The invention relates to shipbuilding, and more particularly to outboard propulsion and steering complexes (DRC), mainly for boats used in shallow water and transported by land.Closest to the proposed technical solution is the propulsion and steering the ship used in shallow water and the transport screw in the nozzle, connected to the hull through suspension drive rotation of the column and the drive of the propeller, this pendant is made in the form of a closed planar three-tier mechanism formed by two arms and a hydraulic cylinder connected to the hinge.However, the known DRC cannot be effectively used as propulsion in conditions of shallow water, especially on boats with variable draft, for example, on motor component of the transportable vessel or floating bridge, as in the connection node of the column with the suspension and the suspension missing transverse and longitudinal protect speakers from damage during grazing (impact) column of a foreign object or dirt from the effort exceeds the value of the engine thrust.The invention is intended to improve the reliability of the DRC during the operation of the craft in conditions of shallow, weedy waters.The technical result is achieved by the fact that in the DRC with characteristics closest analogue, swing-hinged column is equipped with a replaceable shear safety pins installed in the node swivel column with suspension and at the top of the deadlift charms for protection from peevyhouse the amount of emphasis of the propeller.The technical result is also achieved by the fact that in the upper traction suspension removable shear safety pins mounted in bushings in pairs and placed in the oval hole of the movable slats of the rod and are separated by a jumper bar and top link suspension is equipped with an adjustable mortgage emphasis, temporarily locking rod in its position at the cutting safety pin, and is equipped with a hydraulic shock absorbers, protecting from cutting the second guide pin during the return swing of the hinged column into position after cutting the first safety pin and pivoting column.To achieve a technical result, each of the hydraulic shock absorbers can be made in the form of a cylinder, provided with two cavities, a by-pass channel walls with calibrated holes in each cavity and a piston rod having an enlarged diameter bands, which interact with calibrated holes of the walls of the cylinder during the return of the piston rod to the initial operating position after removing the safety pin and overcoming obstacles form the perimeter of the narrow slit-dropage DRC in the working position, side view of Fig. 2 - the same, the section a-a in Fig. 1; Fig. 3 - this is the same cross-section B-B in Fig. 2; Fig. 4 - the same, the section b-b In Fig. 3; Fig. 5 - the same, type G in Fig. 1; Fig. 6 is the same, the section G-G in Fig. 5; Fig. 7 is the same, the node I in Fig. 6; Fig. 8 - this is the same site II in Fig. 5; Fig. 9 - same-section d-D in Fig. 1.Propulsion and steering complex (DRC) boats made in the form of a rotary folding speakers, including upper angular gear 1, the lower angular gear 2, the screw 3 in the guide nozzle 4, the suspension in the form of a parallelogram connecting the column with the hull boats 5, consisting of parallel spaced between an upper thrust 6, lower links 7, cylinder cavities 8, the drive of the propeller 9, the drive rotation of the lower angular gear with the propeller screw in the guide nozzle 10 around the vertical axis 11 and the actuator pivoting column 12.The upper and lower links charms reinforced hinged in the housing top gear 13 and the housing of the servomotor turning 14 in parallel between a horizontal axis 15, 16, 17 and 18.Swing-hinged column is protected from damage due to grazing (impact) column of a foreign object or the bottom of the reservoir onena in the form of a replaceable shear safety pins 19 and 20, installed in the top two sleeves 21, fortified in the oval holes 22 of the movable pull strap 23 and separated by a jumper thrust 24 and two lower bushings 25, fortified in the guide plate 26. Top link suspension also includes two cylinder 27, the two piston rod 28 with the lugs 29 interconnected by a transverse beam 30, which pin 31 is connected with a movable pull strap 23.In the area of the installation adjacent shear safety pins on the horizontal axis 32 reinforced swivel fitting lugs 33, which, after cutting the safety pin are inserted into the gap 34 between the movable plate 23 and thrust of the guide 26 and fix the upper arm in position to replace the cut of the safety pin on the new (from the zip). The rod 28 is in the cylinder 27, is in the middle of the piston 35, the sealing rubber ring 36, and the edges - thickening 37, which together with the tab 38 in the cylinder 27 and the guide 39 in the sleeve 40 is formed along the perimeter of the narrow slits in the choke 41, which prevents the cutting of the second safety pin at the back of the column into position after cutting the first safety pin.The cavity of the cylinder 27 to a certain level-drenched working what channel is the upper tank 44 large holes 45.The upper angular gear and column are generally able to be rotated around a horizontal axis 46 tripping (impact) column of a foreign object or the substrate in a perpendicular direction.From the inadvertent rotation around a horizontal axis 46 of the upper angular gear is held two Cams 47, which are propped up by the Belleville springs 48 and abuts the inclined plane 49 of the projections of the housing of the suspension 50. The Cams 47 are placed in the holes 51 PrimaryKey 52 upper angular gear arranged symmetrically about the horizontal axis 46.Turn the Cams 47 are held by bolts 53. Each of the Cam 47 has a locking mechanism between the end 54 of the rod 55 and the end 56 of the rod 57 on the guide surfaces 58 of the rail 59 is selected 60. Rake 59 spring built into the inside of the housing upper angular gear and the roller 62 all the time pressed against the disk-fist 63. When the roller 62 of Reiki lies in a hollow disk-Cam 63, the box 60 is located on an axis between the ends of the rod 55 and the rod 57. The rod 57 is prevented from moving axis 64, which is connected to the frame using shear predohranitelya in an inclined plane 49 of the housing upper angular gear. In this position, the Cam 47 is locked, and it keeps the focus of the propeller. When the roller 62 of the rail 59 is pressed by the protrusion of the disc Cam 63, box 60 moves away from the center axis of the rod and the rod, the gap between them becomes empty and the Cam 47 may be bonded to the inside of the holes 51 PrimaryKey 52 and out of engagement with the inclined plane 49. In this position, the Cam 47 is not locked. The disk Cam 63 has a special profile. When turning the column transversely of its longitudinal axis 46 of one of the Cam 47 is in the locked position and holds the power of focus from the propeller 3 and the other Cam 47 is in an unlocked state. When the column is rotated forward" or "back", i.e., along the longitudinal axis 46, both the Cam 47 are in a locked state. This ensures retention of the columns in the working position from the focus of the propeller and the possibility of its turning from forces arising from the opposite fence side when hitting an obstacle - a foreign object or the ground. After overcoming obstacles under the action stops and the weight of the column is rotated back into position.In the case of an application on the Cam 47 forces more calculated to avoid damage to the speakers in the mechanism of cross-protection provided dresnok way.After the descent of the craft to the water propulsion and steering system using an actuator pivoting 12 is put in the operating position (Fig. 1).The required depth of the nozzle 4 with the rowing screw 3 is provided with the help of hydraulic structures 8 which, when the extension rod increases the depth, when the retraction of the rod - reduces the depth.The rotation of the propeller 3 is performed from the transmission of the motor 66 through the drive of the propeller 9 (Fig. 9), the upper angular gear 1 and the lower angular gear 2.During the course of the craft 5 "forward" (Fig. 1) propeller 3 nozzle 4 create emphasis in direction 67, while the upper rod 6 works on stretching and fixed in this position the safety pin 19, the force cutoff more emphasis of the propeller 3. When the blow nozzles or propeller on a foreign object (stone, timber or grazing on the ground they will act impact force 68, which may be significantly (many times) to exceed the value of the stop 67 of the propeller. To propulsion and steering complex is not destroyed, at the moment of impact is triggered longitudinal protection is as follows.The upper angular gear 1 with a nozzle 4 and a propeller in which the rod 28 is moved in the direction of the cylinder 27. Yoke 30 through the pin 31 moves the sliding bar 23, which moves the sleeve 21 and will be cutting a removable safety pin 20. The movement of rod 28 oil piston 35 is pushed from one cavity 43 of the cylinder in the other cavity 42 through the large openings 45 and the bypass channel 44 that without obstacles allows you to quickly fold down the column. After overcoming the obstacle (stone, timber and others) under the action of the stop of the propeller and the weight of the column rods 28, the lugs 29 and the yoke 30 is returned to the initial operating position. In order to avoid the kick and slice a removable safety pin 19, which holds the focus of the propeller (the cut was opposite the pin 20) take effect hydraulic dampers: thickening rod 37 is included in the narrowing of the cylinder 39, and pushed the piston 35, the oil is able to flow only through the narrow annular slit-orifice 41, a large hydraulic resistance in the initial position, the rod 28 is returned with quenched speed.Tripping the column on the obstacle when the "back" longitudinal protection works similarly, when the nozzle 4 with the rowing screw 3 rotates around a horizontal axis 16 against casewatch temporarily to replace a sheared pin restore using the rotary mortgage lugs 33, introduced into the gap 34 between the movable plate 23 and the guide plate 26.The upper angular gear 1 is able to rotate around the longitudinal axis 46, this allows you to turn the entire column around the longitudinal axis 46 when hitting column on underwater obstacle (stone, timber and other) in the direction opposite to the direction of the focus and perpendicular to the longitudinal axis 46. This inclined plane 49 of the lug casing suspension 50, affecting the mating inclined surface of one of the Cams 47, presses it into the hole 51, and the column leans back from the impact of her obstacles. After overcoming obstacles floor action the focus of the propeller and the weight of the column is rotated back into position.In the case when the focus of the propeller operates in one direction, and the vehicle is coasting (for example, when a sudden maneuvering) in the opposite direction, then the Cam 47 may impact strength higher than the calculated one, which is transmitted through the rod 55, box 60 on the rod 57, which cuts off the pin 65, the Cam is pressed into the hole 51, escapes from the surface 49, allowing the column to lean back. After the shear pin 65 of the Cam 47 is held in videolady to replace a broken pin on a new one from the zip. To replace the cut of the pin 47 on a new mechanism of cross-protection is the hub of the arm 71, voracova in which case it is possible to provide the locking Cam 47 and the normal operation of cross-protection, in addition to the cases described in sharp maneuvering the craft.The DRC protection against damage due to shock in the longitudinal and transverse directions substantially increased reliability, virtually eliminating breakage of the column, especially her charms when working in shallow water in the conditions of the clogged area.The health protection and operational reliability of the DRC were confirmed during the preliminary and state tests of prototypes of the boats, equipped with the DRC proposed design, in conditions of shallow water. 1.
