REVERSE-STEERING DEVICE OF WATER-MOTOR ENGINE.

The utility model relates to shipbuilding, in particular to steering devices of high-speed boats, providing control and reverse movement of the vessel.

Known reverse steering of a water-jet .iU a vehicle, comprising a water-jet propulsion, a nozzle, a reverse gear mounted on it and a control system, the nozzle being made rotatable around a vertical axis (see the description of the invention to RF patent No. 2156206, В63Н25 / 46, 09/20/2000).

The described device has a complex structure and requires two separate controls to control the rotation and reverse.

A reversing-steering device of a water-jet propulsion device, mainly a speed boat, is known, comprising a housing fixed to the nozzle of the water jet, with drainage channels mounted on the axles of the steering feather and a reversing damper with a steering feather control mechanism (see A. Bratishko, S. Kalinin S. A. About a water cannon with scapular preload, railway boats and yachts, No. 5 (75) -1978, p. 53-55, Fig. 2).

In the known device, the control of rotation and reverse is carried out by one control element - the steering wheel. This device has drawbacks in terms of boat safety, namely: in the event of a sudden failure due to corrosion of the spring holding the reversing deflector in the upper position, it will sharply lower to the lower position, which will actually cause the reverse to turn on fully in advance of the boat and abruptly stop boats that; in turn will cause injury to passengers;

FLATS OF THE BOAT i.e. reverse forward sudden unauthorized input into the consequences of JH described above.

The task is to create a reliable and simple in design reversible steering device of a water-jet propulsion device.

The task is achieved by the fact that in the reversing steering device of the water-jet propulsion device containing mounted / mounted on the nozzle of the water jet nozzle with drainage channels mounted. on it, on the axes, a steering pen and a compensating flap with a control mechanism for them, a pulley kinematically connected to the steering wheel is mounted on the axis of the pen, while the pulley is provided with a spike connected by a rod and a lever with a compensating damper.

The claimed device is characterized by the presence of the following significant distinguishing features:

a) on the axis of the pen mounted schkvy, kinematically connected with the steering wheel;

b) the pulley is equipped with a spike;

c) the pulley spike is connected to the compensating damper by means of a thrust and a lever.

The use of all the essential features of the claimed device provides a significant simplification of the design — the steering pen and the compensating damper are controlled by one control element — the steering wheel, while minimizing the steering force in any position of the steering pen, as well as eliminating emergency situations, i.e. . increases the reliability of the device and safety.

Studies on patent and scientific and technical literature allowed us to identify a number of technical solutions for a similar purpose, and it was found that signs b and c are absent in them, and sign a is well known.

“2 p. The essence of the claimed is filled with drawings, where $ ig. 1 shows a general view of the reverse-steering device of a water-jet propulsion device; figure 2 is the same, a top view; in Fig. 3, the position of the steering pen and the shutter in forward travel mode; figure 4 is the same, in the move backward mode; figure 5 is the same, in the forward move mode, turn left; figure 6 is the same, in the move backward, turn left. The device comprises a housing 2 with drainage channels 3 mounted on the nozzle I of the water jet 3. On the housing 2, on the axes 4 and 5, respectively, a steering feather 6 and a compensating damper 7 are mounted. On the axis 4 of the feather 6 a pulley 8 is fixed kinematically (using a cable) connected to the steering a wheel (not shown in the devil). The pulley 8 is equipped with a spike 9, connected by a rod 10 and a lever II with a shutter 7. The device operates as follows. When the engine is started (not shown in the diagram), the flow of water from the nozzle I of the water jet with the position of the steering pen 6 and the compensating damper 7 parallel to the boat’s diametrical plane (not shown in the diagram) is directed along arrow A, as a result of which, the ter moves forward. By turning on the reverse gear, the engine speed is reduced and the steering wheel 6 turns the shutter 6 and the shutter 7 c) a position perpendicular to the boat’s diametrical plane and the water flow is directed to the drainage channels 3. In the intermediate position of the shutter b and shutter 7, the boat is rotated to the right or left or forward or backward.
