Hybrid power transmission and automobile

Abstract

The invention discloses a hybrid power transmission which comprises an engine, a clutch, a first motor, a second motor, a gear set, a synchronizer, an input shaft and an output shaft. The clutch is used for combining or cutting off power transmission between the engine and the input shaft; a motor shaft of the first motor is connected with the input shaft or a flywheel output end of the engine through gear transmission; the shift gear set comprises at least two groups of driving gears and driven gears which are meshed with each other, the driving gears are hollowly sleeved on the input shaft, and the driven gears are sleeved on the output shaft; a motor shaft of the second motor is fixedly connected with one of the driving-gear gears through a shaft sleeve which is hollowly sleeved on the input shaft; the synchronizer is used for selectively combining or cutting off power transmission in the direction from the input shaft and the gear gear set to the output shaft. According to the hybrid power transmission, high-efficiency output of the transmission under the conditions of low, medium and high vehicle speeds and various loads is achieved, the structure is simple, and space arrangement is compact.

Description

technical field [0001] The invention relates to the technical field of vehicle transmissions, in particular to a hybrid transmission and an automobile using the hybrid transmission. Background technique [0002] A HEV is a vehicle that uses multiple energy sources, usually a conventional engine (ICE) using liquid fuel and an electric motor using electrical energy to propel the vehicle. Hybrid vehicles can operate in a variety of drive modes, but have limited battery capacity and rely primarily on engine combustion for power. [0003] Existing hybrid schemes exist in dual-motor mode, one of which can only be used to generate electricity or start the engine, and cannot participate in driving with the other motor, and currently due to layout space problems, they are all 1-speed or 2-speed schemes. Moreover, the drive motor can only be arranged off-axis, which makes the transmission efficiency of the system low and the power insufficient. Contents of the invention [0004] T...
