Problems solved by technology

However, pure electric vehicles in new energy vehicles have problems that are difficult to solve in the short term, such as high vehicle cost, long charging time, and unstable battery life. It has the advantages of both electric vehicles and pure electric vehicles, and has a variety of efficient driving modes, which can be driven by the engine and the first motor at the same time, and can also be driven by the engine or the first motor alone
[0003] At present, hybrid vehicles usually use one engine and one motor to provide driving force, with few gear options, poor adaptability, inability to start the engine while driving, poor fuel-saving effect, and even the power is easily interrupted when changing gears. The driving experience is not good, and it is easy to cause accidents
There are also some hybrid vehicles that use one engine and two motors, and the two motors are arranged in parallel, which requires a large space and poor layout

Abstract

The invention provides a multi-mode hybrid drive system. A input shaft, an intermediate shaft, a first transmission shaft and a second transmission shaft are arranged in parallel, one end of the input shaft is connected with the crankshaft output end of an engine through a clutch, the clutch is arranged in a rotor of a second motor, an outer hub of the clutch is fixedly connected with the rotor of the second motor, the crankshaft output end of the engine is fixedly connected with the outer hub of the clutch in the circumferential direction, a driving friction disc of the clutch is fixedly connected with the outer hub, a driven friction disc of the clutch is fixedly connected with the input shaft, a third transmission assembly is arranged on the first transmission shaft, a fourth transmission assembly is arranged on the second transmission shaft, the third transmission assembly matches the fourth transmission assembly, the third transmission assembly further matches the first motor, and the fourth transmission assembly further matches a differential mechanism. The multi-mode hybrid drive system has the characteristics that the structure is simple, and the driving system tends to be miniaturized.

Description

technical field [0001] The invention relates to the field of hybrid electric vehicles, in particular to a multi-mode hybrid electric drive system. Background technique [0002] Traditional fuel vehicles usually use petroleum as an energy source. With the shortage of resources and the environmental pollution caused by vehicle exhaust emissions, the country's restrictions on vehicle exhaust emissions are becoming more and more stringent. New energy vehicles with low emissions and low fuel consumption. However, pure electric vehicles in new energy vehicles have problems that are difficult to solve in the short term, such as high vehicle cost, long charging time, and unstable battery life. It has the advantages of both the pure electric vehicle and a variety of efficient driving modes, which can be driven by the engine and the first electric motor simultaneously, and can also be driven by the engine or the first electric motor alone. [0003] At present, hybrid vehicles usuall...
