The invention relates to vehicles, particularly for the propulsion of vehicles with high cross.

Known mover (see Afraide. Dictionary - reference mechanisms, p.47-48. "Engineering", Moscow, 1987 - similar). This propeller at the front of the platform is inclined in the direction of motion, has a spring-loaded pendulum with a crank on the end. The location of the crank on the pendulum during its rotation creates oscillations of the pendulum, when it is changing its moment of inertia due to the changing center of gravity. However, the inclined arrangement of the pendulum does not allow directly by the oscillations of the pendulum to move the platform and effectively combine the change of the moment of inertia of the pendulum with the existing forces. Therefore, in a given direction of the sustainable movement, speed, tractive effort is not formed.

These disadvantages are eliminated in the thruster (see patent RU 2288858 C2, IPC B62D 57/00 (2006.01), F03G 3/00 (2006.01) - prototype). The propulsion device includes a platform, a spring pendulum with a busy sector, fluctuations of which is located in the plane of motion. On the platform mover fixed frame, on its racks installed the stops on the pendulum is the pulley with the crank, which is designed for rotation from the pulley. The hammer on the pendulum is mounted for interaction with at least one stop the Pendulum through a spring connected with the frame in the plane of its oscillation, and the axial line of the sector oscillation of the oscillating element is perpendicular to the direction of movement. This mover moving the platform in a given direction is performed directly by the motion of the pendulum when the platform is raised and when the maximum angular velocity of the pendulum, therefore, increases the speed, traction and reduced power consumption on the move. However, in this propulsion traction from the pendulum to the platform is via a spring. This prevents stable and full use of each cycle of oscillation of the pendulum to move the platform propulsion due to the lack of tight coupling between the pendulum and the frame. Possible mismatch of action of horizontal forces that move the platform, and vertical forces, lifting her in these moments. Such mismatch can be, for example, when a sudden change in speed of the drive or with a large tilt of the platform. The result of such mismatches are reduced movement speed, traction and increased energy consumption for moving the mover.

Object of the invention is the reduction of energy consumption on the move, increasing the speed and traction.

The task is achieved by the fact that the propulsion device includes a platform mounted on her frame with sacral is authorized by the axis. The frame is installed vertically on the platform, and installed on the axis of the pendulum and the rotation drive. Sector of oscillation of the pendulum is located in the plane of motion. The rotational drive is connected chain gear with the crank located on the pendulum, and the drive oscillation of the pendulum, made in the form of a crank mechanism. The axis of oscillation of the pendulum is attached to the chassis between the platform and the crank. The relationship of the pendulum to the frame via a crank mechanism allows each cycle of oscillation of the pendulum to be fully utilized for the movement of the platform, and also provides a stable matching moments of action of the horizontal force that moves the platform in a given direction, and vertical force, lifting it and lowering the resistance movement of the propulsion unit on a support surface. Vertical power lifting platform is created by the fact that the axis of oscillation of the pendulum is attached to the chassis between the platform and the crank.

The task is achieved by the fact that the axis of oscillation of the pendulum mounted crank associated with the rotational drive, and chain drive with a crank mechanism and gear with the crank located on the pendulum. This increases the force that moves the mover on the supporting surface, and the vertical force lifting platform propulsion is generated by the cargo, the set is built on a crank mechanism.

The hinge connecting rod with a pendulum made movable on the pendulum, allows a wide range to adjust the speed and traction force inversely proportional.

Figures 1 and 3 shows the schematic of the propulsion that drives the oscillation of the pendulum is made of the crank mechanisms.

The rotation is transmitted chain drives and gear. Figure 2 and 4 shows the simplified scheme. In figures 1, 3 arrows show the direction of rotation of the cranks, the crank mechanism and the direction of movement of the propulsion forward, arrow also shows the main forces acting on all circuits. Figure 5 shows a diagram of a communication node of the pendulum rod through the movable joint.

The propulsion device 1 includes a platform 1, bent at the edges, which is vertically fixed frame 2, made of steel in the form of an oblique line. On the short side of the frame 2 is fixed axis 3 of oscillation of the pendulum 4 with a double asterisk 5, associated with the motor for rotation, the rotation drive not shown. At the other end of the pendulum 4 axis 6 has a crank 7 with the load 8 and the sprocket 9. The pendulum 4 in the middle part through the hinge 10, the connecting rod 11, the axle 12 is connected with a crank mechanism 13 with a sprocket wheel 14, mounted on the axle 15 mounted on the long side of the frame 2. Double 5 star connected with the star, the daughters 9 and 14 circuits 16 and 17 respectively. Parameters all stars are the same. The main force against movement T1, T2, in the direction of motion (T1*, T2*, and the centrifugal force R. Other force applied to the pendulum 4 and to the axis 3, including those associated with the power of T1, are not taken into account and in the drawing figure 1 is not shown. Figure 2 shows the diagram "a" - the extreme right position of the pendulum 4 with the crank 7 with the load 8. Scheme "b" is the average position of the pendulum 4 with the crank 7 load 8 in the course of the pendulum 4 left. In the diagram "C" is the leftmost position of the pendulum 4, the crank 7 load 8.

Figure 3 on the platform 1 with the bent edges of the fixed frame 2, made of steel in the form of a truncated trapezoid. On the long side of the frame 2 is fixed axis 3 of oscillation of the pendulum 4, it has a 5 star associated with the motor for rotation, the rotation drive not shown. Between the platform 1 and axis 3 at the other end of the pendulum 4 is fixed axis 6. On this axis 6 has a crank 7 with the load 8. The pendulum 4 through the axis 6, the connecting rod 9, the axle 10 is connected with a crank mechanism 11, which is made with the load 12, mounted on the axis 13, is fixed on the short side of the frame 2. A crank mechanism 11 through an associated sprocket 14 chain 15, the sprocket 5 is connected with the crank 16 17 cargo mounted on the axis 3. The cranks 7 and 16 provided with teeth forming a gear. Force T3, T4, T5, T6, nab is aulani against movement, and in the direction of movement is directed accordingly force T3*, T4*, T5*, T6* of them T3*, T4*, T6* attached to the frame 2 on the axes 3 and 13, and centrifugal forces P1, P2 and P3. Figure 4 shows the diagram "d" is the rightmost position of the pendulum 4 with the crank 7 and cargo 8, 12, 17. In the diagram "e" is the average position of the pendulum 4 with the crank 7 and cargo 8, 12, 17 during the course of the pendulum 4 left. In the diagram "K" is the leftmost position of the pendulum 4 with the crank 7 and cargo 8, 12, 17. On the crank mechanism 13 figure 1 and 11 3 fixed axis 18 diametral axes, respectively 12 and 10. On the axis 18 can be rearranged rod 11 figure 1 and the connecting rod 9 figure 3.

Works mover in the following way. Set the load 8 of the crank 7 in the upper position when the vertical position of the pendulum 4 and the upper position of the axis 12 of the crank mechanism 13, as shown in figure 1. Turns on the motor for rotation in direction of arrow. Asterisk 5 starts to rotate, and through a chain drive including a chain 16, 17 and sprocket 9, 14, rotates the crank 7 and a crank mechanism 13, through which the hinge 10, the connecting rod 11, the axis 12 results in oscillation of the pendulum 4 together with the crank 7 and the load 8. All cycles of the oscillation are the same, each of them during the course of the pendulum 4 right, passes the position of the 2 far left "C"average Fig 1, and "a" far-right. During the course of the pendulum 4 to the left, on the contrary, the provisions of "a"average in" and zakluchitel the e position of the cycle. When the oscillations of the pendulum 4, the rotation of the crank 7 with the load 8 and the crank mechanism 13 there are the forces T1 and T2 (in the drawings shows a horizontal projection of the main forces)against movement figure 1 and their reactions T1*and T2*, aimed in the direction of travel. Power T1* attached to the frame 2 and through it transmits the force to the platform 1. The horizontal projection of forces in the middle positions of the maximum, because they are equal to their natural values. Power T1*directed forward, significantly exceeds the same force T1 *directed back against the movement. As the cargo 8 of the crank 7 moving forward, figure 1 is located at the top, the moment of inertia of the pendulum 4 at such position of its maximum. During the backward motion, the position "b", figure 2, the load 8 is located at the bottom, the moment of inertia of the pendulum 4 is minimal. The magnitude of the forces T1 and her reaction T1* depend on the resistance to the motion of the pendulum 4, with increasing resistance increases and, conversely, decreases with decreasing. The resistance value of the sum of the resistance created by the moment of inertia, which in this movement of the pendulum 4 to the right of the maximum, and the resistance created by the power of T2*. The magnitude of changes equally, that the left, right, and directed against the movement of the pendulum 4. Vertical projection of the force f in position 1 maximum. With this force power P pripodnimi the t platform 1 through the axis 6, the pendulum 4, the axis 3 and the frame 2, and the power of T1* moves it forward. When the motion of the pendulum 4 in the opposite direction, to the left, position "b", 2 the sum of these resistances is minimal due to the minimum moment of inertia, the force T1* with minimum force acts through the frame 2 on the platform 1 to the right. This action prevents the centrifugal force P, which is the maximum magnitude of the presses platform 1 to the supporting surface and prevents it from moving backward.

In the mover 3 sprocket 5 from the rotational drive torque passes through the circuit 15, the sprocket 14 of the crank mechanism 11, through which the axle 10, the connecting rod 9, the axis 6 creates oscillations of the pendulum 4, and the rotation of the crank 7 is gear. To enable rotation drive cargo mounted on the crank 16 and the crank mechanism 11 at the top and on the crank 7 on the bottom, as shown in figure 1. The cycle of oscillation of the pendulum 4 includes provisions when moving to the right, the far left "to"average figure 3, the extreme right "d" and when moving to the left the opposite position "d", "e", and "K". Force 3 against forward movement T3, T4, T5, and T6, aimed in the direction T3*, T4*, T5*, T6*, of them to the frame 2 of the applied force T3*, T4* T6*, their greatest impact through the frame 2 on the platform 1 is generated in secondary positions figure 3 and figure 4, "e", since the horizontal projection of forces in which Aceh positions equal to their natural values. The moment of inertia of the pendulum 4 in the lower position of the goods 8 3 greater than in the position "e" of figure 4. The total resistance that impedes the motion of the pendulum 4 to the right, increasing the power T3, her reaction T3*, is formed by increasing the moment of inertia of the pendulum 4 and the force T5* against his movement. In this period of the pendulum 4 to the right of the centrifugal forces P1 and P2 are balanced, and the power P3 with a maximum value of the lift platform 1. Power T3* T4 forces* and T6* with a minimum of resistance to move the platform 1 forward. When the motion of the pendulum 4 to the left and passing the middle position "e", 4, total resistance associated with the moment of inertia of the pendulum 4 and the force T5*directed against the motion of the pendulum 4 is minimal due to the minimum moment of inertia. The resistance is low, hence the low amount of force T3*pointing to the right. Centrifugal forces P1 and P2 are directed in different directions, significant steps on the platform 1 does not have. Centrifugal force P3 is facing down, push the platform 1 to the supporting surface and prevents forces T3*, T4*T6* move the platform to the right, back. In the extreme positions "d" and "K" 4 forces directed in opposite directions. Consequently, the resulting movement of the propulsion as in figure 1, figure 3 is a stable moving forward with appreciation the authorized speed, traction and low energy consumption.

At low speed of rotation of the actuator when the friction force platform 1 on the supporting surface exceeds the force that moves the mover, it is not moved.

Changing the direction of movement of the propulsion is carried out or change the direction of rotation of their drives or moving rods 4 on the axis 18 with the axis 12 of figure 1 and with the axis 10 figure 3.

Installation of the rolling hinge 10 instead of the fixed hinge figure 5 connecting the pendulum 4 rod 11, lets move it to thrust 19 on the rod 4 in the direction of the axis 6 to slow the speed of movement of the platform 1 and to increase traction. While moving in the opposite direction the pendulum 4 to the axis 3 on the contrary to increase movement speed and reduce traction. The movable hinge 5 can be mounted on the pendulum 4 figure 3, which if necessary can be extended down to the location of the rolling hinge 10 below the axis 6 in order to widen the range of variation of speed and traction.

The pendulum 4 with the crank 7 may also be located vertically above the crank 16. In this case, the crank mechanism 11 will accordingly be higher, and the short side of the frame 2 extends.

Thus, the execution of the drive oscillation of the pendulum in the form of a crank mechanism and the relationship Pref is Yes rotation with him and with the crank, located on the pendulum, chain drives allow to use each swing of the pendulum to move propulsion, including when tilted his position. The location of the axis of oscillation of the pendulum between the platform and the crank allows you to lift the platform and move it in the direction of movement with minimal resistance.

The location of the crank on an axis of oscillation of the pendulum, its connection with the crank located on the pendulum gear, allows you to increase the forces acting on the mover. The establishment of cargo on a crank mechanism provides movement of the platform mover on the supporting surface in a given direction with minimal resistance. Fully consistently used every swing of the pendulum to move propulsion, both the horizontal and the inclined surface of the low resistance movement. From this propulsion 1, 2 and 3, 4 is increased and the speed and tractive effort, and energy consumption is reduced.

Moving the execution of the hinge on the pendulum, linked through a connecting rod with a crank mechanism, allows a wide range to adjust the speed and traction propulsion in the process of its movement. The scope of such propulsion relative to the propulsion of this class extends, for example, used the and marshy, arable areas, construction of roads for ground leveling. In agriculture when plowing fields and planting crops. In trains at the initial moment of motion and so on.

SUBSTANCE: method for controlling machine for tilling land involves movement and contact of actuating elements of the machine with the soil. The actuating elements are moved a step forward and then stopped. Support keeps the actuating elements from recoiling when other actuating elements and the machine are moved and these movements are repeated for the required number of times and without increasing number of actuating elements and passage on the ground. The load of the wheels of the machine is adaptively reduced without their skidding. When tilling the soil, resistance of the moving actuating element to recoiling is increased or by supports, so that the propulsive force coincides with the required value, or by self rotation of the moving actuating element, turning it into a support-anchor. The actuating elements are moved along the machine to increase speed with little grabbing across - for increasing the width of grabbing, or combining them, thereby increasing the grabbing width. By shifting supports or restrictors, the stepping motion of the actuating elements is reversed. The stepping actuating elements are moved in succession or together depending on the working conditions. When there is differential drive of the actuating elements, the stepping sequence and the speed of motion is determined by the resistance of the actuating elements. Low resistance actuating elements are put in front of elements with high resistance and maintain the working order or protection when obstacles are encountered. The machine for tilling land has a mechanism for movement and lifting actuating elements. The machine also has detachable stepping actuating elements for tilling the land, supports and drives for longitudinal movement, as well as supports and drives for transverse movement of actuating elements. The drive for actuating elements has an oscillation source which is in form of one ball and socket joint or off-axis roller. The machine also has guide actuating elements. Detachable moving actuating elements are in form of a plough, ripper, paring plough, cultivator, bulldozer, grader, grubber, brush breaker, or some other actuating element with supports for generating propulsion force. The detachable actuating elements are mounted on sections of the step pathway. Actuating elements are installed with provision for rotation for adjusting the row spacing.
