The specific embodiment
As Fig. 1, crank-connecting rod mechanical steering mechanism shown in 2 comprises and turns to handgrip 1, bracket 2, bottom bracket 3, steering shaft 4, steering-column tube 5, steering-column tube bearing 6, crank 7, turning joint 8, connecting rod 9, spherical linkage 10, deflector 11, intermediate rod 14, steering swivel 15, turn to handgrip 1 by bracket 2, bottom bracket 3 is connected with steering shaft 4, steering shaft 4 and crank 7, turning joint 8, connecting rod 9, spherical linkage 10, deflector 11 connects successively, steering shaft 4 is outer to be provided with steering-column tube 5 and by turning to lining to be connected with taper roller, the steering-column tube 5 outer steering-column tube bearings 6 that are provided with, deflector 11 comprises: turn to bar 12, turn to bar shell 13, end cap 16, trimming screw 17, jam nut 18, pad 19, spring 20, oil sealing 21, briquetting 22, spring 20 will turn to bar 12 to be pressed against by briquetting 22 and turn in the bar shell 13, the pre-police strength of spring 20 is adjusted with trimming screw 17, turn to and be fixed with spherical linkage 10 on the bar 12, spherical linkage 10 is connected with connecting rod 9, turn to bar 12 outer being provided with to turn to bar shell 13, have the spherical linkage chute on the bar shell 13 turning to, turn to bar 12 1 ends to be connected with steering swivel 15 through intermediate rod 14, turn to bar 12 other ends to be connected steering-column tube bearing 6 with steering swivel 15 through intermediate rod 14, turn to bar shell 13 to connect to ground.
Captive joint between described crank 7 and the steering shaft 4, adopt turning joint 8 between crank 7 and the connecting rod 9, connecting rod 9 with turn to employing spherical linkage 10 between the bar 12.
As shown in Figure 3, intermediate rod 14 two ends and turn between bar 12, the steering swivel 15 and adopt spherical linkage.The metal joint that intermediate rod 14 two ends are provided with, right-hand member is processed with negative thread, is used for being connected with the outside thread of the Rod end at intermediate rod 14 middle parts, simultaneously its locus when installing of scalable; Left end is processed with inner arc surface, to realize intermediate rod 14 and spherical secondary connection that turns between bar 12, the steering swivel 15.
Working process of the present invention is as follows:
Turn to handgrip 1 to be connected with steering shaft 4 by bracket 2, bottom bracket 3, steering shaft 4 is bearing in the steering-column tube 5 by turning to lining and taper roller, the front end of crank 7 is captiveed joint with steering shaft 4 by screw thread, jam nut etc., adopts turning joint 8 between rear end and the connecting rod 9.Owing to require steering shaft to be in tilted layout, for the ease of adjusting the installation site, the other end of connecting rod 9 and turn between the bar 12 and adopt spherical linkage.Turn to bar 12 to be installed in and turn in the bar shell 13, turn to bar shell 13 as the supporting chute that turns to bar 12 sway.Turn to bar shell 13 to be fixedly mounted on the vehicle frame, and turn to and be processed with one section open slot on the bar shell 13, for the ball end sway.The two ends of intermediate rod 14 adopt spherical linkage to be connected with turning to bar 12, steering swivel 15 respectively, steering-column tube bearing 6 with turn to bar shell 13 to be fixedly connected on the vehicle frame.
Turn to handgrip 1 left behind (or to the right) rotating certain angle θ, because steering shaft 4 is captiveed joint with crank 7, piston crank mechanism is converted into the horizontal displacement S that turns to bar 12 with the angle θ of steering shaft 4, turn to front end that bar 12 drives intermediate rods 14 to the right (or left) corresponding displacement takes place.The lower end traction left and right wheels steering swivel 15 of intermediate rod 14 makes it inclined to one side give part of a turn, thereby realizes turning to of car load.
