One-way rotation control mechanism for automobile wheel

The invention discloses a one-way rotation control mechanism for an automobile wheel. The one-way rotation control mechanism includes a brake disc and a pair of brake calipers which are matched with each other. The one-way rotation control mechanism is characterized in that a plurality of ratchet teeth are arranged on the outer circumferential surface of the brake disc, a pawl is mounted on the pair of brake calipers, the front end of the pawl is arranged towards the ratchet teeth, a telescopic mechanism is further mounted on the pair of brake calipers, the working end of the telescopic mechanism is arranged towards the outer circumferential surface of the brake disc, and the pawl is mounted on a connecting structure which the working end of the telescopic mechanism is provided with. Afterthe telescopic mechanism extends out, the front end of the pawl is driven to be inserted into the ratchet teeth to form a one-way rotation fit capable of limiting the rotation in the receding direction of the brake disc.
