Improved service-life, low-profile, retrofittable, elastomeric mounting for three-piece, railroad-car trucks

An improved service-life, low-profile, elastomeric mounting (18) for placement between the side-frame-pedestal-jaw roof (22) and the axle-box or axle-bearing adapter crown (20) on a three-piece, railroad-car truck. The mounting (18) minimizes the damaging compression induced edge strains resulting from the cocking motions imposed on the elastomeric mounting (18) during railroad car braking and rocking. The addition of shims (28), specialized elastomer contouring (40), graded thicknesses (t1; t2) of the elastomeric layers (30, 31) in combination with high shape factor of the elastomeric layers (30, 31) allows the compression induced edge strains to be significantly reduced and results in extended service-life of the elastomeric mounting (18).

Patent CH671930A5

Spring support and method for its manufacture

Suspension system for railway vehicles - has elliptical spring shackles with flattened ends to generate friction to damp out oscillations

A railway vehicle is suspended from its axles by leaf springs. The ends of the springs are attached by shackles (8,9,10) to the vehicle body. The outer shackles (8,9) are generally elliptical in shape and have a mainly circular cross-section. The inner surface of each of the two shackles is in contact with the lower support (14), the central shackle (10) or the upper support (12). It has a localised flat (15) formed on it. The chord forming this flat subtends an angle alpha at the centre of the circular cross-section. If the sine of half the angle alpha is greater than the coefficient of friction, then any swaying motion of the vehicle relative to the axle will be damped by friction and a smoother suspension system will be achieved.

Shaft spring

VEHICLE AXLE SUSPENSION

Suspension d'essieu de véhicule. L'essieu 11 est porté à chaque extrémité par une boîte à essieu 12, reliée au véhicule par un montage 13 de deux ressorts 15 qui flanquent l'essieu. Chaque ressort 15 est formé par empilage alterné de couches 16a en élastomère et d'éléments d'armature 16b. Le centre d'élasticité du montage de ressort est placé en un point 20 intermédiaire entre le milieu 10 de l'essieu et la boîte à essieu 12 associée, ce qui réduit le rayon d'action Ry de la suspension et donc la résistance opposée par les suspensions, en virage, au mouvement décrit par les essieux pour rayonner autour du centre de courbure. Application notamment aux véhicules de chemin de fer. Vehicle axle suspension. The axle 11 is carried at each end by an axle box 12, connected to the vehicle by an assembly 13 of two springs 15 which flank the axle. Each spring 15 is formed by alternating stacking of elastomeric layers 16a and of reinforcing elements 16b. The center of elasticity of the spring assembly is placed at an intermediate point between the middle 10 of the axle and the associated axle box 12, which reduces the radius of action Ry of the suspension and therefore the resistance opposed by the suspensions, in bends, to the movement described by the axles to radiate around the center of curvature. Application in particular to railway vehicles.
