The invention relates to a pressure servo control unit applied to an integrated intelligent brake system, and belongs to the field of automobile brake-by-wire systems. Comprising a centripetal thrust bearing, a ball screw, a connecting screw, a motor hollow shaft, a motor shell, a motor stator, a motor winding, motor magnetic steel, a deep groove ball bearing, a motor BUSBAR, a connector, a motor front end cover, an angle sensor MPS rotor, an angle sensor MPS induction PCBA, a screw anti-rotation piece, a large valve block, a piston and a cylinder body. The motor direct-drive ball screw has the advantages that the mechanical transmission efficiency is improved, a speed reducing and torque increasing mechanism is omitted, a noise source with the highest system level is eliminated, the noise vibration intensity (NVH) performance of the system is good, the motor rotor assembly and the ball screw assembly are of a self-centering structure design, and clamping stagnation of the piston is avoided.
本发明涉及一种应用于集成智能制动系统的压力伺服控制单元,属于汽车线控制动系统领域。包括向心推力轴承、滚珠丝杠、连接螺钉、电机空心轴、电机外壳、电机定子及绕组、电机磁钢、深沟球轴承、电机BUSBAR和连接器、电机前端盖、角度传感器MPS转子、角度传感器MPS感应PCBA、丝杠防转件、大阀块、活塞和缸体。优点在于电机直驱滚珠丝杠既提高了机械传动效率,据此取消了减速增扭机构,消除了一个系统级别最高噪音源,系统声振度NVH性能优良,电机转子组件及滚珠丝杠组件为自定心对中结构设计,避免了活塞卡滞。
