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.
