Problems solved by technology

However, the viscosity state and working temperature of the gearbox lubricating oil cannot be changed due to the overall working conditions of the gearbox, and the gearbox cannot be filled with lubricating oil. The lubricating oil can only submerge a small part of the gear, and the shafting lubrication depends on splashing. lubricating oil, it is impossible to change the engagement damping state of the driven wheel of the gear set

Abstract

The invention discloses a transmission gear set that can suppress knocking noise. It includes a driving wheel, a driven wheel engaged with the driving wheel and an output shaft that cooperates with the driven wheel. The driven wheel is loosely sleeved on the output shaft. The driven wheel includes a gear and a sleeve fixed in the gear. The sleeve is made of permanent magnet material and is magnetized. The output shaft is made of ferromagnetic material. The driven wheel of the present invention is made of permanent magnet material. The composite structure formed by the bushing and gear, and the magnetic field effect between the permanent magnet bushing and the output shaft, can not only make the driven wheel rotate normally without wear, but also provide electromagnetic damping to increase the drag torque of the driven wheel, thereby increasing the drag torque of the driven wheel. The meshing rotation damping of the driven wheel keeps the driven wheel and the driving wheel in single-sided contact, reducing or even eliminating the knocking phenomenon caused by the fluctuation of the driving wheel speed.

Description

technical field [0001] The invention relates to a transmission gear set, in particular to a transmission gear set capable of suppressing knocking noise. Background technique [0002] The transmission structure includes components such as a case, a transmission shaft, a bearing, a synchronizer, and a gear, among which the transmission wheel pair composed of a driving wheel and a driven wheel is its core. According to different driving conditions, the transmission switches the torque transmitted by the gear system by changing the transmission gear, so as to obtain the required traction. In the neutral idling state of the transmission, no pair of gears actually transmits torque, and all driven wheels on the output shaft follow the driving wheel to idle without outputting power. In any other gear position, only one pair of gears is put into torque transmission, and the rest The driven wheel is still idling. When the driven wheel is idling without torque transmission, due to th...
