Abstract

The present invention relates to a component (10) and a covering hood composed of the said component to cover the components of the internal-combustion, such as a component of the control transmission gear. A surface of a component (10) facing a sound-emitting part of the engine, is at least partially coated with a sound-absorbent material layer.

Description

The member and the housing that are used for the component of internal-combustion engine
Technical field
The present invention relates to belong to the member of the component that are used for the cover cap internal-combustion engine of preamble section before the claim 1 and also relate to a housing that is used for these component that belongs to preamble section before the claim 4.
Background technique
So far general fashion is the elastomeric seal structure to be set or foam removes the plastic seal structure in for the housing of the motor of eliminating noise, and they for example are positioned in the below of engine hood.Yet this structure is increasing sharply with cost of both expensive when assembling especially.
Summary of the invention
Task of the present invention for this reason is, provides to belong to a member and a cover cap that starts alleged type, and they all are being improved aspect cost of production and the effect.
This task according to invention require by one belong to the characteristic that starts alleged type with claim 1 feature member and solve by a housing that belongs to the feature of the characteristic that starts alleged type with claim 4.The present invention's favourable organization plan is described in the dependent claims.
Require in the member of an alleged type, to stipulate that a surface in the face of the member that sends noise of internal-combustion engine of this member is provided with a silencing plate of fixedlying connected with this surface at least in part according to invention.In the housing of an alleged type, require to be provided with such member according to invention.
Such advantage is, by making minimizing of airborne noise discharging, and isolation by solid borne noise and the acoustic efficiency that reduces just to obtain an improvement by a noise reflection.
The improvement of good especially acoustic efficiency so realizes in surprising mode under the manufacturing situation easy at the same time and with low cost: the layer structure of this noise elimination is a cashmere-planted layer (Beflockung).In addition, by an improved sealing configuration pollution being entered reduces.
This member for example is a plastic member or a plate members.Description of drawings
The present invention's additional features, advantage and favourable organization plan be providing and followingly by accompanying drawing the present invention being illustrated by subordinate then.Be illustrated as:
Fig. 1 be one by the invention requirements member one exemplary embodiment with;
Fig. 2 is for the diagrammatic curve explanation of test result of noise measurement that does not have and be provided with the housing of member of the present invention;
Embodiment
The exemplary member of describing by setting of the present invention relates to the cingulum housing 10 of a bottom in Fig. 1.One of this housing 10 in the face of the dorsal surface of not shown cingulum except zone 12 and 14 and bolt head bearing surface 15 fully planted suede.This flocking is that the surface by the coating of a kind of binder and member 10 is fixedly linked, so the acoustic characteristic of this component wall is the same with its vibration characteristics is influenced by this flocking.
Adopt a housing that is used for cingulum to do a test, wherein obtained the dependence of an acoustic pressure and a revolution.At first, this test is carried out with a housing with conventional components, then carries out with a housing with flocking member of the present invention.Fig. 2 then with diagrammatic curve the result of this test has been described, wherein on axis 16, described an acoustic pressure dB (decibel) (A) on axis 18, described a revolution 1/min (minute).The acoustic pressure of having measured when curve 20 has shown the housing that adopts traditional cingulum and the variation relation of revolution; And curve 22 has shown and has adopted the inboard acoustic pressure of measuring during by the housing of the cingulum of flocking and the variation relation of revolution.As can directly finding out, surprisingly by the acoustic pressure in the revolution zone of all measuring will be significantly in having been planted the housing of suede less than the sort of not by the situation in the housing of flocking.This flocking simultaneously is simple and with low cost and can produces manufacturing in batches with enough process safety.
This cashmere-planted layer is a kind of manufacturing process Economy technology afterwards with member that is attempted by housing of high satisfaction, and wherein, the manufacturing process of this member needn't be changed.A high elasticity of this cashmere-planted layer just can realize when housing being assembled into accordingly between member or on the impingement position between member and other engine components that a kind of point and face that has the seal action of acoustic efficiency highly and machinery accordingly compresses.This restricting can freely be selected in process of production.In addition, the layer structure with flocking also can be used in these bear slide and members of moving movement in.
