Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the clutch torque-conversion adjusting device of the present invention mainly comprises a power input shaft 12, a driving disk 10 and a driven disk 9 arranged on the power input shaft 12, and a power output shaft 13 arranged corresponding to the power input shaft 12, wherein one end of the power input shaft 12 is provided with a sun gear 2, the sun gear 2 is integrated with the power input shaft 12, the sun gear 2 is arranged at the center of a housing 1 arranged close to the driven disk 9, the sun gear 2 is engaged with at least one planetary gear 3, the centers of the planetary gears 3 are respectively provided with planetary gear shafts 4, the planetary gear shafts 4 are fixed inside the housing 1, a high-pressure oil chamber 6 is formed at one side where the sun gear 2 and the planetary gears 3 are engaged, a low-pressure oil chamber 5 is formed at the other side, a low-pressure oil chamber oil inlet pipe 7 is arranged on the low-pressure oil chamber 5, the high-pressure oil cavity 6 is provided with a high-pressure oil cavity oil outlet pipe 8, the high-pressure oil cavity oil outlet pipe 8 is provided with a valve 11, and the power output shaft 13 and the shell 1 are integrated.
The working principle of the clutch hydraulic torque conversion adjusting device is as follows:
when the driving disc 10 is separated from the driven disc 9, the power input shaft 12 drives the sun gear 2 to rotate, the sun gear 2 further drives the planet gear 3 to rotate, so that hydraulic oil is sucked into the low-pressure oil chamber 5 through the low-pressure oil chamber oil inlet pipe 7, when the sun gear 2 and the planet gear 3 are meshed to rotate, the hydraulic oil is extruded into the high-pressure oil chamber 6 through the teeth of the sun gear 2 and the planet gear 3 and gaps between the teeth, the hydraulic oil extruded into the high-pressure oil chamber 6 is outwards extruded through the high-pressure oil chamber oil outlet pipe 8 and the valve 11, and at the moment, the shell 1 and the power output shaft 13 integrated with the shell 1 do not rotate together with the power input shaft 12.
When the valve 11 is slowly closed, the hydraulic oil in the high-pressure oil chamber 8 is discharged under resistance, the hydraulic oil pressure in the high-pressure oil chamber 6 rises, and a reaction force is generated between the planetary gear 3 and the sun gear 2, at this time, the planetary gear shaft 4 drives the shell 1 to rotate along with the power input shaft 12 in the same direction, the shell 1 drives the power output shaft 13 to output power outwards, the smaller the valve 11 is closed, the larger the oil pressure in the high-pressure oil chamber 6 is, the larger the reaction force of the hydraulic oil on the planetary gear 3 and the sun gear 2 is, and the larger the torque force of the power output shaft 13 is, the larger the torque force of the shell 1 is, which is generated by the planetary gear shaft 4.
When the valve 11 is completely closed, the hydraulic oil in the high-pressure oil cavity oil outlet pipe 8 completely stops flowing, the hydraulic oil in the high-pressure oil cavity 6 cannot be compressed, the planetary gear 3 is forced to rotate around the sun gear 2 in the same direction, at the moment, the rotating speed and the torque of the power input shaft 12 and the power output shaft 13 are basically the same, the driven disc 9 and the driving disc 10 are locked into a whole through a clutch principle, the power input shaft 12 is rigidly connected with the shell 1 through the locked driving disc 10 and the locked driven disc 9, the power is directly output outwards through the power output shaft 13, the valve 11 is opened, the hydraulic oil pressure in the high-pressure oil cavity 6 is reduced, preparation is made for the next working cycle, and the clutch hydraulic torque conversion adjusting device completes one working cycle.
