Specific embodiment:

In order to clarify the technical characteristics of the invention, below by specific embodiment, and its attached drawing is combined, to this reality It is described in detail with novel.

The embodiments of the present invention is as shown in Figs. 1-2, a kind of tricycle transfer, including a vehicle frame and front-wheel 1, A front-wheel breeches pipe 2 is equipped on the vehicle frame close to 1 side of front-wheel, which is characterized in that a front-wheel is movably equipped in front-wheel breeches pipe 2 Axis 3 is equipped with a steering tube 4 on the vehicle frame of the side of front-wheel breeches pipe 2, a steering shaft 5 is movably equipped in steering tube 4, The vehicle frame of 5 downside of steering shaft is equipped with a drive-shaft tunnel 6, and a transmission shaft 7, the biography are movably equipped in drive-shaft tunnel 6 The upper end of moving axis 7 is connected by universal shaft 8 with steering shaft 5, and the downside of drive-shaft tunnel 6 is stretched out in lower end, in drive-shaft tunnel 6 It is equipped with one first sprocket wheel 9 on the outside of the transmission shaft 7 of downside, is equipped with one and 9 chain 11 of the first sprocket wheel biography in the outside of front-wheel axis 3 The second dynamic sprocket wheel 10.

Due between the steering shaft 5 and front-wheel axis 3 of the utility model not in the same plane, can be by handlebar before car body Lateral deviation is arranged from front-wheel 1, so as to make full use of the space on front side of car body, increases passenger seat on one side in driver's seat, or The space of driver's seat one side is used as him to use；

In addition, being driven between front-wheel axis 3 and transmission shaft 7 by chain 11, compared to jointed gear unit, chain 11 can To slow down transmission, it can not only can slow down to transmit on 3 phase transmission shaft 7 of front-wheel axis and shake, and then slow down therefore caused vehicle Shaking, driving experience is promoted；

Also, the transmission of chain 11 occupied space is less, it is possible thereby to simplify vehicle head structure；

In addition, connecting between transmission shaft 7 and steering shaft 5 by universal shaft 8, shaking can be further eliminated, it can be flexible Differential seat angle between transmission shaft 7 and steering shaft 5 is set, so as to which the pattern of vehicle frame at headstock is flexibly arranged, is met different Design requirement, so that driver is more comfortably manipulated handlebar in driver's cabin.

Further, a chain box is equipped on the outside of the chain 11.It is possible thereby to which chain 11 is encapsulated by chain box Get up, effectively prevent entering foreign matter between chain 11 and each sprocket wheel, the stability that entire chain 11 is driven can be increased, can also be kept The fluency that chain 11 is driven.For the ease of showing that chain drive structure, chain box are not drawn into the accompanying drawings.

In order to realize the adjusting of tricycle handlebar position, movable sleeve is equipped with a set of on the outside of 5 upper section of steering shaft The cross section of pipe 3,5 upper section of steering shaft is rectangle, a rack gear 14 is provided along its length on the outside of 5 upper section of steering shaft, right The position-restricted housing 15 that inside setting is equipped on the outside of the casing 13 at 14 position of rack gear is answered, the outer end of a connecting rod 16 is stretched out The outside of position-restricted housing 15 is simultaneously connected with one handle 17, and inner end is connected with a limit plate 18, and limit plate 18 is meshed with rack gear 14, Intracorporal 16 outer sheath of connecting rod of shell is equipped with a spring 19.It is possible thereby to which handlebar is directly installed with 13 phase of casing, needing to adjust When saving the position of handlebar, it is only necessary to pull out connecting rod 16 by handle 17, make to separate between limit plate 18 and rack gear 14, then Casing 13 is pulled to slide along steering shaft 5, when casing 13 is moved to driver more comfortable position, release handle 17, under the action of spring 19, limit plate 18 moves inward, and engages with rack gear 14, thus by casing 13 and steering shaft 5 it Between lock, driver manipulate handlebar turn to when, 5 upper section cross section of steering shaft be rectangle, casing 13 drive steering shaft 5 rotate.

In order to guarantee the stability of total, steering tube 4, drive-shaft tunnel 6, front-wheel breeches pipe 2 with the direct phase of vehicle frame Even, it is equipped with limit plate 18 on the transmission shaft 7 of the two sides of drive-shaft tunnel 6, corresponding position is equipped with thrust bearing, thus prevents Only transmission shaft 7 is slided along drive-shaft tunnel 6；Likewise, a limit plate 18 is respectively equipped in 4 two sides steering shaft 5 of steering tube, it is right It answers and is respectively equipped with a thrust bearing at the steering tube 4 at position, thus it can be prevented that steering shaft 5 is slided along steering tube 4, this part It is not drawn into figure.

Further, accidentally contact handle 17 so that limit plate 18 is detached from rack gear 14 lead to casing 13 and steering shaft in order to prevent It is arbitrarily slided between 5, the handle 17 is equipped with cavity towards one end of connecting rod 16, and connecting rod activity is deeply to the inside of handle 17 And it is connected with end plate 20；Be equipped with a nut 12 in the hull outside being correspondingly connected at 16 position of bar, be equipped on the outside of handle 17 with The external screw thread that nut 12 cooperates.It is possible thereby to be threadedly coupled between handle 17 and nut 12 in normal condition, can be missed in external force When contact handle 17, prevent handle 17 from connecting rod 16 being driven to slide, when needing the position between adjusting sleeve pipe 13 and steering shaft 5, Can first rotating handle 17, handle 17 is separated with nut 12, then pull out handle 17.

When in use, user rotates handlebar, and handlebar drives casing 13 to rotate, further that steering shaft 5 is driven to rotate, Steering shaft 5 drives transmission shaft 7 to rotate by universal shaft 8, and transmission shaft 7 drives front-wheel axis 3 to rotate in turn, and then drives front-wheel 1 Turning.

It should be noted that wheel arbitrarily shakes in order to prevent, will connected between the first sprocket wheel 9 and the second sprocket wheel 10 Make, chain 11 need to be tightened, it is possible thereby to make the only rotation in handlebar rotation of front-wheel 1；Also, by adjusting the first sprocket wheel 9 And the second transmission ratio between sprocket wheel 10, the corresponding relationship between 1 rotational angle of handlebar rotational travel and front-wheel may be implemented.

Above-mentioned specific embodiment cannot function as the limitation to scope of protection of the utility model, for the skill of the art For art personnel, any alternate modification or transformation made to the utility model embodiment all fall within the guarantor of the utility model It protects in range.

Place is not described in detail for the utility model, is the well-known technique of those skilled in the art of the present technique.
