Description

Technical Field

[0002] The existing press-fitting rivet for a differential includes an inner ring and an outer ring. The outer ring needs to be sleeved on the inner ring. In order to prevent the outer ring from separating from the inner ring, after the outer ring is sleeved on the inner ring, additional rivets are often used by a press riveting device to relatively fix the inner ring and the outer ring. Therefore, the steps of fixing the inner ring and the outer ring in the related art are relatively cumbersome, which leads to a low production and assembly efficiency of the differential. In addition, by connecting with additional rivets, there is also a phenomenon that the inner ring and the outer ring are separated due to the instability of the rivets.

[0003] Therefore, it is necessary to provide a press-fitting rivet for a time-sharing four-wheel drive differential. Summary of the Utility Model

[0021] The present utility model will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0022] Please refer to Figure 2 , Figure 2 is a perspective view of the optimal embodiment of the press-fitting rivet of a time-sharing four-wheel drive differential of the present utility model. As Figure 2 shown, at least one embodiment provides a press-fitting rivet for a time-sharing four-wheel drive differential, including: an inner ring 1, the inner ring 1 having a top surface and a bottom surface, a lifting part 3 is provided along the outer ring 4 edge of the bottom surface, and a press riveting part 2 is provided along the outer ring 4 edge of the top surface. The press-fitting rivet further includes an outer ring 4, and the outer ring 4 is sleeved on the inner ring 1. The outer ring 4 and the inner ring 1 are in a separated state. The outer ring 4 needs to be grabbed by a press-fitting device and then sleeved on the inner ring 1. When it is sleeved to the bottom, the press riveting part 2 on the edge of the inner ring 1 is punched, so that it deforms and extends to the top surface of the outer ring 4, and then the inner ring 4 is relatively fixed between the lifting part 3 and the press riveting part 2 on the inner ring 1, saving the production reinforcement steps of the differential component production, providing production efficiency, and enhancing the connection stability strength of the rivet.

[0023] Lifting part 3

[0024] Please continue to refer to Figure 1 . AsFigure 1 As shown, the lifting part 3 includes a plurality of supporting platforms. The supporting platforms and the inner core 1 are integrally formed. The supporting platforms are used to abut against the bottom surface of the outer ring 4. In addition, the outer contour of the supporting platforms can be a rectangle spliced to an arc, or it can be arc-shaped. Specifically, in order to achieve a better stable lifting effect, the distance between adjacent two supporting platforms is equal. The bottom surface of the outer ring 4 abuts against the top surface of the supporting platforms.

[0025] The riveting part 2

[0026] Please refer to Figure 1 and combine with Figure 3 , Figure 3 , which is a three-dimensional view of the pressed state of the inner ring of the present utility model. As Figure 1 and Figure 3 shown, the riveting part 2 protrudes from the top surface of the inner ring 1. The riveting part 2 includes 6 groups of riveting positions. The angle between adjacent two groups of riveting positions is the same. Each group of riveting positions includes a first riveting area and a second riveting area. The thickness of the first riveting area and the second riveting area is 0.4 mm. After being stamped, there is no protrusion on the top surface of the inner ring 1. The angle between the line connecting the center of the first riveting area and the inner ring 1 and the line connecting the center of the second riveting area and the inner ring 1 is 6° - 22°. Before the first riveting area and the second riveting area are stamped, it is composed of an arc protruding on one side and an arc concave on the other side. After being stamped, an extended stop piece 5 is formed. The extended stop piece 5 is circular. The first riveting area and the second riveting area are stamped to form the extended stop piece 5. The extended stop piece 5 protrudes from the outer surface of the inner ring 1. The thickness of the extended stop piece 5 extends towards the supporting platform. The top surface of the outer ring 4 abuts against the bottom surface of the extended stop piece 5.

[0027] In summary, by setting the riveting part 2, during the process of relatively fixing the inner ring 1 and the outer ring 4, the production reinforcement steps are saved, the production efficiency is improved, and the connection stability strength of the riveted parts is enhanced; the phenomenon of the separation of the inner ring 1 and the outer ring 4 is avoided.
