Since the front-wheel-drive bicycle can maintain the front-wheel operating portion j so as to be rotatable in the direction around the axis, in the state of Λ± „ _, the driving force of the link e is driven by the rotational driving force of the link e. In the flat road surface, it is possible to achieve a stable turning without deceleration. Patent Document 1: Japanese Laid-Open Patent Publication No. 2001-337781 [Summary of the Invention] However, when traveling on a road surface having irregularities and crossing a step, especially in a diagonal direction When the step is different, the front wheel g is easily bounced to make the direction out of control. As a result, there is a problem that the rudder direction deviates from the step direction and it is difficult to overcome the step difference. Even 200922830, because the direction of the driving force is fast.., τ文置~0 The risk of dumping on two-way bicycles due to loss of balance is also very high. Also, because there will be a larger motorcycle, the tires of the previous wheel g, so the explosion: the door acts on the drive and turns to the problem The frequency of occurrence is also high. Especially in the case of a puncture, due to the instant 'turn, the county's long-term loss of knowledge, but still continue to drive the rotation, so the valley is likely to cause falls or collisions. Is provided to remain under the front tube The two ends of the axle have a relative rotation of heat - the front wheel, and basically the longitudinal direction; = the means to rotate the front axle, with the purpose of crossing the step difference. The two 'can be turned with a small radius before the two-wheeled bicycle In order to achieve the above objective, the right main body has: in the invention of the first item in the front end portion, before the front tube is under the branch, the broken branch is held in the main 〇..., both ends and there is no relative rotation - the front wheel, After the wood is rotated, the end is rotatably supported by the rear wheel of the main bracket, and the driving means for driving the wheel is operated.

Further, the first passive bevel gear 21 meshes with the other hand: the driving bevel gear 22, and transmits the rotation of the relay rotating body 23 to the vertical driving body 13. In addition, the second brewing #* hi 4 people. The second drive gear 24 is disposed in engagement with the second bevel gear 25, and the two bevel gears constitute a drive coupling means 14 for transmitting the rotation of the longitudinal drive body to the front wheel axle 4. Since the drive connecting means 14 is included and the bevel gear transmission is driven at the lower end of the longitudinal driving body **q + L & body 13, the advantage is that the driving force loss can be suppressed and the rotation can be smoothly transmitted. Since the driving means 7 is configured as described above, the rotational driving force generated by the rider stepping on the pedal 52 is transmitted from the link 46 through the endless key strip W to the sprocket 2QS of the relay rotating body 23, and then passed through the sprocket The first passive bevel gear 21 that drives the bevel gear 22 rotationally drives the longitudinal drive body 13. Further, the rotation of the longitudinal driving body 13 is further transmitted to the front wheel shaft 4 through the driving connection means μ, so that one of the integral mountings is simultaneously driven by the front wheel axle 4 to travel. 15 200922830 The n'J top J travels on the road surface, so it can travel smoothly and safely even under the harsh running conditions including serious irregularities. For example, when entering the step from the right oblique direction, the right front wheel 5 will be resisted by the pushback when it first contacts the step difference. 'But since the left front wheel 5 has not yet reached the step, the front wheel 5 is driven to rotate on the flat road j, so the side slip can be prevented and the right side can be pushed up. The front wheel 5, so the right wheel 5 will not be bounced off by the step and can be stably spanned. Then, since the right front wheel 5 has been driven and is indeed grounded to a higher road surface to prevent side slip: the left front wheel is not bounced off by the step and can smoothly cross the step and travel. In the present embodiment, as shown in the above description, since the driving force of the flute provided on the end side of one of the axles 4 extending from the level I of the bearing 6 is from the longitudinal driving body η, in particular: the bevel gear 25 transmits When pedaling, etc., will operate two =: when the = travel and the handle 9 is driven so that (4) the instability 2 is generated to make the hand c ^ and ring, however, since the pair of front squats on the road can prevent the (four) axis i 1 due to the aforementioned torque For example, as shown in Fig. 7 (4), when the movement starts in the straight forward state, the handle is operated to advance straight, and then the progress is 缋, = performance. Further, even when the front side wheel 5 is blown up, the function of driving the snake wheel can be continued, and the safety of the two wheels on the other side is excellent. b and then "stop falling, so in this form, as shown in Figure 3, the wheel centerline interval LA f 刖 wheel 5, 5 is set to mm. If not", 〇 ~ 2 〇 0 _, and The ideal is 7〇~15〇, the right is less than 50mm, and the above-mentioned step spanning force suppression effect is sufficient for the knives of the rudder shaft 11 to be fully utilized, and the space for housing the bearing box W to be connected 16 200922830 means 14 insufficient. On the other hand, if it exceeds 2 inches, the rotation speed of the outer front wheel 5 and the inner front wheel 5 is too large when turning, and slippage occurs on the ground to make the sailability unstable. Further, in the above-described embodiment, since the front tube 2, the vertical steering shaft portion ι, and the vertical driving body 13 are formed to be vertical, even if it is a sharp turn close to 90 degrees as shown in Fig. 7(B), It's easy to operate the handle, so even a weaker rider can easily use it. Even as shown in Fig. 7(c), by rotating the handle 9 more than 9 degrees to drive the front wheel rearward, it is also possible to retreat. As described above, since the front wheel 5 of the first two-wheel bicycle is driven by the steering means & ^ and simultaneously driven by the driving means 7, the handle can be operated in a 360-degree direction. Moreover, since the front wheel 5 is driven by the wire, the performance of the cabin is excellent, and the high-precision driving operation such as lateral shifting is simple. Therefore, it can be applied to, for example, elderly people, physically handicapped persons, and the like, which are used for low-speed traveling for transportation and are suitable for small-radius bicycles. Fig. 8 is a view showing another embodiment. The dissimilar contents are explained below, and the remainder: the same symbols are given only to the main components shown in the drawings. In the first two-wheeled bicycle i of this embodiment, the front wheel 5 and the rear wheel are used in a size of about 2 〇 to 28 inches. Therefore, the second system is disposed at a high position and extends rearward from the front tube 2 to the lower side of the tube 31. 31F is continuous at the rear and is formed by extending the lower portion of the tube 31B with a negative slope of %~correction. Further, the endless chain 18C is engaged with the pair of auxiliary sprockets 48, 48 and spanned between the sprocket 20S provided in the front tube 2 and the link 46. Fig. 9 is no longer another embodiment. In the present embodiment, the main bracket 3 17 200922830 10, the longitudinal driving body 13 and the inclination angle α are formed so as to be formed in the front end portion of the tube 2, and the vertical steering rudder portion is inclined backward by 5 to 10 degrees at the same inclination angle α. . As mentioned in the previous paragraph, the front end of the front wheel 4 is cut at the lower end of the station. When the front wheel 5 is at the handle, since the outer front wheel 5 can float with the rotation angle, only the inner side The result of the front wheel 5 is as follows. 'Because the grounding part does not slide when the f is turned, it is possible to smoothly bend without using the differential device. In addition, the oblique angle is below 1G degree and the front angle of the longitudinal shaft portion is also formed as a small angle below:, so that the (four) degree of the handle operation during traveling is not damaged. Further, since the inner front wheel 5 in which the load is concentrated during the turning is liable to be recessed, it is preferable to use the high-pressure tire having a slight depression as the front wheel 5, so that the outer front wheel 5 can float. Further, as described above, since the two wheels 5 are grounded during the straight line travel, it is possible to prevent the handle from being steered by the torsion force generated by the boat shaft i when the pedal is stepped on. Further, the above description is illustrative of embodiments of the present invention. Therefore, the technical scope of the present invention is not limited thereto, and various modifications other than the above-described embodiments are also included.
