Definitions
- the invention relates to an adjusting device for a device for relative Change of rotational position of a shaft to a drive wheel, in particular a camshaft an internal combustion engine, according to the preamble of claim 1.
- An adjusting device is known (WO 95/31633) with which the rotational position of the Camshaft of an internal combustion engine can be changed.
- the camshaft carries rotatably an inner wheel, which has radial webs, the assigned cells one Cell wheel divided into two opposing pressure chambers. This The cellular wheel is driven by the crankshaft via a chain or belt drive Internal combustion engine driven.
- the pressurization of the respective pressure rooms takes place via a control valve designed as a 4/3-way valve, via which the Pressure rooms depending on the desired change in rotational position with a Pressure medium pump or a pressure medium tank are connected. This leads to this Control valve one pressure line each to all pressure chambers acting in the same direction.
- each of these pressure lines is also hydraulically unlockable Check valve arranged, the blocking effect of each pressure in the other Pressure line can be canceled.
- These check valves can be in the neutral position of the Control valve if the leakage losses are neglected, a hydraulic clamping of the two components rotatable relative to each other can be achieved.
- Such a facility is however relatively expensive.
- it can during the adjustment process due to the almost unthrottled connection of one pressure chamber group to the Pressure medium tank to unwanted position deviations and inaccurate or fluctuating Adjustment processes come.
- US-A 4,858,572 is also a device for changing the rotational position known in which an inner part is rotatably connected to the end of the camshaft and has on the outside a plurality of radial slots distributed over the circumference, in which wing elements are guided radially.
- This inner part is made by one Surround cell wheel, which has several hydraulically actuated cells, which by the wings are divided into two pressure chambers acting against each other. By pressurizing these pressure spaces, depending on the Pressure difference rotates the cellular wheel relative to the inner part and thus to the camshaft become.
- two radial bores are defined in the cellular wheel Angular positions each guided a hydraulically loaded piston, which in the assigned end position of the device in a radial recess of the inner part can be inserted.
- These pistons are directed towards by compression spring elements Inner part acted upon and are in the opposite direction by hydraulic action on the Bores in the inner ring can be moved.
- This spring-loaded piston Device can be locked in one of its two end positions, as long as the pressure to Loading of the pressure rooms did not reach a defined level. Only when reached a certain pressure level, the pistons are against the action of the compression springs pushed back and allow rotation of the inner part relative to the cellular wheel.
- Such a device should include rattling noises when starting the Internal combustion engine can be avoided by changing moment loads can occur during startup and operation of the internal combustion engine.
- the invention is based on the object, the generic Device for changing the relative rotational position of a shaft to the drive wheel improve that this is simple and inexpensive and a fluctuation-free change of the rotation position enables. It should focus on the The use of several complex and expensive control valves can be dispensed with.
- the A simple-acting hydraulic locking device can be set up.
- a damping or throttling acting on the entire adjustment process Drainage side is reached when the control cross section via the tank connection to a Pressure medium tank is always smaller than that during the adjustment process Opening cross-section of the connection of the pressure connection to the pressure medium pump.
- a particularly advantageous and inexpensive training of the device for the relative Rotation change occurs when both the inflow control and the Sequence control for the assigned direction of rotation via a common valve member of the Control valve is controlled.
- Such a device for the relative change in rotational position is simplified once again or less expensive if that for both directions of the change in rotational position common control valve or the common valve member can be used.
- the control valve can in a particularly advantageous manner as a 4/3-way valve be designed, which for the inlet and outlet control for both directions of rotation acting valve member is designed as a valve slide.
- 1 denotes the camshaft of an internal combustion engine on which At the end, a device for, for example, known from DE 39 37 644 A1 hydraulic rotation angle adjustment of the camshaft relative to its drive wheel or is arranged to the crankshaft.
- This adjustment device 2 has a rotationally fixed with the Camshaft connected inner part 3, which is provided with radial webs 4. This divide the cells of a cellular wheel 5, delimited by radial webs 6, into each two opposing pressure rooms.
- the cellular wheel 5 is both the drive wheel and for example with a chain drive or belt drive with the crankshaft Internal combustion engine connected.
- the inner part 3 connected to the camshaft 1 can have pressure spaces relative to the cellular wheel 5 are rotated so that the phase position of the gas exchange valves are actuated Change cams.
- the hydraulic control of the pressure chambers takes place via two in the camshaft Separately formed pressure channels 7 and 8, the two in one Camshaft bearings 9 formed annular grooves 9 and 10 each with a control line 11 or 12 are connected.
- the two control lines 11 and 12 are with one Control valve 13 connected, in this embodiment as a 4/3-way valve is trained.
- the connection of the control valve 13 to the control line 11 is A designated, the connection to the control line 12 with B.
- the control valve 13 has a Pressure port P and a return port T on.
- the pressure port P is over a Pressure line 14 and a check valve 15 with the serving as a pressure medium source Lubricant pump 16 connected to the internal combustion engine. This in turn is over a suction line with the oil storage tank 17 or the oil pan of the internal combustion engine connected.
- the return port T of the control valve 13 is also with this Oil storage tank 17 connected.
- This valve member 25 has two spaced, sealing in the Valve bore 19 guided piston sections 26 and 27, which have a piston section 28 smaller diameter are interconnected.
- annular space 29 Through the two Piston sections 26 and 27 between the piston section 25 and the Wall of the valve bore 19 formed annular space 29 completed.
- the length of the Piston section 25 and the length of the piston section 26 and 27 are so on the Width and spacing of the ring grooves 20 to 24 matched that in the neutral position II of the control valve 13, the annular grooves 21 and 23 through the piston portion 26 and 27th are tightly closed.
- the distance between the two facing ends of the Piston sections 26 and 27 is necessary for a secure seal Dimension smaller than the distance between the mutually facing sides of the annular grooves 21 and 23.
- the length of the piston sections 26 and 27 is chosen so that the coverage of the Ring grooves 21 and 23 clearly on the end facing away from the pressure port P. is bigger.
- the valve member 25 from the neutral position shown in Fig. 2 II, for example, shifted to the right in switching position I, the pressure connection P facing region of the annular groove 23 no longer covered by the piston section 27 or released.
- the larger one Coverage of the annular groove 21 is still completely covered by the piston section 26.
- the one assigned to the pressure connection B can thus be used Pressure chamber are applied without the opposite, the pressure connection A assigned pressure chamber is relieved.
- the annular groove 21 is on the side facing the annular groove 20 no longer covered by the piston section 26 or released by this, so that the Connection A to T is opened.
- the dimensions and spacing of the ring grooves are matched to the dimension of the valve member so that the opening cross section - when moving the valve member to the right - always larger than at the annular groove 23 the annular groove 21 is (drain edge control).
- the valve member 25 is made in an analogous manner the neutral position II moved to the left in the switching position III, the Pressure port P facing side of the annular groove 21 no longer from the piston section 26 covered.
- the piston section 27 on the other hand seals due to the larger Cover the annular groove 23 still completely.
