Abstract
The utility model discloses a manpower tricycle steering device. The manpower tricycle steering device is characterized in that the handle bar of the manpower tricycle is fixed to the upper end of the column of the handle bar, a front fork is under the front pipe of the tricycle frame, the column of the front fork passes through the front pipe of the bicycle frame from the lower part, and the end of the column of the front fork extended and fixed movably with the front pipe of the tricycle frame; a handle bar holder is fixed on the upper pipe of the tricycle frame, and the column of the handle bar is vertically and movably fixed in the handle bar holder; the column of the front fork and the column of the handle bar are connected with the double-rocker mechanism of a planar-linkage mechanism. The manpower tricycle steering device solves the problems of the unreasonable arrange of the restriction of the position on the active top of the handle bar, or the long distance between the saddle and the handle bar.
Description
Affiliated technical field
The utility model relates to by the manually driven three-wheel vehicle, especially a kind of front-wheel steering device of manual tricycle.
Background technology
The front-wheel steering device of traditional manual tricycle is to be installed to cooperate by the preceding pipe of handlebar parts, front fork parts and frame part to form, also movable fixing in the preceding pipe of front fork column insertion frame part, handlebar is from be inserted in front fork column termination, and the upper end screws nut both are fixed.The steering hardware of the manual tricycle of this structure just is difficult to arrange when the position is excessive between handlebar top position limited or saddle and the handlebar running into.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, can be in the handlebar top position all can reasonable Arrangement when the position is excessive between limited or saddle and the handlebar the manual tricycle steering hardware.
The technical scheme that its technical matters that solves the utility model adopts is: handlebar is fixed on the upper end of handlebar column, front fork is before vehicle frame under the pipe, the pipe medial end portions was stretched out before the activity of front fork column was fixed on vehicle frame, fixing handlebar seat on top tube, the handlebar column vertically movable fixing wherein, be connected with planar linkage mechanism between front fork column and the handlebar column.
Described planar linkage mechanism is a double rocker mechanism, and two rocking bars center is separately fixed on front fork column and the handlebar column, and two ends flexibly connect with two connecting rods respectively.
Be respectively equipped with bearing up and down in the described handlebar seat, fixing on top tube with anchor ear.
The beneficial effects of the utility model are that the position of handlebar can be settled on top tube as required, double rocker mechanism reliable transmission, simple.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural representation.
Fig. 2 is the birds-eye view after Fig. 1 removes handlebar.
1. front forks among the figure, 2. time retaining 3. descends bowl, 4. preceding pipe, 5. go up retaining, 6. go up bowl, 7. spring cotter, 8. rocking bar, 9. pin, 10. front fork column, 11. nuts, 12. pull bars, 13. nut, 14. handlebar columns, 15. nuts, 16. handlebars, 17. grip, 18. bolts, 19. sleeve pipes, 20. bearings, 21. top tube, 22. nuts, 23. plates, 24. anchor ears.
The specific embodiment
In Fig. 1, Fig. 2, following retaining (2) is contained on the axle journal of front fork column (10), reinstall down bowl (3) and steel ball, front fork (1) is managed under (4) before being installed in vehicle frame, front fork column (10) under pass before the vehicle frame pipe (4) and stretch out to pack into and go up bowl (5) and steel ball and screw on retaining (6) and tighten, rocking bar (8) is radially fixing with both with key from being inserted in front fork column (10), from front fork column (10) upper end nut (11) axial restraint; The handlebar seat is fixed on the top tube (21) by anchor ear (24), 2 blocks of plates (23) that are welded with bearing sleeve (19) use 4 pieces of bolts (18) and nut (22) to fix relatively, bearing (20) is housed in the sleeve pipe (19), handlebar column (14) is inserted and secured in 2 bearings (20), its another rocking bar of middle part (8) is radially fixing with both from being inserted in key, with nut (13) axial restraint, handlebar (16) and fixing with nut (15) is inserted in handlebar column (14) termination, and handlebar (16) grip is with grip (17); Groove is put into for fluting, connecting rod (12) activity that band iron is made at 2 two ends in rocking bar (8) two ends, passes both movable fixingly with pin (9), and locks with spring cotter (7), can change the needs of connecting rod (12) length adaptation diverse location.
Like this, when the bicyclist rotates handlebar, the handlebar column drives rocking bar on it along with rotation, and double rocker mechanism plays a role above Motion Transmission to the front fork column, and then makes front fork drive front-wheel steering.
