<p>It is a carriage (15) gravity centre guidance system for delivery vehicle with three or more wheels. The front part of the carriage (15) is connected with four corresponding steering wheels (5-8) by four steering shafts (1-4). The steering shafts (1-4) are respectively equipped with suspension forks (11-14). On the back of the carriage, there are three rear wheels (9, 10, 16). The carriage controls the steering wheel shaft centre provided between the steering shaft centre and the back wheel shaft centre by the steering shafts and the suspension forks, and takes the steering shaft as shaft centre to make the steering wheel shaft centre to move left and right between the steering shaft and the back wheel shaft centre. The system makes the gravity centre to move right when the controlled steering wheel deviates to right, and the gravity centre moves left when the controlled steering direction deviates to left, thus moving the vehicle gravity centre to the turning direction when the vehicle drives to turn. The system avoids easy side tumbling, and increases the length and width rate of the vehicle to reduce the section of vehicle driving direction and wind resistant force to improve delivery efficiency and lower energy consumption. The system improves the vehicle maneuverability.</p> |
