Abstract

The invention provides a two-gear hybrid gearbox and a gear shifting method thereof. The two-gear hybrid gearbox comprises an input shaft, and a first-gear drive gear, a second-gear drive gear, a second clutch and a first clutch are sequentially arranged on the input shaft from left to right; the first-gear drive gear is fixedly connected with the input shaft; the second-gear drive gear is rotatably connected with the input shaft; and an inner ring of the second clutch is fixedly connected with the input shaft. The gear shifting method of the two-gear hybrid gearbox comprises the steps that 11, an engine does not work, and a driving motor works; 12, the first clutch is opened, the second clutch is opened, and a one-way clutch is locked; 13, the driving motor transmits the torque to the input shaft; and 14, the torque is transmitted to an intermediate shaft from the input shaft through transmission connection between the first-gear drive gear and the second-gear drive gear. According tothe two-gear hybrid gearbox and the gear shifting method thereof, two-gear driving of engine driving is achieved, and power is not interrupted in the gear shifting process.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle drive systems, in particular to a two-speed hybrid transmission and a gear shifting method thereof. Background technique [0002] At present, the existing hybrid transmission in the Chinese market is basically a parallel structure, and the P2.5 configuration is not high in technical content. It only adds a motor to the ordinary transmission, and the layout is difficult. [0003] The main reasons for the poor driving effect of the hybrid system are: [0004] 1. The engine drive has only one gear, resulting in high engine speed at high speeds, poor noise and fuel consumption; [0005] Two, although the engine has two gears, power interruption is required for gear shifting. Contents of the invention [0006] One of the objectives of the present invention is to provide a two-speed hybrid gearbox, which realizes two-speed drive driven by the engine, and the power is not interrupted when ...
