Description
Technical field
The utility model belongs to the automobile steering system technical field, is specifically related to a kind of outer bulb assembly of deflector of automobile steering system.
Background technology
When estimating vehicle handling stability and traveling comfort, the performance of steering swivel system is one of object of paying close attention to of people, is presented as the size of chaufeur hand-power, the smooth and easy and continuity of feel; And one of condition that guarantees above performance is exactly that drive gap can not be arranged between each parts of steering swivel system, and the reason that produces drive gap mostly is drive disk assembly motion vice division chief poor sealing, so that foreign matter enters, has caused the premature wear between kinematic pair.Outside deflector in the bulb assembly outside the deflector bulb seal closure be one of vitals of realizing the sealing of drive disk assembly kinematic pair, referring to Fig. 3.And present dust boot utilizes dimensional fits to realize sealing usually, because dust boot is elastomeric material, easily distortion in the bulb swing process that cooperates with it, can produce the gap with the fitting surface of bulb, thereby cause the impurity such as dust, silt to enter ball-joint inside, accelerate the rate of wear, produced movement clearance between parts, finally reduced the driver comfort of car load.
The utility model content
In order to solve the premature wear of the outer bulb of deflector, make dust boot have better sealing function, the utility model provides a kind of outer bulb assembly of deflector with multi-sealing structure by structural development.
Concrete structural development technical scheme is as follows:
The outer bulb assembly of deflector with multi-sealing structure comprises that an end is provided with the outer ball end 3 of bulb, the bulb of outer ball end 3 is positioned at ball cap, be provided with lining 6 between the bulb of outer ball end 3 and the ball cap, the bottom cooperation of ball cap is provided with end cap 7, and the top cooperation of ball cap is provided with dust boot 5; Described dust boot 5 is cannula-like, the upper end is portlet, the lower end is large port, footpath, middle part convex, the radial fit face of described portlet cooperates with the shank 31 of outer ball end 3, and the portlet radial fit face of dust boot 5 is provided with three road lip annular grooves 53, and described large port is set in the top of ball cap, it is characterized in that: the portlet inner radial of described dust boot 5 is provided with endless metal skeleton 52, and the axial outer end face of described portlet is provided with five road lip annular grooves 51; With cooperate the bulge loop 32 that is provided with evagination on the shaft of the outer ball end 3 of the axial inner ends face cooperation place of described portlet.
The top of described endless metal skeleton 52 is provided with to the flanging that turns up.
The upper end anchor ring of the bulge loop 32 on described outer ball end 3 shanks is the plane, and the lower end anchor ring is the cambered surface that is connected with the shaft smooth transition.
The utility model with the steering swivel registration interface designs five road annular lip, increased metallic framework in the inside, cooperation place with bulb, and boss has been designed in the shank corresponding position of ball end outside, with the steering swivel attachment face dust boot lip is fixed; Can realize better that by above structural development dust boot is to the sealing of bulb inside.
