Definitions
- the invention relates to a steering auxiliary drive for a steering mechanism, with a motor which has a drive shaft, and a belt drive with which the motor can drive the steering mechanism, the motor having a connecting element with an axis of rotation for mounting on the belt drive.
- Such a steering auxiliary drive is described for example in WO 01/15959 AI.
- This lerik mechanism is equipped with an axially displaceable rack and Lenld raft support from an electronically controlled electric motor, which acts on the rack via a belt drive.
- the belt drive has a housing to which the electric motor is flanged so that the drive shaft of the motor projects into the housing of the belt drive. There is a pulley at the end of the drive shaft, in which the belt of the belt drive is guided.
- the drive shaft of the motor is parallel and offset to its axis of rotation.
- the motor can thus be rotated about the axis of rotation of the connecting element during assembly, the drive shaft of the motor being pivoted and thus changing its distance from the steering mechanism.
- the belt tension can thus be varied in a simple manner and then fixed in the pivot position reached by fixing the motor.
- FIG. 1 shows a cross section through an auxiliary steering drive and part of a steering mechanism driven thereby.
- FIG. 2 shows a perspective view of a flange sleeve of the steering auxiliary drive from FIG. 1;
- FIG. 3 shows a view of the flange sleeve from FIG. 2 in the direction marked by III in FIG. 1;
- FIG. 4 shows a side view of part of the flange sleeve from FIG. 2;
- FIG. 5 shows a cross section through the flange sleeve from FIG. 2 along the line N in FIG. 1;
- FIG. 6 shows a cross section through the flange sleeve from FIG. 2 along the line N in FIG. 1 in the opposite direction;
- Fig. 7 is a view of the housing of the steering auxiliary drive from Fig. 1 in the in
- FIG. 8 shows a view of a housing part of the steering auxiliary drive from FIG. 1 in the direction marked by VIII in FIG. 1;
- FIG. 9 shows a cross section through the steering auxiliary drive from FIG. 1 in the direction marked by IX in FIG. 1.
- FIG. 1 shows a steering auxiliary drive 10 according to the invention with a motor 12 and a belt drive 14 in cross section.
- the auxiliary drive 10 serves to assist the steering force for a steering mechanism 16, which is only partially shown in FIG. 1, since the function of the steering mechanism itself is sufficiently known from the prior art.
- the motor 12 has an electric motor 26 with a drive shaft 18, which is housed in a motor housing 20.
- the drive shaft 18 protrudes from the motor housing 20 and is provided with a small pulley 22 at its free end.
- the motor housing 20 consists of a cylindrical hood 28 which is concentric with the drive shaft 18 and which is provided on the output side with a housing flange 24, and of a flange sleeve 30 which surrounds the end of the drive shaft 18 which projects on the output side.
- the flange sleeve 30 extends so far that it leaves the small pulley 22 free. Facing the hood 28, the flange sleeve 30 has a motor flange 32 with which it is fastened to the housing flange 24.
- the motor flange 32 comprises a cup-shaped motor mounting 34 formed in the flange sleeve 30, which can receive the electric motor 26 with a precise fit.
- the flange sleeve 30 is provided with a central, continuous bore 36 for the drive shaft 18.
- the drive shaft 18 is preferably mounted in the flange sleeve 30 by means of two shaft bearings 38, which are supported in the bore 36.
- the flange sleeve 30 is provided with an output flange 40 which defines a flange plane 42 perpendicular to the drive shaft 18.
- a rotationally symmetrical connecting element in the form of an annular collar 44 with an axis of rotation A extends perpendicularly from the flange plane 42.
- the collar 44 is arranged such that the drive shaft 18 of the motor 12 is parallel and offset from the axis of rotation A. That the collar 44 is eccentric to the drive shaft 18.
- the collar 44 can preferably be provided with a circumferential groove 45 for receiving a seal.
- arc-shaped elongated holes 46 are further formed, which are arranged in an arc around the axis of rotation A.
- the belt drive 14 has a belt housing 50, which one
- Drive belt 52 encloses and consists of a first housing shell 50a and a second housing shell 50b.
- the drive belt 52 wraps around on the one hand the small pulley 22 and on the other hand a large pulley 54.
- the large pulley 54 is connected to a ball nut 48 which runs on a spindle section 56 of the rack 58 of the steering mechanism 16, only a section of the rack 58 being shown in FIG. 1.
- the ball nut 48 converts the rotary movement transmitted by the motor 12 through the belt drive 14 into an axial displacement of the rack 58, as is sufficiently known from the prior art.
- the toothed rack 58 is surrounded on both sides of the belt housing 50 by protective sleeves 60, which are fastened to the belt housing 50, for example by means of screws 62.
- the belt housing 50 In the area of the small pulley 22, the belt housing 50, more precisely the second housing shell 50b, is provided with a drive opening 64 in which the collar 44 is received so as to be rotatable about the axis of rotation A.
- Drive opening 64 is advantageously cylindrical, its diameter being adapted so that the collar 44 can be rotated with a precise fit therein.
- the eccentric arrangement of the collar 44 with respect to the drive shaft 18 when the flange sleeve 30 is rotated in the drive opening 64, the axis of rotation A, the distance d between the drive shaft 18 and the axis of the toothed rack 58 changes of the motor 12 on the belt housing 50 by simply turning the flange sleeve 30, adjust the tension of the drive belt 52.
- the rotational position of the flange sleeve 30 can be fixed, for example by screwing it to the belt housing 50 with its driven flange 40.
- the arcuately shaped elongated holes 46 in the output flange 40 advantageously allow the flange sleeve 30 to be fixed in a wide, stepless adjustment range.
- a maintenance opening 66 is formed in the first housing shell 50a opposite the drive opening 64 of the second housing shell 50b, through which the free end of the drive shaft 18 is accessible.
- the maintenance opening 66 is closed with a cover cap 68.
- Connection element and the drive opening 64 conceivable that a rotation of the
- Allow motor 12 about the axis of rotation A For example, a polygonal drive opening in the belt housing or the design of the connecting element as arc segments would be conceivable.
- the invention thus makes it possible to change the belt tension in a simple manner when installing the auxiliary drive. For example,
- Tolerances of the drive belt can be compensated. Setting a defined belt tension can ensure maintenance-free and trouble-free operation of the auxiliary drive over the entire service life.
