Abstract

The invention relates to the technical field of electric drive vehicles or unmanned vehicles, in particular to a single-motor power split coupling transmission system applied to electric vehicles or unmanned vehicles. The structure of the single-motor power-splitting coupled transmission system is simple, and it uses a single motor to realize the vehicle's speed change, which meets the requirements of the vehicle's multi-working conditions for power output; it uses a single motor to avoid idle motors under certain working conditions The situation; its hydraulic clutch is in the current state of linkage, which ensures the reliable combination of high-speed transmission lines, and can choose the same model of the same series, thus enhancing the versatility of system parts; it avoids the problem of power interruption in the shift gap existing in ordinary gearboxes; It uses the differential as the speed coupling device, which can borrow mature components from the automotive industry to reduce costs and improve system reliability; in the specific implementation process, the hydraulic circuit of the electronically controlled hydraulic valve can also be combined with the lubricating oil circuit function of the entire system , which is further conducive to the improvement of system integration.

Description

technical field [0001] The invention relates to the technical field of electric drive vehicles or unmanned vehicles, in particular to a single-motor power split coupling transmission system applied to electric vehicles or unmanned vehicles, which uses single-motor power split and then coupled to achieve speed change. Background technique [0002] Electric vehicles have the advantages of zero emissions during driving, diversified and efficient energy utilization, and convenient realization of intelligence, making them one of the focuses of new vehicle research and development. At present, more and more electric drive technology is used in civilian cars, buses, especially unmanned vehicles. [0003] At present, the electric drive device of a vehicle generally adopts a combination of a motor and a gearbox or a motor drive unit directly drives the wheels. [0004] The gearbox can adjust the output torque and speed of the motor through different gears to meet the requirements of...
