汽车转向桥的轮位角包括有:车轮前束、车轮外倾角、转向节主销后倾角、转向节主销内倾角和左右车轮的转向角等五个参数。目前,大多数汽车采用前桥为转向桥,上述参数也就都反映在前桥与前轮上,因而对这些角度也常常习惯的统称谓前轮定位。 Steering angle of the car steering wheel include: the front toe of the wheel, the camber of the wheel, the caster angle of the kingpin, the camber angle of the kingpin and the steering angle of the left and right wheels. At present, most of the cars use the front axle as the steering axle, and the above parameters are also reflected on the front axle and the front wheels. Therefore, these vehicles are often used to the general designation of front wheels.
