Axle, variable-length lever, steering wheel tooth bar, pinion frame, gear ring, sun gear, planetary gear, control cable, motor, mistake
Wheel；The sun gear is connected with steering wheel, and the pinion frame is connected with wheel, and the gear ring includes internal gear and external tooth
Wheel, the planetary gear are provided with two；The sun gear and steering wheel tooth bar be intermeshed, and sun gear rotarily drives direction
Disk tooth bar transverse shifting, the variable-length lever is telescopic rod, and its one end is articulated with steering wheel tooth bar, the other end and control
System switch connection, is provided with groove in the variable-length lever, and slidably rotating shaft only can be slided up and down in the groove, the control
On controlling switch tooth bar, the third wheel is intermeshed system switch respectively with the external gear and controlling switch tooth bar of gear ring,
Control signal is sent to motor by controlling cable by controlling switch, and motor is intermeshed with the external gear of gear ring, planetary gear
It is intermeshed with the internal gear and sun gear of gear ring respectively, the two ends of the gear rack are hingedly connected to planetary turn
On axle.
Further, the gearratio of steering mechanism when low vehicle speeds, by slidably rotating shaft moving down, is reduced, is increased
Plus turn round sensitivity.
Further, when the vehicle runs at a high speed, by slidably moving in rotating shaft, the gearratio of steering mechanism, drop are increased
It is low to turn round sensitivity.
Beneficial effects of the present invention are as follows：
The present invention can realize that mechanism's variable gear ratio of turning round of automobile is driven, and the transmission of steering mechanism is reduced in low speed
Than increasing the sensitivity for turning to, increasing the gearratio of steering mechanism during high speed, reduce sensitivity, increase stability during traveling；
Simultaneously, it is not necessary to angular transducer, there is low cost.

Specific embodiment
Below in conjunction with the accompanying drawings the present invention is done and is further explained.
The structure of the controlling organization of the variable ratio steering system of the present invention is as shown in figure 1, including controlling switch 1, control
System switch tooth bar 2, slidably rotating shaft 3, variable-length lever 4, steering wheel tooth bar 5, pinion frame 6, gear ring 7, sun gear 8,
Planetary gear 9, control cable 10, motor 11, third wheel 12.
Sun gear 8 is connected with steering wheel, and pinion frame 6 is connected with wheel, and gear ring 7 includes internal gear and external gear, OK
Star gear 9 is provided with two.
Sun gear 8 is intermeshed with steering wheel tooth bar 5, and sun gear 8 rotarily drives 5 transverse shifting of steering wheel tooth bar.Can
It is telescopic rod to become length lever 4, and its one end is articulated with steering wheel tooth bar 5, and the other end is connected with controlling switch 1.Variable length
Groove is provided with degree lever 4, slidably rotating shaft 3 only can be slided up and down in the groove.Controlling switch 1 is arranged on controlling switch tooth
On bar 2.Third wheel 12 is intermeshed with the external gear and controlling switch tooth bar 2 of gear ring 7 respectively, and controlling switch 1 is by controlling cable
Control signal is sent to motor 11 by 10, and motor 11 is intermeshed with the external gear of gear ring 7.Planetary gear 9 respectively with gear ring 7
Internal gear and sun gear 8 are intermeshed.The two ends of pinion frame 6 are hingedly connected in the rotating shaft of planetary gear 9.
Steering wheel tooth bar 5 is driven by the gear being mounted on steering wheel shaft.Controlling switch 1 is arranged on controlling switch tooth bar 2.
Controlling switch tooth bar 2 is driven by the gear ring 7 of planetary gears.Variable-length lever 4 is made up of two bars, wherein one is inserted in
In another, two bars relative can slide, so as to change the overall length of bar.There is groove in variable-length lever 4, slidably rotating shaft 3
Can slide in groove.Variable-length lever one end is connected with steering wheel tooth bar 5, and the other end is connected with controlling switch 1.Sun gear 8
It is connected with steering wheel, pinion frame 6 is connected with wheel, slidably rotating shaft 3 can only be moved up and down.
The course of work of the controlling organization of the variable ratio steering system of the present invention is as follows：
When driver rotates clockwise steering wheel, as shown in figure 1, steering wheel tooth bar moves right, variable-length thick stick is driven
Bar is moved to right.Because the slidably stop of rotating shaft, the other end of variable-length lever promote controlling switch to the left.Controlling switch
Producing control signal makes motor rotate counterclockwise, so as to drive gear ring to turn clockwise.At this moment sun gear is driven together with gear ring
Pinion frame turns clockwise.Gear ring drives controlling switch tooth bar to move to left by third wheel simultaneously.If now driver stops turning
Dynamic steering wheel, then variable-length lever no longer will push away controlling switch to the left, control signal disappears, motor stalling.
Work as low vehicle speeds, need to reduce the gearratio of steering mechanism, increase is when turning round sensitivity, slidably rotating shaft to
Lower movement, as shown in Figure 2.At this moment steering wheel tooth bar is only needed to move on a small quantity and can just drive controlling switch tooth bar to move on a large scale,
So that Motor drive gear ring is significantly rotated, so as to increase the corner of pinion frame, reduce the gearratio of steering mechanism, increase
Plus sensitivity.
Work as high vehicle speeds, need to increase the gearratio of steering mechanism, when reducing sensitivity, slidably rotating shaft is moved upwards
It is dynamic, as shown in Figure 3.At this moment steering wheel tooth bar movement on a large scale can only drive controlling switch tooth bar to move on a small quantity, so that motor
Driven gear ring is rotated by a small margin, the gearratio of Jian great steering mechanism, reduces sensitivity.
In sum, the controlling organization of variable ratio steering system of the invention can realize that the mechanism that turns round of automobile can
Variable ratio is driven, and the gearratio of steering mechanism is reduced in low speed, increases the sensitivity for turning to, increases steering mechanism during high speed
Gearratio, reduce sensitivity, increase traveling when stability.Angular transducer is not necessary to simultaneously, with the excellent of low cost
Point.
Presently preferred embodiments of the present invention is the foregoing is only, not to limit the present invention.All essences in the present invention
Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
