Auxiliary transmission, hybrid power assembly device and control method and automobile

Abstract

The invention discloses an auxiliary transmission, a hybrid power assembly device and control method and an automobile. The auxiliary transmission comprises a sun gear, a planet carrier, a planet wheel, a gear ring, a second power input shaft, a power transmission part and a clutch, wherein a driving side of the sun gear is provided with a first power input shaft which is arranged on a first axis;the planet carrier is arranged on a driven side of the sun gear, and the driven side of the planet carrier is provided with a power output shaft; the planet wheel is rotatably arranged on the planetcarrier and is externally meshed with the sun gear; the gear ring is arranged on the driven side of the planet carrier, the inner ring of the gear ring is meshed with the inner part of the planet wheel, the planet wheel is driven by the sun gear to rotate, the planet wheel revolves along the inner ring of the gear ring, and the revolution of the planet wheel drives the planet carrier and the poweroutput shaft to rotate; the second power input shaft is arranged on a second axis; the power transmission part is connected with the second power input shaft and meshed with the outer ring of the gear ring, and the gear ring drives the planetary gear to revolve along the outer ring of the sun gear; the clutch is connected with the gear ring and the power output shaft for separating or engaging the gear ring and the power output shaft.

Description

technical field [0001] The invention relates to an auxiliary transmission, a hybrid power assembly device with the auxiliary transmission, a control method for the hybrid power assembly device and an automobile with the hybrid power assembly device. Background technique [0002] In order to cope with the increasing pressure of environmental protection, energy saving and emission reduction, major international automobile companies are vigorously developing new energy vehicles, and adopt different technologies. At present, new energy vehicles mainly include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles and other new energy vehicles. Among them, since hybrid vehicles have two power sources of "engine" and "electric motor", they not only have smooth acceleration and excellent quietness, but also take into account the characteristics of low fuel consumption and low emissions. Moreover, hybrid vehi...

AI Technical Summary

Problems solved by technology

However, these existing mainstream hybrid electric vehicles have at least the following problems: poor compatibility with existing traditional power systems, unable to transform existing traditional electric vehicles to achieve the purpose of energy saving and emission reduction; high cost, Usually two or more electric motors and a very complex control system are required; it is impossible to reduce the production cost of hybrid electric vehicles by taking advantage of the existing advantages of high reliability and existing investment of traditional electric vehicles
