Abstract

A power system cooling device comprises a first oil pump, a main pressure regulating valve, a cooling flow control device and a second oil pump. The output end of the first oil pump is connected withthe input end of the main pressure regulating valve, the feedback end of the main pressure regulating valve and the actuator connecting port, the cooling output end of the main pressure regulating valve is connected with the input end of the cooling flow control device, and the oil return output end is connected with an oil recovery device connecting port; the output end of a cooling flow controldevice and the output end of the second oil pump are connected with the input end of the oil cooler interface, the cooling flow control device controls the flow passing through the cooling flow control device, and the output end of the oil cooler interface is connected with a motor cooling channel. When the first oil pump or the second oil pump is used respectively, the above devices all can meetthe cooling requirement of the motor common working conditions (continuous power / rated power output), and when the two oil pumps are used simultaneously, the cooling requirement that the motor outputswith the peak power can be met.

Description

technical field [0001] The present application relates to oil cooling technology, in particular to a power system cooling device. Background technique [0002] With the increasing requirements of market regulations on fuel consumption, more and more hybrid models appear in the market, and will become the mainstream energy-saving technology for a long time in the future. In the hybrid technology, the hybrid transmission occupies the core position, and the current mainstream technology is divided into single-motor type and dual-motor type. Among them, due to the many dual-motor drive modes and complex working conditions, the control requirements for cooling flow also become complicated. The oil cooling method has a high degree of integration, and can take into account the execution functions of mode switching and gear switching. The dual-motor type mostly adopts the oil cooling method. [0003] In the existing oil cooling scheme using dual oil pump drive mode, the flow contr...
