The inner and outer main wheel of the satellites put into engagement with the sprocket wheel fixed on the input shaft, and a driven wheel mounted on the output shaft. Additional satellites are put into engagement with the Central support wheel mounted on the end of the hollow intermediate shaft, is placed coaxially with the input shaft. The intermediate shaft is connected with the input shaft by means of three consecutive siteplease driving wheels, the first of which is fixed to the input shaft, a second wheel on the intermediate shaft and the third wheel is mounted on a support axis and is intermediate between the first and second wheels. The reference axis is placed outside the axis of the transmission.

The disadvantage of this transmission which is used in the composition of the hollow intermediate shaft, placed coaxially with the input shaft, on which are fixed two wheel - supporting wheel and the second drive wheel, which leads to an increase in the size of the transmission in the axial direction with a corresponding increase in mass. Implementation of the main satellites, drive and driven wheels in the form of a conical, not cylindrical wheels, also complicates the transmission device.

The transmission is equipped with a free wheel mechanism 17, one link of which is fixed in the housing 12 of the transmission, and another link connected with the planet carrier 6 with capability of rotation were taken only in the direction of rotation of the driving shaft 1.

Line O1-O1radial axes in the place 6 and the axis line o-O of the transfer intersect at the Central point O 1combined with these axes.

As a special case of execution, the drive wheels 8 contains bevel gears and the axis 11 of the intermediate wheel 10 are accommodated in the housing 12 of the transmission parallel to the axis line O-O of the transmission, while gearing 15, located on the surface of the disc supporting wheels 8 and brought into engagement with the intermediate wheel 10 has an internal toothing.

As a special case of a run, drove 6 placed on the drive shaft 1 (see figure 1), with the possibility of rotation relative to it, the slave Central wheel 4 is made with an internal gearing, and gear ratio between the lead 3 and slave 4 Central wheels enables rotation of the leading Central wheel with an angular velocity compared to the slave Central wheel with a stationary drive rod 6.

As a special case of a run, drove 6 is placed on a driven shaft 2 with the possibility of independent rotation from him, leading the Central wheel is made with 3 inner mesh, and the gear ratio between the master and the slave 4 Central wheels enables rotation of the slave Central wheel with an angular velocity compared to the leading Central wheel with a stationary drive rod 6 (see figure 2).

Automatic continuously variable mechanical transmission works as follows.

During the rotation of the driving shaft 1 with the leading Central wheel 3 and the stationary driven shaft 2 due to the applied load or the beginning of the rotation from a stationary position rotates the main satellites 5, because they are in engagement with the rotating leading Central wheel 3. Rotating the main satellites rolling on a fixed slave Central wheel 4 and involve drove 6 with its radial axes in rotation around the axis line O-O of the transfer in the direction of rotation of the driving shaft 1. Together with the planet carrier to rotate around the axis line O-O of the transmission mounted on radial axes drove 6 additional satellites 7, which are in engagement with the supporting wheel 8, which provides simultaneous rotation on the radial axes of the carrier 6.

The drive wheels 8 by means of its constituent gears 9 and 10 transmits constant rotation in all operating modes of the transmission from the driving shaft 1 on the support wheel 8 in the direction, opposite the MD direction of rotation of the drive shaft and the leading Central wheel 3. This drove 6 with its radial axis and the support wheel 8 to rotate around the axis line O-O of the transfer in mutually opposite directions. This provides the additional rotation of 7 satellites simultaneously around the axis line O-O of the transmission and the axis line O1-O1the radial axes of the carrier 6 with the maximum frequency.

Simultaneous rotation of the additional satellites 7 around two intersecting axes - axis line O-O of the transmission and the axis line O1-O1the radial axes of the led 6 is equivalent to their rotation about the center point O1the intersection of these axes. It is known that the rotating body has a certain angular momentum, which is manifested with the observance of universal conservation law, according to which the angular momentum can be changed only under the influence of external forces. It is also known that the angular momentum when rotating the phone about a point is a vector quantity. When the above character rotation additional satellites 7 with respect to the Central point O1the vectors of their moments of momentum constantly change their direction. Actions on vectors reflect the appropriate actions on vector quantities (see, for example, "technical dictionary" edited by academician Awesonme, second edition. Soviet encyclopedia", Moscow - 1980, p.73/1).

From this it follows that the manifestation of the universal law of conservation of angular momentum prevents rotation of the carrier 6 with its radial axis around the axis line O-O of the transfer. In this regard, the carrier and its radial axis are the backbone for transmission of torque from the leading Central wheel 3 through the main satellites 5 to the slave Central wheel 4 and then to the driven shaft 2.

When stationary slave Central wheel 4 speed additional satellites 7 with respect to the Central point O1is the greatest. Therefore, when experimental conditions, the counter-rotation of the carrier 6 around the axis line o-O of the transfer will also be the maximum that will deliver on the stationary slave Central wheel 4 and then to the driven shaft 2 the maximum value of torque. This permits the operation of the engine and the drive shaft 1 together with the leading Central wheel 3 with a stationary driven shaft 2. External support for braking the rotation of the carrier 6 and ensure the transfer and conversion torque is ultimately the housing 12 of the transmission, which has not coincide with the axis line O-O of the transmission axis 11 of the intermediate wheel 10 of the drive wheels 8.

From the above it follows that the value of hormonedependent force, attached to the cage 6, depends on the weight and dimensions additional rotating satellites 7 and the frequency of their rotation with respect to the Central point O1and from gear ratios all included in the transfer of pairs of wheels. This determines the basic transmission parameters.

Under the action of the maximum moment of force applied to the slave Central wheel 4, it begins to rotate in the opposite direction compared with the drive shaft 1. This slows down the rotation of the carrier 6 with its radial axis around the axis line O-O of the transfer with simultaneous slowdown additional satellites around 7 radial axes of the carrier 6 and the Central point O1. Accordingly decreases associated with this braking torque on the carrier and depending on this value of the transmitted torque.

When the maximum rotational speed of the slave Central wheel 4 and the driven shaft 2 took 6 still. However, while it includes a braking torque transmitting torque to the slave Central wheel 4. This is because the support wheel 8 rotates continuously in all modes of transmission, and causes the rotation of the additional satellites 7, including when stationary the driver. The stability of the carrier 6 and its radial axis when data is m mode is provided for those even with their small rotations around the axis line O-O of the transfer is a change of direction vectors of the moments of momentum of extra satellites 7 with respect to the Central point O1with the manifestation of this universal law of conservation of angular momentum.

If you want to transfer torque and rotation from the driven shaft 2 to the driven shaft 1 for inhibiting production machine, the engine stops. Under the influence of rotating the driven shaft 2 is the circuit of the free-wheeling mechanism 17, which provides a flow of power from the rotating shaft to the driving shaft and further to the engine, which provides resistance to rotation of the shaft when the idle mode. It also provides the ability to start the engine by towing the working machine.

Based on the above characteristics of the proposed transfer, mentioned above technical result is achieved by the fact that in the proposed invention in comparison with the approved prototype (patent No. 2171927) no hollow intermediate shaft bearing support wheel and one wheel of the drive wheels, and halved the number of wheels of the main satellites, which together provides a simplification of the device, reduction of the weight and size of the transmission in the axial direction. The Deputy is and the greater part of conical wheels on the cylindrical wheels also contributes to the simplification of the transmission device. However, reduced friction losses in the transmission due to a smaller number included in its composition gears.
