日本的NTN公司首创了一种气动轮毂系统,可以便利地实现汽车由4轮驱动(4WD)不停车地转换为2轮驱动(2WD)。使用普通的汽车轮毂在汽车进行4轮驱动向2轮驱动的变换时需要停车。但新型的气动轮毂系统在进行变换时不需要停车。驱动方式的选择只需操纵操纵杆即可,变换由压缩气体完成。除上述优点外,汽车在2轮驱动状态下的驱动噪音也得以大大地减小。 这种新型气动轮毂系统安装在2个恒速联接器的终 Japan’s NTN pioneered a pneumatic wheel hub system that can be conveniently converted from 4WD (4WD) to 2WD without stopping. The use of ordinary car wheels in the car for 4-wheel drive to 2-wheel drive conversion requires parking. However, the new pneumatic hub system does not require parking when it changes. The choice of driving mode can be controlled by the joystick, the conversion is completed by the compressed gas. In addition to the above advantages, the car’s driving noise in 2-wheel drive is also greatly reduced. This new pneumatic hub system is mounted on the end of two constant speed couplings
