Abstract

The utility model discloses an automobile steering knuckle which comprises a bearing journal, a flange and a yoke. The automobile steering knuckle is characterized in that the bearing journal is a stepped shaft. The yoke consists of an upper lug and a lower lug both integrally fixed to the flange. The stepped shaft is provided with an outer cylindrical face, a conical face and a threaded face sequentially from outside to inside. The automobile steering knuckle is easier to manufacture and cost-saving. By the aid of a die designed according to a 630T pre-forging procedure graph, precision blanking can be achieved, and production benefits can be increased.

Description

A kind of spindle

Technical field

The utility model relates to a kind of auto parts and components, belongs to mechanical equipment technical field, is specially a kind of spindle.

Background technology

Steering swivel is one of vital parts on the steering axle of automobile, and it can make vehicle steadily go and the sensitive travel direction that transmits, and the effect of steering swivel is to bear automotive front load, and supporting also drives front-wheel and rotates and make motor turning around stub.Under motoring condition, steering swivel is bearing changeable impact load, therefore, requires it to have very high intensity.

Existing spindle mainly is made up of bearing spigot, flange and crotch three parts, and steering swivel is connected with wheel steering shaft through bearing spigot, and links to each other with brake system through the drg mounting hole on the flange.Because the existing present general weight of steering swivel is bigger, therefore difficulty is bigger when fabrication and processing, and the precision after the moulding is wayward, and this causes product quality lower.

The utility model content

To above-mentioned deficiency of the prior art, the purpose of the utility model is to solve existing spindle because own wt causes the big problem of difficulty of processing greatly, and provides a kind of easy to process, the higher spindle of precision after the moulding.

The technical scheme of the utility model: a kind of spindle, comprise bearing spigot, flange and crotch, it is characterized in that said bearing spigot is a stepped shaft, said crotch is to be made up of last ear that is solidified as a whole with flange and following ear.

Further technical scheme, said stepped shaft ecto-entad is followed successively by external cylindrical surface, circular conical surface and flat of thread.

With respect to prior art, the utlity model has following beneficial effect:

1, the fabrication and processing difficulty reduces: after the steering swivel of the utility model adopts shearing blanking; Forge and press plastic forming with friction press; The moulding that originally needs 1000 ton forces to accomplish only needs 630 ton forces can accomplish moulding now, has significantly reduced manufacture difficulty.

2, practiced thrift cost,, can realize accurate blanking, thereby save raw material, also helped improving productivity effect through design stepped shaft and the mold design of 630T electric screw press blocking.

Description of drawings

Fig. 1 is the front view of the utility model spindle;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the upward view of Fig. 1.

Among the figure, 1-bearing spigot, 2-flange, 3-crotch, 31-upward ears, 32-following ear.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.

Like Fig. 1, Fig. 2 and shown in Figure 3, a kind of spindle comprises bearing spigot 1, flange 2 and crotch 3, and said bearing spigot 1 is stepped shaft and the front end of being located at flange 2, and this stepped shaft ecto-entad is followed successively by external cylindrical surface, circular conical surface and flat of thread.Crotch 3 is to be made up of last ear that is solidified as a whole with flange 2 31 and following ear 32, and last ear 31 and following ear 32 are located at the both sides up and down of flange 2 rear ends respectively.

When making steering swivel; Earlier through 500T blanking machine shearing blanking; By the heating of 500Kw induction furnace, use 315T punch press jumping-up subsequently, and process blank again by the 250Kg pneumatic hammer; Then successively behind 630T electric screw press blocking and 630T electric screw press finish-forging, by the moulding of 100T punch press hot trim.

Need to prove at last; Above embodiment is only in order to technical scheme but not the restriction technologies scheme of explanation the utility model; Although the applicant specifies the utility model with reference to preferred embodiment, those of ordinary skill in the art should be appreciated that those modifications that technical scheme of the utility model is carried out perhaps are equal to replacement; And do not break away from the aim and the scope of present technique scheme, all should be encompassed in the middle of the claim scope of the utility model.

Claims

1. spindle; Comprise bearing spigot (1), flange (2) and crotch (3); It is characterized in that said bearing spigot (1) is a stepped shaft, said crotch (3) is to be made up of last ear (31) that is solidified as a whole with flange (2) and following ear (32).

2. spindle according to claim 1 is characterized in that, said stepped shaft ecto-entad is followed successively by external cylindrical surface, circular conical surface and flat of thread.
