Abstract

The invention discloses a hybrid power device provided with an engine buffer lock mechanism. The hybrid power device comprises an engine, a buffer and lock combination mechanism, a first generator / motor, a first row of planetary gear mechanism, a second row of planetary gear mechanism, a second generator / motor, a first shaft and a second shaft; the buffer and lock combination mechanism is used for locking and buffering the engine; an engine flywheel is connected with the first shaft via the buffer and lock combination mechanism; the first shaft is connected with a planetary carrier of the first row of planetary gear mechanism; and a rotor of the second generator / motor is connected with the second first row of planetary gear mechanism. According to the invention, the engine is locked via the lock mechanism and two generators / motors are used for a dual-motor drive mode when a car is in a pure electric mode, so that the dynamic property of the car is improved. In the invention, two motors are respectively located in two separate shells and then integrally assembled; and meanwhile, the tooth rings of the planetary gear mechanisms are floated so that the planetary gear mechanisms can realize the self-aligning function.

Description

technical field [0001] The invention relates to a hybrid power device, in particular to a hybrid power device with an engine locking mechanism and a driving method thereof. Background technique [0002] Generally, hybrid drive devices for automobiles are divided into three structural types: series, parallel and hybrid. The series structure is gradually eliminated due to the low transmission efficiency. The advantage of the parallel structure is high transmission efficiency, but the disadvantage is that it cannot adjust the working speed of the engine itself. The hybrid structure overcomes the shortcomings of parallel connection and has better overall performance. [0003] A typical hybrid structure consists of an engine, a generator, an electric motor, and an ordinary planetary gear mechanism. The planetary gear mechanism is used as a power coupling and distribution device to provide vehicles with two driving modes: pure electric drive and hybrid drive. However, this syste...
