Description

A kind of front-wheel synchronous turning device
Technical field
The utility model relates to a kind of steering unit for front wheels, relates generally to that a kind of structure is simple, convenient and swift, the front-wheel synchronous turning device of manual dexterity.
Background technology
Traditional steering unit for front wheels design is lengthy and tedious, complex structure, less stable, not easy care, and this front-wheel synchronous turning device structure is simple, is easy to operation, reduces the cost manufactured with safeguarding.
Summary of the invention
The technical solution of the utility model is: a kind of front-wheel synchronous turning device, is made up of platform, DC machine, gear, tooth bar, chute, fixed link, two rotating disks, two pull bars, two steering shafts, two sleeves, two supports and two front-wheels; Described DC machine is fixed on the positive front end of platform; Described gear is fixed in the rotating shaft of DC machine; Described rack and pinion occlusion, and be positioned at immediately below gear; Described chute is welded on below tooth bar; Described fixed link is positioned at platform front end and through chute; Described two rotating disks are individually fixed in the two ends of fixed link; One end of described two pull bars is connected with the two ends of chute respectively, and the other end is connected with rotating disk respectively; Described two steering shafts are embedded in two rotating disks respectively; Described two sleeves are enclosed within two steering shafts through platform perforation; Described two supports are separately fixed at the lower end of two steering shafts through sleeve; The rotating shaft of described two front-wheels is connected with two supports respectively.
Described gear cw or rotate counterclockwise under the drive of DC machine, and by the sway of tooth engaged band carry-over bar, thus make rack synchronous drive the sway of chute; Described two pull bars pull two rotating disks respectively under the sway of chute, make two rotating disk synchronous axial system certain angles; Described two steering shafts drive the rotation of two supports under the rotation of two rotating disks, thus realize synchronously turning to of two front-wheels.
Effect of the present utility model is: the rotating of the DC machine gear of platform front end controls the sway of tooth bar, by driving the movement of two pull bars to make steering axes with the chute of rack welding, thus make two front-wheels deflect certain angle in the same way, realize synchronously turning to of front-wheel so quickly and easily.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In FIG, 1. platform, 2. DC machine, 3. gear, 4. tooth bar, 5. chute, 6. fixed link, 7. rotating disk, 8. pull bar, 9. steering shaft, 10. sleeve, 11. supports, 12. front-wheels.
Detailed description of the invention
With reference to Fig. 1, a kind of front-wheel synchronous turning device, is made up of platform 1, DC machine 2, gear 3, tooth bar 4, chute 5, fixed link 6, two pull bars 7, two rotating disks 8, two steering shafts 9, two sleeves 10, two supports 11 and two front-wheels 12; Described DC machine 2 is fixed on the positive front end of platform 1; Described gear 3 is fixed in the rotating shaft of DC machine 2; Described tooth bar 4 is engaged with gear 3, and is positioned at immediately below gear 3; Described chute 5 is welded on below tooth bar 4; Described fixed link 6 is positioned at platform 1 front end and through chute 5; Described two rotating disks 7 are individually fixed in the two ends of fixed link 6; One end of described two pull bars 8 is connected with the two ends of chute 5 respectively, and the other end is connected with rotating disk 7 respectively; Described two steering shafts 9 are embedded in two rotating disks 8 respectively; Described two sleeves 10 are enclosed within two steering shafts 9 through platform 1 perforation; Described two supports 11 are separately fixed at the lower end of two steering shafts 9 through sleeve 10; The rotating shaft of described two front-wheels 12 is connected with two supports 11 respectively.The utility model structure is simple, easy to operate, can realize synchronously turning to of two front-wheels 12.
Described gear 3 cw or rotate counterclockwise under the drive of DC machine 2, and by the sway of occlusion tooth bar 4 with carry-over bar 4, thus make tooth bar 4 synchronously drive the sway of chute 5.
Described two pull bars 7 connect chute 5 and two rotating disks 8 respectively, and under the sway of chute 5, pull two rotating disks 8, make two rotating disk 8 synchronous axial system certain angles.
Described two steering shafts 9 connect two rotating disks 8 and two supports 11 respectively, and drive the rotation of two supports 11 under the rotation of two rotating disks 8, thus realize synchronously turning to of two front-wheels 12.
Mode of operation of the present utility model is as follows: when the rotating shaft cw of DC machine 2 or when rotating counterclockwise, DC machine 2 driven gear 3 rotates, gear 3 is with carry-over bar 4 to move to the left or to the right by occlusion tooth bar 4, tooth bar 4 synchronously drives chute 5 to move to the left or to the right, chute 5 moves to left or moves to right and pulls two pull bars 8 make two rotating disk 7 conter clockwises or rotate clockwise certain angle, rotating disk 7 rotates and drives steering shaft 9 rotation that support 11 is rotated to the left or to the right, thus realizes left-hand rotation or the right-hand rotation of two front-wheels 12.
