摘要： The present invention provides a load controller for use in a hydrostatic transmission for a work vehicle that is free from control failure caused by deterioration of the constituent components, and that can be miniaturized and simplified in structure compared to conventional load controllers. In the work vehicle, power supplied from an engine (E) is branched to drive an implement system and a traveling system. A hydrostatic transmission (1) is provided in the traveling system. The hydrostatic transmission (1) connects, in an oil-hydraulic closed circuit, an oil-hydraulic pump (2) driven by the engine (E) and an oil-hydraulic motor (4) driven by the oil-hydraulic pump (2). The load controller is provided with a bypass oil line for bypassing an oil line that has high pressure during forward movement (3a) in the oil-hydraulic closed circuit to reach an oil line that has low pressure during forward movement (3b) or an oil tank (T); a first opening/closing valve for opening or closing the bypass oil line (8); and an opening/closing valve (9) controller that detects a load applied to the engine (E) while traveling during working and opens the first opening/closing valve (9) when the load exceeds a predetermined level.

摘要： A reversing gear assembly (13) for a marine angle drive comprises a horizontal input shaft (15), to be connected to a horizontally mounted engine (11) and an inclined output shaft (16) to be connected to the propeller shaft (12). Gear casing (14) includes an intermediate shaft (17) which extends parallel with the output shaft (16). The input shaft (16) fixedly mounts a cylindrical gear (22) which meshes with a forward drive conical gear (23) on the output shaft (16) and with a reverse drive cylindrical gear (25) on the intermediate shaft (17). Center of engagement between the cylindrical gears (22, 25) is located on the sole common perpendicular line of the input and intermediate shafts (15, 17). Reverse drive gear train further includes two meshing cylindrical gears (26, 24) on the intermediate and output shafts (17, 16). The gears (23, 24) on the output shaft (16) are selectively coupled to this shaft by clutch means (32).The parallel arrangement of the output and intermediate shafts (16, 17) and the use of a single conical gear (23) contributes to reducing the manufacturing cost while permitting drive of propeller shaft in either direction with equal power.

The flywheel housing has a first end connected to the engine and a second open end opposite to the first end along the longitudinal axis of the vehicle. The intermediate housing has a hollow shape with a first end and a second end located along the longitudinal axis of the vehicle. The first end has an abutting surface against which the second end of the flywheel housing abuts, a support surface located radially inwardly of the abutting surface so as to support the HST unit, and an opening surrounded by the support surface. The opening serves as a first-end opening of the intermediate housing along the longitudinal axis of the vehicle. The abutting surface and the support surface along the longitudinal axis of the vehicle are located so that at least a portion of the HST unit is accommodated within the flywheel housing.
