摘要： A method and a device according to such method for monitoring a railway traction system comprising monitoring means, controlled by a manual or automatic drive system, controlling and coordinating a plurality of individually driven wheels disposed in opposing coaxial pairs on either side of the vehicle. The method comprises, for each pair of coaxial wheels of said plurality, the steps of cyclically measuring representative quantities of the mechanical torque temporarily developed by the motors, comparing such quantities and disconnecting both motors from the electric power supply whenever the result of the comparison shows a difference greater than a previously established value. The method advantageously also comprises, for each motor, the further steps of cyclically memorizing the temporary value of a parameter of the motor, commanding a variation of such parameter by a small pre-established quantity, calculating the value that such controlled parameter should reach as a result of such variation, comparing the result of the calculation with the effective value reached and disconnecting the power supply to the motor whenever the result of such comparison is not equal to or less than a pre-established quantity.
The device according to the method comprises a general monitoring system which through lines of communication (12) communicates with actuating devices (13), one for each motor-driven wheel. The individual actuating device (13) comprises a local monitoring device (14) connected, for the exchange of control and information signals, to a power system (15) operating an electric motor (16) whose driving shaft is connected, by means of a mechanical reduction unit (18), to a traction wheel (19). Moreover, the motor shaft is also kinematically connected to a tachymetric indicator (17), which transmits to the local monitoring device (14) a feedback signal proportional to the speed of the motor.摘要翻译： 雅丁的方法和设备来搜索用于监测铁路牵引系统，其包括监控装置，通过手动或自动驱动系统控制，控制和协调在车辆的任一侧上的相对的同轴对处理完毕单独驱动的车轮的多元性方法。 该方法包括，对于每对所述多个同轴车轮的，循环地测量由马达暂时产生的机械扭矩的代表量，比较检测量和断开都从电力供给电动机的步骤，每当的比较显示了结果 差异超过预先设定的值越大。 该方法有利地所以包括一个用于每个马达，循环地存储所述发动机的参数的暂定值，由一个小的预先建立的量命令的搜索参数的变化，计算所述值还包括以下步骤并搜索受控参数shoulderstand达到如 求的变化，其中达到了有效的值计算的结果进行比较和断开电源到电机每当搜索比较的结果不等于或小于预先设定的量的结果。 该装置gemäß该方法包括：通过通信（12）的哪些线的一般监测系统与致动装置（13），一个用于每个电机驱动的车轮进行通信。 单个操纵装置（13）包括（14）连接的本地监视装置，用于控制和信息信号的交换，对电动机（16）操作动力系统（15），其驱动轴被连接时，通过的手段 机械减速单元（18），到牵引轮（19）。 因此更在电动机轴运动地连接到一个测转速指示器（17），其中发送给本地监测装置（14）正比于电机速度的反馈信号。

摘要： A bogie (10), in particular for railway platform cars, comprising a swinging transom (11) with a rotating central portion connected, by means of a fifth wheel (12), to a body (13) of the vehicle.
The swinging transom (11) has opposite ends (14) generically shaped in the form of an overturned L which each fit over a box-shaped element (16) connected to it by means of suspensions (15).
The two box-shaped elements (16) are connected to each other by a frame (17) laterally surrounding the fifth wheel (12), and each comprising two generically U-shaped arms (18).
Each U-shaped arm (18) carries a wheel (19) independently driven by its own motor (25) and is fitted from above with couplings (20) to connect it to a primary suspension (21) horizontally disposed on the upper surface of the box-shaped elements (16).摘要翻译： 特别是用于铁路平台车辆的转向架（10），包括具有通过第五轮（12）连接到车辆的主体（13）的旋转中心部分的摆动横梁（11）。 摆动艉板（11）的相对端（14）通常形成为翻转的形式，每个都被安装在通过悬架（15）连接到其上的箱形元件（16）上。 两个箱形元件（16）通过横向围绕第五轮（12）的框架（17）彼此连接，并且每个包括两个通用的U形臂（18）。 每个U形臂（18）承载独立由其自身的马达（25）驱动的轮（19），并且从上方装配有联接器（20），以将其连接到水平地设置在 盒形元件（16）。
