Lubricating system for input shaft assembly of automobile transmission

Abstract

The invention provides a lubricating system of an automobile transmission input shaft assembly. The lubricating system is good in lubricating effect. The lubricating system comprises a pressurized oil stirring device (2) which is located in an oil storage cavity (3-1) and assembled on an input shaft (6); the pressurized oil stirring device (2) comprises a pressure cavity (2-1), an oil way (2-2), a pressurizing cavity (2-3) and an oil stirring part (2-4); the inner end of the pressure cavity (2-1) is communicated with a radial oil inlet (6-1) in the input shaft (6), and the side wall of the pressure cavity (2-1) is connected with one end of the oil way (2-2); the other end of the oil way (2-2) is connected with one side of the pressurizing cavity (2-3), and the other side of the pressurizing cavity (2-3) is communicated with an oil storage cavity (3-1); and the oil stirring part (2-4) is located in the pressurizing cavity (2-3) and assembled on the input shaft (6).

Description

technical field [0001] The invention relates to a lubricating system of an automobile transmission, in particular to a lubricating system for an input shaft assembly of an automobile transmission. Background technique [0002] At present, a common lubricating system for the input shaft assembly of an automobile transmission on the market includes a lubricating system formed by the inner cavity surface of the box body 3, the outer circumference of the input shaft 6 and the collar 8, the right end surface of the oil seal 1, and the left end surface of the sealed bearing 4. The oil storage chamber 3-1, the input shaft 6 is provided with an axial oil inlet hole 6-2 and a radial inlet port that communicates with the axial oil inlet hole 6-2 at one end and communicates with the oil storage chamber 3-1 at the other end. The oil hole 6-1, and the radial oil outlet hole 6-3 whose one end communicates with the axial oil inlet hole 6-2, and the other end communicates with the inner cav...

[0002] At present, a common lubricating system for the input shaft assembly of an automobile transmission on the market includes a lubricating system formed by the inner cavity surface of the box body 3, the outer circumference of the input shaft 6 and the collar 8, the right end surface of the oil seal 1, and the left end surface of the sealed bearing 4. The oil storage chamber 3-1, the input shaft 6 is provided with an axial oil inlet hole 6-2 and a radial inlet port that communicates with the axial oil inlet hole 6-2 at one end and communicates with the oil storage chamber 3-1 at the other end. The oil hole 6-1, and the radial oil outlet hole 6-3 whose one end communicates with the axial oil inlet hole 6-2, and the other end communicates with the inner cavity of the box body 3, and one end provided on the box body 3 communicates with the oil storage The tank oil channel 3-2 connected with the cavity 3-1, the oil tank oil channel 5-1 with one end communicated with the other end of the tank oil channel 3-2, and the other end communicated with the inner cavity of the tank body 3 Oil guide 5, said oil guide 5 is connected on the box body 3, its defect is; affected by the centrifugal force generated by the rotation of the input shaft 6, the lubricating oil in the oil storage chamber 3-1 will flow along The radially outward flow of the input shaft 6 cannot flow radially inwardly and enters the radial oil inlet hole 6-1, then flows into the axial oil inlet hole 6-2 from the radial oil inlet hole 6-1 and flows from the radial direction The oil outlet hole 6-3 enters the inner cavity of the box body 3 to lubricate the input shaft assembly assembled in the inner cavity of the box body 3, resulting in poor lubrication of the transmission input shaft assembly and a low service life
