The invention provides a lightweight bogie frame for a subway engineering vehicle. The lightweight bogie frame comprises a bogie frame body which is an H-shaped structure formed by splicing and welding fish-bellied side beams and a box type cross beam. Damper mounting bases are fixedly connected to the end parts of the side beams. Detector mounting bases are fixedly connected to the end parts of the damper mounting bases. Flange lubricator mounting bases are fixed on the upper ends of the side beams and are close to the inner side. The lower ends of the side beams are provided with axle box joint bases. The upper ends of the joint parts of the side beams and the cross beam are equipped with lower side bearing bases, and the lower ends of the joint parts of the side beams and the cross beam are provided with unit brake mounting bases. The middle part of the upper end of the cross beam is fixed with a lower base board of a spherical center plate. The side parts of the cross beam are fixedly connected with pull bar bases. The side beams and the cross beam are all made of high-strength alloy steel plates with a thickness no greater than 12 mm. The lightweight bogie frame disclosed by the invention is light in weight, simple and reasonable in structure, and comprehensive in function. On the premise of meeting general bogie frame requirements, the lightweight bogie frame also satisfies mounting requirements of various railway track inspection equipment, and represents an innovation of bogie frame forms.
