A releasable wheel assembly includes a bracket having multiple bosses, each boss including a hole that receives an axle. A pair of wheels are mounted on the axle and a pair of locking caps fit over respective ends of the axle, the locking caps each including a clip for engaging the axle at a circumferential groove to prevent movement of the locking cap along the axle. The wheel assembly can be mounted to a carry bag or other storage unit by mounting the bracket to the storage unit, where the wheels and axle can be easily removed from the bracket.

A hybrid wheel including a functional rim, a center disc, and a wheel face insert, wherein the wheel rim and the center disc are made of a specified material, and wherein the wheel face insert is made of a dissimilar material. The wheel face insert can be secured to the center disc by at least one of screws, pins, rivets, or structural adhesive, and/or the wheel face insert can be secured to the functional rim by at least one of screws, pins, rivets, or structural adhesive.

The invention relates to an electric motor (24) designed for driving a vehicle (10) which can be moved by a person, particularly a pram (11), walker or the like, having a rotor (52), which comprises at least one holder (80) for a wheel (14, 16), and a stator (54) which can be connected through a housing (38) to a load-bearing structure (12) of the vehicle (10). According to the invention, the housing (38) has a status display (84) on which parameters, particularly power parameters, of the electric motor (24) can be displayed so as to be visible from the outside.

A brake rotor includes a friction portion, a hat portion axially extending from the friction portion and including a top face that is axially displaced from the friction portion and a side wall that extends from the friction portion to the top face, and a nose portion which extends axially from the top face of the hat portion away from the friction portion.

The disclosure provides a wheel, drive wheel and wheel chair. The wheel includes an annular rim and a disk covering the rim on one side in an axial direction of the rim. The disk of the wheel includes a skin and a cushion member. The skin is formed of a fiber-reinforced material. The cushion member includes a cushion part and a shape retaining part. The cushion part is formed of a shock absorbing material and is disposed adjacent to the skin. The shape retaining part is formed of a fiber-reinforced material and is disposed adjacent to the cushion part.

A training wheel assembly includes an assembly frame and a training wheel rotatably attached to the assembly frame. The training wheel has a wheel axle extending therefrom and defining an axis about which the training wheel rotates, and an annular hub concentric with the wheel axle and rotationally fixed therewith. A plurality of successive ratcheted teeth facing the assembly frame form a circumferential inner edge of the wheel. An elastically deflectable tongue is attached to the assembly frame and is selectively extendible into a rotational path of motion of the ratcheted teeth, whereby upon rotation of the training wheel with respect to the assembly frame about the axis, contact of the elastically deflectable tongue with successive teeth of the plurality of ratcheted teeth generates an audible sound indicating that the training wheel is rotating.

An anti-rolling wheel includes: a ring-shaped main wheel; an inner frame positioned inside the main wheel, wherein the inner frame comprising at least two auxiliary wheels that come into contact with an inner surface of the main wheel and rotate when the main wheel is driven; and a sliding block provided to be movable under the guide of the inner frame.

A lawn mower includes a blade housing and a height adjusting mechanism for adjusting a height of the blade housing with respect to the associated ground. The height adjusting mechanism includes rear wheel support members for supporting rear drive wheels. Each rear drive wheel includes a cover having an exterior cover part and an interior cover part. The interior cover part is directly connected to one of the support members without the use of separate associated mechanical fasteners.

A wheel and hub assembly. Such a wheel includes split adapters, split hubs and split wheels. The assembly is attached to any beach chair or other article of manufacture which has a rod or pipe in its structure. Also, the wheel can be adapted on variously sized pipes and enable a user to easily pull/roll a beach chair or other articles of manufacture on various surfaces including a sandy beach or lawn.

A robot cleaner including: a cleaner body; a motor, configured to be fixed to the cleaner body, and provide a rotational force; a gear unit configured to transmit the rotational force of the motor; a wheel configured to rotate and drive the cleaner body according to the rotational force of the motor transmitted by the gear unit to the wheel; and a suspension including a first end portion pivotally supportable on a pivot of the cleaner body, which is spaced apart from a rotary shaft of the motor, and a second end portion to extend from the first end portion and support the wheel to move up and down with respect to the cleaner body as the second end portion moves in a first direction and a second direction around the pivot of the cleaner body.
