Abstract
The paper considers the issues of improving the driving performance of ground vehicles, which are designed for conditions of wet and rough terrain. The analysis of existing propellers is carried out and their most promising type is proposed - a vibration exciter of directional oscillations. The connection of the proposed impulse-friction propulsion unit with the machine is implemented by means of elastic elements with a soft characteristic.
A description of the results of experimental studies of the assembly condition of a planetary transmission with some satellites is presented, which is performed on the assumption that all speed gears are zero, without moving the tool. This condition severely limits the kinematic possibilities of the transmission. A method is proposed for assembling satellites with an arbitrary gear ratio of a planetary (or simply coaxial) mechanism by manufacturing wheels with a displaced offset device. The problem has been solved for both satellites with one and two crowns.
Thus, the proposed all-terrain vehicle interacts with the road at an acute angle, which eliminates slipping, regardless of the humidity of the supporting surface. At the same time, the machine rests on four wheels and is separated from the impulse mover by a soft elastic element, as a result of which it moves smoothly and does not experience vibration effects. The proposed device has a simple transmission and high efficiency, since the mass of the propeller is significantly less than the total mass of the machine.
Keywords
planetary mechanism, unique satellites, double satellites, wheels splitting rays, the initial rays of the central wheels, the initial rays of the satellites.
