Abstract

The invention relates to the technical field of gearboxes, and discloses a temperature control system capable of raising and lowering the temperature of gearbox oil. The system comprises a gearbox unit, an oil cooler temperature control unit, a gearbox temperature control device and a heat exchanger temperature control unit; the gearbox unit is connected with the heat exchanger temperature controlunit through the gearbox temperature control device to form a temperature raising passage, the gearbox unit is connected with the oil cooler temperature control unit through the gearbox temperature control device to form a temperature lowering passage, the gearbox temperature control device controls the switch-on degree of a temperature control valve in the gearbox temperature control device according to the temperature of the gearbox oil flowing through the gearbox temperature control device, and therefore the flow of the temperature raising passage and the flow of the temperature lowering passage are controlled to raise or lower the temperature of the gearbox oil. The temperature control system capable of raising and lowering the temperature of the gearbox oil integrates the dual functions of temperature raising and cooling so that the gearbox oil can be quickly heated to a suitable temperature during cold starting, when the temperature is too high, temperature raising is stopped, and the gearbox oil enters a cooling circulation process.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to a temperature control system capable of raising and lowering the oil temperature of a gearbox. 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 conversion, the temperature of the transmission oil is very important. It has been proved by experience that the optimum working temperature of the transmission oil is around 100°C. [0003] When the engine is cold started, the temperature of the gearbox oil is very low, the viscosity of the oil is too high, and the lubrication effect of the gearbox is poor; on the other hand, as the running time of the automatic gearbox increases, the automatic gearbox oil will gradually accumulate heat The...
