Detailed description of the invention
See figures.1.and.2, a kind of bearing circle of the present utility model is biased steering hardware, comprise the bearing circle 21, steering wheel tubular pipe 22, universal-joint 23, universal-joint connecting rod 24, universal-joint 23, biased steering assembly 25 and the front component 26 that connect according to this, bearing circle 21 is arranged on steering wheel tubular pipe 22, by universal-joint 23 universal-joint connecting rod 24, universal-joint connecting rod 24 is connected with biased steering assembly 25 by universal-joint 23, and biased steering assembly 25 is arranged with front component 26.
Described biased steering assembly 25 is fixed on and is provided with on the permanent seat 1 of three bearing seats, described biased steering assembly 25 comprises and is contained in pinion shaft 2 in three bearing seats and miniature gears 3, middle gear axle 5 and middle gear 4, Large Gear Shaft During 7 and big gear wheel 6 successively, miniature gears 3, middle gear 4 and big gear wheel 6 engage successively, and described miniature gears 3, middle gear 4 and big gear wheel 6 are in same plane upper driving.The center of described three bearing seats is on same straight line.Pinion shaft 2, middle gear axle 5 and be provided with antifriction-bearing box between Large Gear Shaft During 7 and bearing seat, appropriate location in big gear wheel 6 is also provided with two spacing pivot pins 8, permanent seat 1 is provided with and coordinates with spacing pivot pin 8 the spacing adapter plate 31 limiting big gear wheel 6 rotational angle, big gear wheel 6 and front component 26 are connected and fixed.
Described big gear wheel 6 is provided with spacing hole, and described spacing pivot pin 8 is fixed in this spacing hole, the steering angle of restriction vehicle.Further, described big gear wheel 6 is provided with four spacing holes and two spacing pivot pins, 8, two spacing pivot pins 8 are fixed in the Liang Ge spacing hole in big gear wheel 6, the left and right turn angle of corresponding restriction vehicle, two other spacing hole reserves for subsequent use.Because in general front tyre steering angle is less than 180 degree, namely under the normal condition used, the tooth of big gear wheel 6 only has fewer than half to participate in gear motion.We have reserved one group the position of the Kong Qi symmetry of mounting limit bearing pin in big gear wheel 6, when the tooth of big gear wheel 6 damages due to reasons such as wearing and tearing, we can revolve turnback big gear wheel 6 and install, and use second half work never participating in gear motion.The design of this symmetry, improves the service life of big gear wheel 6 exponentially, reduces the maintenance cost of product.
In order to prevent dust accumulation from affecting turning function, bottom described biased steering assembly 25, being provided with cover of dust, below cover of dust, having dust ring with the adapter shaft overcoat be connected of front component 26.
In order to realize damping, certain protective effect is played to steering hardware simultaneously, described front component 26 is provided with damping spring.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention but not to be limited, although with reference to preferred embodiment to invention has been detailed description, but those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of the technical program, it all should be encompassed in right of the present invention.
