ABSTRACT:
Power transmission device for automobile is disclosed. The power transmission device for automobile comprises a driving shaft (10), an output shaft (30) a transmission (20), a differential gear part (50) and a four-wheel drive part (60). The driving shaft (10) has a plurality of driving gears (12), each of them having a different diameter respectively. The driving shaft (10) is connected to an engine (E). The output shaft (30) is a hollow shaft and outputs power from the driving shaft (10). The transmission (20) has a plurality of speed change gears (22) meshing continuously with the driving gears (12) and also has a brake member braking the speed change gears (22) selectively to transfer power to the output shaft (30). The differential gear part (50) is located at an end portion of the output shaft (30) and controls the amounts of rotation of both right and left front wheels (42). The four-wheel drive part (60) is fixed on the output shaft (30) and transfers power to rear wheels (44) selectively. The power transmission device for automobile controls effectively the amounts of rotation of the wheels and provides a configuration for four-wheel drive device which is simple and compact.
