Active air-cooled lubricating device of gearbox

Abstract

The invention relates to an active air-cooled lubricating device of a gearbox, and belongs to cooling lubricating devices of automobile gearboxes. A gearbox body is communicated with an active air cooling heat dissipation module through a gearbox oil outlet pipe and a gearbox oil inlet pipe so that the gearbox body can be communicated with the active air cooling heat dissipation module in a circulating manner. The active air-cooled lubricating device has the advantages that hydraulic energy still existing in engine oil in the gearbox is utilized, the engine oil is used for driving a hydraulicmotor, then a cooling fan is driven to conduct active air cooling, and compared with pure natural air cooling, the cooling effect is greatly improved, energy is saved, and energy losses are reduced; and the engine oil is controlled, lubricated and cooled in the gearbox body, the oil amount is sufficient, normal work in the gearbox is guaranteed, a heating module is arranged at an oil outlet pipe of an oil pool in the gearbox and used for heating the engine oil during starting and preheating the engine oil in the gearbox of an automobile, the automobile can be rapidly started during starting, and oil consumption is reduced.

Description

technical field [0001] The invention belongs to a cooling and lubricating device for a gearbox of an automobile, in particular to a cooling and lubricating device for a gearbox that utilizes the hydraulic energy of the gearbox oil to perform active air cooling. Background technique [0002] The development of automobiles has a long history. With the rapid development of the automobile industry and the improvement of people's living standards, automobiles have become an indispensable tool in people's daily life, and people's requirements for automobiles are getting higher and higher. The cooling and lubrication of the oil is a key technology in the design of the gearbox, which affects the long-term use and reliability of the gearbox unit. Since automatic transmission vehicles do not need to manually switch gears while driving, and are easy to operate, automatic transmission vehicles are becoming more and more popular among consumers. Therefore, many cars are equipped with aut...
