根据汽车设计理论,汽车转向机构的设计,应使汽车在转向过程中所有的车轮都处于纯滚动而无滑动状态,以减小汽车转向时的阻力,并减少轮胎磨损,也有利于增加汽车转弯时的稳定性。对于两轴汽车要满足这一要求,若每个车轮的轮胎都不产生偏离,则内外轮转角应有下列关系(如图1所示) ctgθ_o-ctgθ_i=DE-OF/BE=K/L……(1) 式中:θ_o——外轮转角θ_i——内轮转角L——轴距L——两轴销中心线延长线到地面交点之间的离距
According to the theory of automobile design, the steering mechanism of the car should be designed so that all the wheels of the car are in a pure rolling and non-sliding state during the steering, so as to reduce the resistance when the vehicle turns and reduce the tire wear, and also increase the turning of the car When the stability. For two-axle vehicles to meet this requirement, if the tire of each wheel does not produce deviation, the inner and outer wheel angle should have the following relationship (as shown in Figure 1) ctgθ_o-ctgθ_i = DE-OF / BE = K / L ... (1) Where: θ_o - outer wheel angle θ_i - inner wheel angle L - wheelbase L - the two pin axis extension line to the intersection of the distance between the ground
