Described the first sleeve 9 comprises that coaxial sleeve is located at the first set cylindrical shell 9-1 on axle 15, and with integrated two the engaging lug 9-2 of this first set cylindrical shell; Two engaging lug 9-2 lay respectively at first set cylindrical shell 9-1 axis both sides, in this example, two engaging lug 9-2 are located along the same line, and line is arranged symmetrically with centered by first set cylindrical shell 9-1 axis, one of them engaging lug 9-2 and fine motion connecting rod 12 are hinged, and another engaging lug 9-2 and linkage section 6-1 are hinged.
Described the second sleeve 14 comprises that coaxial sleeve is located at the second sleeve body 14-1 on axle 15, and on this second sleeve body, one is processed with a hinged ear 14-2 hinged with brake connecting rod 17.
Described link gear comprises the driving link 16 be arranged on first set cylindrical shell 9-1, and be arranged in the second sleeve body 14-1 upper, with the driven member 19 of this driving link coupling; In this example, described driving link 16 comprises the fixed block 16-1 be welded on first set cylindrical shell 9-1, offer a tapped bore on this fixed block and this adjusting bolt of adjusting bolt 16-2 that is threaded is arranged over against driven member 19, under free state, leave certain gap between adjusting bolt 16-2 and driven member 19, in actual the use, can regulate as the case may be the size in this gap to adapt to different needs of work.
The principle of work of the present embodiment is as follows: when stepping on brake pedal 2 and braked, brake connecting rod 17 drives the second sleeve 14 by hinged ear 14-2 and rotates counterclockwise (with Fig. 2 position benchmark), due to separate between the first sleeve 9 and the second sleeve 14, only by unidirectional rigidity link gear contact, and the interlock of this link gear has one-way, can only drive brake pedal 2 actions by 1 action of fine motion pedal, otherwise not all right, therefore, now the first sleeve 9 can not rotate, and fine motion pedal 1 can not move too.
When stepping on fine motion pedal 1, fine motion connecting rod 12 drives the first sleeve 9 by engaging lug 9-2 and rotates counterclockwise (with Fig. 2 position benchmark), thereby drive pull bar 6, moves up; Simultaneously owing between adjusting bolt 16-2 and driven member 19, leaving certain gap, the second sleeve 14 temporarily can not rotate, after the first sleeve 9 turns over certain angle, adjusting bolt 16-2 withstands driven member 19, if now the first sleeve 9 is rotated further, the second sleeve 14 will rotate counterclockwise (with Fig. 2 position benchmark) under driven member 19 effects, and pulls brake pedal 2 to move downward by brake connecting rod 17, thereby realizes braking.Moving past transiting rod 10 in journey on pull bar 6 can rotate under the second spring 8 effects, be that transiting rod 10 is offered on through hole one end and moved, the other end (with the first connecting rod coupling end) moves down, thereby drives the rotating shaft rotation of jogging sensor 3 by first connecting rod 11 and second connecting rod 13, when transiting rod 10 turns to while contacting with position-limited lever 4, continue to step on fine motion pedal 1 downwards, the first sleeve 9 continues to rotate counterclockwise, on continuing, moves by pull bar 6, while is due to the position-limiting action of position-limited lever 4, transiting rod 10 can not rotate, same jogging sensor 3 can not rotate yet, now the second spring 8 is further compressed, still can drive brake pedal by fine motion pedal 1 and realize braking, therefore in the stroke range of fine motion pedal 1, no matter the stroke that fine motion pedal 1 is stepped on is how much to guarantee that jogging sensor 3 rotates all the time in the scope of setting, the pedal of fine motion simultaneously 1 can drive as required brake pedal 2 actions and realize braking in its stroke range.
