Wheeled type clutch

The wheeled type clutch of the utility model relates to the field of the power transmission clutching device, compising a belt pulley, a gland, a friction driven plate, a driving piece, a pressure plate, a releasing lever, a bearing and an adjusting bolt, etc. The cavity of the belt pulley is successively provided with the pressure plate, the friction driven plate, the driving piece, etc. More than 6 groups of the spring seat pits are respectively arranged on the side of the belt pulley corresponding to the pressure plate. An outer spring and an inner spring are arranged in the inner part of the cavity of the belt pulley. The cavity wall of the belt pulley provides more than 6 slide ways of the driving piece corresponding to the concave shoulder of the pressure plate. The inner side of the slide way is parallelly provided with the driving piece and the pressure plate, which can do parallel displacement in the inner side of the slide way. The usage of the scheme causes the wheeled type clutch to have a large spring pressure and can avoid the clutch sliding more effectively. The performance of the power transmission is improved; the abrasion of the slide way on the clutch is reduced and the service life of the clutch is extended for the reason of the increased slide ways, thus the wheeled type clutch can receive the higher requirement of the power transmission.
