The invention relates to the technical field of steering gears, in particular to a hydraulic steering gear integrated with an active steering damper, which comprises a steering gear shell with a hollow accommodating cavity; the rack is arranged in the steering gear shell in a penetrating mode and can move in the axial direction of the steering gear shell. The partition plate is arranged on the steering gear shell and located in the containing cavity; the boosting piston is fixedly arranged on the rack in a sleeving mode and located in the boosting cavity; the vibration reduction piston is fixedly arranged on the rack in a sleeving mode and located in the vibration reduction cavity, and a first circulation hole is formed in the vibration reduction piston; and the damping assembly is arranged on the vibration reduction piston, and the damping assembly is electrically connected with a speed sensor and an angle sensor of the steering gear. The damping device can be conveniently arranged in a narrow front cabin, the damping force can be actively adjusted, and the requirement for safe driving is met.
