RTHZ 22 Bogie for 1000 mm Gauge Wagons

Product Overview

This bogie is designed for operation on the 1000 mm railway gauge.

It is suitable for both new‑built wagons and wagon maintenance and overhaul.

Key characteristics

• The axle load is 20 t, with a maximum operating speed of 100 km/h.
• The bogie comprises wheelsets, axle boxes, suspension system, bogie frame, foundation brake rigging, and load‑proportional devices.
• The bogie frame is of welded construction, featuring high structural rigidity and low unsprung mass.
• The adoption of a spherical pivot bearing increases the contact area between the bogie and car body,ensuring uniform load distribution and enhanced longitudinal and transverse force transmission capacity.
• A two‑stage stiffness spring suspension is applied to improve the vertical running stability of empty wagons,thereby achieving excellent dynamic performance for both tare and laden conditions.
