This is a two-axle bogie dedicated for metro vehicles operating on 1435 mm standard‑gauge tracks, available in motor and trailer variants. Both variants feature a compact layout and excellent dynamic performance.

• The bogie frame is an H‑shaped welded assembly consisting of box‑section side frames and seamless steel tube crossbeams, offering high rigidity and structural integrity.
• The suspension system comprises rubber‑stack primary springs and air spring secondary suspension; this dual‑stage elastic suspension effectively isolates vibration and delivers exceptional ride comfort.
• Motor bogies are equipped with three‑phase AC traction motors and gearboxes to transmit driving power. A combination of center pivot plus Z‑shaped traction rods is adopted to transfer traction and braking forces between the bogie and carbody.
• Each bogie is fitted with four tread brake units, two of which are integrated with spring brake actuators to fulfill the parking brake function.
• Selected trailer bogies are additionally equipped with ATP antennas for train control and protection.

• Q1: What gauge and vehicle type is this bogie intended for?
  A: It is a two‑axle bogie for metro vehicles, designed for 1435 mm standard‑gauge lines, with motor and trailer versions.

• Q2: What are the key structural and suspension features?
  A: It uses an H‑shaped welded frame with box‑section side beams and seamless steel tube crossbeams; dual‑stage suspension with rubber‑stack primary springs and air spring secondary suspension.

• Q3: How are traction, braking and safety functions realized?
  A: Traction and braking forces are transmitted via center pivot and Z‑shaped draw‑bars; four tread brake units per bogie with spring brakes for parking; selected trailer bogies are fitted with ATP antennas.
