Problems solved by technology

[0003] When the engine is cold started, the temperature of the transmission oil is very low, the viscosity of the oil is too high, and the lubrication effect of the transmission is poor; with the operation of the automatic transmission, a certain amount of power loss will be converted into heat energy, making the oil of the transmission temperature rise
If the oil temperature reaches a certain level, the performance of the lubricating oil will change, the viscosity will decrease, the aging and deterioration will be accelerated, and some components will be carbonized. Damage to the meshing tooth surface or bearing surface will cause equipment failure and have a great impact on the life of the gearbox

Abstract

The invention discloses a heating and cooling system applied to an automatic gearbox and an operation method thereof. The system comprises a temperature-controlled reversing valve, a gearbox cooler, aheat exchanger and a pipeline of the heat exchanger, wherein the temperature-controlled reversing valve is provided with an inlet and two outlets, and the heat exchanger is provided with two sets ofinlets and outlets correspondingly communicating with each other; and the inlet of the temperature-controlled reversing valve is connected with the gearbox, the outlet I of the temperature-controlledreversing valve is connected with the inlet of the gearbox cooler, the outlet II of the temperature-controlled reversing valve is connected with the inlet II of the heat exchanger, the outlet II of the heat exchanger is connected with the gearbox, the inlet II of the heat exchanger is also connected with the outlet of the gearbox cooler, and the inlet I and the outlet II of the heat exchanger areboth connected with an engine. The problems that when the oil temperature of the gearbox is low, the lubricating effect is poor, and when the oil temperature rises to a certain extent, the lubricatingoil film is damaged, the lubricating effect is lost, and the service life of the gearbox is influenced are solved.

Description

technical field [0001] The invention relates to the technical field of thermal management of a powertrain of a passenger car, in particular to a temperature raising and cooling system applied to an automatic transmission and an operating method thereof. Background technique [0002] The automatic transmission is composed of a hydraulic torque converter, gears, and hydraulic control system, and achieves variable speed and torque through the combination of hydraulic transmission and gears. In order to achieve high-quality variable speed and torque, the temperature of the transmission oil is very important. [0003] When the engine is cold started, the temperature of the transmission oil is very low, the viscosity of the oil is too high, and the lubrication effect of the transmission is poor; with the operation of the automatic transmission, a certain amount of power loss will be converted into heat energy, making the oil of the transmission The temperature rises. If the oil ...
