Abstract

The invention discloses a twin-motor two-planet-row and single clutch 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; the front planet row is provided with a front planet row planet wheel and a front planet row sun gear; the back planet row is provided with a back planet row planet wheel and a back planet row sun gear; the front planet row and the back planet row share a gear ring. The output shaft of an engine is connected with the input end of an integrated starter generator; the output end of the integrated starter generator is connected with the driving disk of the clutch; the driven disk of the clutch is connected with the planet wheel of the front planet row through a planet carrier; the sun gear of the front planet row is connected with a drive motor; 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 also connected with the drive motor; the outside gear of the gear ring is normally engaged with a power take-off gear. The twin-motor two-planet-row and single clutch 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 drive device in the field of mechanical technology, in particular to a drive device with dual motors, double planetary rows and single clutch 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 dri...
