摘要： A diaphragm-clamping arrangement, in which a spring washer having a frusto-conical shape is employed between the outer periphery of the diaphragm and one of the plate members between which the diaphragm is secured. In the free state of the spring washer, the spring washer height is greater than the space between the diaphragm and one plate member so that, when the plate members are joined together, the spring washer is compressed to thereby exert a clamping force on the diaphragm. The diaphragm-clamping point can be provided by either the inner or outer periphery of the spring washer, depending upon whether the frusto-conical shape is concave or convex. By forming an annular recess in the plate member with which the spring is engageable, proper location of the spring washer is facilitated during assembly, and subsequently maintained during clamping.

摘要： A single-cylinder, truck-mounted brake assembly for a railway car truck in which low-cost, light-weight, truss-type brake beams are employed, with one beam having an expansible brake actuator in the form of an air bag mounted thereon. The brake rigging arrangement employs an equalizing lever that is pivotally-connected to each brake beam at its centrally-located strut bar, and force-transmitting members between the respective ends of the equalizing levers, so that the force of the brake actuator is transferred from the brake beam strut bar to the brake shoes via the beam tension member. Accordingly, the light-weight, low-cost brake beams are not subjected to such bending forces as would otherwise require a stronger beam. The single-cylinder air bag arrangement is made possible by utilizing a slack adjuster device as the one force-transmitting member.

摘要： A truss-type brake beam having a bent configuration in which the compression and tension members are bent on opposite sides of a strut member, so that the compression and tension member segments lie in separate planes that intersect to form an angle therebetween, the line of intersection being rectilinear. The bent configuration of the brake beam accommodates housing of a brake-cylinder in the pocket between the compression and tension members adjacent the strut member, facilitates passage of force-transmitting rods between the companion brake beams of a given truck, and permits application of brake beam actuating forces without imparting torque moments to the beam.

摘要： A pneumatic brake cylinder device employs a pair of different sized fluid motors, the pressure chambers of which serve as air storage reservoirs. The cylinder of the larger fluid motor is formed by the main casting and contains a larger piston, while the cylinder of the smaller fluid motor is mounted to the main casting in coaxial relationship with the larger cylinder and contains a smaller piston having an elongated hollow body that is connected at its open end to one side of the larger piston to form a pressure chamber therebetween. The smaller piston fits within the smaller cylinder in spaced-apart relationship therewith to form a pressure chamber delimited by a seal fixed on the main casting for engagement with the piston periphery at any point along its longitudinal axis. The larger piston cooperates with the larger cylinder to form pressure chambers on opposite sides thereof.The arrangement provides for a design employing fewer seals and a simplified main casting in which all the passages to the respective pressure chambers are contained.

摘要： A combined brake cylinder/air reservoir device in which a relatively small, tubular-shaped piston in a positioning chamber is connected to a larger power piston having an application chamber on one side and a release chamber on the other side in which air is stored in place of separate reservoirs. A replaceable cylinder liner is provided to receive different-sized power pistons. During a brake application, the power piston enters the cylinder liner and is displaced from the liner during brake release to provide free air flow between the application and release chambers and thereby facilitate piston return movement by means of a return spring. A dynamic pressure seal between the application chamber and positioning chamber engages the outer periphery of the tubular-shaped small piston, while a smaller diameter dynamic pressure seal between the release chamber and atmosphere engages the inner periphery of the tubular-shaped small piston. This permits the seals to be located longitudinally in the same general area by nesting them, one within the other, thereby permitting the piston stroke to be increased without greatly increasing the longitudinal dimension of the cylinder/reservoir device.

摘要： A single-cylinder, truck-mounted brake assembly for a railway vehicle truck in which low-cost, lightweight, truss-type brake beams are employed, with one beam having the single brake cylinder mounted thereon. Force-transfer levers pivotally-mounted to the respective brake beams at the beam-midpoint are interconnected by force-transmitting members that pass through openings in the bolster to move the brake beams into brake shoe/wheel engagement when a brake application is made. The brake rigging is set up so that the transfer lever bail imparted to the force-transmitting members is split. With respect to the force-transfer lever connected to the one force-transmitting member (brake cylinder), this has the effect of the brake cylinder piston skewing equally on opposite sides of the cylinder centerline to prevent piston seal leakage. In addition, diagonally-opposed lever arms of the respective force-transfer levers are greater in length than the other lever arms to obtain brake force multiplication without unbalancing the brake shoe forces. A further advantage found by making the one transfer lever arm longer than the corresponding lever arm of the other transfer lever is to split the lateral swing of the other force-transmitting member (slack adjuster) equally on opposite sides of the centerline of the bolster opening to avoid interference therebetween.

摘要： A unitized railcar brake equipment can have a relatively small, integrated air supply and can be controlled electronically. The equipment can have a brake cylinder portion and a control valve portion. The brake cylinder portion can have a brake cylinder housing a piston head with a rod end of the piston connected to a railcar brake member. A pair of air chambers communicate on opposite sides of the piston head and an air reservoir can be integral with the brake cylinder housing. Selective coupling of the air chambers and the air reservoir to each other, a source of pressure, or to the atmosphere can be controlled by appropriate valves to control the pressure in the brake cylinder.

摘要： A grade speed control system and method for a railway freight vehicle can include a microprocessor receiving input from, for example, the dynamic and independent brakes on the locomotive, and the brakes on each rail car. The microprocessor can store values for desired train speed and actual train speed as well as constants and equations for converting raw data to derive brake cylinder pressure adjustments for implementing train speed control functions. The grade speed control system can also include communicate with brake cylinder control devices on articulated rail cars to increase or decrease the brake cylinder pressures to control the train speed. If actual speed differs from target speed by more than a predetermined amount, a target acceleration can be calculated and brake cylinder pressures adjustments can be derived to achieve the target acceleration to bring the actual speed of the train to the target speed in a reasonably brief time period. This sequence can be reiterated as the train progresses down the grade, automatically adjusting train braking effort as required to maintain the target speed within a tight range.
摘要翻译： 用于铁路货车的等级速度控制系统和方法可以包括从例如机车上的动态和独立制动器输入的微处理器以及每个轨道车辆上的制动器。 微处理器可以存储所需列车速度和实际列车速度的值，以及用于转换原始数据以导出用于实施列车速度控制功能的制动气缸压力调整的常数和方程。 等级速度控制系统还可以包括与铰接轨道车辆上的制动缸控制装置通信，以增加或减少制动缸压力以控制列车速度。 如果实际速度与目标速度不同，则可以计算出目标加速度，并且可以得出制动气缸压力调整，以实现目标加速度，使得列车的实际速度在相当短的时间内达到目标速度 期。 随着列车进度下降，可根据需要自动调整列车制动力，以将目标速度保持在一个很窄的范围内。

摘要： An brake application solenoid valve arrangement for use in an electronic freight train brake control system on a railway car. Such braking system having a brake pipe normally charged with fluid at a certain pressure, separate compartment auxiliary and emergency reservoirs charged at certain pressures with fluid from the brake pipe and a fluid pressure activated brake cylinder device. Flow of pressurized fluid from the separate auxiliary and emergency reservoirs can be selectively supplied concurrently to the brake cylinder device via the single brake application valve. Backflow check valves between each reservoir and the brake application valve prevent the transfer of pressurized fluid between the reservoirs. The electronic controller can operate the application valve to control the braking and release functions responsive to electrical command signals. A pneumatic control valve can also be operatively incorporated into the brake control system.
