P-gear parking locking device

The utility model discloses a P-gear parking locking device which comprises a shell, a motor, a first-stage transmission large gear, a rotating shaft, a first-stage transmission small gear, a second-stage transmission large gear, an angle sensor connecting shaft, an angle sensor and an output shaft. The first-stage transmission bull gear is driven to rotate, the first-stage transmission bull gear drives the second-stage transmission bull gear to rotate at the same angular speed through the rotating shaft, then the second-stage transmission bull gear drives the output shaft, and a P-gear structure of the vehicle is controlled to be locked. The problems that in the prior art, a traditional parking locking system is large in occupied space, not compact enough and high in price are solved. 本实用新型公开了一种P档驻车锁止装置，包括：壳体、电机、一级传动大齿轮、转动轴、一级传动小齿轮、二级传动大齿轮、角度传感器连接轴、角度传感器、输出轴，通过角度传感器获取外部的控制信号，通过控制信号控制电机的转动，驱动一级传动大齿轮转动，一级传动大齿轮通过转动轴带动二级传动大齿轮按照同样的角速度转动，然后由二级传动大齿轮带动输出轴，控制车辆的P档结构锁止，本申请结构紧凑，用小型电机及更紧凑的减速方案，以解决现有技术中传统的驻车锁止系统占地空间较大，不够
