Problems solved by technology

And when making the vehicle frame toward any one of the left and right to carry out the large-angle inclined walking with a large angle, the front wheel of the outer wheel side in the left and right two front wheels hangs from the road surface, although the front wheel and the rear wheel of the inner wheel side are in the However, in the aforementioned prior art, the front wheel on the inner wheel side is in contact with the road surface in an inclined posture, and there is a possibility that the support of the front wheel on the grounding side may not be sufficient when walking at a large incline at a large angle. sex

Embodiment Construction

[0023] Refer to Figure 1- Figure 9 Describe the first embodiment of the present invention, at first, in Fig. 1- image 3 Among them, the frame F of this tricycle is constituted by joining a front frame FF and a rear frame FR. The front frame FF has a steering column 21 and a tubular connecting frame 22. The connecting frame 22 is connected to the back of the middle part near the lower end of the steering column 21, and extends from the steering column 21 slightly inclined toward the rear and downward. The rear end of the connection frame 22 is fixed to the flange 23 . In addition, the rear frame FR has a tubular main frame 25 having a flange 24 detachably joined to the flange 23 at the front end and extending toward the rear and downward, and a saddle column 26 . A lower end is connected to the rear end of the main frame 25 and extends rearward and upward.

Abstract

A tricycle, the left and right front forks respectively supporting the left and right front wheels freely rotatable are arranged on the left and right sides of the steering column to extend up and down, and are respectively rotatably supported on the left side supported by the steering column and the right side column, the central part of the upper link connecting both ends to the left and right column and the central part of the lower link connecting both ends to the left and right column are rotatably connected to the steering column ; Wherein, the left side and the right side column are arranged obliquely as the distance between the columns on both sides decreases as they go upward, so as to be fully supported by the front wheel on the inner wheel side when walking obliquely.

Description

technical field [0001] The present invention relates to a tricycle. The steering column of the tricycle provided at the front end of the vehicle frame rotatably supports the steering shaft connected to the steering handle, and respectively freely rotatably supports the left and right front forks of the left and right front wheels. The left and right sides of the steering column are configured to extend up and down, and are respectively rotatably supported on the left and right columns supported by the steering column. The two front wheels are steeredly connected to the two front forks, the central part of the upper link that connects both ends to the left and right uprights, and the center part of the upper link that is arranged below the upper link and connects both ends to the left and right uprights. The central portion of the lower link is rotatably connected to the above-mentioned steering column, and supports the driving wheel at the rear portion of the vehicle frame. ...
