| 49 | FRICTION SHOCK ABSORBER | US15779728 | 2017-01-20 | US20180355947A1 | 2018-12-13 | Aleh Nicolaevich Halavach |
| The invention relates to the field of vehicle engineering and concerns friction shock absorbers for vehicles, primarily rolling stock. The aim of the invention is to increase the reliability and operating efficiency of a friction shock absorber. The present friction shock absorber (FIG. 3) comprises a housing (1), having a bottom (4) and a neck (2), which is formed by the walls (3) of the housing, said neck having disposed therein a return and retaining device (5) which can be compressed and which contacts with a friction assembly (7) consisting of a pressure wedge (10) and stay wedges (11) in contact therewith. In the neck (2) of the housing (1) there are arranged guide plates (12), which are in contact with the stay wedges (11) as well as with movable plates (13), the latter being in contact with the walls (3) of the housing (1) and being provided with protuberances (9), between which are disposed the guide plates (12), which are mounted on internal protuberances (20) in the housing (1). The surfaces of the guide plates (12) facing the stay wedges (11) have recesses (V) provided therealong, which encompass the return and retaining device (5). | ||||||

| A coupler pivot. A coupler (10) comprises at least a first gimbal (31; 32) defining a pivot that is secured to a mounting (41) for securing to a frame member of a vehicle, the pivot also being secured to a buffer column (39) part of which protrudes on an opposite side of the pivot to the mounting (41) such that the buffer column (39) is moveable relative to the mounting (41) with at least two degrees of freedom.The buffer column (39) defines a free (42) end that is remote from the mounting (41) and that is securable to a further member. The buffer column (39) also includes both a reversible buffer that attenuates buff and draft forces acting between the free end (42) and the mounting (41) and also a non-reversible buffer that attenuates buff forces acting between the free end (42) and the mounting (41) and attaining or exceeding a predetermined energy threshold, the reversible and non-reversible buffers overlapping over at least part of their lengths in the buffer column (39) which in turn overlaps at least one of the pivots. | ||||||

| A friction/elastomeric pad draft gear to cushion and absorb impacting forces on a railroad car coupler system. The friction/elastomeric pad draft gear includes a housing with a closed end and an open opposite end with a major axis extending therebetween. The open opposite end is provided with inwardly tapered extended internal friction surfaces. A wedge is mounted for axial movement in the open end of said housing and friction devices are positioned within the housing between the wedge and the extended internal friction surfaces. A spring seat is positioned adjacent the friction devices and on top of the elastomeric pad stack. The friction devices engagement with the wedge: forms a first selected angle of about 35 degrees null3 degrees; forms a second selected angle of about 2.25 degrees, null about 0.25 degrees, with the extended tapered internal friction surface; and forms a third selected angle of about 90 degrees, null4 degrees, with the spring seat, all in respect to the major axis. | ||||||

| An improved draft gear for transmitting draft forces in railway vehicles. The invention includes a housing with a closed end and an open opposite end provided with a tapered internal friction surface. A wedge is mounted for axial movement in the open end of the housing and friction shoes are positioned within the housing between the wedge and adjacent portions of the internal friction surface. A follower member is positioned adjacent the friction shoes and springs are positioned between the closed end of the housing and the follower member to urge the follower member against the shoes. Each of the shoes has a beveled outer surface in engagement with a beveled inner surface of the wedge, the beveled inner and outer surfaces being formed at a first selected angle with respect to the axis of the housing. Each of the shoes also has a beveled inner face in engagement with a beveled outer face of the follower member, the beveled inner and outer faces being formed at a second selected angle with respect to the axis of the housing. The angle of the bevel on the outer faces of the follower thereby assists in the assembly of the draft gear. The surface area of each of the inner faces is at least equal to the surface area of the engaged outer face of the follower member such that during application of force to the draft gear, the inner face traverses the entire surface of the outer face to prevent accumulation of metal at the interface of the inner and outer faces. | ||||||

| An arrangement for resilient absorption of forces, particularly for an intermediate buffer coupling of rail vehicles, comprises an elongated housing having open and closed ends, a friction element located in the region of the open end of the housing, a resilient element cooperating in series with the friction element and formed as a friction spring including a plurality of inner conical rings and a plurality of outer conical rings cooperating with one another with interposition of lubricant, outer and inner cup-shaped casing members located in the housing and closeably accommodating the friction spring. The outer cup-shaped member forms a support for one end of the friction spring, whereas the inner cup-shaped member forms a support for the other end of the friction spring. A sealing element is fitted on the outer cup-shaped member and held on the inner cup-shaped member so that the outer and inner cup-shaped members can move relative to one another in a direction of elongation of the housing, but at the same time are sealed by the sealing element. | ||||||
| 54 | Friction spring unit | US44548 | 1979-06-01 | US4262887A | 1981-04-21 | Harry Jansen |
| A friction spring unit has a friction spring including a plurality of inner rings and outer rings whose conical surfaces cooperate with each other with interposition of a lubricant, and an outer casing element and an inner casing element which shield the friction spring from outside and inside, respectively. The rings of the friction spring which are located at axial ends of the latter are sealingly connected with the inner casing element and the outer casing element. This sealing connection may be performed by interengaging beads and grooves, or flange-like projections and supports. The casing elements may be formed as hoses or each may be composed of at least two telescopable sleeves. | ||||||

| A shock absorber for absorbing shocks incident to high velocity impact including a cylindrical housing having a tapered bore formed axially therein. A metering rod is slidably positioned longitudinally within the housing having end portions extending therebeyond with one of the end portions connectable to the movable object. An enlarged piston is formed on that portion of the metering rod which is contained within the housing bore. A high viscosity fluid medium, such as Duxseal, fills the chamber defined by the housing bore.
