Abstract

The utility model discloses an automobile tie rod end connecting structure, which comprises a ball pin (8), a small locking ring (9), a dustproof cover (10), a big locking ring (11), a ball shell (12), a ball seat (13) and a seal cover (14). The connecting structure is characterized in that a conical design concept is adopted at a swing angle position, and the connecting structure can effectivelyavoid direct friction between metals at a neck position caused by local limitation of large steering of a traditional automobile tie rod end when an automobile is in running, thereby being capable ofeffectively increasing steering smoothness and overall performance, improving local angles of large steering, avoiding direct friction between the ball pin (8) and the ball shell (12), performing buffering function in sharp steering, and achieving simple processing technology, safety, reliability, and easy realization of serialization and scale production.

Description

The automobile pull bar steering ball end linkage structure that a kind of angle range is bigger

Technical field

The utility model belongs to the design and fabrication technology field of motor turning facility, relates in particular to the linkage structure of automotive tie-rod end.

Background technique

Traditional automotive tie-rod end structure (as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4) is designed to the single swing by a small margin of swinging significantly and intersecting, and its inside is adopted the kinetic friction of metal and metal fully, and its base is iron-based base and equilibrant force spring.It is outside to adopt tight shell type and not to have the dust-proof cover of snap, and afterbody adopts the auxiliary oil-filling device of oil nozzle.Traditional automotive tie-rod end structure is by ball pin 1 being placed spherical shell 2, then ball seat 5 is put into, reinstall turriform spring 6, insert capping 7, use special-purpose riveting machine riveted good then, dust-proof cover 2 is inserted in again, promptly finishing.

Because traditional automotive tie-rod end complex structural designs, machining accuracy are not easy control, cost of production height.In rugged environment, enter water and sand easily, make its life of product shorter.Pivot angle and ball pin neck produce friction in the steering procedure, and be fragile.Friction generates heat between interior metal, makes the grease evaporation, often needs oiling, brings a lot of inconvenience to the Consumer.

The model utility content

Problem to be solved in the utility model has provided a kind of automotive tie-rod end structure that adopts the cone structure dust-proof cover, its objective is to avoid the friction of product pivot angle, enlarges product pivot angle scope.

To achieve these goals, the technological scheme taked of the utility model is:

This automotive tie-rod end structure comprises the ball pin, little collar, and dust-proof cover, big collar, spherical shell, ball seat and capping constitute, and wherein dust-proof cover adopts cone structure.Specifically be that the spherical shell of again it being packed into is put into capping, uses special-purpose riveting machine riveted good then, and the dust-proof cover that packages little collar is inserted on the spherical shell, puts big collar at last by the ball pin ball seat of packing into.

For making the utility model more perfect, technological scheme more detailed and concrete below also further having proposed realizes goal of the invention better, and improves novelty of the present utility model and creativeness to obtain best practical effect:

Dust-proof cover adopts big collar and little collar to be fixed on the ball pin, adds the ball seat that material is an acetal plastic, and the head of ball pin is placed in the ball seat, makes the head of ball pin be close to ball seat, and whole plate structure has then been adopted in capping.

Can avoid the pivot angle friction by the full-shape structure by the utility model automotive tie-rod end structure, the corner angle is bigger, and sealability is superior, and technology is simple, and cost of production is low.

Embodiment

As Fig. 5, Fig. 6, Fig. 7, shown in Figure 8, this the utility model belongs to automotive tie-rod end connecting structure by ball pin 8 ball seat 13 of packing into, the spherical shell 12 of again it being packed into, put into capping 14, use special-purpose riveting machine riveted good then, the dust-proof cover 10 that packages little collar is inserted on the spherical shell 12, puts big collar at last.Dust-proof cover 10 is designed to cone structure, has avoided the pivot angle friction, and the corner angle is bigger, and dust-proof cover 10 is fixing by the lesser calorie circle 9 and the big collar 11 at two ends again, thereby minimizing water and silt enter the damage that product inside causes, and have improved the sealability of product.Added ball seat 13 in spherical shell 12 and capping 14 inboards, made ball seat be close to bulb, and ball seat 13 adopts acetal plastics to constitute, thereby lower interior metal and metal friction, need not oiling, also therefore bottom cover 14 can be removed oil nozzle then adopt whole plate structure.

The above is preferred embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model.
