Description

Plug-in shaft unit
Technical Field
The invention relates to a plug-in shaft unit. The plug-in shaft unit is provided in particular for a hub of a bicycle having a hub motor. The invention further relates to a bicycle with a hub motor, which bicycle has such a plug-in shaft unit.
Background
The hub on a bicycle with a hub motor requires torque support in the frame of the bicycle. These hubs are nowadays usually realized by means of a double plane (Zweiflach) on the shaft, which fits into a corresponding mating profile in the corresponding epitaxial end (Ausfallenden). In addition, torque support is also achieved by means of a lever which connects the hub axle to the chain support bar.
Disclosure of Invention
The coupling shaft unit according to the invention allows the torque of the motor to be transmitted into the frame in a simple manner without additional components being required. Depending on the torque to be supported or the space requirement, the torque support may be implemented in the hub, in one or both of the outboard ends. The plug-in shaft unit can be assembled and disassembled in a simple manner, in particular without additional tools.
Furthermore, the required lines which have to be led out from the hub motor can be led through the plug-in shaft unit, which results in a small installation space, in addition to which the sensor can be installed in the plug-in shaft unit in a positionally accurate and reproducible manner after disassembly. Furthermore, an electrical interface may be mounted on the shaft, which electrical interface automatically contacts after assembly of the hub motor into the frame.
A hub unit for a bicycle having a hub motor has a first sub-element and a second sub-element separate from the first sub-element. The first sub-element is provided with at least one contour region which can be connected to the frame of the bicycle in a rotationally fixed manner by means of a form fit. The second sub-element can be fastened to the first sub-element. In particular, it is provided here that the second sub-element cannot be connected in a rotationally fixed manner to the stator and/or to the frame. The second sub-element is particularly torsionally movable relative to the first sub-element. The second sub-element can be fastened to the first sub-element or to the first sub-element, in particular by a screw connection.
By forming the contour region on the first sub-element, the first sub-element has a non-circular cross section, for example a flattened portion. By means of the contour region, a torque transmission from the hub motor to the frame of the bicycle can be achieved by means of a form fit.
Preferably, the first sub-element is insertable into the hub and is neither rotatable during assembly nor rotatable during operation. But the first subelement is fixed at all times. This simplifies the assembly of the plug-in shaft unit on the one hand and on the other hand makes it possible to install the cable simply and reliably. Furthermore, the first sub-element of the plug-in shaft unit enables the sensor to be mounted at the same location at all times, since the first sub-element can be reproducibly arranged at all times in the same orientation on the hub and/or the frame. Preferably, the first sub-element extends through substantially the entire hub.
Preferably, the first sub-element is insertable through the opening of the frame. The first sub-element can be received in the opening of the frame either on one side of the hub or on both sides of the hub. The second sub-element is provided in particular for preventing the first sub-element from moving out of the frame and/or from the hub. Preferably, the first sub-element has a first stop which prevents or limits movement of the first sub-element in the first axial direction. Preferably, the second sub-element has a second stop. By mounting the second sub-element on the first sub-element, the second stop is in particular used to prevent or limit movement in a second direction opposite to the first axial direction. The plug-in shaft unit is thereby securely held on the frame.
A preferred embodiment of the invention is shown below.
Preferably, the plug-in shaft unit has a sleeve. The sleeve can be connected to the stator of the hub motor and thus serve to attach the stator to the plug-in shaft unit in a rotationally fixed manner.
Furthermore, the first sub-element preferably has at least one further contour region, which can be connected in a rotationally fixed manner to the stator of the hub motor by means of a form fit. The first sub-element can be arranged in the sleeve in order to be able to be connected to the sleeve in a rotationally fixed manner by means of a form fit via a further profile region. The sleeve may be mounted in particular fixedly in the hub. In order to mount the hub on the frame, it is provided in particular that the first sub-element and/or the second sub-element are inserted through the frame and through the sleeve. Thus, the sleeve simplifies the assembly of the first sub-element and/or the second sub-element.
The further contour region, which is also referred to below as the first contour region, is formed on the first sub-element and causes a rotationally fixed connection between the first sub-element and the sleeve by means of a form fit. The contour region, which is also referred to below as a second contour region, is formed on the first sub-element and, by means of a form fit, brings about a rotationally fixed connection between the first sub-element and the frame of the bicycle.
It is particularly advantageous to form a free space between the sleeve and the first sub-element. In this case, the electrical line can be arranged in free space between the frame and the stator of the hub motor. In particular, the energy supply of the stator can thus be achieved. The cable guiding is simplified by: the sleeve and the first sub-element do not have a relative rotational movement during assembly, but rather, in particular, only a relative axial movement of the sleeve of the first sub-element and the plug-in shaft unit is present.
In a particularly preferred manner, provision is made for the second sub-element to be movable, in particular rotatable, relative to the sleeve. The relative torsionality of the first sub-element and the second sub-element is also obtained by the relative torsionality of the second sub-element and the sleeve. This enables a simple and reliable connection of the first sub-element and the second sub-element.
Advantageously, the sleeve can be connected in a rotationally fixed manner to the first contour region via at least one fastening element. The fastening element brings about a connection between the first contour region and the sleeve by means of a form and/or force fit. The fastening element is for example inserted into a recess, for example a groove, in the first contour region. The fixing element is for example a headless screw. Pins may also be used as the fixing elements. In this way, a rotationally fixed connection between the sleeve and the first sub-element can be established in a simple and reliable manner.
In one advantageous configuration, the first subelement extends through the entire hub. In an alternative advantageous configuration, the second subelement extends only partially within the hub. In the latter case, it is therefore preferably provided that the second subelement is also arranged within the sleeve. In this way, in particular, a single-sided support on the frame can be achieved on one side of the hub. In the first case, however, the second sub-element remains completely outside the sleeve, which is particularly advantageous when supported on the frame on both sides of the hub by the first sub-element.
In one advantageous configuration, the first and/or the second contour region has a biplane and/or a tetraplane and/or a unilateral flattening and/or a groove. The configuration of the contour regions is adapted in particular to the desired height of the torque to be supported. As a result, a greater number of flats are provided, especially in the case of greater torques, since the surface pressure is thereby reduced. This results in avoiding damage to the frame. Furthermore, the contour regions are preferably designed in such a way that a simple assembly/disassembly of the counter element mounted on the contour elements in a rotationally fixed manner is possible.
Preferably, the first contour region and/or the second contour region are formed by consecutive contour regions. Thus avoiding the provision of different contour areas at different locations of the first sub-element. This in particular simplifies the production of the first contour region. By designing the contour regions as identical contour regions in the same manner, it is possible in particular to always transmit the same torque without the risk of damage to the first subelement.
The first subelement has in particular two contour regions. In this case, each second contour region is provided for a form-locking connection with a region of the frame. Preferably, the connection is made to the corresponding associated extension element of the frame. By using two second contour regions, in particular, a torque support on the frame can be achieved on both sides of the hub. Thus, a large torque can be reliably supported.
Advantageously, the first sub-element and the second sub-element are screwed to each other. Thus, a reliable connection exists between the first sub-element and the second sub-element, which can be established and likewise released in a simple manner. When screwing the sub-elements to each other, the ends of the corresponding threads of the first or second sub-element are preferably not reached. Preferably, it is provided that the sub-elements are pressed against one another in the axial direction when the sub-elements are screwed together. This prevents, on the one hand, the subelements from being accidentally unscrewed from each other due to friction between the subelements, and, on the other hand, there is a reliable and firm connection between the subelements.
Advantageously, the first sub-element has a recess. In this recess, the electrical line can be arranged between the frame and the stator of the hub motor. Preferably, the recess extends in the axial direction. The recess preferably extends from a region inside the sleeve and/or the hub to a region outside the sleeve and/or the hub if the first sub-element is in the assembled position. This enables a reliable laying within the recess to the stator. The recess constitutes a cable channel which preferably protects the cable from external influences.
The invention further relates to a system comprising a hub with a hub motor and a plug-in shaft unit. Such a system is provided for being fitted to the frame of a bicycle.
Furthermore, the present invention relates to a bicycle. The bicycle comprises a frame, a hub with a hub motor and a plug-in shaft unit as described above. The stator of the hub motor is connected in a rotationally fixed manner to the plug-in shaft unit. Furthermore, the plug-in shaft unit is connected to the frame in a rotationally fixed manner. Thereby, the stator of the hub motor is supported relative to the bicycle frame. Furthermore, the plug-in shaft unit allows fastening the hub to the frame of the bicycle. Preferably, the cable for the current supply of the stator and/or for the data transmission with the sensor in the hub is arranged in the plug-in shaft unit, particularly advantageously in the first subelement. In particular, it is not necessary to rotate the first sub-element in order to mount the hub on the frame, and this first sub-element is particularly suitable for guiding such cables.

Detailed Description
FIG. 1 schematically illustrates a bicycle 10 in accordance with an embodiment of the present invention. The bicycle 10 has a frame 11 to which the wheels of the bicycle 10 are secured. A plug-in shaft unit 1 is provided here, which connects the hub 2 to the frame 11. Preferably, a hub motor 2a is provided in the hub 2 as a driver of the bicycle 10. The plug-in shaft unit 1 is connected to the frame 11 in a rotationally fixed manner and allows, in particular, a torque support of the hub motor 2a relative to the frame 11.
Fig. 2 schematically shows a hub 2 which is fastened to a frame 11 by means of a plug-in shaft unit 1. For this purpose, the plug-in shaft unit 1 has a first sub-element 3 and a second sub-element 4 that is separate from the first sub-element. Furthermore, the plug-in shaft unit 1 has a sleeve 7. The sleeve 7 is connected in a rotationally fixed manner to the stator 2b of the hub motor 2 a. The connection is preferably realized in a form-locking and/or force-locking and/or material-locking manner.
The first sub-element 3 has at least one first contour region 5 which is connected to the sleeve by a form fit and thus to the stator 2b of the hub motor 2a in a rotationally fixed manner. For this purpose, the first subelement 3 is arranged partly in the sleeve 7. In the embodiment shown, the first subelement 3 passes completely through the sleeve 7 and through the frame 11 at two points, in particular at the outer ends of the frame 11, in order to fasten the hub 2 to the frame 11.
Furthermore, the first sub-element 3 has two second contour regions 6a, 6b, which can be connected in a rotationally fixed manner to the frame 11 of the bicycle 10, in particular to the outer ends of the frame 11, in each case by means of a form fit. Hereby is achieved that the stator 2b of the hub motor 2a is attached to the frame 11 via the sleeve 7 and the first sub-element 3 in a rotationally fixed manner and thus a torque support is achieved.
The second sub-element 4 can be fastened to the first sub-element 3. In the embodiment shown, the first sub-element 3 has a first thread 3a which is screwed with a second thread 4a of the second sub-element 3. The second subelement 4 prevents the first subelement 3 from moving out of the frame 11 and from the hub 2. The first sub-element 3 is provided with a first stop 3b which prevents or limits movement of the first sub-element 3 in the axial direction. By screwing the first thread 3a to the second thread 4a, the second subelement 4 acts as a second stop 4b which acts counter to the direction of the first stop 3 b. Therefore, the disassembly of the plug-in shaft unit 1 can only be achieved by: the first sub-element 3 and the second sub-element 4 are unscrewed from each other. Thus, a safe and reliable fastening of the hub 2 on the frame 11 is achieved.
Furthermore, the plug-in shaft unit 1 allows for a simple assembly of, in particular, a line 9, which serves, for example, as a current supply for the hub motor 2a and/or which is provided for signal transmission between components in the hub 2 and components in or on the frame 11. This is achieved in particular by: the first sub-element 3 is fixed relative to the sleeve 7 and is not rotated, in particular during assembly.
As shown in fig. 3, a free space 8 is preferably formed between the sleeve 7 and the first sub-element 3, wherein an electrical line 9 is routed between the frame 11 and the stator 2b of the hub motor 2a in the free space 8. This aspect enables to reduce the risk of damaging the line 9 during the assembly of the hub 2 on the frame. On the other hand, the line 9 is protected from external influences by the sleeve 7 during operation of the bicycle 10. Furthermore, it is preferred that the sensor can always be arranged on the first sub-element 3 in the desired orientation with respect to the sleeve 7 if the first sub-element 3 can only be introduced into the sleeve 7 in the predetermined orientation with respect to the sleeve 7. Thus, the assembly can be carried out even after the disassembly without the risk of changing the orientation of the sensor or the like. Furthermore, it is preferably possible to mount a plug-in unit on the first sub-element 3, which plug-in unit is in contact with a mating plug of the hub motor 2a mounted in the sleeve 7 when the first sub-element 3 is inserted into the sleeve 7.
Fig. 4A to 4D show different configurations of the first contour region 5 and/or of one of the second contour regions 6a, 6 b. In all cases, it is provided that torque transmission via form-fitting is possible by means of a cross-sectional change.
A biplane is exemplarily shown in fig. 4A. Fig. 4B exemplarily shows a profile with three flattening portions. Fig. 4C shows a profile with one flattening. In fig. 4D, a profile with grooves is shown. In all cases, it is common that a rotationally fixed connection can be produced by means of corresponding complementary shapes or other interactions with the contour regions 5, 6a, 6 b.
Fig. 5A to 5D show different examples of the sleeve 7. An example of a sleeve 7 is shown in fig. 5A, which can be used in particular with the contour shape shown in fig. 4A. Alternatively, the profile shape shown in fig. 4a may also be used with a sleeve as shown in fig. 5B or 5D. In fig. 5B, at least one headless screw 7a, preferably two headless screws 7a, are provided for co-action with one or more planar portions of the contour areas 5, 6a, 6B. The headless screw 7a is an embodiment variant of a fastening element which connects the sleeve 7 to the first sub-element 3 via a form-locking and/or force-locking connection. Fig. 5D shows an example in which a free space 8 remains between the sleeve 7 and the first sub-element 3, in order to guide the line 9 in this free space 8. If such free space is not required, the sleeve 7 as shown in fig. 5D can also be used with the profile areas 5, 6a, 6b shown in fig. 4C. Furthermore, it is possible, for example, to use the contour regions 5, 6a, 6B shown in fig. 4C with the sleeve 7 shown in fig. 5C or to use the contour regions 5, 6a, 6B shown in fig. 4D with the sleeve 7 shown in fig. 5B. It is thus possible to use different configurations in order to produce a rotationally fixed connection by means of the plug-in shaft unit 1 for supporting the torque of the hub motor 2a on the frame 11.
Fig. 6 and 7 show a further alternative embodiment of the plug-in shaft unit 1. In this case, both the first sub-element 3 and the second sub-element 4 are arranged in sections within a sleeve 7 (not shown in fig. 6 and 7). The retention of the hub 2 on the frame 11 is thus not only achieved by the first sub-element 3 as described above, but by the first sub-element 3 as well as by the second sub-element 4. In this case, the second sub-element 4 can be rotated relative to the frame 11 in order to be able to carry out the assembly on the first sub-element 3. Similar to the examples described above, this fitting can be achieved by tightening the first thread 3a and the second thread 4 a. The torque support is thus effected on one side of the hub 2 in the region of the first subelement 3.
The function of the first sub-element 3 and the second sub-element 4 is otherwise identical to that described previously. In particular, the first sub-element 3 forms a first stop 3b and the second sub-element 4 forms a second stop 4b, in order to achieve a reliable connection of the hub 2 and the frame 11. The contour regions 5, 6a, 6b of the first subelement 3 are not explicitly shown, but are configured similarly to what has been described above, wherein the first subelement 3 in this example has only the second contour regions 6a, 6b.
As is also shown in fig. 6 and 7, a groove-shaped recess 12 is provided in the first sub-element 3 for guiding the line 9. Alternatively, such a recess 12 can also be used in the example of the plug-in shaft unit 1 shown in fig. 2 and 3.
