Abstract
The utility model discloses a nose wheel steering mechanism for a pear-shaped multi-wheel scooter, comprising a pear-shaped structure, a spherical restraint device, an arc slide bar, a locking structure and the fixing devices at two ends. The pear-shaped structure is connected with the nose wheel shaft by the spherical restraint device and the arc slide bar, and is connected with a front bar and abeam by the fixing devices at two ends. The rear wheel veers by following the nose wheel which is driven to veer by the pear-shaped structure rotating around the spherical restraint device and sliding along the arc slide bar.
Description
Technical field
The utility model relates to a kind of foresteerage gear, the especially three-wheel of many wheels pedals of Pear-Shaped car or the foresteerage gear of four-wheel scooter.
Background technology
At present, the foresteerage gear of the simplest known three-wheel or four-wheel scooter is connected two angled column types respectively by preceding bar and crossbeam and retrains and realize.This steering hardware principle is simple, with low cost, and too sensitive but it turns to, bad control is turned on one's side during high-speed motion easily; Moreover with the scooter of this mechanism, the problem that the anglec of rotation of bar is not easy to limit before all existing is therefore in very easily landing when object is parked.Other mechanism, as with connecting rod mechanism or the like, all more complicated and underaction, manufacturing cost is also very high, is difficult to meet the need of market.
The utility model content
For easy rollover that overcomes the existence of existing three-wheel or four-wheel scooter steering hardware and the problem that is not easy to park, and other alternative mechanism are too complicated, the problem that manufacturing cost is high, the utility model provide a kind of many wheels pedals of Pear-Shaped car foresteerage gear.This steering hardware can not only be realized turning to apace flexibly, and can effectively lock the pendulum angle of preceding bar, the problem of landing when overcoming rollover and stop.
The technical scheme that its technical matters that solves the utility model adopts is: connecting on the axle of two tires in front, the sphere constraint that can freely rotate is set, connecting a ball again above the spherical constraint, forming the structure that is similar to cucurbit.Top ball is applied on circular arc slide bars of each 40 degree about a section.Wherein the crossbeam of Xia Mian ball and fixed pedestal is connected, and top ball is connected with the fixing preceding bar of handlebar.Two spheroids have been formed a spherical restraint device that limits direction, thereby realize freely turning to of scooter, because the circular arc slide bar is limited in certain radian, have played the effect of locking angle simultaneously.
The beneficial effects of the utility model are: can easily realize freely turning to of scooter front-wheel, the locking of bar slip angle before realizing has like a cork solved the problem that scooter slips when putting easily.It is simple in structure, and is easy to use.
Description of drawings is real
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Fig. 1 is a foresteerage gear schematic diagram of the present utility model.
Fig. 2 is the elevation profile organigram of foresteerage gear principle.
Fig. 3 is the scheme drawing of trailing wheel follower.
Fig. 4 is that car load is implemented organigram.
Fig. 5 is a birds-eye view of the present utility model.
Fig. 6 is front wheel spindle of the present utility model and preceding bar scheme drawing.
Fig. 7 is that the utility model car load turns to scheme drawing.
The specific embodiment
1-front wheel spindle 2-circular arc slide bar 3-blocking device 4-protecgulum 5-bonnet
6-screw fixing device 7-strengthens the preceding bar 9-crossbeam 10-pedal of anchor fitting 8-
The spherical constraint of the spherical axle of 11-12-plastic sleeve 13-.
As depicted in figs. 1 and 2, the Pear-Shaped structure is made of structure protecgulum 4, structure bonnet 5 and plastic sleeve 12, and front and back two parts are by screw fixing device 6 and strengthen anchor fitting 7 plastic sleeve 12 is fixed on around circular arc slide bar 2 and the spherical axle 11.The upper end of Pear-Shaped structure links to each other with preceding bar 8 by screw fixing device 6, and the rear end is connected with crossbeam 9 by screw fixing device 6.Circular arc slide bar 2 and blocking device 3 are fixed on the front wheel spindle 1, and blocking device 3 and circular arc slide bar 2 are one, because the diameter of blocking device 3 is bigger, so played the effect of locked slip.The Pear-Shaped structure is free to slide in scopes of each 40 degree about can be on circular arc slide bar 2.In addition, the Pear-Shaped structure can also be rotated around the spherical axle 11 that is fixed on the front wheel spindle 1, thereby drives the rotation of whole front-wheel.The slip of Pear-Shaped structure and rotation have realized turning to of car load front-wheel like a cork just.In Fig. 2, screw fixing device 6 comprises that 5 are threaded and 4 dowel fixes, and pin respectively has two pins to be welded on the protecgulum 4 and bonnet 5 of Pear-Shaped structure in two junctions up and down, and leaving certain gaps uncovered by the economic plan is mated on preceding bar 8 and the crossbeam 9.
As shown in Figure 3, crossbeam 9 is connected with hind axle by a spherical restraint device 13.Thereby realize that the driven of trailing wheel turns to.
Fig. 4 is that car load is implemented organigram, and Fig. 5 is a birds-eye view of the present utility model, and Fig. 6 is front wheel spindle of the present utility model and preceding bar scheme drawing, has showed the embodiment figure of car load respectively from different perspectives.Fig. 7 has showed the mechanism's state in the steering procedure.
