The invention relates to mechanical engineering and can be used in the transport industry, in particular in the automotive industry, as well as in machine tools.

Known automatic continuously variable inertial transmission, comprising a housing, coaxial driving and driven shafts, drove with radial axes, rotating them independently of each semi-detached two satellites and satellites interlocked with flywheels, placed on one side of the radial axis master and slave Central bevel gear mounted coaxially of the axis of transmission of the Central bevel gear wheel. This wheel was put into engagement with the satellites and through the gears associated with the leading Central conical wheel. The rotation of the flywheel with satellites simultaneously around the axis of the transmission and around the radial axes of the led leads to the inhibition of rotation of the carrier in connection with a permanent change of direction vectors of the moments of momentum of the flywheel relative to the Central point and enables the transfer of torque on the driven shaft (RF patent 2163316, IPC 7 F 16 N 33/14, 3/74, 20.02.2001, bull. No. 5).

The disadvantage of this automatic continuously variable inertial transmission is no recoverable decrease in the counter-rotation of the carrier with the increase in the speed in which demogo shaft, due to the slowdown in atom rotation of all satellites on radial axes were taken.

The closest set of features technical solution to meet the automatic transmission is a continuously variable mechanical transmission containing the input and output shafts mounted on these shafts master and slave Central bevel gear mounted for rotation around the axis of the transmission carrier with radial axes which are rotatably mounted symmetrically to the axis of the transmitting satellites - major and minor. The main satellites made in the form of semi-detached two bevel gears (internal and external) about the axis of the transmission, introduced in engagement with the different Central conical wheels and components with them a pair of bevel gear wheels having different sizes of gear ratio. With the chassis transmission is rigidly connected to a toothed conical Central stationary support wheel, entered into engagement with the auxiliary satellites. Master and slave Central toothed wheels placed on one side of the radial axis was taken, and blocks the main satellites and auxiliary satellites placed on radial axes were taken with independently from each other in rotation. In the case of transfer in PL is skoti, combined with the axis of the transmission, posted by a supporting shaft on which is fixed a gear wheel, put in mesh with two gears, one of which is fixed to the input shaft and a second wheel mounted on the hollow intermediate shaft which is mounted coaxially with the input shaft and fixed toothed conical Central movable support wheel which engages with posted on radial axes drove more satellites, while ensuring the rotation of the input shaft and intermediate shaft in opposite directions (RF patent 2171931, IPC 7 F 16 N 33/14 3/74, 10.08.2001, bull. No. 22).

The disadvantage of this automatic continuously variable mechanical transmission is that the carrier and movable support wheel rotating in one direction, which reduces the frequency of rotation of the main satellites and other satellites. When the maximum rotational speed of the output shaft when the carrier is stationary, additional satellites do not rotate due to engagement with the stationary support wheel. These both circumstances lead to a decrease in counter-rotation was taken as increasing the frequency of rotation of the driven wheel and the driven shaft, which reduces the efficiency of the transfer.

The present invention provides a more intensive protiva the op perate the rotation of the carrier in all operating modes of the transmission, that increases the reliability of the power connection of the input shaft with the output shaft with the transformation of this magnitude of transmitted torque and the rotational speed of the output shaft depending on attached to this shaft load.

This technical result is achieved by the fact that the automatic continuously variable mechanical transmission includes coaxial input and output shafts mounted on these shafts Central bevel gear master and slave wheel mounted rotatably around the axis line of the transmission carrier with radial axes which are rotatably mounted is made of conical gear wheels satellites - primary, secondary and auxiliary.

Master and slave wheels placed on one side of the radial axis was taken. Auxiliary satellite is put into engagement with the Central bevel gear auxiliary support wheel. Additional satellite is put into engagement with the Central bevel gear additional support wheel mounted on coaxial the ohms to the input shaft flooring additional intermediate shaft, which is connected with the input shaft via the drive specified additional supporting wheels, consisting of cylindrical gear wheels and a supporting shaft, accommodated in the housing of the transmission parallel to the input shaft, with specified additional intermediate shaft is rotatably relative to the input shaft. All satellites - primary, secondary and auxiliary posted on radial axes were taken with ability independent from each rotation.

The mutual position of the above transmission elements provides the possibility of rotation of the carrier with its radial axis around the axis of transmission in the opposite direction compared to the additional and auxiliary wheels.

The satellites are made with massive rims and simultaneously with the transmission of torques and rotational movements also perform the functions of the flywheel.

The transfer contains a coaxial input 1 and output 2 shafts mounted on these shafts Central bevel gear leading 3 and slave 4 wheels mounted rotatably around the axis line o-O of the transmission carrier 5 with the radial axis, which is rotatably installed made of bevel gears satellites - primary 6, 7, an additional 8 and 9 auxiliary. The main satellite is made in the form of semi-detached two wheel - inner 6 and outer 7 relative to the axis line o-O of the transmission, introduced in the mesh separately reffering to the current 3 and slave 4 wheels and components with them a pair of wheels, define the specified gear ratio. The leading 3 and slave 4 wheels placed on one side of the radial axis was taken. Auxiliary satellite 9 is introduced into engagement with the Central bevel gear auxiliary support wheel 10. Additional 8 satellite was put into engagement with the Central bevel gear additional support wheel 11 mounted on coaxial to the input shaft 1 flooring additional intermediate shaft 12, which is connected with the input shaft via the drive specified additional supporting wheels, consisting of cylindrical gear wheels and a supporting shaft 13, are accommodated in the housing 14 parallel transmission input shaft. While specified additional intermediate shaft 12 is rotatably relative to the input shaft 1. All the satellites of the main 6, 7, an additional 8 and 9 auxiliary posted on radial axes of the carrier 5 with the possibility of independent from each other rotation. Auxiliary support wheel 10 mounted on coaxial to the output shaft 2 floors supporting the intermediate shaft 15, which is connected with the output shaft using the drive specified auxiliary supporting wheels 10, consisting of cylindrical gear wheels and a supporting shaft 16, are accommodated in the housing 14 parallel transmission output shaft. Two wheels 17, 18 et the th actuator is fixed on shaft 16 and is introduced into the mesh separately with wheels 19, 20, mounted respectively on the output shaft 2 and the auxiliary intermediate shaft 15 with the formation of pairs of wheels, and these pairs of wheels have a common ratio, providing rotatably supporting the intermediate shaft with an auxiliary wheel 10 with greater frequency compared with the output shaft and a driven wheel 4 and in the same direction of development. Drive additional supporting wheels 11 are executed similarly to the above-mentioned auxiliary drive wheels 19, but with the appropriate wheels 21, 22, mounted on the input shaft 1 and an additional intermediate shaft 12 to provide additional rotation of the intermediate shaft with additional support wheel 11 with greater frequency in comparison with the input shaft 1 and the sprocket wheel 3 and in the same direction of development. The mutual position of the above transmission elements provides the possibility of rotation of the carrier 5 with its radial axis around the axis line o-O of the transfer in the opposite direction compared to the additional 11 and 10 auxiliary wheels.

Satellites 6, 7, 8, 9 are made with massive rims and simultaneously with the transmission of torques and rotational movements, perform the functions of the flywheel.

Axis line o-O transmission line radial axes O1-O1drove 5 cross is the Central point Of 1.

As a special case execution, transmission contains one main 6, 7, an additional 8 and 9 auxiliary satellite to the location of their total center of mass on the axis line o-O of the transfer.

As a special case execution, transmission contains two basic 6, 7, an additional 8 and 9 auxiliary satellites, each of which is placed symmetrically to the axis line o-O of the transmission on the respective radial axes of the carrier 5.

As a special case execution, transmission contains two placed on one diametrical line Of1-O1the radial axis of the carrier 5, on each of which independently from each other, the rotation is placed in the possible different combinations of the main 6, 7, an additional 8 and 9 auxiliary satellites.

As a special case of a run, drove 5 contains two pairs of perpendicular between the radial axes and each of these pairs of radial axes placed independently from each other, rotation, respectively, the main 6, 7 or more 8 or 9 auxiliary satellites in different combinations.

The input and output shafts of the transmission are connected by a free-wheeling mechanism 23, the leading element of which is connected with the output shaft 2 and a driven element with the input shaft 1.

The transfer works as follows.

During the rotation of the input shaft 1 with the driving wheel 3 and the stationary output shaft 2 to the driven wheel 4 in connection with the attached to the output shaft of the load or the beginning of the rotation from a stationary position, drive wheel causes the rotation is on the engagement of the inner wheel 6 of the main satellite and interlocked with him outside rear wheel 7 of the main satellite, which rolls on a fixed slave wheel and engages drove 5 with its radial axes in rotation around the axis line o-O of the transfer in the opposite direction to the rotation of the drive wheel 3. When the rotation of the carrier 5 is placed on its radial axes additional 8 and 9 auxiliary satellites roll by being with them in engagement, respectively, and an additional 11 10 auxiliary supporting wheels. Auxiliary support wheel 10 when it is stationary, since it is their drive with a fixed output shaft 2. In this regard, the rotational speed of the auxiliary satellite 9 on the radial axis of the carrier 5 will depend on when this mode works only on the frequency of rotation of the carrier around the axis line o-O of the transfer.

Additional support wheel 11 in all modes of transmission will rotate with greater frequency in comparison with the input shaft 1 and the sprocket wheel 3 in the opposite direction compared with the rotation of the carrier 5. In this regard, which is in mesh with an additional support wheel additional 8 satellite will rotate on the radial axis of the led in this mode the maximum is Noah frequency.

Simultaneous rotation of all of the satellites 6, 7, 8, 9, performs the function of a massive flywheel, around two intersecting axes lines Of transmission and About1-O1the radial axes of the carrier 5 is equivalent to their rotation with respect to the Central point O1the intersection of these lines to the axes. It is known that the rotating body has a certain angular momentum, which is manifested with the observance of fundamental physical law of conservation, according to which the angular momentum can only be changed under the action 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 rotation of the satellites with respect to the Central point 01the vectors of their moments of momentum constantly change their direction. Actions on vectors reflect the appropriate actions on vector quantities (see “technical dictionary” edited Awesonme, second edition, ed. “Soviet encyclopedia”, Moscow - 1980, page 73/1).

From this it follows that the manifestation of the law of conservation of angular momentum in relation to all massive satellites counteracts the rotation of the carrier 5 around the axis line o-O of the transfer. In this regard, the carrier and its radial axis is the backbone DL the transmission of torque from the drive wheel 3 through the power wheels 6, 7 main satellites to the follower wheel 4 and further to the output shaft 2.

As described above, with a stationary output shaft 2 all satellites 6, 7, 8, 9 perform the rotation about the center point O1including additional satellite 8 and the main satellite 6, 7 with the maximum frequency. Consequently, the amount of counter-rotation of the carrier 5 around the axis line o-O of the transfer will also be the maximum that will ensure that the condition of the transmission output shaft maximum value of torque, which depends from the total gear ratio in the gearing of the two pairs of wheels is a drive wheel 3, the inner wheel 6 of the main satellite and the outer wheel 7 of the main satellite, the driven wheel 4. This permits the operation of the engine when stationary output shaft.

External supports to counteract the rotation of the carrier and ensure the transmission of torque with a certain value from the input shaft to the output shaft are eventually installed in the transmission case 14 of the supporting shafts 13 and 16 additional drives 11 and 10 auxiliary support wheels, which determine the nature of the layout of all elements of the transmission and the possibility of their operation to achieve the objectives of the invention. The determining factor is what is the magnitude of the torque in the transmission can be changed only in the presence of external support, not coincide with the axis line of transmission that is provided in this case by applying the supporting shafts 13 and 16.

Under the action of the maximum magnitude of the torque applied to the output shaft 2, it starts to rotate in the same direction as the input shaft 1. This slows down the rotation of the carrier 5 around the axis line o-O of the transfer with simultaneous slowing of the rotation of the main 6, 7, and additional 8 satellites on the radial axes of the carrier 5, and therefore reducing the frequency of rotation of these satellites with respect to the Central point O1. Therefore, increasing the frequency of rotation of the output shaft 2 of the main and additional satellites to ensure the transmission of torque is also reduced to the same extent. This ensures that the automaticity converting the transmitted torque depending on the load on the output shaft.

However, increasing the frequency of rotation of the output shaft 2 speed auxiliary satellites to the radial axis of the led increases. This is because the auxiliary drive wheels 10 provides its rotation with greater frequency compared with the frequency of rotation of the driven wheel 4 and output shaft 2 around the axis line o-O of the transfer. It also promotes the rotation vspomogateljno the supporting wheels 10 and drove 5 with its radial axes in mutually opposite directions.

When the maximum rotational speed of the driven wheel 4 and output shaft 2 took 5 still. However, while it includes a braking torque transmitting torque to the slave wheel. This is because additional 8 and 9 auxiliary satellites revolve on the radial axes of the carrier 5 in all modes of transmission, including auxiliary satellite 9 with a stationary drive rod rotates on its axis with the maximum frequency.

The stability of the carrier 5 in a stationary position and its counter-rotate around the axis line o-O of the transmission is ensured by the fact that even small it turns there is a change of direction vectors of the moments of momentum of the primary, secondary and auxiliary satellites with the manifestation of the law of conservation of angular momentum.

The advantage of the described transmission over the known automatic continuously variable mechanical transmission is that as you increase the frequency of rotation of the output shaft 2 speed auxiliary satellite 9 on the radial axis of the carrier 5 and with respect to the Central point O1also increases, which increases the reliability and efficiency of transmission for converting the transmitted torque and the rotational speed of the output shaft is depending on the applied load.

Technical transmission characteristics are determined by the ratios of all pairs of gear wheels that are included in its composition, and mass of all satellites and relationships between satellites in the size of these masses, performing the functions of the flywheel and inertial loads.

The nature of the work transfer in the presence in its composition of two radial axes drove 5 or two pairs of perpendicular between the radial axes of the carrier and with different number of satellites on these axes will be the same.

If you want to transfer torque and rotation from the output shaft 2 to the input shaft 1 for braking of the working machine, the engine stops. Under the influence of rotating the output shaft is the closure of the free-wheeling mechanism 23 that transfers rotation of the input shaft and further to the engine providing the counter-rotation of the output shaft. It also provides the ability to start the engine by towing the working machine.
