Abstract

The utility model relates to a steering ball joint which belongs to the class of the steering engines of motor vehicles. The steering ball joint is composed of a ball head seat frame, a sleeve in the frame, and a vertical shaft in the sleeve. The lower end of the vertical shaft is provided with a half ball head whose top is provided with a cylindrical section and is provided with a needle roller in an attaching mode, and the outside of the needle roller is provided with a needle roller outer sleeve. A half ball head seat is arranged under the half ball head at the lower end of the vertical shaft, a supporting tray is arranged under the ball head seat, and a spring whose bottom face is provided with a spring seat is arranged under the supporting tray. The back face of the spring seat is sealed and blocked by a clamp spring which is arranged in the bottom opening of the ball head seat frame. By adopting the needle roller structure, the utility model has the characteristics of small frictional force, high durability, and flexible rotation.

Description

The steering ball joint

The utility model belongs to motor turning machine class.

Motor Vehicle must rely on the turning to of flexibility and reliability of steering box under steam, just can guarantee the safety of driving a vehicle, and the steering box steering knuckle of existing Motor Vehicle is made up of the ball-head cover in bulb mounting, the bulb mounting, vertical shaft in the ball-head cover.The bulb of vertical shaft lower end forms ball pivot and rotates and to carry out transmission of power and turn in ball-head cover, the problem of this spherical hinge structure is: form sliding friction between bulb and the ball-head cover, frictional force is big, and wearing and tearing are very fast, and it is dumb to make steering equipment rotate effort.

The purpose of this utility model is: a kind of laborsaving joint of steering ball flexibly that turns to is provided.

The technical solution of the utility model is: with by the cover in bulb mounting, the bulb mounting, the steering knuckle that vertical shaft in the cover is formed is the basis, what adopted the vertical shaft lower end is hemispherical head, above the hemispherical head be cylindrical section and dress with needle roller, the needle roller outside is the needle roller overcoat, a hemisphere headstock is arranged below the hemispherical head of vertical shaft lower end, a pallet is arranged below the hemisphere headstock, a spring is arranged below the pallet, and there is a spring seat spring bottom surface, the spring seat back side by the bulb frame at the bottom of jump ring block in the mouth.

Steering ball joint of the present utility model has the needle roller structure owing to adopt, so turn to frictional force little, wear-resistant, steering equipment rotates laborsaving and good effect flexibly.

Accompanying drawing is a structural representation of the present utility model.

Drawing explanation and embodiment are described below: 4 is bulb mountings among the figure, vertical shaft 1 lower end in ball seat frame 4 is original to be whole bulb, that adopt vertical shaft of the present utility model lower end is hemispherical head A, is that cylindrical section and dress have needle roller 8 above the hemispherical head A, and the needle roller outside is a needle roller overcoat 3; A hemisphere headstock 10 is arranged below the hemispherical head A of vertical shaft 1 lower end, a pallet 11 is arranged below the hemisphere headstock 10, a spring 5 is arranged below the pallet 11, a spring seat 13 is arranged below the spring 5, the back side of spring seat 13 is by jump ring 12 block in 4 end of the bulb mounting mouth.Like this, vertical shaft 1 is subjected to the rotation of steering force, adopts the rolling between needle roller 8 and the needle roller overcoat 3, has frictional force little, and is wear-resistant, the rotation flexible characteristic, and 6 is cotter pins among the figure, clamp nut 7 is locked in the upper end of vertical shaft 1 by cotter pin 6, rotates with operating mechanism; The 9th, be screwedly mounted on the grease nipple on the bulb mounting 4, the 2nd, cover on the dustproof glue cover on the bulb mounting 4.

Claims
