Description
Technical field
The utility model relates to auto steerer, particularly a kind of left steering joint arm.
Background technology
Track arm is tie rod arm again, it is the afterbody force transferring part of steering transmission linkage, automobile in the process of moving, often to change its travel direction, usually when vehicle is when turning to, chaufeur applies a steering torque to steering handwheel, this moment passes through steering shaft, after deflector is amplified, this moment imports pitman arm into, then passes to the track arm on steering swivel and steering swivel by steering drag link, finally import wheel hub into, damage parts wheel deflected, as can be seen here the importance of track arm, once will cause heavy losses.
Utility model content
For solving the problem, the purpose of this utility model is to provide a kind of sound construction, easy to connect, internal stress is little, have the left steering of anti-high stretch capability joint arm.
For achieving the above object, the technical solution of the utility model:
A kind of left steering joint arm, comprise connected unit, connecting arm, mount pad, described connected unit is circular, centre has taper connection hole, connected unit side is provided with connecting arm, a small boss is provided with in connecting arm side, small boss is provided with tapped bore, one end of connecting arm is connected with mount pad, mount pad is semicircular arc, the centre of mount pad is provided with the first connecting portion and the second connecting portion, first connecting portion upper and lower surface is plane, the left and right sides is to intermediate projections shape, second connecting portion upper and lower surface is arc-shaped, front side is plane, rear side is the recessed dip plane of epirelief, mount pad two ends are provided with two round platforms, round platform is provided with installation through hole.
As preferably, described connected unit, connecting arm and mount pad are that iron and steel integral type is forged and formed.
As preferably, described tapped bore place is provided with round platform, is provided with counterbore at tapped bore another side.
As preferably, described installation through hole, tapped bore and connecting bore direction are orthogonal.
Beneficial conditions of the present utility model is: sound construction, easy to connect, internal stress is little, have anti-high stretch capability.
