An alternative option of mechanical stepless impulse type transmission for small-sized transport is presented in this paper. The proposed self-regulating automatic stepless transmission allows to significantly improve s the technical characteristics of modern CVTs in relation to power and kinematic ranges, and also in design simplicity. In this investigation, the theoretical research results on the dynamics and the kinematics of the operating processes in impulse transmission on the example of an ATV are presented in the MATLab – Simulink visual programming environment. An assessment of the project efficiency is also given. The results showed that the proposed scheme of mechanical stepless transmission of impulse type has the property of self- regulating the velocity ratio. The transmission provides smooth acceleration and uniform motion of the vehicle. Applying the interaxle differential is not required. At slipping each of the wheels will transmit a tractive effort up to the limit of adhesion. At the same time the wheel lock to improve traction properties is not required. The construction of the mechanical stepless transmission of impulse type is significantly simpler and cheaper than existing automatic transmissions, has smaller internal power losses and a high potential of application in small-sized vehicles.
