(pui.j The invention relates to mechanical engineering, namely, automatic gearless transmissions, and can be used in drives of various machines. Inertial-pulsed transmission is known, containing, and coaxially driven with cranks and a driven crank shaft, connecting rods two parallelogram mechanisms, and unbalanced loads pivotally mounted on the driven cranks, interconnected in pairs by coupling with a variable gear ratio 1. This transmission is characterized by complexity, due to the presence of a kinematic connection between loads placed on different driven cranks. The closest in technical dryness and the achieved result to the proposed is inertial-pulse transmission containing coaxial driving and driven crankshafts, connecting their driving and driven connecting rods, forming with the cranks shaft parallelogram mechanisms, and unbalanced loads mounted on the drive shaft. Loads interact with the driven shaft by means of elastic leads 2. However, the presence in this section The transfer of elastic leads and shock loads on the working elements caused by unbalanced loads at the moments of their approaching to the rods due to different linear velocities at the moment of contact reduces its durability. The purpose of the invention is to increase the durability of the transmission. This goal is achieved by the fact that the inertial-pulsed transmission, containing coaxial driving and driven crank shafts, connecting their driving and driving rods, forming parallelogram mechanisms with the cranks, and unbalanced weights on the driving shaft, is equipped with additional rods connecting each corresponding shaft unbalanced load with a crank drive shaft and periodically interacting with driven rods. FIG. 1 schematically shows inertial-pulsed transmission, longitudinal section; in fig. 2 is the same cross section. The transmission contains a leading box-shaped shaft 1 with cranks 2, a driven shaft 3 coaxial with it with cranks 4, the connecting 5 leading them, and 6 driven rods forming the parallelogram mechanisms with cranks 2 and 4, and unbalanced loads 7 associated with the cranks 2 additional rods 8. Transmission works as follows. When shaft 1 rotates and there is resistance on the shaft 3, the loads 7 under the action of centrifugal inertial forces tend to occupy the upper position furthest from the axis of rotation, and the driven rods 6, rotating relative to the cranks 4 of the driven shaft 2, move the loads 7 in lower position, closer to the axis of rotation. When weights 7 move from the upper to the lower position (in the right sector to the lower position (in the right sector of Fig. 2), their centrifugal forces are transmitted through the driven rods 6 to the cranks 4 of the driven shaft 3, forming positive torque pulses on the latter, under the influence of the shaft 3 acquires a rotation in one direction. When the loads 7 move from the lower to the upper position (the left sector of Fig. 2), their potential energy is restored. At the time of the additional connecting rods 8 and the cargo 7 moving together with the driven rods 6, they are in the upper position relative to the crank driven shaft 3 and the linear speeds of the interacting surfaces of these connecting rods are equalized, because at this instant the connecting rods 6 and 8 are aligned in the axial plane and their angular velocities and radii of rotation of the interacting surfaces become equal. split hinge formed by connecting rods 6 and 8, the dynamic loading of the working elements of the transmission is reduced and there is no need to use elastic x leads, which increases the durability of the transmission.
