Description Twin engine design concept solves the problem of unable to maximize single speed and torque Because torque can overlap but speed is not good Advantages of a three speed transmission with two engines 1 The power consumption of the two speed three speed transmission will be less than or greater than A single small high speed torque motor depends on the large gear ratio configuration for torque amplification The engine needs to do more work that is more energy consumption 2 Three speed design structure can meet the following terrain requirements The first gear is suitable for the base shape in terrain The second gear is suitable for wet roads with high speed and torque The third gear is suitable for flat metal on off road surfaces 3 The interior design of the 3 boxes is based on durability Gears and shafts are in a critical configuration The gear module is 1 and the gear thickness is 6 5 8 MM This material combines 45 steel and 416 stainless steel 40 CR alloy steel with a variety of materials to ensure the tolerance of the gear case The choice of boxed screws is Taiwan Fangsheng 4 Four gear ratios are designed to meet the needs of more customized games The gear ratio of the transmission can be as high as 1 5 3 There are three interchangeable gears 19 19 T 17 22 T 15 24 T The minimum value can be 1 3 3 The gear ratio of the first and second gears in the gear case is 25 13 T 22 16 T 18 20 T and gear case gear 19 9T The outer material of
