The servo pressure control unit comprises a motor, a piston, an oil path block and a cylinder body, a shell of the motor is fixedly connected to the oil path block, an output shaft of the motor drives a spiral transmission mechanism in a rotating mode through a planetary gear transmission mechanism, a through hole is formed in an oil path, and the piston is arranged in the through hole in a sliding mode. A cylinder body with an inner cavity is installed at the end, away from the motor, of the manifold block in a sealed mode, the inner cavity communicates with the through hole, the spiral transmission mechanism is in transmission connection with the piston and drives the piston to move in the through hole, a rotating bearing is arranged at the end, close to the motor, of the spiral transmission mechanism, and an inner ring of the rotating bearing is connected with the spiral transmission mechanism. An outer ring of the cylinder body is fixedly connected to one end of the oil path block, and an oil inlet hole and an oil outlet hole formed in the cylinder body are correspondingly communicated with an oil inlet channel and an oil outlet channel in the oil path block respectively. The cylinder body is arranged at one end of the oil path block, the internal space of the oil path block is shared with the cylinder body, the axial size of equipment is shortened, and the cost is reduced.

    本发明公开了一种线控制动用伺服压力控制单元,包括电机、活塞、油路块和缸体,电机的外壳固定连接在油路块上,电机的输出轴通过行星齿轮传动机构旋转驱动螺旋传动机构,油路内设有通孔,通孔内滑动设置有活塞,油路块远离电机的一端密封安装有具有内腔的缸体,内腔与通孔连通,螺旋传动机构与活塞传动连接并驱动其在通孔内移动,螺旋传动机构靠近电机的一端的端部上设有旋转轴承,旋转轴承的内圈与螺旋传动机构连接,其外圈固定连接在油路块的一端上,缸体上设置的进油孔和出油孔分别对应连通油路块上的进油道和出油道。本申请通过缸体设置在油路块一端上,利用油路块内部的空间与缸体共用,缩短了设备的轴向尺寸,降低了成本。
