Description
Technical field
Integral type that the present invention relates to a kind of in combustion engine switching camshaft and driving for the switching camshaft
The arrangement of dynamic receiving portion, wherein switching cam shaft is used to axial passage and switches camshaft to can support with elapsing and have
Switching sliding slot, and switch that camshaft is axial in end regions to be supported in the receiving portion of axial restraint with elapsing.
Background technique
In order to change valve lift curve during combustion engine operates, and it therefore can adjust Combustion Engine
The best unlatching of each operating condition of machine and closing time, it is desirable to be able to during operation for each valve in multiple cam shapes
It is converted between shape.It is that this point can be elapsed conveniently by an axial direction, for each valve there are different cams to cut
Camshaft is changed to realize.
The arrangement of aforementioned type as known to 0 579 592 A1 of EP.The receiving portion of axial restraint is configured to rotatable herein
The sliding members of bearing switches cam shaft to that can be contained in elapsing in the sliding members, and wherein driving wheel is in a manner of flange
On (angeflanscht) sliding members, which is used to drive sliding members and therefore drives switching camshaft.
Summary of the invention
The object of the present invention is to the arragement construction of such improvement aforementioned type, so that (especially by the simple device of structure
It is very low part diversity) it is axially fixed in its switching position to ensure to switch camshaft.
The arragement construction of the with good grounds feature of the invention of this purpose apparatus is realized.
Arrangement of the invention has a lockable mechanism, is locked in different passage positions for that will switch camshaft.
Here, lockable mechanism is acted between switching camshaft and receiving portion.
In the operating of combustion engine, switching camshaft is rotated with revolving speed identical with receiving portion.Therefore convex when switching
When wheel shaft switches in its different switching position, the receiving portion that switching camshaft can not be elapsed relative to the axial direction is only had recorded
Axial passage.By particularly simple structure devices, particular by very low part diversity, this point can allow for cut
Camshaft is changed to be axially fixed in its switching position relative to receiving portion.
It is considered as particularly advantageously, switching camshaft is shape-ordinatedly supported in receiving portion.Switching camshaft is especially set
It is equipped with outer toothed portion, the outer toothed portion teeth portion complementary with receiving portion collective effect in the notched region of receiving portion.Accordingly, it accommodates
Torque between portion and switching camshaft is synchronous therefore in the form of teeth portion by shape cooperation realization.
If there is the lockable mechanism locking ball and locking to be recessed, which is configured especially in terms of construction
Simply.Here, locking ball pre-tightens on the direction that corresponding locking is recessed by a spring.Just in switching camshaft and appearance
It receives when portion rotates and acts on for the radial force on lockable mechanism, be considered as particularly advantageously, which is constituted in this way, i.e.,
Switching camshaft has a blind hole for being used to accommodate spring and locking ball, and switches camshaft in inner radial with lock
Only recess, especially two locking recess.The collective effect if spring-loaded ball and corresponding locking are recessed, switches convex
It is fixed on to axle axial in the relative position (it is subordinated to locking recess) of switching camshaft and receiving portion.If switching cam
Axis is axially adjusted by switching sliding slot, then locking ball comes out from locking recess, and wherein spring consumingly compresses, and locks
Only ball sticks on the locking recess for being subordinated to the on-position in the new switching position of switching camshaft.
If receiving portion has the pipe section of ring gear and co-axial setting, switch camshaft and drivable receiving portion
Being arranged in structure in its join domain be configured to it is extremely simple, wherein receiving portion can by ring gear from external drive,
Ring gear can be axially supported in switching camshaft with elapsing in inner radial, and pipe section has locking recessed in inner radial
It falls into.
In order to arrive at its different switching position, especially axially passage switches camshaft, and mode is: switching sliding slot tool
There are two sliding slot track, and in order to connect switching camshaft, setting there are two it is axial it is can elapsing, can be with corresponding sliding slot
The switching pin of track engagement.
Therefore, the present invention includes that its improvement project suggested a kind of switching camshaft and for switching driving for camshaft
Receiving portion arrangement, wherein integrally design switching camshaft, therefore it be configured in configuration aspects it is extremely simple.Torque is same
Step is realized on switching camshaft particularly by shape cooperation, wherein can also realize that the torque of force-fitting is synchronous in principle.It cuts
The adjusting for changing camshaft is realized particularly by two switching pins.Have extremely with the coefficient cam pair of valve of combustion engine
Few two different cam profiles for corresponding valve.Switching camshaft is remained in position by lockable mechanism, the locking
Mechanism is especially made of locking ball, spring and locking recess.Switching camshaft and receiving portion are rotated with identical revolving speed.
Detailed description of the invention
Other of the invention are characterized in obtaining in the description by dependent claims, attached drawing and the embodiment shown in that figure, but
It is not limited to the embodiment.It is shown in the accompanying drawings:
Fig. 1 shows the present invention arrangement of switching camshaft and drivable receiving portion in longitudinal sectional drawing, by cutting
The rotation axis for changing camshaft and receiving portion is splitted, and has the bearing additionally shown and switching pin；
Fig. 2 shows switching camshaft and receiving portion in space view；
Fig. 3 shows switching camshaft and receiving portion in detail view, and is in switching camshaft for the switching
