Problems solved by technology

[0007] In addition, the traditional four-wheel drive device for transmitting power to the front and rear wheels is relatively complicated in structure and cannot effectively realize multi-speed shifting operation
That is to say, the four-wheel drive device of the prior art is installed at one part of the transmission device, and the device for selectively connecting the transmission device to the four-wheel drive device is relatively complicated in structure, so it is impossible to change output speed

Embodiment Construction

[0016] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

[0017] Fig. 1 is a schematic diagram showing the structure of a preferred embodiment of the power transmission device of the present invention.

[0018] As shown in FIG. 1 , the power transmission device of the present invention is connected to a propeller shaft 10 of an engine E, a transmission 20 , a differential gear member 50 , a four-wheel drive gear 60 and an output shaft 30 .

[0019] The driving gears 12 are mounted on the transmission shaft 10 and have different diameters, respectively. The transmission 20 includes a plurality of transmission gears 22 that are continuously meshed with the drive gear 12 and a braking member 70 that selectively brakes the transmission gears 22 .

[0020] The propeller shaft 10, the transmission 20 and the braking member 70 will be schematically described as they are disclosed in US Patent Application No. 09 / 47661...

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 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.

Description

technical field [0001] The present invention relates to a power transmission device for an automobile, and more particularly, to a power transmission device that can efficiently drive front and rear wheels through the operation of a gearbox having a plurality of planetary gears. Background technique [0002] Cars have a power transmission that sends engine power to the front or rear wheels. [0003] In general, a power transmission device is composed of a clutch, a transmission, a differential gear, and the like. A clutch connects two working parts together so that they can be engaged or disengaged at will without stopping both parts. A gearbox is a complete system of gears used to change the speed from that of an input shaft to that of an output shaft, or to change the direction of rotation of a shaft with or without a speed change. A differential is a gear arrangement that allows one drive wheel of a car to go faster than the other drive wheels when the car is driving ar...
