Abstract

The utility model relates to a back suspension soft pad assembly of an engine for an automobile, which is characterized in that: an extended upper bolt is arranged at the upper end of a pad body, and an extended lower bolt is arranged at the lower end of the pad body; the pad body comprises a lower pad plate and an upper pad plate, and the upper bolt is fixed on the upper pad plate; the lower bolt is fixed on the lower pad plate, and rubber is connected between the upper and lower pad plates; a cavity is reserved in the middle of the rubber, and the upper pad plate is provided with an inwardly extended frame; and upper pad frame rubber is filled in the inwardly extended frame, and a cavity is reserved in the middle of the upper pad frame rubber. The back suspension soft pad assembly has the advantages that: the Z-directional stiffness of a product is reduced and the X-directional and Y-directional stiffness is reduced to achieve stiffness matching, thus the effects of good shock isolation, small vibration and comfortable driving are achieved.

Description

Suspending soft cushion assembly behind the engine for automobile

Technical field

The utility model relates to a kind of automobile industry that is applicable to, particularly relates to a kind of automobile back damping pad.

Background technique

The back damping pad of motor car engine and vehicle frame joint use at present is to adopt the rubber of real core to be used as beam, its rigidity height, and isolating affection is poor, vibration is big, and driving comfortability is poor.

The model utility content

The purpose of this utility model just provides the good automobile back damping pad of a kind of isolating affection.

Solution of the present utility model is such: there is the last bolt that stretches out the upper end of its pad, and there is the following bolt that stretches out the lower end of pad, and described pad has lower bolster and punch pad, and last bolt is to be fixed on the punch pad, and following bolt is to be fixed on the lower bolster; Between last lower bolster, be connected with rubber; Leave cavity at described rubber middle part, the framework of stretching in described punch pad has is filled with pad frame rubber interior stretching in the framework, and cavity is left at the described pad frame rubber middle part of going up.

Be to increase isolating affection, the framework bottom of stretching in the described punch pad has the hole, is connected with to protrude upward on lower bolster, passes the hole of opening on the punch pad framework, and the projection that joins with last pad frame rubber.

The utility model has the advantages that the Z that reduces product to rigidity with improve X, Y to rigidity, realizes Rigidity Matching, it is good to reach shock insulation, vibrates the comfortable effect of little driving.

Embodiment

There is the last bolt 1 that stretches out the upper end of its pad of present embodiment, and there is the following bolt 5 that stretches out the lower end of pad, and described pad has lower bolster 4 and punch pad 2, and last bolt 1 is to be fixed on the punch pad 2, and following bolt 5 is to be fixed on the lower bolster 4; Between last lower bolster, be connected with rubber 3; Leave cavity 7 at described rubber 3 middle parts, the framework of stretching in described punch pad 2 has is filled with pad frame rubber 9 interior stretching in the framework, and cavity 8 is left at described pad frame rubber 9 middle parts of going up; The framework bottom of stretching in the described punch pad 2 has the hole, is connected with to protrude upward on lower bolster 4, passes the hole of opening on punch pad 2 frameworks, and the projection 6 that joins with last pad frame rubber 9.

The framework of stretching in the described punch pad 2 is a ladder-shaped frame, and described lower bolster 4 has the V-shaped part of inwardly stretching, and the opening of the V-shaped part that lower bolster 4 is inwardly stretched is greater than the ladder-shaped frame of stretching in the punch pad 2.

Last bolt 1 is to be connected with motor, and following bolt 5 is to be connected with vehicle frame 10, as shown in Figure 4.
