Vehicle roll driving device and active roll tricycle using same

The invention relates to a vehicle roll driving device and an active roll tricycle using the same, belongs to the technical field of vehicle chassis, and researches the roll driving control technology of an active roll vehicle. According to the key technical measures of the vehicle roll driving device, a torsion bar spring is connected in parallel on the basis that an actuating rod series-connection double shock absorber drives a vehicle to roll, and the actuating rod series-connection double shock absorber and the torsion bar spring series-connection double connecting rods jointly drive the vehicle to roll, so that roll angle response lag caused by a spring damping system of the shock absorbers is restrained. The nonlinearity of a roll motion transmission system is reduced, and the roll response speed of the vehicle is increased. The driving speed of the active side-tipping vehicle on the curve is increased, and the safety and comfort performance of the active side-tipping vehicle are improved. 本发明涉及一种车辆侧倾驱动
