Description

Technical Field

[0001] The utility model belongs to the technical field of automobile engines, and in particular relates to a combined automobile engine shock-absorbing pad. Background Art

[0002] The vibration generated when the car engine is working will cause the chassis to vibrate, affecting the car's handling and comfort. Therefore, a vibration damping pad should be installed between the car engine and the chassis to minimize the transmission of the engine vibration to the chassis. The working principle is to use the elastic deformation of the vibration damping pad to absorb the vibration generated by the engine. However, the existing engine shock-absorbing pad is a solid rubber block with an integrated structure. During use, the ability of the shock-absorbing pad to slow down and absorb vibration is limited. It is easy for most of the vibration to fail to slow down and absorb, affecting the shock-absorbing effect of the engine. On the other hand, under the influence of environmental conditions such as temperature and humidity changes and the degree of vibration, the shock-absorbing pad will be deformed after long-term use, resulting in a lack of pressure distribution and support structure on the outside of the shock-absorbing pad, affecting the life of the shock-absorbing pad during use.

[0003] In view of the above problems, it is necessary to carry out innovative design based on the original shock-absorbing pad structure and develop a new type of shock-absorbing pad. Utility Model Content

The pad 4 includes a rubber layer 6, a rib layer 7, and a pressure-bearing layer 8. The rib layer 7 is horizontally arranged in the rubber layer 6, and the pressure-bearing layers 8 parallel to the rib layer 7 are respectively arranged on the upper and lower surfaces of the rib layer 7. The three are arranged in a sandwich structure, and the rubber layer 6, the rib layer 7 and the pressure-bearing layer 8 are arranged as an integrally formed structure, which improves the overall compressive and deformation resistance, reduces the frequency of fatigue damage of the upper pressure pad 2 and the lower pressure pad 4, extends the service life, and improves practicality. The strengthening layer 9 is coated on the outer surfaces of the upper pressure pad 2 and the lower pressure pad 4, and a through hole is provided on the strengthening layer 9 corresponding to the mounting hole 10.

[0014] The tendon layer 7 is a metal sheet with holes of 0.3-1 cm in diameter, or the tendon layer 7 is a metal mesh with a mesh diameter of 0.3-0.5 cm, so that the rubber layers 6 on the upper and lower surfaces of the tendon layer 7 can be connected as a whole, while ensuring the strength of the tendon layer 7 and enhancing the adhesion between the rubber layer 6 and the tendon layer 7.

[0015] The pressure-bearing layer 8 is a cord made of rayon, nylon or aramid material, which improves the pressure-bearing capacity and impact load resistance of the rubber layer 6 and prolongs its service life.

[0016] The mounting hole 10 is provided with a metal sleeve 12 for protection, thereby improving the compressive and anti-deformation strength of the mounting hole 10, and preventing the shock-absorbing pad from being deformed / cracked due to the tightening force of the bolt 17 and the subsequent pressure during installation and later use, and losing the connection with the bolt 17 and falling off; further, the metal sleeve 12 is provided with an internal thread for easy installation and fixation.

[0017] Furthermore, the length of the metal sleeve 12 is smaller than the length of the mounting hole 10 to match the elasticity of the upper pressure pad 2 and the lower pressure pad 4 to avoid interference.

[0018] The reinforcing layer 9 is made of a steel sheet with a thickness of not less than 0.2 cm. The reinforcing layer 9 is used to divide the applied pressure to avoid direct squeezing, deformation and damage to the top, bottom and side walls of the shock-absorbing pad.

[0019] A connecting plate 13 is arranged on the top of the upper pressure pad 2, and the connecting plate 13 is arranged in a "︺" shape. Ear plates 14 parallel to its bottom plate are arranged on both sides of the connecting plate 13. The two are arranged in an integrated structure.

[0021] At least one rib layer 7 is disposed in each of the upper pressure-bearing pad 2 and the lower pressure-bearing pad 4 , and at least one pressure-bearing layer 8 is disposed on the upper and lower surfaces of the rib layer 7 .

[0022] The working mode of the utility model is as follows: when in use, the lower pressure pad 4 and the upper pressure pad 2 are connected and combined into one body as a pressure pad block 1 through the screw rod 11. At this time, the protruding portion 3 of the upper pressure pad 2 is engaged with the recessed portion 5 of the lower pressure pad 4 to prevent shaking and misalignment between the lower pressure pad 4 and the upper pressure pad 2; secondly, the lower end of the screw rod 11 is connected and fixed to the connecting part of the frame or the mounting frame by a nut, so that the shock-absorbing pad is located between the engine and the frame or the mounting frame, and the upper end of the screw rod 11 is connected and fixed to the connecting hole 15 of the engine by a nut.

[0023] The vibration generated by the engine is first transmitted to the upper pressure pad 2 for elimination, and then passed to the lower pressure pad 4 for elimination. The vibration received is eliminated by two-level elimination and force unloading, which effectively reduces the vibration transmitted to the frame or mounting frame; the vibration generated by the frame or mounting frame is first transmitted to the lower pressure pad 4 for elimination, and then passed to the upper pressure pad 2 for elimination. The vibration received is eliminated by two-level elimination and force unloading, which effectively reduces the vibration transmitted to the engine by the frame or mounting frame.

[0024] During use, when the upper pressure pad 2 or the lower pressure pad 4 is damaged, only the damaged upper pressure pad 2 or the lower pressure pad 4 needs to be replaced without replacing the entire pad; when installation is inconvenient and it is necessary to adjust the installation height or install an auxiliary frame, choose to install the connecting plate 13 to the top of the upper pressure pad 2 or the bottom of the lower pressure pad 4, and connect it to the screw rod 11, and the bottom of the bolt 17 on the ear plate 14 of the connecting plate 13 is pressed and fixed to the top of the upper pressure pad 2.

[0025] During use, the special structure of the steel connecting plate 13 also has a certain elasticity. Under normal circumstances, it provides support. When it is subjected to extreme vibration force, such as vibration caused by external force colliding with the frame, the elasticity of the connecting plate 13 can be combined with the upper pressure pad 2 and / or the lower pressure pad 4 for buffering and shock absorption. The upper pressure pad 2 provides support for the bottom end of the screw 11 for buffering, or the lower pressure pad 4 supports the bottom end of the screw 11 to increase the contact area of ​​the lower pressure pad 4, share the extreme vibration force buffering and shock absorption, and further improve the mitigation and absorption of vibration while improving the connection support strength of the connecting plate 13.
