Description
Technical field：
The present invention relates to a kind of vehicle front independent steering system based on linear electric motors, the independent steering for automobile.
Background technology：
Although what traditional steering (mechanical, hydraulic booster or electric boosting steering system) had developed mutually treats as
It is ripe, and Hyundai Motor is widely used in, but with automobile, the continuous progress of electronic technology and significantly improving for people's living standard,
Conventional steering system can not meet requirement of the people to high-performance steering to a certain extent.Turn compared to traditional
To system, independent steering system can not only overcome problem present in conventional steering system, and can improve the manipulation of automobile
Stability.What the A of patent CN 102874304 were proposed carries out independent steering with electric rotating machine, but because its electric rotating machine is vertical
It is straight to place, above bodywork height is added, driver's seat is influenceed；And its steering motor is exposed outside vehicle body, so as to give
Vehicle body design brings very big difficulty, largely influences car conour attractive in appearance.Due to steering mechanism and the direct phase of electric rotating machine
Even, so noise can be produced when electric rotating machine is responded.
In order to overcome above mentioned problem, and the reliability of independent steering system work is improved, the present inventor is to independent steering
Mechanism, which has been done, further to be researched and analysed, and has invented a kind of vehicle front independent steering system based on linear electric motors.Wherein use
Linear electric motors, be one kind by the way that closed magnetic field is expanded into open magnetic field, electric energy is converted into linear motion
Mechanical energy, without the transmission device of any intermediate conversion mechanism, can be regarded as an electric rotating machine edge from structure
Radially split, and formed by the expansion of the circumference of motor is in line.Wherein stator is equivalent to the primary of linear electric motors, rotor phase
When in the secondary of linear electric motors, after primary is passed through electric current, travelling-magnetic-field is produced in the air gap between primary and secondary, in traveling wave
Magnetic field in the presence of secondary permanent magnet with producing driving force, so as to realize the linear motion of moving component.
The content of the invention：
It is an object of the invention to develop a kind of vehicle front independent steering system based on linear electric motors, before automobile
The independent steering of wheel.To achieve these goals, the present invention is realized by following technical scheme：
A kind of vehicle front independent steering system based on linear electric motors, it is characterised in that including linear electric motors, electric rotating
Machine, bindiny mechanism, transmission mechanism；Wherein, linear electric motors provide power for system；Bindiny mechanism is included with female cylindricality
Branch sleeve and left and right two connectors；Transmission mechanism includes rod head, knuckle arm；Electric rotating machine control left side is connected
Part rotates to an angle, and the neck on left and right connector, latch is mutually closed, and then front-wheel independent steering can be become integral
Formula is turned to.
The near front wheel and off-front wheel described in technical scheme is each to that should have a linear electric motors, and two linear electric motors phases
It is mutually independent, directly drive respective wheel steering motion.The two ends of straight-line electric arbor are tapped with one section of screw thread, wherein one end and cylindricality
Branch sleeve is connected, and the other end is connected with connector.Rod head one end is also tapped, by with female post
Shape branch sleeve is coaxially connected with rod head by motor shaft.Wherein, outside with female cylindricality branch sleeve centre position
Surface mills out two planes, rotates the cylindricality branch sleeve by spanner, thus it is possible to vary the steering locking angle of both sides wheel.Turn to
Joint arm with rod head by being connected, the divertical motion that the transform linear motion of linear electric motors is wheel.
In front-wheel independent steering system described in technical scheme, left side connector one end carries neck, and the other end is carried
Internal thread hole, centre position processes a circle gear teeth, for being meshed with electric rotating machine shaft end gear.Wherein carry internal thread hole
End is connected with the shaft end of left motor by screw thread.Equally, right side connector one end carries latch, and the other end carries internal thread
Hole.Wherein it is connected with internal thread nose end with the shaft end of right motor by screw thread.When a linear electric motors occur in system
Failure and when can not work, adjusting the axial location of another straight-line electric arbor makes neck and the right side connection of left side connector
The latch position of part is aligned, and is controlled left side connector to rotate to an angle by electric rotating machine, is made the card on left and right connector
Groove, latch are mutually closed, and then front-wheel independent steering can be become Integral steering, improve system reliability.
Driving system of linear motor described in technical scheme is eliminated due to the biography that the mechanical mechanisms such as rack-and-pinion are produced
Dynamic gap and error, are reduced because of the tracking error that transmission system hysteresis band comes.Feedback control is detected by linear position, can be big
The big steering precision for improving steering.Because linear electric motors have the high-speed response characteristic of " Zero-drive Chain ", make its acceleration and deceleration
Journey is greatly shortened.Moment is reached at a high speed when being started with realizing, energy moment standard is stopped again during high-speed cruising.Higher acceleration can be obtained
Degree is general up to 2~10g (g=9.8m/s2).
Compared with prior art, beneficial effects of the present invention：
1, due to using linear electric motors, feedback control can be detected by linear position, improve and turn to precision.Simultaneously because straight
The response of line motor is rapid, can reduce turnaround time.
2, because linear electric motors speed is fast, acceleration, deceleration process is short, and fast steering can be achieved and returns just, or even in urgent feelings
Emergency turn can also be realized under condition.
3, due to using linear electric motors, divertical motion can be made quiet, noise is low, and efficiency high.
4, pass through the female cylindricality branch sleeve of the band of be rotatably connected straight-line electric arbor and rod head, it is possible to increase two
The angle range of side deflecting roller.
5, simple in construction, amount of parts is few, and arrangement gets up also relatively easy, and original design need not be carried out big
Variation.
6, when motor breaks down and is stopped, front-wheel independent steering can be become whole by left and right connector
Body formula is turned to, it is ensured that turned under the low speed.Due to adding measures against being out of function, so it is independent to greatly enhance front-wheel
The reliability of steering.
