Embodiment Construction

[0015] Figure 1-5 One embodiment of the invention is shown. figure 1 The transfer device 2 is shown in . The transfer device 2 is connected to a transmission (not shown) on a power source internal combustion engine, which is generally arranged longitudinally and near the front of a four-wheel drive vehicle (not shown). The transfer device 2 supports the input shaft 6 in the transfer case or housing 4 via an input shaft bearing 8 . The front end of the input shaft 6 is connected to an output shaft (not shown) of a transmission (not shown). On the other end of the input shaft 6, that is, the rear end, a first gear 10 for changing speed is fixed (formed integrally in this example). The gear 10 is part of a speed change mechanism for converting the rotational motion of the input shaft 6 into high and low speed motions, as explained hereinafter.

[0016] In the transfer case 4 , a countershaft 12 is supported by bearings 18 so as to be parallel to the input shaft 6 . The coun...

Abstract

A transfer arrangement for a four-wheel drive vehicle having an input shaft, a transmission, and a center differential. The transmission includes a first gear attached to the input shaft, a first counter gear attached to a countershaft in parallel with the input shaft to receive the rotation of the first gear, a second counter gear fixed to the countershaft and rotating therewith, and a second gear aligned with the input shaft and rotatably supported along the input shaft to receive the rotation of the second counter gear. High speed-side and low speed-side output parts are attached to the first and second gears respectively. The center differential is disposed between the high speed-side and low speed-side output parts. An engaging device disposed adjacent the center differential selectively engages with the high speed-side and low speed-side output parts.

Description

technical field [0001] The invention relates to a transfer device for a four-wheel drive vehicle. In particular, the present invention relates to such a transfer device for a four-wheel drive vehicle that eliminates the space occupied by a hub dedicated to the variator and a connecting shaft connected between the variator and the center differential. space to reduce the axial length of the transfer device. Background technique [0002] A four-wheel drive vehicle is equipped with a transmission for converting the driving force of the internal combustion engine, and a transfer device for distributing power or driving force input from the transmission to two output shafts. Some 4WD vehicles are equipped with a center differential that allows the two output shafts to turn at different speeds. [0003] Some examples of four-wheel drive vehicles of the above type are shown in Japanese Patent Application Laid-Open Documents No. H02-204133, No. H05-42838, No. H06-17889, No. H06-34...
