Automobile reducer with heat-dissipating function

Abstract

The invention relates to the field of automobile reducer equipment, in particular to an automobile reducer with a heat-dissipating function. The automobile reducer comprises a shell, a driving shaft, a driving gear, two half axles and a plurality of reducing gears. A reducing cavity is formed in the shell, a lubricating oil channel is arranged in the shell, the lower end of the lubricating oil channel communicates to the reducing cavity, an oil inlet port is formed in the upper end of the lubricating oil channel, an oil outlet port communicating to the reducing cavity is formed in the lower end of the shell, a water cooling circulating mechanism is also arranged in the shell, a cooling mechanism is arranged on one of the half axles, and an air cooling mechanism matched with the cooling mechanism is arranged on the driving shaft in a sleeving manner. By arranging the water cooling circulating mechanism, the air cooling mechanism and the cooling mechanism to cool the reducer, the heat-dissipating effect of the reducer can be improved effectively as the water cooling circulating mechanism, the air cooling mechanism and the cooling mechanism are matched in work. The energy consumption can be reduced on the premise of guaranteeing heat dissipation of the reducer by selecting the cooling mechanism, the water cooling mechanism and the water cooling circulating mechanism to work.

Description

technical field [0001] The invention relates to the field of automobile reducer equipment, in particular to an automobile reducer with heat dissipation function. Background technique [0002] The main reducer is a kind of automobile reducer, and the main reducer is a mechanism that can change the torque and speed in the drive axle. The basic function is to increase the torque from the transmission or cardan transmission, while reducing the speed and changing the direction of torque transmission. During the use of the automobile reducer, a large amount of heat will be generated due to mechanical movement. If the heat is not dissipated in time, the temperature will be too high to cause the deterioration of the lubricating oil, which will affect the service life of the automobile reducer. [0003] Chinese patent No. CN105202170B discloses a heat dissipation method and device for a vehicle main reducer, which belongs to the technical field of heat dissipation and cooling for au...

Problems solved by technology

When this patent is in use, the heat in the reducer is absorbed by the semiconductor cooling plate and dissipated from the other side. However, there are still the following deficiencies in use. There are many and fast speed, but the volume of the semiconductor cooling chip is limited, which leads to a heavy burden on the semiconductor cooling chip, which will affect the life of the semiconductor cooling chip and cause the equipment to be easily damaged. On the other hand, after working for a period of time, the semiconductor cooling chip will There is no other heat dissipation equipment outside the reducer, which will cause the temperature outside the reducer to rise and approach the temperature inside the reducer. This kind of internal and external temperature difference will seriously affect the working effect of the semiconductor cooling plate
