Speed reducer with transfer device and parking mechanism

Abstract

The invention belongs to the technical field of speed reducers, and particularly discloses a speed reducer integrating a transfer device and a parking mechanism, the speed reducer comprises a speed reducer body and a gear shifting and parking device, and the gear shifting and parking device is installed on an output shaft assembly of the speed reducer body; the gear-shifting parking device comprises a gear-shifting motor, a gear-shifting gear sleeve, a parking gear sleeve, a connecting gear sleeve, a gear-shifting shifting finger assembly and a gear-shifting shifting fork assembly. The connecting gear sleeve is fixed on the output shaft assembly, the gear shifting motor and the parking gear sleeve are fixed in a shell of the speed reducer body, the gear shifting gear sleeve is located between the parking gear sleeve and the connecting gear sleeve, and the gear shifting gear sleeve can axially move on the output shaft assembly and can rotate along with the output shaft assembly; the gear shifting poking finger assembly comprises a gear shifting rod, a first gear shifting assembly, a second gear shifting assembly and a gear withdrawing poking finger. The parking mechanism and the 2 / 4 drive switching structure use the same gear shifting motor, and the same gear shifting parking device is used for completing switching between a parking mode and a driving mode.
