Furthermore, the invention relates to a multi-speed transmission with the arrangement. Furthermore, the invention relates to a bicycle or pedelec with the arrangement.

[0002] A variety of bicycles and pedelecs are known from the state of the art. Pedelecs differ from bicycles in that they feature an electric motor to assist the rider. Derailleur or hub gears are typically used to shift gears. Derailleur gears are particularly maintenance-intensive, and hub gears are particularly complex and heavy.

[0003] DE 690 29 148 T2 discloses a multi-speed hub with a fixed shaft on which a hub body and a drive part rotate, and a planetary gear. The connection between the hub body and the drive part is detachably formed.

[0005] DE 20 2007 016 197 U1 relates to a control ring for a multi-speed hub, which is arranged between a hub sleeve and a ring gear, is rotated by relative movement and thereby disengages the pawls, wherein the control ring is made of plastic and has radially aligned spring sections and axially aligned control fingers.

[0006] US 2011 / 0 009 231 A1 relates to an internally shifted hub comprising a hub axle, a hub shell, a drive element, a planetary gear, and a shifting mechanism. The hub shell rotates freely around the hub axle, and the drive element rotates freely relative to the hub axle and the hub shell. The planetary gear is arranged between the hub shell and the drive element and transmits the rotation of the drive element to the hub shell and the rotation of the hub shell to the drive element. The shifting mechanism selects one of the transmission paths.

[0007] US 2012 / 0 028 751 A1 relates to a shifting mechanism for a transmission, comprising a planetary gear, a shift cam connected to a planetary gear assembly in the planetary gear, a rotatable cable ring with a ramp, a rotatable ramp ring cooperating with the ramp of the cable ring, and a spring connected between the cable ring and the shift cam, wherein the shift cam is rotated by the spring force and the transmission shifts.

[0008] EP 1 958 866 A2 relates to a multi-speed hub gear assembly for bicycles comprising a hub axle, a driver, a hub shell, a power transmission mechanism, a pawl, and a pawl retraction mechanism, wherein the power transmission mechanism transmits rotational power from the driver to the hub shell via two power transmission paths, and the pawl transmits torque between the driver and the hub shell via the first power transmission path, while the pawl retraction mechanism restricts movement of the pawl during torque transmission via the second power transmission path.

[0009] EP 2 008 926 A1 relates to a multi-speed hub gear assembly for bicycles comprising a hub axle, a driver, a hub shell, a power transmission mechanism and a shift control mechanism, wherein the shift control mechanism selects different power transmission paths.

[0010] DE 602 09 410 T2 relates to a bicycle gearshift positioning device comprising a base element, two rotatable bodies, a positioning element, a pawl and a pawl control element, wherein the pawl is moved into the engaged or released position depending on the rotational position of the bodies.

[0011] The present invention is based on the object of specifying an arrangement for actuating a switching element of a multi-stage transmission in planetary design for a bicycle or a pedelec and a multi-stage transmission as well as a bicycle or pedelec, which have a low construction cost and the highest possible operating comfort.

[0012] This object is achieved according to the invention by the features of independent patent claims, wherein advantageous and claimed developments result from the subclaims and the description as well as the drawings.

[0013] Accordingly, an arrangement for actuating at least one shifting element of a planetary multi-speed transmission for a bicycle or pedelec is proposed. In order to minimize installation space requirements and achieve particularly simple and maintenance-friendly actuation of the shifting element, at least one rotatably mounted shifting sleeve or the like is provided, the rotational movement of which can actuate at least one shifting element to be shifted.

[0014] With the proposed actuation, one or more shifting elements are actuated by simply turning the shift sleeve, thus establishing an operative connection between the shifting element and at least one transmission element. This allows a desired gear in the multi-speed transmission to be engaged very easily.

[0015] To achieve a direct operative connection between the shifting element and the transmission component of the multi-speed transmission to be shifted, the shifting sleeve can have at least one circumferentially extending through-opening or the like, through which the operative connection between the shifting element and the transmission component for shifting a desired gear is provided depending on the rotational position of the shifting sleeve achieved by the rotational movement. Due to the direct operative connection, no structurally complex conversions of the generated shifting movement, which reduce shifting comfort, are necessary with the proposed arrangement.

[0016] The fact that the shifting element is positioned radially outside the shift sleeve and the transmission component to be shifted is positioned radially inside the shift sleeve results in a particularly space-saving design, as the shift sleeve to be actuated is particularly easy to reach on the outside. This type of actuation can also be integrated into existing transmissions without any additional design effort.

[0017] The actuation or operating arrangement according to the invention can preferably be used to actuate shifting elements designed as freewheel brakes or the like. This advantageously allows several freewheel brakes arranged axially one behind the other in a multi-speed transmission to be actuated via a common shift sleeve. The fact that the freewheel brakes have an outer ring fixed to the housing and are thus mounted radially on the outside of the multi-speed transmission results in a particularly simple design.

[0018] The switching movement generated by the rotary movement of the switching sleeve can be performed manually or automatically in the proposed arrangement. Manual actuation can be achieved, for example, by a spring-loaded Bowden cable or similar device on the switching sleeve. Automated switching or actuation can be provided, for example, by using an electric or similar drive for the switching sleeve.

[0019] The arrangement according to the invention is used for actuation in a multi-stage transmission as a bottom bracket transmission with multiple planetary gear sets, wherein several freewheel brakes actuated via the shift sleeve and several freewheel clutches are provided to implement the gear stages. This results in the particular advantage that the actuation of the freewheel brakes simultaneously actuates the freewheel clutches, placing them in the overrunning drive state or the locking direction state. Consequently, additional actuations for the freewheel clutches are not required. Furthermore, a space advantage results from the preferred coaxial arrangement of the planetary gear sets of the bottom bracket transmission as a multi-stage transmission relative to the pedal crankshaft.

[0020] A further aspect of the present invention is to provide a multi-stage transmission with the arrangement according to the invention, which results in the above-described and further advantages.

[0021] A next aspect of the present invention is to provide a bicycle or a pedelec with the arrangement according to the invention, which results in the above-described and further advantages.

[0023] The figures show various embodiments of an arrangement for actuating several switching elements designed as freewheel brakes B1, B2, B3, B4 of a multi-stage transmission in planetary design for a bicycle or a pedelec, shown as an example.

[0024] Regardless of the respective design variants, the actuation of the various freewheel brakes B1, B2, B3, B4 is carried out via a rotatably mounted switching sleeve 1, in that the rotational movement of the switching sleeve 1 generates an actuating movement in the associated freewheel brakes B1, B2, B3, B4. The switching sleeve 1 has a plurality of through openings 2, 2A, 3, 3A, 4, 4A, 5, 5A running in the circumferential direction or direction of rotation for each freewheel brake B1, B2, B3, B4 to be actuated. Depending on the rotational position of the switching sleeve 1 achieved by the rotational movement, an operative connection is provided between the respective freewheel brake B1, B2, B3, B4 to be actuated and a transmission component 6, 7, 8, 9 to be actuated by this freewheel brake. The freewheel brakes B1, B2, B3, B4 are arranged radially outside the switching sleeve 1 and the transmission components 6, 7, 8, 9 to be switched are arranged radially inside the switching sleeve 1.The transmission components 6, 7, 8, 9 are connected to gear set elements of the associated planetary gear sets RS1, RS2, RS3, RS4 of the multi-stage transmission in order to realize the desired gear stages.

[0025] Each freewheel brake B1, B2, B3, B4 has an outer ring 11, 12, 13, 14 which is connected in a rotationally fixed manner to a housing 10 of the multi-stage transmission, which outer ring has at least one spring-loaded locking pawl 15, 16, 17, 18 which is pivotably mounted radially inwards and has at least one locking cam 19, 19 A, 20, 21, 22, wherein the respectively associated transmission component 6, 7, 8, 9 has a driving toothing into which the associated locking pawl 15, 16, 17, 18 engages in the switched or closed state of the freewheel brake B1, B2, B3, B4. The locking cams 19, 19A, 20, 21, 22 assigned to the locking pawls 15, 16, 17, 18 serve to move the respective locking pawl 15, 16, 17, 18 into the locked and open states. The respective locking pawl 15, 16, 17, 18 forms a common component pivotable about a pivot axis with the at least one associated locking cam 19, 19A, 20, 21, 22.

[0026] In Fig. 1 shows a section of the arrangement according to the invention for actuating the first freewheel brake B1 of the multi-stage transmission as an example of a first embodiment. In this illustration, the pawl 15 of the first freewheel brake B1 is in the locked state, i.e., the pawl 15 is in engagement with the driving toothing of the associated transmission component 6. As a result, a gear set element of the associated first planetary gear set RS1 of the multi-stage transmission, which gear set element is connected to the transmission component 6, is fixed. Furthermore, Fig. 1 that the switching sleeve 1 is coupled to a Bowden cable 23 and a return spring 24 to carry out a desired rotational movement to reach a predetermined rotational position for switching a predetermined gear stage.

[0027] In the illustrated design variant, the pawls 15, 16, 17, 18 are spring-loaded in the closing direction, and the locking cams 19, 19A, 20, 21, 22 have an opening action, so that the pawls 15, 16, 17, 18 are self-locking. It is also possible for the pawls 15, 16, 17, 18 to be spring-loaded against the closing direction, and the locking cams 19, 19A, 20, 21, 22 to have a closing action.

[0028] In Fig. Figure 2 shows an example of a section of the arrangement according to the invention for actuating the fourth freewheel brake B4 of the multi-speed transmission. In this illustration, the locking pawl 18 of the fourth freewheel brake B4 is in the locked state, i.e., the locking pawl 18 is engaged with the driving teeth of the associated transmission component 9.

[0029] In Fig. 3 is a sectional view along the section line AA according to Fig. 2 by the pawl 18 of the fourth freewheel brake B4 in the locked state. This illustration clearly shows that the pawl 18 is pivotally mounted in a recess 25 on the inside of the outer ring 14 of the fourth freewheel brake B4. In the locked state, the pawl 18 is pivoted radially inward to engage the drive teeth 26 of the associated transmission component 9.

[0033] Fig. 6 shows a further sectional view according to Fig. 5 by the snap ring 27 in the fourth freewheel brake B4 without distance x to the outer ring 14, which corresponds to the locked state of the pawl 18.

[0034] In Fig. 7 is a sectional view along the section line CC according to Fig. 2 is represented by the locking cam 22 of the pawl 18 in the fourth freewheel brake B4. The locking cam 22 is located in front of the through-opening 2A of the switching sleeve 1, so that the pawl 18 is held in the recess 25 of the outer ring 14 by the locking cam 22 located on the outer circumference of the switching sleeve 1. Accordingly, the open state of the pawl 18 is shown.

[0035] In Fig. 8 is another sectional view according to Fig. 7 is shown by the locking cam 22 of the pawl 18 in the fourth freewheel brake B4. In this illustration, the switching sleeve 1 has been rotated further to the right in the drawing plane, so that the locking cam 22 is located in the associated through-opening 2A, whereby the pawl 18 is simultaneously located in the associated through-opening 2 and engages with the driving toothing 26 of the associated transmission component 9. Accordingly, the locked state of the pawl 18 is shown.

[0036] Fig. Figure 9 shows the switching sleeve 1 unfolded into the plane of the drawing to better illustrate the various passages 2, 2A, 3, 3A, 4, 4A, 5, 5A in the circumferential direction as guide or raceways for guiding the pawls 15, 16, 17, 18 and for guiding the locking cams 19, 19A, 20, 21, 22 of the various freewheel brakes B1, B2, B3, B4 to be actuated in the arrangement according to the invention. The passages 2, 2A, 3, 3A, 4, 4A, 5, 5A are provided axially adjacent to one another on the switching sleeve 1.The through openings 2, 2 A, 3, 3 A, 4, 4 A, 5, 5 A shown axially next to one another above the center line are each assigned to a first pawl 15, 16, 17, 18 and the through openings 2, 2 A, 3, 3 A, 4, 4 A, 5, 5 A shown axially next to one another below the center line are assigned to a second pawl 15, 16, 17, 18 (not shown in detail), the two pawls 15, 16, 17, 18 of each freewheel brake B1, B2, B3, B4 being arranged approximately radially opposite one another on the circumferential region of the switching sleeve 1. The center line in . Fig. 9 also forms the axis of rotation of the switching sleeve 1. It is also possible that additional pawls for each freewheel brake B1, B2, B3, B4 are assigned to the circumference of the switching sleeve.

[0037] The switching sleeve 1 shown as an example is for the Fig. 14 to 16, the multi-stage transmission shown as examples is provided, so that the rotation of the shift sleeve 1 actuates the four freewheel brakes B1, B2, B3, B4, in order to engage sixteen gears or gear stages in conjunction with the other four freewheel clutches C1, C2, C3, C4. Accordingly, the individual gears are shown next to the shift sleeve 1 shown in the plane in order to assign the various openings 2, 2A, 3, 3A, 4, 4A, 5, 5A to the various gear stages.

[0038] The two through-openings 2 are assigned to the two pawls 15 and the two through-openings 2A are assigned to the two locking cams 19 of the first freewheel brake B1. As can be seen from the circuit diagram according to Fig. 16, the first freewheel brake B1 for gears 1 to 8 is disengaged or opened, so that the pawls 15 are in their open state. Consequently, no passage openings are assigned to gears 1 to 8. From the shift diagram according to Fig. 16 further shows that the first freewheel brake B1 is closed for gears 9 to 16. Accordingly, the passage openings 2 and 2A are assigned to gears 9 to 16, so that the pawls 15 are moved into their closed or locked state by the locking cams 19.

[0039] The through-openings 3 are assigned to the locking pawls 16 and the through-openings 3A are assigned to the locking cams 20 of the second freewheel brake B2. As can be seen from the circuit diagram according to Fig. 16, the second freewheel brake B2 is disengaged or opened for gears 1 to 4 and 9 to 12. Accordingly, no through-openings are assigned to gears 1 to 4 and 9 to 12. The shift pattern further shows that the second freewheel brake B2 is closed for gears 5 to 8 and 13 to 16. Accordingly, through-openings 3 and 3A are assigned to gears 5 to 8 and 13 to 16.

[0040] The through-openings 4 are assigned to the locking pawls 17 and the through-openings 4A are assigned to the locking cams 21 of the third freewheel brake B3. As can be seen from the circuit diagram according to Fig. 16, the third freewheel brake B3 is disengaged or opened for gears 1 and 2, 5 and 6, 9 and 10, and 13 and 14, respectively. Consequently, no through-openings are assigned to these gears. The shift pattern also shows that the third freewheel brake B3 is closed for gears 3 and 4, 7 and 8, 11 and 12, and 15 and 16. Consequently, the through-openings 4 and 4A are assigned to gears 3 and 4, 7 and 8, 11 and 12, and 15 and 16.

[0041] The through-openings 5 ​​are assigned to the locking pawls 18 and the through-openings 5A are assigned to the locking cams 22 of the fourth freewheel brake B4. As can be seen from the circuit diagram according to Fig. 16, the fourth freewheel brake B4 is disengaged or opened for gears 1, 3, 5, 7, 9, 11, 13, and 15, respectively. Consequently, no through-openings are assigned to these gears. The switching diagram also shows that the fourth freewheel brake B4 is closed for gears 2, 4, 6, 8, 10, 12, 14, and 16. Accordingly, the through-openings 5 ​​and 5A are assigned to gears 2, 4, 6, 8, 10, 12, 14, and 16, so that the locking cams 22 move the pawls 18 into their locking positions accordingly.

[0042] In all freewheel brakes B1, B2, B3, B4, the through-openings 2 A, 3 A, 4 A, 5 A for the associated locking cams 19, 20, 21, 22 are each slightly shorter than the through-openings 2, 3, 4, 5 of the associated pawls 15, 16, 17, 18, since the pawls 15, 16, 17, 18 are slightly longer in the circumferential direction of the outer rings 11, 12, 13, 14 than the locking cams 19, 20, 21, 22, which is particularly evident from the Fig. 7 and Fig. 8 results.

[0043] In Fig. Figure 10 shows an example of a possible gear detent on the shift sleeve 1. Several detent recesses 28 are provided circumferentially on the shift sleeve 1, which are assigned to the corresponding gears. Furthermore, a detent ball 29 is provided, which is preloaded by a detent spring 30 and is positively received in the corresponding detent recesses 28 when the selected gear is set. It is also possible to provide a detent on a shift lever.

In this embodiment, two locking cams 19, 19A are assigned to the locking pawl 15 of the first freewheel brake B1, thereby further improving the support and guidance on the switching sleeve 1. The locking cams 19, 19A are arranged axially on both sides of the locking pawl 15. Accordingly, for this embodiment, two through-openings 2A are provided on both sides of the switching sleeve 1, next to the through-opening 2 for the second locking cam 19A.

[0047] In Fig. 14 is a schematic diagram and in Fig. 15 shows a longitudinal section of the multi-stage transmission as a bottom bracket transmission. The couplings and connections of the individual gear set elements are apparent to the expert at least from the schematic diagram. The corresponding circuit diagram is shown in Fig.16 and represents the states of the freewheel brakes B1, B2, B3, B4 and the freewheel clutches C1, C2, C3, C4 for each gear. The multi-stage planetary transmission has a pedal crankshaft 31 as the transmission input shaft and a transmission output shaft 32 as the output shaft, as well as four planetary gear sets RS1, RS2, RS3, RS4 and the four freewheel brakes B1, B2, B3, B4 as well as the four freewheel clutches C1, C2, C3, C4, whereby 16 gears can be realized. The arrangement according to the invention for actuating the freewheel brakes B1, B2, B3, B4 is used particularly advantageously in the multi-stage transmission shown, whereby the freewheel clutches C1, C2, C3, C4 do not have to be actuated. However, the arrangement can also be used in other operations without any problem.
