Abstract

The invention discloses a double-planetary-row multimode hybrid power vehicle driving system and relates to the technical field of vehicles. The double-planetary-row multimode hybrid power vehicle driving system comprises an engine, a front planetary row, a rear planetary row, a first clutch, a second clutch, a third clutch, an overrun clutch, a brake, a first motor and a second motor; and through joint and separation of a clutch system and the brake, switching of different working modes can be achieved. The double-planetary-row multimode hybrid power vehicle driving system has the characteristics of better technological succession with an existing vehicle, better vehicle power performance, better fuel economy and low emission and has multimode-driving, stepless speed change, parallel-connection and hybrid-connection system functions, the problem that in a low-speed area, the vehicles are poor in acceleration performance and limited in gradeability is solved, the efficient interval of the hybrid power system is increased, development with high performance and low cost is achieved, and scale industrialization is easy to achieve.

Description

technical field

[0001] The invention relates to the technical field of automobiles, in particular to a dual-planetary multi-mode hybrid vehicle drive system. Background technique

[0002] With increasingly stringent vehicle emission regulations and rising fuel prices, more and more industrialized countries have reached a consensus that future cars should have lower carbon dioxide emissions and energy consumption. Hybrid technology effectively solves the shortcomings of traditional internal combustion engine vehicles such as high fuel consumption and poor emissions, and is gradually recognized by the industry. There are three types of drive systems for hybrid vehicles: series, parallel and hybrid. Series hybrid electric vehicles have the advantages of greater freedom in vehicle chassis layout and simple powertrain control, but have the disadvantage of low overall efficiency due to the secondary conversion of energy in the drive system. Parallel hybrid electric vehicle has t...
