摩托车的转向功能是由骑乘者通过操纵它的转向系统来实现的。如图1所示,摩托车的转向系统主要由车把、转向柱、前减振器、车轮及轴承等零部件构成。转向柱通过轴承固定在车架的前立管内,并能自由回转。前减振器与转向柱通过联板固定在一起,车轮、前制动器等零部件固定在前减振器上,车把固定在上联板(减振器)或转向柱上。在行驶过程中,骑乘者通过转动车把,使车轮转过一定角度,从而改变行驶方向。 The steering function of the motorcycle is achieved by the rider by steering its steering system. Shown in Figure 1, the motorcycle steering system mainly by the handlebar, steering column, front shock absorber, wheels and bearings and other components. Steering column through the bearing fixed in the frame before the riser, and can freely rotate. The front shock absorber and steering column are fixed together by a coupling plate, the front parts of the wheel and the front brake are fixed on the front shock absorber, and the handlebar is fixed on the upper plate (shock absorber) or the steering column. During driving, the rider changes the direction of travel by turning the handlebars, turning the wheel a certain angle.
