四轮定位的作用（Four wheel positioning function） Function and effect of four wheel positioning First, what is the four wheel alignment? Four wheel positioning: the steering wheel, steering knuckle and front axle of the automobile have a relative position between the three. This kind of installation with relative position is called steering wheel positioning, also called front wheel positioning. The front wheel positioning includes caster (angle), kingpin inclination (angle), camber (angle) and the front wheel four content. The role of two and four wheel alignment L increase driving safety; L reduces tire wear; When the L is straight, the steering wheel is straight and straight; L turn the steering wheel automatic correction; L increase driving control; L reduces combustion consumption; L reduces the wear of suspension components. Benefits of three or four wheel positioning Four wheel positioning is one of the essential tasks in automobile maintenance. Unless there are obvious problems associated with it before you make the four round, for example, straight line stability is poor, you can feel it immediately after the four round, otherwise you will find it difficult to judge whether you are doing well or not. Due to the current auto repair industry varies greatly, maintenance quality varies greatly, so I suggest you try to better maintenance enterprise maintenance, to ensure the quality of the four wheel positioning, to ensure traffic safety. 1. enhance driving comfort; 2. cut down on gasoline consumption; 3. increase tire life; 4. ensure the stability of the vehicle; 5. reduce the wear of chassis suspension parts; 6. enhance driving safety Four, four wheel positioning of the species Four wheel alignment instrument with toe ruler and optical level positioning, cable positioning, CCD positioning, laser positioning, image positioning and 3D instrument and a wheel positioning device. The 3D, CCD and laser products are currently on the market for three major products, 3D product
