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.

Abstract

The invention discloses an adaptive multi-disc sorting high-torque friction clutch device with a one-way transmission function, which includes a power input mechanism for inputting power and a main shaft for outputting power, and an inner spiral raceway is set on the main shaft sleeve, friction clutch and elastic element group, the friction clutch includes a friction plate support set on the inner spiral raceway sleeve and a number of outer friction plates and inner friction plates alternately arranged between the friction plate support and the inner spiral raceway sleeve For the friction plates, each outer friction plate can slide axially along the friction plate support member, and each inner friction plate can slide axially along the inner spiral raceway sleeve. Using the above scheme, one-way transmission of power can be realized. At the same time, a number of outer friction plates and inner friction plates arranged alternately are used to disperse the received torque on each outer friction plate and inner friction plate, which greatly reduces the friction loss and overcomes the traditional friction loss. The defect of poor wear resistance of the disc friction clutch makes the overall device have high stability and reliability and a long service life.

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...
