    摘要: Power transmission for motor-driven vehicles which comprises an input shaft and an output shaft rotatable about a common axis; a gear mechanism including a first planetary gear set having a first sun gear rotatably supported about said common axis, a first ring gear co-axial with and rotatable about said first sun gear and first planetary gear means including first planetary gears engaging the first sun gear and the first ring gear and a first planetary carrier supporting said first planetary gears and rotatable about said common axis; a second planetary gear set having a second sun gear rotatably supported about said common axis, a second ring gear co-axial with and rotatable about said second sun gear and connected with said first sun gear and second planetary gear means including second planetary gears engaging the second sun gear and the second ring gear and a second planetary carrier rotatably supporting said second planetary gears, said second planetary carrier being connected with the first planetary carrier; and a third planetary gear set having a third sun gear rotatably supported about said common axis and connected with said second sun gear, a third ring gear co-axial with and rotatable about said third sun gear and connected with said output shaft, and third planetary gear means including inner third planetary gears engaging the third sun gear, outer third planetary gears engaging the inner third planetary gears and the third ring gear, and a third planetary carrier rotatable about said common axis and rotatably supporting said inner and outer third planetary gears, said third planetary carrier being connected with said first ring gear. Clutch means and brake means are also combined with the gear mechanism so that desired speed changing stages can be obtained through selective actuation thereof.
