Problems solved by technology

[0003] However, the above-mentioned transmission device is suitable for working vehicles (such as snow removal vehicles), and its motor output mechanism is a worm gear mechanism, which realizes the unidirectionality of the power transmission of the motor through self-locking, and only acts on the steering differential when the vehicle is cornering. It cannot realize the working conditions of pure electric, hybrid and parking power generation

Abstract

Provided are a power drive system (1000) and a vehicle (10000); the power drive system (1000) comprises: a power coupling device (100), said power coupling device (100) comprising: a first sun gear (11), first planetary carrier (14), and first ring gear (13), and a second sun gear (21), second planetary carrier (24), and second ring gear (23); the first ring gear (13) and second ring gear (23) are coaxially connected; an intermediate shaft (61), said intermediate shaft (61) being configured to move concomitantly with the first ring gear (13) and second ring gear (23); an engine (54), said engine (54) being configured to selectably engage with the intermediate shaft (61); a first electric motor generator (51), second electric motor generator (52), and third electric motor generator (53); the first electric motor generator (51) moves concomitantly with the first sun gear (11), the second electric motor generator (52) moves concomitantly with the second sun gear (21), and the third electric motor generator (53) is configured to selectably move concomitantly with the engine (54); a first braking device (41) which directly or indirectly brakes the intermediate shaft (61). The power drive system (1000) achieves a differential function in a situation without a conventional mechanical differential, and also has an abundance of drive modes.

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...
