Abstract
A bogie assembly for a rail vehicle comprises a bogie frame, two wheel axles supporting the bogie frame, a primary of a linear induction motor and two motor mounts. The two motor mounts are located proximate a different extremity of the primary and support the linear induction motor underneath the bogie frame. Each one of the two motor mounts has a bogie interface, a motor interface, a first spring, a conical spring, a core pin and a nut. The first spring is connected to the bogie interface on the bogie side while the conical spring is connected to the same bogie interface on the motor side. The core pin extends sequentially from the motor interface through the conical spring, then through the bogie interface and finally through the first spring where it is held in place by the nut on the other side of the first spring.
