Problems solved by technology

The disadvantage of this shoe-type automatic clutch is that when the shoe is in a free state, the three shoes cannot form a perfect circle. Only under the action of centrifugal force, the moving point end of the centrifugal arm moves, and the arc on the three shoes However, even in this state, the arc surface of the friction block bonded to the shoe block cannot completely contact the clutch cover, and the contact area is reduced, resulting in a small transmitted torque. , and the wear of the friction block is u

Example Embodiment

[0011] Referring to FIGS. 1 and 2, the clutch cover 8 is connected with the driven gear 18 with a shaft hole, and is tightly fixed by rivets 19. The shaft hole of the driven gear 18 is a stepped hole. The driving disc 9 is located in the clutch cover 8. The driving disc 8 is fixedly connected to a shaft sleeve 14 with a spline hole by welding. The shaft sleeve 14 and the driven gear 18 The same axis line, the sleeve 14 is slidingly fitted with the inner wall of the large end of the stepped hole of the driven gear 18 through the unidirectional device 17, and the sleeve 14 with a splined hole corresponds to the centrifugal shoe 2 with a rubber sleeve on one end circumference Set of 16. The driving disc 9 is uniformly provided with three pin shafts 3, and the three pin shafts 3 are equally divided by 360°, and they are respectively fixed on the driving disc 9 by riveting, or fixed on the driving disc 9 by pressing and fixing nuts to achieve the same effect. Three centrifugal shoe blo...

Abstract

The invention discloses a mosque automatic clutch, wherein an active cover of the clutch frame is connected with an axial sheath with a spline hole, the active cover is arranged with at least two eccentric mosque blocks which can radial move on the active disc, the inner arc of each eccentric mosque is arranged with a radial sliding groove at middle, the sliding groove of each mosque is sliding engaged with a pin axle of the active disc, the outer arc of each mosque block is adhered with a friction block between which and the inner wall of the clutch frame a clearance space is arranged, each eccentric mosque is arranged with an arc groove while all grooves are connected to form an annular groove, two ends of a flexible spring are connected to be arranged in the annular groove, the annular groove is shaded by a baffle plate, and a baffle ring clamps a pin axle to axially position the eccentric mosque blocks. The invention can contact the arc face of the friction block completely with the clutch frame when in work, to improve torque and make friction uniform to prolong the service life of friction block.

Description

technical field [0001] The invention relates to a shoe-type clutch, in particular to a shoe-type automatic clutch for a motorcycle engine. Background technique [0002] The shoe clutch commonly used in motorcycle engines is generally installed on the crankshaft of the engine. It is characterized by relying on the combination or separation of the shoe and the clutch cover to realize the transmission and interruption of engine power. The existing shoe-type automatic clutch is generally composed of three centrifugal arm-type shoes, and each centrifugal-arm shoe is formed by spot-welding several steel plates with different shapes. The process is complicated and the cost is high. The arc surface of the centrifugal arm type shoe is bonded with a friction block, the fixed point end of each centrifugal arm type shoe block is hinged with the driving disc through a pin shaft, and the moving point end is connected with the fixed point end of another shoe block through a tension spring ...
