Abstract

The invention discloses a power output unit with a power disconnection function and an automobile, and relates to the technical field of automobiles. The power output unit comprises an input shaft, ashaft sleeve, an output shaft and a driving assembly for driving the shaft sleeve to move up and down; the shaft sleeve is arranged on the input shaft, and the shaft sleeve is connected with the output shaft in a transmission mode; and a secondary engaging part is mounted on the input shaft, and a primary engaging part matched with the secondary engaging part is mounted on the shaft sleeve. According to the power output unit, four-wheel drive can be achieved while two-wheel drive is achieved, the requirements of automobile performance are met, the combustion efficiency is ensured, and the automobile fuel consumption is lowered.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a power output unit with a power disconnect function and an automobile. Background technique [0002] Modern vehicles are usually configured with two-wheel drive or all-wheel drive, where power from two-wheel drive is transmitted to the front or rear wheels, and all-wheel drive allows power to be transmitted to all four wheels, while all-wheel drive usually refers to permanent Active engagement or automatic engagement provides power to all four wheels, allowing the vehicle to achieve better performance on rough terrain and / or in adverse weather conditions. [0003] However, although all-wheel drive improves the driving performance of the car, it is usually accompanied by a loss of fuel efficiency. Therefore, in order to balance performance and combustion efficiency, optional all-wheel drive is necessary. Contents of the invention [0004] The purpose of the present inventi...
