Title:
COUPLING DEVICE
Document Type and Number:
Japanese Patent JP2018118551
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a novel coupling device capable of transmitting larger torque than a differential rotation sensitive type coupling device while avoiding a tight corner braking phenomenon only with mechanical constitution.SOLUTION: A coupling device 20 according to the present invention comprises a housing 212 capable of rotating in one body with a main driving wheel side, a clutch part 22 provided within the housing and transmitting driving torque from the main driving wheel side to a driven wheel side, a differential rotation sensitive type coupling 70, and a cam part 23 moving in a direction Ya to press the clutch part, and boosting and transmitting torque generated at the differential rotation sensitive type coupling 70 to the clutch part as pressing force, and is so formed that a ratio of boosting by the cam part 23 is small when a rotating speed difference between the main driving wheel side and driven wheel side is mall, but large when the rotating speed difference between the main driving wheel side and driven wheel side is large.SELECTED DRAWING: Figure 2
