[0017] Example: refer to Figure 1-Figure 5 , rubber buffer device, including rubber pad 1, iron core 2 and gasket 3, rubber pad 1 adopts an integral vulcanized structure, adopts the compression deformability of rubber, and is pressed into the bracket hole by compressing rubber pad 1, due to the elasticity of rubber And it will be deformed after being stressed. At the same time, in order to tighten the bolts, an iron core 2 and an iron gasket 3 are added to support the bolts. The iron core 2 and the gasket 3 are assembled after the rubber pad 1 is assembled. 2. Finally, the iron gasket 3 is riveted on the iron core 2. When loading the vehicle, the bolt passes through the gasket 3 and the iron core 2 and finally connects to the vehicle. The bolt, gasket 3, iron core 2, and body 5 are all The iron parts are connected with the iron parts, and the rubber pad 1 completely isolates the direct iron parts of the bracket 4 and the vehicle body 5 from being connected with the iron parts...

The invention discloses a rubber buffer device and relates to the field of automobiles. The rubber buffer device comprises a rubber pad, an iron core and a gasket, wherein the rubber pad is pressed into a bracket hole by compressing the rubber pad due to compression deformability of rubber, the iron core and the gasket are assembled after the rubber pad is assembled, and finally the iron gasket is riveted on the iron core. The bolt, the gasket, the iron core and the vehicle body are all connected through iron pieces, the direct iron piece and iron piece connection between the bracket and the vehicle body is completely isolated through the rubber gasket, and therefore vibration excitation generated by an engine is isolated. In order to quickly release the energy transmitted by the engine after the rubber pad absorbs the energy, the diameter phi D1 of the outer circle of the iron core is smaller than the diameter phi D2 of the outer circle of the rubber pad, energy of the rubber pad can be quickly released through the fact that the rubber pad is not in contact with the iron core, and the effect of absorbing vibration and noise is achieved.
Description
technical field [0001] The invention relates to the field of automobiles, in particular to a rubber buffer device. Background technique [0002] At present, the transmission shaft assembly is two-stage. The bracket and bracket on the transmission shaft are connected by bolts, and the bracket is connected to the body by bolts. The bracket and bracket, bracket and body are all iron parts and iron parts. The direct contact between them is a rigid connection. [0003] At present, when the whole vehicle is at 3700rpm-4000rpm, there is a lot of vibration and roar, mainly because the secondary vibration excitation of the engine is transmitted to the drive shaft, and the drive shaft amplifies the vibration and roar. At present, the bracket and the bracket on the transmission shaft, and the bracket and the vehicle body are all rigidly connected, which cannot isolate the vibration excitation generated by the engine. Contents of the invention [0004] The purpose of the present inv...
