Please refer to fig. 1-2, which are an automobile horn structure for effectively enhancing local structural strength, comprising a horn body 1 and a reinforcing block 2 arranged in the body 1, wherein the horn body 1 and the reinforcing block 2 form an integral blank through a casting process, and a finished horn product is formed through machining after casting is completed, as shown in fig. 2. The utility model provides a front and rear sheep horn structure, which comprises a sheep horn body 1 and a reinforcing block 2, wherein the reinforcing block 2 and the sheep horn body 1 are cast into an integral sheep horn blank, and then machining the blank is finished through machining, so that a sheep horn finished product is finally formed.

The reinforcing block 2 needs to be capable of bearing larger stress caused by interference fit of key parts, and the material emphasis of the reinforcing block is higher than that of the casting material of the claw body 1, and high-strength steel or alloy materials can be selected. The reinforcing blocks 2 may be prefabricated at the key locations of the sheep's horn, reinforcing the structural strength at the key locations, typically at the steering arms, kingpin arms, bearing holes. The reinforcing block 2 and the claw body 1 need to be cast into a whole claw blank, the reinforcing block needs to be prevented from being reversely stressed to be separated during casting, and an anti-falling mechanism needs to be arranged between the reinforcing block 2 and the claw body 1, such as a flange surface is added on the reinforcing block 2.

When in actual use, the steering taper pin and the sheep horn are locked through interference fit, the taper pin applies larger pressure to the wall of the sheep horn taper hole, according to the utility model, the reinforcing block with higher material strength is arranged between the sheep horn body 1 and the taper pin, and the reinforcing block 2 bears the pressure exerted by the taper pin, so that the overall structural strength of the sheep horn is improved. The conventional sheep horn needs to be pressed with a steel bushing 3 as shown in fig. 3-4 separately if the structural strength needs to be improved. The structural strength of the sheep horn is greatly superior to that of the traditional sheep horn, the failure risk caused by the cracking of the sheep horn is effectively prevented, and the safety risk is reduced.

Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present utility model and not for limiting the same, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the present utility model, which is intended to be covered by the claims of the present utility model.
