Description

[0001] The present disclosure relates to a steering sensor assembly and a steering sensor system. In particular, the steering sensor assembly can be provided for the steering sensor system. The subject matter of the present disclosure can be used for vehicles, in particular for two-track motor vehicles.

[0002] Steering sensors are typically used in motor vehicles to determine the angle between a steering knuckle and a stationary part of the vehicle, such as an axle or axle housing. The sensor is typically mounted on a steering-side end of the axle, coaxial with the steering axis. Current technology offers two main sensor mounting locations: one is typically a Hall-effect sensor mounted on the kingpin and extending along the steering axis. The other is the sensor mounted on the rotating steering knuckle, and the other, such as a magnet, is mounted on the stationary axle. This solution has the disadvantage that a sensor cable required for connecting the sensor can rotate freely with the steering knuckle against the axle and is thus subject to damage and excessive wear, which is problematic due to potential signal loss.Second, the sensor can be installed in a special housing in the stationary axle, with the sensor counterpart connected to the top of the rotating knuckle. For protection, the cables are then placed in a special channel inside the axle to prevent wear and damage. However, this requires more complex casting, assembly, and / or higher part costs.

[0003] It is therefore an object of this disclosure to provide an alternative and improved steering sensor arrangement and an alternative and improved steering sensor system. The improvement is based in particular on simplifying assembly and installation and reducing wear.

[0004] This object is achieved by a steering sensor arrangement and a steering sensor system according to the independent claims. Particular embodiments and further developments are the subject of the dependent claims and the following description.

[0005] A steering sensor assembly for detecting a steering angle between a stationary component and a rotatable component is proposed. The steering sensor assembly comprises a sensor that is at least partially fixed with respect to the steering axis and a sensor counterpart that is movable about the steering axis. The sensor and the sensor counterpart are arranged at a distance from the steering axis.

[0006] The sensor arrangement in which the sensor and the sensor counterpart are arranged off-center to the steering axis can simplify installation and / or reduce excessive wear, particularly since the sensor arrangement can be arranged in a typically less functional area of ​​the stationary and rotating component.

[0007] In general, the steering axis corresponds to the axis of rotation about which the rotating component is rotatable about the stationary component. A spaced arrangement from the steering axis refers to a radial distance measured orthogonal to the steering axis. The corresponding radial distance can include values ​​of at least 1 cm, 5 cm or 10 cm and at most 5 cm, 10 cm or 30 cm. The sensor and the sensor counterpart can be arranged at the same radial distance from the steering axis. Alternatively, the sensor and the sensor counterpart can be arranged at different radial distances. However, they can be arranged together in a plane, in particular in a plane orthogonal to the steering axis.

[0008] The sensor and / or the sensor counterpart can extend at least partially in the circumferential direction around the steering axis. Alternatively or additionally, the sensor counterpart can be movable in the circumferential direction around the steering axis. For example, the circumferential movement of the sensor counterpart can be coupled to the rotation of the rotatable component relative to the stationary component about the steering axis. The resulting range of movement and / or extension, also referred to as the detection range, can cover a limited area, in particular a center angle of no more than 225°, 180°, or 120° and / or no less than 30°, 60°, or 90°. The center angle of the detection range can correspond to the maximum steering angle of the rotatable component relative to the stationary component.In other words, instead of a completely circular shape, the sensor arrangement can also have a partially circular shape, the angular extent of which can cover an entire steering angle corresponding to the maximum steering angle. This allows the arrangement to be specifically adapted to the available installation space and / or the functionality of a steering sensor system. In particular, this makes it possible to install the sensor arrangement in a non-functional area of ​​a steering system, which can thus be used without the overall system having to be enlarged by special areas / volumes. To limit the angular extent of the steering sensor arrangement, the position of all movable components, e.g., the sensor counterpart, can be in the center of the fixed components, e.g., the sensor, when the steering angle is in the middle of the full steering travel, e.g., 0° with a symmetrical steering angle.After installation, the steering sensor assembly can, for example, be calibrated to indicate 0° when the rotating component or, for example, a wheel connected to the rotating component is straight, i.e., at right angles to the stationary component.

[0009] The sensor and / or the sensor counterpart may comprise a sensor housing or a sensor counterpart housing. For example, the sensor and / or the sensor counterpart may comprise a housing that extends circumferentially around the steering axis, particularly within the detection range. The sensor and the sensor counterpart may be in contact with each other or arranged at a limited distance of at most 0.1 mm, 0.5 mm, or 1 mm from each other. This may ensure the functionality of the arrangement and / or protect it from the ingress of dirt.

[0010] The sensor counterpart can be a wireless sensor counterpart. The sensor counterpart can be, for example, a passive component, such as a magnet, that requires no electronics at all. In contrast, the sensor can be a wired sensor. In other words, the sensor can include active components that are wired or wirable to an external component, such as a power source, a processing unit, or the like. Thus, only the sensor that is permanently connected to the stationary component can have external wiring, thus avoiding excessive wear on the assembly.

[0011] The sensor can be a resistance sensor, a capacitive sensor, a magnetic sensor, or an optical sensor, for example, an optical or magnetic encoder or a magnetic resolver. The sensors to be used can generally be known sensors adapted to the present embodiments, particularly with regard to the extent of the sensor and / or sensor counterpart arrangement within a limited detection range and / or the relative arrangement of any stationary and moving parts.

[0012] The sensor can be, for example, a resistance sensor, particularly a potentiometer, with a variable effective electrical length. The effective electrical length can depend on the position of the sensor counterpart around the steering axis. A corresponding sensor structure can be designed particularly simply and adaptively.

[0013] In this case, the sensor can comprise an electrically conductive sensor bridge that is movably coupled to the sensor counterpart, so that the effective electrical length is varied upon joint movement of the sensor bridge and the sensor counterpart. The sensor can comprise at least two electrically conductive rails that extend circumferentially around the steering axis, in particular within the detection range. The sensor bridge can be movably guided on the conductive rails and short-circuit them together. In this case, the resistance, which is proportional to the effective electrical length of the conductive rails, which in turn is related to the steering angle, is determined by creating an electrical short circuit between the conductive rails integrated in the sensor. The short circuit can be determined by the sensor bridge, which is connected to the rotating sensor counterpart, which can be rigidly attached to the rotating component.The conductive rails can be connected or connectable to a power source. The sensor bridge and the sensor counterpart can be spaced apart. Their distance can be limited to no more than 0.5 mm, 1 mm, or 5 mm. The sensor bridge can be magnetically coupled to the sensor counterpart. The sensor bridge can, for example, consist of or comprise a ferromagnetic material and / or a sensor magnet. The sensor counterpart can consist of or comprise a counter magnet that is magnetically coupled to the sensor bridge. The sensor can comprise a sensor housing that encloses the sensor bridge and / or the sensor rails. The sensor rails can be fixedly arranged inside the sensor housing. The sensor bridge can be movably arranged within the housing. The sensor housing, the sensor rails, and / or the power source can be rigidly fixed with respect to the steering axis.For example, a counter magnet of the sensor counterpart, which is permanently attached to the rotating component, can slide against the outer housing of the non-rotating sensor in contact or with a limited air gap, as previously described. A sensor bridge, magnetically connected to the counter magnet, e.g., via a sensor magnet provided with the sensor bridge, can be arranged inside the sensor housing near the sensor counterpart. A resulting small gap between the two magnets can ensure free sliding of the parts with limited friction and secure the magnetic connection of the sensor bridge to the sensor counterpart.

[0014] In another example of the sensor arrangement, the sensor can be a magnetic resolver. In this case, the sensor counterpart can comprise a magnetic strip, in particular a magnetic strip that extends within the detection range. The sensor can be an electronic sensor and in particular consist of or comprise electrically conductive coils. In this case, a movement of the magnetic strip caused, for example, by the steering angle can induce an alternating current in the coils whose phase is proportional to the steering angle. The magnetic strip can be housed in a housing of the sensor counterpart. The coils of the sensor can be housed in a sensor housing.The sensor housing and the sensor counterpart housing may be in contact with each other or arranged at a limited distance of not more than 0.1 mm, 0.5 mm or 1 mm from each other to ensure free sliding of the two parts and at the same time provide an electronic coupling that can indicate a steering angle.

[0015] A steering sensor system is also proposed. The steering sensor system comprises a stationary component, a rotatable component mounted on the stationary component for rotation about a steering axis, and a steering sensor arrangement spaced radially from the steering axis. The steering sensor arrangement may be of the type described above. The radial distance may be at least 1 cm, 5 cm, or 10 cm, and at most 5 cm, 10 cm, or 30 cm.

[0016] The sensor system, in which the sensor and the sensor counterpart are arranged off-center to the steering axis, can simplify installation and / or reduce excessive wear, especially since the sensor arrangement can be arranged in a usually less functional area of ​​the stationary and rotating component.

[0017] The stationary component may be an axle. The rotating component may be a steering knuckle rotatably mounted on the axle. The axle may be, for example, an axle or, more specifically, an axle housing of a steering axle of a two-track vehicle. The steering knuckle may be rotatably attached to the axle via a kingpin extending along the steering axis.

[0018] The steering sensor assembly is mounted at a radial distance from the steering kingpin. This allows the steering sensor assembly to be housed in a less functional area of ​​the steering sensor system, further simplifying installation and further reducing stress and wear. The radial distance can be a minimum of 1 cm, 5 cm, or 10 cm, and a maximum of 5 cm, 10 cm, or 30 cm.

[0019] The steering sensor arrangement may comprise a sensor that is at least partially fixedly attached to the stationary component or the axle, in particular to an outer side of the stationary component. In particular, the sensor may comprise a sensor housing that is firmly and rigidly attached to the stationary component. In the previously described potentiometer arrangement, for example, all components of the sensor may be fixed relative to the stationary component, with the exception of the sensor bridge, which may be movably or displaceably accommodated in the sensor housing. A sensor counterpart of the steering sensor arrangement may be fixedly attached to the rotatable component or the steering knuckle, in particular to an outer side of the rotatable component. This enables a simple installation method as well as good maintenance in the event of damage to the sensor or the sensor counterpart, without having to remove other components.A corresponding connection can be established by a screw connection. The sensor counterpart can be at least partially fixedly arranged in a pocket of the rotatable component. This allows the sensor counterpart to be better attached to the rotatable component and at the same time protected from external influences. The pocket can be designed as a projection extending from the rotatable component. The steering knuckle can, for example, have a pocket or projection for at least partially receiving the sensor counterpart. In the case of the potentiometer arrangement described above, the sensor counterpart, e.g. a counter magnet, can be fully or partially enclosed in the pocket, with only one side of the pocket facing the sensor or sensor housing being open.

[0020] As already described above, the sensor and / or the sensor counterpart may extend at least partially in the circumferential direction around the steering axis and / or the sensor counterpart may be movable in the circumferential direction around the steering axis, optionally in a detection range that covers a center angle of not more than 225°, 180° or 120° and / or not less than 30°, 60° or 90° and / or covers a center angle that corresponds to a maximum steering angle of the rotatable component relative to the stationary component.

[0021] Several embodiments have been disclosed herein. From the following detailed description, which shows and describes two exemplary embodiments of the invention, further embodiments of the present invention and suitable combinations of features will become apparent to those skilled in the art. Accordingly, the figures and the detailed description are to be considered as exemplary and not restrictive. Recurring features are designated by the same reference numerals in the description of the accompanying figures. Fig. 1 a perspective sectional view of a steering sensor system according to the prior art, Fig. 2 is a schematic representation of a steering sensor system with a steering sensor arrangement according to an embodiment of the present disclosure, Fig. 3 a first perspective view of the steering sensor system Fig. 2, Fig. 4 another perspective view of the steering sensor system Fig. 2, Fig. 5 a schematic view of an exemplary sensor layout, Fig. 6 is a schematic view of a steering sensor system including a steering sensor arrangement according to another embodiment of the present disclosure, Fig. 7 a first perspective view of the steering sensor system from Fig. 6 and Fig. 8 another perspective view of the steering sensor system Fig. 6.

[0022] Fig. 1 shows a prior art steering sensor system. Therein, a sensor 110' is mounted coaxially with a steering axis R and fixedly attached to a kingpin 30 extending along the steering axis R. The kingpin 30 is fixedly attached to a steering knuckle, which is thereby rotatable about the steering axis R relative to an axle 10. The sensor 110' is designed to measure a steering angle about the steering axis R of the steering knuckle relative to the axle and must be wired to a power source and a processing unit. When the steering knuckle rotates relative to the axle about the steering axis R, the sensor 110' rotates with it, causing excessive wear on the cable. Furthermore, because the sensor 110' is housed in a highly functional area of ​​the steering sensor system, installation and maintenance can be difficult.

[0023] The Fig. 2, Fig. 3 and Fig. 4 show an exemplary steering sensor system 1 with a first exemplary embodiment of a steering sensor arrangement 100, while the Fig. 6, Fig. 7 and Fig. 8 shows a steering sensor system 1 with a second exemplary embodiment of a steering sensor arrangement 100'. A more specific sensor arrangement is shown in Fig. 5, which can be provided in the first embodiment of the steering sensor assembly 100. In the following, recurring features are described once for all figures. Reference is made to individual figures only when appropriate or when differences or alternatives are intended to be demonstrated.

[0024] The steering sensor system 1 comprises a stationary component 10, a rotatable component 20 mounted on the stationary component 10 for rotation about a steering axis R, and a steering sensor assembly arranged radially spaced from the steering axis R. In particular, the steering sensor assembly 100, 100' may be of the type described below.

[0025] The steering sensor arrangement 100, 100' for detecting a steering angle between a stationary component 10 and a rotatable component 20 mounted on the stationary component 10 so as to be rotatable about a steering axis R comprises a sensor 110 which is at least partially stationary with respect to the steering axis R and a sensor counterpart 150 which is movable about the steering axis R. The sensor and the sensor counterpart are arranged at a distance from the steering axis.

[0026] The radial distance may be a minimum of 1 cm, 5 cm or 10 cm and a maximum of 5 cm, 10 cm or 30 cm.

[0027] The stationary component 10 here is an axle, and the rotatable component 20 is a steering knuckle rotatably mounted on the axle. The axle can be, for example, an axle or, more precisely, an axle housing of a steering axle of a two-track vehicle. The steering knuckle is rotatably mounted on the axle via a kingpin 30, with the kingpin 30 extending along the steering axis R. The steering sensor arrangement 100, 100' is arranged at a radial distance from the kingpin 30. The radial distance can be at least 1 cm, 5 cm, or 10 cm, and at most 5 cm, 10 cm, or 30 cm.

[0028] Following the example of Fig. 2 - 5, the sensor 110 and the sensor counterpart 150 are arranged at the same radial distance from the steering axis R. According to the example of Fig. 6 - 8, the sensor 110 and the sensor counterpart 150 are arranged at different radial distances in a plane orthogonal to the steering axis R.

[0029] Following the example of Fig. 2 - 5, the sensor 110 extends circumferentially around the steering axis R. According to the example of Fig. 6 - 8, the sensor counterpart 150 extends circumferentially around the steering axis R. In both cases, the sensor counterpart 150 is movable circumferentially around the steering axis R. In particular, the circumferential movement of the sensor counterpart 150 is coupled to the rotation of the rotatable component 20 relative to the stationary component 10 about the steering axis R. A resulting movement and / or extension range, also referred to as the detection range 200, covers a limited area. Here, the center angle is 180°. In general, the center angle can be no more than 225°, 180°, or 120° and / or no less than 30°, 60°, or 90°. The center angle of the detection range 200 can correspond to the maximum steering angle of the rotatable component 20 relative to the stationary component 10.In other words, the sensor arrangement 100, 100' is not completely circular, but has a semicircular shape with an angular extent that can cover the entire steering angle corresponding to the maximum steering angle. In order to limit the angular extent of the steering sensor arrangement 100, 100', the position of all movable components, e.g., the sensor counterpart 150, is in the center of the fixed components, e.g., the sensor 110, when the steering angle is in the middle of the full steering travel, e.g., 0° for a symmetrical steering angle. For example, the steering sensor arrangement 100, 100' can be calibrated after installation so that it indicates 0° when the rotating component 20 or, for example, a wheel coupled to the rotating component 20 is straight, i.e., at right angles to the stationary component 10.

[0030] The sensor 110 comprises a sensor housing 130. According to the example of Fig. 6 - 8, the sensor counterpart 150 comprises a sensor counterpart housing 190. The sensor housing 130 and the sensor counterpart housing 190 extend circumferentially around the steering axis R within the detection area 200. The sensor 110 and the sensor counterpart 150 can touch each other or be arranged at a limited distance of at most 0.1 mm, 0.5 mm or 1 mm from each other.

[0031] The sensor counterpart 150 is a wireless sensor counterpart. Specifically, the sensor counterpart 150 is a passive component, such as a magnet, that does not require any electronics. In contrast, the sensor 110 is a wired sensor, which in this case is connected to a power source 300. The sensor can be a resistive sensor, a capacitive sensor, a magnetic sensor, or an optical sensor, for example, an optical or magnetic encoder or a magnetic resolver.

[0032] According to the Fig. 2 to 5, the sensor 110 is a resistance sensor, in particular a potentiometer, with a variable effective electrical length. The effective electrical length depends on the position of the sensor counterpart 150 around the steering axis R.

[0033] According to this exemplary embodiment, the sensor 110 comprises an electrically conductive sensor bridge 120, which is movably coupled to the sensor counterpart 150, such that the effective electrical length is varied upon joint movement of the sensor bridge 120 and the sensor counterpart 150. The sensor 110 comprises two electrically conductive rails 121, 122, which extend circumferentially around the steering axis R within the detection area 200. The sensor bridge 120 is movably guided on the conductive rails 121, 122 and short-circuits them together. In this case, the resistance, which is proportional to the effective electrical length of the conductive rails 121, 122, which in turn is related to the steering angle, is determined by creating an electrical short-circuit connection between the two conductive rails 121, 122 integrated in the sensor 110.The short circuit is determined by the sensor bridge 120, which is connected to the rotating sensor counterpart 150, which is rigidly attached to the rotating component 20. The conductive rails 121, 122 are connected to the power source 300. The sensor bridge 120 and the sensor counterpart 150 are arranged at a distance from each other. Their distance can be limited to no more than 0.5 mm, 1 mm, or 5 mm. The sensor bridge 120 is magnetically coupled to the sensor counterpart 150. The sensor bridge 120 can consist of or comprise a ferromagnetic material and / or a sensor magnet. The sensor counterpart 150 can consist of or comprise a counter magnet that is magnetically coupled to the sensor bridge 120. The sensor counterpart 150 here is a counter magnet 160. The sensor housing 130 encloses the sensor bridge 120 and the sensor rails 121, 122. The sensor rails 121, 122 are fixedly arranged inside the sensor housing 130.The sensor bridge 120 is movably mounted within the housing 130. The sensor housing 130, the sensor rails 121, 122, and the power source 300 are rigidly mounted with respect to the steering axis R, i.e., with respect to the stationary component 10 or the axle. The counter magnet 160 of the sensor counterpart 150 is fixedly attached to the rotating component 20 or the steering knuckle and can slide against the outer sensor housing 130 of the non-rotating sensor 110 in contact with, or with a limited air gap, as previously described. The sensor bridge 120, magnetically connected to the counter magnet 160, e.g., via a sensor magnet provided with the sensor bridge 120, is arranged within the sensor housing 130 near the sensor counterpart 150.

[0034] According to the second example of the sensor arrangement 100' in the Fig. 6 to 8, the sensor 110 is a magnetic resolver. In this case, the sensor counterpart 150 comprises a magnetic strip 160' extending within the sensing area 200. The sensor 110 is an electronic sensor and includes electrically conductive coils. The magnetic strip 160 is housed in a sensor counterpart housing 190. The coils of the sensor 110 are housed in the sensor housing 130. The sensor housing 130 and the sensor counterpart housing 190 can touch each other or be arranged at a limited distance of no more than 0.1 mm, 0.5 mm, or 1 mm from each other.

[0035] As previously described, the steering sensor arrangement 100, 100' comprises a sensor 110 that is at least partially fixedly attached to the stationary component 10 or the axle, in particular on an outer side of the stationary component 10. In particular, the sensor 110 comprises a sensor housing 130 that is firmly and rigidly attached to the stationary component 10. For example, in the previously described potentiometer arrangement, all components of the sensor 110 are fixed relative to the stationary component 10, with the exception of the sensor bridge 120, which is movably or slidably accommodated in the sensor housing 130. The sensor counterpart 150 of the steering sensor arrangement 100, 100' is fixedly attached to the rotatable component 20 or the steering knuckle, in particular on an outer side of the rotatable component 20. A corresponding connection to the stationary component 10 or to the rotatable component 20 is provided by a screw connection 99.The sensor counterpart 150 is at least partially fixedly disposed within a pocket 25 of the rotatable component 20 or knuckle. The pocket 25 is formed as a projection extending from the rotatable component 20. In the previously described potentiometer arrangement, see . Fig. 3 and Fig. 4, the sensor counterpart 150 and in particular the counter magnet 160 is partially enclosed in the pocket 25, wherein the side of the pocket 25 facing the sensor 110 or the sensor housing 130 is open.
