Plug-in multi-gears hybrid transmission

Abstract

The invention discloses a plug-in multi-gears hybrid transmission comprising a planetary gear set for adjusting a power transfer path, a motor integrating functions such as startup, drive, power generation and the like, a first output system, a second output system, a battery system and a power distribution and electronic control system. The plug-in multi-gears hybrid transmission also includes a gear ring, a planet carrier and a sun gear arranged in the planetary gear set, a torsional damper arranged between an engine and the gear ring, a clutch K1 arranged between the engine and the gear ring and used for controlling connection or separation between the engine and a transmission, a brake B1 arranged between the gear ring and a transmission case, and a clutch K2 arranged between the gear ring and the sun gear in the planetary gear set and for controlling fixation or rotation between the gear ring and the sun gear. The plug-in multi-gears hybrid transmission has the characteristics that 1, the unique transmission structure is adopted, and the low-speed starting performance of the plug-in multi-gears hybrid transmission is much higher than that of ordinary transmissions, so that the plug-in multi-gears hybrid transmission has extremely high dynamic property; 2, multiple gears are arranged; and the engine and the motor are always in the best economic working state; 3, accelerating and gear-shifting are realized by the stepless speed regulation; the power is not interrupted; and extremely high shifting efficiency and gear-shifting ride comfort are realized.

Description

technical field [0001] The invention belongs to the field of automobile transmissions, in particular to hybrid transmissions for new energy vehicles. Background technique [0002] The transmission is the most important transmission part in the power transmission system, especially in the car, the performance of the transmission directly determines the performance of the car, determines the transmission efficiency of the car, determines the fuel economy of the car, and determines the smooth shifting of the car sex and comfort. The plug-in hybrid electric vehicle transmission refers to the transmission system installed on a plug-in hybrid electric vehicle that can be equipped with two power sources at the same time - a thermal power source (generated by a traditional gasoline engine or a diesel engine) and an electric power source (battery). . By using motor drive, engine drive, and hybrid drive on hybrid vehicles, the power system can be flexibly adjusted according to the a...

Problems solved by technology

[0003] Although there are many inventions of hybrid transmission technology at home and abroad, and these inventions have achieved obvious technological progress and economic effects, their structure should have shortcomings. The power loss of the first motor doing useless work; another example is that in Honda's i-MMD system, the engine is only suitable for direct drive when cruising at high speed, and the other working conditions are to drive the generator to generate electricity, so there is a loss of mechanical energy converted to electrical energy, and the battery is charged. loss, loss of battery discharge, loss of electrical energy to mechanical energy
