An alternative option of mechanical stepless impulse type transmission for smallsized transport is con sidered in this paper. The proposed selfregulating automatic stepless transmission allows to signifi cantly improve the technical characteristics of modern CVTs with respect to power and kinematic ranges as well as design simplicity. In this investigation, the theoretical analysis findings of the operating processes dynamics and kinematics in impulse transmission are presented for the ATV case in the MATLab – Simulink visual programming environment. It also contains the project efficiency assessment. The results showed that the proposed scheme of mechanical stepless transmission of impulse type has the property of velocity ratio selfregulation. The transmission provides the vehicle’s smooth acceleration and uniform motion, without the center differential required. At each wheel’s slipping a tractive effort will be transmitted up to the traction limit. As a result the wheel lock is not required in order to improve traction properties. The design of mechanical stepless transmission of impulse type is significantly sim pler and cheaper than that of the existing automatic transmissions, it has smaller internal power loss and high application potential in smallsized vehicles.
