This bogie is a passenger car bogie with two suspension devices, mainly suitable for 1000mm gauge, with a maximum axle load of 14t and a maximum operating speed of 120km/h.

• The wheelset adopts a rotating arm positioning device with a simple structure, achieving elastic positioning of the wheelset; Spiral steel spring is used in the primary system, and air spring is used in the secondary system; The traction device adopts a single pull rod method; The damping system adopts hydraulic dampers; By combining the above technologies, the stability and comfort of vehicle operation can be greatly improved.
• Adopting self sealing structure bearings, maintenance free can be achieved for a long time; The braking system adopts a disc type braking method, which can prolong the service life of the wheels while reducing the generated noise.
• The internal system of the entire bogie does not have friction pairs, and the main connections are modular, reducing daily maintenance costs.

• Q: What gauge and performance parameters is this bogie designed for? A: It is mainly applicable to 1676 mm broad‑gauge lines, with a maximum axle load of 16 t, a maximum operating speed of 120 km/h, and a speed‑up potential of 160 km/h.
• Q: What structural and suspension features improve its dynamic performance? A: It adopts dual‑stage helical spring suspension, pull‑rod wheelset positioning, central pivot traction, hydraulic damping, full side bearings, and an additional stabilizer / anti‑rocking mechanism to enhance stability and ride quality.
• Q: What maintenance and economic advantages does this bogie have? A: It uses self‑sealing maintenance‑free bearings, modular main connections, no internal friction pairs, and disc brakes to reduce wheel wear, noise, and daily maintenance costs
