Abstract
The invention relates to a bogie (10) for a high-speed railway vehicle, comprising: a bogie chassis, at least one wheel (20) mounted rotating on the chassis by means of an axle (18) and a primary suspension system (22), at least one motor (24), for each motor (24), at least one gearbox (26) able to mechanically link the motor (24) and the axle (18). Each motor (24) is rigidly fastened to the chassis (12).
Claims13
A bogie for a high-speed railway vehicle, the bogie comprising:
- a bogie chassis,
- at least one wheel mounted rotating on the bogie chassis using an axle and a primary suspension system,
- at least one motor, and
- at least one gearbox for each motor, wherein said at least one gearbox is able to mechanically link the motor and the axle,
- wherein each motor is rigidly fastened to the bogie chassis;
- wherein the bogie chassis comprises two stringers;
- and
- wherein each primary suspension system comprises at least one shock absorber and at least one resilient return element, both said at least one shock absorber and said at least one resilient return element being arranged between the stringer and the axle.
