Vehicle oil temperature heat management system and vehicle

Abstract

The invention discloses a vehicle oil temperature heat management system. The vehicle oil temperature heat management system comprises an engine body, a water pump, a gearbox oil cooler, a thermostat, a first pipeline connecting part and a second pipeline connecting part. A first closed loop is formed through pipeline sequential connection between the engine body, the first pipeline connecting part, the thermostat, the gearbox oil cooler, the second pipeline connecting part and the water pump. The vehicle oil temperature heat management system further comprises a first radiator. A second closed loop is formed through pipeline sequential connection between the engine body, the first pipeline connecting part, the first radiator, the thermostat, the gearbox oil cooler, the second pipeline connecting part and the water pump. Correspondingly, the invention further discloses a vehicle with the above-mentioned vehicle oil temperature heat management system. According to the vehicle oil temperature heat management system, heating and cooling functions of the gearbox oil temperature are integrated; working efficiency of the gearbox can be improved comprehensively; and thus fuel consumption of the whole vehicle is lowered.

Description

technical field [0001] The invention relates to the field of thermal management of automobile gearbox oil, in particular to a vehicle oil thermal management system and a vehicle. Background technique [0002] The gearbox of a car is divided into two types: manual and automatic. The manual gearbox is mainly composed of gears and shafts, and the variable speed and torque are generated through different gear combinations; the automatic gearbox AT is composed of hydraulic torque converter, planetary Composed of a variable pitch system and a hydraulic control system, the variable speed and torque are achieved through hydraulic transmission and gear combination. A car's transmission oil temperature has a great influence on the performance and control of the transmission. [0003] In the prior art, the following two oil cooling systems are mainly used to control the oil temperature of the gearbox: 1. The oil cooling system is used to control the oil temperature of the gearbox by t...

Problems solved by technology

[0003] In the prior art, the following two oil cooling systems are mainly used to control the oil temperature of the gearbox: 1. The oil cooling system is used to control the oil temperature of the gearbox by taking water from the large circulation of the engine (water is taken from the water outlet chamber of the radiator). The disadvantage is that it can only cool the oil temperature of the gearbox, and there is a problem that the oil temperature of the gearbox rises slowly to a reasonable temperature range in winter or in high cold areas, which leads to low efficiency of the gearbox and has a significant impact on fuel consumption; The oil cooling system controls the oil temperature of the gearbox by taking water from the small circulation of the engine (in series with the warm air water tank). Inadequate cooling of the gearbox also results in inefficient gearbox operation
