FIELD: engines and pumps.

SUBSTANCE: invention relates to motor industry. The rpm controller represents a device incorporating a planetary differential gear with driving spider (2) and two various-diameter gear wheels (5, 12). Central gear wheel (5) runs opposite to the running spider (2) to transmit engine power to output shaft (6) via the reduction gear that changes the direction of rotation. Central gear wheel (12) runs in the same direction with spider (2) to transmit rotary motion to output shaft (6) via friction clutch (13). Adjusting actuator with a controlled signal, a function of the engine shaft rpm, varies the rotary motion transmission ratio and allows accelerating or decelerating output shaft (6) along with changing the transmission ratio from its maximum to zero.

The invention relates to the field of transport engineering. Its application can be implemented to stabilize the engine speed of the vehicle when it is driven at various speeds and at various ratios of required and available capacity with automatic change gear ratio of the transmission.

There are various ways to control speed on vehicles and approval of gear ratio in the transmission of motion from the motor to the actuator. The most common way is the gear reducer. On vehicles for the coordination of the engine speed and output shaft apply different speed and stepless gearbox. Stepless gearbox is described, for example, in the journal "Automotive industry" №5 for 1983 on p.36-39. Known design stepless gearbox speeds: design "VARIOMATIC" steel belt "transmatic", described in the journal "Automotive industry" №4 for 1983. The lack of gear boxes speed is that when using the gear ratio of the transmission is constant, the engine speed on most modes are not optimal. This impairs the efficiency, increase the load on the engine and the elements of the s transmission. For speed control using mechanical, Electromechanical, electronic speed regulators. Regulators turns with the dosing fuel is described, for example, in patents for inventions: SU 1474307 A1, 23.04.1989. EN 2142567 C1, 10.12.1999. DE 3344585 A1, 13.06.1985. DE 3437324 A1, 10.10.1984. They regulate the speed without changing the gear ratio of the transmission that affects the acceleration of the vehicle.

The objective of the invention is the implementation of automatic control of engine speed, the implementation of its work at an optimal speed, the change gear ratio of the transmission on the transient conditions that are changed by changing the speed of rotation of the output shaft.

This goal is achieved by the fact that according to the invention as a speed controller of a motor vehicle using a device containing a planetary differential with leading planet carrier and two different diameter Central toothed wheels, one of which when rotating drove toward it rotates in the opposite direction and transmits engine power to the output shaft through a gearbox that changes the direction of rotation performed by any known method, and the latter rotates in the same direction as the carrier and transmits the rotation to the output shaft through a friction clutch, which lays the screen separates torque shoulders differential in proportion to the ratio the diameters of the Central wheels and satellites with a variable in it the force of friction, necessary for its rotation regulating actuator, the principle of which may be selected by any of the known schemes, such as centrifugal or electronic, and the controlled signal which is a function of revolutions of the motor shaft, which in turn changes the ratio of torque transmission through the gears of the differential and rotation of the entire mechanism and, accordingly, the acceleration or deceleration of the output shaft of the change gear ratio of the maximum value defined by the difference of the diameters of the Central wheels and satellites differential, when the rotation transmission occurs only through the gears of the differential, up to units, when the slippage in the friction clutch is not, and the whole mechanism rotates as a whole, from the motor shaft to the output shaft, at constant engine speed.

The invention is illustrated in the drawing, which shows schematically the planetary differential transmission of rotation to the output shaft and the friction clutch. According to the invention the rotation from the drive shaft 1 is transmitted to the carrier 2 with the housing. On the drive rod has a pair of satellites 3 and 4, rigidly connected to each other, the axis of which rotates freely on the driver. Satellite 3 rolls on the Central toothed wheel 5 which is free to rotate on the output shaft 6, but is rigidly associated with C is batim wheel 7, which transmits rotation to the gear wheel 8, the axis of which is located on the body were taken and on which is a gear wheel 9, rigidly connected with the toothed wheel 8. A gear wheel 9 through a gear wheel 10, the axis of which is located on the chassis carrier, transmits rotation to the gear wheel 11, rigidly connected with the output shaft 6. The satellite 4 rolls on the Central wheel 12 which is free to rotate on the output shaft and rigidly connected with the leading disk friction clutch 13. The clutch disc friction clutch 14 is rigidly connected with the output shaft 6. During acceleration in the beginning of the movement ratio is greater, the smaller the difference between the diameters of the Central gears and satellites. At the end of the acceleration slippage in the friction clutch no, the whole mechanism rotates as a whole, and its final drive ratio is equal to unity. When increasing the required capacity or reducing engine power when the tendency to fall in turnover, due to the decrease of the friction force regulating actuator (not shown)that is controlled by a signal which is a function of the speed of the shaft 1, decreases the force compressing the friction discs of the clutch and there is slippage in the friction clutch, gear ratio is increased to the desired value, the power number is I, to the extent possible, regulation, and the engine recovers. When reducing the required power or increase power of the engine will have a tendency to increase speed, at the same time control the actuator compresses the discs of the friction clutch stronger and reduces the possibility of friction clutches to slip. This leads to the reduction gear ratio of the transmission and recovery of the engine speed. Regulating the actuation can be performed by any known method, for example, mechanical, centrifugal, hydraulic, Electromechanical, electronic. Reducer 7, 8, 9, 10, 11, changing the direction of rotation can also be performed by any known method.

The speed controller of the motor vehicle Converter gear ratio of the transmission, regardless of the load on the output shaft, wherein as the speed controller of motor vehicle use device containing a planetary differential with leading planet carrier and two different diameter Central toothed wheels, one of which when rotating drove toward it rotates in the opposite direction and transmits engine power to the output shaft through a gearbox that changes the direction of rotation made any the m of known methods, and the second rotates in the same direction as the carrier, and transmits the rotation to the output shaft through a friction clutch, which distributes torque to the arms of the differential in proportion to the ratio of the diameters of the Central wheels and satellites, with the variable in it the force of friction necessary for its rotation regulating actuator, the principle of which may be selected by any of the known schemes, such as centrifugal or electronic, and the controlled signal which is a function of revolutions of the motor shaft, which in turn changes the ratio of torque transmission through the gears of the differential and rotation of the entire mechanism and, consequently, to the acceleration or deceleration of the output shaft of the change gear ratio of the maximum value defined by the difference of the diameters of the Central wheels and satellites differential, when the rotation transmission occurs only through the gears of the differential, up to units, when the slippage in the friction clutch is not and the whole mechanism rotates as a unit from the motor shaft to the output shaft at constant engine speed.
