ABSTRACT:
An HMT apparatus (T) is mounted on a vehicle (A). In the HMT apparatus (T), input rotational force from an engine (13) is once divided into two systems which are then transmitted by an MT device (23) and by an HST device (24) respectively and are re-synthesized for transfer toward wheels (12) and (16). The HMT apparatus (T) is disposed on the vehicle-body right side of the engine (13) which is sideways-mounted on a vehicle body (1), and its input and output shafts (25) and (26) are disposed in parallel with a crank shaft (13a) of the engine (13) and are disposed to run parallel with each other. The input shaft (25) is coupled directly to the crank shaft (13a) and an input gear (27) of the MT device (23) is mounted on the input shaft (25), and a hydraulic piston pump (30) of the HST device (24) is connected to the right side end of the input shaft (25). A planetary gear mechanism (28) of the MT device (23) is connected to the right side end of the output shaft (26), and a hydraulic piston motor (31) of the HST device (24) is connected to the right side of the planetary gear mechanism (28). By virtue of such arrangement, it is possible to improve the degree of freedom of the layout of each component of the HMT apparatus (T), to reduce axial dimensions, and further to provide improvement in the cooling property and maintenance property of the section of the HST device (24).
