Deformable Mecanum wheel

The invention belongs to the field of Mecanum wheels, and provides a deformable Mecanum wheel which comprises a Mecanum wheel mechanism, a deformation mechanism and a deformation driving mechanism. One end of the deformation mechanism is mounted on the Mecanum wheel mechanism and can move in the axial direction of the Mecanum wheel; the other end of the deformation mechanism is connected with the deformation driving mechanism, the deformation driving mechanism drives the deformable Mecanum wheels to be switched between the Mecanum wheel mode and the common wheel mode, and the deformation driving mechanism is installed on the chassis mechanism and can drive the deformation mechanism to move. According to the Mecanum wheel, the degree of freedom of lateral movement of the Mecanum wheel can be locked by controlling the position of the friction disc, and the following technical effects are achieved: switching between a Mecanum wheel mode and a common wheel mode can be realized to adapt to different scenes, and th
