Abstract

The invention provides a dynamic coupling device cooling and lubricating system of a hybrid electric vehicle. The system comprises a dynamic coupling device external cooling circulatory system and a dynamic coupling device shell internal cooling lubricating circulatory system. The dynamic coupling device external cooling circulatory system comprises an oil pan on the lower portion of a dynamic coupling device shell, an oil inlet, an oil outlet, a radiator and a power oil pump, wherein the oil inlet and the oil outlet are formed in the bottom of the oil pan, the inlet end of the radiator is connected with the oil outlet, one end of the power oil pump is connected with the outlet end of the radiator, the other end of the power oil pump is connected with one end of an oil pipe, and the oil pipe penetrates through the oil inlet in the bottom of the oil pan, extends into the dynamic coupling device shell and is communicated with the dynamic coupling device shell internal cooling lubricating circulatory system. The dynamic coupling device cooling and lubricating system integrates conveying, storing, cooling and filtering, the space size and the weight of the system are reduced, and the defects that the structure is complex, the size is large and cost is high after an existing dynamic coupling device cooling and lubricating system is separated can be overcome.

Description

Technical field [0001] The invention relates to a cooling and lubricating system for a power coupling device of a hybrid vehicle. Background technique [0002] With the increasingly prominent global environmental and energy issues, the development of new vehicles with low emissions and low fuel consumption has become the primary task of today's automotive industry. The development and application of hybrid electric vehicle technology avoids the shortcomings of pure electric vehicles in battery technology and energy infrastructure. It is a good solution to current problems and has become a hot spot in international automotive research and development today. In foreign countries, the research and development of hybrid electric vehicles has gone through more than ten years, but the mature and industrialized companies are Toyota and Honda; in China, from government, scientific research institutions, universities and colleges to automobile companies Both began to pay attention to and...
