Definitions

  • the invention relates to a camshaft of in particular motor vehicle engines with a coaxially arranged in an outer shaft inner shaft which is rotatably supported against the outer shaft.
  • camshaft adjusters To reduce fuel consumption and pollutant emissions as well as to increase the power and the torque of many Otto engines are usually equipped with camshaft adjusters.
  • camshaft adjusters also known as phase adjusters, change the phasing of the camshaft relative to the crankshaft.
  • a camshaft adjuster for an internal combustion engine with an inserted into a camshaft control valve having a guided in a guide sleeve hydraulic control piston.
  • the actuating unit has an inner body fixedly connected to the camshaft and an outer body rotatably mounted to the camshaft, via which a drive connection extends from a crankshaft to the camshaft, and wherein the control valve is acted upon by an electromagnetic device and supplied with hydraulic medium via the camshaft.
  • an oil guide module is inserted, which serves at least for guiding the hydraulic medium between an interior of the camshaft and the control valve.
  • the disclosed camshaft is designed as a one-piece camshaft.
  • From the DE 44 15 524 A1 is a hydraulic actuator for changing and readjusting the valve timing of a crankshaft driven camshaft of an internal combustion engine known.
  • the rotational position of the camshaft is adjustable by a limited angle of rotation, wherein in a chamber seated wings are subjected to pressure medium.
  • the invention is concerned with the problem of arranging a camshaft adjuster for a camshaft with an inner and an outer shaft minimizing possible space.
  • the invention is based on the general idea, at least part of the phase adjustment, in particular their switchable Arranging hydraulic valves substantially within an inner shaft of the existing of an inner and outer shaft camshaft.
  • the inner shaft is coaxially mounted in the outer shaft and rotatable relative thereto, wherein in addition to each other rotatable first and second cams are provided, of which the first cam fixed to the inner shaft and the second cam are fixedly connected to the outer shaft.
  • the camshaft according to the invention above-mentioned phase adjuster namely a first and a second phaser, wherein the first phaser a phase angle of the inner shaft and the second phaser a phase angle of the Outer shaft respectively relative to the drive, such as a crankshaft, adjusted.
  • the arrangement of belonging to the respective phase adjuster switchable hydraulic valve within the inner shaft allows a particularly space-saving and space-optimizing design. Of particular importance or advantage here is that the time required to control the hydraulic valves oil supply is also located within the inner shaft.
  • an oil supply which is already present for a bearing lubrication of the camshaft, so that no further hydraulic lines must be provided in the cylinder head.
  • the camshaft according to the invention can also be installed on conventional cylinder heads.
  • an actuating device for actuating or controlling the two hydraulic valves which has a first and a second electromagnet, of which the first solenoid actuates the first hydraulic valve and the second solenoid actuates the second hydraulic valve.
  • the electromagnets which are part of the actuating device, are preferably arranged stationary in or on the cylinder head and fixed in contrast to the rotating hydraulic valves. Electromagnets can be produced inexpensively today in almost any embodiment and also work extremely precise, whereby a reliable, accurate and at the same time inexpensive control of the hydraulic valves can be created.
  • the second electromagnet has a plunger for actuating the second hydraulic valve, which runs centrally through the first hydraulic valve.
  • This plunger which is arranged essentially coaxially with respect to the first hydraulic valve, makes it possible to control both hydraulic valves from a common side, whereby the tandem arrangement of the two hydraulic valves within the inner shaft becomes possible.
  • the axial channel within the first hydraulic valve required for penetration of the stoichel can thereby be provided without problems, since this area of the first hydraulic valve is not required for actuating the phasers in any way.
  • the existing in the warehouse anyway hydraulic channel serves to a bearing lubrication and can be used in addition to the supply of the two hydraulic valves. Since the hydraulic channel for lubricating the camshaft bearing is present in many conventional engines anyway, the camshaft according to the invention can be easily installed in conventional engines. At the same time, one channel allows a reduction of hydraulic lines to be arranged, whereby the complexity of the components, in particular the inner shaft and the bearing can be significantly reduced.

  • the camshaft 1 shown in Fig. 1 is designed as a so-called adjustable camshaft and therefore has mutually rotatable first and second cam, of which the first cam fixed to the inner shaft 3 and the second cam are fixedly connected to the outer shaft 2.
  • the first and second cams are not shown in Figs. 1 to 3.
  • a first phase adjuster 7 and a second phase adjuster 8 are arranged thereon, the first phase adjuster 7 having a phase angle of the inner shaft 3 and thus the first cam relative to a drive, for example a crankshaft, not shown , Adjusted, while the second phase adjuster 8 adjusts a phase angle of the outer shaft 2 and thus the second cam relative to the crankshaft.
  • the phase adjuster 7 and 8 thus change the phase position of the camshaft 1 and the inner shaft 3 and the outer shaft 2 relative to the crankshaft and thereby allow a reduction in fuel consumption or pollutant emission and an increase in power and torque.
  • first phaser 7 and the second phaser 8 each have a switchable hydraulic valve 9 and 10 (shown continuously in FIG. 1), which are both arranged inside the inner shaft 3. This allows a space-saving and thus space-minimizing arrangement of the phase adjusters 7, 8 associated hydraulic valves 9, 10 and one at the same time wear-resistant accommodation thereof within the inner shaft. 3
  • the two hydraulic valves 9, 10 are arranged in the axial direction of the shafts 2 and 3 adjacent to one another within the inner shaft 3.
  • This so-called tandem arrangement requires for the control of the two hydraulic valves 9 and 10, that for controlling in particular the second hydraulic valve 10, the first hydraulic valve 9 by a control, in particular a plunger 11 ', is penetrated.
  • an actuating device 12 is provided which has a first electromagnet 13 and a second electromagnet 14, of which the first electromagnet 13, the first hydraulic valve 9 and the second electromagnet 14 corresponding to the second hydraulic valve 10 is actuated.
  • both the first electromagnet 13 and the second electromagnet 14 in the region B that is arranged in a stationary area.
  • the actuating device 12 is arranged as a whole stationary on a cylinder head, not shown, while the hydraulic valves 9 and 10 are rotatably connected to the inner shaft 3.
  • the annular channel 16 thereby enables the camshaft 1 to rotate without any interruption of a hydraulic line 15 common to the oil supply.
  • the hydraulic channel 17 in the cylinder head side bearing element 5 simultaneously represents an oil supply for lubricating an annular gap between the two bearing elements 4 and 5 and is already present in conventional engines.
  • only one hydraulic line for supplying the two hydraulic valves 9 and 10 is required, whereby the complexity of the components, in particular of the bearing element 4 and the cylinder head side bearing element 5 can be significantly reduced.
  • the first hydraulic valve 9 is shown in FIGS. 2 and 3 of the necessary to actuate the second hydraulic valve 10 plunger 11 'penetrated centrally.
  • a pump 20 continuously pumps hydraulic fluid from a reservoir 21 through the respective lines 15 'and 15 "to the first hydraulic valve 9 and the second hydraulic valve 10.
  • the first hydraulic valve 9 is set so that both channels leading to the first phaser 7 23, 23 'are closed by corresponding projections 22, 22' on the slide 24 of the first hydraulic valve 9.
