The side of narrow portion and the side of wide portion are cylindrical sides, and because the side of draw-in bar housing narrow portion is level and smooth, in the time that car load assembles, iron gasket there will be the phenomenons such as assembling is insecure, meeting is loosening while connection with draw-in bar housing.
Meanwhile, the telescopic of prior art, small end seal and large end part seal mouth are all straight designs. Small end seal, due to insufficient strength, can cave in and enter bellows portion; In addition, the sealing effectiveness of small end seal and large end part seal mouth has much room for improvement.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the utility model provides a kind of newly-designed draw-in bar housing.
The technical solution adopted in the utility model is:
A kind of motor turning rod assembly, comprise draw-in bar housing, draw-in bar, tie rod assembly and drag link telescopic, drag link telescopic comprises small end seal, middle part radiation fins and large end part seal mouth, the neck outer wall place being connected with middle part radiation fins at small end seal is evenly provided with several reinforcements, is evenly interval with small end sealed muscle on the inwall of small end seal.
Further, on the inwall of described large end part seal mouth, be evenly interval with large end part seal muscle.
Small end sealed muscle cross section is the circular arc of radius 0.6mm, the high 0.3mm of circular arc; Large end part seal muscle cross section is the circular arc of radius 1mm, the high 0.3mm of circular arc.
Further, small end is spaced apart the cross-sectional width of small end sealed muscle; Large end part interval is the cross-sectional width of large end part seal muscle.
Further, the outer wall of described large end part seal mouth is provided with mould reinforcement.
Further, draw-in bar housing comprises ball seat and joint pin, and the inner chamber of ball seat is spherical inner chamber, and spherical inner chamber is connected with the bulb of draw-in bar, and ball seat bottom is provided with joint pin, and the bottom outer wall of ball seat is provided with pair of flanges, forms pad holddown groove between pair of flanges.
Further, flange and ball seat global formation, the groove center line of pad holddown groove is vertical with draw-in bar housing axis.
Further, the corner at described flange two ends is obtuse angle.
Further, the corner at described flange two ends is 160 degree.
The utility model beneficial effect is obvious: in the time that car load assembles, circular iron gasket upset is rear and the riveted joint of draw-in bar housing is more firm, can improve the stability of assembling, improves the safety coefficient of automobile and the service life of prolongation automobile.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further, but scope of the present utility model is not limited to following embodiment.
As shown in the figure, a kind of motor turning rod assembly, comprise draw-in bar housing, draw-in bar 6, tie rod assembly 3 and drag link telescopic 5, draw-in bar housing comprises ball seat 1 and joint pin, the inner chamber of ball seat 1 is spherical inner chamber, and spherical inner chamber is connected with the bulb of draw-in bar, and ball seat 1 bottom is provided with joint pin, the corner that the bottom outer wall of ball seat 1 is provided with a pair of two ends is the flange 2 at 160 degree obtuse angles, flange 2 and ball seat 1 global formation.
In track rod, draw-in bar 6 is placed in drag link telescopic 5; Junction at drag link telescopic 5 with tie rod assembly 3, is fixed on drag link telescopic 5 on tie rod assembly 3 by flexible collar 4.
