1, the working process of first kind of embodiment of the present invention is such:
(1), implement braking:
Begin to implement glancing impact to vehicle, it is close that the rest position of manipulatable end brake off state below it of joystick is up pulled to its regional location of implementing braking mode, beginning under the situation also little to the manipulation application force of vehicle enforcement braking, the control stalk 5.5 that locks mechanism opening is handled in increasing with the manipulation application force of linking to each other with braking input manipulating pulling cable core 3.1, under the effect of conversion transmission speed force-limit spring 5.9 and secondary conversion transmission speed force-limit spring 5.91, cause it to abut against on second stop gear 5.4, allow and increase the manipulating pulling cable 5.6 maintenance relaxed state of handling the locking mechanism opening with application force, thereby the first lockout mechanism tooth bar 6.4 that transference fulcrum setting transmission speed adjust bar 5 at one end links to each other, first lockout mechanism that constitutes with being arranged on the first lockout mechanism dead bolt 6.5 on the bar 6.1 that drives up, can under the application force of very little return elastic force, can keep lock-out state, so that can drive the effect of bar 6.1 of driving up that fulcrum is arranged on the middle part by the connecting rod 6.2 that drives up, driving mobile manipulating pulling cable overcoat limits the direction that the very fast usable length to causing the total drag-line overcoat of braking of mechanism 6.3 increases (just very fast to the direction that helps to the braking of car brakeing mechanism for implementing) and changes, when the summation length of usable length AB+BC+CD of the total drag-line overcoat of braking rises to one regularly, the pulling force of braking input manipulating pulling cable core 3.1 will increase gradually, pulling force when braking input manipulating pulling cable core 3.1, increase to greater than after the closing of the application force of force-limit spring 5.9 and secondary force-limit spring 5.91, link to each other with braking input manipulating pulling cable core 3.1 with handle application force increase handle the control stalk 5.5 that locks mechanism opening will be close to first stop gear 5.3, increasing the control stalk 5.5 of handling the locking mechanism opening in the middle of the close process of first stop gear 5.3 to handle application force, it also can be by increasing the transmission of the manipulating pulling cable 5.6 of handling the locking mechanism opening with application force, the first lockout mechanism dead bolt 6.5 and the first lockout mechanism tooth bar 6.4 are separated, cause first lockout mechanism to be opened, after first lockout mechanism is opened, joystick is by the transmission of braking input manipulating pulling cable core 3.1, force E point in the stop mechanism 6 of transmission speed adjust bar 5 powered vehicle to the stroke of the close enforcement of D point brake action, just can only through with transmission speed adjust bar 5 on a retaining place of being in transmission connection 4.7 or the two retaining brakings that link to each other of the places of being in transmission connection 4.8 export manipulating pulling cable core 4.1 and carried out transmission at a slow speed, after the working tension of giving braking input manipulating pulling cable core 3.1 increases to certain value, increasing the control stalk 5.5 of handling the locking mechanism opening with the manipulation application force will abut against on first stop gear 5.3, can not allow the first lockout mechanism dead bolt 6.5 continue to have moved again to the direction that increases its gap, at this moment to implement braking during standstill to vehicle in this way, as long as joystick is up drawn again just passable.(the above-mentioned vehicle of giving is when coming into effect braking, be arranged on brake off institute energy requirement on the transmission speed adjust bar 5 produce mechanism 1 with, store under the effect of the energy requirement generation mechanism 2 9.2 of brake off institute that locking tooth bar 7 links to each other with brake off institute energy requirement, force the energy-storaging spring 8 of brake off institute energy requirement to produce the required energy of brake off, and store the locking action that lockout mechanism and brake off institute energy requirement discharge lockout mechanism by brake off institute energy requirement, store after this implementing the required energy of thorough brake off.When the energy-storaging spring 8 that forces brake off institute energy requirement produces the required energy of brake off, locking tooth bar 7 can drive the control of brake off institute energy requirement release control push rod again and shoulder bar 7.9, discharge the effect of the control stalk 7.8 of control push rod by brake off institute energy requirement, cause brake off institute energy requirement to discharge control push rod 7.7 and aim at transmission speed adjust bar 5, when after this being returned to the brake off seat in order to transmission speed adjust bar 5, brake off institute energy requirement is discharged lockout mechanism to be opened to implement thorough brake off, that is to say that working as transmission speed adjust bar 5 one leaves the brake off position, brake off institute energy requirement discharges control push rod 7.7 will aim at transmission speed adjust bar 5 in order to implementing thorough brake off, when mobile manipulating pulling cable overcoat limits mechanism 6.3 to thorough brake off state position, when the energy-storaging spring 8 that is to say brake off institute energy requirement has not stored energy, brake off institute energy requirement discharges control push rod 7.7 can not aim at transmission speed adjust bar 5, keeps lock-out state so that allow brake off institute energy requirement discharge lockout mechanism.)
At this moment to implement emergency brake to vehicle in this way, will subdue the ammonium button on joystick top (in order to avoid wheel and road surface are when beginning to skid, again a bit) and then with joystick up draw the downward pine of joystick, when wheel and road surface begin to skid, with the downward pine of the manipulatable end of joystick a bit, when wheel began to rotate again, the manipulatable end with joystick upwards drew a bit again, repetitive operation for several times can be until stopping also soon its being braked at the vehicle of running at high speed like this.
Cross for a long time not adjustment and maintenance as vehicle braked mechanism, after upwards having moved the manipulatable end of joystick to stop, also not car brakeing under the plot good or that also the car brakeing of also travelling is not again lived, can be with the manipulatable end of joystick again to the stop position return certain distance of its brake off state, if return has not soon just down pushed away behind stop again, so can not cause and separate fully in the effect stroke that will last time implement braking and not remove (in the middle of process the manipulatable end return of joystick to vehicle, first lockout mechanism and second lockout mechanism are under the effect of return elastic force, and they all still keep lock-out state.Therefore at this moment mobile manipulating pulling cable overcoat limits mechanism 6.3 under the application force of pull back spring, still can not be to impairing the direction return of implementing braking to vehicle, and the transmission speed adjust bar 5 that at this moment links to each other with braking input manipulating pulling cable core 3.1, and first lockout mechanism tooth bar 6.4 under the effect of retracing spring, be will to can increase this device give next time car brakeing mechanism for implementing brake action the effect stroke direction and move, so lockout mechanism does not play locking action to them, because the manipulatable end with joystick is not returned to stop, transmission speed adjust bar 5 does not also force brake off institute energy requirement to discharge control push rod 7.7 with return elastic force and shoulders bar 7.6 through the energy requirement release control of brake off institute, brake off institute energy requirement is discharged lockout mechanism to be opened, so this device was not also last time separated joystick fully to the effect stroke of vehicle enforcement brake action and was removed), and then the manipulatable end of joystick up drawn again, in the middle of the process that the manipulatable end that begins once more joystick up draws, when beginning is up drawn the manipulatable end of joystick again, because it is at this moment also little to the application force of vehicle enforcement braking, first lockout mechanism and second lockout mechanism are under the effect of return elastic force, and they all still keep lock-out state.Again as above-mentioned said, it also can continue to increase with very fast speed the usable length of brake cable pull overcoat (AB+BC+CD), continue at high speed with this and increase the effect stroke that this device is given vehicle braked mechanism for implementing brake action, after up having moved the manipulatable end of joystick to stop once more, also not under the good plot of car brakeing, also can be again as above-mentioned said, repeat function once or again repeat function for several times can be till live by or braking good car brakeing again.
(2), brake off: the manipulatable end with joystick is pulled upwardly a little earlier, depress the control ammonium button on joystick top again, manipulatable end with joystick down pushes away then, braking just has been disengaged substantially when transmission speed adjust bar 5 and brake off institute energy requirement discharge control push rod 7.7 and begin to contact, transmission speed adjust bar 5 is under the application force of pull back spring after down pushing away a bit again, promotion brake off institute energy requirement release control push rod 7.7 is shouldered bar 7.6 by the energy requirement release control of brake off institute forces brake off institute energy requirement release lockout mechanism to be opened, allow the energy-storaging spring 8 of brake off institute energy requirement release energy, force first lockout mechanism and second lockout mechanism to be opened entirely by locking mechanism controls first manipulating pulling cable 3.5 and locking mechanism controls second manipulating pulling cable 3.6, allow mobile manipulating pulling cable overcoat limit mechanism 6.3 under the effect of retracing spring, to the direction motion of shortening braking total drag-line overcoat (AB+BC+CD) usable length, allow vehicle braked mechanism continue to be returned to the position of its thorough brake off state, thereby allow vehicle ' freely.
During above-mentioned enforcement brake off, mobile manipulating pulling cable overcoat limits mechanism 6.3 when thoroughly getting back to the position, it will drive brake off institute energy requirement locking mechanism controls push rod 7.3 and shoulder bar 7.2 by the locking mechanism controls of brake off institute energy requirement, brake off institute energy requirement is stored lockout mechanism to be opened, allow brake off institute energy requirement energy-storaging spring 8 keep fully not energy accumulating state, like this under the application force of locking mechanism controls first manipulating pulling cable 3.5 and locking mechanism controls second manipulating pulling cable 3.6 pull back springs, allow first lockout mechanism and second lockout mechanism under the state of complete brake off, all keep lock-out state again, so that next time is standby to vehicle enforcement glancing impact institute, the locking tooth bar 7 that stores when brake off institute energy requirement, when under the application force of locking mechanism controls first manipulating pulling cable 3.5 and locking mechanism controls second manipulating pulling cable 3.6 pull back springs, getting back to, the locking tooth bar 7 that brake off institute energy requirement stores will drive the control of brake off institute energy requirement release control push rod and shoulder bar 7.9, the control stalk 7.8 that discharges the control push rod by brake off institute energy requirement discharges control push rod 7.7 with brake off institute energy requirement and staggers with transmission speed adjust bar 5, and cause brake off institute energy requirement to discharge lockout mechanism, under the application force of pull back spring, keep lock-out state, so that begin to implement glancing impact to vehicle in next time, when just the energy-storaging spring 8 of brake off institute energy requirement comes into effect accumulation of energy, can be as for first lockout mechanism and second lockout mechanism are manipulated to open mode.
The working process of first kind of embodiment of the working process of second kind of embodiment of the present invention and the present invention is the same substantially, nothing but the locking tooth bar 7 that brake off institute energy requirement is stored, change over the lock gear 7.0 of brake off institute energy requirement, brake the output manipulating pulling cable for one group that constitutes by braking output manipulating pulling cable core 4.1 and braking output manipulating pulling cable overcoat 4.2, change over by braking output manipulating pulling cable core 4.1 and braking output manipulating pulling cable overcoat 4.2 and manipulating pulling cable is exported in one group of braking that the braking output manipulating pulling cable 4 that constitutes constitutes with the second brake operation drag-line 4.3.
As change the parking brake lever and the support bracket fastened structure of joystick of existing vehicle, as notification number 200610173368.3 employed devices, the holding brake device that to be exactly this device combine mutually with the parking brake lever of vehicle, as long as it is just passable that this sample device just is provided with two lockout mechanisms, as brake off institute energy requirement energy-storaging spring is not set, its manipulating pulling cable is just passable with regard to only being provided with two groups with the sample device.
