Auto wheel unidirectional rotating control mechanism

The utility model discloses an auto wheel unidirectional rotating control mechanism, including supporting brake disc and braking pincers, its characteristics lie in, are equipped with a plurality of ratchet teeths on the outer periphery of brake disc to install the pawl on the braking pincers, the front end of pawl towards the ratchet teeth sets up, still installs telescopic machanism on the braking pincers, and telescopic machanism's work terminal surface is to the outer periphery setting of brake disc, the pawl is installed on the connection structure that telescopic machanism work end has,and telescopic machanism stretches out the back, drives the pawl front end and inserts in the ratchet teeth formation and can restrict the draw back pivoted unidirectional rotating cooperation of direction of brake disc. The utility model has the advantages of simple structure the compactness, work safe and reliable, the direction of marching forward that auto wheel can be smooth and easy is rotated. 本实用新型公开了种汽车车轮单向转动控制机构
