5T Traveling Device Integrated Wheel Set Assembly Leaf Spring Suspension for Mining Locomotive

5T traveling device is a complete undercarriage assembly engineered for 5-ton electric locomotives, integrating a precision-machined wheel set, a two-stage reduction gearbox, and a heavy-duty leaf spring suspension into one compact unit. Designed to withstand the abrasive dust, moisture, and continuous vibration of underground rail haulage, this assembly delivers reliable traction, effective shock absorption, and long service life in demanding industrial environments.

Manufacturing & Engineering Process

The traveling device is manufactured through a series of precision processes: high-strength alloy steel billets are forged and normalized to relieve internal stresses; wheel blanks are CNC-machined to the Φ520 mm rolling circle diameter and flange profile; gear components are cut on precision hobbing machines, then carburized and hardened to achieve high surface hardness while maintaining a tough core; the gearbox housing is cast and precision-machined for perfect bearing bore alignment; the leaf springs are formed from high-grade spring steel, heat-treated, and shot-peened for maximum fatigue life; all components are assembled with heavy-duty bearings, seals, and lubricated for long-term operation; the completed assembly undergoes run-in testing to verify smooth rotation, proper gear meshing, and leak-free sealing.
