Abstract
The invention aims to provide an auxiliary frame damping structure, which is simple in structure, is light in weight, is convenient to for process implementation and is low in cost. The auxiliary frame damping structure provided by the invention comprises an auxiliary frame and a weight-balancing and buffering device, wherein the weight-balancing and buffering device is arranged on the auxiliary frame, and can vibrate relative to the auxiliary frame; the weight of the weight-balancing and buffering device is one eighth that of the auxiliary frame; and the first-order modal frequency of the weight-balancing and buffering device is consistent with that of the auxiliary frame. The auxiliary frame damping structure provided by the invention has a remarkable damping effect, and has very high generality; and moreover, the damping requirements of different auxiliary frames can be met easily by replacing or adjusting the weight-balancing and buffering device.
Description
Technical field
The present invention relates to the suspension system of car, in particular, relate to a kind of subframe vibration-proof structure in the suspension system.
Background technology
The skeleton of vehicle bridge before and after subframe can be regarded as is the middle device that connects vehicle body and wheel, plays support, vibration isolation and improves suspension rate.Subframe not only connects vehicle body and wheel, but also by the engine-mounting bracket connecting engine.In actual driving process, subframe also will be subjected to the excitation from driving engine except being come road excitation, and wherein Engine Excitation is larger to subframe vibration effect.Subframe generally adopts the panel beating after the punching press to be welded, and therefore general being difficult to reaches the vibration damping purpose by change subframe sheet metal structural; When if same vehicle adopts different dynamic assemblies or other vehicle to continue to use this subframe, meeting is so that this subframe can not satisfy the vibration damping requirement, this just need to carry out structure optimization to this subframe, not only increases thus cost of product, but also can prolong product development cycle.
Summary of the invention
The objective of the invention is to propose a kind of simple in structure, lightweight, convenient and subframe vibration-proof structure with low cost of technique realization.
Subframe vibration-proof structure of the present invention comprises subframe and counterweight shock absorber, and described counterweight shock absorber is installed on the subframe, and can vibrate with respect to subframe; The weight of described counterweight shock absorber be subframe weight 1/8, and the single order model frequency of counterweight shock absorber is consistent with the single order mode of subframe.
The counterweight shock absorber can be installed on the subframe quiveringly, and the subframe of this moment becomes the double freedom part by the single degree of freedom part.When the subframe vibration-generating, the counterweight shock absorber can play the effect of damped vibration.Because counterweight shock absorber and subframe are the split designs, so the production of subframe and debug all more convenient.When this subframe is applied to change on dynamic assembly and other vehicle, can passes through to regulate position or the weight of counterweight shock absorber, thereby reach at an easy rate the requirement of cushioning performance.
Further, above-mentioned counterweight shock absorber has following two kinds of forms:
1, described counterweight shock absorber comprises counterweight disk and bolt, and described counterweight disk is provided with bolt hole, and a side of bolt hole is equipped with rubber pad by groove; Then the described rubber pad of described screw bolt passes and bolt hole, subframe screw with nut, thereby the counterweight shock absorber is installed on the subframe.
2, described counterweight shock absorber comprises the first counterweight disk, the second counterweight disk and bolt, and described the first counterweight disk and the second counterweight disk are equipped with bolt hole, and a side of bolt hole is equipped with rubber pad by groove; Then bolt hole and the rubber pad of the rubber pad of described screw bolt passes the first counterweight disk and bolt hole, subframe, the second counterweight disk screw with nut, thereby the counterweight shock absorber is installed on the subframe.
The structure of the counterweight shock absorber of above-mentioned two kinds of forms is all fairly simple, because the effect of rubber pad can realize with respect to the subframe vibration, thereby realize preferably effectiveness in vibration suppression.
Further, described rubber pad comprises inner tube and vulcanizes in the rubber block of inner tube periphery that the length of described inner tube is less than the length of rubber block, by the design of inner tube, can avoid radially directly contacting with bolt of rubber block, and then make rubber block unnecessary wearing and tearing occur.
Further, be vibration damping better, the damping value of described rubber block is greater than 1; Described counterweight shock absorber is installed on the single order mode resonance maximum distortion place of subframe.
Subframe vibration-proof structure effectiveness in vibration suppression of the present invention is obvious, and can by changing or regulating the vibration damping requirement that the counterweight shock absorber is easy to adapt to different subframes, have good commonality.

The specific embodiment
The below contrasts accompanying drawing, by the description to embodiment, the effect of the mutual alignment between the shape of the specific embodiment of the present invention such as related each member, structure, the each several part and annexation, each several part and principle of work etc. are described in further detail.
Embodiment 1:
As shown in the figure, the subframe vibration-proof structure of present embodiment comprises subframe 1 and counterweight shock absorber 2, and counterweight shock absorber 2 is installed on the subframe 1, and can be with respect to subframe 1 vibration; The weight of counterweight shock absorber 2 is 1/8 of subframe 1 weight, and the single order model frequency of counterweight shock absorber 2 is consistent with the single order mode of subframe 1.
Be vibration damping better, the damping value of rubber block 10 is greater than 1; Counterweight shock absorber 2 is installed on the single order mode resonance maximum distortion place (for example middle position) of subframe 1.
