Problems solved by technology

[0004] The purpose of the present invention is to provide a power-split hybrid power transmission in order to overcome the above-mentioned defects in the prior art. Using a single planetary row can effectively reduce the number of planetary rows in the existing power-split hybrid transmission scheme. The structure and connection of the transmission are relatively complicated, and at the same time, the advantages of the input power split of the single planetary row are fully utilized to fully adjust the operating point of the engine to achieve better fuel economy of the vehicle at different speeds

Abstract

The invention relates to a power distributional hybrid power speed changer which is respectively connected with an engine, and odd number or even number of motors. The power distributional hybrid power speed changer comprises a single planet row, a gear shifting element and a common gear, wherein the single planet row comprises a sun wheel, an outer gear ring, a planet wheel and a planet carrier;the planet wheel is respectively meshed with the outer gear ring and the sun wheel; the single planet row is provided with two rotation freedom degrees; the rotating speeds of the components can be determined through the two rotation freedom degrees; the gear shifting element comprises two clutches; the common gear has a single rotation freedom degree; the rotating speeds of the components can bedirectly or indirectly determined through the single planet row freedom degree. Compared with the prior art, the power distributional hybrid power speed changer provided by the invention has the advantages of low mechanical complexity, low cost, low control difficulty and the like.

Description

technical field [0001] The invention relates to the drive field of electromechanical hybrid vehicles, in particular to a power-split hybrid transmission. Background technique [0002] Electromechanical hybrid vehicles typically involve the use of an internal combustion engine and one or more electric motor / generators. Existing hybrid transmission schemes can basically be divided into two categories: hybrid schemes composed of one or two electric motors added to traditional transmissions and hybrid schemes specially designed for From the point of view of the existing development trend, the transmission scheme mainly includes the hybrid transmission scheme with series-parallel connection as the main driving mode and the power split hybrid transmission scheme with planetary row as the main drive mode. The hybrid transmission scheme with series-parallel connection as the main driving mode is relatively simple in structure, low in research and development costs, and generally ha...
