Automatic gearbox cooling system and four-way pipe used for same

Abstract

The invention provides an automatic gearbox cooling system and a four-way pipe used for the system, which are used for reducing the difficulty and cost for developing a whole car cooling system. The automatic gearbox cooling system comprises an oil cooler which is mounted on a shell of an automatic gearbox, wherein a water inlet pipe and a water outlet pipe are arranged on the oil cooler; the water inlet pipe and the water outlet pipe of the oil cooler are connected to the water inlet pipe between a radiator and an engine water pump in a car engine cooling system through the four-way pipe; the four-way pipe provided by the invention comprises a main pipe, a first side pipe and a second side pipe; a cut-off device is arranged in the main pipe of the four-way pipe; the cut-off device is composed of a baffle plate and one or more than one overflow hole on the baffle plate; and the cut-off device is positioned between the first side pipe and the second side pipe. The four-way pipe provided by the invention is used for solving the problem of an original complex pipeline. The four-way pipe has simple structure and is conveniently arranged. Other parts in the car engine cooling system are free from being influenced by the four-way pipe, thereby increasing the universal rate of parts and reducing the difficulty and cost for developing the whole car cooling system.

Description

technical field [0001] The invention belongs to the technical field of automobile cooling systems, and in particular relates to an automatic transmission cooling system and a four-way water pipe applied to the system. Background technique [0002] In order to meet the needs of different customers, generally a model is equipped with both a manual transmission and an automatic transmission. However, the working principle of the automatic transmission is very different from that of the manual transmission. A large number of operating mechanisms of the automatic transmission are driven by the hydraulic system, and its calorific value is much greater than that of the manual transmission. Therefore, in order to ensure the reliability of the automatic transmission, the automatic The gearbox is equipped with a gearbox oil cooler to cool the oil inside the gearbox to ensure that the oil temperature of the gearbox is within a suitable temperature range. [0003] The oil cooler has a ...

AI Technical Summary

Problems solved by technology

Because the gearbox, water pump, and thermostat are respectively located at both ends of the engine, the water pipe of the oil cooler must bypass the engine in the above connection method, which will cause complicated pipeline connections, crowded engine compartment layout of the vehicle, and cooling system. The use rate of components is extremely low, a large number of pipelines need to be developed, and even the thermostat seat of the engine has to be redeveloped, which greatly increases the difficulty and cost of development
