- the arms have in the region of the articulation at the middle part depending on a bending joint.
- the central middle part is connected via a respective pair of arms with the transmission input shaft and the externally toothed transmission element.
- An arm between the central part and transmission input shaft or central part and external gear element consists of two mutually parallel webs.
- the torque support consists of a plate, preferably made of spring steel, which has cut out the serving for elastic coupling elements.
- the Versteilantrieb is designed as a camshaft adjuster an internal combustion engine, wherein the transmission input shaft is driven by the crankshaft of the internal combustion engine Nockenwellenantriebsrad, the adjusting shaft is driven by a preferably electric drive and the ring gear is coupled to the camshaft.
- the adjusting drive according to the invention thus consists of a three-shaft gear, with a transmission input shaft, an adjusting shaft, which drives an externally toothed gear element, a gear eccentric and a transmission output shaft, which is coupled to a ring gear, which is driven by the eccentric of the adjusting externally toothed transmission element , the gear interacts with a torque support between the transmission input shaft and the externally toothed transmission element, which has elastic coupling elements in the radial direction.
- the coupling elements act in the direction of rotation rigid, rigid, allow by the elasticity in the radial direction, the free movement of the running gear on the eccentric and its coupling to the transmission input shaft.
- the torque transmission, torque support between the externally toothed transmission element and the Nockenwellenantriebsrad is realized by a special component (coupling element).
- the component has elastic as well as very rigid areas, so that it can be moved between two off-axis shafts (externally toothed gear element, eccentrically running and a centrically rotated shaft). henden wheel - the camshaft drive) on the one hand torque (torsionally stiff as possible) can transmit, but does not affect the radial misalignment of these two parts.
- the radial offset between these parts is given by the eccentricity value of the eccentric shaft (carries and drives the transmission element).
- the guide element consists according to a preferred embodiment of the invention, at least two types, pairs of arms and a stiff middle part.
- the arms are ideally parallel to each other.
- the arms are also ideally arranged at right angles to the other arms. All these arms contribute to the transmission of torque between the
- a pair of arms are connected to the camshaft drive wheel via pins and leave with their correspondingly elastic pivot bearing with very little
- the flexurally elastic pivot bearing of a pair of arms allow with very little effort a shift of the externally toothed transmission element in the vertical direction to the other pair of arms relative to the center part.
- this flexible guide element keeps the externally toothed transmission element radially soft or does not radially lead with respect to the Nockenwellenantriebsrad, but transmits torque between these two parts.
- Figure 1 shows a perspective view of an eccentric as adjusting for a camshaft adjuster.
- a base plate GP is coupled to the camshaft (not shown) - directly connected to it.
- a ring gear HR with internal teeth is firmly connected to the base GP. This can be a one-piece molding - or two parts are pressed, welded.
- adjusting shaft VW On an eccentric outside of its axis of rotation formed adjusting shaft VW, which is coupled to an electric Versteilantrieb sitting on an eccentric bearing EL with a bearing inner ring LI the outer toothing having GE gear element.
- the O-rings OR (or spring elements) are assigned to the bearing inner ring LI and press the eccentric bearing EL in the direction of more eccentricity (backlash-free).
- the bearing inner ring LI is axially fixed together with the O-rings OR on the adjusting shaft VW.
- the adjusting shaft VW is mounted on a central eccentric ZEL on a central pin ZZ of the base plate GP.
- the camshaft drive wheel NAR is mounted concentrically but rotatably relative to the base plate GP or ring gear HR. As FIG. 5 shows in particular, the camshaft drive wheel is seated on the ring gear HR, is rotatable relative thereto, and is axially fixed by means of the circlip SNW.
- a flexible guide element FE is used for torque transmission
- this element FE does not cause any guidance of the externally toothed transmission element GE - this moves in accordance with the driving eccentric of the adjusting shaft VW.
- the flexible guide element FE is connected by means of pins ST with the Nockenwellenantriebsrad NAR coupled.
- the pins ST sit in corresponding pin Stegen, shots AST of the camshaft drive wheel NAR.
- the eccentrically mounted to the axis of the transmission gear member GE has at two opposite end faces each have an outer toothed segment ASG, in which the external toothing across the width - and the engagement in the internal toothing of the ring gear HR corresponding width - of the transmission element GE is increased.
- These outer toothed segments ASG serve to receive, articulation of the flexible guide element FE.
- FIGS. 3 and 4 show, side by side, the view of the adjusting mechanism similar to that in FIG. 2 - once with and once without the flexible guiding element FE.
