The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, ecp steering hardware of the present utility model, comprise Transmission 1, electric device 2, guide-localization screw mandrel 3, setscrew nut 4, power-assisted cylinder 5 and frame 6, Transmission 1 is sheathed on the frame 6 on the set guide rod 61, power-assisted cylinder 5 is arranged in parallel with guide rod 61 and links to each other with Transmission 1, the mouth of electric device 2 links to each other with guide-localization screw mandrel 3, and setscrew nut 4 is installed on the guide-localization screw mandrel 3 and with Transmission 1 and is rigidly connected.Electric device 2 comprises motor 21 and retarder 22.Adopt power-assisted cylinder 5 and guide-localization screw mandrel 3 to realize that turning to control, power-assisted cylinder 5 to provide turns to auxiliary force, alleviate labor intensity of operating personnel, can not produce problem of environment pollution caused such as liquid oil leakage simultaneously; Guide-localization screw mandrel 3 can be realized accurate location, can control the size of steering angle by the rotating cycle of electric device 2 control guide-localization screw mandrels 3.Transmission 1 is provided with tooth bar 7, is equiped with on the frame 6 and follows bar 8, follows to be equiped with on the bar 8 with tooth bar 7 ingears and follows gear 9, follows bar 8 to link to each other with operating handle 11 by deflecting bar 10.Follow bar 8, deflecting bar 10 and operating handle 11 to link to each other by universal-joint 14, operating handle 11 links to each other with frame 6 by spring 16.Follow gear 9 to be provided with two travel position switches 12, follow bar 8 to be provided with driving lever 15, the end of driving lever 15 is between two travel position switches 12.By following gear 9, following bar 8 and installing driving lever 15 and travel position switch 12 thereon, the ecp steering hardware is kept at an angle under the unmodified state continues to turn to, and the convenient handle that adopts is operated.Be hinged with steering track rod 13 on the Transmission 1, steering track rod 13 can link to each other with actuating units such as wheels.
Below in conjunction with the ecp steering hardware that is installed on the automobile principle of work of the present utility model is described: when just beginning, operating handle 11 is kept upright under spring 16 effects, follow that two travel position switches 12 are in off-state on the gear 9, circuit is disconnected, cylinder is not worked, and automobile positive travels.When automobile needs left steering, chaufeur promotes operating handle 11 deflection left, operating handle 11 drives deflecting bar 10 and follows bar 8 left-hand revolution certain angles by universal-joint 14, thereby follow driving lever 15 on the bar 8 to make the left side contacting of the travel position switch of following on the gear 9 12, in contacting, motor 21 must be established the beginning clockwise direction by cable and rotate, drive 3 rotations of guide-localization screw mandrel, setscrew nut 4 has the trend that is moved to the left, power-assisted cylinder 5 rod chambers lead to high pressure gas simultaneously, rodless cavity leads to atmosphere, make that piston rod shrinks in the power-assisted cylinder 5 left, driving Transmission 1 is moved to the left, and drive is moved to the left with guide-localization screw mandrel 3 with Transmission 1 rigidly connected setscrew nut 4, make with Transmission 1 pivotally attached steering track rod 13 to be moved to the left, thereby drive the wheel left-handed turning, the degree of wheel left-handed turning depends on the amplitude of oscillation of operating handle 11.Transmission 1 drives connected tooth bar 7 and moves to left when moving to left, follow the rotation of gear 9 anticlockwise directions thereby make, when following gear 9 anglecs of rotation and following bar 8 anglecs of rotation consistent, driving lever 15 breaks away from travel position switch 12, makes 12 outages of travel position switch, and power-assisted cylinder 5 two ends lead to atmosphere, motor 21 outages, guide-localization screw mandrel 3 and setscrew nut 4 lockings, wheel stops deflection, and keeps existing steering angle.When chaufeur no longer needs to turn to, decontrol operating handle 11, operating handle 11 meetings self-aligning under the effect of spring 16, thereby follow bar just and by driving lever 15 the travel position switch 12 right sides electric shock of following on the gear 9 being connected 8 times, power-assisted cylinder 5 rodless cavities communicate with high pressure gas, motor 21 gets electric left-hand revolution, makes wheel deflection to the right, up to just returning.Right steering is just in time opposite with the process of left steering.
