Title: VARIABLE-SPEED GEAR ARRANGEMENT FOR A VEHICLE, VEHICLE COMPRISING THE VARIABLE-SPEED GEAR ARRANGEMENT, AND METHOD FOR ASSEMBLING THE VARIABLE-SPEED GEAR ARRANGEMENT
Abstract:
The invention relates to a variable-speed gear arrangement (1) for a vehicle, comprising a harmonic drive device (2), a driven wheel (4) and a stop disk (5), the stop disk (5) being arranged between the driven wheel (4) and the shaft (3), with a fixing means (8) for connecting the shaft (3) to the stop disk (5) and the driven wheel (4), the fixing means (8) pressing the shaft (3), the stop disk (5) and the driven wheel (4) together in the axial direction such that a clamping connection is formed, the driven wheel (4) and/or the shaft (3) and/or the abutment disk (5) comprising a deformation section (7), the deformation section (7) comprising a contact surface (7a) and a deformation surface (7b). In a first state of assembly, the deformation section (7) brings a member of the clamping connection into contact with the contact surface (7a) and the deformation surface (7b) simultaneously forms a free deformation region (7c) in relation to the member of the clamping connection, and in a second state of assembly, the contact surface (7a) and the deformation surface (7b) are applied to the member of the clamping connection in a flat manner.
