The invention provides a mechanical structure of an electric control hydraulic power-assisted steering gear, relates to the technical field of steering gears, and solves the problems that the original hydraulic power-assisted steering gear cannot meet the requirement and an electric control hydraulic steering gear capable of automatically steering is needed for realizing automatic steering and linear control on a vehicle steering system through whole vehicle network communication; and that a driver requires comfort at present, the requirement for steering portability is higher, and original hydraulic steering cannot completely meet or cannot meet the requirement. The mechanical structure of the electric control hydraulic power-assisted steering gear comprises an electric control input shaft and an electric control device middle body. A hydraulic steering gear is provided with an axially-extending budge supporting column which is in butt joint with the electric control device for radial positioning; a budge is provided with a sealing ring radially sealed with a shell on the lower end surface of and electric control device , so that the radial positioning precision is improved, and meanwhile, a guarantee is provided for butt-joint assembly matching of an internal spline of an output shaft of the electric control device and an external spline of the input shaft of the hydraulic steering gear.
