Abstract

PURPOSE:To make improvements in body turnability and rear-wheel self-supporting function by forming a rocking axis of a rolling joint connecting a front body in line with a front-down line passing through a front-wheel grounding part and a rear-wheel axle, in a motorcycle having a broad self-supportable rear wheel and the symmetrically rockable front body too. CONSTITUTION:A rocking axis L of a rolling joint J connecting a front body F to a rear body R free of left-right rocking motion should be set to be front down so as to pass through a tire grounding point A of a front wheel 17 and also pass through an axle 41 of a rear wheel 35 at side view. With this constitution, side inclination of the front body F takes place as making the grounding point A of the front wheel a criterion, and since the rocking axis L passes through the rear wheel 41, a toe-angle change in the rear wheel 35 can be checked. Therefore vehicle turnability and rear-wheel self-supportability both are improvable.

[Prior art 1] A front vehicle body equipped with steerable front wheels and a seat for a passenger is connected to a rear vehicle body equipped with a rear wheel that is wide in the left and right direction and is independent so that it can be moved left and right via a rolling joint. A motorcycle is known from Japanese Unexamined Patent Publication No. 64-1676. The rocking axis of the rolling joint is substantially horizontal when viewed from the side, and is vertically separated from the axle portion of the rear wheel and the ground contact portion of the front wheel.

[Problems to be Solved by the Invention] This motorcycle is equipped with a self-supporting rear wheel on the rear body when traveling in a cory ring with the front body tilted in any direction. In order to tilt the front body to the left and right, it is necessary to lower the left and right elasticity of the rear tires to make them easier to displace, and in the case of a known example, both ends of the wide rear tires are cut diagonally to make it easier to bank. That's what I do.

[Function] In a motorcycle with a front body that swings from side to side, the front body is tilted to the side because the rocking axis of the rolling joint passes through the axle of the rear wheel and the ground contact area of the front wheel below the side view. During operation, the wide rear wheels mounted on the rear body of the vehicle maintain an independent state, suppressing changes in toe angle and making the vehicle easier to maneuver.

[Effects of the Invention] As described above, according to the present invention, in a motorcycle with a left-right swing front body, the swing axis of the rolling joint passes through the axle of the rear wheel and the ground contact part of the front wheel in a downward direction in side view. As a result, when the front vehicle body is tilted to the side, changes in the toe angle of the wide rear wheels on the rear vehicle body that maintain an independent state are suppressed, improving the maneuverability of the vehicle.
