The present invention tilts the car body inward to prevent the centrifugal force generated when the car is driving on a curve road, and the inclination of the car body to prevent the object or occupant in the car from being moved to the outside (the direction in which the centrifugal force acts). It is about.

Conventional cars have no countermeasures against centrifugal forces, so when turning with a sharp curve, the speed must be sharply lowered to some extent to avoid the outward movement. Since the occupant is forced outward by the centrifugal force, there are various problems, such as falling down if the handle is not caught or falling on the shelf, resulting in injury.

The present invention is to rectify the above-mentioned shortcomings, the automobile is traveling at a high speed on a straight road, but stepped by the brake to rotate on the curve road, the oil is compressed in the hydraulic tank by using the energy consumed at this time ( When brake is normally applied, the same function is applied to the front and rear of the vehicle, and the hydraulic cylinders installed on the undercarriage (spreading base plate) and the wheel axle are operated by compressed oil, respectively. A pair of relays and solenoids are operated by horizontal contact with ground level sensor, and one of the relays and solenoids receiving the electrical signal opens the hydraulic open / close valve, and the oil compressed in the hydraulic tank Is delivered to the hydraulic cylinders and installed on the front and rear wheels, respectively. Shrink or stretch the hydraulic cylinder to raise the body to the inverse of the horizontal or inclination. When the body is raised as much as desired in the horizontal or reverse direction, the electrical contact of the horizontal sensor is automatically cut off and the electrical is transmitted to the relay and the solenoid. The signal is cut off to maintain the stable state of the vehicle body. The degree of inclination of the vehicle body depends on the driving speed and the radius of the curve and is automatically adjusted. When driving in a straight line after the end of rotation operation, the opposite relay, solenoid and hydraulic opening / closing valve are operated by the horizontal sensor immediately, and the vehicle body is automatically leveled again, even when the road surface is tilted left and right. The body is always leveled by the operation of.

Hereinafter, the contents will be described in detail with reference to the accompanying drawings.

The oil in the oil storage chamber 1 is the solenoid S ₁ receiving the electrical signal from the relay L ₁ closes the on-off valve 3 of the bypass pipe 2 so that the compressor 4 causes the hydraulic tank ( 5) The oil is compressed by the oil, and the compressed oil transmits the hydraulic signal of the horizontal sensor (6) to the relay (L ₂ ) (L ₃ ) and the hydraulic open / close valve (7) (7 ') (8) (8'). The solenoid (S ₂ ) (S ₃ ) operating the expansion chamber (10) of the hydraulic cylinder (9) (9 ') from the hydraulic tank (5) through the hydraulic opening and closing valve (7) (8) 10 ') or oil pressure is delivered to the shrinkage chambers 11 and 11', the oil of the shrinkage chambers 11 and 11 'or the expansion chamber 10' is passed through the hydraulic opening and closing valves 7 'and 8'. The oil flows into the storage chamber 1 and is reduced. At this time, when the hydraulic cylinders 9 and 9 ', which are expanded or contracted by the introduced hydraulic pressure, are operated at an appropriate amount, the electrical contact portions 22 and 22' of the horizontal sensor 6 are operated. ) Is cut off, or the vehicle is tilted when excessive operation is required Is by the device 12 relays (L ₂₎ (L ₃₎ and Soleil Lloyd (S ₂₎ since (S ₃₎ electrical signal is blocked, the oil pressure switching valve 7 (7 ') (8) (8') Closed to shut off the hydraulic flow, and also upsore, which is improved solenoid (S ₄ ) (S ₄ ') by the relay (L ₂ ) (L ₃ ) at the same time the operation of the hydraulic cylinder (9) (9'). The shock absorbing action is interrupted through the breaker 14 of the bar 13 to quickly transmit or contract the expansion or contraction action of the hydraulic cylinders 9 and 9 '.

Reference numeral 15 is the main switch, 16 is the switch, 17 is the brake micro switch, 18 is the accelerator pedal micro switch, 19 is the handle micro switch, 20 is the pressure sensing switch (for high pressure cutoff), 21 is the pressure sensing switch (low pressure contact). 22, 22 'are horizontal sensor contacts, 23, 23', 24, 24 'are pipes, 25, 25' are limit switch, 26, 26 ', 27, 27' are spring, 28, 28 'are cylindrical Oil canister, 29 is communicating tube, 30, 30 'bellows, 31, 31' crimp, 32, 32 'top, 33 axle, 34 connecting rod, 40, 40' chassis, 41, 41 'wheel , 42 and 42 'center axis, 43 and 43' bodywork, 50 horizontal sensor, 51 oil sump, 52 diaphragm, 53 and 53 'horizontal sensing weight, 54 and 54' connecting rod, 55 and 55 ' Is the horizontal sensing contact, 56, 56 'is the support shaft, A is the safety valve B is the oil pipe to reduce the oil by the action of the safety valve.

According to the present invention, if the switch 16 is turned on in the state where the main switch 15 of the vehicle is turned on, and the brake is pressed even slightly (shallowly), the microswitch 17 attached thereto is turned on and the relay (L _1). ), And the micro switch 19 installed here is turned ON even when the steering wheel is rotated in either direction while the accelerator pedal is pressed (the accelerator pedal micro switch is ON). Since the microswitches 19 and 18 are energized in series, an electrical signal is also transmitted to the relay L ₁ so that the solenoid S ₁ opens and closes the valve 3 of the open bypass pipe 2. Oil is introduced into the hydraulic tank (5) by the compressor (4), which is closed. To make it work It is very effective, and it is possible to greatly reduce the wear of the brake lining by utilizing the energy that is consumed when the brake is applied, rather than directly compressing the oil to the hydraulic tank 5 by the power of the engine, or to reduce the curve length. When trying to run at high speed is a compression operation made to compress the hydraulic tank (5) is to naturally decelerate to prevent the accident before.

The pressure sensing switch 20 installed in order to detect the pressure state of the hydraulic tank 5 has a sufficient pressure state in the hydraulic tank 5, and the contact is cut off, and the electrical signal transmitted to the relay L ₁ is blocked. At this time, the solenoid S ₁ opens the shut-off valve 3 to idle the compression pump of the compressor 4 so that no more pressure is required in the hydraulic tank 5 so that the overpressure of the hydraulic tank 5 or the compressor 4 ) To prevent an overload from occurring, and in another way (not shown) to remove the open / close valve (3) and to receive an electrical signal while the compressor (4) is stopped rotating. The solenoid S ₁ is a device that rotates the compressor 4 only during energization.

On the contrary, when the pressure of the hydraulic tank 5 is very weak, the pressure sensing switch 21 is turned on so that an electrical signal is transmitted directly from the switch 16 to the relay L ₁ so that the solenoid S ₂ is discharged. By the operation, when the oil pressure (approximately 1/2 to 2/3 of the operation of the pressure sensing switch 20) is appropriate to the hydraulic tank 5, the pressure sensing switch 21 (for contacting) is turned OFF.

When the contacts 22 and 22 'of the horizontal sensor 6 form the contacts 22 and 22' due to the action of the centrifugal force of the vehicle body or the degree of inclination of the road surface, the electrical signals are relays L ₂ and L ₃ . Is transmitted to the solenoid (S ₂ ) (S ₃ ) by the relay (L ₂ ) (L ₃ ), the solenoid (S ₂ ) (S ₃ ) is a hydraulic opening and closing valve (7) (7 ') ( 8) Opens the 8 ', so the hydraulic pressure of the hydraulic tank 5 passes through the pipes 23, 23' of the expansion chambers 10, 10 'or contraction chambers of the hydraulic cylinders 9, 9'. 11) When the hydraulic cylinder (9) (9 ') is introduced into the contraction or expansion, one side of the vehicle body is raised, when the hydraulic cylinder (9) (9') is expanded or contracted when the hydraulic cylinder The oil flowing into the (9) and (9 ') is reduced to the oil storage chamber (1) through the valves (24', 24 ') and the valves (7', 8 ') opened.

When the body rises or falls above the threshold, the contacts of the limit switches 25 and 25 'are blocked, so that the relays L ₂ and L ₃ and S ₂ S ₃ deliver electrical signals. As the operation is stopped, the hydraulic open / close valves 7, 7 ', 8, and 8' are closed by springs 26, 26 ', 27 and 27' and the hydraulic transmission is interrupted. 9) The operation of (9 ') is stopped to prevent the inclination of the vehicle body to rise or fall above the threshold.

In order to quickly transfer the action of the hydraulic cylinders (9) and (9 ') to the vehicle body, the electrical signals are transmitted to the solenoid (S ₂ ) and the solenoid (S ₃ ) by the relays (L ₂ ) and (L ₃ ). (S ₄ ) It is also transmitted to (S ₄ ′) to block the breaker 14 of the improved upshor bar 13 to block the movement of oil in the upshor bar 13, thereby improving the shock absorber ( 13) the solenoid (S ₄ ) (S ₄ ') to instruct the operation of the breaker (14) of the up-show bar (13) of the relay (L ₂ ) or relay (L ₃ ) Either way, if only one side of the contact is made as described above, the functional stop action of the improvement upshoe bar 13 is made together, which is installed auxiliary, the hydraulic cylinder (9) by the rapid action of the horizontal sensor (50) (9 ') is activated.

In the present invention, the energy (oil extruding force) required for operating the hydraulic cylinders 9, 9 'is compressed by the oil in the hydraulic tank 5 during normal driving, and then opened and closed valves 7, 7' by electrical contacts. (8) (8 ') is open and operated. This means that the body 43 (engines, occupants and facilities, etc.) is excluded except for the wheel system 41 and the shaft system to which the wheels are attached, as shown in FIG. The weight ratio of the upper and lower portions is formed so that the lower portion is slightly heavier (the weight ratio changes somewhat due to the weight of the occupant). When the vehicle is inclined to the outside by the road surface or centrifugal force tilted left and right, the vehicle body 43 placed on the buffer coil springs provided on both ends of the curved chassis 40 coupled to the central axis 42 As the lower part is pushed outwards, the upper part Since the cylinder 42 is pushed inward from the starting point, the hydraulic cylinder 9, 9 'is operated even without the hydraulic cylinder 9, 9'. Therefore, the hydraulic cylinder 9, 9 'can be operated with a small force. It can be miniaturized, and also prevents rocking of the vehicle body 43 (shake to the left and right) to ensure safe and quick operation.

This action works faster as the position of the central axis 42 is increased to increase the weight ratio of the upper and lower parts, but this causes various difficulties in manufacturing (the prevention of shaking to the left and right is solved by constructing the upshow bar). In order to increase the weight ratio of the upper and lower bodies 43, the present invention selects the position of the central shaft 42 as low as possible and installs the engine, the auxiliary parts, and the seat of the occupant low.
