Power Transmission Systems - Homework 1 Vehicle data to be used is given below: Ready to drive Mass (incl. Driver) [kg] 1240 Max. Engine Torque Mmax [Nm] 200 Gear box Trans missi Gearb Axle ox Trans ratio missioo n ratio on ratio - first gear 1₁ 3,8 2.8 second gear 1₂ 4,4 Tire 195 65 R 15 V A. Determine the dimensions of the clutch friction plate. That means: Determine the inner and outer diameters of the friction plate and determine the maximum normal force on the friction plate. B. After dimensioning, determine the engage times and engage works for both the first and second gears. Additional data: fR = 0.0 (tire rolling resistance coeff.), p = 0.0 (grade), n = 0.9 (transmission efficiency), 2₁ = 1.4,2₂1.2, (the effect of rotational masses on acceleration resistance) Mclutch = Mengine and nengine as the speed of the engine at the beginning of engagement: 1000 rpm Important: For heat calculations take the engine torque value as : "the required engine torque while travelling very slow and with constant speed on a hill (direction uphill) with %18 grade." Determine this torque first, and then use this value in your calculations. Power Transmission Systems - Homework 1 Vehicle data to be used is given below: Ready to drive Mass (incl.
