摘要： An automatic speed reducing wheel includes a wheel unit and a speed reducing unit. The wheel unit includes a wheel seat, a wheel axle passing through the wheel seat, and a roller rotating about the wheel axle. A plurality of blockers is disposed on one side of the wheel frame in adjacent to an edge thereof in a radiation shape arrangement. The blockers rotate along with the roller. The speed reducing unit includes a fixing seat and a sliding member. The fixing seat is on one side of the roller and includes a sliding bore. The sliding member is slidably disposed in the sliding bore and includes an elastic portion having a blocking portion. When the roller moves downhill, the blocking portion of the sliding member protrudes out of an outer side of the sliding bore to interrupt a rotation route of the blockers, achieving a speed reducing effect.

摘要： This invention relates to gravity reactive braking systems. According to the invention there is provided a brake system to control speed in a forward direction for descending inclined surfaces and a brake system for controlling rollback when ascending an inclined surface. The speed pacer braking assembly includes a downhill activator for selectively engaging a disc brake system when a predetermined inclined is reach. The anti-rollback assembly comprises a pair of graded brake cam structures operatively disposed adjacent wheels wherein the natural pull of gravity and the configuration of the cams operate to allow passage of wheels in both directions when on flat surfaces and in only a single direction when on an incline. When on an incline, gravity operates to dispose cams relative to the wheels such that rotation of wheels in one direction is hindered by a thickening of cam body caused by rotation of cam about its axis. Both systems include adjustment means for setting the incline angle at which brake assemblies will operate to hinder wheel rotation in the undesired direction.

摘要： A molded braking and support wheel assembly for a multi-wheeled wheelchair for a handicapped person. The wheel assembly includes a braking support wheel molded as a single unit of plastic or plastic-like material having concentric components including a tire receiving rim, a wheel bearing and brake assembly receiving hub, and spaced wheel spokes substantially radially extending between the hub and rim. A ring or band-shaped metal brake drum is also molded as a unit into the hub, the brake drum having a generally cylindrical inner braking friction surface and plastic-interlocking outer surface features which permanently interlock with the plastic material when the braking support wheel is mold formed. The plastic-interlocking outer features are molded with the hub into a single unit with the support wheel to secure the brake drum from relative movement in the hub. The brake drum defines a generally cylindrical cavity for operatively receiving the brake assembly. The hub includes a wheel bearing cavity coaxial with said brake drum for receiving spaced wheel bearings positioned therein.
