Problems solved by technology

Each of the four primary suspensions is placed at each wheel between the axle and the chassis of the bogie, which constitutes a complex structure and has a large mass
Therefore, one of the challenges in the bogie field is to reduce the weight of the bogie and make the bogie structurally simpler

Embodiment Construction

[0024] In the description, the terms "vertical" and "horizontal" are defined for a bogie mounted in a railway vehicle and placed on the railway. Likewise, the horizontal plane is generally parallel to the plane in which the axles lie, and the vertical plane is generally parallel to the plane in which the wheels lie. The term "longitudinal" is defined with respect to a direction of a railway vehicle in a horizontal plane, and the term "transversal" is defined in terms of a direction in a horizontal plane that is substantially perpendicular to the longitudinal direction.

[0025] see figure 1 and 2 A bogie 1 of a railway vehicle (not shown), such as a subway, tram or train, is described. The bogies are used in known manner to be coupled to the carriages (not shown) of the railway vehicle.

[0026] The bogie 1 comprises two axles 2 , 3 , a chassis 4 , two main suspensions 6 , 7 , an elastic articulation 8 and a transmission 10 .

Abstract

The invention provides a bogie (1) used for railway vehicles having two pairs of wheels (12, 13, 14, 15). The wheels (12, 13, 14, 15) are connected by the aid of connection devices (18, 20) so as to form axles (2, 3). The axles (2, 3) are connected by the aid of a chassis (4). Each of the axles (2, 3) is hinged to the chassis (4) around the axis (C-C') generally parallel to the axles (2, 3). The bogie is characterized in that it comprises two main suspension devices (6, 7); each main suspension device (6, 7) is connected to the corresponding axle (2, 3) and is connected to an elastic hinge piece (8) so as to form the suspension of the chassis (4) relative to the axles (2, 3).

Description

technical field [0001] The invention relates to a bogie for railway vehicles, of the type comprising two pairs of wheels, the wheels of a pair of wheels being interconnected by means of connecting means to form an axle, said axles being interconnected by means of a chassis, each The axle is articulated to the chassis about an axis that is generally parallel to the axis of the axle. [0002] The invention also relates to a railway vehicle comprising such a bogie. Background technique [0003] Bogies of the aforementioned type are known. However, such bogies generally comprise four main suspensions enabling the chassis of the bogie to be suspended relative to the axles and two slave suspensions enabling the carriage of the vehicle to be suspended relative to the axles. Chassis suspension of the bogie. Each of the four main suspensions is placed at each wheel between the axle and the chassis of the bogie, which constitutes a complex structure and has a large mass. [0004] ...
