<p>要更好地理解它的工作原理，首先需要了解传动轴是如何工作的。想象一辆基本的车辆，前置发动机和后驱。还要想象这辆车有一个固体后轴，这意味着在经过颠簸时整个轴都会移动。自卸卡车就是这种设置的一个很好的例子。传动轴连接到发动机的旋转部分和安装在后轴上的差速器。当发动机运转时，它会旋转，将机械能传递到需要移动的车轮。下面的动画展示了它是如何工作的。</p>
<p>在传动轴的两端，连接着一个万向节——也称为 u 型接头——允许传动轴移动。它不是从前到后的刚性连接；它适应后轴的运动。</p>
<p>在像科尔维特这样的独立后悬挂车辆上，差速器的运动要小得多。这是因为一些称为半轴的小装置将动力从差速器传递到每个车轮。它们彼此独立移动，而差速器基本保持固定位置。由于不再需要考虑运动，因此可以使用更好的系统。</p>
<p>这个更好的系统就是扭矩管。扭矩管的工作原理类似于传动轴，长管内有一个固定的轴替代它。由于不需要上下移动，能量传递得到了改善。而且由于管道包围着轴，车辆的结构完整性也得到了提高。</p>

<p>由于减少了动力系统的能量损失，使用扭矩管意味着发动机的马力更有效地传递到后轮，从而改善加速。额外的刚性有助于防止汽车在负载下弯曲。当底盘不弯曲时，汽车可以更有效地保持车轮与地面的接触。这些好处大多在赛道上显而易见，值得指出的是，雪佛兰在比赛中使用科尔维特，并且在业余赛车手中很受欢迎。</p>
<p>扭矩管并不是科尔维特独有的。保时捷也使用它们，包括在前置发动机的 944 上。阿斯顿·马丁甚至在其 One-77 超级跑车上使用了这一技术。但尽管在过去的科尔维特中使用过，扭矩管在中置发动机的 C8 版本中并未使用。为什么？简单来说，因为不需要将动力从汽车前部传递到后轴，因为中置发动机位于驾驶员后方，正好在轴上方。这进一步改善了性能，因为汽车的重量现在位于后轮上方。</p>
<p>如果你考虑查看一辆二手科尔维特，较新的中置发动机变体仍然有点贵。稍微旧一点的配备扭矩管的变体则相对实惠，并且能带来 V8 的乐趣。</p>

<p>在科尔维特车型中，扭矩管有效地将动力系统的能量传递到车轮，提高了性能和结构刚性。与传统的传动轴不同，它通过减少能量损失和底盘扭曲来增强操控性。中置发动机的 C8 科尔维特由于其设计将发动机放置在后轴上，因此不使用扭矩管，这进一步提升了性能。扭矩管也被用于其他跑车，如保时捷和阿斯顿·马丁车型</p>

<p>In a vehicle with an internal combustion engine, mechanical processes must work together to take the power the engine produces and transfer that energy to the wheels so the vehicle moves. In many vehicles with a front-mounted engine and rear-wheel drive, a driveshaft sits in the middle of the process, sending power from the engine to the rear of the car. In a Chevy Corvette, General Motors engineers forgo the driveshaft for something called a torque tube. Besides being a tube of torque, what does the torque tube actually do? Why is it preferred in sports car applications like the Corvette?</p>

</div><p>Simply put, the torque tube more efficiently transfers the energy from the drivetrain to the wheels, and it improves structural rigidity. Both of which combine to improve the Corvette's overall performance and handling. At least until the introduction of the eighth generation. The mid-engined C8 version of the car doesn't have them.</p>

</div><p>To better understand how it works, it first helps to understand how a driveshaft works. Imagine a basic vehicle, with a front-mounted engine and rear-wheel drive. Also imagine that this vehicle has a solid rear axle, meaning that the entire axle moves when going over bumps. A dump truck would be a good example of a vehicle with this type of setup. The driveshaft connects to the rotating part of the engine and to the differential mounted on the rear axle. It then spins when the engine is running, transferring the mechanical energy to the wheels that need to move. This animation below shows how it works.</p>

</div><p>At each end of the driveshaft, a universal joint — also called a u-joint — is attached that lets the driveshaft move around. It's not a rigid connection from the front to the rear; it accommodates the movement of the rear axle.</p>
<div class="lb-trans"><p>在传动轴的两端，连接着一个万向节——也称为 u 型接头——允许传动轴移动。它不是从前到后的刚性连接；它适应后轴的运动。</p>
</div><p>On a vehicle with an independent rear suspension, like the Corvette, there is far less movement in the differential. That's because small devices called half-shafts take the power from the differential and transfer it to each wheel. They move independently of each other, with the differential remaining mostly fixed in place. Since the movement doesn't need to be accounted for anymore, a better system can be used.</p>

</div><p>That better system is the torque tube. A torque tube works like a driveshaft, with a fixed shaft inside the long tube replacing it. Since it doesn't need to shift up and down, energy transfer is improved. And with the tube encompassing the shaft, vehicle structural integrity is also increased.</p>

</div><p>With less drivetrain energy loss, using a torque tube means the engine's horsepower is more effectively delivered to the rear wheels, improving acceleration. The extra rigidity helps prevent the car from flexing under load. When the chassis doesn't flex, the car can more effectively keep its wheels on the ground. Most of these benefits are noticeable on a race track, and it's worth pointing out that Chevy races the Corvette, and is popular with amateur racers.</p>

</div><p>Torque tubes aren't exclusive to the Corvette. Porsche uses them, including in the front-engine 944. Aston Martin even used the technology on its One-77 hyper car. But despite it being used in past Corvettes, the torque tube isn't used in the mid-engine C8 version. Why? Simply because there is no need to send power from the front of the car to the rear axle, since the mid-engine sits behind the driver over the axle. This further improves performance since the car's weight is now sitting on top of the rear wheels.</p>
