Definitions
- the present invention relates to a primary suspension of railway vehicles, between a bogie chassis and an axle comprising two axle boxes, this suspension comprising, for each axle box, a lever oscillating around a horizontal shaft integral with said chassis, said lever having a first branch supported on a suspension element connected to said chassis and a second branch opposite the first with respect to said shaft.
- the object of the present invention is to produce a primary suspension, the suspension elements of which are only subjected to vertical forces.
- the primary suspension according to the invention is thus characterized in that it comprises two articulated connecting rods each connecting an axle box and the bogie chassis, the second branch of a lever resting on a box via 'an elastic element.
- Another object of the present invention is to provide a primary suspension requiring only a small footprint and placed so as to leave a large space for the body suspension and its travel.
- the axis of the suspension elements is therefore in a vertical plane and disposed in an inclined manner relative to the vertical.
- a preferred embodiment of the suspension is described below, with reference to the single sheet attached, which represents a partial view, in elevation.
- axle box 1 connected to the bogie chassis 2 by a servo rod 3 articulated to the chassis by an elastic articulation 4.
- An elastic element 7 is interposed between the axle box and the part 5B of the lever 5 located on the side of the axle box.
- the elastic element is for example an elastomer block.
- the suspension element is advantageously a spring or more coaxial springs.
- the axis 10A of the spring 10 is located in a vertical plane and disposed in an inclined manner with the lower part of the spring on the side of the wheel 8, so that the lever frees up all the space necessary for the vertical and horizontal deflections of a pneumatic suspension 11 of large load capacity body.
- the angle of inclination relative to the vertical is close to 45 degrees.
- the two branches 5A and 5B of the lever form an angle between them between 120 and 160 degrees to ensure plane support of the branches on the respective elastic elements.
- control rod 3 and its articulation 4 provides lateral guidance of the axle, and the lever 5 and its bearing 6 are only interested in vertical forces. .
- the length L of the chassis beam is considerably reduced and can allow easy manufacture, particularly when this beam is molded.
- Lever 5 can easily be made from high-characteristic steel or any other modern material.
