Abstract: 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.
