One end be located at the second ball cup 140 and can opposite second ball cup 140 rotate, the other end of the second ball stud 142 is used to connect
The parts such as subsequent pitman arm are connect, to transmit the go to action from ball-and-nut steering gear.
The working principle and the course of work of motor turning pull rod 100 are as follows:
When needing to adjust ball-and-nut steering gear position, the fastening nut as fastener 134 is unclamped first.Secondly, by
It can be rotated relative to the first ball cup 110 in the first ball stud 120, be approximately perpendicular to bar body 130 axially using spanner
First ball stud of plane internal rotation 120 in direction, at this point, 110 position of the first ball cup is motionless.Due to the first ball stud 120 with
Bar body 130 is threadedly coupled, therefore in rotary course, the first ball stud 120 can be with respect to bar body 130 along pull rod
The axial direction movement of ontology 130 is with close or separate bar body 130, to change the first end of the first ball stud 120
The distance between 122 and bar body 130.Since the first end 122 of the first ball stud 120 is connected to the first ball cup 110, i.e.,
Change the distance between the first ball cup 110 and the second ball cup 140, that is, changes pull rod entire length.At this point, the first bulb
110 positions of seat change with the change of pull rod entire length, since the first ball cup 110 is fixed on ball-and-nut steering gear rocker arm
200, so that ball-and-nut steering gear rocker arm 200 be driven to rotate, until ball-and-nut steering gear position arrival desired location, stop rotating
First ball stud 120 and the relative position that the first ball stud 120 and bar body 130 is locked using fastener 134, are so far completed
The adjustment process of entire ball-and-nut steering gear.
Relative to conventional steering pull rod, motor turning pull rod 100 is by exchanging the first ball stud 120 and the first ball cup
110 relative position makes the first ball cup 110 be fixedly connected on ball-and-nut steering gear rocker arm 200, the connection of the first ball stud 120
It can be rotated relative to the first ball cup 110 in bar body 130, while by the first ball stud 120, not only meet automobile and turn
Not having to disassembly pull rod to requiring, and when adjusting to ball-and-nut steering gear or steering front wheel positioning, adjusting yoke length is convenient,
Improve debugging efficiency when installation or maintenance.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
