The invention discloses an implementing mechanism of a vehicle electronic parking brake system. The invention comprises a transmission device and a brake clipping caliper assembly. After the output ofthe direct current motor in the transmission device is performed with speed reduction and torque increase via a synchronization belt transmission device and a involute few tooth difference planetarytransmission device, the rotation motion is transferred into a straight line motion through a sliding helical transmission mechanism, and a braking disc is braked through the method that a piston anda braking block assembly are pushed by a screw sleeve. The circumferential freedom degree of the piston is limited by the braking block assembly, and the circumferential and the racial freedom degreesof the screw sleeve are respectively limited by a piston non-round hole and a blocking ring. The screw sleeve and a screw rod adopt self locking thread matching, to guarantee the parking braking to be secure and reliable. Compared with the implementing mechanism of the traditional vehicle rear wheel parking braking system, the invention has the advantages that the driving cab space is saved, thelabor intensity of the driver is reduced, the parting braking is more secure and reliable, and the invention is convenient for adopting intelligent control and integrating other functions.
