Abstract
The utility model discloses a drag link joint assembly of an automobile. The drag link joint assembly comprises a joint body, wherein a ball stud is arranged inside the joint body; the ball of the ball stud is wrapped between an upper ball bowl and a lower ball bowl; a spring is arranged at the bottom of the lower ball bowl; a rear cover is arranged outside the spring; the rear cover and the lower end of the joint body are integrally connected; a dustproof hood is arranged at the upper part of the upper ball bowl; the dustproof hood covers above the joint body; the ball stud passes through the dustproof hood and is provided with a connecting head; oil grooves are arranged inside the ball planes of the upper and lower ball bowls; and oil injection nozzles are arranged on the side wall corresponding to the joint body. When being used, the ball head of the ball stud is wrapped between the upper and lower ball bowls and move freely, the axial and radial gaps between the ball stud and the ball bowls are reduced, the friction is reduced, and the service life is greatly prolonged; a drag link joint rear cover is prevented from bulging up, so that the phenomenon that the ball bowls are stuck inside the ball is prevented; and meanwhile, when the automobile runs, the ball stud is unlikely to move disorderly, so that a driver feels stable in driving and easy to control the direction.
Description
Technical field
The utility model relates to auto parts and components, specifically a kind of automobile straight rod head assembly.
Background technique
The Hyundai Motor project organization is more and more compacter, the shared space of automobile straight rod assembly is more and more less, the size of joint directly affects the design of car load, according to the needs of car load development, a kind of polyoxymethylene of using occurred as the Drag link fittings body assembly of ball bowl, but dried up owing to butter appears in its non-maintaining structure after a period of time, the ball pin wearing and tearing are accelerated, looseness, and because its tightness requires by force, bonnet is often by defectives such as pressure jack-up.
Summary of the invention
The purpose of this utility model be to provide a kind of rational in infrastructure, satisfy a kind of Drag link connector assembly that the automobile fittings body is exercised standard.
For this reason, the technical solution of the utility model is, a kind of automobile straight rod head assembly, comprise fittings body, it is characterized in that: be provided with ball stud in fittings body, the bulb of ball stud is rolled between the upper and lower ball bowl, is provided with spring in the bottom of lower ball bowl, the outside of spring is provided with bonnet, and bonnet and fittings body lower end are connected; The top of upper ball bowl is provided with dust-proof cover, and dust-proof cover covers on fittings body top, and ball stud passes dust-proof cover and is provided with connecting head.
Improvement to such scheme is: be provided with oil groove in the sphere of upper and lower ball bowl, and be provided with pump nozzle at the sidewall of the fittings body of upper and lower ball bowl correspondence.
Beneficial effect:
The utility model in use bulb of ball stud is rolled in voluntary activity between the upper and lower ball bowl, and the axial and radial clearance between ball stud and the ball bowl reduces, and wearing and tearing reduce, and greatly improve working life; Prevent Drag link joint bonnet protuberance, ball bowl stuck phenomenon in spheroid of having eliminated, simultaneously, vehicle in motion ball pin is difficult for play, and the pilot control feel is steady, and direction is grasped easily.
In the sphere of upper and lower ball bowl, be provided with oil groove, and be provided with pump nozzle at the sidewall of the fittings body of upper and lower ball bowl correspondence.To arrange in order to guarantee lubricated between ball stud and the ball bowl.
