Abstract

The invention provides a power coupling device used for a hybrid electric vehicle and the hybrid electric vehicle. The power coupling device used for the hybrid electric vehicle comprises a one-way clutch assembly, a brake unit, a lock-up clutch unit, a single-row planetary gear train and a shell. The single-row planetary gear train comprises a sun wheel, a planet wheel, a planet carrier and a gear ring. An engine rotation shaft of the hybrid electric vehicle is connected to the sun wheel. The one-way clutch assembly is connected to the sun wheel to prevent the sun wheel from rotating reversely. The brake unit is connected to the sun wheel in order to conduct brake control over the sun wheel. A motor of the hybrid electric vehicle is connected with the gear ring in a matched mode. The planet carrier is connected with a rotation shaft of a speed changer. The lock-up clutch unit is connected with the planet carrier and the gear ring. The power coupling device used for the hybrid electric vehicle controls a power transmission switch by innovatively arranging a clutch and a brake, innovates the arrangement structure of a piston of the clutch, greatly improves the utilization rate of energy, achieves multi-mode operation of the hybrid electric vehicle with a more compact structure, promotes the development of the hybrid electric vehicle, and has wide market prospects.

Description

technical field [0001] The invention belongs to the technical field of automobile structural components, and in particular relates to a power coupling device for a hybrid electric vehicle and the hybrid electric vehicle. Background technique [0002] As a means of transportation, automobiles play a very important role in modern industrial society. With the continuous increase of car ownership and people's increasing demand for automatic transmission cars and hybrid cars, the application of new power transmission mechanisms is becoming more and more extensive. In the domestic auto market and the mainstream auto markets in Europe, America, Japan and South Korea, more and more models have added automatic transmissions such as continuously variable transmission CVT and planetary automatic transmission AT on the basis of the original configuration of only manual transmissions. Configuration. In this way, more and more models need to be matched with special power transmission me...
