The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, the present invention includes the steering control mechanism that steering shaft 2 and safety coupling 3 are formed by bearing circle 1; By gear, the rack-and-gear steering hardware that tooth bar is formed; One end of two steering track rods 8 links to each other with tooth bar, and the other end of two steering track rods 8 links to each other with the wheel flutter of both sides respectively.The rack-and-gear steering hardware that described tooth bar is formed: comprise turning to dual gear 4 for a short time, turn to dual gear 5 greatly, steering inner articulated shaft 6, be contained in " Γ " type tooth bar 7 in the steering gear housing 9, gear 10, inner gear driving lever 11, driving lever magnetic block 12, driving lever supporting seat 13, electromagnet 14, inner gear 15; Install successively on the steering inner articulated shaft 6 and turn to dual gear 4 for a short time, gear 10 and turn to dual gear 5 greatly, gear 10, for a short time less in turning to less in the dual gear 4 gear and turning to dual gear 5 a greatly gear is all identical, for a short time turn to less in the dual gear 4 gear and turn to the both sides of less in the dual gear 5 gear greatly towards gear 10, for a short time turn to dual gear 4 and turn to dual gear 5 equal skies to be enclosed within on the steering inner articulated shaft 6 greatly, steering inner articulated shaft 6 is connected with safety coupling 3, for a short time turn to bigger in the dual gear 4 gear and the long heel teeth of " Γ " type tooth bar 7 to mesh, turn to the minor face tooth engagement of bigger gear of dual gear 5 and " Γ " type tooth bar 7 greatly, 7 of " Γ " type tooth bars are equipped with inner gear 15, inner gear 15 all can be meshed with three gears of 7 of " Γ " type tooth bars, inner gear is equipped with inner gear driving lever 11 between 15 lower surfaces, inner gear driving lever 11 1 ends are positioned between inner gear 15 lower surfaces, the other end is positioned at 14 of two blocks of electromagnet, the hinged driving lever supporting seat 13 in inner gear driving lever 11 middle parts, " Γ " type tooth bar 7 is connected with two steering track rods 8.
Described gear 10 turns to less in the dual gear 4 gear for a short time and turns to the geometric parameters number average of less in the dual gear 5 gear identical greatly.
Principle of work of the present invention is as follows:
The present invention has changed the situation that traditional deflector has only a transmitting ratio, at the steering inner articulated shaft middle part, gear 10 connects firmly mutually with steering inner articulated shaft, it can only be with steering inner articulated shaft, rotate with unequal angular velocity, and can not relative rotation be arranged with steering inner articulated shaft, in these gear that connects firmly 10 both sides, be equipped with along the axis direction of steering inner articulated shaft and turn to dual gear 4 for a short time and to turn to dual gear 5 greatly, parameters such as the modulus that this two cover turns to the miniature gears in the dual gear and the number of teeth are all identical, and this two cover turns to the modulus of the big gear wheel in the dual gear identical, but the number of teeth is different with reference diameter, these two turn to double sided gear because sky is enclosed within on the steering inner articulated shaft, can sway, and needn't rotate synchronously with steering inner articulated shaft.When automobile on demand, in the time of need turning to traditional lower turning rate, electromagnet on the bearing circle is by attracting the driving lever magnetic block, make driving lever with inner gear gear with turn to dual gear to link for a short time, in this state, because the conjugation of inner gear, for a short time turn to dual gear to be equivalent to connect firmly on steering inner articulated shaft, its rotational angular and angle can only be consistent with the cireular frequency and the angle of steering inner articulated shaft, and the dual gear that turns to greatly of opposite side has been thrown off with inner gear this moment, it rotates the influence that is not subjected to steering inner articulated shaft, can different cireular frequencys be arranged with it, the calibration circle diameter is D on the steering gear in the dual gear if turn to greatly, for a short time turn to that the calibration circle diameter is d on the steering gear in the dual gear, in this case, when bearing circle rotates an angle δ, owing to be equivalent to connect firmly on steering inner articulated shaft, for a short time turn to dual gear also to rotate one and bearing circle angle same δ, so the distance that tooth bar is passed by is δ * d, how many distances because " no matter Γ " type tooth bar is passed by, it is the same all the time with the distance that two gears difference ingear parts are moved, the distance that every bit is passed by on the big gear wheel reference circle is similarly δ * d as can be known, but because the reference diameter of big gear wheel is D, so its angle that turns over only is (δ * d)/D, visible big gear wheel is littler than the angle that miniature gears turned over.In this process, the direction that tooth bar moves is certain, so the rotation direction of the rotation direction of big gear wheel and miniature gears too, just its angle that turns over is less.Another kind of situation, in the time of need turning to higher turning rate, electromagnet is by attracting the driving lever magnetic block, driving lever is engaged inner gear with turning to dual gear greatly, in this state, because the effect of inner gear, turn to dual gear to be equivalent to connect firmly on steering inner articulated shaft greatly, its rotational angular and angle can only be consistent with the cireular frequency and the angle of steering inner articulated shaft, and the dual gear that turns to for a short time of opposite side has been thrown off with inner gear this moment, and it rotates the influence that is not subjected to steering inner articulated shaft, can different cireular frequencys be arranged with it, in like manner, with top data, after bearing circle turned over angle δ, big gear wheel equally also turned over δ, because its reference diameter is D, so the distance that this hour rack is passed by is δ * D, tooth bar drives every bit on the miniature gears reference circle simultaneously and turns over equally apart from δ * D, could satisfy above-mentioned requirements and miniature gears need turn over the angle of δ * D, as seen also big gear wheel is identical for the miniature gears hand of rotation, and the angle that is turned over is bigger than big gear wheel.So just realized that the turning rate of automobile steering device can regulate.
The above-mentioned specific embodiment is used for the present invention that explains, rather than limits the invention, and in the protection domain of spirit of the present invention and claim, any modification and change to the present invention makes all fall into protection scope of the present invention.
