The principle of work of this scheme is: pressure rings moves to inner attrition piece direction under the effect of external manipulation mechanism, lever axial direction part footpath is inwardly moved by pressure rings inner face, now the longitudinal section of lever promotes pressing plate to move in friction plate direction outward, under the effect of pressing plate and nut, external friction sheet and inner attrition piece will fit together and compacted, clutch coupling is in bonding state, now torque is delivered to driven shell end from sleeve end, when under the effect of external manipulation mechanism, pressure rings oppositely moves, lever is produced reactive force by extension spring, lever resets, pressing plate unclamps, in, outer clutch disc is separately, clutch coupling is in separate stage.
The useful effect of this scheme is: adopt end face to coordinate by between inside and outside friction plate, mechanical shock problem when avoiding conventional clutch tooth shape structure to engage, simultaneously by setting up extension spring between lever axial direction part and axle sleeve the 3rd groove, thus make lever promotion pressing plate make can there be certain elasticity when inner attrition piece and external friction sheet, therefore inside and outside friction plate in conjunction with time more steady.
Further, driven shell and transmission shaft adopt circular flat key to be connected, and axle sleeve adopts circle flat key to be connected with transmission shaft, flat key connection disassembling, easy for installation, while also can meet the requirement of transmission of power.
Further, axle sleeve being also provided with set nut, nut and set nut end face offset, and set nut can prevent the rotation of nut, keep all even of gap between inner attrition piece and external friction sheet to stablize.
Further, pressure rings is connected by dive key with axle sleeve, and dive key is except for except the connection between pressure rings and axle sleeve, moreover it is possible to for moving axially of pressure rings provides certain guide effect.
