Problems solved by technology

[0010] The P1 / P2 position has the same disadvantages: the motor and the engine must be in the same gear at the same time, and the speed ratio cannot be decoupled, which affects the flexibility of their respective load adjustments
However, since the motor is connected to the gear through the output shaft, it does not have the function of power generation at stop
At the same time, the P3 motor generally only has one gear, and the load adjustment flexibility is low.

Abstract

The invention discloses a single-motor single-planet-row multi-gear hybrid power gearbox, a system and a vehicle. A single-planet-row and parallel fixed-shaft gear hybrid structure is adopted, so thatfour engine independent driving modes, one motor independent driving mode, one ECVT mode, five parallel driving modes, five traveling power generation modes and one parking power generation mode canbe achieved just with three shafts, a simple planet row, six parallel fixed shaft gears, four gear shifting elements and a simple clutch device. The gearbox also has following functions: a motor P3 / P1position switching function is achieved, the P3 high efficiency and a P1 parking power generation function are both considered, and meanwhile the risk of a motor hybrid gearbox is avoided through theECVT mode.

Description

technical field [0001] The invention relates to a multi-speed hybrid transmission, which belongs to the technical field of automobile transmissions, in particular to a single-motor single-planetary multi-speed hybrid transmission, a system and a vehicle. Background technique [0002] Single-motor multi-speed hybrid transmissions have been widely used in various vehicles, and there are two main risks: [0003] One is that when the battery power is low, it cannot start running in time. [0004] If a conventional parallel fixed-axis gear structure is used, the driver needs to wait for the engine to generate electricity until the battery power reaches the minimum start-up requirement, and then use the motor to start; or it needs to add a friction-type starting clutch to start directly, which increases the cost of parts and axial dimensions, and friction control. There are also higher demands on drivability and reliability. [0005] If a planetary row structure is adopted, ECVT...
