Abstract

The invention discloses a double clutch planetary 48V electric drive system of a hybrid electric vehicle and relates to the technical field of vehicles. The double clutch planetary 48V electric drive system of the hybrid electric vehicle comprises a front planetary row, a rear planetary row, double clutches, a 48V motor and a box. The front planetary row comprises a power input shaft, a front row sun gear, a front row planet carrier and a public gear ring; the rear planetary row comprises an intermediate driving shaft, a rear row sun gear, a rear row planet carrier and the public gear ring; the double clutches are composed of a low-speed clutch and a high-speed clutch; switching among different working modes can be realized through the connection and separation of the low-speed clutch and the high-speed clutch; and a 48V motor output shaft is connected with the power input shaft. The double clutch planetary 48V electric drive system of the hybrid electric vehicle is compact in structure design, the acceleration performance and climbing ability of the vehicle at a low speed are effectively improved, the motor is miniaturized, the vehicle noise is decreased, and the comprehensive operation efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a 48V electric drive system of a double-clutch planetary hybrid electric vehicle. 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 hybrid drive systems, series, parallel, and hybrid, but these three types have disadvantages such as complex configuration, large changes to the traditional engine powertrain, and high power requirements for the motor. The 48V electric drive system is applied to micro-hybrid and mild-hybrid vehicles. As a low-cost and f...
