This left tooth bar 20 and right tooth bar 30 all can be arranged in shell 10 the most actively, this front brake slide block 40, moving gear 50 and rear brake slide block 60 are respectively positioned in shell 10, in the present embodiment, described shell 10 includes pedestal 11 and lid 12, this pedestal 11 is connected by screw 13 is fixing with lid 12, pedestal 11 and lid 12 enclose and are configured to accommodation space, this left tooth bar 20, right tooth bar 30, front brake slide block 40, moving gear 50 and rear brake slide block 60 are all accommodated in accommodation space, and, it is folded with sealing gasket 14 between described pedestal 11 and lid 12, to avoid the impurity such as water to enter in shell 10.
This moving gear 50 is braked on slide block 40 before being rotatably installed on, this moving gear 50 and left tooth bar 20, right tooth bar 30 are ratcheting, moving gear 50 is driven by left tooth bar 20 or right tooth bar 30, in the present embodiment, before described, brake slide block 40 is U-shaped, having a storage tank 41 on front brake slide block 40, this moving gear 50 is rotatably installed in storage tank 41 by an axle center 81.
This rear brake slide block 60 is movable with left tooth bar 20 or right tooth bar 30, this left brake wire 71 and right brake wire 72 fix the one end being connected and stretching out shell 10 respectively with left tooth bar 20 and right tooth bar 30, and this front brake wire 73 and rear brake wire 74 fix the other end being connected and stretching out shell 10 respectively with front brake slide block 40 and rear brake slide block 60.In the present embodiment, the two ends of described rear brake slide block 60 are butted on left tooth bar 20 and right tooth bar 30 respectively, and the two ends of this rear brake slide block 60 arrange and are provided with through hole 61, and this left brake wire 71 and right brake wire 72 are each passed through the through hole 61 of correspondence；Further, described left brake wire 71 and right brake wire 72 are fixedly clamped on left tooth bar 20 and right tooth bar 30 by left clamping block 82 and right clamping block 83 respectively, and this left clamping block 82 and right clamping block 83 are all fixed on left tooth bar 20 and right tooth bar 30 by screw 84.
And, it being arranged with the first spring 85 outside described left brake wire 71, the two ends of this first spring 85 are butted between the inwall of shell 10 and left tooth bar 20 respectively.Being arranged with the second spring 86 outside described right brake wire 72, the two ends of this second spring 86 are butted between the inwall of shell 10 and right tooth bar 30 respectively.
During installation, generally this this product first can be fixed on leading front bar or the cross bar of vehicle, then left brake wire 71 and right brake wire 72 are each passed through left tooth bar 20 and right tooth bar 30, re-use left clamping block 82 and right clamping block 83 screw 84 left brake wire 71 and right brake wire 72 to be fixed on left tooth bar 20 and right tooth bar 30, the most front brake wire 73 is passed the hole of front brake slide block 40, then rear brake wire 74 is passed the hole of rear brake slide block 60, finally above each part is put in shell 10, then left brake wire 71 is allowed, right brake wire 72, front brake wire 73 and rear brake wire 74 outwards wear out from shell 10 is inner, i.e. installation.
During use, the most left brake wire 71 can pull left tooth bar 20 to slide up and down in shell 10；Right brake wire 72 can draw right tooth bar 30 to slide up and down in shell 10.
Specifically, when one hand is braked, such as when left hand is first braked, left brake wire 71 moves the most at once, drives left tooth bar 20 to move；When left tooth bar 20 moves, the slide block 60 movement with moving gear 50 of braking after simultaneously driving；The movement of brake wire 74 after then brake slide block 60 drives the most at once, and its to move degree identical with left brake wire 71；But it is motionless to be because right tooth bar 30, therefore the displacement of moving gear 50 is only the half of left tooth bar 20, so moving gear 50 is braked before driving, before slide block 40, then drive, the movement degree of brake wire 73 is just the half of left brake wire 71.This most so-called nonsynchronous displacement mode of homophase.
After the left hand of knight is first braked and maintained static, then when braking with the right hand, right brake wire 72 moves the most at once, drives right tooth bar 30 to move, and drives the movement of moving gear 50 simultaneously；Because the most left tooth bar 20 is motionless, therefore the displacement of moving gear 50 is only the half of right tooth bar 30, so moving gear 50 is braked before driving, before slide block 40, then drive, the movement degree of brake wire 73 is just the half of right brake wire 72.But because rear brake slide block 60 is moved into departing from the position of right tooth bar 30 contact, so right tooth bar 30 is now and the movement of slide block 60 of cannot braking after driving, so now brake wire 74 no longer moving afterwards.
Noted earlier is the operational circumstances first using left hand brake to re-use right hand brake, and the result in fact making into first to use right hand brake to re-use left hand brake is also identical.
If make to brake the most simultaneously, when right-hand man's displacement difference, the most left brake wire 71 displacement 1 centimeter, right brake wire 72 displacement 0.5 centimeter, because the effect that left brake wire 71 and right brake wire 72 have to pass through moving gear 50 could drive front brake wire 73, so brake wire 73 replacement course degree is (1+0.5)/2 centimeter before in theory, i.e. equal to 0.75 centimeter；But because left brake wire 71 or right brake wire 72 can after left tooth bar 20 or right tooth bar 30 directly drive brake wire 74, after, the displacement of brake wire 74 is max (1,0.5) centimetre, namely in the brake wire of left and right, after the decision of displacement the greater, the degree of displacement of brake wire 74, is 1 centimeter in this instance.
In fact can be learnt by embodiment above, this braking system can provide a kind of brake result, the degree of displacement being exactly rear brake wire 74 is identical with displacement the greater in left brake wire 71 or right brake wire 72, the displacement of front brake wire 73 is then the meansigma methods of left brake wire 71 and right brake wire 72 degree of displacement, after, the degree of displacement of brake wire 74 is necessarily greater than or equal to front brake wire 73, so can reach target of the present utility model.
Additionally, after knight pulls left brake wire 71 or right brake wire 72 to decontrol again, theoretical upper left tooth bar 20 or right tooth bar 30 should return in situ, in order to the carrying out braked next time, but due to the relation of system friction, left tooth bar 20 or right tooth bar 30 may not necessarily playback smoothly, it is provided by the first spring 85 and the second spring 86, allow left tooth bar 20 or right tooth bar 30 after a procedure, can playback immediately because of the elastic force of spring.
When the most excessive knight pulls left brake wire 71 with right brake wire 72 simultaneously, and right-hand man's displacement identical time, the most left brake wire 71, right brake wire 72, front brake wire 73 is the most identical with rear brake wire 74 degree of displacement, now it is possible to brake deadlock before allowing car allow before deceleration and the danger overturned, so the second spring 86 is placed between right tooth bar 30 and shell 10, the right hand is allowed when braking, to produce extra resistance, slow down the translational speed of right tooth bar 30, even if so both hands are braked simultaneously, also the time difference that left tooth bar 20 moves can be produced with right tooth bar 30, thus the risk reducing front brake deadlock and overturning.Or, one first spring 85 is placed between left tooth bar 20 and shell 10, left hand is allowed when braking, to produce extra resistance, slow down the translational speed of left tooth bar 20, even if so both hands are braked simultaneously, also the time difference that left tooth bar 20 moves can be produced with right tooth bar 30, thus brake deadlock and the risk overturned before reducing.Or use the first spring 85 and the second spring 86 of different coefficient of elasticity, it is respectively placed between left tooth bar 20 and shell 10, and between right tooth bar 30 and shell 10, allow a wherein handbrake time produce extra resistance, even if so both hands are braked simultaneously, also the time difference that left tooth bar 20 moves can be produced with right tooth bar 30, thus brake deadlock and the risk overturned before reducing.
Design focal point of the present utility model is: no matter use left hand or the right hand first to brake, if singlehanded brake, this product is all provided that the brake of sufficient trailing wheel and the effect of part front-wheel brake, if after singlehanded brake, when adding another handbrake, this device just can reoffer more front-wheel brake effect, the most i.e. can reach the purpose that the most very trailing wheel brakes front wheel again in trailing wheel is fully braked.If two handss are braked simultaneously, this brake device still can provide first very trailing wheel to brake front wheel or the effect of the most very front and back wheel again.If making into this braking system, with both feet manipulation, also can reach, with the effect wanted, effectively to stop to occur overturning phenomenon because of brake, security performance gets a promotion significantly.
The above, it it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, therefore every any trickle amendment, equivalent variations and modification above example made according to technical spirit of the present utility model, all still fall within the range of technical solutions of the utility model.
