The invention discloses a three-axle welding bogie and a railway vehicle. The three-axle welding bogie comprises a framework assembly, a suspension vibration reduction system, a foundation braking device and a weighing device. The framework assembly is connected with the wheel set assembly through the suspension vibration reduction systems and the axle box assembly, and the suspension vibration reduction systems are of double-side Leynolds vibration reduction structures and are located on the two sides of the axle box assembly respectively. A load balancing device is connected between every two adjacent suspension damping systems, and the top of each load balancing device is connected with the bottom of a side beam of the framework assembly. The weighing device is installed on a side beam of the framework assembly and connected with the suspension vibration reduction system through a load conversion base. The basic braking device adopts a double-side brake shoe braking device; according to the axle box round spring suspension vibration reduction system, the vibration reduction performance of the bogie is improved, the curve trafficability of the bogie is improved, and meanwhile the weighing function is achieved.
