Abstract

This utility model provides a drive system and a vehicle. The drive system includes a first planetary transmission structure, a second planetary transmission structure, a first brake, a second brake, a third brake, an output transmission component, an engine, an input shaft, a first clutch, and a second clutch. The second planetary carrier is connected to the first planetary carrier via a second sun gear, and the second planetary carrier is connected to the first ring gear. The first brake can brake the first sun gear, and the third brake can brake the second ring gear. One of the first planetary carrier and the first ring gear is connected to the second brake, and the other is connected to the output transmission component. By controlling the first brake, the second brake, the third brake, the first clutch, and the second clutch, the power output of the engine can have at least five transmission paths. When the engine is working, it can switch the power transmission path according to the power demand to achieve maximum operating efficiency.
