WHEEL SUSPENSION FOR VEHICLES

摘要

Herein provided is a suspension assembly that can constantly maintain a frictional force between the ground contact surface of a rear wheel and the road surface when a vehicle goes around a curve. The suspension assembly includes a suspension mechanism and a linkage mechanism. The suspension mechanism is configured to allow a center-of-rotation shaft of the rear wheel to be displaced with respect to a vehicle body in the vertical direction. The linkage mechanism is configured to link the suspension mechanism and the center-of-rotation shaft such that an axis of roll of the vehicle body is constantly located in the vicinity of the contact ground surface and movement of the center-of-rotation shaft with respect to the suspension mechanism is allowed.

1. A suspension assembly for a vehicle including one or more front wheels and one or more rear wheels, wherein defining one side with respect to an orthogonal line orthogonal to a centerline of a vehicle as a front side and the other side with respect to the orthogonal line as a rear side, the one or more front wheels are provided on the front side and located on both sides with respect to the centerline of the vehicle and the one or more rear wheels are provided on the rear side, the suspension assembly operable for the one or more rear wheels and comprising:
a suspension mechanism configured to allow a center-of-rotation shaft for the one or more rear wheels to be displaced with respect to a vehicle body of the vehicle in a vertical direction; and a linkage mechanism configured to link the suspension mechanism and the center-of-rotation shaft such that an axis of roll of the vehicle body with respect to the one or more rear wheels may constantly be located in the vicinity of a contact ground surface and relative movement of the suspension mechanism with respect to the center-of-rotation shaft is allowed.
