The specific embodiment
Contrast accompanying drawing below, by description, the effect of the mutual alignment between the shape of the specific embodiment of the present invention such as related each member, structure, the each several part and annexation, each several part and principle of work etc. are described in further detail embodiment:
As shown in drawings, the present invention is a kind of hand-braking actuating device, comprise handle 1, support 2, backguy adapter plate 3, tooth plate 13, described backguy adapter plate 3 and tooth plate 13 are movably arranged on the support 2 by rotating shaft, and described tooth plate 13 lower ends set out ratchet 22, and the lower position of described support 2 is provided with the ratchet 4 near tooth plate 13, the connecting pin 7 of described suit positioning spring 8 is connected with ratchet 4, and described ratchet 4 is resisted against tooth plate 13 lower end positions; Described ratchet return bar 10 is movably arranged on the support 2 by return lever pin axle 11.
The ratchet 22 of described tooth plate 13 lower ends is set to laciniation, and position, ratchet 22 next door is ratchet top 23, and the edge on ratchet top 23 still is a smooth structure.
Described ratchet 4 is set to two ends pointed cone structure, and the middle part of ratchet 4 is provided with the ratchet chute 19 that penetrates ratchet 4 bodies, and described ratchet bearing pin 5 passes ratchet chute 19, and ratchet 4 is movably arranged on the support 2.
The pointed cone structure of described ratchet 4 is arranged on ratchet 4 ends, and is set to the outstanding pointed cone structure 21 of ratchet 22 directions.
The other end of described ratchet 4 is provided with the pointed cone structure 21 of projection.
Described positioning spring 8 is sleeved on telescopic connecting pin 7 middle parts, and connecting pin 7 one ends flexibly connect by the position, edge, middle part of its end 24 with ratchet 4; The other end 24 of described connecting pin 7 flexibly connects by spring set pin 9 and support 2.
The described positioning spring 8 that is sleeved on connecting pin 7 middle parts remains compressive state.
Described ratchet return bar 10 is installed in the position near the projection pointed cone structure 21 of the other end of ratchet 4, described ratchet return bar 10 is movably arranged on the support 2 by return lever pin axle 11, and the end of close support 2 centers of described ratchet return bar 10 is resisted against on the backing pin 17.
The both sides of the ratchet return bar 10 of the end of described close support 2 centers are provided with the return bar position-limited lever 18 of the projection of restriction ratchet return bar 10 slewing areas.
Automobile hand braking controller of the present invention is to regulate the position of the fulcrum (promptly by ratchet chute 19 along ratchet bearing pin 5 slide) of ratchet 4 on ratchet bearing pin 5 by positioning spring 8, thereby the rotation direction of control ratchet 4, cooperate tooth plate 13 to realize release and locking, finish hand brake operation.Positioning spring 8 one ends 24 are fixed on the position, edge, middle part of ratchet 4, and the other end 24 is fixed on the support 2 by spring set pin 9, and positioning spring 8 remains compressive state; Be provided with guiding mechanism in the positioning spring 8, make positioning spring 8 along axial motion; Ratchet return bar 10 is fixed on the support 2 by return lever pin axle 11, in handle return process, by being fixed on the backing pin 17 on the tooth plate 13,4 groups on ratchet is got back to initial position; Tooth plate 13 and backguy adapter plate 3 are fixed on the support 2 by rotating shaft 15; Handle pull back spring 16 1 ends link to each other with support 2, and an end links to each other with handle 1, plays the effect that handle 1 is got back to initial position; The chute 25 of tooth plate and the chute 25 of backguy adapter plate slide along the handle locating dowel pin, thus the movement travel of restriction handle 1.
Principle of work of the present invention is:
When handle 1 is positioned at initial condition when hand braking (do not carry out), ratchet 4 force analysis figure as shown in Figure 3, because positioning spring 8 produces pressure P 1, make the ratchet bearing pin 5 of ratchet 4 be positioned at the A point position of ratchet chute 19, and produced size for P1*a, the active moment of direction M1 as shown in Figure 3, the movement tendency that ratchet 4 is produced near tooth plate 13.
In the process that handle 1 upwards spurs, as shown in Figure 3, owing to rubbing effect has produced friction force f1 on ratchet top 23, this power has produced along the power of the ratchet tangential direction of tooth plate 13, has played the effect trend that the A that impels ratchet bearing pin 5 to be positioned at ratchet chute 19 is ordered.
When stopping upwards handle 1, promptly during release lever 1, ratchet 4 is snapped in the ratchet 22 of tooth plate 13.Because 22 pairs of ratchets of ratchet 4 produce pressure, ratchet 4 is slided along ratchet chute 19, become the B point from the A point, as shown in Figure 4.This moment, hand-braking actuating device was in lockup state.
When making progress handle 1 again, ratchet 4 ejects from ratchet 22, removes the Parking state, as shown in Figure 5.Because the pressure P 2 of positioning spring 8, make the bearing pin 5 of ratchet 4 produce the trend that moves to the B place, and produced size for P2*b, the active moment of direction M2 as shown in Figure 5, the rotation trend that ratchet 4 is produced away from tooth plate 13, it is limited to turn to locating dowel pin 6 places, transport to the results are shown in shown in Figure 5, this moment hand-braking actuating device be in released state.Because the effect of handle pull back spring 16 makes handle 1 self-return to initial condition (promptly putting down handle 1).
Be returned in the process of initial condition (promptly putting down handle) at handle 1, the backing pin 17 that is fixed on the tooth plate 13 is stirred ratchet return bar 10, produces thrust P3, forces ratchet 4 to be returned to initial position, as shown in Figure 6.
In conjunction with the accompanying drawings the present invention has been carried out exemplary description above; obviously the concrete realization of the present invention is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present invention and technical scheme to carry out; or design of the present invention and technical scheme are directly applied to other occasions without improving, all in protection scope of the present invention.
