Abstract

The invention discloses a vehicle main reducer heat dissipation method and a device thereof, and belongs to the technical field of heat dissipation and cooling of automobile reducers. The method comprises the steps of arranging an oil cooler immersed in gear lubricant in a main reducer; circulating cooling water subjected to cooling by an engine radiator in the oil cooler; realizing a cooling of the main reducer by heat exchange of the external gear lubricant of the oil cooler with the cooling water inside the oil cooler. According to the method and the device, under the condition that a vehicle original layout structure and an installation environment are not changed, the operating temperature of the lubricant inside an assembly is optimized, the service life of the assembly is improved, and the reliability of the vehicle is further enhanced. Meanwhile, the service condition of the full vehicle is broadened, such as the severe operating conditions of large load and high environment temperature, and the method and the device are very high in universality and practicability.

Description

Technical field [0001] The invention relates to a heat dissipation method and device for a vehicle main reducer, belonging to the technical field of heat dissipation and cooling of automobile reducers, and in particular to a water cooling method and a device for the main reducer. Background technique [0002] At present, military off-road vehicles, especially vehicles with a load-bearing body, have a low vehicle height and poor ventilation and heat dissipation conditions for each assembly of the chassis in order to improve the performance of protection and passing, especially under heavy load and low speed conditions. When the transmission power of the main reducer is large, the internal gear lubricating oil temperature is too high, up to 200 ℃, the heat dissipation of the main reducer housing itself cannot meet the cooling demand, and eventually the lubricating oil becomes invalid and deteriorated due to excessive oil temperature. Early failure of internal parts. In order to so...
