Definitions
- the invention relates to a recirculating ball gear, in particular for a steering system of a motor vehicle, with a nut mounted in a housing by means of a bearing, wherein at least one spring element is arranged on each end face of the bearing between the bearing and the housing.
- the generic recirculating ball gear can be exposed during operation in the axial direction of shocks, which can lead to damage of the ball gear and disturbing rattling noise due to a game in the camp over time.
- the invention therefore has the object to improve a ball screw transmission of the type mentioned in that acting in the axial direction shock loads can be attenuated.
- the invention solves this problem with a generic recirculating ball bearing, in which according to the invention, the spring elements are operated in the progressive range of a characteristic.
- the spring elements are operated in the progressive range of a characteristic.
- the characteristic curve of the spring elements can have both a degressive and / or a linear component, which, however, does not come into play during operation.
- the characteristics of the spring elements can also be purely progressive.
- the spring elements may have a certain preload, wherein a preload and a biasing force are in the range of a small slope of the progressive portion of the characteristic.
- the rattling noises that result from the game in the camp can be damped.
- the clearance is generally relatively small compared with the suspension travel required for damping, the preload and preload force may conveniently be close to the transition past which the characteristic increases steeply.
- the spring elements can be connected in parallel and / or in series.
- the spring elements may be a corrugated spring and / or a plate spring, since with it the respective desired progressive region of the characteristic curve can be realized cost-effectively.
- this range of the characteristic curve can also be represented with discs made of elastomers.
- the bearing may be an outer ring exhibiting rolling bearing, wherein the spring elements abut the outer ring.
- a stop element may be provided between the spring elements and the housing. In this way, the spring travel of the spring elements can be precisely defined.
- an inner ring of the bearing can sit on the nut and the inner ring can be fastened to the nut by means of a fastening ring.
- the attachment ring may be a snap ring.
- the spring elements may rest on the inner ring of the rolling bearing, wherein the outer ring is fixed in this case on the housing so that it can not be moved axially.
- the invention also relates to a steering for a motor vehicle, in particular a steering with electric power assistance, which according to the invention comprises the ball screw transmission according to one of claims 1 to 7.
- Fig. 1 is a sectional view through a recirculating ball gear
- Fig. 2 is a sectional view through a bearing
- Fig. 3 is a sectional view through a second embodiment of
- Fig. 1 shows a ball screw 10 with a threaded spindle 1 1 and a mother arranged thereon 12 of a steering not shown here of a motor vehicle.
- a roller bearing 13 which is surrounded by a housing 14.
- balls 1 5 are arranged.
- the threaded spindle 1 1 are moved in the axial direction to the left and to the right.
- Fig. 2 shows a bearing 20 which sits on a nut 21.
- the bearing has an outer ring 22 and an inner ring 23.
- a spring element 24 is disposed on the end faces of the bearing 20, wherein the spring element 24 in the illustrated case is a corrugated spring.
- the spring elements 24 dampen impact loads that act on the bearing 20 in the axial direction. Such shock loads occur in the operation of the steering, when the mother 21st starts to rotate or the direction of rotation is changed. Due to an unavoidable clearance in the bearing 20, audible rattling noises would result if the spring elements 24 did not damp the shock loads.
- the stop elements 26 define the spring travel of the spring elements 24.
- the inner ring 23 is arranged with a fixing ring 25 on the nut 21 in a form-fitting manner. Thus, axially acting movements and loads can be transmitted from the nut 21 to the bearing 20.
- Fig. 3 shows a bearing 30 in which an outer ring 31 is fitted in a housing 32, so that the bearing 30 is fixed in the axial direction.
- An inner ring 33 rests on the nut 21st Between the mounting rings 25 and the inner ring 33 designed as a wave spring spring element 24 is arranged.
- the spring elements thus dampen the impact loads that act on the bearing 30 in the axial direction. Further, rattling noises due to the game are reduced in the camp 30 so that they are not audible.
- the characteristic curve has an exclusively progressive course. In order to damp the jerky loads particularly reliably, the flat course of the characteristic curve is mainly relevant. The increasing region of the characteristic prevents the spring elements 24 from being compressed to such an extent that impact-like loads are exerted on the housing 14 and 32. In order to avoid the play in the bearing 20 and the associated rattling noises, the spring elements 24 can be biased, wherein a Vorspannweg and a biasing force are in the range of the lower slope of the curve. Since the clearance in the bearing 20 is relatively small compared to the spring travel required for damping, the preload and the preload force may be close to the transition behind which the characteristic increases steeply. The biasing path may therefore be in the region of the arrow in FIG. 3, for example. LIST OF REFERENCE NUMBERS
