Problems solved by technology

In the current state of the art, elastic lugs consist of a molded body made of elastic material and a belt loop which is made of a tear-resistant fabric band and is placed on the molded body. The ends of the fabric band are sewn to form a closed band. The loop, where the overlapping ends of the fabric strips are sewn together, is stiffer than the rest of the loop. In addition, sewing the ends of the fabric strips together to form a loop with a smaller circumference is complex and expensive to produce. high

Embodiment 1

[0026] refer to Figure 1-Figure 5 , this embodiment proposes an elastic lug, including a molded body 2 and a belt ring 9, wherein:

[0027] The shaped body 2 is made of elastic material 13, the shaped body 2 comprises a base body with a rhomboid structure, in two opposite sides of the rhombic base body, a bearing structure 3 is formed by accommodating support pins or other elastic connecting elements, the support pins or other The elastic connecting elements are elastically supported by each other through elastic lugs 1 . There is a space between the two bearing structures 3, and the middle part of the bearing structure 3 is provided with a buffer block 5 extending toward the direction of the other bearing structure 3, and the two sides of the bearing structure 3 respectively extend along the direction of the other two sides of the rhombus base to form elastic arms 4 and the two elastic arms 4 of the bearing structure 3 are integrally connected with the two elastic arms 4 of...

Embodiment 2

[0035] refer to Figure 6 , Figure 7 The difference between the elastic lug 1 proposed in this embodiment and the first embodiment is that in this embodiment, the connection part 12 is arranged at the outer circumference 15 of the belt ring 9 and embedded in the area of ​​the elastic arm 4 . The two connecting parts 12 respectively abut against the corresponding outer circumference 15 of the belt loop 9 around the center of the lug 9 in the same direction of rotation; On the outer circumference 15 , the two connections 12 can thus abut in a completely symmetrical manner against the belt ring 9 in the bending region of the elastic arm 4 and they can both point obliquely away from the bearing structure 3 downwards.

[0036] The connecting portion 12 is held during the manufacture of the molded body 2 by the injection molding tool in the region where it joins the flange 8 .

Embodiment 3

[0038] refer to Figure 8 The difference between the elastic lug 1 proposed in this embodiment and the first embodiment is that in this embodiment, two connecting parts 12 are arranged on the inner circumference of the belt ring 9, and the connecting parts 9 extend toward the buffer block 5 and are embedded in the buffer block 5. In the molding process, the fabric strip 10 is arranged on the mold cores 16, 17 of the injection molding mold, the mold cores 16, 17 have ribs 18, 19 respectively matched with the grooves 6, 7 of the molded body 2; the connecting part 12 The region of the buffer block 5 protrudes from the inner circumference 14 into the molded body 2 and is embedded in the buffer block 5 .

Abstract

The invention provides an elastic lifting lug which comprises a forming body made of an elastic material and a belt ring made of a fabric belt and embedded in the forming body, and the tail ends of the fabric belt forming the belt ring are connected in a combined connecting mode to form a connecting part located on the outer circumference or the inner circumference of the belt ring. The lateral rigidity of the elastic lifting lug is increased to the maximum extent, the performance requirement is high, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust system accessories, in particular to an elastic lifting lug. Background technique [0002] As the main construction part of the car, the exhaust pipe system is the source of exhaust gas, vibration, and noise. It plays a very important role in purifying exhaust emissions, absorbing engine exhaust excitation noise, and noise from the chassis system. As the load-bearing and vibration-isolation parts of the exhaust system, the rubber part of the lifting lug plays the role of suspending the exhaust system and isolating the excitation from the exhaust system from the vehicle body. [0003] The elastic lifting lug is located at the bottom of the car, one end is connected to the body and the other end is connected to the exhaust system. The working environment is harsh. The elastic lifting lug not only needs to bear the weight of supporting the exhaust system, but also needs to withstand impact...
