Abstract

The utility model discloses a rubber buffer device, which relates to the field of automobiles and comprises a rubber pad, an iron core and a gasket, wherein the rubber pad is pressed into a bracket hole by adopting the 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 by iron pieces, and the rubber gasket completely isolates the direct connection of the iron pieces and the iron pieces of the bracket and the vehicle body, so that the vibration excitation generated by an engine is isolated. In order to solve the problem that the rubber pad absorbs the energy transmitted by the engine and then is quickly released, 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, and the rubber pad is not in contact with the iron core, so that the energy of the rubber pad can be quickly released, and the effect of absorbing vibration and noise is achieved.

Description

Rubber buffer device

Technical Field

The utility model relates to the field of automobiles, in particular to a rubber buffer device.

Background

At present, a transmission shaft assembly is of a two-section type, an upper support of a transmission shaft is connected with a bracket through a bolt, the bracket is connected with a vehicle body through a bolt, and the support, the bracket, the vehicle body and the vehicle body are in direct contact with an iron piece and are in rigid connection.

At 3700rpm-4000rpm of the whole vehicle at present, great vibration and booming sound exist, mainly secondary vibration excitation of an engine is transmitted to a transmission shaft, and the transmission shaft amplifies the vibration and the booming sound. At present, the upper bracket and the bracket of the transmission shaft and the bracket and the vehicle body are all rigidly connected, so that the vibration excitation generated by the engine cannot be isolated.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art and provides a rubber buffer device which has the effects of isolating the vibration excitation of an engine from being transmitted to a transmission shaft and eliminating the vibration and the roaring of the whole vehicle.

The purpose of the utility model is achieved by the following technical scheme: the rubber buffer device comprises a rubber pad, an iron core and a gasket, wherein the rubber pad is compressed and deformed, the rubber pad is pressed into a bracket hole through the compression deformability of rubber, the iron core is assembled on the iron core and the gasket after the rubber pad is assembled, and finally the iron gasket is riveted on the iron core.

Furthermore, the outer circle diameter phi D1 of the iron core is smaller than the outer circle diameter phi D2 of the rubber pad.

The utility model has the beneficial effects that:

the bolt, the gasket, the iron core and the vehicle body are all connected by iron pieces, and the rubber pad completely isolates the direct connection between the iron pieces and the iron pieces of the bracket and the vehicle body, so that the vibration excitation generated by the engine is isolated.

In order to solve the problem that the rubber pad absorbs the energy transmitted by the engine and then is quickly released, 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, and the rubber pad is not in contact with the iron core, so that the energy of the rubber pad can be quickly released, and the effect of absorbing vibration and noise is achieved.

Detailed Description

The utility model will be described in detail below with reference to the following drawings:

example (b): referring to fig. 1-5, rubber buffer, including rubber pad 1, iron core 2 and gasket 3, rubber pad 1 adopts the whole vulcanization structure, adopt the compression deformability of rubber, it is downthehole to press into the bracket through compression rubber pad 1, because rubber is flexible and can warp after the atress, also can tighten for the bolt simultaneously, iron core 2 and iron gasket 3 have been increased and have been come the support bolt, iron core 2 and gasket 3 are after assembling rubber pad 1, assemble iron core 2, at last rivet iron gasket 3 on iron core 2, the bolt passes gasket 3 and iron core 2 and connects at last on the car during the loading, the bolt, gasket 3, iron core 2, automobile body 5 are all that the ironware is connected with the ironware, rubber pad 1 has completely isolated bracket 4 and automobile body 5's direct ironware and is connected with the ironware. In order to solve the problem that the rubber gasket 1 is quickly released after absorbing the energy transmitted by the engine, the excircle diameter phi D1 of the iron core 2 is smaller than the excircle diameter phi D2 of the rubber gasket 1, and the energy of the rubber gasket 1 can be quickly released by the fact that the rubber gasket 1 is not in contact with the iron core 2, so that the vibration and noise absorption effect is achieved.

It should be understood that equivalent alterations and modifications of the technical solution and the inventive concept of the present invention by those skilled in the art should fall within the scope of the appended claims.
