The adaptive multi-plate sequencing large-torque friction clutch device comprises a power input mechanism used for inputting power and a main shaft used for outputting the power, an inner plate spiral raceway sleeve, a friction clutch and an elastic element set are installed on the main shaft in a sleeving mode, the friction clutch comprises a friction plate supporting part arranged on the inner plate spiral raceway sleeve, a plurality of outer friction plates and a plurality of inner friction plates, wherein the outer friction plates and the inner friction plates are alternately arranged between the friction plate supporting part and the inner plate spiral raceway sleeve, all the outer friction plates can slide in the axial direction of the friction plate supporting part, and all the inner friction plates can slide in the axial direction of the inner plate spiral raceway sleeve. According to the scheme, one-way transmission of the power can be achieved, meanwhile the multiple outer friction plates and the multiple inner friction plates which are alternately arranged are utilized, thus born torque is dispersed on each outer friction plate and each inner friction plate, the friction loss is greatly lowered, the defect of poor wear resistance of a traditional disc-type friction clutch is overcome, thus the stability and reliability of the whole device are high, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of clutch mechanisms, in particular to an adaptive multi-plate sorting high-torque friction clutch device with a one-way transmission function. Background technique [0002] The friction clutch uses the mechanical friction between the friction surfaces to transmit the torque from the driving shaft to the driven shaft, and can engage or disengage the main machine and the driven shaft according to the work needs. Existing friction clutches do not have the function of one-way transmission of power, so they cannot be directly applied to some special application scenarios, such as the transmission of pure electric vehicles. [0003] Moreover, the existing friction clutches are mainly disk-type friction clutches including active friction discs and driven friction discs, which have poor wear resistance. The defect of short life cannot be used as a high-torque power transmission device. Therefore, a multi-disc fri...

Problems solved by technology

When the multi-plate friction clutch is switched from the combined state to the disengaged state, the friction plates will be distributed adaptively under the action of the oil film and inner cavity pressure, that is, the outermost friction plate will separate first, and then the inner one will separate. By analogy, the friction plates are separated one by one from the outside to the inside, and since the friction plates are in an oil-filled wet room environment, the process of self-adaptive distribution of the friction plates takes a long time, in order to ensure the response time and speed of the multi-disc friction clutch, it will be The number of friction plates is limited, so that the existing multi-plate friction clutches cannot bear large torque

[0004] In addition, in a wet room environment full of engine oil, if the friction plates of the multi-plate friction clutch are not completely separated, it is often that some adjacent friction plates stick to each other, or even most of the friction plates stick to each other. Only a few of the friction plates are separated, so after long-term use, the wear still only occurs on these few friction plates, which deviates from the original design intention and greatly reduces the wear resistance of the multi-disc friction clutch, resulting in an unsatisfactory service life

[0005] Therefore, a new design of a new friction clutch device is urgently needed, which can not only realize the one-way transmission of power, but also solve the defects of poor wear resistance of the friction disc, short service life, and cannot be used as a high-torque power transmission device.
