Among them, the main turn _ is the traditional diamond-shaped frame for the vertical head / read the steering bushing before and after the parallel four-bar linkage, can be two straight = Yixian, lying to take the judging into the steering bushing, = =2_ lie scallops turn _, heart material and vertical flat ΓΓ Μ double front wheel can be automatically adjusted according to the road surface condition, maintain the axis of the steering shaft set Millennium and keep the steering smooth with the steering four-link group, making the driving smooth Easy to control. [Prior Art] The traditional two-wheeled self-driving and three-wheeled bicycles are the Qingqing fixed steering bushings. The steering bushings of the four-wheeled frame are common on the front wheels of two-wheeled bicycles, and the three-wheeled self-propelled bushings are used in two front wheels or two. Wheeled steering bushings, this two-wheeled steering, sturdy and fixed combination method, that is, two wheels can not be used for high and low level riding according to road conditions ==?? Feeling poorly. Some users are not good because of psychological factors. The car is too big because of the car body, hiding does not feel ..., /, has the convenience of two-wheeled bicycle. [New content] The two-wheeled 'single double front wheel three-wheel bicycle structure not only provides double frontality but also has the sense of prison for three-wheeled bicycles, and improves the shortcomings of the car to turn to the ground. Double front wheel three-wheel self-steering 'smooth running, easy to control, improve user riding comfort and connect with 3 frame H' for 'a double front wheel three rounds from ^^ 菱 纽 A,, open ^ shaft sleeve' and double front wheel The steering sleeve, the front and rear parallel four-bar linkages are good: ^ Wei fine miscellaneous group, lying in the head bowl Γ (four) (four) version _ object connected to the steering and vertical movement, keeping the steering smooth, smooth driving, easy to control . For the sake of brevity, the following examples are not intended to limit the present invention. [Embodiment] This creation-type double front wheel three-wheel bicycle structure, please refer to the first diagram of the second-in-one, and the two diagrams of the two-wheel bicycle structure. The dual front wheel three-wheel bicycle structure includes a steering sleeve set (10), a steering shaft set (10), a steering four-link set (10), and a load-bearing four-link set (10). Wherein, the steering sleeve set (10) is composed of a main steering bushing (11), a left steering bushing (10), a right steering bushing (13), and a joint screw ((4) on the steering bushing; the steering shaft Group (20) consists of main steering shaft (8), left front axle (22), right front fork axle (2), upper bowl cover (24), upper ball ring (25), upper bowl (26), lower bowl (27), lower ball ring (28), lower bowl cover (29), handlebar (3〇), faucet (31), shaft cover (32), constipation (33), shaft tension screw inspection (34) ), left front wheel (9), right front wheel (10) and faucet solid bolt (37), steering four-link group (4〇) from main steering shaft link (41), left steering shaft link (42) Right steering shaft link (43), steering link (44), left-hand screw 4 M422524 a J1. ίΔ Ultc year month 曰 i connection connector 47) ball connector (45), right-hand screw Connector (46) Left link connector (48), right link connector (49), left-hand screw fixing nut (5〇) Right-handed screw ϋ ϋ (5)), even lion hood (10), turn _ Link fixing screw (53), steering link left-hand screw (10), steering link right-hand screw (5)) and steering link main screw (10) Shouting; the thin connecting rod set (10) is composed of a front upper connecting rod (61), a front lower connecting rod (62), a rear upper connecting rod (10), a rear lower connecting rod (10), and a connecting rod fixing nut (10); The rod set (10) can be synchronously matched with carrying four continuous fishing (10) for vertical four-link motion' and can be used as a horizontal four-bar linkage alone. The double front wheel tricycle can be carried by the parallel four-bar linkage. The double front wheels can be automatically adjusted according to the road surface to keep the steering shaft group axis parallel, and the four-link group is turned to keep the steering smooth, so that the double front wheel three-wheel bicycle is stable and controlled. easily. In summary, the 'double front wheel three-wheel bicycle structure of this creation can have the advantages of smooth steering, smooth steering, easy handling, etc., and improve user ride comfort and acceptance. It is more effective than the conventional technology, and it has a lot of money. In addition, this creation has not been seen before the application, and there is no doubt about the production. This _ Heikeli law = fixed ^ law to apply for a new type of patent, pray for face to face patent, real sense of virtue.
