PURPOSE:To simplify the construction of a speed change gear and make it with smaller size and weight by controlling a V-belt type stepless speed change gear and a reverse gear couple correlatively. CONSTITUTION:While a sleeve 52 is held at the shutting position as shown in the illustration and a specified oil pressure is being applied to oil pressure chambers 26, 36 of a stepless speed-change gear 18, power of the drive shaft 2 is transmitted to the driven shaft 4 through the stepless speed-change gear 18 to turn it in the same direction as the drive shaft 2. During this time, the car is in the position of running forward. In order to move the car backward, the V-belt 16 is put in slip condition as well as the sleeve 52 is shifted to the connective position, in which the sleeve 52 rides over spline shafts 48, 50. |
