The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done explanation further through embodiment.
Embodiment:
Referring to Fig. 1 and Fig. 2, be used for the fine motion and the brake linkage of 18 ton forklifts, comprise right stop mechanism, left micromotion mechanism and link gear; Said right stop mechanism comprises right brake activation valve pedal 1, brake activation valve valve body 12, is installed in the upper and lower both sides of pedal adapter plate respectively, and the pedal adapter plate is fixed on the cab floor; Said left micromotion mechanism comprises left fine motion pedal 2 and change speed gear box power cut switch 7, is installed in the upper and lower both sides of pedal adapter plate respectively; Improvement is: said left micromotion mechanism also is provided with push rod 4; Push rod 4 is a round bar shape, and the middle part of push rod 4 is provided with clip; Be arranged with spring 8 on the shaft of clip bottom, an end of spring 8 is against the lower edge of clip, and the other end is against on one's body the plate of regulating plate 6.Push rod 4 passes the installation via hole of regulating plate 6, with fixed by nut push rod 4; The bottom of push rod 4 contacts with the control knob of change speed gear box power cut switch 7 upper surfaces; The installation via hole of pedal adapter plate is passed on the shaft top of push rod 4, and the top of push rod 4 contacts (normal condition) with left fine motion pedal 2 bottom faces, but push rod 4 perpendicular movements.
The bottom surface, middle part of left side fine motion pedal 2 is provided with limiting stopper, and limiting stopper cooperates with caging bolt 13 on being installed in the pedal adapter plate, controls the stroke of left fine motion pedal 2.Adapter plate 5 is a zigzag, and the pedal adapter plate is fixed in the upper end, and plate is equipped with regulating plate 6 on one's body, and the lower end is equipped with change speed gear box power cut switch 7, and the control knob of change speed gear box power cut switch 7 is overhanging up; Change speed gear box power cut switch 7 is connected with the input end of change speed gear box control electromagnetic valve through wire harness.
Link gear is one-sided fixed type U type connecting rod 3, and connecting rod 3 one ends are fixed in bottom surface, right brake activation valve pedal 1 top through bolt 11, and the other end is by riding over the bottom surface of left fine motion pedal 2 opposite sides.During use, step on down because connecting rod 3 does not link with left fine motion pedal 2, do not carry out so do not influence braking when right brake activation valve pedal 1; Step on down because connecting rod 3 is stressed by an end that rides over left fine motion pedal 2 bottom surfaces when left fine motion pedal 2, can link to right brake activation valve pedal 1 collaborative work.
Its working process is following:
This device realizes that two actions are car load fine motion and car load braking; Car load braking: when chaufeur is stepped on right brake activation valve pedal 1, the unlatching of control brake valve body 12 in-to-in spools is implemented to brake thereby the oil inlet through the sebific duct jointing comes modulated pressure oil to get into the propons drg with oil outlet; Simultaneously stop lamp switch 10 starts, and brakes low pressure warning switch 9 in addition and starts in real time brake monitoring valve body 12 inside from the size of system's braking oil pressure, to guarantee the reliability of Full Vehicle System work.The car load fine motion: when chaufeur is stepped on left fine motion pedal 2, the bottom face of left fine motion pedal 2 will lift, and push rod 4 moves under the elastic force effect of spring 8 thereupon; Make the bottom of push rod 4 leave the control knob of change speed gear box power cut switch 7 upper surfaces; Change speed gear box power cut this moment switch 7 closures are cut off the power of change speed gear box, the connecting rod 3 of link gear is worked drive right brake activation valve pedal 1 work; Thereby drive 12 work of brake activation valve valve body; And implement the failure-free fine motion, control the usefulness that the path increment of left fine motion pedal 2 can control brake, to realize the speed control of car load kinematic velocity.Reach the purpose of protection change speed gear box simultaneously, and implement failure-free braking or fine motion.
