Problems solved by technology

[0003] A typical hybrid structure consists of an engine, a generator, an electric motor, and a planetary gear mechanism. The planetary gear mechanism is used as a power coupling and distribution device to provide vehicles with two drive modes: pure electric and hybrid drive. There is a problem with this structure : Vehicle reversing only relies on pure electric operation, limited by the state of charge of the battery, and the reversing mileage is limited

Abstract

The invention discloses a hybrid power drive device which comprises an engine, a generator, a front planet gear mechanism, a brake, a rear planet gear mechanism, a motor, two inverters, a battery and a controller, wherein gear rings of the front planet gear mechanism and the rear planet gear mechanism are integrated; a planet carrier of the front planet gear mechanism is connected with an output shaft of the engine and a sun gear is connected with a rotor of the generator; a sub gear of the rear planet gear mechanism is connected with a rotor of the motor and a planet carrier is connected with a power output shaft; the brake of an integral gear ring of the front planet gear mechanism and the rear planet gear mechanism can be realized by controlling the brake; the battery is respectively connected with the generator and the motor through the inverters, and the controller controls the engine and the brake. The invention realizes two hybrid power drive modes of series connection and parallel connection by using one mechanism, achieves the purposes of saving energy and reducing emission, and can increase backing travelled distance by a series connection working mode when a car is backed.

Description

technical field [0001] The invention relates to a hybrid power device, in particular to a hybrid power driving device. Background technique [0002] At present, gasoline-electric hybrid vehicles are usually divided into three structural types: series, parallel and hybrid. The arrangement of the series structure is simple, but the transmission efficiency is too low; the transmission efficiency of the parallel structure is high, but the working speed of the engine cannot be adjusted. The hybrid structure overcomes the shortcomings of series and parallel, and has better overall performance. [0003] A typical hybrid structure consists of an engine, a generator, an electric motor, and a planetary gear mechanism. The planetary gear mechanism is used as a power coupling and distribution device to provide vehicles with two drive modes: pure electric and hybrid drive. There is a problem with this structure : Vehicle reversing only relies on pure electric operation, limited by the ...
