前桥 后桥和中央差速器 Footage 3m26 in Camellia Café - CAR DIFFERENTIAL 科技系列

已经发过照片展示过差速器,这次通过短片介绍一下汽车差速器。


汽车转弯时,外侧车轮的运行距离要大于内侧车轮的运行距离,因此需要保证外侧车轮的转速高于内侧车轮。

Car Differential is necessary when the vehicle turns, making wheels that are traveling around the outside of the turning curve roll farther and faster than the others.

差速器是一套齿轮系统,包括3组运动轴,其中推力轴的角速度是两个输出轴的角速度的平均值。

A gear train with three shafts that has the property that the angular velocity of one shaft is the average of the angular velocities of the others or a fixed multiple of that average.



发动机的输出扭矩通过推力轴传递到冠状齿轮,冠状齿轮带动旋转壳转动。

Input torque is applied to the Crown Wheel (Gear), which turns the Rotating Cage. 

旋转壳通过行星齿轮间接连接到太阳齿轮,注意不是直接驱动。

The Rotating Cage is connected to both Larger Gears (Sun Gears) only through  Small Gears (Planet Gears).

Torque is transmitted to the Sun Gears through Planet Gears. 

当左右两侧的车轮阻力相等时,行星齿轮仅随旋转壳旋转,但不自转,左右两侧的车轮(太阳齿轮)转速相同。

If the resistance at both wheels is equal, such as two wheels have no obstacle on their own trails or when the car is running straightly, the Planet Gear revolves without spinning about its own axis, and both wheels turn at the same rate.

当左右两侧中的车轮阻力不相等时,行星齿轮不仅随旋转壳旋转,同时还发生自转,左右两侧的车轮(太阳齿轮)转速不同,但一侧速度降低的数值等于另一侧速度升高的数值。

If the Inner Sun Gear encounters resistance, Planet Gears spin as well as revolving, allowing the Inner Sun Gear to slow down, with an equal speeding up of the Outer Sun Gear.

前轮的差速器称为前桥差速器;后轮的差速器称为后桥差速器。

There are Front Differential and Rear Differential.

4驱车还安装有中央差速器,以实现:当前轮所在的路况与后轮所在的路况不同时,实现前轮的速度和后轮的速度不同。

Central Differential is also necessary for All Wheels Drive car when turning on dry pavement, allowing front wheels to rotate at a different speed than the rear wheels.

当汽车某个车轮或多个车轮打滑时,差速器的优势会变为劣势,因此需要采用差速锁,在后续的Footage 3m 26s 中,Camellia Café 将向您呈现差速锁

Differential Locking is designed to overcome the chief limitation of a standard open differential by essentially "locking" both wheels on an axle together as if on a common shaft.

    AWD和4WD不同的,4wd可以不带中央差速,AWD是带中央差速的。记得是这样
