LSD-限滑差速器技术解析limited slip differential

LSD-限滑差速器技术解析limited slip differential Limited Slip Differential limited slip differential, LSD is a loop tracking control can ensure the driving wheel dynamic Force output, the rear axle differential is commonly used in the rear wheel drive car, the four round of the central differential and rear axle differential drive the car on,

LSD's purpose is to improve the traditional differential when the driving wheel as the force output is too large or the ground is too slippery, or single wheel suspension

Caused by the unilateral driving wheel slippage, caused another round of also losing the driving force, to make the vehicle can not rescue or tracking of

Good phenomenon. LSD control mode is the most commonly used is called a VLSD-Viscous LSD viscous limited slip differential and its practice Usually in the differential with the viscous coupling metal piece, and is provided with a heat is easy to expansion and stable oil, when the car

A happening slippage of the drive wheel and left

and right wheel speed difference between the large, will make are respectively connected with the left and right driving wheel on the sheet metal of

Raw speed difference, the metal sheet of the speed difference will make the oil to produce high temperature expansion, so will make the rounds of the speed difference is limited,

The original part of the

driving force and to transfer to another wheel pulley, which makes the original driving force of the wheels to regain power lose,

To improve the driving stability and off-road performance, senior luxury car, this system is most commonly used to rear wheel drive, and the cross country four

Wheel drive.

力输出, 常用于后轮驱动车的后轴差速器上, 四轮驱动车的中央差速器及后轴差速器上,

LSD的目的乃在于改善传统差速当驱动轮由于驱动力输出太大或地面太湿滑, 或单轮悬空

所造成单边驱动轮打滑, 而造成另一轮也同时失去驱动力, 至使车辆无

法脱困或循迹性不

好的现象。LSD最常用的控制方式是一种叫VLSD-Viscous LSD 黏性限滑差速器, 其作法

通常是在差速器中设有黏性藕合金属片, 及装有一种遇热很容易膨涨且稳定的油类, 当车

辆发生驱动轮打滑且左右轮的转速相差大时, 将使分别连结于左右驱动轮上的金属片亦产

生转速差, 此金属片

的转速差将会使油产生高温膨涨, 如此将会使两轮的转速差受到限制,

而将部份原本传到打滑轮的驱动力转移到另一轮, 使得原本失去驱动力的轮子重获力量,

改善行驶的稳定性及越野性能, 此种系统最常用于后轮驱动的高级豪华房车, 以及越野四

轮传动车。
