An autonomous floor cleaning robot includes a transport drive and control system arranged for autonomous movement of the robot over a floor for performing cleaning operations. The robot chassis carries a first cleaning zone comprising cleaning elements arranged to suction loose particulates up from the cleaning surface and a second cleaning zone comprising cleaning elements arranged to apply a cleaning fluid onto the surface and to thereafter collect the cleaning fluid up from the surface after it has been used to clean the surface. The robot chassis carries a supply of cleaning fluid and a waste container for storing waste materials collected up from the cleaning surface.

Disclosed is a wheel carrier for a suspension of a motor vehicle; and a motor vehicle comprising the wheel carrier. In a preferred system, the wheel carrier comprises a first carrier segment configured to carry a wheel of the motor vehicle at a wheel center; and a second carrier segment configured to couple the first carrier segment with a vehicle body of the motor vehicle. The second carrier segment comprises at least one groove, and the first carrier segment comprises for each groove a corresponding sliding pin configured to slidingly engage the respective groove such that the pin slides along the groove under vertical and/or horizontal displacements of the wheel center with respect to the second carrier segment.

State of the art track width adjustment mechanism fail to support track width adjustment while vehicle is in motion. They also require manual intervention, which causes inconvenience. The disclosure herein generally relates to wheel track adjustment, and, more particularly, to a changeable wheel track mechanism for track width adjustment (referred to as TWA mechanism). The TWA mechanism includes a steer and drive unit, a plurality of links, and a sliding unit. The TWA mechanism allows movement of a wheel in inward and outward directions, causing the track width adjustment. The track width is achieved by changing the wheel position to be at a wider position, or a narrower position, or any intermediate position. The TWA mechanism may be associated with any vehicle for which the track width adjustment is to be achieved.

An autonomous delivery vehicle having one or more caster wheels that may be held off the ground for a portion of the time that the autonomous delivery vehicle travels. Each caster wheel is mounted in a pivot with a centering mechanism to hold the caster wheels in a design orientation. The caster wheel in the design orientation maximizes the view of forward-looking sensors on the autonomous delivery vehicle. The centering mechanism uses a compression spring that drives a follower and swashshaft to apply a rotation force on the caster wheels. The rotational force urges the casters frame and wheels to return to a design position. The rotational force increases with the rotational difference between the caster rotational position and the design position.

An actuating mechanism for a caster that brakes and positions the caster by means of a cam mechanism that enables braking of the caster using minimum forces developed on the brake lever or brake rod. The mechanism helps to handle casters of patient support apparatuses in hospital and nursery facilities easily, using minimum force developed by caregivers or by an electronic caster brake systems if used for braking of casters of patient support apparatuses, as well. The mechanism may produce an outstanding decrease of noise level of castors on patient support apparatuses.

A trailer includes a set of removable castor wheels attached to a rear portion thereof, wherein the castor wheels are oriented to face rearwardly when the trailer is oriented in the traditional horizontal position. This arrangement allows the trailer to be tilted upwardly into a vertical orientation so that it rests on the castor wheels, thus providing an apparatus and method for easily moving and storing trailers more efficiently due to the reduced footprint required for such trailer storage. The castor wheels, in one embodiment, include mounting brackets that may be attached to the trailer using a securing rod, similarly to the mounting mechanisms commonly used for removably attaching trailer hitches into trailer hitch sleeves, thus rendering the castor wheels removable from the trailer when they are not in use for storage purposes.

A table leg assembly for supporting a table top. The table leg assembly includes a leg member having a lower end that defines an open interior. A tube end insert is received within the open interior at the lower end of each of the leg members. A threaded internal opening of the tube end insert receives an attachment rod of either a caster wheel assembly or a glide assembly. The glide assembly includes a glide member having a support foot mounted to the threaded attachment rod. A spacer is positioned along the attachment rod between the lower end of the leg member and the support foot. The spacer is movable along the attachment rod to cover the threaded attachment rod and lock the glide member in position. The attachment rod of the caster wheel assembly is received within the tube end insert to mount the caster wheel assembly to the leg member.

A mower front caster wheel system that includes a caster wheel assembly that rotates about a caster axis, and a stabilizer to be disposed in a bearing housing coupled to a frame of a mower such that a first portion of the stabilizer is in contact with a component that rotates with the caster wheel assembly and a second portion of the stabilizer is in contact with an internal surface of the bearing housing, to provide resistance to rotation of the caster wheel assembly relative to the bearing housing.

A trailer includes a set of removable castor wheels attached to a rear portion thereof, wherein the castor wheels are oriented to face rearwardly when the trailer is oriented in the traditional horizontal position. This arrangement allows the trailer to be tilted upwardly into a vertical orientation so that it rests on the castor wheels, thus providing an apparatus and method for easily moving and storing trailers more efficiently due to the reduced footprint required for such trailer storage. The castor wheels, in one embodiment, include mounting brackets that may be attached to the trailer using a securing rod, similarly to the mounting mechanisms commonly used for removably attaching trailer hitches into trailer hitch sleeves, thus rendering the castor wheels removable from the trailer when they are not in use for storage purposes.

A caster for equipment and furniture, the caster comprising a support element including a top element and a base element, wherein the top element includes an attachment bolt configured to attach the caster and the base element includes a wheel axle that supports at least one wheel, wherein a replaceable substantially circumferential one-piece support element cover made from a synthetic material that provides a continuous design surface is arranged at the support element.
