Utility model content

Therefore, the purpose of this utility model is to propose a kind of device for adjusting camshaft, and it can realize saving and install The camshaft support of space but long lifespan, and allow accurately to adjust control time.

Camshaft adjuster is used for internal combustion engine, and the camshaft adjuster has drive motor and is placed in after drive motor Transmission mechanism, and with for being attached to the connection section of the camshaft of internal combustion engine, the transmission mechanism is with being used for being attached to leading Draw the connection parts of mechanism, the haulage gear is driven by the driven shaft of internal combustion engine, it is characterised in that transmission mechanism and connection section By on the one hand anti-torsion and on the other hand radial compliance and/or can the transferring element of axial bending rotationally fixedly mutually interconnect Connect, or directly by the one hand anti-torsion and on the other hand radial compliance and/or can the transferring element of axial bending resist Rotatably it is connected with each other.

Recognized for the first time using mode of the present utility model, such as by camshaft adjuster known in the art not only Only produce the moment of torsion for adjusting camshaft and transmit the moment of torsion rotated for camshaft, but also so that camshaft and cam The power that axle bearing bears load is delivered on camshaft.The producing cause of the power is, camshaft adjuster is mostly and hauling machine Structure couples, and by the haulage gear, these are applied loaded power enduringly and are repeatedly delivered to camshaft adjuster and convex On wheel shaft and camshaft bearing, it causes the bending of particularly camshaft.In the area that camshaft adjuster couples with camshaft In domain, there is the radial vibration for particularly forcing in camshaft, and this vibration causes that camshaft and its camshaft bearing constantly hold Loaded.Therefore, king-sized camshaft bearing must be especially selected, shaking for this radial direction is enduringly tolerated so as to it It is dynamic.

In order to avoid camshaft bearing is loaded caused by because being delivered to the power on camshaft by haulage gear, according to this Utility model specifies that transmission mechanism and connection section are particularly directly through on the one hand anti-torsion and on the other hand radially soft Property and/or can the transferring element of axial bending be rotationally fixedly connected with each other, be achieved in camshaft and depart from above-mentioned power.

Can particularly advantageously provide for, transferring element is delivered to connection by design from the cross force without radial direction On section, particularly it is not transferred to the cross force of the radial direction of camshaft adjuster from haulage gear and is delivered on connection section. Can also specify herein, transferring element causes that couple section departs from the cross force of radial direction, particularly passes with via haulage gear The cross force for being handed to the radial direction of the connection parts of camshaft adjuster departs from, and/or, transferring element is acted as relative in the axial direction Design moment of torsion anti-torsion.Here may further specify that, transferring element is constructed in the axial direction and/or radially elastically. The advantage of these implementation methods is that the radial direction for being transferred to camshaft remainder that the union end of camshaft is not forced is shaken It is dynamic.

Transferring element especially can with-alternatively or additionally-by design, from the cross force without radial direction from connection Section is transferred to the remainder of camshaft adjuster and/or is transferred to haulage gear.Thus, in this type of design, it is convex The part taken turns the remainder and haulage gear of shaft-type governor and couple thereon all effectively undergoes to be protected against because of footpath To the extended load that the camshaft of vibration causes.

Transferring element can be advantageously designed to one side radial compliance and/or transverse to axially flexible and another The connector of one side anti-torsion.The measure is taken by so that camshaft is effectively transported with the radial direction implemented by camshaft adjuster It is dynamic to depart from, it is delivered on camshaft from camshaft adjuster without negatively affecting moment of torsion.

According to this design, connector is designed to the shaft coupling or Austria of claw connector or stacked connector or flexibility Er Demu connectors or folding levelling connector.

Stacked connector is particularly advantageously used, because it has less component just enough due to construction reason .Especially, different from such as Oldham connector, for stacked connector, it is not necessary that moveable component Place with sliding relative to one another.

Transferring element can also for example be configured to the driven vault cover (Abtriebsglocke) of tank shape.In the utility model Meaning under, term " driven vault cover " refers to such as lower member：It is suitable for and is arranged for moment of torsion from camshaft adjuster It is delivered on camshaft, wherein, driven vault cover not necessarily has the shape of traditional vault cover such as church formula vault cover.For example, Driven vault cover can also be configured to tank shape and/or asymmetricly construct.Driven vault cover can with but not necessarily symmetrically structure Make.Driven vault cover can also for example have spoke (Speiche) that is multiple, at least partially radially setting.Especially, driven vault Cover will not necessarily have the wall of closure.But so it is favourable.

However, the design of the rotationally symmetrical formula of driven vault cover, the particularly design of tank shape or traditional vault bell-type design are special It is favourable because, this design can avoid it is unbalance, no matter also, radial direction and/or axial direction the power to be born rotation position Put and all to cause same deformation how all the time.

By the driven vault cover of tank shape of preferred flexible and anti-torsion, the camshaft of connection is enduringly protected, from Fortune is waved because radial direction and/or axial direction the oscillating movement of the connection section of the camshaft adjuster coupled with camshaft is particularly The dynamic infringement for causing.
