An airless flexible tire comprising a belt, drive lugs, and traction lugs. The drive lugs extend inwardly from the belt and form annularly spaced, rigid, high torque points. The traction lugs extend outwardly from the belt and are annularly offset from the drive lugs so as to form flexible sections that deflect radially inwardly when the tire engages the ground. Each traction lug has an effective height as a function of its actual height, the angle that the traction lug extends relative to a radial axis, the angle of the traction lug's distal surface, and the amount the tire deflects radially inwardly near the traction lug so as to at least partially equalize a rolling radius of the wheel to reduce torque generated near the high torque points.

The cleaning device is for cleaning the inner surface of pipes. The method is for manufacturing the cleaning device and the use is of a vehicle anti-skid chain for cleaning the inner surface of a pipe. The cleaning device has a sleeve, to which are attached studded chains composed of steel links and surface hardened.

This present invention relates to an anti-skid device adapted to being mounted on tyres of the vehicle wheels to provide traction and wheel to ground contact enhancement in snowy and icy conditions. The device includes a central housing 2 from which protrudes radially three arms 3 which are extended at the outer end by anti-slip components 10 transversally embracing the tread of the tyre. The anti-skid device have a locking mechanism that consists of a locking element 24 with teeth engaging with teeth on the inner circumference of the housing 2. A handle 16 integrated into the hub 4 interfaces with the locking element 24 to securely maintain the locked status when the device is mounted onto the wheel.

A plurality of disposable single fabricated piece tire grips with friction contact surfaces and cable ties ratchet mounted on wheel contact surfaces of tires mounted on wheel hubs with openings allowing the grips to secure there through for easy application and fits all tires regardless of size.

A wheel traction device is adapted for providing traction for a wheel of a vehicle to escape from a mud ground during rotation of the wheel, and includes: a guiding unit having a guiding portion adapted to abut against the wheel; a bearing unit that is detachably connected to the guiding unit, and that has a bearing portion adapted to be positioned on the mud ground such that, during rotation of the wheel, the bearing unit and the guiding unit are prevented from being driven by the rotation of the wheel to move relative to the mud ground, thereby allowing the wheel to roll over the bearing portion under guidance of the guiding portion; and a fastening unit that detachably fastens the bearing and guiding units together.

An anti-skid arrangement for a vehicle is disclosed. The anti-skid arrangement includes a friction wheel including a hub and a ring arranged around the hub, and a chain plate attached to the hub, wherein the chain plate includes several chains intended to be thrown under the tire in order to increase friction between the tire and the ground. The hub includes two parts clamping the ring. Further, an inner side of the ring is provided with grooves extending in a tangential direction along the ring and facing each hub part, and the two parts are provided with protrusions engaging the grooves.

The engagement between the tangential grooves and the protrusions in the hub will secure the ring firmly, even when the tread of the ring is worn down.

A quick connect tire traction system for providing traction to a tire on a vehicle wheel. The quick connect tire traction system includes an expansion strap coupled to one or more tire traction devices, an inner support coupled to the expansion strap with a rotation member, an outer extension telescopically coupled to the inner support, a rim mount coupled to the outer extension, the rim mount configured to receive one or more locking pins, and an elastic element extending between the inner support and the outer extension. The elastic element is adapted to bias the tire traction devices toward the rim mount thereby securing the quick connect tire traction system to the tire. A method of installing the quick connect tire traction system on a tire.

The tire traction device is configured for use with a vehicle. The tire traction device attaches to the wheel and tire of the vehicle such that the tire traction device distributes the load delivered through the load path carried by the wheel and tire of the vehicle over a greater surface area than can be provided by the wheel and tire of the vehicle alone. The distribution of the load over this greater surface increases the traction of the wheel and tire of the vehicle on supporting surfaces comprising granular materials. The tire traction device comprises a first stanchion, a second stanchion, a base plate, and a strap. The base plate increases the load distribution of the wheel and tire of the vehicle. The first stanchion, the second stanchion and the strap attach the tire traction device to the wheel and tire of the vehicle.
