Embodiment Construction

[0117] figure 1 is a schematic diagram of a drive unit 10 for a vehicle such as a bicycle F. FIG. The drive unit 10 is integrated in the bicycle frame 12 in the region of the bottom bracket. In this case, the drive unit 10 can be integrated in the bicycle frame 12 in such a way that the drive unit 10 forms a bottom bracket.

[0118] The drive unit 10 has a housing 14 connected at its outer periphery to a seat tube and a down tube (main pipe) of the bicycle frame 12 .

[0119] In the housing 14 is accommodated a transmission 16 configured to convert the drive motion introduced into the transmission 16 via the crank 18 into chain rings or pulleys having a number of different suitable transmission or gear ratios 20 spins.

[0120] Also accommodated in the housing 14 is an electric motor 22 which can supply additional drive power to the transmission.

[0121] Bicycle F is thus configured as an electric bicycle or pedelec. Preferably, the electric motor 22 can only be controll...

Abstract

The invention relates to a transmission (16) for a vehicle (F), in particular for a vehicle that can be driven by means of muscle force, such as a bicycle (F), having an input shaft (50), having a countershaft (30), having an output shaft (36) that can be connected to a drive wheel (20) of the vehicle (F), having a plurality of switchable first gear sets (R1-R4), having a machine gear (40), the first gear sets (R1-R4) connect the input shaft (50) and the countershaft (30) and are each associated with at least one gear stage, the machine gear (40) is connected or can be connected to one of the shafts, and a drive torque (TM) of the electric machine (22) can be introduced into the machine gear (40). In this case, the first gear set (R1-R4) forms a first partial transmission (32) and a second partial transmission (34), at least one switchable second gear set (R5-R7) connecting the countershaft (30) and the output shaft (36), the at least one second gear set (R5-R7) being associated with at least one gear stage, and the at least one gear stage being associated with the output shaft (36). The machine gear (40) is arranged in the axial direction between the first partial transmission (32) and the second partial transmission (34).

Description

technical field [0001] The present invention relates to a transmission for a vehicle, in particular a vehicle capable of being driven by muscular power, such as a bicycle, having an input shaft, a countershaft, an output capable of being connected to the drive wheels of the vehicle Shaft, having a plurality of switchable first gear sets and having machine gears, the first gear sets connecting the input shaft and the countershaft and being respectively associated with at least one gear stage, the machine gears being connected or connectable to one of the shafts And the driving torque of the electric motor can be introduced into the gears of the machine. [0002] Furthermore, the invention relates to a drive unit for a vehicle, in particular a vehicle such as a bicycle, capable of being driven by muscular power, having a transmission of the type described above and having a machine gear connected to the transmission motor. [0003] The invention also relates to a method for op...
