Abstract

The invention discloses a two-planet-row electromechanical coupling driving device of a hybrid vehicle in the technical field of machinery. The device is provided with a front planet row and a back planet row; each of the two planet rows is provided with a planet wheel, a sun gear and a row gear ring; the two planet row gear rings are connected with each other by a clutch. An engine is connected with the planet wheel of the front planet row; an ISG motor is connected with the sun gear of the front planet row; the gear ring of the front planet row is connected with the driving disk of the clutch; the driven disk of the clutch is connected with the gear ring of the back planet row; the planet carrier of the planet wheel of the back planet row is arranged fixedly on a car frame; the sun gear of the back planet row is connected with a drive motor; the outside gear of the gear ring of the back planet row is normally engaged with a power take-off gear. The two-planet-row electromechanical coupling driving device of the hybrid vehicle has the advantages of compact structure, large transmission ratio, large load support capability, stable driving, and high transmission efficiency, thereby realizing power dividing and infinite variable speed at the same time.

Description

technical field [0001] The invention relates to a driving device in the field of mechanical technology, in particular to a dual planetary row electromechanical coupling driving device for a hybrid electric vehicle. Background technique [0002] With the tension of world energy and the strengthening of human environmental awareness, safety, energy saving and environmental protection have become the themes of today's automobile development. As one of the new energy vehicles, hybrid vehicles can better solve the above problems. A hybrid vehicle is a vehicle that is jointly driven by an engine and an electric motor system. The engine can be an internal combustion engine using multiple fuels; the motor can be either a permanent magnet motor or an excitation motor, a synchronous motor or an asynchronous motor. The structure of hybrid electric vehicle (HEV) is mainly divided into parallel type, series type and hybrid type. The hybrid form and the increase of electric drive progr...
