Oscillating vehicle

Abstract

The invention provides a swing vehicle capable of suppressing the moment of inertia of a power unit and improving riding comfort. The swing vehicle has a body (B), a power unit (P), and a yaw connection mechanism (Jr). The body supports the front wheels (Wf); the power unit supports the rear wheels (Wf); the yaw connection mechanism connects the body and the power unit between. The yaw connection mechanism is composed of a front connection member and a rear connection member, and the front connection member is supported on a vertical swing pivot (29) in a manner capable of longitudinal swing. A yaw restricting device (R) for restricting relative rotation between the front connecting member and the rear connecting member is arranged in the front connecting member, and a suspension device (S) is installed between the vehicle body and the front connecting member. The connecting member (24) is provided with a front protrusion (24E) located in front of the pitch pivot (29), and a part (R2) of the yaw restricting device (R) or a bearing is arranged in the front protrusion (24E) (43).

Description

technical field [0001] The invention relates to an improvement technology of a swing vehicle, which has a vehicle body, a power unit, and a yaw (left and right swing) connection mechanism, wherein the vehicle body supports the front wheels and has passenger seats; the power unit supports the rear wheels and It is driven; the yaw connection mechanism is connected between the above-mentioned vehicle body and the above-mentioned power unit, so that the vehicle body can swing left and right around the yaw axis extending along the front-rear direction of the vehicle (perform yaw). The above-mentioned yaw link mechanism is composed of a front link member and a rear link member, wherein the front link member is supported by a vertical yaw pivot so as to be able to swing up and down (vertical swing), and the longitudinal yaw pivot is supported on the vehicle body. Side: the rear connection member is supported by the front connection member through a bearing so as to rotate about the y...

AI Technical Summary

Problems solved by technology

However, in conventional swing-type vehicles, since the yaw restricting device is accommodated in the front connecting member whose front end is supported on the pitch pivot, the entire yaw restricting device is located behind the pitch pivot. The center of the power unit (system) that swings up and down centered on the pitch pivot will move slightly rearward away from the pitch pivot, thus increasing the moment of inertia of the power unit (system) centered on the pitch pivot

As a result, the followability of the rear wheels supported on the power unit relative to the road surface is reduced (the degree of bumps is increased), making passengers feel uncomfortable
