Definitions

  • the invention relates to a device for releasably connecting and adjusting the camshaft and the crankshaft of an internal combustion engine, in particular according to the preamble of claim 1.
  • variable displacement motor systems can be the variable motor and / or its Control fail and thereby prevent the achievement of the base position.
  • DE 41 10 195 A1 discloses a device for releasably connecting and adjusting describes the camshafts and the crankshaft of an internal combustion engine, with a trained as a three-shaft gear adjustment, the one crankshaft-connected drive shaft, a camshaft-connected Output shaft and connected to an electric variable motor Has adjusting shaft, wherein between the input and output shaft at a standstill Adjusting a stationary gear ratio io is present, the height of the Transmission type (negative or positive gear) and the adjustment direction of the camshafts determined who have a basic or emergency position.
  • This adjustment is a smooth and accurate adjustment the camshaft position sought. So in case of failure of the variable displacement engine system the function of the internal combustion engine maintained at least makeshift can be, a limitation of the adjustment is provided. A note upon reaching the base or emergency position in such a case is missing however.
  • the invention is therefore based on the object, an electric camshaft adjuster to create, in which the camshaft even in case of failure of Adjusting motor and / or the same control in its base position adjustable is.
  • the object is solved by the features of patent claim 1.
  • the camshaft After deceleration or setting of the adjusting be adjusted by turning the drive shaft in the low idle of the engine or - if it was strangled - when restarting the same, even with failed Verstellmotor system, the camshaft in its basic or emergency position. In this position, the vehicle can be started and operated with certain restrictions, so that a workshop can be achieved.
  • Prerequisite is a suitable stationary gear ratio i 0 , by the desired transmission type (plus or minus) and the adjustment (late or early) is determined.
  • the output shaft rotates faster than the drive shaft, that is, in the clockwise direction and thus in the direction of advance.
  • the adjusting motor with a permanent magnet rotor has a passive self-holding moment, which from a middle position in both directions of rotation rise to a maximum and then fall again.
  • the increased by the converted friction torque of the variable transmission Self-holding torque of the adjusting motor must be only 60% - 100% of the converted maximum dynamic camshaft torque retroactively acting on the adjusting shaft because the energy content of the tips of the camshaft torque is low and the necessary holding torque more through the mean camshaft torque is determined.
  • the use of a permanent magnet rotor has the advantage over a permanent magnet stator that the current only has to be conducted into the cylinder-head-fixed stator.
  • the adjustment speed of the camshaft is preferably between 30 ° and 60 ° cam angle per second due to the selected stationary gear ratio i 0 with stationary adjusting and low idle speed of the engine. It is irrelevant whether the adjusting motor adjusted when returning the camshaft in its base position in one or two directions of rotation.
  • eccentric or wave gear Pulsitive gear
  • wobble or double planetary gear minus or plus gearbox
  • the adjusting motors are as usual brushless Permanent magnet rotor motors or as brush-mounted external excitation DC motors trained.
  • Figures 1 and 2 are adjusting 1, 1 'with electric adjusting motors 2, 2 'shown, for adjusting the rotational angle position between the not shown crankshaft and the camshaft 3, 3 'of an internal combustion engine serve.
  • the adjusting 1, 1 ' is designed as a three-shaft gear, with a drive shaft 4, 4 ', an output shaft 5, 5' and an adjusting shaft 6, 6 '.
  • the drive shaft 4, 4 ' is connected to a drive wheel 7, 7' and via this means a gear, not shown, or toothed belt or a toothed chain firmly connected to the crankshaft.
  • the output shaft 5, 5 ' is connected to the camshaft 3, 3' and the adjusting shaft 6, 6 'with the rotor 8, 8' of the adjusting motor 2, 2 'in a fixed connection.
  • the stator 9 of the adjusting motor 2 is fixedly connected to the cylinder head 10 and stands still, the stator 9 'of the adjusting motor 2' is connected to the drive wheel 7 ' firmly connected and rotated as the adjusting 1 with half crankshaft speed.
  • the camshaft 3, 3 ' has a base or emergency running position, the for a safe start and limited operation must be achieved. This succeeds intact adjustment motor 2, 2 'even after a stalling of the engine without difficulty, since the adjusting motor 2, 2 'the camshaft 3, 3 'with the internal combustion engine or during the restart adjusted to the base position. But it also has to be with failed adjustment motor 2, 2 'a restart may be possible to at least one workshop to reach.
  • the adjusting gears 1, 1 'and their stationary gear ratio io are designed to that merely by setting the adjusting shafts 6, 6 ', the camshafts 3, 3 'get into their base position when starting and the internal combustion engine so that it remains bootable.
  • the setting of the adjusting 6 can by a de-energized variable motor 2 with permanent magnet rotor 8 or permanent magnet stator 9 done.
  • the adjusting motor 2 has a self-holding torque that of a central position off in both directions up to a maximum and after falls again.
  • the self-holding torque is the maximum torque, with which one can statically load a non-energized variable motor, without one to cause nonuniform but continuous rotation.
  • the self-holding torque is due to the converted friction torque of the variable speed 1 reinforced to the cogging torque, which is between 60% and 100% of the converted maximum, dynamic camshaft torque at low Idle speed of the engine should be.
  • the camshaft 3 After a stalling of the internal combustion engine or after failure of the adjustment motor 2, the camshaft 3 may be in an undefined position. By setting or hard braking the adjusting 6, the camshaft 3 on the subsequent start by that caused by the starter Rotary movement of the drive shaft 4 adjusted in its base position, so that a start is possible.
  • stator 9 'of the adjusting motor 2' (see Figure 2) with its rotor 8 ' mitrotiert is a setting of the adjusting shaft 6 'by a between stator 9' and rotor 8 'effective self-holding torque not possible.
  • the mechanical serves or electrical stalling of the adjusting shafts 6, 6 'also for thermal relief of the adjusting motors 2, 2 '.
