Shown in Figure 4 is that drg of the present invention arrives the braking distance h that latched position produced from initial position.
Working of brakes principle of the present invention is as follows:
Fig. 5～Fig. 8 is a working of brakes principle schematic of the present invention, its action is that circulation occurs, promptly, from Fig. 5, after Fig. 6, Fig. 7, Fig. 8, come back to Fig. 5 (because the composition relation, retracing spring 3 shown in Figure 1 is omitted and does not draw, but the reset function of this spring is not omitted) in this figure.
What Fig. 5 showed is the preceding initial condition of braking during standstill, and what the direction of action arrow of each part that marks among the figure was expressed is the direction of action of part before mechanism resets to this initial condition; This moment, pedal was in a high position, and control screw 7 and elastic dialing remain in the gap between referring to 5, thereby control lever 6 is in free state.At this moment, elastic dialing refers to that 5 stylus pin 501 withstands lock pawl 4 upper edges by lock pawl point 401 1 sides, lock pawl 4 is pressed onto the end position of left-hand revolution, 401 of lock pawl points have reached steps on arm latch hook 102 below the arc track S that steps on 201 rotations of arm pivot, because lock pawl locating dowel pin 402 is subjected to lock pawl position-limited trough 206 restriction topmost, lock pawl 4 can't continue rotation.As a same reason, elastic dialing refers to 5 end positions that are limited in clickwise.
What Fig. 6 showed is in the braking procedure of push down on the pedal, steps on arm 1 around stepping on the position that 201 rotations of arm pivot arrive.At this moment, step on arm latch hook 102 tops lock pawl point 401 is boosted the equitant critical conditions with latch hook top path of motion S.At as shown in Figure 5 initial condition in this section braking procedure of current state development, step on lever thrust face 103 on the arm 1 around stepping on arm pivot 201 clickwises, promoting control lever 6 swings, after the gap of initial state is eliminated, control screw 7 promotes elastic dialing and refers to that 5 produce left-hand revolution, stylus pin 501 pressurizeds retraction, the origin of force between stylus pin 501 and the lock pawl 4 is positioned at the left side in lock pawl pivot 202 axle center.
Fig. 7 is first control position of braking during standstill, before stepping on arm and crossing the figure position continue descending, the attitude when lock pawl has entered latched position, at this moment, braking during standstill is realized; Cross position shown in Figure 6 and continue when descending when stepping on arm 1, lock pawl point 401 disengages with the top of stepping on arm latch hook 102, because the force direction of stylus pin 501 still is positioned at the left side in lock pawl pivot 202 axle center and enough offset X is arranged, elastic dialing refers to that the spring in 5 ejects stylus pin 501, compressing lock pawl 4 quick left-hand revolutions, elastic dialing refers to that 5 also slide and quick clickwise owing to stylus pin 501 left simultaneously, like this, lock pawl point 401 is pressed towards the hook trench bottom of stepping on arm latch hook 102 and enters latched position.When lock pawl locating dowel pin 402 swung to end position and lock pawl position-limited trough 206 ends generation bump fast, clear and melodious " clatter " sound spread out of, and had formed notifying operation person Parking and had locked the sound signal of realizing, can finish trample action.In the process from Fig. 5 to Fig. 7, the position of backguy axle 101 has produced lifting capacity h (see figure 4), this lifting capacity is by the transmission of driven part drag-line suspension member 9, hanging scroll 10, adjusting bolt 11 and drag-line balance element 12, and to braking mode, braking during standstill is so far realized with cable pull.At this moment, the operator can remove safety from pedal with application of force pin and leave away, because lock pawl 4 and step on 102 stable occluding relations of arm latch hook, stepping on that arm 1 is locked can't resilience, and the braking during standstill state is maintained constant.
Fig. 8 is second control position of braking during standstill, i.e. the terminal point of the release stroke that arrives of push down on the pedal again.In the appropriate location of release stroke, lock pawl is activated by mechanism action, forms the lock pawl point and is lifted to the released state of stepping on more than the running orbit of arm latch hook top, and loosening pedal this moment can be so that it gets back to the preceding initial position shown in Figure 5 of braking beginning smoothly.Under the lock-out state of first control position shown in Figure 7, step on once more and step on arm 1 and make in its stroke that reaches this figure release state, the cw swing takes place in lever thrust face 103 once more, control screw 7 promotes elastic dialing and refers to 5 left-hand revolutions, stylus pin 501 progressively bounces back thereupon, when stylus pin 501 and 4 lines of action of force of lock pawl are transferred to the right side from the left side of lock pawl pivot 202, when departure distance reaches X1, the clockwise rotating torque that 501 pairs of lock pawls 4 of stylus pin apply has overcome the friction drag between lock pawl pivot 202 and lock pawl pivot hole, cause lock pawl 4 that clickwise takes place, elastic dialing refers to that the pressure of 5 inner springs is with stylus pin 501 releases, rapidly lock pawl 4 is pressed onto the cw end position, this moment, lock pawl locating dowel pin 402 was limited by the lower end of lock pawl position-limited trough 206 on the support 2,401 of lock pawl points are lifted on the running orbit S that steps on arm latch hook 102, no longer the motion of stepping on arm latch hook 102 are exerted an influence.
Device is as follows from the process that Fig. 8 gets back to Fig. 5, under Fig. 8 state, unclamp pedal, step on arm 1 under the restoring force effect of retracing spring 3, that will have no to hinder returns to initial position shown in Figure 5 in the counterclockwise direction, in this process, being fixed in the lower end of stepping on the arm 1 that dial to refer to return unit 104 stirs elastic dialing and refers to 5, its position cw of expressing from Fig. 8 solid line dialled forward the expressed position of Fig. 5 dotted line to, at this moment, because the left side of lock pawl pivot 202 is got back in the sensing of stylus pin 501 and 4 application forces of lock pawl deflection again, eccentric throw is the X2 (see figure 5), so left-hand revolution takes place again in lock pawl 4, thereby get back to state shown in Figure 5, stylus pin 501 is owing to the left-hand revolution of lock pawl 4 continues to slide and ejection to lock pawl point 401 1 sides, drive elastic dialing and refer to that 5 are rotated clockwise to group finger position-limited trough 205 spacing positions (solid line position among Fig. 5), control lever 6 is also push-jump by conter clockwise, gets back under the free state shown in Figure 5.
The method of adjustment of release stroke is as follows: will control screw 7 suitably screw in end distances from, can impel the release action to take place in advance, that is shorten the release stroke; Otherwise will control screw and suitably screw out a segment distance, and then can postpone the generation of release action, that is strengthen the release stroke.After ideal position is adjusted in the position of control screw 7, jam nut 8 should be tightened on the plane of cooresponding with it control lever 6, like this, the position of control screw 7 is fixed, and the release stroke of having adjusted just can not change yet again.
Fig. 9 is the pedal brake force curve, shown the possible distribution limit of braking force when prior art ratchet-ratchet Parking lockout mechanism locks, wherein Nbmin represents to satisfy the required braking force of Parking on the ramp of vehicle technology condition regulation, Nmax and Nmin are the upper and lower boundaries on brake application curve (Nmax is applicable to that ramp, Nmin are applicable to the level land) that ratchet-practical operation of ratchet Parking lockout mechanism may reach, and Lbmin, Lmax and Lmin then are with the corresponding braking distance of footnote braking force with above-mentioned.From this figure as can be seen, because the influence of certain factor (as operator's muscle power, mood or attention change etc.), the braking force that the actual Parking operation of ratchet-ratchet Parking lockout mechanism is reached may appear at the interval that is lower than Nbmin, exist potential safety hazard when therefore, stopping in the ramp.
Figure 10 is the pedal brake force curve equally, what represent is that Parking lockout mechanism of the present invention sets up braking force at the Nc point (both differences are called as the braking force safety allowance) greater than the required braking force Nbmin of the Parking on the ramp of vehicle technology condition regulation, architectural feature by drg of the present invention is determined, whatsoever when the people carries out the Parking operation, braking force must reach Nc and just can lock, and Nc is a fixed value, like this, braking during standstill has just had the failure-free safety control.
