[0017] In the proposed multi-speed transmission with up to 14 gears, when shifting to the next higher or previous lower gear, up to three brakes must be simultaneously opened and one brake engaged, or up to three brakes must be simultaneously engaged and one brake opened. In contrast, in the proposed multi-speed transmission with up to 13 gears, when shifting to the next higher or previous lower gear, only a maximum of two brakes must be simultaneously opened and one brake engaged, or only two brakes must be simultaneously engaged and one brake opened, instead of three, which improves the shifting quality.

[0018] A preferred embodiment of the present invention can provide that each wheel set is respectively implemented as a negative planetary gear set, thereby obtaining a particularly advantageous arrangement in terms of structural space. It is also conceivable that one or more wheel sets in each wheel set are implemented as a positive planetary gear set.

[0019] By swapping the planet carrier connection and the ring gear connection on the negative planetary gear set and increasing the fixed-axis transmission ratio by 1, the gear set can be preferably transformed into a positive planetary gear set. The negative planetary gear set has rotatably mounted planetary gears on its planet carrier. These planetary gears mesh with the sun gear and the ring gear of the planetary gear set, so that when the planet carrier is stationary and the sun gear rotates, the ring gear rotates in a direction opposite to the direction of rotation of the sun gear. The positive planetary gear set has rotatably mounted inner and outer planetary gears on its planet carrier, which are in toothed engagement with each other. The sun gear of the planetary gear set meshes with the inner planet gears, and the ring gear of the planetary gear set meshes with the outer planet gears, so that when the planet carrier is stationary and the sun gear rotates, the ring gear rotates in the same direction of rotation as the sun gear.

[0020] In a preferred design scheme of the multi-stage transmission, it is provided that the transmission input shaft is connected to the planetary carrier of the first planetary gear set, the sun gear of the first planetary gear set is connected to the planetary carrier of the second planetary gear set, the ring gear of the first planetary gear set can be connected to the ring gear of the second planetary gear set via a second overrunning clutch, the ring gear of the first planetary gear set is connected to the planetary carrier of the third planetary gear set, the sun gear of the second planetary gear set can be fixed via a first brake, the sun gear of the second planetary gear set can be connected to the transmission input shaft via the first overrunning clutch, the ring gear of the second planetary gear set can be fixed via the second brake, the sun gear of the third planetary gear set can be fixed via the third brake, the sun gear of the third planetary gear set can be connected to the ring gear of the third planetary gear set and the planetary carrier of the fourth planetary gear set via the third overrunning clutch, the sun gear of the fourth planetary gear set is connected to the transmission output shaft, the ring gear of the fourth planetary gear set can be fixed via the fourth brake, and the ring gear of the fourth planetary gear set can be connected to the transmission output shaft via the fourth overrunning clutch.

[0021] In addition, for this preferred design of the multi-stage transmission, regardless of the gear implementation scheme adopted, it is proposed that the first planetary gear set has a fixed shaft transmission ratio of approximately -1.50, the second planetary gear set has a fixed shaft transmission ratio of approximately -1.555, and the third planetary gear set has a fixed shaft transmission ratio of approximately -1.50.

[0022] In multi-speed transmissions with up to 14 gears, it is provided that the fourth planetary gear set has a fixed transmission ratio of approximately −2.295.

[0023] In this way, a particularly efficient multi-speed transmission can be realized, which has up to 14 gears and a total transmission ratio range of approximately 920%, wherein the gear ratio ratio is approximately 18% to 19%, preferably 18.6%.

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

[0025] In multi-speed transmissions with up to 13 gears, it is provided that the fourth planetary gear set has a fixed transmission ratio of approximately −1.778.

[0026] In this way, a particularly efficient multi-speed transmission can be realized, which has up to 13 gears and a total transmission ratio range of approximately 770%, wherein the gear ratio ratio is approximately 18% to 19%, preferably 18.6%.

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

[0028] Alternatively, for cost-effective simplification, a multi-speed transmission with up to 13 gears is equipped with four planetary gear sets with the same fixed axis transmission ratio, for example -1.62, which results in a total transmission ratio range of approximately 685% and an average gear ratio of approximately 17.5%.

[0029] In order to be able to achieve electric auxiliary power in addition to being driven by the rider's muscle power, it can be provided in the multi-stage transmission according to the present invention that at least one electric motor or similar device is provided. The electric motor can be connected to the transmission input shaft, transmission output shaft and / or other shafts of the transmission, for example, directly or via one or more transmission stages, chains, toothed belts or similar devices. For this purpose, switching elements such as overrunning clutches or similar devices can also be used if necessary. The advantage obtained thereby is that no drag torque is generated by driving the electric motor by pedaling during pedaling when the motor drive is turned off. When connected, for example, via a transmission stage, it is possible to achieve a transmission ratio that, for example, reduces speed.

[0030] The object of the present invention is also achieved by a bicycle, such as a pedelec, an electric bicycle or the like, which has an above-described multi-speed transmission, wherein the advantages already described and further are achieved. BRIEF DESCRIPTION OF THE DRAWINGS

The overrunning operation or overrunning transmission state of the overrunning clutches F1, F2, F3, F4 means that the overrunning mechanism is not blocked and therefore does not transmit torque.
