MoComp Bogies SF30 Bogie for low floor tramcars The bogie SF 30 is in service for the low floor tram Combino plus as well as for the Astra Imperio and also in some Chinese cities. Bogie for 100 % low floor tram with continuous floor height In opposition to the original Combino concept, the Combino plus bogies are in the center of the car body modules which requires a rotating angle of app. 4,5°. The floor height of 350 mm above TOR throughout the whole length of the car, however, remains the same for the new concept. Proven spring concept The transmission of longitudinal forces is realized via a longitudinal rod containing two rubber bushes. The secondary suspension is performed by 4 rubber springs (hourglass springs), which allow a higher lateral movement than steel coil springs. For primary suspension, the same conical rubber springs as for the original bogie design are applied. Stub axles allow low floor without ramps. Outboard longitudinal traction units The motor bogies with the outboard longitudinal traction units have small unsprung mass and a low center of gravity compared with other 100% low floor bogies. The motor bogie is equipped with completely suspended traction drive units with self-ventilated three-phase asynchronous motors. Easy maintenance The traction drive units are equipped with spring-loaded brakes, with the brake disc directly arranged on the motor shaft. This allows an easy access to all major traction and brake components. As a result, nearly all maintenance work can usually be performed without the need for a pit. The complete traction drive units can even be removed and installed without having to lift the vehicle or remove the bogies.
