1、4WD-4 Wheel Drive system 四轮驱动系统The 4WD system is the driving force of an engine from the 2WD system of two wheel drive to four wheel drive, while the 4WD system are included in the active safety system, mainly 4WD system has more excellent than the efficiency of driving force of 2WD engine, achieve
2、better tire traction play an effective gravity and steering force, so in terms of security 4WD system application, better traction and steering force of gravity caused by tire, good driving stability and tracking, in addition to cross-country this more besides 2WD 4WD system No. 4WD currently can be
3、 broadly divided into short-term (PART TIME 4WD) and full time (FULL TIME 4WD) four wheel drive system, short four wheel drive system according to the driver's demand, the choice of two wheel drive and four wheel drive, the transmission system belongs to compared to traditional 4WD systems, from
4、 a cross-country Perspective, this transmission system when selecting four wheel drive mode before and after the gear connected directly, can ensure that the drive force output before the rear wheel, therefore this system belongs to the 4WD system suitable for cross-country. The other is a full 4WD
5、system, this system does not need the driver's operation, the vehicle is always in the four wheel drive system, this system can be distributed via the front and rear drive force, the optimal configuration can achieve a more perfect tire drive and steering force, which belongs to the high perform
6、ance transmission system, in addition to the configuration from the general cross-country jeep, commonly used in high-performance coupe on the.4WD 系统是将发动机的驱动力从 2WD 系统的二轮传动变为四轮传动 , 而 4WD 系统之所以列入主动安全系统 , 主要是 4WD 系统有比 2WD 更优异的发动机驱动力应用效率 , 达到更好的轮胎牵引力与转向力的有效发挥 , 因此就安全性来说 , 4WD 系统对轮胎牵引力与转向力的更佳应用 , 造成好的行车稳
7、定性以及循迹性 , 除此之外 4WD 系统更有 2WD 所没有的越野性。 4WD 目前大致可分短时 (PART TIME 4WD)及全时 (FULL TIME 4WD)四轮传动系统 , 短时四轮传动系统可依驾驶者的需求 , 选择二轮传动或四轮传动 , 这种传动系统是属于比较传统的 4WD 系统 , 从越野性的观点来看 , 这种传动系统当选择四轮驱动模式时前后轮系直接连结 , 可确保前后轮的驱动力输出 , 因此此种系统系属于适合越野的 4WD 系统。另一种为全时 4WD 系统 , 此种系统不需驾驶人操作 , 车辆总是处于四轮驱动系统 , 此种系统可经由前后驱动力的分配 , 可达到更完美的胎驱动力及转向力的最佳化配置 , 属于高性能传动系统 , 除了配置于一般的越野吉普车外 , 常用于一些高性能的轿跑车上。
