    1516743 Axle-bearing guiding arrangements FRANZ PLASSER BAHNBAUMASCHINENINDUSTRIE GmbH 30 Oct 1975 [6 Dec 1974] 44889/75 Heading B7L A suspension system of a rail vehicle comprises two helical springs 7 and a hydraulic damper 10 which are disposed to act between an axle bearing 5 and a chassis 1 (or bogie frame), the springs 6 being located fore and aft of the bearing 5 between an axle bearing easing 6 and a yoke 8 which is pivotally supported by shackle suspension 9 on frame parts 15 depending from the chassis 1. Shackles 18 of the suspension 9 are mounted on the yoke 8 and parts 15 by bolts 16 which act as torsion bars. Vertical guides 11 within the springs 7 comprise mushroom-shaped projections 12 from the casing 6 received in guide parts 13 mounted on the yoke 8 to provide telescopic guidance while permitting some relative tilting of the parts 12, 13. As shown, shoe brakes 14 are provided and the damper 10 is pivotally mounted on a housing of the bearing 5. Where disc brakes are employed, the damper is pivotally mounted on a carrier plate (22) for the prake pads, Fig. 6 (not shown). The running gear is particularly for use in twin-axle or multiaxle permanent way machines for laying, removing or maintaining the permanent way, and is intended to provide spring suspension and damping in vertical, longitudinal and transverse directions.

    one
    The invention relates to railway transport and concerns the construction of a spring suspension of rolling stock and, in particular, of track machines for the repair of the upper 5 Railway track.
    There is a known spring suspension of a track machine, containing coil springs JUn and hydraulic oscillation dampers 13 installed between axle cases of axle boxes and trolley frame.
    However, this spring suspension is not suitable for work in the track machines used in the repair of the upper structure of the railway track.
    The purpose of the invention is to improve road performance by ensuring that the load on the axles is equalized with the maximum bend of the spring suspension under conditions of drastically varying axle loads and vehicle speeds.
    For this purpose, the suspension is provided with a transverse spring flap, 25
    in the form of a traverse, supported by helical springs, made with a number of mounting holes and connected to the ends by means of hinged hangers with the frame of the trolley.
    In addition, each screw spring is provided with a vertical mushroom shaped guide resting on the housing of the axle box.
    At the same time, hydraulic oscillation dampers are pivotally connected at one end to the axle box body.
    FIG. 1 schematically shows a trolley with a proposed spring suspension, general view; in fig. 2 same, view from the axis of the railway track; in fig. the position of the suspension elements during its operation.

    The suspension contains between the frame 1 of the carriage and the case of the axle box 2 of the wheelset 3 helical springs k and a hydraulic vibration damper 5. In addition, the suspension is equipped with a transverse spring plate, made in the form of a cross member 6, provided with a number of mounting holes, which is connected by means of hinged suspensions 7 with the frame of the carriage and is supported on the case of the axle box 2 by means of coil springs. Inside each helical spring there are vertical guides 8 of the mushroom shape, which help reduce the size displacement of the wheelset along and across the axis of the track. If, due to defects in the track or due to the undulating position of the rails, a vehicle transport means occurs, frame 1 moves relative to wheel 3 across the axis of the track by the amount Z. This causes the suspension 7 to deflect relative to the elements 9 of the cart frame and also to spring traverse 6. In addition, the coil springs k are also loaded at an angle and with a bend. In this case, the vertical direction 8 prevents the total lateral movement from being perceived by the spring k and, consequently, the load on the spring is reduced. When the brakes are sharp, during movement, the frame 1 of the carriage moves in the direction along the axis of the track and is displaced relative to the wheel by the width of the rotor 6 by the X. In this case, the spring to the plane is set obliquely so that the suspension 7 turns around the hinges 10, as a result of which k unloads, and the other is overloaded, which not only leads to damping of the movement, but also causes a reaction force on traverse 6, contributes to its return to the initial position, i.e. parallel to the plane of the path. In the event that the trolley frame moves relative to the wheelset in the vertical direction by the value Y, this movement is damped 9 64 mainly by the vibration damper 5 and also by the joint force of the coil springs C, In the course of the trolley movement, almost all of the above movements X, Y, Z and for their damping all elements of the spring suspension work simultaneously in accordance with the described procedure. nymi schemes. Claim 1. Suspension suspension of a traveling machine, containing helical springs and hydraulic vibration dampers installed between the hulls of wheel pairs and the trolley frame, characterized in that, in order to improve ride quality by ensuring alignment with the axle with the greatest deflection of the spring suspension under conditions of drastically varying axle loads and speeds of movement, it is equipped with a transverse spring plate, made in the form of a cross member, supported by helical springs, made with a set of paid-holes and the associated ends by means of articulated suspension to the trolley frame.
