The invention discloses an automobile integrated electro-hydraulic braking system pressure generating device which comprises a ball screw transmission assembly, a main cylinder and a hollow shaft motor, a nut and a lead screw are arranged in the ball screw transmission assembly, and a rotor is fixedly arranged on the lead screw through a bolt and a clamping ring. The rotor is fixedly connected to the surface of a shell of the hollow shaft motor through a bearing and a flange plate, and first buffer rubber is arranged on the surface of the rotor. According to the invention, the first advantage is realized based on the fact that the rotor of the motor is hollow, and a plurality of parts such as the ball screw transmission assembly, the guide sleeve and the piston are located in the center of the motor at the stroke limit position, so that the space is effectively utilized, and the high integration is realized, and the second advantage is realized based on the characteristic of high integration, the rotor and the lead screw are connected together, so that the space is effectively utilized. An additional transmission mechanism is not needed, the lead screw rotates while the motor is powered on and the rotor rotates, and the production efficiency is improved, the cost is reduced and the like without the transmission mechanism.
