The invention relates to the field of transport engineering and for the design stage planetary gearbox, which can be used in automatic transmissions, managed with the help of electronic unit and hydraulics and intended for vehicles.

Torque and rotational speed of the engine is converted transmission in accordance with changes in the driving conditions of the vehicle to ensure the vehicle is moving both forward and backward.

The composition of the powertrain includes a transmission of the planetary type, providing the change of torque on the propulsion and speed. Transmission of the planetary type consists of planetary gear sets and friction controls. The planetary series consists of a sun gear which is in constant mesh with gears, which are called satellites, drove defined therein satellites, which can rotate about their axes and the crown gear which is in constant engagement with satellites. There are planetary mechanisms of the first and second class. Planetary mechanisms of the first class have a positive internal gear (when the driver stopped the sun gear and the crown gear is rotated in one hundred the ONU). This sun gear is in constant mesh with the satellite, which is in mesh with another satellite, located on the axis in the driver, which in turn is in mesh with a crown gear. The planetary gears of the second class have a negative internal gear (when the driver stopped the sun gear and the crown gear rotate in opposite directions). This sun gear is in constant mesh with the satellite, which, in turn, is in mesh with a crown gear.

The transmission also includes a friction controls that its purpose can be divided into two groups: brakes and clutches. A friction clutch connecting the elements of the planetary mechanism between them. Friction brakes combine elements of the planetary mechanism with the transmission case.

Part of the transmission may include a hydrodynamic torque Converter (torque Converter), in which the kinetic energy of the working fluid is used to transfer torque from the engine crankshaft to the input element of the gearbox with the ability to increase the torque.

If the hydrodynamic torque Converter (torque Converter) not used, then g is the solution of torsional vibrations, the resulting non-uniformity of rotation of the engine, between the engine and transmission installed the torsional vibration damper (damper).

The use of gear boxes, planetary type, in automatic transmissions of vehicles due to the possibility of obtaining a small-sized compact layout design, easy to fit in the limited dimensions of the body space.

Currently, planetary gearbox, used vehicles and providing seven to nine speeds forward and one back, include three planetary series, and from seven to nine controls. However, such schemes do not implement dynamic performance requirements for vehicles, reduce the kinematic capabilities of the gearbox, due to the complexity of the rational selection of gear ratios rows and transmission, have low efficiency. To improve the dynamic characteristics of the developers involved in the design and manufacture of automatic transmissions, use the fourth planetary line, which complicates the design of transmission, or increase the number of degrees of freedom. This leads to increased friction controls that are required is to enable transmission, that, in turn, leads to the complication of the control system.

Achievable technical result consists in the extension of the kinematic capabilities of the gearbox, increase its durability, and also allows you to greatly expand the number of types of vehicles, which can accommodate the transmission of such kinematic scheme. Obtaining a large value of gear ratio in first gear compared to the gear ratio is receiving at the second forward gear will allow you to refuse the use of the hydrodynamic torque Converter (torque Converter) and use only the torsional vibration. This will reduce the number of parts, dimensions gearbox and reduction of its weight.
