Problems solved by technology

The existing hybrid transmissions improved on the basis of mechanical automatic transmissions all have the following defects: 1) the motor cannot be disengaged when the vehicle is driven by the pure engine, which reduces the overall efficiency of the transmission; The large inertia of the synchronous motor rotor leads to long synchronization time and difficulty in gearing; 3) It is impossible to use only one motor to realize parking and charging, etc.

Abstract

The invention discloses an improved type synchronous mechanism and a hybrid power transmission thereof. The synchronous mechanism comprises a charging gear engagement tooth, an EV gear driving gear, acharging gear synchronous ring, a motor transmission gear, a synchronous gear sleeve, an EV gear engagement tooth and an EV gear synchronous ring; the charging gear engagement tooth and the EV gear driving gear are oppositely arranged, the charging gear synchronous ring, the motor transmission gear and the synchronous gear sleeve are sequentially connected to the charging gear engagement tooth ina sleeving manner, and the EV gear engagement tooth and the EV gear synchronous ring are sequentially connected to the EV gear driving gear in a sleeving manner. On the basis of an original mechanical automatic transmission structure, a driving motor is connected in ingeniously; a synchronous mechanism controls the transmission direction of motor power, engine power and motor power can be independently controlled in the transmission process, mutual interference is avoided, and meanwhile, in the needing process, mutual compensating is achieved.

Description

technical field [0001] The invention relates to a technology in the field of hybrid electric vehicles, in particular to an improved synchronizing mechanism and a transmission for hybrid electric vehicles. Background technique [0002] The design principle, production process and technology of manual transmission have been mature and stable for a long time. The addition of motor power can make up for the loss of engine power during the shifting process of mechanical automatic transmission, and can make full use of the high efficiency and low cost of manual transmission. The advantage is the solution of choice for many hybrid models. The existing hybrid transmissions improved on the basis of mechanical automatic transmissions all have one of the following defects: 1) the motor cannot be disengaged when the vehicle is driven by a pure engine, which reduces the overall efficiency of the transmission; 2) the synchronizer needs to be in gear The large inertia of the rotor of the ...
