Title:
ELASTIC CRAWLER
Document Type and Number:
Japanese Patent JP2020097274
Kind Code:
A
Abstract:
To provide an elastic crawler capable of effectively reducing sensible vibration while running.SOLUTION: While a rolling wheel 18 passes on a plurality of protrusion parts 44 formed at a rolling wheel passing surface 30, vibration with a shorter interval than steady vibration corresponding to a pitch of a core metal 32 can be generated; therefore, the vibration with the short interval generated while passing through the protrusion parts 44 is added to the steady vibration and hence an occupant becomes less responsive to the steady vibration generated while the rolling wheel 18 passes on the core metal part. Forming protrusion parts 44 at a position of a maximum amplitude value of upward excited vibration and/or forming the protrusion part 44 at a position of a minimum amplitude value of downward excited vibration can reduce an absolute value of an amplitude extreme value of synthesized excited vibration.SELECTED DRAWING: Figure 3
