The utility model compared with prior art has the following advantages:
1, this device adopts manual operation, and mechanical system turns to, and makes to turn to more reliably, and manually controls control stick, makes 90 ° of four road wheel original place synchronous rotaries, keeps fuselage not to be subjected to displacement, and height of C.G. does not change.
2, adopt bracing wire with control stick and steering mechanism's transmission, therefore make overall structure lightly convenient, with low cost.
In sum, the utility model is simple in structure, cost is low, turn to reliable, light and handy convenience.
Description of drawings:
Fig. 1 structural representation of the present utility model.
The vertical view of Fig. 2 steering mechanism of the present invention.
Embodiment:
Below in conjunction with accompanying drawing, further describe the embodiment of this patent.
Referring to Fig. 1, be provided with four running gears on chassis 12, control stick 1 bottom is hinged on the chassis, middle hinged with bracing wire dop 2, bracing wire dop 2 pins four bracing wires (one, two, three, No. four bracing wire), and bracing wire is enclosed within guiding flexible pipe 4, by guiding flexible pipe 4, four steering mechanism of leading respectively, the other end of four bracing wires is fastenedly connected with four rolling discs after being wound around respectively four rolling discs, one circle, and rolling disc and back shaft are fastenedly connected.Left lateral is walked mechanism 14 and right lateral and is walked mechanism 13 and be arranged on chassis 12, left lateral is walked mechanism 14 and is connected mechanism 13 with right lateral and is connected with left support axle 7 end of being connected with the right support axle on the bearing holder (housing, cover) 11 that is arranged on chassis 12 respectively, be separately installed with left-hand rotation Moving plate 6 and right-hand rotation Moving plate 10 on the other end of left support axle 7 and right support axle 9, the position-arresting disk 8 that limits left-hand rotation Moving plate 6 and the right-hand rotation Moving plate 10 rotation number of degrees is equipped with respectively in left-hand rotation Moving plate 6 and right-hand rotation Moving plate 10 belows.Left return spring 17 1 ends are fastenedly connected on left-hand rotation Moving plate 6, the adjustable connection of the other end, be connected on chassis 12, right return spring 15 1 ends are fastenedly connected on right-hand rotation Moving plate 10, the adjustable connection of the other end is connected on chassis 12, and drive motors 16 is connected with right driving mechanism 13, two other running gear on chassis 12 and left lateral are walked mechanism 14 and right lateral and are walked mechanism 13 and be symmetrical arranged, and structure is identical.
Operation principle
when manually control stick 1 from the position 1 around control stick 1 bottom pin joint to the position 2 when rotating, in the middle of control stick, hinged bracing wire dop 2 is put the right with control stick, bracing wire dop 2 pulls one, two, three, No. four bracing wires, a bracing wire 3 and No. four bracing wires 5 are by guiding flexible pipe 4, lead respectively left-hand control 14 and right turn mechanism 13, a bracing wire 3 pulls left-hand rotation Moving plate 6 clockwises to rotate, left-hand rotation Moving plate 6 drives left support axle 7 clockwise rotation together, the left-hand rotation Moving plate 6 left return springs 17 of stretching, left support axle 7 drives left-hand control 14 clockwise rotations, when turning to 90 °, position-arresting disk 8 blocks left-hand rotation Moving plate 6, left-hand rotation Moving plate 6 stops operating, left-hand control 14 stops operating simultaneously.No. four bracing wires 5 pull right-hand rotation Moving plate 10 inverse clocks to rotate, right-hand rotation Moving plate 10 drives right support axle 9 inverse clock rotation together, the right-hand rotation Moving plate 10 right return springs 15 of stretching, right support axle 9 drives the 13 inverse clocks rotations of right turn mechanism, when turning to 90 °, position-arresting disk 8 blocks right-hand rotation Moving plate 10, and right-hand rotation Moving plate 10 stops operating, and right turn mechanism 13 stops operating simultaneously.Complete to this right turn mechanism 13 and left-hand control and turn to 90 °, control stick 1 rotates to position 2, automatic locking simultaneously.Two other running gear on chassis 12 is completed with identical action and turn to 90 ° simultaneously.
