Description

technical field

[0001] The invention belongs to the field of mechanical manufacturing, and in particular relates to a leakage detection and plugging assembly and a plugging method for an oil passage hole of a gearbox body of a power shift tractor. Background technique

[0002] The gearbox is one of the key components of the tractor. It forms the drive train with the rear axle, power take-off shaft transmission, four-wheel drive, brakes and other components. Its function is to convert the high speed and low torque output by the diesel engine into the drive axle and power Low speed and high torque of the output shaft. The tractor gearbox has developed from the initial manual shift mechanical gearbox and synchronous sleeve shift gearbox to today's power shift gearbox. enhanced. The power shift gearbox is mainly composed of three parts: mechanical transmission system, hydraulic control system and electronic control system. The tractor power shift gearbox is a mechanism that us...
