The hub flanges include a plurality of accommodation sections to receive one spoke head each. The accommodation sections are axially disposed on the hub flanges. Each of the accommodation sections has one spoke feed-through assigned to it, through which an accommodated spoke can be guided out of the accommodation section. Two spoke feed-throughs each are provided with one joint and circumferentially closed outlet opening in the hub flanges. The hub flanges enclose the outlet opening integrally.

Some embodiments are directed to an adjustment assembly for changing width of a vehicle including at least one pair of wheels, where the adjustment assembly is embedded in the vehicle and is connectable to a pair of front, middle or rear wheels thereof. The adjustment assembly includes, inter alia: a foldable unit connectable to the pair of wheels of the vehicle, configured for changing its overall length over a predefined axis Y connecting the centers of the pair of wheels, for adjusting a distance between the pair of wheels it connects to; and a tilting unit operatively associated with the pair of wheels of the vehicle to which the foldable unit connects. The tilting unit is configured for changing angular positioning of the pair of wheels in respect to the Y axis, during driving of the vehicle when folded or unfolded.

A first labyrinth seal includes: a drive shaft side annular protrusion that is formed on one of the slinger and the drive shaft seal plate and that protrudes over the circumference of the drive shaft; and a drive shaft side annular groove that is formed on the other of the slinger and the drive shaft seal plate and that recedes over the circumference of the shaft. A second labyrinth seal includes: a carrier-side annular protrusion that is formed on one of the carrier seal plate and the planetary carrier and that protrudes over the circumference of the shaft of the planetary carrier; and a carrier-side annular groove that is formed on the other of the carrier seal plate and the planetary carrier and that recedes over the circumference of the shaft.

A spoke wheel includes a light alloy rim, a hub, and a plurality of wire spokes connecting the rim with the hub. The rim includes mounting flanges provided at asymmetrical positions with respect to a widthwise center of the rim and is connected with the hub by assembling the spokes to the mounting flanges. The spokes are disposed by being offset to the widthwise center of the rim.

A hub and a wheel having such a hub are provided. The hub includes a hub shell and an axle to rotatably receive the hub shell. The hub shell is provided with circumferential hub flanges serving for accommodation and defined orientation of a plurality of spokes. Each of the spokes has a spoke body and a spoke head. The hub flanges include a plurality of accommodation sections receiving a spoke head each. Each of the accommodation sections has one spoke feed-through assigned to it through which an accommodated spoke can be guided out of the accommodation section. The hub flange includes two different types of accommodation sections. A first type includes a circumferentially closed spoke feed-through and a second type, a circumferentially opened spoke feed-through.

A pair of wheels coupled together by an adjustable axle mechanism. A right straight-line linkage coupled to a right wheel and a left straight-line linkage coupled to a left wheel. The right straight-line linkage and the left straight-line linkage are connected together and each move independently from each other between an extended position and a retracted position.

A castor suspension system for suspending a first castor at a patient support device is provided. The castor suspension system comprises a pivoting suspension link pivotably attachable to the patient support device, and a springy element comprising a leaf spring made of a band deformed such that the band makes at least one U-turn so that the band has a first leg and at least one second leg. One of the first leg and the at least one second leg is provided with a first support portion supported on the pivoting suspension link, and the other of the first leg and the at least one second leg is provided with a second support portion for supporting the springy element with respect to the patient support device such that the springy element is configured to provide a pre-stress force to the pivoting suspension link.

The present disclosure relates to a caster wheel assembly (1), comprising: a caster housing (3) provided with an axial channel, a spindle shaft (7) configured to be received by the channel of the caster housing (3), which spindle shaft (7) is inclined relative to the vertical plane when mounted in the caster housing (3) and the caster wheel assembly (1) is in use resting on a horizontal support, the caster housing (3) and the spindle shaft (7) being configured to rotate freely relative to each other, a caster wheel fork (9) having a wheel axle (11) configured to be arranged offset relative to a central axis of the spindle shaft (7), to provide a trail functionality, and a height adjustment mechanism (6) configured to adjust an axial position of the spindle shaft (7) relative to the caster housing (3) based on a rotational position of the spindle shaft (7) in relation to the caster housing (3).

A strut type suspension device has a retractable strut (111) that connects to an upper portion of an in-wheel motor drive device (10) so as not to relatively move; and a swingable lower arm (116) that is coupled to a lower portion of the in-wheel motor drive device in any direction, and permits vertical swinging of the in-wheel motor drive device and also permits steering of the in-wheel motor drive device about a steering shaft (S) that passes through a coupling point (119) between the lower arm (116) and the in-wheel motor drive device. An axis (M) of the motor portion (21) of the in-wheel motor drive device is arranged above a height of the coupling point (119) of the lower arm (116).

A spare wheel assembly comprising a tire and a rim to which the tire is attached is disclosed. The rim includes a center mounting plate having a center bore, inner and outer opposed flanges, and a disk between the center bore and the flanges. The disk includes a pair of elongated, curved slots formed on opposite sides of the center bore. Each of the slots is an ergonomically-formed hand hold for receiving fingers of an operator's hand. The inner and outer opposed flanges of the rim define perimeters of the rim between which the tire is held. The curved slots are concentric with respect to the perimeter of the outer flange and with respect to the center bore. A centerline is formed radially through the assembly. The disk is positioned on one side of the centerline and the mounting plate is positioned on the other side of the centerline.
