joins with cable, just can accept an end with joint axial region 126a, the 126a of two locating dowel pins 126,126 and be connected to the other end that one-tenth compressive state on the flange part 117 is housed in the limit spring 113 in the spring accepting hole 116.
At such installing and locating pin 126,126 limit spring 113 is become under the compressive state, backing block 123 on the interior rope 34b end of front wheel brake rope 34 joins with the end plate 112a of cable adaptor union 112, connecting the back extracts two locating dowel pins 126,126 from cable folder 111, limit spring 113 elongation becomes the state that the end plate 112a with cable adaptor union 112 joins, and just feasiblely by gradual braking device 110 operation that front wheel brake rope 34 is attached on the auxiliary operating lever 86 is carried out easily.
Below, the effect of this embodiment is described, when interlock brake rod 32 only carries out brake operating to front wheel brake bar 31 for serviceability not, use the auxiliary operating lever 86 that engages with front wheel brake bar 31 to make front-wheel brake B
FAlong with master cylinder 87 is pressed and moves, at front-wheel brake B
FThe middle braking force that produces.
When under not operating front wheel brake bar 31 states, interlock brake rod 32 being carried out brake operating, operating effort with this interlock brake rod 32 makes operating effort feed rod 33 move on to operating position, draws front wheel brake rope 34 and trailing wheel rope stopper 35 simultaneously by operating effort feed rod 33.At this moment, front wheel brake rope 34 is by being controlled to be when operating interlock brake rod 32 only by front-wheel brake B
FProduce the gradual braking device 110 of braking force and be connected and can pressing force be acted on the auxiliary operating lever 86 on the master cylinder 87, this gradual braking device 110 can suppress front-wheel brake B at the 32 brake operating initial stages of interlock brake rod
FBraking force performance, and be accompanied by the action of interlock brake rod 32, can be to front-wheel brake B
FThe braking force higher limit limit.And then, by means of interlock brake rod 32 at connection location on the operating effort feed rod 33 and front wheel brake rope distance L between the connection location on the operating effort feed rod 33
FSet the simple structure greater than interlock brake rod 32 distance L R between the connection location on the operating effort feed rod 33 at connection location on the operating effort feed rod 33 and trailing wheel rope stopper 35 for, the brake operation force that operating effort feed rod 33 is acted on the trailing wheel rope stopper 35 acts on brake operation force on the front wheel brake rope 34 greater than this bar.
So, just become as shown in Figure 26 with the corresponding brakig force distribution characteristic of the operation of interlock brake rod 32, have only the rear wheel-side braking force to produce the anterior sinkage of car at the operation initial stage of interlock brake rod 32, and the part that strengthens of the load of sharing by rider's loading compensation front-wheel, so can obtain the sensation of the anterior sinking of good brake car, can suitably control the anterior deflection of brake car at 32 operation initial stages of interlock brake rod.
From front-wheel brake B
FBegin to produce braking force and rise, make rear wheel brake B
RBraking force greater than front-wheel brake B
FBraking force, just can avoid with respect in the existing two-wheeled motorcycle that does not have a link braking device only when handling the trailing wheel brake rod and make the rear wheel brake action brake operating sense produce variation in the brake operating sense, so can enlarge the Applicable scope of link braking device to existing two-wheeled motorcycle.
And then, by the operation front-wheel brake B of restriction along with interlock brake rod 32
FThe higher limit of the braking force that produces can obtain rear wheel brake B when the 32 operation quantitative changes of interlock drg are big
RThe braking force of increasing, so can suppress front-wheel brake B
FBraking force and the anterior deflection of the brake car that obtains suiting.
Like this, owing to when operation interlock brake rod 32, control front-wheel brake B with gradual braking device 110
FThe braking force that is produced, the braking effect and the sensation that can keep 31 operations of front wheel brake bar to be produced, control front wheel brake power just can be improved and ride sensation to control the anterior deflection of suitable brake car.
Owing to make from the diameter of the operating effort feed rod 33 transmission front wheel brake rope 34 more less than above-mentioned brake operation force big than the diameter of the trailing wheel rope stopper 35 of big brake operation force, thereby the rigidity of the front wheel brake rope 34 that the rigidity that makes the big trailing wheel rope stopper 35 of drawing-in motion amount is more less than drawing-in motion amount is big, just can make the stroke of two rope stoppers 34,35 be adapted to its traction and draw actuating quantity, and make the actuating quantity of operating effort feed rod 33 suitable.
When braking force holder 70 actions, rotating operation bar 72 under operation interlock brake rod 32 states.So, just as shown in Figure 12, braking force keeping arm 71 resists the elastic force of pull back springs 73 and shifts to engage position from unengaged position, and the double pointed nail 77 of braking force keeping arm 71 just is bonded on the retainer 79,79 of the operating effort feed rod 33 that moves to operating position.In case the operating effort of interlock brake rod 32 is removed, operating effort feed rod 33 becomes trailing wheel rope stopper 35 for drawing-in motion state front wheel brake rope 34 then is the braking force holding position of non-traction state with regard to action, just becomes just rear wheel brake B under this state
RMove and front-wheel brake B
FThe state of being failure to actuate, such braking force hold mode is detected by halt switch 68.Promptly when braking force keeps, as fluid pressure type front-wheel brake B
FRubber Parts such as the pipeline of component parts and sealing member are not subjected to hydraulic action, so be expected to increase the life-span of rubber components.
The rope stopper that above-mentioned retainer 79,79 is arranged in front wheel brake rope 34 and the trailing wheel rope stopper 35 on the operating effort feed rod 33 from the less side of connecting part distance of interlock brake rod 33 is trailing wheel rope stopper 35 1 sides, 77 of the double pointed nails of braking force holder 70 are bonded on the operating effort feed rod 33 corresponding to the bigger side of interlock brake rod 32 operational motions, so the operational ton of the interlock brake rod 32 can make braking force holder 70 actions the time is less.
In order to remove this braking force hold mode, as long as rotate interlock brake rod 32, so, braking force keeping arm 71 just moves to unengaged position from engage position and has just removed the engagement state of braking force holder 71 with operating effort feed rod 33 under the elastic force effect of pull back spring 73, because interlock brake rod 32 restores, operating effort feed rod 33 returns non-operating position, rear wheel brake B
RJust become dormant state.
