Title:
HYDROMECHANICAL SPEED-CHANGE DEVICE AND VEHICLE HAVING SPEED CHANGE DEVICE MOUNTED THEREON
Document Type and Number:
WIPO Patent Application WO/2002/064999
Kind Code:
A1
Abstract:
A vehicle (A) has an HMT (T) mounted thereon that once divides an input rotating force from an engine (13) into two systems and transmits them respectively to an MT (23) and an HST (24), and then recombines them and delivers the same to wheels (12, 16). The HMT (T) is disposed on the vehicle body right-hand side of an engine (13) transversely mounted on the vehicle body (1), and an input shaft (25) and an output shaft (26) are disposed parallel with the crank shaft (13a) of the engine (13) and side by side with each other. The input shaft (25) is connected directly to the crank shaft (13a), and the input gear (27) of the MT (23) is disposed on the shaft, while the hydraulic piston pump (30) of the HST (24) is connected to the vehicle body right-hand side end of the input shaft (25). The planetary gear mechanism (28) of the MT (23) is connected to the vehicle body right-hand side end of the output shaft (26), and connected to the vehicle body right-hand side thereof is the hydraulic piston motor (31) of the HST (24). This arrangement improves the degree of freedom of layout of the components in the HMT (T), reduces the axial dimension, and improves the coolability and maintainability of the HST (24) portion.
