ELECTRONIC PARKING BRAKE MECHANISM

An electronic parking mechanism is disclosed. The electronic parking mechanism comprises a parking cam assembly, a pawl assembly and a parking gear (11); the parking cam assembly comprises a parking guide shaft (6) and a parking cam (2), the parking cam (2) is sleeved on the parking guide shaft (6), and one side of the parking cam (2) is provided with an arc protrusion along a circumferential direction so that as the parking cam (2) rotates, the pawl assembly is in a first position where the pawl assembly parks in the parking gear (11) and a second position where the pawl assembly parks out the parking gear (11), respectively; the pawl assembly comprises a pawl (10) and a pawl shaft (12), an upper part of the pawl (10) can contact the parking cam (2), the pawl shaft (12) is provided on a side of the pawl (10), and the pawl (10) can rotate around the (12). The present disclosure provides a novel electronic parking mechanism, which can realize flexible contact and flexible drive. Moreover, when the parking motor is powered off, the parking mechanism can also be mechanically unlocked in the cab, which has high safety and good operation comfort.
