Abstract
The utility model relates to a flexible direct drive bogie. Flexibility of a framework is achieved due to the adoption of a flexible beam, and left and right side frames are easy to do nod movement to fit a twist warp with a larger orbit. Due to the realization of the framework flexibility, single stage suspension is simplified to be a very thin layer of rubber blanket, and production cost is reduced. A resilient drive device enables permanent magnet motor to get elastic suspension, meanwhile can transmit torque, transmission efficiency is improved, and the weight of a transmission mechanism is reduced. Traction and braking forces are directly transmitted to a car body instead of being transmitted through a bogie framework, force situation of the bogie framework is optimized, meanwhile the length of a traction rod is not limited by a framework structure, so that the traction rod can be made longer, secondary added stiffness brought by the traction rod is reduced, and riding comfort in a car is improved. Due to the fact that a motor is suspended between wheel sets, wheel base is reduced, the bogie not only can go through a smaller curve but also is provided with a higher critical speed, meanwhile the bogie is provided with good submitting ability to a non-flat line.
