Planet gear clutch

Abstract

The invention provides a planet gear clutch. The planet gear clutch comprises a clutch body (10) with a clutch control mechanism (20), a clutch control mechanism (30), a planet gear input stage (40) and output stage (50) and a control input stage degree of freedom coupling module (32; 45). The planet gear output stage consists of two sun gears, which are connected with an input-stage planet carrier and a gear ring; when a torque input by the planet gear input stage is controlled by the coupling module, reverse resistance and active torque are generated and transferred to the output stage (50);a planet gear engaged with the two sun gears is acted on the gear ring thereof to cause interlocking of an output-stage gear ring, the planet gear and the planet carrier; a working mode is from two-ration to one-degree-of-freedom; active torque is output from a shaft extension end of the planet carrier; and vice versa. All gears are located in an engaged state in the separation and joint processto realize no-gap separation of the clutch; and a no-friction torque transfer function is combined.

Description

technical field [0001] The invention relates to a clutch, in particular to a planetary gear clutch, a clutch transmission device used for separating and combining a master machine and a slave machine in mechanical transmission, and belongs to the technical field of mechanical transmission. Background technique [0002] In the process of realizing the present invention, the inventor found that the conventional clutches in the prior art have the following problems. The existing mechanical transmission is used to separate and combine the clutches of the driving machine and the driven machine, and most of them use the mutual friction set on the drive shafts of the driving machine and the driven machine. Technical solution for components to transmit torque. A common clutch on a vehicle is to rely on the friction discs arranged on the driving drive shaft and the passive drive shaft, and under the action of an external force of an axial spring (or hydraulic pressure, electromagneti...

AI Technical Summary

Problems solved by technology

In this technical solution, when the torque to be transmitted is greater, the axial pressure is required to be greater, and auxiliary boosting measures such as hydraulic transmissions must be added, and the radial size of the friction disc will increase accordingly, and the volume of the clutch will also increase accordingly. Large, due to the increase of the axial force, the separation operation force also increases, which makes the separation operation difficult. In addition, when this kind of friction clutch is in the process of engagement or in the half-clutch state, due to the large speed difference between the main and slave transmission shafts, the combination A large impact and relative sliding are generated instantly, causing the clutch friction plate to slip, generating high heat, and ablation, wear and damage are inevitable, causing adverse effects on production, use and maintenance

These reasons have created technical obstacles for the clutches that transmit torque by friction to be used in large and medium-sized mechanical equipment.
