Definitions
- the present invention relates to an adjusting shaft of a variable-stroke valve drive an internal combustion engine according to the preamble of claim 1.
- the present invention now provides an adjusting shaft of a variable-stroke valve drive an internal combustion engine, wherein the adjusting shaft is an elongated Has shaft body, which is in operative connection with a pivot lever Eccentric cam and a drive component for the rotary drive of the adjusting shaft has, wherein according to the invention it is provided that the shaft body, the eccentric cam and the drive member are manufactured separately from each other and the eccentric cams and the drive member for forming the adjusting shaft on the shaft body arranged according to their respective production.
- the shaft body of an at least partially pipe-shaped hollow body is formed, compared with the known wave a significant cost advantage in the production of adjusting shaft according to the invention provides.
- a solid shaft are used in the form For example, one already finished in the field of bearings Wave.
- the drive component is generally a displacement an output component of a drive in a rotational movement of the adjusting converting Component.
- As drive for example, an electric motor or a hydraulic Drive are used, whose output component is displaced.
- the output member is engaged with the drive member on the shaft body and can thus rotate the adjusting shaft.
- This may be the case with the drive component for example, a spur gear of a spur gear or a Schneckenradlace a worm gear or a rack and pinion or a Crankshaft act.
- the eccentric cam and / or the drive component in the Shape for example, a helical gear or worm wheel by means of a punching operation are manufactured and after their production on the hollow basic body be put on.
- the adjustment shaft provided according to the invention has to their bearings on shaft bearings, those of rolling bearings or plain bearings or both Bearing types are formed, which arranged by means of on the base body Eccentric cam supporting spacers are positioned on the shaft body can, so that also a significantly cheaper positioning of the Bearing on the adjusting shaft is possible.
- the spacers force fit for example in the form of a press fit to the shaft body.
- the drive component provided for the rotary drive of the known adjusting shaft is for manufacturing reasons in this known adjusting largely arranged in the region of the axial longitudinal center and therefore leads to a problem the so-called packaging, as in this area often cylinder head bolts are provided on the internal combustion engine and thus the problem of a restriction the clearance of the cylinder head bolts consists.
- the eccentric cam and / or the Drive component on the shaft body by means of a non-rotatable shaft / hub connection be determined, provided for this purpose, for example, a knurling can be.
- the adjusting shaft according to the invention can over the already described above Drive component by means of a standing in operative connection electric motor be driven for pivoting or pivoting movement, wherein the drive due to the respective end positions of the eccentric cam relative to the above-described Transmission mechanism has to be done so that a rotation of the Adjusting be avoided over a predetermined rotation angle range addition got to.
- the drive component formed with at least one rotation angle limit stop is, so that the drive component in addition to the function of the drive of the adjusting also performs the function of limiting the rotation angle range of the adjusting.
- the invention is also characterized by the fact that the shaft body and / or the eccentric cam and / or the drive component of different Materials, according to the respective requirement profiles, manufactured can not be the case that the entire wave from one, the most heavily loaded component selected according to uniform Material must be made.
- adjusting shaft it is one for a four-cylinder inline engine with each two intake valves provided adjusting shaft.
- the adjusting shaft 1 has an elongated Basic body 2, of a simple and inexpensive to produce is hollow inside and thus tubular piece-shaped continuous tubular body is formed, at the then after the production of the other parts of the adjusting this subsequently can be put on. It is also instead of the tube body shown possible to use a solid shaft.
- the adjusting shaft according to the illustrated embodiment a total of eight eccentric cam 3, the For example, can be manufactured as cost-effectively produced stampings and between each intended for storage of the adjusting Needle roller bearings 4 are arranged.
- the adjusting shaft 1 of the invention has a drive member 5, the on a substantially front end portion of the adjusting shaft 1 is arranged and thus the above-described problem of clearance of the cylinder head bolts solves.
- the drive component is a, a pitch circle from about 180 ° enclosing component with an external toothing for engagement in the output worm of an electric motor, not shown, with which the Adjusting shaft 1 can be rotated so that the eccentric cam. 3 act on the transmission mechanism, not shown, so that a Rotation of the intake camshaft to open the intake valves of the internal combustion engine with variable stroke leads.
- To a rotation of the adjusting shaft. 1 To avoid beyond the constructive angle of rotation range, has the drive member 5 two rotation angle limiting stops 6, in a not shown in detail component can intervene to limit the rotation angle.
- the invention is characterized in that the adjusting shaft according to the invention can be made much cheaper than the one from a one-piece forged component manufactured known adjusting shaft. Furthermore can form the individual components of the adjusting shaft according to the invention Components made of different application-specific ones There are therefore materials that are optimized for the respective component-specific load can be. It is particularly possible, the tubular piece-shaped shaft body 2 of a simple material to form while the mechanical higher loaded eccentric cam 3 from a corresponding to monten Material are manufactured. It is not in the adjusting shaft according to the invention more necessary to subject them to a heat treatment after their manufacture, so that the problem of any thermal distortion of the elongated Wave is avoided.
- the adjusting shaft can due to the closed bearings 4 in contrast to the split bearings used in the known shaft be stored precisely and in addition, the one have undivided Bearing outer bearing bearing increased load capacity.
- the shaft according to the invention has the advantage of being complete can be finished and pre-assembled and so on the assembly line in the cylinder head of the internal combustion engine can be used without the Band further steps are required.
