Description
Technical field
The present invention relates to a kind of tensioning frame of the traction mechanism drive for internal-combustion engine, wherein, tensioning frame has the sliding layer of being made by the first material, it reclines side in order to contact haulage gear for example belt or chain with haulage gear, wherein, tensioning frame also has the carrier of being made by the second material, it is with deviating from the recline dorsal part of side of haulage gear, wherein, sliding layer is made of plastics and is fixed on the carrier, wherein, is configured with guide rail at the dorsal part of carrier, on described guide rail, can lay movably clamp, so that section supports with reclining of internal-combustion engine and make contacting that tensioning frame deflects.
Background technique
Traction mechanism drive is applied in the internal-combustion engine, is connected in order to set up the power transmission between bent axle and camshaft and/or jack shaft.So jack shaft can drive auxilitary unit, for example motor, generator or pump.
This traction mechanism drive is applied in the motor vehicle, and for example passenger vehicle, load-carrying vehicle also can be applied to aircraft, and other lands with or the water vehicle.
Usually, this traction mechanism drive also is applied in the trail bike.
So, in this traction mechanism drive, using tension device, described tension device is by means of the hydraulic tensioner pretension or by means of the mechanical tensioner pretension., uses by tension device the sort of stretcher that can be used in the different haulage gears for being deflected.In this way not only can the pretension chain but also can the pretension belt.
But hydraulic tensioner for example hydraulic chain adjuster has following shortcoming, that is, must be to its supply pressure medium, described pressure medium is oil machine oil for example normally.So, for corresponding oil supply, must provide corresponding pipeline, described pipeline is so that traction mechanism drive becomes heavier.Because the pressure medium pipeline also must bear very large pressure and must be correspondingly firm, just caused thus very high cost.
Lower-cost and to need the stretcher of the alternative of less annex be mechanical tensioner, for example known like that by EP0409460B1 and EP0869298B1.These mechanical tensioners come work or come work according to spiral system according to the lock pawl system.
But so-called lock pawl stretcher has following shortcoming, that is, it only can realize that grading type adjusts and can not realize that the stepless of tensioning frame adjusts again.But for haulage gear being deflected again and compensating thus the elongation that is caused by temperature and wearing and tearing, this electrodeless the adjustment again to tensioning frame is desired just.The feature of so-called lock pawl stretcher is that also very high member expends.
Usually, as the power screw stretcher of machinery and known solution causes very high member expense equally.
Two kinds of known mechanical tensioners all can not be used as system scheme, this means, independent tension element must be installed between independent tensioning frame and internal-combustion engine.This has caused the mounting cost that improves.
There has been the scheme that realizes system scheme, wherein, the tensioning frame that is comprised of two plastic type has been installed.But this tensioning frame that only is made of plastics is thermo-labile, and this is to change significantly because depend on temperature effect for plastics especially polyamide Young's modulus.
For example WO2010/040679A1 discloses a kind of tension device of the elongation for compensating haulage gear, it is with tensioning mechanism, wherein, be furnished with tension element between the supporting surface of tensioning mechanism and internal-combustion engine, wherein, tension element forms element of construction with tensioning mechanism, wherein, tension element is also in the guiding of the raceway of tensioning mechanism and be configured to clamp, and wherein, raceway presss from both sides into about 30 ° angle with respect to supporting surface.At this, carrier is the assembly of tensioning mechanism.Carrier serves as the acceptance division for sliding layer, and described sliding layer is fixed on the carrier by means of the kayser hook.At the dorsal part with respect to sliding layer, crooked linear raceway is positioned on the carrier, and described raceway is adjacent in the supporting surface of internal-combustion engine.Be furnished with movably clamp on raceway, described clamp has grapple, and described grapple hooks in the groove in the carrier on raceway next door.Be furnished with pressing spring between carrier and clamp, the one end is arranged on the mandrel that is fixed on the carrier place, and the other end is arranged in the interior opening of clamp.Mandrel has the chamfered edge (Anfasung) along mandrel, and it has simplified the installation of clamp.Inserted the locking inclined-plane in the surface of raceway, it effectively is connected with corresponding locking inclined-plane on the clamp.These lock the inclined-plane and allow simply haulage gear to be adjusted based on the power of pressing spring by tension device again, have stoped do not expect lax.Be processed with hyoplastron at clamp, described hyoplastron has hook, and described hook keeps being connected with pairing hook on the carrier in the following way, that is, clamp can be at inflow location and carrier grab.In order to guarantee that in the situation of all positions of clamp linearity clear and definite between clamp and the supporting surface contacts, clamp has the spherical surface of contact of implementing.Carrier can be made by different plastics with sliding layer.The raceway of clamp also can integrally be constructed at carrier.Be provided with the locking inclined-plane that matches each other at raceway and clamp, wherein, can select in the following way to lock the geometrical construction on inclined-plane, that is, clamp can be along one party to being fixed on the raceway.The support surface flat ground at internal-combustion engine place is implemented.The disclosure of being correlated with therewith of above-mentioned patent documentation should integrally be useful in here.
Following also is known, that is, also can use carrier made of aluminum and can have spring element between sliding layer and carrier.The solution that is comprised of multiple plastics has shortcoming aspect the Young's modulus, because its notable change under temperature effect, and the solution of this aluminium carrier has shortcoming aspect vibration compensation, because it only can the limited vibration of degree of compensation.In addition, also very limited for the structure space of spring element.
Similar prior art is also known by patent documentation GB2259954A, DE1750655U, DE19606002A1, DE908694B, DE19810486A1 and DE19923923A1.
