The structure that the interior fork-shaped rotor of the error correction brake system core component of the utility model is the fixedly electromagnetic valve 14 of corner is explained as follows:
The opposite face meaning that the opposite face of overcoat fixed body 2 arc inner walls is provided with a pair of permanent magnetic iron block 4 is: the opposite face of a certain diameter of these a pair of permanent magnetic iron block 4 its external sleeve fixed bodies 2.
When all coil 6 is all non-conductive, always there are the two ends of a straight shape iron core 7 to be attracted in " ten " font iron core 5 by two block permanent magnet pieces 4 of opposite face in the overcoat fixed body 2, make the two ends of this straight shape iron core 7 very near from two block permanent magnet pieces 4.And the two ends, two ends of another straight shape iron core 7 are far away from two block permanent magnet pieces 4 in " ten " font iron core 5.
The principle that interior fork-shaped rotor 1 corner is a fixed value is: because in " ten " font iron core 5, become coil 6 on two straight shape iron cores 7 that " ten " word intersects after conduction, make the two poles of the earth of two straight shape iron cores 7 all become the magnetic pole of electromagnet.If after first coil 6 conductions above straight shape iron core 7 that quiescence is attracted by two block permanent magnet pieces 4; Make two electromagnetism magnetic poles of this straight shape iron core 7 become the arctic to the South Pole with the magnetic pole of two block permanent magnet pieces 4; Because opposite pole attracts mutually; Then interior fork-shaped rotor 1 just can not relatively rotate with overcoat fixed body 2, and promptly interior fork-shaped rotor 1 can not rotate.But after first coil 6 conductions above straight shape iron core 7 that quiescence is attracted by two block permanent magnet pieces 4; Making two electromagnetism magnetic poles of this straight shape iron core 7 become an end with the magnetic pole of two block permanent magnet pieces 4 is that the arctic is to the arctic; The other end is that the South Pole is to the South Pole; Because like pole repels mutually, the relative permanent magnetic iron block 4 of two south poles that is fixed on overcoat fixed body 2 inner faces then can repel first straight shape iron core 7, and attracts second straight shape iron core 7; Make the magnetic pole South Pole of second straight shape iron core 7 and permanent magnetic iron block 4 that magnetic pole is the arctic approaching, make the magnetic pole arctic of second straight shape iron core 7 and permanent magnetic iron block 4 that magnetic pole is the South Pole approaching simultaneously.Like this; The relative permanent magnetic iron block 4 of two south poles in the overcoat fixed body 2 pushes away first straight shape iron core 7 repulsions far away; Second the straight shape iron core 7 that attracts magnetic pole to inhale mutually again simultaneously; Thereby " ten " font iron core 5 of fork-shaped rotor 1 produces relative rotation the purpose that fork-shaped rotor 1 is rotated in reaching with overcoat fixed body 2 two interior block permanent magnet pieces 4 in making.Because overcoat fixed body 2 is fixed on other motionless object, then interior fork-shaped rotor 1 can be used as propulsion source and drives other movable object, as can be used as the propulsion source of pulling braking automobile pedal.
When all coil 6 was all non-conductive, the angle between the straight shape iron core 7 at the opposite magnetic pole end place of first straight shape iron core 7 and second straight shape iron core 7 was exactly the constant rotation angle of interior fork-shaped rotor 1.Because two straight shape iron core 7 angles in " ten " font iron core 5 are constant, then in the pivot angle of fork-shaped rotor 1 be exactly the numerical value of this angle, can not change.The pivot angle of fork-shaped rotor 1 was a definite value in " ten " font iron core 5 made, and the pivot angle of fork-shaped rotor 1 was different in different angles " ten " font iron core 5 made.If change the output pivot angle of interior fork-shaped rotor 1, then must to change the angle of " ten " font iron core 5 interior two straight shape iron cores 7.

Straight shape iron core 7 is " worker " font.Make the two ends of straight shape iron core 7 more roomy, prevent that coil 6 from skidding off from the termination of straight shape iron core 7.
On the same straight shape iron core 7 two or more coils 6 are arranged, these two or more coils 6 around to identical.Coil 6 on the straight shape iron core 7 is the effects that make straight shape iron core 7 produce electromagnet, in order to make the condition of the whole coils 6 on the straight shape iron core 7 in the identical conduction amount, lets this straight shape iron core 7 produce maximum magnetic flow, then all coils 6 around to just should be identical.
Interior fork-shaped rotor is that central rotating shaft 3 outside faces of the electromagnetic valve 14 interior fork-shaped rotors 1 of fixedly corner are connected with an end of stay cord 8.Stay cord 8 is interior fork-shaped rotor 1 output rotation displacements and the device that rotates strength.
" fixing " two word implications of overcoat fixed body 2 are in working order; Overcoat fixed body 2 is to captive joint with other the fixed object beyond the utility model; Make the overcoat fixed body 2 can be because of to the utility model power supply and move other fixed object such as car crust, geodetic ground etc.
The interior fork-shaped rotor of the utility model is that electromagnetic valve 14 preferred structures of fixedly corner are following:
Interior fork-shaped rotor is 7 one-tenth 1 ~ 179 degree of two the straight shape iron cores angle of fixedly " ten " font iron core 5 of the electromagnetic valve 14 of corner.
Be the fixing electromagnetic valve 14 of corner for different interior fork-shaped rotors; 7 one-tenth 1 ~ 179 of two straight shape iron cores of " ten " font iron core 5 degree angle all can, then different interior fork-shaped rotors is 1 ~ 179 to spend and all can for fork-shaped rotors 1 rotatable angle in the electromagnetic valve 14 of fixing corner.Just different interior fork-shaped rotors for the some values in 7 one-tenths 1 ~ 179 degree of 14, two straight shape iron cores of the electromagnetic valve angular range of fixing corner all can, it is that the interior some values of 1 ~ 179 degree scope all can that interior fork-shaped rotor 1 turns the angle.
Interior fork-shaped rotor is that fixedly the straight shape iron core 7 of the electromagnetic valve 14 of corner is " worker " font; On the same straight shape iron core 7 of interior fork-shaped rotor for the fixing electromagnetic valve 14 of corner two or more coils 6 are arranged, these two or more coils 6 around to identical.
Make the two ends of straight shape iron core 7 more roomy, prevent that coil 6 from skidding off from the termination of straight shape iron core 7.Coil 6 on the straight shape iron core 7 is the effects that make straight shape iron core 7 produce electromagnet, in order to make the condition of the whole coils 6 on the straight shape iron core 7 in the identical conduction amount, lets this straight shape iron core 7 produce maximum magnetic flow, then all coils 6 around to just should be identical.

The advantage of the utility model: the sensor of the utility model is installed in the position that can obtain automobile accelerator pedal or throttle system action actuating signal; With the interior fork-shaped rotor of the utility model is that fixedly the central rotating shaft of the interior fork-shaped rotor of the electromagnetic valve of corner is connected with braking automobile pedal or brake system with stay cord or alternate manner; This automobile is become can be with the driver when answering emergency brake, and mistake has been stepped on Das Gaspedal and converted the safety automobile that emergency brake is moved to.From finding that step on the gas electromagnetic valve action fast to the speed of response that is corrected as brake, that drive brake by mistake is accurate, do not have the stall problem, can be in braking state for a long time; Can realize that the full automaticity error correction starts brake and hand reset, the time that hand reset makes braking state is restricted not.
The utility model can be automatically convert the mechanical action that pulling drives brake pedal or its mechanism to missing the step on the gas signal, can automatically reset, get ready for use next time, but manual reset again, to guarantee to have the brake time of artificial needs.And error correction brake automatically, with automatically reset and manual reset etc. same system is arranged all.
The utility model with electromagnetic valve as actuating unit; Than with electrical motor as the advantage of actuating unit being: the electromagnetic valve takeoff output curve of the utility model is the back maintenance Cheng Pingwen straight line that jumped 0.01 ~ 0.05 moment in second; The dynamic curve of brake pedal or its mechanism's needs when just in time being fit to emergency brake; Just the working curve of electromagnetic valve is identical with the working curve that brake needs, completion emergency brake action that just can be best.And all be as actuating unit with electrical motor in the error correction brake system technology of existing mistake step on the gas; And the motor power delivery curve needs strength for wanting just can reach emergency brake after the arc rising slowly 1.50 ~ 2.50 seconds; The working curve that the working curve of electrical motor and brake need is inequality; Can not well realize urgent needs, make long, the braking distance prolongation of brake time, thereby possibility of accident occurrence be higher.
In the utility model the fork-shaped rotor for the fixing advantage of the electromagnetic valve of corner be a kind of speed of response fast, can have dynamic and static two kinds of mode of operations, that place restrictions on pivot angle, fixed starting-point and telemechanical track are arranged, do not have the stall problem, power exports the movement in a curve electromagnetic valve that approaches steady state value:
［ 1 ］ speed of response is fast: so starting emergency brake and making brake pedal reach 0.01 ~ 0.05 second only needed time of complete braking state with the automobile of the error correction brake system of the utility model; Its reason is that the central rotating shaft of the interior fork-shaped rotor of electromagnetic valve can directly be connected with brake pedal or brake system with stay cord; And existing various mistake step on the gas error correction brake system all to be turning cylinder with electrical motor pass through mechanicals device such as change-speed box, displacement limiter as the intermediary movements transmission, and consumed the time of protecting expensive startup brake pedal most.The fork-shaped rotor is that fixedly why the interior fork-shaped rotor central rotating shaft of the electromagnetic valve of corner can start brake pedal in 0.01 ~ 0.05 second in the utility model; Be because after the energising; Coil in the electromagnetic valve can produce galvanomagnetic effect in 0.01 second, and the fork-shaped rotor receives magnetic action and rotates in making.
［ 2 ］ dynamic and static two kinds of mode of operations are arranged: when starting building to refer to start emergency brake, drive brake pedal or other braking mechanism thereby power supply rotates the rotor of electromagnetic valve rapidly as state.Quiet mode of operation refers to that solenoid-driven brake pedal or other braking mechanism are after normal danger; Electromagnetic valve can not wanted power supply still can keep the loading mode of operation, remains on braking state when promptly power supply still can not make brake pedal or other braking mechanism infinitely.Because no matter electromagnetic valve behind once electrification, is to keep energising or outage, it is motionless that the rotor of electromagnetic valve keeps, and can make by the driving object and remain on the fixed position forever.If let the electromagnetic valve outage, keep a certain state then not need power consumption for a long time, be a kind of energy-saving machinery design.Existing motor keeps rotating in that "on" position is then essential, if placed restrictions on rotation then produced the stall problem, and not only power consumption, and possibly in seconds generate heat and burn out motor.The electromagnetic valve of the utility model is can also export certain strength without power consumption to keep object to be in a certain location status and not have the stall problem.
［ 3 ］ the takeoff output curve of suitable emergency brake needs: 0.01 ~ 0.05 moment in second that electromagnetic valve is beginning to switch on; Horsepower output can be near the maximum output power value; Output power value between whole motor area approaches steady state value, that is to say steady straight line work of basic one-tenth.And the output power value of existing motor is from the big arc working curve of little change.The mode of these two kinds of horsepower outputs respectively has purposes, and the electromagnetic valve of the utility model is suitable for the problem of emergent driving device class.
［ 4 ］ electricity can be only as the usefulness that changes sense of motion; And be not used in load: on the fork-shaped fixed body around coil in the effect of magnetic force that initial condition produces of conduction; Mainly be to make rotor turn to another dead position from a dead position, promptly coil produces advocates to act on is the sense of motion that changes rotor, and the power that coil produces is not to be mainly used in the driving load; So import the strength that very little energy just can be used permanent magnet, make rotor obtain very big turning effort.Again since this electromagnetic valve can not consume energy by no power keeping stablize the strength output state, so this electromagnetic valve be energy savings, have environment protection significance, quick operated start, fast export high-power, power output steady, rotational angle accurately, export the accurate electromagnetic valve of displacement length.
［ 5 ］ forced stroke is accurate: behind once electrification; The rotor of electromagnetic valve only rotates some angles of 1 ~ 179 degree; Promptly the pivot angle of an electromagnetic valve is a changeless value; And scope is in 1 ~ 179 degree, and this is best propulsion source for the machinery that ask for something limits displacement.Having saved spacing rotating motor places restrictions on the mechanism that electrical motor rotates or makes mechanical drive produce to skid with additional mechanical and place restrictions on the mechanism of rotation.
［ 6 ］ volume is little in light weight: if stroke reaches 6 centimetres, and 50 kilograms of starting loads, then weight needs only 2 kilograms, and volume needs only long 15 centimetres of 10 centimetres of * of diameter, and cost is extremely low, and not power consumption of static load, on automobile, the installation site can be arranged, and is practical.If but general electromagnetic valve stroke reaches 6 centimetres, 50 kilograms of starting loads, then weight is wanted more than 100 kilograms; Volume wants 20 centimetres of * of diameter long more than 30 centimetres, and cost is high, and the static load power consumption; Do not have so big installation site at automobile, can not use as the error correction brake system.

The specific embodiment
Embodiment 1, in the S. A. error correction brake system of rotatable fixedly angle electromagnetic valve
Like Fig. 1,2,3; Comprise the sensor 9---transducing signal analyzer 10---control signal amplifirer 11---power-supply controller of electric 12 that is connected successively in order to transmit electric signal; With in order to change into mechanical energy to electric energy, and use power-supply controller of electric 12 be connected with in the fork-shaped rotor be the fixing direct supply 15 of the electromagnetic valve 14 of corner for the fixing electromagnetic valve 14 of corner is connected the interior fork-shaped rotor of driving with power-supply controller of electric 12.
Be explanation below to each parts:
Sensor 9 is a certain of pressure sensor, speed sensor or acceleration pick-up or its combination; Sensor 9 is transferred to transducing signal analyzer 10 with transducing signal.In other words; Sensor 9 is a certain with in pressure sensor, speed sensor or the acceleration pick-up; Also can be that pressure sensor, speed sensor and acceleration pick-up all use; Even the rang sensor of Slope Transducer and mensuration and encumbrance distance can also be arranged; All be transferred to transducing signal analyzer 10 to the output signal of these different sensor respectively, the signal of 10 pairs of various sensors of transducing signal analyzer is analyzed, and judges whether to belong in the time of should braking and mistake has been stepped on throttle.
