Abstract

An inertial pulse variator comprises a flywheel on which are fixed the pins of satellites, it is connected to a driving shaft, and the satellites on which the eccentrics are fixed are coupled with the central pinion, this is fixed on the driven shaft. The eccentrics are placed on the pins of the flywheel with possibility of free, though restricted rotation of those with respect to the satellites; supports are included, those are fixed on the satellites; and each pair of the eccentrics has possibility of sequential transfer of torque.

Description

Description of the invention

Engineering branch: mechanical engineering. This is a car, tractors, gearboxes and all other technical means for which there is a technical and economic rationale for using this variator.

Technical level. Currently, vehicles use gearboxes and gearboxes with both manual and automatic switching to change speeds and torque.

The closest analogue is the inertial pulse variator of the Romanian engineer-inventor Constantinescu. This variator is described in the book INERTIA by N.V. Gulia, "Nauka" publishing house, Moscow, 1982. Which consists of 70 flywheel 1 on which the fingers of 7 satellite gears 5 are fixed, connected to the drive shaft Z. The satellites 5 engage with the central gear 2 mounted on the driven shaft 6. A massive link 4 with an eccentrically located center of mass is immovably fixed to each satellite /hereinafter referred to as an eccentric/.

The negative aspects of this variator are that the eccentrics are immovably fixed on the satellites and when they rotate, they give the central gear a moment of different sign, and to "straighten" it, it is necessary to use a 72 overrunning clutch, which, according to its technical characteristics, cannot withstand long-term operation. | also, synchronous operation with eccentric pulsations on the driven shaft.

The essence of the invention. The invention is based on the task of improving the inertial pulse variator by means of constructive modernization of the analogue, that is, limited semi-free rotation of the eccentric relative to the satellite is used, which is achieved by placing it on the finger of the flywheel and using a stop fixed on the satellite through which the eccentric transmits the impulse of the moment of the satellite and further to the central gear. This moment impulse is transmitted only when the eccentric moves in the centripetal direction with the help of a stop, and during eccentric movement the eccentric has the possibility of free overtaking of the satellite, while there is no moment transmission, and the circular displacement of each pair of eccentrics allows the moment to be transmitted from them in sequence, which significantly improves the variator's characteristics. 29 The essence of the invention is explained by the drawing.

Information that confirms the possibility of implementing the invention. The variator is in a static state.

The inertial pulse variator consists of a flywheel 1, on which fingers 7 are fixed, on which satellites 5 and eccentrics 4 rotate freely, which is connected to the drive shaft 3. The satellites are connected to the central gear 2, which is mounted on the driven shaft 6.

Each satellite has a stop 8. o

The variator in action. "AND

When rotating the flywheel 1 with fingers 7, the satellites 5 rotate and "roll" around the central gear 2 and with their stops rotate the eccentrics 4, which, thanks to the centrifugal force of energy, create resistance when they turn in the centripetal direction, and this resistance is transmitted through the satellites 5 to the central gear 2, which, as a result, rotates. When the eccentrics 4 move radially, they move away from the stops under the action of the center of rotational force and do not transmit the torque through the satellites 5 to the central gear 2. When the eccentrics reach their maximum distance from the center of rotation, they slow down, and the satellites, which have a more stable motion, catch up them and their stops return them to the center, overcoming the centrifugal force of inertia. Then the cycle repeats.

From" The amount of overtaking of satellites 5 by eccentrics 4 will depend on the difference in the speed of rotation between the flywheel and the central gear 2.

Diametrically oppositely located eccentrics rotate in the same "phase", that is, they transmit the moment simultaneously, this determines the balancing of the system / structure /, and every second pair of eccentrics relative to the other would work sequentially, that is, with two pairs of eccentrics, the moment is transmitted after 180", with three "" pairs through 1207, etc. The sequence of torque transmission by eccentrics significantly improves the characteristics of the variator. o Thanks to the semi-free location of the eccentrics, we received a single-signal rotational y" 20 moment transmission from the drive shaft to the driven shaft without the use of an overrunning clutch, as well as a significant improvement in the torque transmission schedule due to sequential operation of pairs of eccentrics. These conclusions are confirmed on the experimental working model. Thus, the variator allows changing the speed of rotation of the driven shaft from zero to the speed of the driving shaft, while this change occurs automatically and with the corresponding variation of the torque.
