Description
Technical field
The utility model belongs to field of mechanical technique, and in particular to a kind of steering mechanism of folding electric vehicle with three wheels.
Background technique
In recent years, tricycle with its environmental protection, safely, quickly the characteristics of liked deeply by people especially the elderly, and it is general
Logical tricycle is compared, and electric folding tricycle is even more the good vehicles that most people receives, it not only rides, and the service life is long, wheelspan
Wide safety and stability, electric drive are laborsaving, can also be directly placed at family, on vehicle or office, not have to worry stolen and wind
Rain shines, and volume after folding is small, collection easy to carry.What existing tricycle used is a front vehicle wheel and two rear wheels,
Steering is directly to be connected with front vehicle wheel by handlebar stem by rotation axis, directly controls front truck rotation by rotating handlebar stem
To, and be directed to the tricycle there are two front vehicle wheels, then the steering mechanism that specifically two front vehicle wheels of control turn to
Summary of the invention
The purpose of this utility model is the presence of the above problem in view of the prior art, proposes that a kind of structure is simple, turns to
The steering mechanism of convenient folding electric vehicle with three wheels.
The purpose of this utility model can be realized by the following technical scheme: a kind of turning machine of folding electric vehicle with three wheels
Structure is set on vehicle body, which is characterized in that vehicle body includes handlebar stem and vehicle frame, two front vehicle wheels is equipped on vehicle frame, before two
Between wheel and handlebar stem be equipped with can control front vehicle wheel steering steering assembly, steering assembly include shaft coupling, rotate gear,
Rack gear and connecting plate, shaft coupling one end are connected with handlebar stem, and the other end is connected with transmission gear, and turning gear wheel and rack is in
In same level and rack gear engages connection with rotate gear, connecting plate there are two and respectively by drive shaft with it is corresponding before
Wheel is connected, and rack gear both ends pass through inter-axle shaft respectively and are connected with corresponding connecting plate, and arcuate socket is offered on rack gear,
Being equipped in arcuate socket arcuately the mobile link block in hole, link block to be hingedly connected with a connecting piece and connection sheet other end hinge
It is connected in rotate gear in succession, stripe board is equipped between two connecting plates, passes through driving front between bar shaped board ends and connecting plate
Axis is connected and is arranged with buffer spring on front propeller shaft.
Compared with prior art, the utility model has the advantage that
It is circumferentially rotated by manipulating handlebar hand-motion handlebar stem, to drive rotate gear to rotate, due to rotate gear
It is to be connected by shaft coupling with handlebar stem, therefore rotate gear can only also circumferentially rotate, so that being engaged with rotate gear
The rack gear of connection is moved to the left or right under the drive of rotate gear, while passing through connection sheet phase between turning gear wheel and rack
Even, rack gear is limited by link block in arcuate socket movement when moving, so that rack gear movement is not linear movement, but is rotated
Moving gear rotation pulls corresponding front vehicle wheel to do leftward or rightward rotation, is convenient for pull connecting plate by inter-axle shaft
Manipulation, stability are high.

Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1 to Figure 2, the steering mechanism of this folding electric vehicle with three wheels is set on vehicle body, and vehicle body includes that handlebar is perpendicular
Pipe 13 and vehicle frame 1 are equipped with two front vehicle wheels 2 on vehicle frame 1, and being equipped between two front vehicle wheels 2 and handlebar stem 13 can control front truck
The steering assemblies that wheel 2 turns to, steering assembly include shaft coupling 3, rotate gear 4, rack gear 5 and connecting plate 6,3 one end of shaft coupling with
Handlebar stem 13 is connected, and the other end is connected with transmission gear, rotate gear 4 and rack gear 5 be in same level and rack gear 5 and
The engagement connection of rotate gear 4, there are two connecting plates 6 and is connected respectively by drive shaft with corresponding front vehicle wheel 2, and 5 liang of rack gear
End is connected by inter-axle shaft 7 with corresponding connecting plate 6 respectively, arcuate socket 51 is offered on rack gear 5, in arcuate socket 51
Be equipped with can the arcuately mobile link block 8 in hole 51, link block 8 is hingedly connected with a connecting piece 9 and 9 other end of connection sheet is hinged
It is connected in rotate gear 4, stripe board 10 is equipped between two connecting plates 6, before passing through between 10 both ends of stripe board and connecting plate 6
Transmission shaft 11 is connected and is arranged with buffer spring 12 on front propeller shaft 11.
When this vehicle needs to turn to, circumferentially rotated by manipulating handlebar hand-motion handlebar stem 13, to drive turning gear
4 rotation of wheel, since rotate gear 4 is to be connected by shaft coupling 3 with handlebar stem 13, rotate gear 4 also can only circumferentially turn
It is dynamic, so that the rack gear 5 for engaging connection with rotate gear 4 is moved to the left or right under the drive of rotate gear 4, turn simultaneously
It is connected between moving gear 4 and rack gear 5 by connection sheet 9, rack gear 5 is limited by link block 8 in the movement of arcuate socket 51 when moving,
So that the movement of rack gear 5 is not linear movement, but rotated around rotate gear 4, so that connecting plate 6 is pulled by inter-axle shaft 7,
Corresponding front vehicle wheel 2 is pulled to do leftward or rightward rotation, convenient for manipulation, stability is high.
10 both ends of stripe board be sheathed on relative to front propeller shaft 11 on, if front vehicle wheel 2 turns to the left, connecting plate 6 exists
It also rotates therewith under the drive of inter-axle shaft 7, since the spacing between two connecting plates 6 is constant, stripe board 10 is opposite at this time
Front propeller shaft 11 positioned at right side moves simultaneously the compression buffer spring 12 on right side simultaneously to 2 direction of right front wheel, to play slow
Punching effect, avoid manipulate handlebar stem 13 turn to when front vehicle wheel 2 there is a situation where swerve.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
