Abstract

The invention discloses a transmission case shell with a pressure relief function. The transmission case shell comprises a shell main body, a pressure relief valve, air induction components, cooling components and a ventilation duct, wherein the shell main body is used for mounting a transmission part; the ventilation duct is buried in the bottom of the shell main body and the side walls, where output shafts are located, of the shell main body; the pressure relief valve is mounted at the top of the shell main body; each air induction component comprises an air induction fan, a transmission sealing component and a transmission component; the transmission and sealing components are mounted in the side walls, wherein the output shafts are rotatably mounted, of the shell main body; the air induction fans are mounted in air inlets; and the transmission components are rotatably mounted at the outer sides of the side walls, wherein the output shafts are rotatably mounted. The transmission case shell is simple in structure, and is capable of discharging high-pressure air in the transmission case to prevent the air pressure in the transmission case from being too high, and emitting the heatin the shell main body through the cooling components so as to greatly reduce the temperature in the shell main body, prolong the service life of a transmission mechanism and improving the using quality of the transmission mechanism.

Description

technical field [0001] The invention belongs to the technical field of vehicle components, and in particular relates to a transmission case housing with a pressure relief function. Background technique [0002] The transmission box is a box-shaped part that supports and contains various transmission mechanisms. It is widely used because of its functions of sealing, dustproof, heat insulation, sound insulation, lubricating oil storage and protection. However, the general transmission box has poor heat dissipation effect. It will shorten the service life of the internal parts of the gearbox. [0003] The transmission mechanism in the transmission box is smeared with lubricating oil. After running in the transmission box for a long time, it will not only generate a lot of heat, but also generate more gas, which will increase the air pressure in the transmission box. The pressure difference between the inside and outside of the transmission box is large, and the internal tempera...
