VARIABLE-SPEED GEAR ARRANGEMENT FOR A VEHICLE, VEHICLE COMPRISING THE VARIABLE-SPEED GEAR ARRANGEMENT, AND METHOD FOR ASSEMBLING THE VARIABLE-SPEED GEAR ARRANGEMENT

摘要

A variable-speed gear arrangement for a vehicle includes a harmonic drive device, a driven wheel and an optional stop disk. The stop disk can be arranged between the driven wheel and a shaft, with a fastener for connecting the shaft to the stop disk and the driven wheel. The fastener presses the shaft, the stop disk and the driven wheel together in an axial direction. The driven wheel and/or the shaft and/or the stop disk includes a deformation section and the deformation section includes a contact surface and a deformation surfaced. In a first state of assembly, the deformation section brings a member of the clamping connection into contact with the contact surface, simultaneously forming a free deformation region. In a second state of assembly, the contact surface and the deformation surface are applied to the member of the clamping connection in a flat manner.
