The invention relates to mechanical engineering and can be used as a continuously variable transmission of a vehicle, such as transport robot controlled remotely.

Known inertial impulse transmission comprising a drive shaft with a pulse mechanism, an intermediate shaft with two mechanisms of free running (USDA), pressurized and weekends, and the driven shaft with the flywheel (see Aeiou. Inertial auto transformers torque. M., engineering, 1978, p.11-13).

The disadvantage of this transmission is the presence of two mechanisms of free running. In this case, the process of transmission of torque is effected in the following sequence. The action of the momentum is sinusoidal in nature, in the phase of 0<φ<π it has a positive sign in the phase π≤φ≤2π - negative. The function of the corps of the Ministry of agriculture is cutting off the negative momentum by stopping the intermediate shaft, and in the phase of the positive pulse output of the USDA connects the intermediate shaft to the output, transmitting a positive pulse on the output shaft. Job corps USDA paired with extremely high dynamic loads associated with an abrupt stop of the intermediate shaft at the moment of braking, reverse pulse, occurring with a high frequency of on the.

Known continuously variable mechanical transmission is adopted for the prototype. The transmission consists of a drive shaft with a pulse mechanism, an intermediate shaft with two USDA - pressurized and weekends and the driven shaft with the flywheel (see patent No. 2294468, F16 33/14, publ. 27.02.2007,, bull. No. 6).

The disadvantage of this transmission is required braking intermediate shaft using a corpus MOA at the time of occurrence of the reverse pulse. The abrupt stop of the intermediate shaft, with significant moment of inertia and rotation speed, causes in detail corps of the Ministry of agriculture very high voltage, which is the main factor reducing the reliability of such programs.

The task of the invention is to improve reliability of the transmission as a whole.

The technical result obtained by carrying out the invention, consists in the absence of inhibition of the intermediate shaft when the callback pulse until the occurrence of a positive pulse, which is closed MA output.

This result is achieved by the fact that in continuous mechanical impulse transmission comprising a drive shaft with a pulse mechanism, the intermediate shaft with the output mechanism of a free motion, the driven shaft with the flywheel, what is new is that the transmission is equipped with a control unit, as the output is of echanism freewheel installed clutch remote control with the possibility of including using the control unit, on the intermediate shaft posted speed sensor connected to the control unit.

The proposed solution allows the intermediate shaft to perform an oscillatory movement of the character in accordance with the pulse frequency of the pulse mechanism, but remote automatic switching of the output of the MOA allows you to snap it with the driven shaft only when the rotation in the positive direction. During this start-up as the most severe transmission mode, the circuit may not each time a positive pulse, and after 2 or 3 pulses, which slightly increases the acceleration of the transfer, but significantly reduces the load on MA output.

The invention is illustrated by drawings, where

figure 1 - stepless pulse transmission,

figure 2 - pulse transmission mechanism.

Continuous mechanical impulse transmission comprises a drive shaft 1 with the switching mechanism 2, the intermediate shaft 3 has mounted on the output mechanism 4 free wheel and the driven shaft 5 with the flywheel. On the intermediate shaft 3 posted by the speed sensor 6 connected to the control block 7. As the output of the free-wheeling mechanism installed clutch remote control with the possibility of including using the control block 7. Switching mechanism includes a gear 8 internal gears, u is Chou gear 9 and the satellite 10 with unbalanced loads 11.

The device operates as follows.

During the positive pulse, when the rotation direction of the intermediate shaft 3 also conditionally positive, the control block 7 outputs a signal to enable the output of the free-wheeling mechanism. When the negative pulse (φ≥π) and, therefore, at the time of changing the direction of torque of the intermediate shaft 3 output mechanism 4 free running disabled unit 7 of the control, that is, the shafts 3 and 5 are open, the intermediate shaft 3 starts to rotate in the opposite direction. In the beginning of the rotation shaft 3 in the positive direction, the output mechanism 4 free running again closed by the control block 7. The process is repeated. However, depending on the frequency of change of direction of the intermediate shaft 3 unit 7 management can give the start signal to the output mechanism 4 free running not immediately with the appearance of a positive pulse, and skip a few of these pulses, which reduces the load on the output mechanism 4 free running, although it increases the acceleration pulse transmission. When entering the direct transfer of the load on the mechanism of a free stroke is significantly reduced, since the switching mechanism operates in mode, only the positive pulse, that is, the output mechanism of a free move permanently closed.

Besthope the striated mechanical impulse transmission, consisting of the drive shaft with the switching mechanism, the intermediate shaft with the output mechanism of a free motion, the driven shaft with the flywheel, wherein the transmission is supplied by the control unit, as the output of the free-wheeling mechanism installed clutch remote control with the possibility of including using the control unit, on the intermediate shaft posted speed sensor connected to the control unit.
