Abstract

The invention provides a detachable two-stage power takeoff device which takes off power from a transmission provided with a differential. The detachable two-stage power takeoff device comprises a primary power takeoff unit and a secondary power takeoff unit, wherein the output end of the primary power takeoff unit is coaxially in linkage with the input end of the secondary power takeoff unit, the first power takeoff unit comprises a primary driving rotation member and a primary driven gear which are meshed with each other, and the primary driving rotation member is the differential of the transmission. Compared with the prior art, part quantity is decreased, the size of the power takeoff device is decreased, and accordingly an arrangement space is saved. In addition, a half shaft can be avoided, arrangement can be more flexible, and production cost can be reduced. The detachable two-stage power takeoff device is suitable for various transmissions provided with differentials and used for taking off power from the gear ring positions of the transmissions.

Description

technical field [0001] The invention relates to the technical field of power transmission and output mechanisms, in particular to a two-stage detachable power take-off. Background technique [0002] The power take-off device of the car is generally installed outside the gearbox, and the power is obtained through the differential case of the gearbox. The input shaft of the power take-off device is connected with the differential case of the gearbox, and the input gear is installed on the input shaft. [0003] The current dual-stage power take-off is powered by the differential case, and has many parts and a large volume, which cannot meet the space layout requirements of the vehicle. figure 1 Shown is an existing two-stage power take-off, the first-stage and second-stage power take-off units of the power take-off are both arranged in the power take-off housing, and the interior of the power take-off is composed of two horizontal shafts, a The root longitudinal axis, a pair ...
