Description
Technical field
The present invention relates to a kind of mechanical stretcher of the traction mechanism drive for internal-combustion engine, it is with substrate, substrate is provided with spiral spring, spiral spring prepares for power is applied to tensioning rail, so that the tensioning haulage gear when tensioning rail deflects, such as continuous haulage gear, as chain or belt.
Background technique
By the known traction mechanism drive of prior art, it is used in Motor Vehicle, such as, in passenger vehicle, load-carrying vehicle or other commerial vehicles.Therefore DE102010018204A1 such as discloses a kind of traction mechanism drive with spiral spring and independent damping member.Therefore the traction mechanism drive had for the internal-combustion engine with haulage gear is described, it is with the stretcher of the tensioning rail making haulage gear deflect with the deflection of generation tensioning rail, wherein, stretcher is configured to spiral spring, wherein, the independent damping member for the motion of damping tensioning rail contacts (Wirkkontakt) with spiral spring effect.Tensioning rail can be arranged pivotally relative to internal-combustion engine.
In order to realize the deflection of tensioning rail along the arrow A direction in the Fig. 1 shown in DE102010018204A1, stretcher contacts with tensioning rail effect.But stretcher itself is configured to spiral spring.
Spiral spring has inner section, and it is fixed on from the protruding pin of substrate protrusion.Substrate is fixed on internal-combustion engine itself.The inner section of spiral spring is fixed on protruding pin by positive.At this, inner section is embedded in the recess of protruding pin.Spiral spring has the surface of convex and the surface of spill.Be mounted with damping member between which.Damping member is shaped with the shape complementarity constructed by spiral spring at this.The damping member contact surface of convex and the surface of spill, and damping member extends near the inner section of spiral spring from the foreign section of spiral spring.The haulage gear stretcher of mechanical type pretension can be used widely, but especially design ap-plication in internal-combustion engine.The tensioning rail of haulage gear stretcher and corresponding enforcement is synchronous for what guarantee between one or more camshaft and bent axle in combination, this is because always at least there is required minimum chain tension when each motor rotary speed.
In addition, chain tensioning device should the vibration that may occur in damping traction mechanism drive/haulage gear, and the stretching that the wearing and tearing that must compensate chain cause.
The advantage of mechanical stretcher is in principle, with when hydraulic tensioner differently, the installation on motor can not rely on fuel feeding circulation loop completely.In addition need not consider the hydraulic slip occurred there, alleviate the load of oil pump thus.In addition the safety check of current limliting is not needed.Therefore, huge cost can be saved when hydraulic tensioner being replaced by mechanical stretcher.
Should provide cheap stretcher, it simply can assemble and show efficient especially.Stretcher especially should carry out pretension by tensioning rail and control chain, and makes haulage gear keep tension thus.In addition target realizes between bent axle and a camshaft or between bent axle and multiple camshaft minimum phase shift.In addition, the pretightening force of stretcher on working zone should keep constant as far as possible.
If there is resonance point when the specific rotating speed of internal-combustion engine, so this causes chain vibration usually.The vibration of haulage gear should pass through the damped with the rubbing contact of inside of the outside of clamping system, and therefore guarantees the function of whole system.Finally, should eliminate or at least reduce by the known shortcoming of prior art.
Summary of the invention
According to the present invention, this task solves as follows in by the stretcher of generic, that is, the end of spiral spring has the slide be made up of the material of (carrying out collision) damping, contacts to be formed with tensioning rail.
Favourable mode of execution is claimed in the dependent claims and set forth subsequently.
Therefore advantageously, slide positive and/or force closure ground pushing sleeve (aufschieben) or clip on the end of the tensioning trackside of spiral spring.Pushing sleeve or clip also can combine.At this advantageously, slide is first by pushing sleeve, and a part for spiral spring is taken in the corresponding pocket portion of slide, to connect via clip subsequently and finally to locate.
In addition advantageously, slide comprises plastics, such as polyamide, as PA46, PA66 or comprise teflon-polyamide compound or be made up of it.Not only can improve damping characteristic by these materials and also can improve the wear resistance between single parts simultaneously.
When slide has the protruding pin preferably cracked, slide can assemble simply and be firmly held in there simultaneously, and protruding pin matches, and is preferably pressed in the hole of spiral spring.
The feature of favourable embodiment is also, protruding pin to have for positive from the side concave surface of rear interlocking spiral spring material.The combination of spiral spring and protruding pin can be improved thus.
Especially desirably, substrate forming is the deep-draw sheet material of steel, and/or spiral spring is built by spring steel.Can reduce cost when deep-draw sheet material is used as substrate, wherein, it is cheap especially and durable that spring steel spiral spring is proved to be equally.
When substrate has protruding pin, by sealed for the end shape away from tensioning rail of spiral spring and/or force closure are fixed, such as, extrude and spiral spring is located, that is, being fixed on internal-combustion engine.So the characteristic of tensioning rail can be predicted well, and pre-determines in the design.
For variability when mounted advantageously, protruding pin is configured to hollow protruding pin, and limits hollow cavity, and it prepares for holding retention mechanism, as bolt/centre bolt or rivet.Additionally or alternatively, other hole may reside in substrate, to hold alternative or additional retention mechanism, as bolt, rivet or pin.Substrate with base part can be located regularly relative to internal-combustion engine.
When there is base (spiral spring is at least positioned on base) that be integrally connected with protruding pin and base part between the protruding pin and the base part of substrate of substrate range selector, stop or at least reduce the friction between spiral spring and base part.So the possible spring force be finally applied on tension spring does not reduce.This is conducive to efficiency.
Also advantageously, protruding pin exists groove or depressed part away from the side of base part, the bolt of lid (as deep-draw sheet material lid) is embedded in groove or depressed part, in order to make lid relative to base part anti-torsion.
Finally, the present invention also relates to a kind of traction mechanism drive, its with tensioning rail and by tensioning rail deflection haulage gear, wherein, tensioning rail with act synergistically according to the mechanical stretcher of type of the present invention.
In other words, the mechanical chain tensioning device optimized in manufacture cost is provided.Because the contact between slide and tensioning rail forms required damping, to eliminate the dynamic excitation coming from chain transmission.The hyoplastron be bent upwards of substrate, that is, the hyoplastron be bent upwards of the overall constituent element of base part can be used as bullet protection at this
Advantageously, the end in the face of tensioning rail of spiral spring or the external frame in the face of tensioning rail of slide have curved part, and it is matched with the arching portion of tensioning rail, thus the surface pressure between slide and tensioning rail is minimized.Be proved to be it is suitable that at this, between the external frame of convex determined in the end by slide and tensioning rail and the arching portion of the spill of tensioning rail, have 0.8 to 0.99, the preferably radius ratio of 0.85,0.90 or 0.95.
