    • Silencing equipment is provided for an air-cooling assembly in a large off-road vehicle having wheels, traction motors for the wheels that operate in a motoring mode to propel the vehicle and a power generating dynamic braking mode, resistor grids for dissipating the dynamic braking power, and a blower for moving cooling air past the grids to cool them. The silencing equipment may include a resistor grid housing 24 and at least one upper inlet 22 for passing cooling air to the interior of the housing. The inlet includes noise-absorbing material. A conduit 28 is provided for directing cooling air from the upper inlet through a transition chamber to reach the blower and at least one resistor grid in the housing. The conduit is lined with noise-absorbing material. A removable cover 30 is provided for the conduit for accessing the air blower in the housing through the transition chamber, whereby servicing of the blower may be performed without removal of the entire upper inlet. In another aspect, the silencing equipment includes at least one outlet 31 for exhausting air from the resistor grid housing. This outlet includes a plurality of exhaust vanes positioned at an angle relative to a stream of exhaust air to impart a deflection to the exhaust air into a desired direction. The plurality of exhaust vanes includes noise-adsorbing material whereby this one outlet combines air deflection and silencing in a single device.
    • 为具有轮子的大型越野车辆提供了一种空气冷却组件的沉没设备,用于车轮的牵引电动机,以驾驶模式运行,以推动车辆和发电动力制动模式,用于消除动态制动的电阻器网格 电源和用于使冷却空气通过电网的鼓风机以使其冷却。 消音设备可以包括电阻器栅格壳体24和用于将冷却空气传递到壳体内部的至少一个上部入口22。 入口包括吸声材料。 导管28用于将来自上部入口的冷却空气引导通过过渡室以到达鼓风机和壳体中的至少一个电阻器格栅。 导管内衬有吸音材料。 为导管提供可拆卸盖30,用于通过过渡室进入壳体中的鼓风机,从而可以在不去除整个上部入口的情况下执行送风机的维修。 在另一方面,消音设备包括至少一个用于从电阻器栅格壳体排出空气的出口31。 该出口包括多个排气叶片,该排气叶片相对于废气流成一定角度,以将废气偏转到期望的方向。 多个排气叶片包括噪声吸附材料,由此该一个出口将空气偏转和消音结合在一个装置中。
