摘要:
A wheel assembly includes a tire, having each bead seat angle in the range of 10 degree to 12 degree with respect to the axis of rotation, preferably 11 degree, and an aspect ratio of less than 60%, and a wheel rim, having a circumfurential well and a bead support surface angle also in the range of 10 degree to 12 degree, each bead support surface terminating in an upstanding flange overlapping a radially inner portion of the tire to support the sidewall of the tire. The flanges may be part circular in cross section defining a segment of approximately 135 degree, the radius of curvature being greater than 0.5 inches and preferably 0.75 inches.
摘要:
A wheel assembly includes a tire having bead seat angle in the range 10° to 12°, preferably 11°, and an aspect ratio of less than 60%. Reduced bounce and improved bead retention is obtained. The flange is curve and supports the sidewall of the tire in flexure to reduce rolling of the bead seat;
