Abstract

The present invention relates to a three-wheeled scooter, that is, a trike, and more particularly, to a cambering device in which the rear pad and the rear wheel are inclined to interlock with the handle stem when the handle stem is swinging from side to side.

The present invention relates to a three-wheeled scooter, that is, a trike in FIG. 1, in particular, when the steering wheel 10 is tilted left and right (when tilting). ) Is inclined cambering apparatus.

In addition, in the related art, since the left and right rear wheels 22L and 22R are parallel to each other in the rearward direction in the cambering direction, the wheels scratch the ground to reduce the speed and wear the wheels. .

In addition, there is a drawback that the camber ring is not directly connected to the propulsion force, but only the camber ring.

Thus, the present invention enables cambering of the trike,
In addition, when the cambering, both rear wheels 22L and 22R are maintained in parallel with each other,

In addition, the left and right inclined motion of the handle stem 10 and the cambering interlocked with the handle stem 10 provide a trike for generating a direct thrust force.

Trike of the present invention, the handle stem 100 is provided with a handle 110 at the top and equipped with a front wheel 120 at the bottom; A pair of left and right pairs of connecting bars 200L / having a rear pad 210 which is connected to the coupling part 300 with the handle stem and extends rearward, mounts the rear wheel 220 at the rear end, and places the foot of the passenger. 200R),

In FIG. 2, the coupling part 300 is disposed with respect to the ground G, (a) placing the upper and lower links (Lu, Ll) on the inclined (A) plane in the advancing direction, or (b) perpendicular (90 °). Place upper and lower links (Lu, Ll) on the

In Fig. 3, the front end L200L 'of the left connecting bar 200L is pivotally coupled to each left end L200L of the upper and lower links Lu and Ll; The front end (L200R ') of the right connecting bar (200R) is pivotally coupled to each of the right end (L200R) of the upper and lower links (Lu, Ll),

In FIG. 3, each intermediate portion L100 of the upper and lower links Lu and Ll is configured to pivotally couple to the handle stem 100. Therefore, the coupling portion 300 constitutes a four-section linkage (linkage) to exercise in the form of a parallelogram. The rear end left and right rear wheels 220L and 220R extending from the front ends L200L 'and L200R' of the left and right connecting bars are interlocked when the handle stem 100 is inclined to the left or right side. Then, cambering is performed in which tilting is performed. At this time, the left and right tilts are performed according to the parallelogram principle, and thus the mutual parallelism between the rear wheels is maintained. When the upper and lower links Lu and Ll are disposed on the inclined surface A as shown in FIG. 3A, when the handle stem is inclined to the left or right side as shown in FIG. 5, the connecting bar side is proportional to the inclination A angle. Slightly lateral movement (M) serves. If the movement of the connection bar 200 is fixed to the reverse side the handle stem 100 is moved to the side at this time, if the steering wheel 110 to move to the side to move the rear wheel 220 to the front wheel 210 Propulsion occurs when the ground is cut diagonally.

Meanwhile, referring to FIG. 3 (C) in the coupling part, coupling shafts are formed on upper and lower links Lu and Ll and front ends L200L 'and L200R' of the left and right connecting bars. Combined. In general, the coupling shaft of the four-section linkage is composed by coupling the links to the pin shaft (P).

In summary,

In the configuration of the coupling portion 300 in Figure 3, the link coupling portion 310 is formed behind the handle stem (100); The intermediate portions L100 of the upper and lower links Lu and Ll are axially coupled / rotated and coupled L100 'one by one; Left and right front ends (L200L ', L200R') of the left and right connecting portions are pivotally coupled to left and right ends of the upper and lower links (Lu and Ll).

In FIG. 4, the coupling part 300 has link coupling parts 310: 310 ′ and 310 ″ formed one by one before and after the handle stem 100, and the link coupling parts 310 ′ and 310 ″ are formed one by one. ), The intermediate portion L100 of the upper and lower links Lu and Ll rotates one by one.

According to the invention, according to the parallelogram principle of the front side coupling portion of the left and right connection bar, the inclination of the rear end of the connection bar, that is, cambering is made, and in addition, both rear wheels are parallel to each other according to the parallelogram principle during the cambering. State can be maintained.

Propulsion can be generated from the left and right tilt motion of the handle stem and the camber ring interlocked with the handle stem, thereby enabling a large acceleration in addition to the body reaction.
