Definitions
- the invention relates to a joined multiple cam consisting individual prefabricated cams for an adjustable camshaft in particular according to the preamble of Patent claim 1.
- the invention relates to the problem of designing multiple cams composed of individual cams so they can be manufactured more easily, in particular with respect to multiple cams for adjustable camshafts.
- These adjustable camshafts are those which consist of two shafts mounted concentrically one inside the other, namely an inner shaft and an outer shaft whereby a generic multiple cam is mounted rotatably on the outer shaft and is rigidly pinned to the inner shaft via a radial opening in the outer shaft.
- the present invention offers the advantage of being able to perform the pinning exclusively within an area of the carrier pipe.
- the material of the camshafts which is designed for high stresses, may be limited to these elements, whereas the areas of the multiple cam which serve on the one hand as spacers between the individual cams and on the other hand as abutments for the pinning may be made of another material, in particular a material that can be made available less expensively.
- FIGS. 1 through 10 each shows different embodiment in a longitudinal section, a front view and a perspective view of a multiple cam.
- the respective multiple cam comprises two individual cams, namely a first individual cam 1 and a second individual cam 2 , which are joined together in different axial positions with a fixed rotational angle via a carrier pipe 3 .
- a first individual cam 1 and a second individual cam 2 which are joined together in different axial positions with a fixed rotational angle via a carrier pipe 3 .
- All the multiple cams illustrated in the drawing and described below are intended primarily for an adjustable camshaft (not shown in the drawing) in which they are mounted on an outer shaft and are fixedly pinned to an inner shaft situated coaxially inside this outer shaft.
- the areas in which the shaft is pinned via a pin 4 are situated between the individual cams 1 , 2 in an area of a carrier pipe 3 .
- FIG. 1 A first figure.
- Two individual cams 1 , 2 are joined together by a carrier pipe 3 .
- a carrier pipe 3 At the axial center of this carrier pipe 3 there is a ring collar 5 protruding axially outward.
- a individual cam 1 , 2 is placed on the end areas of the carrier pipe 3 which have a smaller diameter and each of which has a circular outside, and the individual cam is fixedly connected to the carrier pipe 3 by a press fit.
- the press fit may be reinforced by an adhesive bond between the individual cams 1 , 2 and the carrier pipe 3 .
- the axial distance between the individual cams 1 , 2 is determined by the ring collar 5 .
- the individual cams 1 , 2 may be mounted on the carrier pipe 3 with predetermined angles of rotation so that such a multiple cam can be placed on the outer shaft of an adjustable camshaft in a finished machine form and then in the ideal case need not be reworked anymore.
- Different materials may be used for the individual cams 1 , 2 on the one hand and the carrier pipe 3 on the other hand.
- the individual cams 1 , 2 may also be made of different materials if different operating stresses act on the camshaft for these individual cams 1 , 2 .
- the multiple cam For mounting such a multiple cam, which is mounted on the outer shaft in the case of an adjustable camshaft, the multiple cam may be pinned to the inner shaft radially through the area of the ring collar 5 .
- Such a type of pinning is illustrated in FIG. 8 in particular.
- This embodiment differs from that according to FIG. 1 essentially in that the carrier pipe 3 ′ does not have an outer ring collar 5 .
- the mounting of the individual cams 1 , 2 on the carrier pipe 3 , 3 ′ or all the other carrier pipe embodiments described below in any desired type of connection may consist of the possibilities with which those skilled in the art are familiar.
- the individual cams 1 , 2 may be connected to the carrier pipe in a press fit by welding, soldering, gluing and/or by a form-fitting connection.
- a carrier pipe 3 ′′ is used, its outer ring collar 5 ′ being shaped out of the carrier pipe 3 by molding the carrier pipe 3 ′′ in a high-pressure internal molding process, for example.
- the carrier pipe 31 has an inside circumferential area where the diameter is widened.
- such a widened inside diameter area has the advantage that when joining the multiple cam on the outer shaft of an adjustable camshaft, a manufacturing-related burr on the inside circumference of the ring collar 5 cannot have an interfering effect on the radial bore in the ring collar 5 ′ through which the pinning may be accomplished.
- a carrier pipe design may also be provided by machining a carrier pipe 3 out of solid material.
- a carrier pipe 3 ′′′ does not pass through the internal circumferential areas of the individual cams 1 , 2 .
- This carrier pipe 3 ′′′ is instead mounted essentially only axially between the individual cams 1 , 2 .
- ring grooves 6 that are open toward the inside radially are provided on the inside edge of each adjacent end face. In the area of these ring grooves 6 , the individual cams 1 , 2 each extend beyond the carrier pipe 3 ′′′ in the respective areas of the ring grooves 6 .
- the connection between the individual cams 1 , 2 and the carrier pipe 3 ′′′ may be established in the usual way alternatively or cumulatively by welding, soldering, gluing or providing a press fit.
- the carrier pipe 3 IV used here is one which is provided with a ring flange 7 protruding radially outward on one axial end.
- a spacer ring 8 also placed on the carrier pipe 3 IV , serves to maintain the space between the two individual cams 1 , 2 placed on this carrier pipe.
- a pin On the end of carrier pipe 3 IV opposite the ring flange 7 , a pin may be inserted through radial bores provided there in the carrier pipe 3 IV .
- the bores for the pin 4 may be arranged in the axial direction of carrier pipe 3 IV in such a way that they engage in the area of an adjacent first individual cam 1 , 2 .
- the respective individual cam 1 , 2 is provided with grooves 9 which run radially and are assigned to the bore for the pin 4 .
- the engagement of the pin 4 in these radial grooves 9 yields a twist-proof form-fitting connection between pin 4 and the adjacent individual cams.
- Axial bracing of the individual cams 1 , 2 , including the spacer ring 8 may also be achieved through the pin 4 by means of a corresponding orientation in the axial direction of carrier pipe 3 IV .
- the carrier pipe 3 V is part of one of two individual cams 1 , 2 . Fastening of the individual cam 1 and/or 2 , which is not a fixed part, on this carrier pipe 3 V is accomplished in the manner already described in conjunction with the other exemplary embodiments.
- This embodiment of a multiple cam that has been assembled and joined differs from that in FIG. 5 only in that the carrier pipe 3 IV here is joined to the individual cams 1 , 2 and is designed at both ends in the manner of the embodiment according to FIG. 5 with the help of pin 4 .
- a part of a carrier pipe 3 VII is integrally molded on each of the two individual cams 1 , 2 .
- the integrally molded parts of the carrier pipe 3 VII are designed so that they can be telescoped one into the other.
- the pin 4 may be passed through the telescoping individual areas of the carrier pipe 3 VII . After the pinning has been accomplished, the individual cams 1 , 2 are exclusively aligned and secured with respect to one another by this pinning.
- the two individual areas of the carrier pipe 3 VII emanating from the individual cams 1 , 2 may also be joined together according to one of the options given above for the other types of connection, i.e., in particular they may be joined together by welding, soldering and/or gluing.
- This embodiment variant corresponds to that according to FIG. 2 with the difference being only that the carrier pipe 3 VIII protrudes axially beyond the individual cams 1 , 2 at its ends.
- the carrier pipe 3 IX is a fixed part of the individual cams 1 , 2 .
- This multiple cam may be originally shaped in this form, reshaped or manufactured by machining.
- the radial inside circumference of the carrier 3 IX has a slightly enlarged inside diameter in comparison with the adjacent individual cams 1 , 2 .
- This area having an enlarged inside diameter offers the advantages already discussed in conjunction with a carrier pipe 3 having a similarly enlarged inside circumference in the embodiment according to FIG. 3 .
