Claims

[Scope of utility model registration request]

A hydraulic torque converter has an input rotating member and an output rotating member configured to rotate around the same axis, and an input shaft and an output shaft at one end are arranged on the same axis as the rotational axis of the output rotating member. a planetary gear type transmission which is concentrically connected, the input shaft is drivingly connected to the output rotating member, and selectively achieves a plurality of gears according to engagement switching of a frictional engagement device; first and second counter shafts arranged in parallel; a power transmission device that transmits the rotational power of the output shaft to the second and second countershafts, respectively; and a power transmission device that transmits the rotational power of the first countershaft a differential gear device that transmits rotational power to the front wheel axle; a rear wheel axle drive shaft that transmits rotational power to the rear wheel axle; and a clutch that selectively drives and connects the second counter shaft and the rear wheel axle drive shaft. A four-wheel drive automatic transmission characterized by having the following features:
