Description
Background technology
The present invention relates to a kind of by claim 1 Wiper bearing as described in the preamble.
Fixedly holding when the Wiper bearing housing is used for supporting wiper shaft, location Windshield Wiper axis and is installed in automobile.Particularly under snow-load or kayser situation, can produce big power and moment of torsion in the main transitional region between Wiper bearing housing and thin plate pipe.
Disclose a kind of wiper device in DE 199 25 292 A1, wherein the thin plate pipe has the cross-sectional plane of an increase in transitional region, and it has reduced the specific load in important transitional region, and has improved bending and torsional strength.
Summary of the invention
In Wiper bearing of the present invention, a ring-type element with the axle journal coaxial arrangement is set in the axle journal outside that is used for fixing the thin plate pipe that is provided with.This axle journal is captiveed joint with the outer tube of the formation bear box of Wiper bearing, perhaps captives joint with the interior pipe that outer concentric tube is arranged with one.Be connected with the form fit of axle journal by the thin plate pipe, power and torsional stress are delivered to axle journal by bear box.Axle journal mainly bears pulling force, pressure and torsional stress now.This ring-type element is connected pole and bears moment of flexure and flexure stress with it.The suffered mechanical load of axle journal is less and be uniform on the whole.Ring-type element mainly bears flexure stress, and it acts in the plane, and this plane is made of bearing axis and axle journal.The thin plate pipe is by the ring-type element supporting and correspondingly alleviate load for axle journal.Itself very little flexural load only occurs on axle journal.The ring-type element of two coaxial arrangement also can be set.Have very high stability and simplified being connected of thin plate pipe and axle journal at ring-type element in addition.When axle journal connected on inner pipe, version was compact especially.In not only being delivered to, this power on the pipe, also is delivered on the outer tube.
Because load is very little, under the interior pipe or the situation apart from shortening between the bearing region on the outer tube at bear box, axle journal and its transition geometric configuration between the bearing position on the bear box can design simply at join domain between axle journal and the thin plate pipe and axle journal.The Wiper bearing that Wiper bearing, particularly plastics are made is can design-calculated shorter and compacter than plastics Wiper bearing up to now, wherein must be noted that long, transitional region uniformly, so that the mechanical strees peak value that reduces to occur there.By Wiper bearing compact design form, the thin plate pipe can shift near the bearing region of Windshield Wiper axis, thus can be so that total system rigidity is bigger.Because bear box bears homogeneous mechanical load, this bear box can be designed to even thin-walled, and this is particularly advantageous for the scheme of making Wiper bearing with plastics, can avoid shrinkage cavity occurring in the plastics during fabrication.Can realize shorter hardening time and production cycle during fabrication in addition.Reduce relevantly with deadweight, the manufacturing and the assembly cost of Wiper bearing that has ring-type element is also cheaper.The cross-sectional plane of thin plate pipe is can design-calculated less, this means reducing and littler structure space demand of weight.For example under the situation of kayser, the wiper stand that has a thin plate pipe with smaller cross-sectional area makes all members of wiper system-comprise scrape water arm-lighten the load by elastic deformation, can further save cost thus, because these members can design simplyr.
When wiper device is worked because less motion appears in the layout of ring-type element and the improvement of thin plate piping support in bearing region, even and under high load capacity the junction can not lose efficacy yet.In fact the orientation of wiper shaft remains unchanged, and remains unchanged according to designing the orientation angle of definite swept area of wiper blade with respect to vehicle glass like this, has guaranteed the good water quality of scraping thus.
Although preferably use unstrengthened plastics to be used for Wiper bearing, can realize the high rigidity of structure and improve the rigidity of total system by special geometric form.Can expand the field of application of wind screen wiper drive thus with plastics Wiper bearing.
The bear box bending stiffness is higher, however still makes with unstrengthened, cheap plastics.Can process with very simple slide block during fabrication.Because the structure of the structure of Wiper bearing and the mould that causes thus, except unstrengthened plastics, simply the raw material of withdrawing pattern also is suitable in principle as raw material, for example the plastics of Jia Qianging or die cast metal material, particularly zinc, magnesium, aluminium.
Ring-type element does not have with axle journal with being connected and is arranged on the bear box, thus can so that flexural load basically away from axle journal.Ring-type element on bear box, at least in a join domain can from the outside touch axle journal by pole with strut fixation in addition, and the thin plate pipe is connected with axle journal in this join domain.On the one hand preferred use go up lower fulcrum bar fixedly realized the rigidity that ring-type element-supporting rod device is high, both simplified the manufacturing of Wiper bearing on the other hand, also simplified being connected of thin plate pipe and axle journal, mould can touch simply from the outside because axle journal for corresponding mould, for example curls.
If ring-type element is arranged in the front of axle journal in the axial direction, particularly on its end face, do not have overlappingly with axle journal, this Wiper bearing can be made with the mould that does not preferably have toroidal cores and a kind of corresponding simple and firm sliding mould so.This has also realized mold cools down better in preferred die casting or Shooting Technique and core cooling.If axle journal stretches into ring-type element with an end in a kind of replacement scheme, the hollow profile core can carry out withdrawing pattern with toroidal cores on identical direction so, is unique sliding mould of these needs.
If axle journal is arranged in roughly middle with respect to the axial length of bear box, so this ring-type element supporting on bear box broad, and only occur very little warpage when cooling off after manufacturing on the member, this has just brought high geometry quality and good technological ability.Scheme as an alternative, axle journal also can for example be arranged in the lower end of bear box with respect to the axial length arranged off-centre of bear box.Can be implemented on the bear box thus and support widely.
When axle journal had hollow cross-section, the rigidity of Wiper bearing can be big especially.This rigidity of structure is big especially.Can aligning direction for the mold core of this hollow profile necessity, make it on the direction of axle journal, can be drawn, just be used for the manufacturing of ring-type element simultaneously with the ring mould core.The cross-sectional plane of this axle journal of scheme with a T type beam or double-T shaped girder construction as an alternative.Connecting geometric configuration can be with two mold half manufacturings or withdrawing pattern.This mould structure is simple especially.
Can be during particularly preferably in manufacturing with the member geometric configuration side direction withdrawing pattern between ring-type element and the bearing position.This has simplified the mould except recited above, can also after on the thin plate pipe box it be surrounded, so that effective a kind of preferred so-called the curling of this thin plate is connected with axle journal.Guaranteed that thus form fit good between thin plate pipe and the axle journal connects and special quality connects.In this thin plate pipe plastic deformation, and be pressed into for this reason in the groove of the Wiper bearing housing that is provided with or axle journal.Can use general curling mould.
