Abstract

The invention discloses a power driving system and a vehicle. The power driving system comprises a power coupling device, an immediate shaft, an engine, a first electric power generator, a second electric power generator, a third electric power generator and a first brake device, wherein the power coupling device comprises a first sun gear, a first planet carrier, a first gear ring, a second sun gear, a second planet carrier and a second gear ring, wherein the first gear ring is coaxially connected with the second gear ring; the immediate shaft is arranged to be linked with the first gear ring and the second gear ring; the engine is arranged to be selectively jointed with the immediate shaft; the first electric power generator is linked with the first sun gear; the second electric power generator is linked with the second sun gear; the third electric power generator is arranged to be selectively linked with the engine; and the first brake device is used for directly or indirectly braking the immediate shaft. The power driving system has the advantages that a differential function is realized on the premise of eliminating the traditional mechanical differential mechanism and rich transmission modes are also realized.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a power drive system and a vehicle with the power drive system. Background technique [0002] In a related technology known to the inventor about a transmission device for a vehicle, the transmission device is provided with a pair of differential mechanisms and a pair of motors, and the differential mechanism has a sun gear, a planetary gear, a planetary carrier and an inner ring gear. The engine is input to the sun gears of a pair of differential mechanisms after being shifted by the intermediate transmission structure. The pair of motors respectively input driving forces to the ring gears of the pair of differential mechanisms. The transmission device cancels the traditional mechanical differential element, and uses two sets of planetary gear mechanisms to realize the power coupling of the two motors and the engine. [0003] However, the above-mentioned transmission devic...
