The invention relates to a novel high-speed motor train unit non-power bogie. The novel high-speed motor train unit non-power bogie comprises a framework, a wheel pair, a primary fastening suspension device, a secondary fastening suspension device, a traction device and a foundation brake device, wherein a crossbeam and side beams of the framework respectively adopt a box-type structure formed by welding steel plates, a main body consists of two side beams and a crossbeam, the crossbeam and each side beam are respectively formed by welding steel plates, the crossbeam and each side beam are respectively provided with various functional seat in a welding manner, the crossbeam and each side beam are connected with each other in a plugging manner, an upper cover plate and a lower cover plate of each side beam extend inwards, a side vertical plate of the crossbeam is directly inserted in the extension position of the upper cover plate and the lower cover plate of the side beam and directly connected with the inner vertical plate of the side beam, the lower cover plates of the crossbeam and each side beam are directly connected with each other in a welding manner, and the upper cover plates of the crossbeam and the side beams are connected in a variable cross section manner by virtue of a transitional connecting block; a small longitudinal beam is welded on the crossbeam, and brake beam is connected with the upper cover plate of the crossbeam and the small longitudinal beam in welding manner. The bogie is simple in structure, so that the application, maintenance and repairing can be facilitated; the modularized and uniform design of parts can be realized, so that the applicability of products can be improved, and the fatigue service life of the bogie can be prolonged.
