A caster wheel brake system for carts and other wheeled articles is operable to secure caster wheels against rolling rotation along their horizontal rotation axes. The system includes a pivotable parking brake lever, an actuator arm, and a torque shaft extending between the brake lever and actuator arm. The brake lever includes a distal end portion for selectively engaging a caster wheel, a proximal end portion opposite the distal end portion, and a pivot coupling, the latter being pivotably secured to the cart or wheeled article. An actuator arm extends outwardly from a distal end portion of the torque shaft, with the actuator arm slidably engaging the proximal end portion of the brake lever. The torque shaft and the actuator arm are rotatable together to urge the brake lever toward the braking or non-braking position

A caster for equipment, furniture and medical equipment, the caster including a support arm that includes a base portion and a top portion and receives an attachment bolt wherein the base portion supports a wheel axle that supports at least one wheel; a direction fixing device; and a movable blocking element configured to lock the direction fixing device, wherein the moveable blocking element is in direct or indirect friction contact with the wheel so that a friction force that is caused by the friction contact causes a locking of the direction fixing device and a direction fixing of the caster in a first direction when the caster moves in the first direction.

An axle assembly includes a first axle shaft. The first axle shaft includes a first conduit. A second axle shaft includes a second conduit. The first conduit and the second conduit are in fluid communication through a chamber. A differential is operatively connected to the first axle shaft and the second axle shaft. The chamber is at least partially disposed within the differential.

Disclosed is a folding bicycle, including: a front wheel, a rear wheel, a handlebar, a main frame, a support frame, a pedal mechanism, a first safety clamp, and a second safety clamp, the first safety clamp being configured to secure relative position between the support frame and the main frame; and a second rotating shaft is disposed between the through-hole and the position where the main frame joins with the handlebar. The folding bicycle disclosed offers an advantage of portability.

A wheel brake arrangement for a wheel of a vehicle, said wheel brake arrangement comprising a wheel hub (102) comprising an outwardly facing gear teeth arrangement (104) arranged in a circumferential direction thereof; and a brake disc (106) comprising an inwardly facing gear teeth arrangement (108) arranged in meshed connection with the outwardly facing gear teeth arrangement of the wheel hub for preventing a relative circumferential movement between the brake disc and the wheel hub, wherein one of the wheel hub and the brake disc comprises a circumferentially arranged groove (110); wherein the wheel brake arrangement further comprises at least one retainer (112) connected between the wheel hub and the brake disc for preventing a relative axial movement between the wheel hub and the brake disc, wherein the at least one retainer is at least partially arranged in the circumferentially arranged groove (110) of one of the wheel hub and the brake disc.

A wheel bearing arrangement for a motor vehicle, having a wheel hub and a wheel bearing for rotatably mounting the wheel hub on a wheel carrier. The wheel bearing has an outer ring and an inner ring. A wheel flange extends from the wheel hub in a radial direction and has a brake disc receptacle which is open in the direction facing away from the outer ring and is formed by a recess in the wheel flange and has a brake disc bearing face for a brake disc. A seal-receptacle space is formed in the wheel flange on its side facing the outer ring in an axial direction, in which seal-receptacle space there is a wheel bearing seal. A rim-centering seat element extends from the wheel hub and runs in the direction opposite the brake disc bearing face with respect to the brake disc receptacle.

The present invention relates to a novel design for quick tyre change in rear dual wheel assembly in a heavy transport vehicle. The invention provides a safe design that comprises a two-piece segmented saddle lock ring retained in position by an endless ring. A self-locking taper provided on the inside of endless ring can be pressed against the taper provided on the two-piece segmented saddle lock ring. The endless ring retaining the two-piece segmented saddle lock rings due to wedge action of self-locking taper cannot move from its position until an external force is applied on the endless ring towards the direction of the tyre position. The endless ring acts as a hood over the two-piece segmented saddle lock rings and prevents any loose parts flying off the rim during the tyre burst. Further in this safe design both inboard and outboard rim tyre support components are identical as both rims are of same diameter.

Particular embodiments disclosed herein provide a retractable guard assembly coupled to a caster of a mobile equipment, comprising one or more first guards comprising corresponding one or more guard toeholds and one or more second guards. When the one or more first guards and the one or more second guards are in a fully retracted state, fully compressing any one of the one or more guard toeholds causes the one or more first guards and the one or more second guards to transition into a fully deployed state. When the one or more first guards and the one or more second guards are in a fully deployed state, fully lifting any one of the one or more guard toeholds causes the one or more first guards and one or more second guards to transition into the fully retracted state.

A portable roadside assistant device; a system which includes a tool designed to ease the process of removing and changing a tire for any user. The present invention is superior to other systems in that it effectively automatically loosens and tightens lug nuts to assist users in changing a flat tire.

A hub or wheel assembly includes a retaining element, biasing element, and hand-maneuverable release mechanism. The housing includes an axle bore configured to receive an axle and a pin sleeve including a first end in fluid communication with the axle bore, a second end, and a conduit between the first end and the second end. The retaining element is within the conduit and is configured to operatively engage a groove in an axle. The biasing element is within the conduit and is configured to bias the retaining element towards the axle bore. The hand-maneuverable release mechanism is configured to displace the retaining element away from the axle bore.
