Belt type speed change steering device

The utility model discloses a belt type speed change steering device, which comprises a drive belt gear, a driven belt axial wheel, a double-sided gear belt and two idle gears. The drive belt gear is movably installed on one side of the driven belt axial wheel, the two idle gears are vertically symmetrically disposed on the other side of the driven belt axial wheel, and the belt sequentially surrounds the drive belt gear and the two ideal gears through the inner surface, and surrounds the driven belt axial wheel through the outer surface. The belt type speed change steering device is modified in design based a traditional gear change steering device, greatly reduces production cost, simultaneously increases rotating efficiency and working precision of the whole device, increases protection for normally used rigidity while lowering work noise, and releases space limit on the design.
