To engage a seventh gear, the first, second, and third brakes are engaged and the fourth brake is released, with the first, second, and third one-way clutches in the overrunning drive state and the fourth one-way clutch in the locking direction state.

[0018] In the proposed multi-speed transmission with a maximum of 14 gears, up to three brakes must be released and one brake engaged simultaneously when shifting to the next higher or lower gear, or up to three brakes must be engaged and one brake engaged simultaneously. In contrast, in the proposed multi-speed transmission with a maximum of 13 gears, a maximum of only two instead of three brakes must be released and one brake engaged simultaneously when shifting to the next higher or lower gear, or a maximum of only two instead of three brakes must be engaged and one brake engaged simultaneously, which improves shifting quality.

[0019] A preferred embodiment of the invention can provide that the individual gear sets are each designed as a minus planetary gear set, resulting in a particularly space-efficient arrangement. It is also conceivable for one or more of the individual gear sets to be designed as plus planetary gear sets. A minus planetary gear set can preferably be converted into a plus planetary gear set if the planet gear carrier and ring gear connections on this gear set are swapped and the amount of the stationary gear ratio is increased by 1. A minus planetary gear set has rotatably mounted planet gears on its planet gear carrier, which mesh with the sun gear and the ring gear of this planetary gear set, so that when the planet gear carrier is held stationary and the sun gear is rotating, the ring gear rotates in the opposite direction to the sun gear rotation direction.A plus planetary gear set has inner and outer planetary gears that are rotatably mounted on its planetary gear carrier and mesh with one another, with the sun gear of this planetary gear set meshing with the inner planetary gears and the ring gear of this planetary gear set meshing with the outer planetary gears, so that the ring gear rotates in the same direction of rotation as the sun gear when the planetary gear carrier is held stationary and the sun gear is rotating.

[0020] In a preferred embodiment of the multi-stage transmission, it is provided that a transmission input shaft is connected to a planetary gear carrier of a first planetary gear set, that a sun gear of the first planetary gear set is connected to a planetary gear carrier of a second planetary gear set, that a ring gear of the first planetary gear set is connectable to a ring gear of the second planetary gear set via a second one-way clutch, that the ring gear of the first planetary gear set is connected to a planetary gear carrier of a third planetary gear set, that a sun gear of the second planetary gear set is lockable via a first brake, that the sun gear of the second planetary gear set is connectable to the transmission input shaft via a first one-way clutch, that the ring gear of the second planetary gear set is lockable via a second brake, that a sun gear of the third planetary gear set is lockable via a third brake,that the sun gear of the third planetary gear set is connectable via a third one-way clutch to a ring gear of the third planetary gear set and to a planet gear carrier of a fourth planetary gear set, that a sun gear of the fourth planetary gear set is connected to a transmission output shaft, that a ring gear of the fourth planetary gear set is lockable via a fourth brake, and that the ring gear of the fourth planetary gear set is connectable to the transmission output shaft via a fourth one-way clutch.

[0021] Furthermore, for the preferred embodiment of the multi-stage transmission, regardless of the various gear designs, it is proposed that the first planetary gear set has a stationary ratio of approximately -1.50, that the second planetary gear set has a stationary ratio of approximately -1.555 and that the third planetary gear set has a stationary ratio of approximately -1.50.

[0022] For the multi-stage transmission with a maximum of 14 gears, it is suggested that the fourth planetary gear set has a stationary ratio of approximately -2.295.

[0023] In this way, a particularly efficient multi-stage transmission with a maximum of 14 gears with a total transmission spread of approximately 920% with gear steps of approximately 18% to 19%, preferably 18.6%, is made possible.

[0024] Furthermore, by omitting the last and / or the penultimate gear and / or the second-to-last gear, it is possible to realize at least one 11-speed version, at least one 12-speed version, and at least one 13-speed version. The 11-speed version has a total transmission spread of approximately 550%, while the 12-speed version has a total transmission spread of approximately 650%, and the 13-speed version has a total transmission spread of approximately 770%.

[0025] For the multi-stage transmission with a maximum of 13 gears, it is proposed that the fourth planetary gear set has a stationary ratio of approximately -1.778.

[0026] In this way, a particularly efficient multi-stage transmission with a maximum of 13 gears with a total transmission spread of approximately 770% is also possible with gear steps of approximately 18% to 19%, preferably 18.6%.

[0027] Furthermore, by omitting the last and / or penultimate gear, it is possible to realize at least one 11-speed version and at least one 12-speed version. The 11-speed version has a total gear ratio spread of approximately 550%, while the 12-speed version has a total gear ratio spread of approximately 650%.

[0028] Alternatively, the multi-stage transmission with a maximum of 13 gears can preferably be equipped with four planetary gear sets with the same stationary ratios of, for example, -1.62 for cost-effective simplification, which leads to a total transmission spread of approximately 685% with gear steps on average of approximately 17.5%.

[0029] In order to enable electrical assistance in addition to muscle power drive by the driver, the multi-stage transmission according to the invention can be provided with at least one electric machine or the like. The electric machine can be connected, for example, to the transmission input shaft, the transmission output shaft and / or to other shafts of the transmission directly or via one or more gear stages, chains, toothed belts or the like. A switching element such as a freewheel clutch or the like can also be used for this purpose. This has the advantage that when the electric motor is switched off, no drag torque occurs during pedaling and the electric motor is switched off. If the connection is via a gear stage, for example, a gear ratio can be achieved, for example to slow down.

[0030] The object underlying the invention is also achieved by a bicycle, for example a pedelec, e-bike or the like, with the multi-stage transmission described above, whereby the advantages already described and further advantages arise.

[0031] The present invention is further explained below with reference to the drawings. They show:

[0042] Figure 12 is a shift diagram of a third 14-speed version of the multi-speed transmission; and Figure 13 is a shift diagram of a fourth 14-speed version of the multi-speed transmission.

[0043] Figure 1 illustrates a possible gear set design of a multi-speed transmission according to the invention, exemplified as a bottom bracket transmission in a coaxial design using a bicycle 3. Figures 2 to 13 show various 13-speed and 14-speed versions with the associated gear ratios i and the gear steps phi, as well as the overall transmission spread phiGes. The bicycle 3 is designed as a pedelec.

[0044] In the circuit diagrams according to Figures 2 to 13, the individual states of the switching elements designed as brakes B1, B2, B3, B4 and the one-way clutches F1, F2, F3, F4 are indicated, whereby for the brakes B1, B2, B3, B4 an empty box indicates the open or deactivated state and a cross or an X indicates the closed state, whereas for the one-way clutches F1, F2, F3, F4 an empty box indicates the overrunning drive state and a cross or X indicates the blocking direction state. The overrunning operation or overrunning drive state of a one-way clutch F1, F2, F3, F4 means that the freewheel is not locking and therefore is not transmitting any torque. A one-way clutch F1, F2, F3, F4 can be in an overrunning drive if one of the elements connected to the freewheel is rotating so fast that the freewheel cannot lock.The locking direction state of a freewheel clutch F1, F2, F3, F4 means that the freewheel is locked and thus transmits a torque.

The multi-stage transmission comprises a transmission input shaft 1 as the drive, which in Figure 1 is designed, for example, as a pedal crankshaft, and a transmission output shaft 2 as the output, which can be designed, for example, as a chainring or a sprocket or toothed belt wheel.

[0047] In detail, the bottom bracket transmission is provided with the following: the transmission input shaft 1 is connected to a planetary gear carrier PT1 of a first planetary gear set RS1, a sun gear SR1 of the first planetary gear set RS1 is connected to a planetary gear carrier PT2 of a second planetary gear set RS2, a ring gear HR1 of the first planetary gear set RS1 is connectable to a ring gear HR2 of the second planetary gear set RS2 via a second one-way clutch F2, the ring gear HR1 of the first planetary gear set RS1 is connected to a planetary gear carrier PT3 of a third planetary gear set RS3, a sun gear SR2 of the second planetary gear set RS2 is lockable via a first brake B1, the sun gear SR2 of the second planetary gear set RS2 is connectable to the transmission input shaft 1 via a first one-way clutch F1, and the ring gear HR2 of the second planetary gear set RS2 is lockable via a second brake B2.that a sun gear SR3 of the third planetary gear set RS3 can be locked via a third brake B3, that the sun gear SR3 of the third planetary gear set RS3 can be connected via a third one-way clutch F3 to a ring gear HR3 of the third planetary gear set RS3 and to a planet gear carrier PT4 of a fourth planetary gear set RS4, that a sun gear SR4 of the fourth planetary gear set RS4 is connected to the transmission output shaft 2, that a ring gear HR4 of the fourth planetary gear set RS4 can be locked via a fourth brake B4, and that the ring gear HR4 of the fourth planetary gear set RS4 can be connected to the transmission output shaft 2 via a fourth one-way clutch F4.
