Terrestrial three-wheeled vehicle i.e. electrical assistance bicycle type tricycle, has mechanical adjustment unit including deformable quadrilaterals, guides, slides and driving cable to adjust ratio of inclination angle and steering angle

摘要

The vehicle has an inclination device permitting inclination of a frame with respect to a vertical direction. Mechanical steering/inclination coupling units are placed between a steering shaft of a steering device and a driven inclination unit (41) of the inclination device to impose ratio between a steering angle and an inclination angle. A mechanical adjustment unit includes deformable quadrilaterals (54, 55), guides (115, 117), slides (116, 118) and a driving cable (119) for adjusting the ratio of the inclination angle and the steering angle.
