Attention should also be paid to the lock-in ratio, and urban areas with high lock-in ratios are not suitable

LSD can also be divided into different types of locking rates. The way of distinguishing can also be distinguished from the shape of the cam hole. The higher the angle is, the higher the locking rate is. At this time, the initial torque of the LSD operation is lower, that is, there is a slight difference in wheel speed between the two wheels. It will be locked to make the two wheels rotate synchronously; on the contrary, the lower the locking rate, the higher the allowable value of LSD for the difference in wheel speed between the left and right wheels. The locking rate can be from 15 degrees to 65 degrees. It is recommended to use a setting of 15~35 degrees for a tail-swing car and a street car. This is because if a general street car uses an LSD with a high locking rate, when turning at a low speed or reversing into the garage, the left and right tires will be easily locked. There is a difference in the rotation speed, and the driver needs to constantly replenish the oil to make the inner wheel make a idling sound of “brushing, brushing, brushing”, so that the vehicle can turn smoothly, making driving more difficult, losing the convenience of daily use, and accelerating tire wear. Speed, so unless you really love self-challenging mountain roads, or even a tail flick, don’t try LSD with a high lock rate easily.

Regarding the principle and application skills of mechanical LSD, it is not comparable to the advancement of drive technology. Take Audi Quattro four-wheel drive system as an example. Through high-speed computing computer, rudder angle/G value/wheel speed sensor, and electronic hydraulic pressure Drive friction disc type LSD, there is no so-called difference in way or locking rate, you can lock how you want to lock。
