The invention relates to the technical field of vehicle braking, and discloses a locking power mechanism and a parking locking device.The locking power mechanism comprises a shell, a locking driving piece, a driving piece and a locking device, the locking input part is connected to the output end of the locking driving part, and the locking driving part can drive the locking input part to rotate; the locking output assembly is in transmission connection with the locking input piece, and the locking output assembly can push the brake pad to move under the driving of the locking driving piece; the self-locking assembly comprises a fixed ratchet disc, a floating ratchet disc and a self-locking driving structure, the fixed ratchet disc is fixed to the locking input piece, the floating ratchet disc can float up and down under the action of the self-locking driving structure so as to be selectively meshed with the fixed ratchet disc, and the shell abuts against the periphery of the floating ratchet disc so as to prevent the floating ratchet disc from rotating or moving in the horizontal direction. The locking power mechanism applies self-locking force through the shell, the situation that the automobile breaks away from the parking state due to misoperation of a driver is avoided, and the locking power mechanism has the advantages of being simple in structure, low in cost, low in installation difficulty and high in reliability.

    本发明涉及车辆制动技术领域,公开锁止动力机构和驻车锁止装置,锁止动力机构包括壳体以及设于壳体内的:锁止驱动件;锁止输入件,连接于锁止驱动件的输出端,锁止驱动件能够带动锁止输入件旋转;锁止输出组件,与锁止输入件传动连接,锁止输出组件能够在锁止驱动件的带动下抵推刹车片移动;自锁组件,包括固定棘盘、浮动棘盘和自锁驱动结构,固定棘盘固定于锁止输入件,浮动棘盘能够在自锁驱动结构的作用下上下浮动以选择性啮合于固定棘盘,壳体抵接于浮动棘盘的周部以阻止浮动棘盘在水平方向上旋转或移动。锁止动力机构利用壳体施加自锁力,避免因驾驶员误操作而导致汽车脱离驻车状态,具有结构简单、成本低、安装难度低以及可靠性高的优势。
