無限軌道
Document Type and Number:
Japanese Patent JP4388624
Kind Code:
B2
Abstract:
A track (10) for a vehicle is typically carried by a plurality of wheels (12, 14, 16). Tread-wheel vibration is created when the track (10) passes between a wheel and the ground over which the vehicle is traveling. A track (10) includes a plurality of external lugs (32) that engage the ground when the track (10) is in use. Each external lug (32) has a tread angle (a) indicating the angle at which the lug is disposed to the longitudinal axis (34) of the track (10), a tread pitch (P) and a lug width (H). A wheel (16) contacting the interior of the track (10) has a width (B). A tread design that minimizes tread-wheel vibration has the pitch (P) of the lugs (32) substantially equal to the wheel width (B) multiplied by the tangent of the tread angle (a).
