Abstract
The utility model aims to provide a single-chip control arm with a large single-riveting ball head so as to improve the reliability of a ball head hinge. In order to realize the utility model, the single-chip control arm with the large single-riveting ball head comprises a single-chip body and a ball hinge and is characterized in that the ball hinge is a lug-free ball hinge, the lug-free ball hinge is a ball hinge assembly and comprises a ball head pin, a ball head seat, a ball bowl and a jacket, the ball bowl comprises a ball head part of the ball head pin and is positioned between the ball head part and the ball head seat, the jacket is sleeved at an opening side of the ball head seat and outside the ball head pin, and the ball head seat is pressed into a single-chip body hole so that the ball head seat and the single-chip body hole are riveted by extruding a joint face.
Description
Technical field
The utility model relates to the automotive suspension Control arm.
Background technology
As shown in Figure 1, McPherson suspension uses before the punching press welding Control arm to be welded with sleeve for two or monolithic up and down, and is mostly that with steering swivel bonded assembly bulb hinge the big shape forging bulb of band ear forms through 2～3 bolts or rivet connection.Bulb hinge volume is big, connect screw or rivet is prone to lose efficacy.
The utility model content
The purpose of the utility model is to provide a kind of monolithic band big single riveted joint bulb Control arm, to improve the reliability of bulb hinge.
The big single riveted joint bulb Control arm of monolithic band for realizing said purpose comprises monolithic body and spherical hinge, is characterized in; This spherical hinge is the earless spherical hinge, and this earless spherical hinge is a spherical hinge assembly, comprises ball end, ball cap, ball bowl and sheath; The ball bowl coats the ball head of ball end; Between ball head and ball cap, sheath is enclosed within the open side of ball cap and the outside of ball end, and ball cap is pressed in the monolithic body apertures so that the two is through the riveted joint of extruding face of joint.
The Control arm of the utility model adopts the structure of a kind of monolithic body and the riveted joint of earless spherical hinge, has saved the space, has reduced weight, has practiced thrift bulb heavy forging cost, has save spherical hinge and body coupled fasteners.
For most of McPherson suspensions, the utility model is compared with punching press welded structure up and down before, only needs to drop into 2 width of cloth forming moulds, does not have the welding distortion.
Adopted the bulb hinge assembly that can provide together separately, be assembled on the monolithic body and only need be pressed into shaping and get final product, technology is simple and convenient; Compare with big shape forging bulb hinge installation; Annex is few, connects more reliably, need not design verification fastener and moment of torsion etc. thereof again.
Middle-size and small-size passenger-car chassis inner space increases behind the big single riveted joint face bulb Control arm of employing monolithic band, complete vehicle weight reduces, structural manufacturing process is simple, die cost descends more, good reliability.This has satisfied technology, reliability requirement and the cost requirement of economic vehicle well, must form the application market that possesses competitive power.
Description of drawings
Fig. 1 is the structural representation of existing Control arm.
Fig. 2 is that the axle of the big single riveted joint bulb Control arm of the monolithic band of the utility model is surveyed view.
Fig. 3 is the section-drawing along A-A line among Fig. 2.
The specific embodiment
As shown in Figures 2 and 3, the big single riveted joint bulb Control arm of monolithic band comprises monolithic body 1 and earless spherical hinge 2.Earless spherical hinge 2 is a spherical hinge assembly; It comprises ball end 21, ball cap 22, ball bowl 24 and sheath 23; Ball bowl 24 coats the ball head of ball end 21, and between ball head and ball cap 22, sheath 23 is enclosed within the open side of ball cap 22 and the outside of ball end 21.Ball cap 22 is pressed in monolithic body 1 hole so that the two is through 11 riveted joints of extruding face of joint.
Claims (1)
