Description

technical field

[0001] The invention relates to the field of automobile manufacturing, in particular to a series-parallel hybrid transmission. Background technique

[0002] Hybrid technology can better reduce fuel consumption and emissions, and it also continues the traditional vehicle technology well. The technical threshold is relatively low, and the motor control technology is becoming more and more mature. There are many implementation forms of hybrid electric vehicles, and the most common ones on the market are parallel hybrid systems and hybrid hybrid systems. The parallel hybrid system is based on the conventional transmission, adding one or two power motors to transmit power to the vehicle axle in parallel, usually equipped with a charging device to form a plug-in hybrid transmission.

[0003] Parallel hybrid transmissions can be divided into different configurations such as P0, P1, P2, P2.5, P3, and P4 according to the position of the power motor or the coupling el...
