Description

The invention relates to wheeled vehicles and is intended to increase their cross-country ability.

Known wheeled vehicle containing a frame, pneumatic wheels, drive, hydraulic or pneumatic system, a remote power cylinder and a power take-off shaft (PTO). [12]

The well-known wheeled vehicle does not have enough high passability in difficult road conditions.

The objective of the invention is to increase the patency of wheeled vehicles.

The problem is solved due to the fact that a wheeled machine containing a frame, pneumatic wheels, a drive, a hydraulic or pneumatic system, an external power cylinder and a PTO, according to the invention, the wheeled machine is equipped with a pendulum vibrator of directional action, mounted on an articulated axis to the frame of the wheeled machine, a pendulum vibrator connected to the PTO, the ends of the power cylinder are pivotally connected to a pendulum directional vibrator and a frame.

Figure 1 shows a wheeled machine with a pendulum vibrator directional configured for forward movement; figure 2 wheeled machine with a pendulum vibrator directional configured for backward movement.

The wheeled machine contains a frame 1 with pneumatic wheels 2, a drive 3, a pneumatic or hydraulic system 4 and an external power cylinder 5. In addition, it contains a pendulum vibrator of directional action 6 located in the front of the wheeled machine and fixed to the frame 1 on the hinge axis 7. Connection PTO 8 and drive 3 is carried out by cardan transmission 9. The ends of the power cylinder 5 are pivotally connected to the pendulum vibrator 6 and frame 1.

Wheel machine operates as follows.

When moving a wheeled vehicle in difficult road conditions (dirt, snow), when the adhesion of the wheels to the soil is not enough, the tractor driver, using the control valve, controlling the power cylinder, sets the pendulum vibrator 6 to the required angle to the horizon, depending on the movement of the wheeled vehicle. Then it includes the PTO 8. The rotation from the PTO through the cardan drive 9 and the drive 3 is transmitted to the pendulum vibrator of directional action 6. During operation of the pendulum vibrator of directional action, a resultant centrifugal force is created. If you transfer the point of application of the resultant force to the center of the hinge axis 3 of the pendulum vibrator 6 to the frame 2 and decompose this force into horizontal and vertical components, then the magnitude of the horizontal force will depend on the operation of the pendulum vibrator of the directed action and its angle of inclination to the horizontal. When the horizontal force exceeds the resistance force of the wheeled vehicle, it will begin to move (forward or backward).
