Auto CVT transmission and mechanical model

· Rp still reached 258.7N and 1034.7N the money. Therefore,[link widoczny dla zalogowanych], in a certain ratio and engine speed range, the impact of the metal with the centrifugal force is still quite large. Auto CVT transmission and mechanical model / Di Jiantao Design - alum study of the work area with 3 metal mechanical analysis [1,2], the pulleys are described by the limits of force and torque transmission pulley relations,[link widoczny dla zalogowanych], taking into account the effect of centrifugal force,[link widoczny dla zalogowanych], after the trend remains the same, when the pulley to limit torque transmission, the small radius arc gone quiet on the pulley, pulley drive I reached the critical state. In this paper, Ma Ⅱ a as a tool of the metal ring tone and metal extrusion thrust calculation, select a small radius of the pulleys does not exist static arc, 4O0o3750 as 3500 salt female 3250 as 3O0oZ wilt such as \, metal with rain (a) i = 2 force distribution when the metal ring, '. Reached the limits of the state of the torque analysis,[link widoczny dla zalogowanych], the parameters used were: metal belt length L = 633mm; pulley center distance of La = 148.5mm; friction coefficient and mean of 0.1; ratio of 0.5 and 2 ; set speed = 4000r/min. Pulley at the entrance to take the initiative to start a metal band (the abscissa is zero) as shown in Figure 6 is a metal ring with a circumference direction of tension distribution of metal and metal extrusion thrust situation. Mrs Z such as' /. 2O0o15oo wilt 100o \_ √ Hun (b) i = O. 5 metal rings force distribution \ 094.2234.85302.95491.356330188.4255. . 5397.15491.35633 metal metal band with Hun Hun (c) _2 force distribution when the metal (d) i = O. 5 pieces of metal by the force distribution in Figure 6 the direction of the metal with the circumference of the metal ring tension distribution and distribution of metal versus 4 Conclusion extrusion thrust force, clamping force will result in larger,[link widoczny dla zalogowanych], unnecessary power loss, so consider the effect of centrifugal force have a positive effect. (1) Metal gear ratio changes with the tension ring; (2) metal thrust belt in the whole of the metal is not always present. With the drive tEi different metal thrust areas and crowded 0 also changes the maximum thrust; (3) According to formula (7), (13) and (16), we can see the metal ring and metal centrifugal force generated by the impact of axial force are negative; (4) speed and speed ratio in a certain situation, without considering centrifugal
