[0246] Determine the main parameters as follows: i 1 i 2 = 1.00, i 3 i 4 = 1.00, i mF1 =2.50,i mF2 = 1.50, i mF3 = 1.00, i mF4 =0.75,i mR =-2.00,k 2 = 1.5,k 3 = 2.0.
[0247] Figure 14 Given the relationship between the ratio of output speed to input speed of the transmission and the displacement ratio, the output shaft can be connected to the reduction gear to drive the vehicle.
[0248] O is the origin;
[0249] A(0, 0.24) is the feature point of mechanical gear I, that is, n o =0.24n e ;
[0250] B(0, 0.40) is the feature point of mechanical gear II, that is, n o =0.40n e ;
[0251] C(0, 0.60) is the feature point of the mechanical gear III, that is, n o =0.60n e ;
[0252] D(0, 0.80) is the feature point of mechanical grade IV, that is, n o =0.80n e ;
[0253] E(0, -0.33) is the characteristic point of the mechanical reverse gear, that is, n o =-0.33n e .
[0254] for R 1 (H) Gear position, when e∈[-1.00, 0], n o / n e ∈[-0.40, 0]; for F 1 (H) s...
