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

The invention discloses a power driving system and a vehicle with the power driving system. The power driving system comprises a dynamic coupling device, a power transmission unit, a power source, a first motor generator, a second motor generator and a first brake device. The dynamic device comprises a first sun wheel, a first planet carrier, a first gear ring, a second sun wheel, a second planet carrier and a second gear ring. The power transmission unit is coaxially in linkage with the first sun wheel and the second sun wheel. The power source is set to selectively joint the power transmission unit. The first motor generator is in linkage with the first gear ring. The second motor generator is in linkage with the second gear ring. The first brake device is used for braking the power transmission unit directly or indirectly. According to the power driving system, the differential function is realized on the basis of omitting a conventional mechanical differential mechanism. The power driving system is rich in transmission mode.

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...
