Title:
TWO-GEAR TRANSMISSION FOR AN ELECTRICALLY DRIVEABLE MOTOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/210898
Kind Code:
A8
Abstract:
A two-gear transmission (10) for an electrically driveable motor vehicle, in particular an electric motor scooter, is provided with an input shaft (12) for the introduction of a torque, an output shaft (18) for the output of the torque, a first gear stage (14), a second gear stage (16), a slider sleeve (28) which is guided on the input shaft (12) or on the output shaft (18) in an non-rotatable but axially displaceable manner, for the establishment of a positively locking connection to a first gearwheel (20) of the first gear stage (14) and/or to a second gearwheel (24) of the second gear stage (16), and an actuating actuator (40) which has an extendable actuating finger (38) for the axial movement of the slider sleeve (28), wherein the slider sleeve (28) has a sliding ramp (42, 44) which runs in the circumferential direction and is bevelled with respect to a radial plane for the output at the extended actuating finger (38) of the actuating actuator (40). Shifting of the two-gear transmission (10) can take place very rapidly with the aid of the slider sleeve (28) as a result of the actuating finger (38) which can slide on the sliding ramp (42, 44), with the result that a comfortable power transmission is made possible in the case of an electrically driveable motor vehicle.
