Please read the ConMet Service Manual for Steer, Drive, and Trailer Hub Assemblies. It details the recommended maintenance and service for all ConMet wheel ends, including pre-trip inspections, post-trip inspections, and preventative maintenance. 

Yes. PreSet and PreSet Plus hubs are fully serviceable and rebuildable. We also strongly recommend assessing the benefits of replacing the entire hub when service is required. View the reasons why you should replace your hub on our Aftermarket page.

The PreSet spacer is a critical component to the hub design and is needed for PreSet technology to function. The spacer is required to properly space the bearings of a PreSet hub. It is clamped between the two bearing cones with a high spindle nut torque. Using a PreSet or PreSet Plus hub without a PreSet bearing spacer will also render the warranty invalid. Visit the PreSet Plus page for more detailed information about the spacer and PreSet technology.

Not necessarily. There are some other manufacturers that make or have made aluminum hubs. Check for a ConMet logo cast into the hub, or verify the part numbers stamped or cast into the hub using the ConMet App or by reaching out to your local Customer Service representative on our Contact Us page.

会影响。相比于双车轮，单车轮会对轮毂、轴承和轴施加不同负载条件。因此，轮毂负载额定值会根据轮偏置发生变化。如需详细信息，请参见有关“单轮应用中所使用轮毂的轮端负载额定值”的技术公告。

For ConMet wheel ends, refer to the Lubrication chapter of the ConMet Service Manual for Steer, Drive, and Trailer Hub Assemblies. Oil fill volumes for steer and trailer assemblies are dependent on hubcap and spindle dimensions and are shown on the hubcap sight window. For non-ConMet wheel ends, consult your trailer or tractor OEM.

For best performance, ConMet recommends the use of the PreSet Plus spindle nut. However, PreSet hubs do accommodate one-piece spindle nut systems and double nut (jam) systems. ConMet does not recommend a one-piece “castellated” type nut system for use with PreSet hubs. For instructions on proper spindle nut installation, please refer to the ConMet Service Manual for Steer, Drive, and Trailer Hub Assemblies.

No. ConMet PreSet rebuild kits and PreSet Plus spindle nuts should only be used with ConMet PreSet hubs. Only ConMet PreSet hubs are designed to utilize these components and function properly. Use of the kit components or spindle nut in hubs other than ConMet PreSet or PreSet Plus could result in wheel end failure and/or vehicle damage.

所有康迈轮毂的质保范围都位于我们的资源页面上（按轮毂类型列出）。

Some drag is normal for a new seal, but excessive drag or roughness may indicate excessive bearing preload which could result in premature seal failure. An incorrect combination of parts or the use of one or more non-PreSet parts may cause this condition. Please refer to the installation and service instructions in the ConMet Service Manual for Steer, Drive, and Trailer Hub Assemblies.

还有可能是主轴上，特别是油封轴颈上，积累了灰尘或碎屑，这导致油封阻力过大。关于在安装油封和轮毂之前如何准备和清洁主轴的详细说明，您也可以在康迈服务手册中找到。

Yes, according to the ConMet Service Manual for Steer, Drive, and Trailer Hub Assemblies you may convert a hub, but you need to be very vigilant about stud length, drum pilot diameter, and the cap nuts used. For specific instructions and further details, please refer to the Brake and Wheel Installation chapter in the Service Manual.

有关拆卸的详细说明和提示，请参见康迈转向、驱动和挂车轮毂总成服务手册，也可参见名为“从主轴上拆卸冷冻轮毂”的服务公告。
除了外部污染之外，这是正常的微动腐蚀，并且与轴承在使用中对主轴的小幅运动有关。在安装轮毂之前，通过在主轴轴承轴颈上涂上2级润滑脂涂层，可以大大减少微动磨损的影响。在严重情况下，轴承锥将粘附在主轴上，需要一个特殊工具来拆卸轮毂。
在安装轮毂之前，可以用砂布或细砂纸去除多余的锈蚀来修复主轴。如果主轴损坏严重，请咨询您的牵引车或挂车主机厂或轴制造商。

是的！该系统作为Vector eCool™系统的组成部分，可从Carrier Transicold购买。车队现在可以通过Carrier的经销商网络购买，该网络在北美拥有超过200个网店。

The axle is outfit with PreSet Plus eHub technology at each wheel end, capable of generating up to 160 kW peak power. The battery capacity of 45kWh will be replenished by the in-wheel generation as needed. Several large fleets are actively making normal deliveries in trailers equipped with the system and are consistently able to maintain 100% electric TRU mode. These fleets operate a range of different routes, from 1500-mile trips with 2 stops to 120–mile trips with 10 stops.

The system uses a liquid heating and cooling system with a water-glycol solution to keep the eHub™ motors and battery cells at the right operating temperature during use.

Nmotion TR 160-45可以作为TRU的再生电源，通过eTRU上的岸电接口提供电力。由于冷藏挂车中运输的货物（例如食品和药品）价值较高，车队在安装时可以选择保留柴油燃油箱和柴油动力TRU，作为应对这个问题的备用措施。康迈不提供任何柴油技术，也不提供柴油燃油箱。

ConMet manufactures the system at their U.S. facilities. ConMet has received numerous awards from Truck and trailer OEMs for the quality of its products.

The system itself weighs approximately 2,000 pounds. After subtracting the weight of a full diesel fuel tank as well as a TRU generator, we have found that our system is approaching a net zero weight gain if those items were to be removed. For most customers in grocery and foodservice delivery, it is likely you will cube out before this added weight would become an issue.

可以，此系统可以搭配挂车挡泥板使用。

To best run the system, it is important to pre-charge the battery from the grid. For this, the Nmotion system uses a shore power 480V 3–phase and 30A input, already available at many distribution centers. If power is not available at the dock or in the yard, the Nmotion system will be able to generate power while on the road to replace the missing grid power, thus providing customers with a flexible power product as they are building up their infrastructure at their facilities.  

Yes, the ConMet power source is eligible for certain grants, such as with EPA’s DERA Replacement program that can cover up to 25% of the full trailer and system costs.

Routine pre-trip checks for any signs of damage or early wear. Coolant fluid change and regular intervals. Otherwise, there is not any additional maintenance needed. The system is modular, so you can perform normal wheel end, brake and tire maintenance without needing high-volt experience or expertise. The regenerative braking process also reduces the use of friction brakes, extending friction surface life.

The system components are pretested as a kit at ConMet’s factory before shipping. Dealer’s will then be responsible for the final outfitting to a trailer. To facilitate this work, ConMet works upfront with trailer OEM partners so that the trailer can be pre-ordered from the factory with ConMet’s required options for easy installation.

TruckWings在达到高速行驶速度时自动展开，以缩小牵引车和挂车之间的间隙，使得空气速度下降并减少下游湍流。驾驶室后部压力会增加，这可减少牵引车挂车的整体阻力 - 尤其是在强侧风环境中，从而提高燃油效率并减少碳排放。

康迈TruckWings会提供性能报告和正常运行时间监控，这些数据都直接从卡车中提取并发送到云端，然后交付给车队进行审查和分析。

系统平均重量为240磅。

TruckWings可以完整装运 - 只需将适配器支架铆接到驾驶室上，然后将整个系统安装到支架上。如由改装中心或经销商安装，从开始到完成的总用时不超过两小时。

不会，TruckWings的展开和收回操作已完全实现自动化 - 无需司机采取任何操作，即可在每次出行时节省燃油费用。

肯沃斯、福莱纳、万国、沃尔沃、皮特比尔特和麦克的大部分带有完整空气动力学整流罩封装和水平排气管的8级牵引车都在支持范围之内。

通过使用卡车自带的辅助压缩空气系统来驱动三个由中央定向阀控制的气动缸，可以为TruckWings提供动力。

安装在卡车CAN数据链路上的TruckWings控制器可以提供实时速度信息，以便确定卡车是否达到了高速行驶速度，以及展开TruckWings是否安全。智能远距传感器会扫描TruckWings后方区域，确保有足够空间可以安全展开。

面板由玻璃纤维增强聚丙烯制成。因为这种材料轻便耐用，所以其在挂车车身内部和其他空气动力技术中应用十分广泛。框架采用5052航空级铝制成，并使用8级防腐蚀螺栓固定在一起。它通过用于造船、卡车、客运巴士和挂车行业的高强度铝铆钉固定在驾驶室后方。

车队已在加拿大和美国的多个冬季中，在风雪和结冰情况下针对TruckWings完成了超过7亿英里的道路测试。我们在所有紧固件上应用与卡车底盘相同的耐腐蚀锌铝镀层。符合ISO 15552要求的执行器能够在-30ºF下运行，并抵抗牵引车安全操作限制范围内的所有风载荷。它们经历了10年加速寿命测试，以确保能在产品使用寿命内正常运行。
