Definitions
- the invention relates to a control timing for an internal combustion engine as such serves to adjust the phase position of the valve actuating portion of a valve train, in particular a camshaft, with respect to a power train upstream in the power train section.
- the invention relates here to a seated on a camshaft timing control device by which the phase position of the camshaft with respect to a designed as a timing chain or toothed belt traction drive can be changed.
- This timing control device comprises a hub element for mounting on a journal section of a camshaft and a surrounding outer housing.
- This outer housing is pivotable with the interposition of an adjusting mechanism relative to the hub member about an axis concentric with the camshaft axis.
- the adjusting mechanism is in this case designed as a vane cell mechanism with a plurality of control cells, so that a required pivoting of the outer housing relative to the hub member is achieved by appropriate oil pressure loading of the control cells of the vane cell mechanism.
- a sprocket is mounted with a timing chain is engaged.
- a hub element which has a seating area provided for attachment to a camshaft end section
- This Steuer concernsstellvorraum is characterized in that on the plate member, an insert portion is formed, which is insertable into a recess formed in the hub member, and that in the region of the insert portion at least one anchoring structure is formed by which the insert portion provided on a by the hub member counter structure is anchored.
- the anchoring structure is designed such that by this axial securing of the plate member is achieved on the hub member.
- the anchoring structure is further designed such that an anti-rotation is accomplished by this.
- the recess formed for receiving the insert portion of the plate member in the hub member is preferably designed as a substantially cylindrical, or slightly conical countersink or bore.
- the Ab- mood of the outer dimension of the insert portion and the dimensioning of the inner diameter of this sinking is preferably accomplished so that the insert portion sits under a slight interference fit in the sinker.
- the anchoring structure can be made by local, plastic deformation of the insert section. This local, plastic deformation can be achieved, in particular, by means of suitable stamping elements which dive into the interior region of the insert section during the assembly of the control timing adjusting device. It is also possible to design the anchoring structure in such a way that the anchoring structures which act as pull-out or anti-rotation locks are formed by elastically deflectable sections of the plate element or of the insert section thereof. In this respect, these elastically deflectable sections form with at least one edge region behind-grip structures which latch onto a corresponding, for example provided by a groove, counter wall of the hub element.
- the structures formed to achieve the anti-rotation lock on the insert section of the plate element can be embodied in particular as web or nose sections which bulge radially in a section plane radial to the camshaft axis.
- the rear grip structure which acts to achieve the axial pull-out protection and possibly also additionally acts as an anti-rotation device can also be designed as a radially extending pawl, nose or claw.
- the insert section arranged on the plate element is preferably designed as a pot structure.
- the rear grip structures integrally formed on this pot structure can, in particular, engage with counter-structures formed as a groove or pocket formed on the hub element. These engagement structures can be made in particular by punching horseshoe-shaped recesses in the peripheral wall of the insert section.
- the tongues thus formed can be bent outward by a certain angle. When inserting the insert portion of the plate member in the corresponding receiving bore these tongues or claws are initially deflected radially inwardly and then lock due to their inherent elasticity when reaching the required mounting position in the corresponding complementary geometries of the hub member. The tongues are pressed inwards by the edge of the Rotorzentrierbohrung. Once the trigger plate / spring plate has reached its end position, the tongues snap into the groove provided by means of their spring preload and spread. Pulling out the plate is now no longer possible.
- FIG. 1 is an axial sectional view for illustrating the construction of a control timing adjusting device according to the invention with a spring plate secured thereto in a form-fitting manner;
- FIG. 2 likewise an axial sectional view for illustrating the installation situation of a control timing adjusting device according to the invention on a camshaft
- FIG. 3 shows a simplified sectional illustration for illustrating the engagement state of a disk element according to the invention on the hub element of a timing adjustment device
- FIG. 4 a sketch to further illustrate the construction of a preferred variant of the insert section of the plate element
- FIG. 6 shows a schematic representation for illustrating a further variant according to the invention for at least axial securing of a nes plate element on a hub member of a timing control
- Figure 7 is a sketch to illustrate the design of the insert portion of the plate member before insertion thereof into the associated receiving bore portion of the hub member.
- the timing adjustment device serves to adjust the phase position of a camshaft of a valve train relative to the camshaft drive train according to need.
- the timing control device comprises a hub member 1, which has a provided for attachment to a Nockenwellenstirnabmale seating area 1 a.
- an actuating mechanism 3 which is not further illustrated with regard to its constructive details and which serves to effect the pivoting of the outer housing element 2 relative to the hub element 1.
- the timing control device shown here is characterized in that on the plate member 4, an insert portion 4a is formed, which is inserted into a, formed in the hub member 1, 1 b recess, wherein in the region of the insert portion 4a at least one anchoring structure 6 is formed by which the insert section 4a at one by the Na Benelement 1 provided counter structure - here Inner functioningsnut 7 - is anchored.
- the anchoring structure 6 is designed such that at least one axial securing of the plate element 4 on the hub element 1 is achieved by the latter.
- This anchoring structure can, as will be explained in more detail below, also be designed so that it is accomplished by this rotation of the plate member 4 in the circumferential direction.
- the sinking 1 b is executed in this embodiment as a substantially cylindrical bore, in which the insert portion 4 a of the plate member 4 is received with a slight interference fit.
- the anchoring structure realized here, it forms a plurality of projections protruding radially outward and thus undercut in the direction of extension in cooperation with the circumferential groove 7.
- the anchoring structure can - as done here - be designed as elastically deflectable rear handle structure, in particular with radially outwardly bulging pawl, claw or nose sections. Alternatively, or in combination with this measure, it is possible to realize the anchoring structure 6 by local, plastic deformation of corresponding areas of the insert section 4a.
- the rear grip structure 6 is formed by a plurality of pawls 8 extending radially outwards. The cooperating with this pawl 8 counter-structure is, as already mentioned, designed as a circumferential groove 7.
- the plate element 4 is formed by in the region of the insert portion 4a formed on this, radially outwardly extending pawls 8 in a this trained, outwardly radially extending pawls 8 anchored in a corresponding circumferential groove 7, or Eingrifsstaschen the hub member 1.
- driving grooves 12, 13 in the region of the circumferential wall U2 receiving into the insert section 4a.
- driving lugs 14, 15 engage.
- driving lugs 14, 15 and in particular also the complementary geometries designed to prevent rotation in the hub element 1 can also have other cross-sectional geometries.
- the securing structures provided for realizing an anti-twist protection of the plate element 4 are provided in combination with axial securing structures, as they are in their Structure may correspond, for example, the embodiments described above.
- FIG. 6 shows a further variant of a securing concept according to the invention for securing a disk element 4 on a hub element 1 of a timing adjustment device.
- the anchoring structures 6 provided for realizing an axial securing are created by radial bending out of tongue sections 8b.
- This radial bending out of the tongue sections 8b can take place, for example, by means of a stamping tool 16, which is merely shown by way of example here in its basic construction.
- this stamping tool 16 comprises a stamp jacket 17 and a stamp core 18, wherein disengagement slides 19, 20 can be actuated via the stamp core 18.
- FIG. 7 shows a preferred embodiment of the insertion section 4a, which as such is provided with cut-free tongue sections 8b.
