A four-wheel drive hybrid vehicle comprises: an engine 1 disposed on a side of front wheels 4; a first motor 7; an exhaust pipe 17 for discharging exhaust gas from a rear side of the vehicle; a first propeller shaft 12 that delivers output power of the engine 1 to rear wheels 3; a transfer 11 that distributes the output power of the engine 1 to the front wheels 4; a second propeller shaft 13 that delivers a drive force from the transfer 11 to the front wheels 4; and a second motor 20 that applies torque to the front wheels 4. The second propeller shaft 13 is arranged on the other side of the exhaust pipe 17 across the first propeller shaft 12 while being connected to the second propeller shaft 13.

In a transfer (22), a high thrust can be given to a front-wheel driving clutch (50) by a high magnification function of a screw mechanism (86). Further, a necessary stroke for an operation of a high-low switching mechanism (48) can be obtained by the screw mechanism (86). Accordingly, with the use of one motor (84), the screw mechanism (86), and a transmission mechanism (88), it is possible to perform a switching operation of the high-low switching mechanism (48) and a torque adjustment of the front-wheel driving clutch (50) by the same system. Hereby, it is possible to perform, with accuracy, the switching operation of the high-low switching mechanism (48) and the torque adjustment of the front-wheel driving clutch (50), based on a motor rotation angle Am of one motor (84).

A constant mesh gear transmission has an input shaft (21, 22), two layshafts (31, 35) and an output shaft (23). Gear wheels are selectively connectable to shafts to provide forward and reverse speed ratios. A common central web (39) provides central support bearings for the shafts. The transmission is stiffened, and allows assembly of components from either end to the middle.

摘要:
The invention relates to a drive device for a change-speed transmission for motor vehicles, having at least one transmission input shaft (14), at least one axially parallel output shaft (18), having a plurality of gearwheel sets which are arranged on the shafts (14, 18) with fixed gearwheels and idler gears which can be switched via synchronizer clutches in order to form forward gears, and having at least one separating clutch (K1, K2). According to the invention, a planetary gear mechanism (40) which can be switched over into two transmission stages is connected upstream of the gearwheel sets of the forward gears (1 to 9), which planetary gear mechanism (40) has a driven input element (42), an output element (50) which outputs to the input shaft (14), and a transmission element (46) which can be braked or coupled in order to switch over the transmission stages, wherein the transmission element (46) can be coupled to an electric machine (54), by means of which the transmission element (46) can be fixed or can be driven in both rotational directions.
