As Fig. 8 and shown in Figure 9, when this device does not move, ratchet 6 is in released state with ratchet 7, second end 16 is positioned at first tache motorice 17, first end 15 of elastic component 10 and the line of second end 16 are positioned at a side of first rotating shaft 20, and this moment, the application force of elastic component 10 made pallet piece 4 have the trend of moving around first rotating shaft, 20 conter clockwises.Because pallet piece 4 is blocked by rachet 3, so pallet piece 4 can't move.
When depressing pedal 2 when the needs braking, pedal 2 clockwise rotates around second rotating shaft 21, drive the adapter plate 9 that is fixed on the pedal 2 simultaneously and clockwise rotate around second rotating shaft 21, adapter plate 9 drives the pallet piece 4 that is installed on the adapter plate 9 and clockwise rotates around second rotating shaft 21.Second end 16 still is positioned at first tache motorice 17, and first end 15 of elastic component 10 and the line of second end 16 are positioned at a side of first rotating shaft 20, and the application force of elastic component 10 makes pallet piece 4 around the motion of first rotating shaft, 20 conter clockwises, and ratchet 7 slips over the ratchet 6 on the rachet 3.Pedal 2 is stepped on the Parking position, ratchet 7 and ratchet 6 are bonded together, obtain state of kinematic motion as shown in figure 11.
When Panasonic's pedal 2, pallet piece 4 and adapter plate 9 rotate counterclockwise around second rotating shaft 21 under the pulling force of Parking drag-line 24 together, and pallet piece 4 rotates counterclockwise around first rotating shaft 20 simultaneously, and ratchet 7 further engages with ratchet 6.Impeller 23 promotions second end 16 that is structure as a whole with pallet piece 4 moves in tracks groove 11, make second end 16 by flex point 19, second end 16 moves to second tache motorice 18 under the elastic force effect of elastic component 10 then, obtain state of kinematic motion as shown in figure 12, arrow D represents the tension direction of Parking drag-line 24 among the figure.At this moment, first end 15 of elastic component 10 and the line of second end 16 are positioned at the opposite side of first rotating shaft 20, and the application force of elastic component 10 makes pallet piece 4 have the trend of moving around first rotating shaft, 20 cws.Because ratchet 7 is blocked by ratchet 6, so pallet piece 4 can't move.
Want brake off, still need to depress pedal 2.When depressing pedal 2 once more, pedal 2 drives pallet piece 4 around the motion of second rotating shaft, 21 cws, and ratchet 6 and ratchet 7 are disengaged, and pallet piece 4 moves around first rotating shaft, 20 cws under the effect of elastic component 10, and limited 25 blocked, and obtains state of kinematic motion as shown in figure 13.
When Panasonic's pedal 2 once more, as shown in figure 14, pedal 2 resets under the pulling force of Parking drag-line 24, pallet piece 4 and adapter plate 9 rotate counterclockwise around second rotating shaft 21 with pedal 2, first reseting baffle 12 on making second end 16 and being fixed on support 1 contacts, and ratchet 7 contacts with second reseting baffle 26 on being fixed on support 1.Second end 16 that first reseting baffle 12 promotes elastic component 10 moves in tracks groove 11, make second end 16 by flex point 19, second end 16 moves to first tache motorice 17 under the elastic force effect of elastic component 10 then, thereby second end 16 of elastic component 10 is resetted.Second reseting baffle 26 promotes ratchet 7, and pallet piece 4 is resetted, and gets back to state shown in Figure 8 this moment.
The foot-operated holding brake device that the utility model provides is owing to cancelled the waist shaped hole in the pallet piece, by the tracks groove is set on support or pedal, one end of elastic component is moved in the tracks groove, variation by this end position in the tracks groove changes the action direction of the elastic force of elastic component to pallet piece, make ratchet engage or be disengaged, thereby finish the braking of foot-operated holding brake device and reset with ratchet.So the foot-operated holding brake device that the utility model provides has improved the rigidity and the life-span of pallet piece, and then improved the rigidity and the life-span of whole foot-operated holding brake device.
