Description
Technical field
The present invention relates to guide rail or tensioning rail, the traction mechanism drive with the haulage gear as chain or belt that is used for internal-combustion engine, has carrier, this carrier has the first side that faces haulage gear and the second side that deviates from haulage gear, wherein, passage passes carrier and extends from the first area of second side to second area with interval.
Background technique
Tensioning rail or guide rail are used in the internal-combustion engine, especially in the situation of controlling run.Use these tensioning rails or guide rail to be used for the haulage gear of tensioning as chain or belt.Haulage gear, namely circulate haulage gear it self driven by bent axle after, drive the axle of one or more camshafts and/or auxiliary unit.Such guide rail or tensioning rail often are fabricated to aluminum die casting section bar or plastic material, the plastic material of especially for example strengthening by means of glass fibre.PA 66 materials of strengthening with or without glass fibre demonstrate advantage in some special applications.
The geometrical shape of internal-combustion engine recently becomes and becomes increasingly complex, and therefore just is necessary, also keeps in advance and the incoherent installation passage of effect by such guide rail or tensioning rail.These install passage should be applicable to additional purpose, especially is applicable to the guiding of passing through of oil dipstick.
By existing technology, namely in EP 1 561 968B1, provide a solution to this.A kind of equipment for internal-combustion engine is disclosed there, have for driving mechanism flexibly, be particularly useful for the Quality Initiative of motor of the internal-combustion engine and be in tensioning rail or the guide rail of the member in the interactively with motor of the internal-combustion engine, wherein, tensioning rail or guide rail comprise carrier and can be pressed to guide rail (F ü hrungsbahn) on the driving mechanism flexibly, driving mechanism contacts with guide rail flexibly, passage is installed at its peripheral surface sealing ground structure, this installation channels configuration has the first end of opening wide and the second end of opening wide, and the member that is in the interactively with motor of the internal-combustion engine extends by passage is installed at least regionally, wherein, tensioning rail or guide rail comprise and the incoherent installation passage of guide rail effect in addition, the wall that passage is installed forms by carrier, and the first end of opening wide and the second end of opening wide are arranged in the opposite each other on distolateral end of tensioning rail or guide rail.
Summary of the invention
Yet the weight of guide rail or tensioning rail should be further reduced, and assembling should be easier, and especially should avoid the high assembling of cost and should utilize efficiently existing structure space in the situation of the motor geometrical shape of complexity.
This reaches in the following way according to the present invention, that is, passage designs in face up conversion side opposite each other with opening wide.
According to this mode, passage can remove by means of the material of side (Entformung) and is made by cost-effective ground.Need carrier material still less, so carrier and guide rail or tensioning rail become lighter thus.
The effect that this also has fuel consumption, this is again favourable.Because be used for cost of upkeep and the operating cost of the internal-combustion engine of corresponding traction mechanism drive (this traction mechanism drive has according to guide rail of the present invention or tensioning rail) lower than comparable internal-combustion engine.
Such guide rail or tensioning rail especially are provided for the use with oil dipstick or oily gauge, because no longer need extra structure space to be used for the guiding of this dipstick.
The in the dependent claims prescription of favourable mode of execution and subsequently in detail explaination.
Therefore advantageously, the design of carrier single part formula ground or the design of carrier two component type ground, wherein, passage is in the separating plane that separates these two parts.In the design proposal of single part formula, assembly cost is lowered in particular.
When passage when only section ground is to the first side that connects first side and second side or the second side-closed by the contact pin of carrier, kept guiding function with being guaranteed.When a plurality of contact pin are overlapping, be favourable.
When the contact pin of relative the second side of the contact pin of the first side is staggered, also be favourable.In this deformation program, although few especially materials demand has guaranteed guiding function.
Prove and particularly advantageously be, contact pin has stretching, extension at the longitudinal direction of passage, and this stretching, extension is less than the stretching, extension in the space (Leerraum) of the sky between contact pin of observing at the longitudinal direction of passage.So the result is exactly light especially and Weight-optimised guide rail or tensioning rail design proposal.
When contact pin and empty space are measured in this wise, that is, obtain perpendicular to/be orthogonal to two sides through holes orientation, from the first side to the second side, so then guide rail or tensioning rail are Weight-optimised especially.Manufacturing also is simplified thus especially, and economic manufacturing can realize thus.
In addition advantageously, passage is curvedly constructed, and extends along the longitudinal direction of guide rail or tensioning rail haply.
Other favourable mode of execution is characterised in that the first side of design carrier is used for reclining of haulage gear or is used for holding of its sliding layer, and wherein, sliding layer itself is designed for reclining of haulage gear.
When passage has cross section rectangular, that preferably be square, be favourable.
The present invention also relates to the traction mechanism drive with the circulation haulage gear such just like chain or belt, with guide rail or the tensioning rail in aforesaid foundation design proposal of the present invention.
Description of drawings
The present invention does further explaination by means of diagram.In these diagrams, the first embodiment has been shown.
Wherein:
Fig. 1 shows the first according to the perspective view of guide rail of the present invention; And
Fig. 2 shows the view from dorsal part by the foundation guide rail of the present invention of Fig. 1.
These accompanying drawings only be illustrative nature and only be used for understanding of the present invention.Identical element will be provided with identical reference character.
Embodiment
Guide rail 1 has been shown among Fig. 1.This guide rail 1 also can be configured to tensioning rail.This guide rail 1 for haulage gear, be that chain or belt reach and contact, be configured to the parts of the traction mechanism drive of internal-combustion engine.
This guide rail 1 has carrier 2.This carrier 2 has the first side 3 that faces haulage gear and deviates from the second side 4 of haulage gear.Passage 5 extends through the carrier 2 of single part formula design.Carrier 2 also can design on multi-part formula ground, especially can design on two component type ground, and wherein, passage 5 is in the separating plane of carrier 2, and wherein, this separating plane is separated from one another with two parts of carrier 2.
Passage 56 extends to second area 7 from the first area.First area 6 and second area 7 are on the second side that deviates from haulage gear 4 of carrier 2.First side 3 are connected with the second side by the first side 8 of distributing spaced in parallel to each otherly be connected side 9 and connect.The first side 8 is that leading flank and the second side 9 are trailing flanks.
Be provided with the each other contact pin 13 of equi-spaced apart in the first side 8 and the second side 9, these contact pin are separated from one another by empty space 14.Thus, observe at longitudinal direction 10, contact pin 13 and empty space 14 replace.When having a contact pin 13 in the first side 8, will on the second side 9, roughly have the space 14 of a sky at the same area place.But these empty spaces 14 are observed larger than contact pin 13 at longitudinal direction 10.
This causes, and is contiguous to and has through hole 15 in the contact pin 13 separately, and these through holes are perpendicular to leading flank and orientation posterolaterally, and passes whole carrier 2 ground and run through extension, in order to be thus connected the first side 8 and the second side 9.
