The purpose of the present invention, advantage and feature, by by the non-limitative illustration of preferred embodiment below carry out diagram and
Explain.These embodiments are only the prominent examples of application technical solution of the present invention, all take equivalent or equivalent transformation and
The technical scheme being formed, all falls within the scope of protection of present invention.
Present invention is disclosed a kind of tricycle with two front wheels, as shown in Figure 1, Figure 2 and Figure 3, including main support 9 and
It is located at described main support 9 two front-wheels 92 of both sides and a trailing wheel 93 in front and back respectively, the front end of described main support 9 is provided with t type
Support 96, the both sides of described t type support 96 are respectively symmetrically two front-wheels 92 of setting.Generally perpendicularly it is provided with described main support 9
Headstock support tube 13 and cushion rod 94, described cushion rod 94 is provided with medicated cushion 95.Headstock support tube 13 is provided with headstock 1, institute
State headstock 1 and include tap handle 11 and brake 12.Described headstock support tube 13 is substantially vertical with described main support 9, and with described
Main support 9 is relatively fixed.Certainly, when this tricycle is foldable style, described headstock support tube 13 and described main support 9
Can be folded against.Described headstock support tube 13 be used for supporting headstock 1 and its in also slide and be provided with telescoping tube 16, and rotatably
Be provided with steering tube 14, described telescoping tube 16 passes through the fixation of securing member 18 and described steering tube 14 or unclamps.Described telescoping tube 16
The leading handle in top 11.Like the prior art, described tap handle 11 rotates and described steering tube 14 can be driven to rotate.
The bottom of described steering tube 14 is provided with a swivel plate 15.Described steering tube 14 and the rotation of the swivel plate 15 combination formation present invention
Actuator.
It is provided with link-type between described t type support 96 and front-wheel 92 and turns to bindiny mechanism, described steering bindiny mechanism includes
Described rotary drive and the pull bar 21 of the symmetrical setting being driven by described rotary drive, the one of two described pull bars 21
End is individually fixed on a driving piece 22, and described driving piece 22 includes a pivot 23, and described pivot 23 is arranged on described t type and props up
On frame 96.
Specifically, in conjunction with shown in Fig. 4 and Fig. 5, described driving piece 22 includes the first pivot hole 221, and described pivot 23 passes through
Described first pivot hole 221 on described t type support 96；Described driving piece 22 also includes the second pivot hole 222, front axle
17 pass through described second pivot hole 222 and penetrate and make described front-wheel around front axle 17 rotation to front-wheel 92；Described driving piece 22 is also
Including the 3rd pivot hole 223, described pull bar 21 is articulated with described 3rd pivot hole 223.Described driving piece 22 includes two the
One pivot hole 221, described t type support 96 is located between described two first pivot holes 221, described second pivot hole 222 and the
The same side of the axis x that three pivot holes 223 are formed positioned at described two first pivot holes 221.
Described driving piece 22 also includes the first fixing hole 224, is used for fixing front wheel brake part 19；Described driving piece 22 also wraps
Include the second fixing hole 225, be used for fixing front wheel guard 20.
The equal pivot of opposite side of the pull bar 21 of described symmetrical setting is on same connector 24.Described connector 24
For being mutually inserted symmetrical two halves formula structure together, pivot exists the opposite side of the pull bar 21 of described symmetrical setting respectively
In the wherein half of this two halves formula structure；Described two halves formula structure is plugged in together by a round pin 25；Described rotary drive
