The specific embodiment
The disclosed this Parking Brake of the present invention is an electromechanical integrated product, is applicable to the braking of open form self-propelled vehicle.
Referring to accompanying drawing 1, this open form self-propelled vehicle Parking Brake, the servo-actuated pedal gear of comprise pulse switch mechanism, combining and shifting fork mechanism, magnetic control detent mechanism.
A, pulse switch mechanism comprise the 24 in-to-in extension springs 26 of pulse switch key lever 19 and switch case, swing arm, key and line bank 25.The end of swing arm and key is provided with the contact, i.e. swing arm contact 28 and key contact 29, and the other end of key is connected through key axle 30 with switch key lever 19.Swing arm comprises that wherein an end of a monomer is connected with extension spring 26 with swing arm rotating shaft 27 pivotallys attached two joint monomers formations, and the other end of another monomer is provided with swing arm contact 28, and the swing arm tip side can rotate around swing arm rotating shaft 27.This swing arm contact 28 and key contact 29 corresponding settings.The lower surface of the end of key is that key contact 29, upper surface are insulator 23.Switch closure when key contact 29 contacts with swing arm contact 28 produces pulse.
Its principle of work: referring to accompanying drawing 2, when switch key lever 19 is upwards stirred in the direction of arrows, key contact 29 contacts with swing arm contact 28; This moment switch closure, switch key lever 19 is rotated further and reaches the desired location, two contacts are separated; Original position is got back in swing arm contact 28 under the effect of extension spring 26, switch breaks off; Because 19 actions of switch key lever are very fast, so the closing period of switch is very short, so be called pulse switch.When switch key lever 19 returns,,, then do not produce pulse because the key contact upper end is an insulator 23 though key contact 29 contacts with rocking arm contact 28.
B, servo-actuated pedal gear comprise braking during standstill pedal 1 and pedal-rod 2, and the top of pedal-rod 2 is sleeved on the ratchet shaft 7, and the two is hinged, and the torque spring 6 that is sleeved on the ratchet shaft 7 is connected with spring detent 4 with ratchet pin 8 respectively.Torque spring 6 one ends and spring detent 4 sockets, the other end and ratchet pin 8 closely touch.The upper end of pedal-rod 2 is the shift fork 3 of band groove, and the switch key lever 19 of pulse switch mechanism is inserted in the groove of shift fork 3.Shifting fork mechanism is the mode of stepping transmission, and in ratchet shaft 7 rotating process, shift fork is with the mode of intermittently-driving at pedal-rod 2, successively toggle switch key lever 19 and ratchet pin 8.The end of Parking bar position plus-minus screw 5 contacts with pedal-rod 2, can adjust its initial position, plays position-limiting action.
C, magnetic control detent mechanism comprise electromagnet 17 and ratchet 10, and electromagnet 17 is connected with ratchet 10 1 ends through the pull bar 22 that is set with thrust spring 21, and the end of ratchet 10 and mode switch 16 touch, and the other end apical grafting of ratchet 10 is on the gear teeth of ratchet 9.
One end clamping of the top of d, said ratchet 9 and brake cable 12, this brake cable 12 change brake efficiency through fixed support 15 fastening being installed on the base plate 20 through brake cable plus-minus screw 14.The upper end of ratchet is provided with brake cable draw-in groove 11, and an end of brake cable 12 is installed in this draw-in groove.The other end of brake cable 12 is connected with self-propelled vehicle braking shoes pull bar.
The principle of work of magnetic control detent mechanism is: shown in accompanying drawing 4-5; State shown in the figure is the state before the Parking, when Parking, firmly tramples braking during standstill pedal 1; Pedal-rod 2 is clockwise rotated around ratchet shaft 7; At this moment the shift fork 3 of pedal-rod 2 upper ends is at first upwards stirred the switch key lever 19 of pulse switch, makes the instantaneous closure of switch; Shift fork 3 on the pedal-rod 2 has a segment distance so belong to the intermittently-driving design with ratchet pin 8, and after pulse switch key lever 19 put in place, shift fork 3 began again to stir ratchet pin 8, and ratchet 9 is rotated.Ratchet 9 upper ends connect Parking cable wire 12, and under the effect of torque spring and ratchet pin, ratchet is under the effect of shift fork moment, and corner increases thereupon, and Parking moment will increase thereupon.
The initial position of the ratchet gear teeth is provided with groove, so before the Parking, the front end of ratchet 10 is inserted within the groove, and ratchet 10 can be around pawl axis 13 swings.Ratchet 9 clockwise rotates under the effect of treadle shift fork gradually; Make ratchet move up along the ratchet recesses slope, the other end of ratchet is connected with the pull bar 22 of electromagnet 17, and pull bar 22 is under the promotion of electromagnet thrust spring 21; Ratchet locks ratchet constantly, and ratchet can not be turned round.Unclamp the Parking pedal, cable wire still keeps tension, realizes Parking.
E, electromagnet are connected with self-propelled vehicle key switch, silicon control, mode switch and pulse switch respectively, constitute electronic circuit, also comprise links such as indicator lamp, flywheel diode, line bank in this electronic circuit.This electromagnetism circuit is through the action of electromagnetic control ratchet.In implementing the process of Parking, the action of ratchet makes that mode switch 16 changes in the circuit, and mode switch is closed, and the A point transfers high level to by low level, and the Parking indicator lamp is bright to be opened.Fig. 1, Fig. 4 and Fig. 5 are three kinds of states of Parking Brake.
When needs are removed braking during standstill, only need jam on the Parking pedal once more, at this moment shift fork makes pulse switch 18 closures again; The level signal of pulse switch 18 and the level signal of mode switch constitute logical relation at this moment, make the silicon control triggering and conducting; Electromagnet gets electric, spurs ratchet downwards, and ratchet is removed the constraint to ratchet; Along with reducing of Parking pedal pressing force, ratchet conter clockwise under the effect of brake cable turns to initial position, realizes removing braking during standstill.Because brake off is to lean on electromagnet tractive ratchet to accomplish, so after key switch was closed, the car load outage can't be removed braking during standstill.So the present invention really plays the purpose of safe Parking to the open form motor vehicle energy.
Shown in accompanying drawing 3, circuit working principle of the present invention: key switch (K1) closure, when Parking; The Parking pedal is stressed, and shift fork begins to rotate, and (K3) moment is closed; Although (K3) move, do not have pulse to produce owing to (A) still be in low level this moment.After Parking realized, mode switch (K2) closed (A) point was high level, LED light (D1) conducting, expression Parking state; When removing braking during standstill, (A) be in high level, the Parking pedal is stressed once more, and shift fork rotates once more; (K3) moment closed, produce impulse singla and trigger silicon control (CTR) conducting through resistance (R2), electromagnet gets; Produce magnetic force through pull bar traction ratchet, discharge ratchet, ratchet is got back to initial position; Braking during standstill is removed, and mode switch (K2) breaks off, and silicon control turn-offs; Induced current in the electromagnet discharges through flywheel diode (D2), indicates that simultaneously the LED light of Parking state is ended.The working current of electromagnet is that the 1A break-make is realized by silicon control, therefore (K2), (K3) switch, and in the process of switching, the about 5mA of electric current, the discharge off spark, circuit safety is reliable.
