Background technology
By the vibration receiver known in the art for being largely used to different purposes.One purpose is made using vibration receiver
For the detonation sensor of the function for monitoring the internal combustion engine in motor vehicle, but the present invention is not limited to the purpose.
The A1 of DE 44 03 660 and the C1 of DE 195 24152 respectively describe a kind of detonation sensor, the detonation sensor
With pressure house, sensor element and the vibrations quality and spring assembly of at least surrounding pressure house, the pressure range selector
Power sleeve by means of abutment face and can cause the component of vibration to act on to connect, and the spring assembly is with along the axial direction side of pressure house
Sensor element and vibrations quality are kept to the pretightning force of effect.In order to which detonation sensor is arranged on the component, make screw thread
Part grafting screws through pressure house and with the component.
Although having multiple advantages by vibration receiver known in the art, these vibration receivers are still containing improvement
Potentiality.Thus in this detonation sensor, there is the measuring unit of pressure house and ceramics to lead to prevent environment from influenceing
Cross thermoplastic hermetically injection encapsulated as far as possible.The particular geometric in labyrinth form on the pressure house being made of metal
Shape can be realized for the enough of moisture but limited sealing.Required seal geometry causes pressure house to be held high
Expensive processing, the pressure house have high manufacturing cost.In addition, only exist for the sealing of moisture in constrained environment,
Because forming gap because the thermal expansion of plastics and metal is different, moisture can be invaded by the gap.
The content of the invention
It is therefore proposed that a kind of vibration receiver, the vibration receiver is at least largely avoided known vibration and received
The shortcomings that device, and the vibration receiver even if also having improved sealing characteristics at different temperatures.
Pinking is especially configured to according to the vibration receiver for being used to receive the vibration for the component for causing vibration of the present invention to pass
Sensor.Vibration receiver includes the housing with interior room, the pressure house and sensor element being arranged in the interior room of housing, should
Sensor element surrounds pressure house.Pressure house is connected cohesively together by means of elastomeric material and case material.

Sub- power or molecular force keep together.Such connection is non-detachable connection simultaneously, and the connection is merely able to by the company of destruction
Agent is connect to separate.Within the scope of the invention, bonding and vulcanization are the sealed connections of possible material.
The use of elastomeric material provides advantages below：The elastomeric material not only reliably and is held with pressure house but also with housing
Connect long, and the sealing for intrusion medium is ensured by its elastic characteristic.It is it is possible thereby to obvious simpler and smaller
Ground manufactures pressure house, because no longer needing manufacture for sealing function and so far necessary labyrinth.Connect in addition, improving vibration
Receive the moisture-proof of device.
Elastomeric material can be bonding agent.Elastomeric material can be manufactured by silicones.Suitable material is, for example, silicones
Gel, the silicone gel can be crosslinked within the relatively short time by means of heat and/or ultraviolet light and be solidified into silicon
The block (Masse) of resin-like.
Pressure house substantially can construct to column around column axis.Pressure house can have the on mast axis
One axial end portion and the second axial end portion.Elastomeric material with being adjacent to the first axial end portion and/or the second axial end portion cloth
Put between pressure house and housing.
Cylinder is interpreted as by two parallel, flat, completely the same faces and a side face within the scope of the invention
The body of cylinder gauge in other words, wherein, side face is formed by parallel straight line.In other words, cylinder is by making flat face or curve
The rectilinear movement in the plane it is not located at along one to produce.This cylinder can preferably have circle within the scope of the invention
As basal plane.But it is also contemplated that other basal planes, such as oval or polygon basal plane.
Housing has recess with being adjacent to the first axial end portion and/or the second axial end portion.Elastomeric material can be with cloth
Put in the recess.Such recess can be realized in the injection moulding process of housing.Recess ensures, introduces enough elastomeric materials
For being attached with pressure house.
Recess can be structured as breach.Such breach is conically constructed and received as the extension into housing increases
Contracting.It is possible thereby to realize that big surface is used to be attached with elastomeric material.
Pressure house can have a flat outside, and the outside is towards housing.Flat outside is within the scope of the invention
Such face is interpreted as, the face constructs in the case of the component that no protuberance or other mutation formulas stretch out.Elastomeric material
Offer advantages below is provided：The elastomeric material is not only connected reliably and enduringly with pressure house but also with housing, and is led to
Cross its elastic characteristic and establish the sealing for being directed to intrusion medium.It is possible thereby to it is obvious simpler and smaller manufacture pressure house,
Because manufacture is no longer needed for sealing function necessary labyrinth so far.In addition, improve the moisture-proof of vibration receiver.
Housing can be by plastic manufacturing.Housing can be manufactured using more favourable plastics by using elastomeric material, institute
Stating plastics can more simply process.The relatively high-freedom degree in terms of manufacturing parameter is appeared in injection moulding process.Elastomeric material
Injection can be carried out after injection moulding process, wherein it is possible to be crosslinked using the existing heat of the component.
Pressure house can be manufactured by metal.The use of elastomeric material provides advantages below：The elastomeric material not only with pressure
Power sleeve and reliably and durably it is connected with housing, and the sealing for intrusion medium is established by its elastic characteristic.
Pressure house can have the drop-center for being used for receiving immobilising device, and the immobilising device is used for vibration receiver
Fix on the members.Thus, it is possible to fix vibration receiver in a straightforward manner.
The basic conception of the present invention is by the elastic sealed connection of material, for example produced by means of silicone adhesive
Sealing function so that elastomeric material is not only connected from pressure house but also with housing (both are generally by different material manufactures),
And the sealing for intrusion medium is established by its elastic characteristic.Because it is attached on auxiliary connection to elastomeric material face formula, institute
Not need geometry in particular to be sealed.
