Detailed description of the invention
For above-mentioned feature and advantage of the present invention can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
As shown in Figure 1 and 2, the variable suspension of a kind of electromagnetic type, comprise the sleeve 4 be fixed on axletree 1 and the cylindrical bar 5 be fixed on vehicle frame 6, the spring 7 of support frame 6 is connected with between described axletree 1 and vehicle frame 6, described cylindrical bar 5 lower end to extend in sleeve 4 and the two bearing fit, the first iron-core coil circuit cylindrical bar 5 being attracted or upwards repels is provided with downwards in described sleeve 4, first iron core 2 lower end of described first iron-core coil circuit is fixed on axletree 1, first iron core 2 upper end of described first iron-core coil circuit is relative with cylindrical bar 5 lower end, described sleeve 4 upper end inwall is provided with the spacing electromagnetic valve 3 for pinning cylindrical bar 5.
In the present embodiment, induction coil one end ground connection of described first iron-core coil circuit, the induction coil other end of described first iron-core coil circuit connects high input voltage joint Vi, and described high input voltage joint Vi is connected with the high-voltage output connector Vo of the second iron-core coil circuit; Described second iron-core coil circuit is similar to ignition coil circuit, to export high pressure.
In the present embodiment, described second iron-core coil circuit comprises the second iron core 8, primary winding 11 and output primary 12, described output primary 12 and primary winding 11 are respectively with the outside of equidirectional around the second iron core 8, the direction of winding of described primary winding 11 is identical with output primary 12 and around the outside of output primary 12, the cross-sectional area of described output primary 12 is less than primary winding 11, the rate of turn primary winding more than 11 of described output primary 12, the top of described primary winding 11 is in series with relay 9 and ground connection, the terminal tandem of described primary winding 11 has variable rheostat 10 and power supply on vehicle 13, the electric current of described primary winding 11 is controlled by the electronic control unit (ECU) of automobile, the top of described output primary 12 is connected with high-voltage output connector Vo, the end of described output primary 12 is connected to the top of primary winding 11.
In the present embodiment, described electronic control unit receives the signal from automobile sensor, and contrast by carrying out analysis with " sensor states-electric current " relation of inner setting, send corresponding instruction, change variable rheostat 10 resistance of low voltage circuit, the electric current of primary winding 11 is changed, and then the output voltage of output primary 12 is changed, the magnetic field of the first iron core 2 is changed, attractive force or repulsive force are produced to cylindrical bar 5, reach the effect changing bodywork height.
Because the second iron-core coil circuit adopts secondary coil, the induction coil voltage of the first iron-core coil circuit can be made to reach several kilovolts instantaneously, allow the first iron core 2 have enough magnetic force, action is carried out to cylindrical bar 5.Because voltage general on car is 24V, therefore one-level coil by the change of electric current in circuit, cannot produce enough magnetic force.And in the circuit of low supply voltage, adopting secondary coil, its momentary voltage can reach several kilovolts, can provide required electromagnetic force.
In the present embodiment, described sensor comprises vehicle body sensor, automobile longitudinal acceleration sensor, vehicle lateral acceleration sensor and crank-position sensor.By the collection of these sensor signals, the change of automobile road conditions can be reacted to electronic control unit quickly and accurately, after the signal that electronic control unit can gather each sensor is analyzed, to actuating unit instruction, change the resistance value of the second iron-core coil circuit low pressure side, to adapt to the requirement to suspension height under each operating mode.
In the present embodiment, when electronic control unit do not send instruction change electric current in the second iron-core coil circuit time, described spacing electromagnetic valve 3 automatic spring, pins cylindrical bar 5, and cylindrical bar 5 ceaselessly can not be slided up and down because not constraint.Described cylindrical bar 5 sidewall is provided with the chute matched with the actuating unit of spacing electromagnetic valve 3, so that slide up and down in sleeve 4.Because cylindrical bar 5 is connected with vehicle body (i.e. vehicle frame 6), therefore vehicle body can move along with the motion of cylindrical bar 5, changes bodywork height in time, to adapt to the ground Clearance requirement of different operating mode.When electromagnetic force and spring 7 are in balance, described spacing electromagnetic valve 3 auto lock, can not make cylindrical bar 5 follow road conditions to slide up and down.
As shown in Figure 1 and 2, the control method of the variable suspension of a kind of electromagnetic type, adopt the variable suspension of electromagnetic type as above, when the high pressure of the induction coil input change of the first iron-core coil circuit, described first iron core 2 produces corresponding magnetic field, to produce downward attractive force or repulsive force upwards to the cylindrical bar 5 be fixed on vehicle frame 6, and then the height of adjustment vehicle frame 6.
In vehicle traveling process, according to the state gathering each sensor, ECU, by analyzing, to the corresponding instruction of controller, changes variable rheostat 10 resistance in circuit, thus electric current is changed.When electric current occurs to become large, the magnetic force of the first iron core 2 is increased, just the cylindrical bar 5 that can slide up and down is adsorbed, make it move downward, when magnetic force cannot overcome when cylindrical bar 5 moves downward, spacing electromagnetic valve 3 auto lock, thus vehicle body is reduced.When electric current diminishes, the magnetic force of the first iron core 2 is reduced, at this time spacing electromagnetic valve 3 one signals can be given simultaneously, it is allowed first to separate with the draw-in groove in cylindrical bar 5, make cylindrical bar 5 upward sliding, when magnetic force is just equal with the elastic force of spring 7, spacing electromagnetic valve 3 automatic spring, block cylindrical bar 5, thus vehicle body is raised.
The present invention does not limit to above-mentioned preferred forms, and anyone can draw the variable suspension of other various forms of electromagnetic types and control method thereof under enlightenment of the present invention.All equalizations done according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
