Description
Technical field
The invention belongs to steering technical field, particularly relates to a kind of single tierod assembly.
Background technology
Steering system is the mechanism for keeping or changing vehicle traveling direction, as shown in figure 1, being travelled in motor turning
When, driver turn steering wheel 02, diverted device 01, Drag link 03, curved boom 08, left steering joint arm 05, right turn joint arm 06, horizontal stroke
Pull bar 04 drives deflecting roller to deflect, in order to ensure coordinated angle relation between each deflecting roller, it is necessary to by drag link, left steering
Joint arm and right turn joint arm form steering trapezium to coordinate the motion of left and right turn wheel.
Drag link 04 is connected with left and right knuckle arm respectively by ball pin 07, and left steering joint arm and right turn joint arm are relative
Face is symmetrical in vehicle, forms tie rod linkage, therefore claim steering trapezium.Change the length of drag link with regard to the shape of steering trapezium can be changed
Shape, so as to change the prenex size of wheel, also change the rapport of left and right turn wheel.
It is divided into Integral steering trapezoidal mechanism, divided steering linkage according to drag link and steering gear annexation.Independent suspension
Divided steering linkage is then used, the drag link of left and right two is connected with steering gear.And rigid axle suspension uses Integral steering more
Trapezoidal, an only drag link, single tierod assembly includes ball pin, left ball pin seat, right ball pin seat and drag link etc..
Because the toe-in of pivoted wheels on vehicle directly affects the straight trip and wheel alignment of vehicle traveling, so being installed in vehicle
It must reach rational toeing-in with the relative position of left and right ball pin by adjusting the end of drag link with during maintenance.
The connected mode of drag link and ball pin is a lot, and connected mode not only determines complexity during prenex adjustment, and
Influence the reliability after adjustment.
A kind of single tierod assembly of prior art is as shown in Fig. 2 by ball pin 1, left ball pin seat 2, drag link
3rd, right ball pin seat 4 forms, and drag link one end is left outside screw thread, and the other end is right external screw thread, is fixed by bolt and nut 5.
All nuts in the left and right sides are unclamped when adjusting prenex, drag link is rotated and is adjusted, will be by rule after having adjusted
Determine torque and tighten all nuts, installation and maintenance are all cumbersome, operation is laborious, must could rotate horizontal drawing with special spanner
Bar.
Another single tierod assembly of prior art, as shown in figure 3, by ball pin 1, left ball pin seat 2, horizontal drawing
Bar 3, right ball pin seat 4 form, and drag link one end is left inside screw thread, and the other end is right internal thread, is fixed by locking nut 6.
The locking nut of the left and right sides is unclamped when adjusting prenex, drag link is rotated and is adjusted, will be by rule after having adjusted
Determine torque and tighten locking nut, installation and maintenance are all cumbersome, it is laborious to operate, and toe-in adjustment is cumbersome and difficult；Locking
Due to thread pitch and deformation, prenex variations a small amount of therewith during nut check；Poor reliability, time length easily loosen.
