The invention relates to the technical field of lubricating oil for a gearbox with a DHT structure, in particular to a lubricating oil composition for a gearbox with a DHT structure and application thereof.
Background
In recent years, with the increasing shortage of petroleum resources and the increasing of ecological environment pressure, new energy automobile technology is rapidly developed. In the aspect of power selection of new energy automobiles, hybrid electric vehicles, pure electric vehicles and hydrogen fuel cell vehicles are mainly used at present. The Hybrid Electric Vehicle (HEV) generally refers to a Hybrid Electric Vehicle (HEV), i.e., a conventional internal combustion engine (a diesel engine or a gasoline engine) and an Electric motor are used as power sources, and some engines are modified to use other alternative fuels, such as compressed natural gas, propane and ethanol fuel.
A Dedicated Hybrid Transmission (DHT) is an important component of a Hybrid vehicle, and the DHT is an automatic Transmission system with an electric motor formed by integrating one or more electric motors into a Transmission, and can realize a Hybrid drive function after an engine input is added. In order to realize the whole functions, the motor in the hybrid power system is an indispensable component, and the transmission cannot normally work after the motor is removed.
In order to make the transmission compact, minimize power consumption, reduce component wear, and cool friction pairs, DHTs typically use an "integrated" lubrication scheme for the motor and mechanical transmission, along with a clutch configuration. Compared with the traditional gearbox, the motor is added in the DHT gearbox system, and lubricating oil is required to have excellent electrochemical performance, thermal protection performance under extreme conditions, good compatibility with non-metallic materials such as enameled wires and the like. Therefore, the development of lubricating oil which has excellent electrochemical performance, motor compatibility and clutch anti-wear and anti-friction effects and is used for a gearbox with a DHT structure is of great significance.
