Description

[0001] Connector, linear drive, steering system and vehicle

[0002] The present invention relates to a connector for connecting a coupling element to a nut of a linear unit, a linear drive with such a connector, a steering system with such a linear drive and a vehicle with such a steering system.

[0003] Linear movements, for example, for operating machine parts, can be generated using linear drives. Such linear drives can, for example, have a linear unit that converts the rotational movement of a motor shaft into a translational movement. Another common type of linear drive is a hydraulic cylinder.

[0004] Electromechanical linear drives which have a linear unit have advantages over hydraulic cylinders in terms of their efficiency, rigidity and positionability, among other things. In addition, they can be operated without hydraulic fluid or oil. However, the linear unit takes up a certain amount of space, so that linear drives with a linear unit usually have a poorer ratio of overall length to stroke (in short: stroke-length ratio) than hydraulic cylinders. In particular, there is the problem of connecting a component to be moved to a nut of the linear unit in a space-saving manner. This is usually done using a push rod which is attached to the nut and extends out of a housing of the linear actuator when the nut moves in translation.Therefore, hydraulic cylinders used in space-critical applications, for example in vehicles such as forklift trucks, tractors and aircraft tractors, aerial work platforms or personnel lifts, agricultural machinery or other mobile applications, cannot be replaced by electromechanical linear drives without effort.

[0005] It is an object of the invention to improve the connection of a coupling element with the nut of a linear unit, in particular to make it more compact.

[0006] This object is achieved by a connector for connecting a coupling element to a nut of a linear unit, a linear drive, a steering system and a vehicle according to the independent claims.

[0007] Preferred embodiments are the subject of the dependent claims and the following description.

[0008] A first aspect of the invention relates to a connector for the, in particular mechanical, connection of a coupling element to a nut of a linear unit, in particular a ball screw drive. A body of the connector has, preferably at a first end of the body, a first fastening section for mounting on a nut of a linear unit. The body also has, in particular at a second end opposite the first end, a second fastening section for mounting on the coupling element, in particular such that the coupling element runs parallel to the axis of movement.

[0009] The body is expediently designed in such a way that the first fastening section, when mounted on the nut, lies together with the second fastening section essentially on a transverse axis of the body which is perpendicular to the axis of movement of the nut.

[0010] A coupling element within the meaning of the invention is preferably a component or an assembly which is provided for coupling an external load to the nut, in particular to the linear drive comprising the nut. The coupling element is expediently designed in the shape of a rod. It can pass through a housing in which the nut, in particular the linear drive, is arranged, in order to transmit a movement carried out by the nut to the load. The coupling element is preferably a steering rod, occasionally also referred to as a tie rod, of a steering system, in particular of an axle pivot steering system.

[0011] One aspect of the invention is based on the approach of providing a direct, in particular rigid and immediate, connection between the nut of a linear unit and a coupling element intended for movement with the nut. For this purpose, a connector is provided which is essentially formed by a one-piece or multi-piece body. The body can be elongated, but other shapes are also conceivable in principle. The body is expediently designed such that a first end of the body can be mounted on the nut, while the opposite second end can be mounted on the coupling element. The body can therefore expediently be arranged essentially, at least for the most part, between the nut and the coupling element.

[0012] The body expediently has a first fastening section which is designed for mounting on the nut. Correspondingly, the body also has a second fastening section which is designed for mounting on the coupling element. When mounted on the nut and the coupling element, the body expediently extends between the first and second fastening sections substantially transversely to a movement axis of the nut. Consequently, the connector enables a shorter connection between the nut and the coupling element than is achievable via a conventional torque tube.

[0013] The axial dimensions of the body and the nut are preferably substantially identical or at least similar. For example, the first fastening section can be designed such that, when mounted on the nut, the body protrudes substantially not axially beyond the nut, or protrudes only slightly, for example only by 10% or less of its axial dimension. Particularly preferably, the body is even axially shorter than the nut. As a result, the connector is not axially constructed, which enables a linear drive that is at least axially compact.

[0014] The terms "axial" and / or "radial" preferably refer to the axis of movement of the nut of the linear unit. The axis of movement of the nut expediently corresponds to a longitudinal axis of the linear unit, in particular to a rotational axis of a shaft of the linear unit that is operatively connected to the nut, such as a screw or (threaded) spindle.

[0015] Using such a connector, a connection can also be established between the coupling element and the nut, in which the coupling element's center of gravity is axially aligned with the nut, and the connector is mounted on the coupling element in the area of ​​this center of gravity. For example, the connector can be mounted centrally on the coupling element so that the coupling element is arranged symmetrically with respect to the nut.

[0016] Using the connector, a stroke-to-length ratio similar to that of a hydraulic cylinder can be achieved. When used in a drive-by-wire system, a hydraulic cylinder can thus, in principle, be replaced by a linear drive with the connector according to the invention, at least with regard to the required installation space.

[0017] The connector also enables better, particularly direct, force transmission from the nut to the coupling element or vice versa, especially when the connector is mounted centrally on the coupling element or near its center of gravity. This can potentially reduce the moments acting on the nut.

[0018] Preferred embodiments of the invention and their further developments are described below. These embodiments can be combined with each other and with the aspects of the invention described below, unless expressly excluded.

[0019] In a preferred embodiment, the body in the first fastening section is designed for pivotal mounting on the nut. The body can in particular be pivotally mounted about a pivot axis running transversely to the axis of movement. This makes it possible to absorb moments on the nut resulting from axial forces acting on the coupling element. This can counteract, for example, tilting of the nut relative to the shaft operatively connected to the nut and the resulting inhomogeneous force transmission from the nut to the shaft along the axis of movement. Ultimately, the pivotal mounting has a positive effect on the service life of the nut and / or the shaft.

[0020] In a further preferred embodiment, the body in the first fastening section is designed to at least partially receive the nut. Alternatively or additionally, the body in the second fastening section is designed to at least partially receive the coupling element. In the case of partial reception, the body preferably at least partially encompasses the nut or the coupling element. For example, the nut or the coupling element can be at least partially inserted into the body. This ensures that the body sits firmly on the nut or the coupling element. In particular, it can be ensured that forces transmitted by means of the connector act homogeneously on the nut or the coupling element.

[0021] The at least partial inclusion of the nut in the first fastening section also allows the body to pivot relative to the center of the nut. This also enables the body to be attached to the nut laterally.

[0022] In a further preferred embodiment, the first fastening section has an axial bore for at least partially receiving the nut. Alternatively or additionally, the second fastening section can have an axial bore for at least partially receiving the coupling element. This allows the nut or coupling element inserted into the bore to be protected by the body and, if necessary, secured against rotation.

[0023] In a further embodiment, the bore in the first fastening section is designed such that the nut has play therein. The bore in the first fastening section can in particular be designed with a clearance fit in relation to the nut. In this case, play is preferably at least slight mobility of the nut in the bore. In other words, the nut is expediently mounted or can be mounted in the bore so as to be movable, in particular pivotable. As a result of the play, the transmission of a tilting moment from the nut to the shaft can therefore be prevented or at least reduced, with the advantages already mentioned above.

[0024] In a further preferred embodiment, the body in the first fastening section has two opposing pins about which the body can be pivotally mounted on the nut. Alternatively, the body in the first fastening section can have two opposing pin receptacles. The pin receptacles are expediently provided for receiving corresponding pins of the nut for pivotally mounting the body on the nut. The pivot axis can be defined by such pins or pin receptacles. The pins or pin receptacles allow reliable pivotable mounting of the body on the nut, with the advantages already mentioned above.

[0025] In a further preferred embodiment, the body in the second fastening section is designed for pivotally supporting the coupling element. The body can be designed in the second fastening section for pivotally supporting the coupling element, in particular about a pivot axis extending transversely to the movement axis. It is also conceivable for the coupling element to be a split coupling element, with at least two parts of the coupling element being pivotably mounted separately on the body.

[0026] The pivotable mounting of the coupling element enables a dynamic connection of the coupling element to the nut. For example, a split handlebar of a steering system can be connected separately to the nut, so that the handlebar no longer has to run rigidly parallel to the nut's axis of movement, but the two parts of the handlebar can be tilted relative to the axis of movement. In a further preferred embodiment, the body has at least one pin in the second fastening section, about which the coupling element can be pivotally mounted. Alternatively, the body can have at least one pin receptacle in the second fastening section. The pin receptacle is expediently provided for receiving a corresponding pin of the coupling element for the pivotable mounting of the coupling element on the body. The pivot axis can be defined by such a pin or pin receptacle. The pin orThe pin holder allows a reliable pivoting mounting of the coupling element on the body.

[0027] A second aspect of the invention relates to a linear drive with a linear unit having a shaft and a nut running on the shaft. The nut is expediently axially movable by rotation of the shaft. The linear drive also has a connector mounted on the nut according to the first aspect of the invention.

[0028] The linear unit is preferably designed as a ball screw drive. The shaft is then expediently designed as a spindle with helical raceways for balls, by means of which the nut rolls on the spindle. However, a linear unit designed as a planetary screw drive is also conceivable. The shaft is then expediently designed as a screw with a thread for engaging the threads of planetary rollers. In principle, however, the shaft can also be a screw onto which the nut is screwed directly.

[0029] The connector allows the linear drive to be particularly compact axially. In particular, a thrust tube is eliminated. Consequently, a stroke-to-length ratio comparable to that of a double-acting hydraulic cylinder can be achieved. Such a linear drive is therefore advantageously used in steering systems, for example, for forklifts, tractors, airport vehicles, work platforms such as scissor or mast lifts, agricultural machinery, and / or the like.

[0030] In a preferred embodiment, the linear drive comprises a housing in which the shaft is rotatably mounted and the nut is movably mounted on the shaft. Preferably, the housing also houses the connector, in particular completely. Alternatively or additionally, the housing is also designed for the movable mounting and / or guidance of a coupling element, in particular a steering rod, connected to the nut by means of the connector.

[0031] The housing allows radial forces, i.e., forces acting perpendicular to a longitudinal axis of the coupling element, to be absorbed by the housing. Loads on the linear unit can be avoided or at least reduced. Moments acting on the nut, which result from axial forces on the coupling element, can be particularly advantageously avoided or at least reduced by pivoting the body on the nut. This can significantly increase the service life of the linear unit.

[0032] In addition, the housing of the connector can be advantageous in terms of protection, for example by seals and so-called "wipers" on the housing. In addition, the housing of both the linear unit and the connector allows a robust and, if necessary, modular design. For example, different drives or gears can be coupled to the linear unit by fastening to the housing. A third aspect of the invention relates to a steering system with at least one linear drive according to the second aspect of the invention. The steering system has a steering system, in particular a kingpin steering system. A component of the steering system, in particular a steering rod, is mounted on the nut of the linear drive by means of the connector.

[0033] This makes it possible to design the steering system with a particularly compact design. The use of the linear drive can increase efficiency compared to hydraulically operated steering systems. In particular, the service life of the nut and / or the shaft can be increased compared to steering systems with a conventional coupling of the nut and the steering rod, since radial forces can be absorbed almost entirely by the linear drive housing via the sliding bearings of the steering rod and are not transferred to the nut due to the complete enclosure of the connector.

[0034] In a preferred embodiment, the steering rod is mounted symmetrically to the nut of the linear drive by means of the connector, for example, in an area of ​​its center of gravity or in its center, so that the longitudinal rod runs essentially parallel to the shaft of the linear drive. Mounting the longitudinal rod in this way requires significantly less installation space than connecting the longitudinal rod to the nut via a push tube.

[0035] In a further preferred embodiment, the steering rod is designed as a split steering rod. In particular, the steering rod can act as a tie rod, especially if it is pivotally mounted on the connector or the body. A fourth aspect of the invention relates to a vehicle with a steering system according to the third aspect of the invention. Such a vehicle can be operated more efficiently than vehicles with hydraulically actuated steering. In addition, more precise steering settings can be achieved.

[0036] The invention is explained in more detail below with reference to figures. Where appropriate, elements with the same effect are provided with the same reference numerals. The invention is not limited to the exemplary embodiments shown in the figures - not even with regard to functional features. The previous description as well as the following description of the figures contains numerous features, some of which are summarized in the dependent claims. However, a person skilled in the art will also consider these features, as well as all other features disclosed above and in the following description of the figures, individually and combine them to form further useful combinations.In particular, all of the features mentioned can be combined individually and in any suitable combination with the connector according to the first aspect of the invention, the linear drive according to the second aspect of the invention, the steering system according to the third aspect of the invention and the vehicle according to the fourth aspect of the invention.

[0041] Side view; Fig. 4 shows the connector from Figure 3 in a cross-sectional view;

[0042] Fig. 5 shows an example of a connector for pivotally supporting a coupling element; and

[0043] Fig . 6 an example of a vehicle with a steering system .

[0044] Figure 1 shows an example of a connector 2 for connecting a coupling element (not shown) to a nut (not shown) of a linear unit in a side view. The connector 2 has a body 4 with a first fastening section 6 for mounting on the nut and a second fastening section 8 for mounting on the coupling element.

[0045] The connector 2 is expediently designed to at least partially accommodate the nut and the coupling element. For this purpose, the body 4 has a bore 10, indicated by dashed lines, in the first fastening section 6, which runs axially—i.e., parallel to the movement axis X—through the body 4. The nut can be arranged in this bore 10, preferably with some play, so that the body 4 can be pivoted or tilted at least slightly relative to the nut, in particular about a pivot axis S transverse to the movement axis X.

[0046] Preferably, the body 4 is provided in the second fastening section 8 with a corresponding bore 12, indicated by dashed lines, for receiving the coupling element. The bore 12 expediently runs parallel to the bore 10 in the first fastening section 6 and thus axially through the body 4. The parallel course of the bores 10, 12 in the first and second fastening sections 6, 8 ensures that the coupling element is aligned parallel to the nut or the movement axis X when connected to the nut via the connector 2.

[0047] The body 4 is preferably designed such that a center of gravity of the body 4, or the body center M, is located between the first and second fastening sections 6, 8, and thus—during use—between the nut and the coupling element. This is particularly space-saving. Furthermore, the coupling element can thus be held at a predefined distance predetermined by a length L of the body 4.

[0048] When mounted on the nut, the body 4 extends substantially parallel to a transverse axis Q perpendicular to the movement axis X. Advantageously, the extension of the body 4 along the transverse axis Q is greater than along a longitudinal axis (not shown) aligned parallel to the movement axis X.

[0049] With respect to the transverse axis Q, the body 4 has a first end 14 and an opposite second end 16. The first fastening portion 6 is arranged at the first end 14 of the body 4, while the second fastening portion 8 is arranged at the second end 16.

[0050] Figure 2 shows an example of a linear drive 20 with a linear unit 22 for converting a rotational movement, for example of a motor shaft 24 of a motor 26, into a translational movement along a movement axis X. For this purpose, the linear unit 22 has a shaft 28, such as a screw or a (threaded) spindle, and a nut 30 running on the shaft 28. The linear unit 22 is arranged in a housing 32, which also houses a connector 2 for connecting a coupling element 34 to the nut 30. The shaft 28 is rotatable by means of a bearing arrangement 36 in the

[0051] Housing 32 is mounted. The shaft 28 is operatively connected to a position sensor 38 for determining the position of the nut 30.

[0052] In the example shown, the motor 26 is connected to the shaft 28 via a gearbox 40 in a so-called "U-configuration". The gearbox 40 is located in a gear box 42, which is connected to the housing 32. Alternatively, the motor 26 can also be aligned in a so-called "L-configuration" or, if necessary, connected directly to the shaft 28 in a so-called "inline configuration".

[0053] The connector 2 has a body 4, which is mounted in a first fastening section 6 on the nut 30 and in a second fastening section 8 on the coupling element 34. In the present example, the body 4 is designed such that it does not protrude axially beyond the nut 30. Alternatively, however, the body 4 can also have an axial extension that is at least slightly, approximately 10% or less, greater than the axial extension of the nut 30.

[0054] Conveniently, the housing 32 has an opening 46 on each of two opposite sides, through which the coupling element 34 can pass. This not only makes it possible to mount the body 4 on the coupling element 34 inside the housing 32, but also to guide a movement of the coupling element 34 by means of the housing 32. In particular, the coupling element 34 can be supported radially on the housing 32.

[0055] At the openings 46, the linear drive 20 expediently has bearings 48 for the movable mounting of the coupling element 34, for example in the form of sliding rings. These bearings 48 expediently serve to absorb radial forces acting on the coupling element 34. Consequently, a transmission of the radial forces via the connector 2 to the nut 30 or the shaft 28 can be avoided or at least significantly reduced.

[0056] Alternatively or additionally, sealing means (not shown) for sealing the housing interior from the environment can also be provided at the openings 46, for example in the form of so-called "wipers". These wipers can also be designed under certain circumstances to prevent or at least reduce the leakage of lubricant from the housing 32.

[0057] Figure 3 shows an example of a connector 2 for connecting a nut 30 to a coupling element 34 within a housing 32 of a linear drive (not shown in detail) in a side view. A body 4 of the connector 2 is mounted in a first fastening section 6 at a first end 14 of the body 4 on the nut 30 and in a second fastening section 8 at a second end 16 of the body 4 on the coupling element 34. For (sliding) mounting on the housing 32, the connector 2 can have sliding elements 44 at the first end 14 of the body 4. Correspondingly, the connector 2 can also have sliding elements 44 at the second end 16.

[0058] In the first fastening section 6, the body 4 is pivotably mounted on the nut 30 about a pivot axis S perpendicular to the plane of the drawing, as indicated by the double arrow. This is explained in more detail below in connection with Figure 4.

[0059] The body 4 is mounted to the coupling element 34 by fastening means 50. In the example shown, the fastening means 50 are designed as screws; however, in principle, other fastening means may also be provided, or the mounting of the body 4 to the coupling element 34 may be carried out in another way.

[0060] Figure 4 shows an example of the connector 2 from Figure 3 in a cross-sectional view.

[0061] For the pivotable mounting of the body 4 on the nut 30, the connector 2 has opposite pin receptacles 18 in the first fastening section, which serve to receive corresponding pins 52 of the nut 30. The pin receptacles 18 can be provided as bores or blind holes in the body 4, in particular in the inner wall of a bore 10 in the body 4 (cf. Figure 1). The pin receptacles 18 are expediently located on both sides of the body 4, so that the pivot axis S defined by them is aligned transversely to the movement axis X, and preferably also transversely to a transverse axis Q (cf. Figure 1), i.e. to the longitudinal extent of the body 4.

[0062] To improve the pivotability, the pin receptacles 18 can, as shown in the present example, comprise bearing means for supporting the pins 52.

[0063] In principle, the pivotable mounting of the nut 30 on the body 4 can also be achieved in that the body 4 has the pins 52, while the pin receptacles 18 are provided on the nut 30.

[0064] Due to the pivotable mounting of the body 4 on the nut 30, axial forces acting on the coupling element 34, which would otherwise cause a tilting moment on the nut 30, can be absorbed. In particular, an inhomogeneous force transmission from the nut 30 to the shaft 28 resulting from such a moment can be avoided.

[0065] The body 4 preferably has a "dogbone shape" in cross-section. This means that the body 4 tapers in the area around its center M compared to its two ends 14, 16. This shape allows precise guidance of the connector 2 in the housing 32. In particular, the connector 2 can thus serve as an anti-twist device for the nut 30. By being mounted on the nut 30, the body 4 guided by the housing 32 can prevent the nut 30 from rotating when the shaft 28 rotates. Consequently, no dedicated guide, for example in the form of a rail or groove, needs to be provided on the housing 32.

[0066] Figure 5 shows an example of a connector 2 for pivotably supporting a coupling element 34. A body 4 of the connector 2 is mounted in a first fastening section 6 with a nut 30 running on a shaft 28 and in a second fastening section 8 on the coupling element 34.

[0067] The connector 2 has at least one pin 62 in the second fastening section 8, two in the example shown, which engage in corresponding pin receptacles (which are not designated by a reference numeral for reasons of clarity) of the coupling element 34. The pins 62 each define a pivot axis about which the coupling element 34 can pivot. In the present example, the coupling element 34 is designed as a split coupling element, with each part being pivotably mounted on the body 4. The parts of the coupling element 34 can be, for example, tie rods of a steering system.

[0068] Figure 6 shows an example of a vehicle 54, for example a forklift truck, a lifting truck / a movable work platform and / or the like, with at least one steering system 56. The steering system 56 has an electromechanical linear drive 20 and a steering system 58. A component of the steering system 58, in this case a steering rod (60), is connected as a coupling element 34 by means of a connector (not shown) to a nut (likewise not shown) of the linear drive 20. The use of the connector makes it possible to dispense with an otherwise conventional push rod and thus enables a space-saving symmetrical arrangement of the linear drive 20 and the steering rod 60 with respect to a vehicle longitudinal axis shown in dash-dotted lines in Figure 6. This can be achieved in particular by centrally mounting the connector on the steering rod 60, i.e. a mounting in the area of ​​the center of the handlebar 60 .In particular, no free space needs to be provided in the vehicle 54 for a push rod extending from a housing of the linear drive 20. At the same time, the connection between the steering rod 60 and the nut can be protected within this housing (see Figure 2).

[0069] The handlebar 60 can also be a split handlebar 60 (see Figure 5).
