    BACKGROUND OF THE INVENTION
    Nowadays, vehicles and their trailers are equipped with wheels on both sides. Rear view of the vehicle or trailer, with left and right wheels. The wheels may be twin wheels as in trucks or individual wheels as in cars. The vehicle can be a lorry or a forest truck used for transporting or felling, pruning and cutting wood. The trailer can be a truck trailer or a forest trailer.
    Nowadays, vehicle wheels wear so-called road surfaces or other means of transport. wheel grooves. A higher point is left between the wheel tracks, i.e. the road surface does not wear out smoothly, resulting in the wheel grooves being filled or the entire road surface being replaced. Especially in winter, the icy road surface between the wheel tracks is dangerous, especially in overtaking situations. The tracks of the forestry machine make adjacent grooves, the depth of which must not exceed the legal limits. If the depth of the grooves is exceeded, it is necessary to make new tracks or stop driving the forest machine, which will interrupt logging and timber transportation.
    PURPOSE OF THE INVENTION
    The object of the invention is that the tread is worn evenly. It is a further object of the invention that the point between the wheel tracks can also be used to support the vehicle or trailer by means of added pressure equalization wheels, whereby the surface pressure exerted by the vehicle or trailer on the tread is best balanced across the width of the vehicle or trailer.

    The present invention relates to a method for equalizing the pressure exerted on a vehicle and / or trailer traction unit.
    It has now been found that between the right and left wheels Ib of the vehicle and / or trailer 1, there is one or more pressure equalizing wheel / pressure equalizing gear 2 movably mounted up or down on the axle / axle body la and / or between the right and left wheels. The one or more pressure balancer / pressure balancer 2 can be pressed down with the desired force by one or more lifting / lowering members 4, which is a pneumatic or hydraulic cylinder or a pneumatic cylinder or a combination of any of the foregoing. The one or more pressure compensating wheel / pressure compensating gear 2 can be raised or lowered by one or more lifting / lowering members 4, which is a pneumatic pad or a hydraulic cylinder or a pneumatic cylinder or a combination of any of the above. One or more of the differential / differential 2 is located in front of the axle / axle le between the right and left wheels Ib.

One or more of the differential / differential 2 can be depressed down by the desired force by one or more lifting / lowering members 4, and that the downward force of the differential / differential 2 is the pressing force of the wheels Ib against the chassis from which the force is automatically controlled by the downward pressure of the pressure equalizer wheel / pressure equalizer 2 by one or more control / measurement units 5. The control / measurement unit 5 may be a known computer, programmable logic controller or similar known device for other controls, and which can read, for example, one or more measuring elements of the air pressure, or measure the travel distance, e.g., the compression distance of the suspension. The regulating / measuring unit 5 operates via a wireless or wired connection. One or more of the pressure equalizing wheel / pressure equalizing gear 2 is pivotable so that it does not resist the pivoting movement of the vehicle or trailer 1. One or more of the balancer / pressure balancer 2 is best fitted with studs on winter tires, whereby the balancer / balancer 2 effectively prevents skidding and is also an aid in braking. In addition, the pressure equalizing wheel / pressure equalizing gear 2 with studs efficiently consumes the non-worn part 1 Ib between the grooves 11a, whereby the carrier 11 is leveled.
    USE OF THE INVENTION
    The pressure equalizing wheel / pressure equalizing gear 2 can be raised and lowered automatically or mechanically, for use in the desired operating range, controlled by the regulating / measuring unit 5. The PTO / PTO 2 acts by measuring and comparing the movement of the spring (s) of the rightmost (right and left) wheels Ib or the pressure of the PTO / PTO (PTO), surface pressure relative to the carrier 11. On the grooved tread 11a, the pressure on the tread 11 / pressure differential 2 on the tread 11 automatically increases to a predetermined limit, which is controlled and controlled by the adjusting / measuring unit 5. increases, whereby the pressure of the outermost wheels Ib is reduced, whereby the wear of the grooves 11a of the carrier 11 is substantially reduced.
    Pressurizing wheel / pressure wheel 2 printing with pneumatic spring, pneumatic cylinder, hydraulic cylinder with or without battery. Pressure equalization wheel / pressure equalization gear 2 can be tracked for lifting, facilitating turns and avoiding obstacles such as stumps and rocks in forest machinery for use in forest trailers.
    The regulating / measuring unit 5 controls the pressure equalizer wheel / differential pressure regulator 2 via wired or wireless control. The wired control can be done e.g. by a known CAM bus and the wireless control can be done by any known wireless technology e.g. known from mobile phones. The control / measurement unit 5 is best located in the cab 8 of the vehicle 1.13 The control / measurement unit 5 also has monitoring devices for the vehicle driver, which quickly detects, e.g. 2 up to the upper position, wherein the pressure equalizer wheel / pressure equalizer gear 2 does not touch the carrier 11 at all, regardless of the appearance of the carrier 11, e.g., if there is a carrier or rock in the middle of the carrier. The adjusting / measuring unit 5 raises / lowers the pressure compensating wheel / pressure compensating gear 2 upwards, eg at steep turns such as junctions, e.g. when turning from a forest car road to a main road, making turning easier. The adjusting / measuring unit 5 reads the position of the trailer turntable and deduces a sharp turn. The adjusting / measuring unit 5 may also have a built-in compass or may also detect a steep turn, whereby the adjusting / measuring unit 5 will raise / lower the pressure relief wheel / pressure relief gear 2 upwards. The adjusting / measuring unit 5 can, for example, by means of pivot sensors monitor the position of the vehicle's front wheels even from the track rod or other suitable position, as the front wheels turn to a predetermined angle the adjustment / measuring unit 5 raises / relieves the pressure balancer / As mentioned above, the vehicle can also be controlled by the adjusting / metering unit 5 to raise / lower the pressure equalizer wheel / pressure equalizer 2 when driving manually, eg in urban areas with steep intersections and rarely in the streets due to low driving speeds.
    The vehicle driver or the automatic adjustment / measurement unit 5 can raise / lower the pressure equalizer wheel / pressure regulator 2 upwardly even when the vehicle or trailer is heavily tilted due to the transport platform 11, thus preventing the vehicle or trailer 1 from tipping over. The adjusting / measuring unit 5 is equipped with known tilt-sensing equipment (e.g., like ship compasses), when the tilt reaches a predetermined angle, the pressure equalizing wheel / pressure equalizing gear 2 is raised while simultaneously increasing the pressure of the the pressure Id of the suspension Id so that the vehicle or trailer 1 turns to a more straight or straight position.
    Unlike the figures, the pressure equalizer wheel / pressure equalizer 2 can be mounted to the body 1a without suspension, whereby the lift / lower member 4 raises and lowers the pressure equalizer wheel / pressure equalizer 2 e.g. as shown in FIG. Further, unlike the pictures, there may be only one ring instead of twin wheels, and there may be more than two rings in parallel, e.g. 3-4 in parallel or more.
    It will be apparent to one skilled in the art that the invention is not limited to the above alternatives, but that many modifications are possible within the scope of the inventive concept defined in the appended claims.
