Description

The invention relates to a gear arrangement for an actuator device of an adjustable roll stabilizer device for a motor vehicle, comprising a first gear device which forms a first gear stage, comprises several interacting, in particular intermeshing, gear elements, and at least one gear unit which forms a further gear stage and comprises several interacting, in particular intermeshing, gear elements further transmission device.

Such gear arrangements comprising several gear devices for actuator devices of adjustable roll stabilizer devices for motor vehicles are basically known from the prior art in a multitude of different embodiments, in particular as functional or structural components of motor vehicle-side drive trains.

With corresponding gear arrangements, friction effects, especially in the area of the interfaces between the gear units, sometimes lead to undesirable acoustic abnormalities, which can be expressed in the operation of corresponding gear arrangements, for example in a rattling or squeaking.

There is therefore a need for a further development of corresponding transmission arrangements with a view to improving the coefficient of friction and / or damping in the area of the interfaces between the corresponding transmission devices in order to avoid or at least reduce corresponding undesired acoustic abnormalities.

The invention is therefore based on the object of specifying a gear arrangement, which is improved in comparison, for an actuator device of an adjustable roll stabilizer device for a motor vehicle.

The object is achieved by a gear arrangement for an actuator device of an adjustable roll stabilizer device for a motor vehicle according to claim 1. The dependent claims relate to possible embodiments of the transmission arrangement.

A first aspect of the invention relates to a transmission arrangement for an actuator device of an, in particular electromechanically, adjustable roll stabilizer device for a motor vehicle. The transmission arrangement is therefore set up to form part of an actuator device for an, in particular electromechanical, adjustable roll stabilizer device for a motor vehicle.

The gear arrangement in all embodiments comprises a first gear stage forming a plurality of interacting, i. E. H. In particular, gear elements meshing with one another - corresponding gear elements are typically designed as gear wheels - comprehensive first gear device as well as at least one additional gear stage forming, several interacting, d. H. In particular, gear elements meshing with one another - corresponding gear elements are typically designed as gearwheels - comprehensive further gear device. The gear arrangement is thus designed in several stages in all embodiments.

In a specific exemplary embodiment, the gear arrangement can have a plurality of interacting, i.e. H. In particular, a first gear device which meshes with one another and comprises gear elements, a plurality of interacting gear units forming a second gear stage, d. H. in particular intermeshing, gear elements comprising second gear device and a third gear stage forming a plurality of interacting, d. H. in particular, intermeshing third gear means comprising gear elements. The gear arrangement can thus be designed in three stages.

In order to improve the coefficient of friction in the area of the interfaces between the gear units of the gear arrangement, i.e. in particular between axially (immediately) adjacent gear units arranged axially adjacent, and thus to avoid or at least reduce corresponding undesired acoustic abnormalities, the gear arrangement is between a gear element of the first gear device - this is, as mentioned, typically a gear wheel of the first gear device - and a gear element of the at least one further gear device - this is, as mentioned, typically a gear wheel of the at least one further gear device - at least a roller bearing comprising a plurality of roller bodies is arranged or configured or configured. The rolling properties of the rolling bearing, ie the rolling properties of the rolling elements of the rolling bearing, reduce the friction in the area of the interfaces between the respective gear units of the gear arrangement, ie in particular between axially (immediately) adjacent gear units arranged axially adjacent, and thus lead to an avoidance or Reducing unwanted acoustic Abnormalities in the area of the interfaces between the respective gear units of the gear arrangement.

The at least one roller bearing is typically arranged or designed in such a way that its central axis is aligned with the central axis of the gear arrangement. The at least one roller bearing is therefore typically arranged or designed coaxially with the gear arrangement.

In exemplary embodiments, the gear arrangement can have a plurality of corresponding roller bearings. For all embodiments of the transmission arrangement with a plurality of roller bearings, it applies that typically only one (single) roller bearing is arranged or formed between the respective transmission elements of the respective transmission devices.

Overall, there is an improved transmission arrangement for an actuator device of an adjustable roll stabilizer device for a motor vehicle.

In addition to its special rolling bearing properties, a corresponding rolling bearing can also be distinguished by special damping properties. A corresponding roller bearing can therefore also be set up to reduce the damping in the area of the interfaces between the respective transmission devices of the transmission arrangement, i. H. in particular between axially (directly) adjacent gear elements of the gear arrangement and thus also contributes to the avoidance or reduction of undesirable acoustic abnormalities in the area of the interfaces between the respective gear devices of the gear arrangement.

The first gear device of the gear arrangement can be designed as a first planetary gear comprising a sun gear. As an alternative or in addition, the at least one further gear device of the gear arrangement can be designed as a planetary gear comprising a sun gear.

The sun gear and the planet carrier of a respective planetary gear are typically mounted rotatably about a common axis of rotation. A corresponding axis of rotation is typically the central axis of the gear arrangement.

If the first gear device is designed as a first planetary gear comprising a sun gear and the at least one further or second gear device is designed as a planetary gear comprising a sun gear, the at least one or at least one roller bearing between the sun gear of the first planetary gear and the sun gear can further or second planetary gear be arranged or formed. This is a particularly expedient arrangement or design of a respective roller bearing in order to improve the coefficient of friction in the area of the interfaces between the respective gear units of the gear arrangement. Equally, this arrangement of a respective roller bearing can improve the damping between the respective transmission devices of the transmission arrangement.

In principle, independently of the specific design of the transmission devices, the at least roller bearing can be arranged or designed with a clearance fit between the respective transmission element of the first transmission device and the respective transmission element of the at least one further transmission device. The at least one roller bearing can therefore be mounted in a floating manner. The clearance fit, d.

Mixed forms are of course also possible; consequently, at least one first roller bearing with a clearance fit and at least one further roller bearing with a clamping or press fit can be arranged or formed on or in a transmission element of a transmission device.

At least one, in particular pocket-like or pocket-shaped, receiving or running area for the rolling elements of the at least one rolling bearing can be arranged or formed in at least one transmission element of the first transmission device and / or the at least one further transmission device.

In this way, a particularly compact design of the roller bearing can be implemented.

The respective second ring sections of the first ring can overlap the respective second ring sections of the second ring axially with respect to the central axis of the roller bearing. In this way, the aforementioned particularly compact design of the roller bearing can be implemented. For all embodiments or variants of a corresponding roller bearing, it typically applies that this is set up to absorb forces acting axially with respect to the central axis of the roller bearing or the central axis of the gear arrangement.

B. have a configuration with a roller bearing between a transmission element of a first transmission device and a transmission element of a second transmission device and a corresponding sliding body between the transmission element of the second transmission device and a transmission element of a third transmission device. A corresponding roller bearing can therefore, for example, be arranged or formed between an output side of the first transmission device and the input side of the second transmission device, and a corresponding sliding body can therefore be arranged or formed, for example, between an output side of the second transmission device and the input side of the third transmission device. Of course, a configuration reversed to this is also possible.

2 shows a schematic diagram of a gear arrangement 8th according to an embodiment. 2 shows only part of the gear arrangement 8th which is essential for the explanation of the invention described herein.

As in connection with the in 1 Mentioned embodiment shown, is the gear arrangement 8th set up, part of an actuator device 2 for an adjustable roll stabilizer device, in particular an electromechanical one 1 form for a motor vehicle.

The gear arrangement 8th includes in the in the 2 - 5 A plurality of interacting, ie in particular meshing, gear elements - corresponding gear elements are designed as gear wheels - comprising a first gear device (first planetary gear 8.1 ), a second gear stage forming a plurality of interacting, ie in particular intermeshing, gear elements - corresponding gear elements are designed as gear wheels - comprehensive second gear device (second planetary gear 8.2 ) and a third gear stage forming a plurality of interacting, ie in particular meshing, gear elements - corresponding gear elements are designed as gear wheels - comprehensive third gear device (third planetary gear 8.3 ). The gear arrangement 8th is in the in the 2 - 5 Embodiments shown are thus designed in three stages.

Based on 2 it can be seen that in a sun gear 8.1.1 - 8.3.1 a planetary gear 8.1 - 8.3 , ie specifically z. B. in the sun gear 8.2.1 of the second planetary gear 8.2 - a, in particular pocket-like or pocket-shaped, receiving or running area 10 for the rolling elements 9.1 of the rolling bearing 9 can be arranged or formed. A corresponding recording or running area 10 can concretely by one, z. B. recess-like or -shaped, recess in the respective sun gear 8.1.1 - 8.3.1 be trained. The dimensions of the respective recording or walking area 10 are typically with a view to a desired mounting of the rolling bearing 9 to the dimensions of the respective rolling bearing 9 customized. In all cases, a corresponding recording or running area enables 10 the explained desired functionality of the rolling bearing 9 in the gear arrangement 8th .
