Description
Technical field
The present invention relates to a kind of tensioning rail for the towing gear on the internal-combustion engine, described tensioning rail has the carrier of being made by plate stamping spare, the sliding layer that is made of plastics is fixed on the described carrier, so that for the circulation haulage gear of described towing gear provides slip surface, wherein, described carrier has the hole, pivoting point is determined in described hole, described tensioning rail can pivot around described pivoting point, and is configured with supporting zone for the side at described pivoting point contacts with stretcher.
Background technique
By the known a large amount of tensioning rails of prior art, described a large amount of tensioning rails are applied in the scope of towing gear, and described towing gear uses circulation haulage gear such as chain or belt.In most cases, this towing gear couples together at least one bent axle and second axle (such as camshaft or the live axle of auxiliary unit) of internal-combustion engine.
This tensioning rail can be can center on the mode deflection that pivoting point pivots, so that the elongation of compensation cycle haulage gear.For reaching this purpose, tension element namely stretcher acts on the one side of tensioning rail, and when emitting, tensioning rail pivots around pivoting point.Then the haulage gear that circulates slides at the face of tensioning rail.
In order to keep hanging down friction, in sliding layer, this sliding layer is positioned between circulation haulage gear and the tensioning rail in this plastic applications that frictional force is especially little.So tensioning rail comprises carrier and sliding layer, wherein, slide mass is clamped on the carrier usually.
The carrier of previous tensioning rail is made of metal.This is for example known by DE 3049106 A1, DE2431425 and DE 19704899 C1.Two texts mentioning at first also disclose the carrier of being made by plate stamping spare, and the plastics sliding layer is clamped on this carrier.Yet the text of mentioning later discloses the support of being made by the plastic materials of making or metallic material in pressure casting method.
Recently use more and more the carrier that is made of plastics, for example roughly known by DE 202,007 019 176 U1, DE 20 2,008 012 354 U1 or WO 03/044392 A1.But by the EP 1306580 D1 also plastic guides of known pivot movement for transmission device.In this document, disclose a kind of movable, be used for flexibly around the plastic guides of energy transmission medium, wherein, this plastic guides has long extension guide way, this extension guide way is comprised of the sliding shoes of longitudinal extension, described sliding shoes have for the front and back of energy transmission medium sliding contact.Disclosed theme is characterised in that in the text, has dull and stereotyped housing region (this flat board housing region extends along the sliding shoes back side in the vertical), and has the slit with opening that extends longitudinally, this opening points to and the direction of pointing to the positive opposite direction that points to of sliding shoes, wherein, sliding shoes and dull and stereotyped housing region integrally are die cast as the unit by synthetic resin, this theme is characterised in that, also has stiffening plate, this stiffening plate cooperates in the slit, wherein, guide way and stiffening plate can be supported pivotally around fixing part, the end of this fixing part and guide way is adjacent to layout, wherein, and dull and stereotyped housing region, the part that deviates from the described end of guide way consists of the plunger surface of contact, this plunger surface of contact can contact with the plunger of stretcher, the plunger surface of contact is separated by the opening in slit, and stiffening plate is in the slit, at least keep the position of interval plunger surface of contact to sink in the slit, thereby stiffening plate can partly not protrude from gap opening, the part of plunger surface of contact.
By CN 102086923, GB 200809687 and JP 2007040331 also known other tensioning rails.GB 200809687 discloses a kind of carrier of being made by aluminium material, yet wherein, this carrier is made in pressure casting method.The carrier of other two texts of just having mentioned neither be made by sheet material, but made by die-casting material.
DE 10 2,009 023 825 A1 also disclose a kind of guide rail and have been used for the guiding haulage gear, this guide rail has carrier and the slide mass that is arranged on the carrier, this slide mass is made of plastics, wherein, haulage gear is guided at slide mass, and carrier does not have curved part on its surface of contact of arranging facing to slide mass, otherwise slide mass has curved part at its slip surface towards haulage gear.
Summary of the invention
Task of the present invention is to provide a kind of improved tensioning rail.
Especially should reach more reliable operation of tensioning rail, and for example stop stretcher slippage and/or avoid haulage gear in the transversely slippage from this sliding layer of sliding layer from the carrier.
Should utilize the extraly mechanism of design, it can be made durable ground and make inexpensively tensioning rail.
This reaches as follows according to the present invention,, constructs guide rib at the edge of described carrier that is, and described supporting zone is present within the described guide rib.
So plate stamping spare can so be constructed, so that, at step of overall modelling (for example crooked) afterwards, the interlock ability that plate stamping spare has pivoting point, guide portion and is used for sliding layer.Guiding connecting sheet and the strong point that also can keep chain tensioning device, particularly, the size and dimension of tensioning rail mates with exploitation and the demand of the internal-combustion engine that wherein will use tensioning rail.
The claimed favourable mode of execution of dependent claims and following detailed description.
Advantageously, if, at least one guide rib be orthogonal to be in the contacting of described sliding layer in supporting surface, described guide rib extends towards the direction that deviates from described supporting surface.Can process the simple guide rib of making by crimping by this way.In addition, advantageously, at two guide ribs of each edge structure.Even when regulating tensioning rail, when namely pivoting around pivoting point, also keep getting rid of stretcher from the slippage of carrier.
When two guide ribs along described carrier vertically keep the interval each other the time, just can increase the protected field that prevents the stretcher slippage.
In addition, advantageously, if described guide rib has the convex surface shape.Thus, also reduce thus when mounted risk of injury.
In addition, when described hole exists only in the plate stamping material of described carrier, also make installation easier.The material that needs also seldom, this has reduced cost.
When concerning described guide rib extraly or alternatively, partly surround guide tabs sliding layer, described carrier be higher than sliding layer, deviate from carrier stretch out outwardly the time, then haulage gear (such as chain) can be led better, need not to preset additional director element at sliding layer.
When having a plurality of opposed guide tabs at the edge along described carrier longitudinal extension, then in two slippages that transversely effectively stop haulage gear of carrier.
When described guide tabs is stretched out from the supporting surface of described carrier orthogonally, can simplify manufacturing.
The present invention also relates to have the towing gear of foregoing tensioning rail, this towing gear has circulation haulage gear (such as chain) and has stretcher (such as chain tensioning device hydraulic pressure or machinery), and this stretcher can recline with supporting zone.
