Abstract

The invention relates to a transmission main shell. The transmission main shell comprises a shell body, and a first control oil path controlling a first clutch to perform action, a second control oil path controlling a second clutch to perform action, a third control oil circuit for controlling a third clutch to perform action, a fourth control oil path for controlling a fourth clutch to perform action, and a fifth control oil path controlling a first brake to perform action are formed on the shell; a first lubricating oil path for lubricating the first clutch, a second lubricating oil path for lubricating the second clutch, a third lubricating oil path for lubricating the third clutch, a fourth lubricating oil path for lubricating the fourth clutch and a fifth lubricating oil path for lubricating the first brake are formed on the shell; all the lubricating oil paths and the control oil paths are arranged in the shell, oil pipes do not need to be laid, the structure of a transmission is effectively simplified, and the fault occurrence probability is reduced.

Description

technical field [0001] The invention relates to a gearbox main casing. Background technique [0002] During the working process of the gearbox, it is necessary to supply high-pressure oil to the internal clutch and brake to control the action of the clutch and brake. In the prior art, a through hole is usually opened on the casing of the gearbox, and the oil pipeline is laid in the through hole. , and extend into the gearbox, so as to deliver high-pressure oil to the corresponding position. In the manufacture of this type of oil supply gearbox, in addition to opening a through hole on the main casing, it is also necessary to lay oil delivery pipes, which not only makes the manufacturing process of the gearbox more cumbersome, but more importantly, it also makes the structure of the gearbox more complicated. Complexity increases the chances of failure. [0003] The role of the transmission lubrication system is to provide lubricating oil to the rolling or sliding parts of t...
