Abstract: A machine, such as a hauler at a mining site, includes one or more bolted (clamped) joints. Friction coatings are applied to surfaces of two or more materials being clamped to reduce clamp load loss. The friction coatings include one or more coated surfaces and one or more interstitial spaces between the coated surfaces. Various materials may be used as the friction coating including, but not limited to, a tungsten/carbide or stellite/carbide alloy, iron base alloys such as POLYMET alloys, including PMET 290 (an alloy of iron, chromium, boron, manganese, silicone, and nickel), a nickel chromium alloy, e.g., Ni-20Cr, aluminum oxide (Al2O3) particles, and various combinations of these and other suitable materials.

Abstract: A heat exchanger for an exhaust gas recirculation unit is provided. A tube core of the heat exchanger includes a plurality of coolant channels disposed between a plurality of exhaust gas tubes extending from an upstream face to a downstream face. A coolant inlet line and a first coolant outlet line is disposed in a first quarter section of the tube core defined between the upstream face and one fourth of a length of the tube core adjacent to the upstream face. The first coolant outlet line is configured to draw at least a portion of a coolant flow across the upstream face and into the first coolant outlet line. Further, a second coolant outlet line is provided and is configured to discharge a remaining portion of the coolant flow from the plurality of coolant channels that was not drawn out of the first coolant outlet line.

Abstract translation: 提供了一种用于排气再循环单元的热交换器。 热交换器的管芯包括设置在从上游面到下游面延伸的多个排气管之间的多个冷却剂通道。 冷却剂入口管线和第一冷却剂出口管线设置在管芯的第一四分之一部分中，限定在邻近上游面的管芯的上游面和长度的四分之一之间。 第一冷却剂出口管线被配置成将冷却剂流的至少一部分拉过上游面并进入第一冷却剂出口管线。 此外，提供第二冷却剂出口管线并且构造成从未从第一冷却剂出口管线抽出的多个冷却剂通道排出冷却剂流的剩余部分。
