Title:
TORQUE CAM DEVICE AND CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
Japanese Patent JP2019031995
Kind Code:
A
Abstract:
To suppress occurrence of backlash between two cam members of a torque cam mechanism even when the mechanism does not transmit torque, in a torque cam device including a first torque cam mechanism for transmitting torque in a forward direction, and a second torque cam mechanism for transmitting torque in a backward direction.SOLUTION: A first following guide 94 for making input and output members 91A, 91B follow in a rotating direction when torque is transmitted in a backward direction, is disposed between a first input-side cam member 91A and a first output-side cam member 91B of a first torque cam mechanism 91, and a second following guide 95 for making input and output members 92A, 92B follow in the rotating direction when the torque is transmitted in a forward direction, is disposed between a second input-side cam member 92A and a second output-side cam member 92B of a second torque cam mechanism 92. The first following guide 94 and the second following guide 95 include guide members 94A, 95A having spiral guide grooves 94a, 95a, and pins 94B, 95B guided by the guide grooves 94a, 95a.SELECTED DRAWING: Figure 2
