Planetary gears are used mainly in final drives, rear-mounted splitter boxes and, above all, in automatic transmission. The simplest form of planetary gear (the planetary-gear train) consists of sun gear, ring gear and arm with planet gears. Each of the three elements may act as drive, output or may be atrest. Therefore, gear variation is possible as regards the transmission ratio, ranging as far as a reversal of the direction of rotation. The parallel meshing of several gears under load permits a compact construction.
The gear unit has no free bearing forces, allows high torques and power branching, has good efficiency, and input and output are coaxial. Power shifting is possible, since friction-type shifting devices (clutches and brake bands ) can be used.
3.6 Differential
When a vehicle is cornered the inner wheel moves through a shorter distance than the outer wheel. This means that the inner wheel must slow down and the outer wheel must speed up. During this period it is desirable that each driving wheel maintains its driving action. The differential performs these two tasks.
The principle of the bevel type differential can be seen if the unit its considered as two discs and a lever (Fig. 3-19).
When the vehicle is travelling straight, the lever will divide the driving force equally and both discs will move the same amount.
When the vehicle corners, the driving force will still be divided equally but the inner disc will now move through a smaller distance; this will cause the lever to pivot about its center which will prize forward the outer disc to give it a greater movement. This action shows that the torque applied to each driving wheel is always equal-hence the differential is sometimes called a torque equalizer.
3.8 Front-Wheel Drive (FWD)前轮驱动
Many modern cars have front-engine front-drive layouts (Fig. 3-20). Here the engine still mounts at the front of the vehicle. However, the parts do not align exactly as they do in conventional drive lines. The transmission and final drive transmit engine power and torque to the front wheels. Thus, the front wheels“pull”the vehicle along the road. In conventional systems, the rear wheels“push”the vehicle along.
Front-wheel drive has advantages over rear-wheel drive. Because the engine and transmission components in a FWD vehicle are packaged compactly at the front of the car, the use of interior space is more efficient. Thus, a relatively small car can have a reasonable amount of room inside for passengers and luggage. In addition, the weight of the FWD powertrain (engine and transmission) is directly over the driving wheels. This positioning helps to increase traction on slippery surfaces.

行星齿轮传动，主要用在最后，后置式分配器，首先，在自动变速箱。该行星齿轮（行星齿轮火车）最简单的形式由太阳轮，齿圈和行星齿轮机构。这三个元素的每个人都可以作为驱动器，输出或可能atrest。因此，变化是可能的齿轮传动比方面，包括作为旋转方向逆转远。根据负载的几个齿轮啮合允许并行结构紧凑。
减速器轴承部队没有自由，允许高扭矩和功率分支，具有良好的效率，以及输入和输出同轴。电源转换是可能的，因为摩擦型移装置（离合器和刹车带）都可以使用。
3.6微分
当车辆通过狗急跳墙比外轮短距离内轮动作。这意味着，内轮必须放慢和外轮必须加快。在此期间最好是每个驱动轮保持其驾驶行为。差分执行这两项任务。
该伞型微分原理可以看出，如果单位认为其作为两个光盘和一个杆（图3-19）。
当车辆行驶直，杆将动力分成两盘将平等和相同数量的移动。
当车辆弯道，动力仍然平分，但现在进入椎间盘内，通过一个小的距离，这将导致杠杆支点有关其中心将奖金外盘转发给它一个更大的动作。这一行动表明，扭矩适用于每个驱动轮始终是平等的，因此有时也被称为微分扭矩均衡。
3.8前轮驱动（FWD的）前轮驱动
许多现代汽车已经前置引擎前轮驱动的布局（图3-20）。在这里，发动机仍然架在车前。然而，部分不相符，正是因为他们在传统的驱动线路的事。最终传动的传动和发动机的功率和扭矩传递给前轮。于是，前车轮“拉”的车辆在道路沿线。在传统的系统，后轮“推”车沿。
前轮驱动拥有后轮驱动的优势。因为在FWD的车辆的发动机和传动组件被打包在车前紧，室内空间的使用更有效率。因此，一个相对小型车能有乘客和行李空间内的合理费用。此外，对FWD的动力总成（发动机和变速箱）的重量是直接在驱动车轮。这种定位有助于提高在湿滑路面的牵引力。

主要用于行星齿轮箱,rear-mounted最终驱动分配器,最重要的是,在自动变速器。最简单的形式的行星齿轮(planetary-gear列车)由太阳齿轮,齿轮和手臂与行星齿轮。这三个要素可以作为驱动、输出或可能atrest。因此,齿轮变异是可能的,至于传动比,只要逆转的旋转方向。几个齿轮啮合的并行加载允许一个紧凑的结构。
没有免费的齿轮装置,使轴承力高扭矩和电力分支,具有较高的效率,并输入和输出同轴电缆。动力换档是可能的,因为磨擦离合器、制动器移装置(带)都可以使用。
36微分
当一辆走投无路,在穿越短的距离比外轮。这就意味着在必须放慢,必须加快外轮子。在这段时间里,这是合乎情理的每个驱动轮维持它的驾驶行为。这两项任务的微分执行。
这个原理可以看到斜角式差动假如单位及其视为两盘和杠杆。3-19(图)。
当汽车旅行的杠杆分直、动力和阀瓣将同样的相同。
当车辆的角落,驱动力仍然会平分但内在的阀瓣将通过一个较小的距离,这将导致杠杆枢轴关于它的中心,将奖金的外层碟给它一个更大的运动。这个行动表明扭矩对每个驱动轮总是equal-hence鉴别有时被称为力矩平衡。
38前轮驱动装置(FWD前轮驱动)。
许多现代汽车有front-engine front-drive布局(图3-20)。这里的引擎还安装在前面的车。然而,在部分不对齐
