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 hub from which protrudes radially three arms which are extended at the outer end by anti-slip components transversally embracing the tread of the tyre. The inner area of the anti-slip components in contact with the tread is designed to increase friction to prevent circumferential displacement of the anti-skid device. When the car is moving a horizontal depression is formed at tyre-ground contact and this provokes a change in wheel radius. Integrated springs follows the depression by moving radially inwards to ensure that the anti-skid device stays attached to the tyre even when an anti-slip component is at the ground contact point at the bottom of wheel. A fastening handle integrated into the hub secures the device on the wheel by simultaneously tightening the arms radially inwards.

A traction device attachable to a wheel having a rim to which a tire is mounted. The traction device includes first and second gripping elements facing each other, the second gripping element being longitudinally movable between an extended position and a retracted position, the first and second gripping elements being closer to each other in the retracted position than in the extended position. When the traction device is operatively mounted to the wheel with the second gripping element in the retracted position, the traction device extends across the tire thread and the first and second gripping elements grip the wheel therebetween at the rim, and, when the second gripping element is in the extended position, the traction device is removable from the wheel.

A device for self-extraction of a vehicle using a towing rope made in the form of a gripper, including at least three arms arranged circumferentially and having a shape that allows installation on the drive wheel of the vehicle. The device has a traverse with a threaded opening in the center where the threaded rod is installed, at the end of the rod facing the vehicle wheel in the operating position, a hub stop heel is installed. The gripper's arms have two L-shaped parts, the first parts with their side that is oriented along the axis of the device are pivotally installed on the traverse, and the second parts are rigidly connected to the first parts at a section of their sides oriented in the radial direction from the axis of the device.

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.

A system is provided for retractably deploying traction of a wheel. The system includes a set of grippers, each gripper having a cleat and a radially disposed strut. The system further includes a set of first poles, each first pole coupled to one of the struts, the first pole configured to support motion of its corresponding strut between a parked position and an engaged position, wherein, in the engaged position, the corresponding cleat is axially disposed and engaged against the tread of the wheel and, in the parked position, the corresponding cleat is disengaged from the tread of the wheel. The system includes a first faceplate configured to rotate with the wheel. The system further includes a cleat deployment mechanism having a second faceplate rotatably coupled to the first faceplate, and a set of second poles, each second pole coupled to one of the struts and to the second faceplate.
