Description
Technical Field
The invention belongs to the field of railway vehicle bogie mechanisms, and particularly relates to a non-power bogie of a high-speed motor train unit with a built-in axle box.
Background
The non-power trucks of rail transit vehicles typically include a frame, a primary suspension mechanism, a secondary suspension mechanism, a wheel set mechanism, an axle box mechanism, and a brake mechanism, wherein the primary suspension mechanism typically includes a primary vertical shock absorber and a primary spring, and the secondary suspension mechanism typically includes two air springs, two transverse shock absorbers, two traction links, an anti-roll torsion bar mechanism, and two secondary vertical shock absorbers.
The framework on the bogie is responsible for bearing the weight of the vehicle body and transmitting one of key components of acting force between the wheel rail and the vehicle body; the framework is used for bearing and transmitting force and simultaneously bearing the core tasks of components such as a primary suspension mechanism, a secondary suspension mechanism, a wheel set mechanism, an axle box mechanism, a shaft-mounted brake disc mechanism and the like, so that other components can be well realized, and interference of layout spaces of the components is avoided under certain deflection; the frame must therefore have good strength, rigidity and stability so that the rail transit vehicle can run quickly, flexibly, safely, stably and smoothly along the rail.
The traditional framework is generally in an external axle box form of an axle box mechanism positioned outside a wheel, and a cantilever axle box with a rubber cantilever node is adopted, so that the framework has large volume and heavy weight, has poor adaptability to continuous large-angle torsion road sections of a track line, and the framework has the mass which belongs to the mass among springs, so that the load born by a wheel set and a vehicle body can be increased sharply due to the larger framework weight when the train runs at a high speed, the wheel track is worn greatly, the running maintenance cost is high, and the running stability and the comfort of the vehicle are influenced. Compared with a wide and heavy axle box external framework, the axle box internal framework has the advantages of small volume and light weight, but the side beams of the framework are positioned on the inner sides of two wheel pairs and limited by the inner side distance of the wheel pairs, the transverse space for arranging auxiliary equipment such as a traction center, a braking mechanism and the like is extremely intense, the space for arranging the auxiliary equipment arranged on the framework is compact, the assembly and maintenance are difficult, the assembly space cannot be reserved for newly added functional parts, and the axle box internal framework has weaker bearing capacity on diamond-shaped loads, so that the conventional reduction design is difficult to achieve reasonable balance among larger air spring spacing size, higher structural strength of the framework, better vibration reduction and overall weight of the framework.
For a high-speed motor train unit train with the design speed exceeding 400 km per hour, the stress condition of a bogie frame is more complex, and therefore, due to the consideration of structural strength and safety, the bogie of the existing high-speed motor train unit train adopts an external box type all-welded frame of an axle box, which has the advantages of large size and weight of the whole frame, multiple welding lines, serious welding deformation and poor flexibility. And the axle box built-in framework with small volume and light weight is difficult to be applied to the bogie of the high-speed motor train unit with the design speed exceeding 400 km per hour.

According to the structural design, the anti-rolling torsion bar, the anti-meandering shock absorber and the secondary vertical shock absorber are all migrated from the inside of the framework to the outside of the framework, so that the layout space inside the framework is better released, the assembly and maintenance of the auxiliary components of the framework are convenient, and the assembly space is reserved for newly added functional components. The light-weight integrated mounting seat is formed by integrally machining a light aluminum alloy material through forging and milling processes, and a lightening hole is formed in the middle of the light-weight integrated mounting seat.
