Abstract
The invention provides an automobile engine suspension cushion assembly which comprises a driving side cushion, driven side cushions and a metal supporting frame. The driving side cushion is arranged on the metal frame and is in interference fit with the metal frame, automobile body longitudinal beams or connecting holes of a chassis are connected with the two ends of the metal frame, the driven side cushions are assembled on the connecting holes and are in interference fit with the connecting holes, and driven side cushion inner sleeve tubes of the driven side cushions and the connecting holes are concentric. The mode that the driving side rubber cushion and the driven side rubber cushions are integrated through the metal support is adopted, the driving side cushion is mainly stressed, the driven side cushions achieve the functions of auxiliary adjusting and vibration isolation and system decoupling, and the ideal vibration isolation effect can be achieved.
Description
Technical field
The invention belongs to automobile power assembly suspension system technical field, be specifically related to a kind of automobile power assembly suspending cushion assembly structure.
Background technology
The development tendency of automobile is just towards lightweight, miniaturization, low cost, low noise, comfortableization develop rapidly, and as the driving engine of automobile heart as main soruce of vibration, the main pipeline of its vibration is exactly will vibrate with noise transmission to vehicle body by suspension system, and then is delivered to driving compartment.And the power assembly suspension system elastic connecting system between dynamic assembly and vehicle body just, it mainly plays support, spacing, vibration isolation effect.Therefore the quality of design on Mounting System directly affects the travelling comfort of automobile.By can improve to a great extent the NVH characteristic of automobile to the optimal design of suspension system.
In the middle of increasing practice, we find only to select traditional mounting structure, referring to Fig. 1, traditional similar structures is mainly take 1 vibration isolation of master end cushion as main, without the rubber mount of passive side, under some particular case (as comfort property is required to higher situation), can not meet high-tech engine vibration characteristic demand with rapid changepl. never-ending changes and improvements completely, must carry out optimal design mounting structure according to different engine power characteristics, and then improve the NVH characteristic of automobile.
Summary of the invention
Of the present inventionly provide a kind of engine for automobile suspending soft cushion assembly structure, object is better to mate engine vibration characteristic, particularly to car load traveling comfort, requires higher situation that a scheme is provided, and then improves the NVH performance of car load.
The technical scheme that the present invention takes is as follows;
Suspending soft cushion assembly structure of the present invention comprises master end cushion, passive side cushion and metallic support skeleton.The mode that adopts active and passive side rubber mount to become one by metallic support.Master end rubber mount and passive side rubber mount all adopt bush type structure, and the vibration characteristic according to driving engine under each order is mated rigidity and the linear dimensions of active and passive side rubber spring.Thereby reach desirable vibration isolating effect.
Described suspending soft cushion assembly adopts active and passive side rubber mount to be installed on metallic support, becomes one.Master end cushion is arranged on metallic framework, with metallic framework interference fit, there is the connecting bore that connects chassis runner or chassis at the two ends of metallic framework, are equipped with passive side cushion in connection hole, with connecting bore interference fit, the passive side cushion inner sleeve of passive side cushion is concentric with connecting bore.
Like this, master end cushion is installed between two passive side rubber mounts, and master end cushion plays main vibration isolation effect, i.e. the position of rubber entity maximum, and the inner sleeve at its center is used for connecting master end support, and then is connected on dynamic assembly.The inner sleeve that two passive side rubber mounts are bolted Jiang Qi center coordinates fastening with automobile longitudinal girder or chassis, as Fig. 4 (only enumerates a kind of mounting means herein, in fact can adjust according to the rigidity requirement of different directions the direction of the rubber mount that passive side is little, change connection mode).
Adopt structure of the present invention, wherein main stressed be master end cushion, passive side cushion plays the effect of auxiliary adjustment vibration isolation, system decoupling.Passive side cushion generally adopts symmetric design, and with regard to rubber parameter, general passive side cushion will select rigidity to be far longer than the cushion in master end, can alleviate master end and vibrate the larger displacement bringing more greatly.
The present invention has the following advantages:
1, the mode that adopts active and passive side rubber mount to become one by metallic support, realizes the effect of two-stage vibration isolation.
2, main stressed be master end cushion, passive side cushion plays auxiliary adjustment decoupling zero and avoids the effect of resonance frequency.
3, integrated morphology convenient for assembly, avoid repeatedly assembly accumulation error.
4, novel structure, comparatively flexible to requirements of installation space.

In figure: 1, master end cushion, 2, master end cushion inner sleeve, 3, passive side cushion, 4, metallic framework, 5, passive side cushion inner sleeve, 6, passive side rubber spring, 7, passive side cushion outer tube, 8, suspending soft cushion assembly, 9, chassis runner.
The specific embodiment
Below in conjunction with drawings and embodiments, the present invention is described in further detail:
Referring to Fig. 2, Fig. 3 and Fig. 4, the master end cushion 1 of this engine for automobile suspending soft cushion assembly is conventional bush type structure cushion, rubber spring, inner sleeve 2 and outer tube, consists of.Passive side cushion 3 is the bush type structure cushion that small volume and rigidity are larger, passive side rubber spring 6 and inside and outside sleeve pipe 5 and 7, consists of.Active and passive side cushion is and metallic framework interference fit.Master end cushion 1 is arranged on the middle part of metallic framework 4, there is the connecting bore that connects chassis runner or chassis at the two ends of metallic framework, two passive side cushions 3 are assemblied in described connection hole, and with connecting bore interference fit, the passive side cushion inner sleeve 5 of passive side cushion is concentric with connecting bore.
The inner sleeve 3 at cushion center, master end is for connecting master end support, and then is connected on dynamic assembly.Two rubber mounts that passive side is little, the passive side cushion inner sleeve 5 that is bolted Jiang Qi center coordinates fastening with automobile longitudinal girder 9.
In the present invention, if aluminum alloy or plastic-metal skeleton can consider to omit active and passive side cushion outer tube, adopt directly the vulcanization of rubber to the mode on metallic framework.
