Abstract
In a vehicle transmission assembly which includes a hydrostatic transmission (14) and mechanical transmission mechanism (21) for driving rear wheel axles (20) of the vehicle at a variable speed, a hydraulic pump (16) and hydraulic motor (17) of the hydrostatic transmission are mounted on a plate member (30), secured to a front of a transmission casing (15), at an upper and lower locations such that only the motor is disposed within the transmission casing at a location above the mechanical transmission mechanism. The mechanical transmission mechanism includes plural transmission shafts (31, 32, 33) all extending laterally of the transmission casing and is connected drivenly to the motor. Pump shaft (18) of the hydraulic pump is adapted to drive at least one of a rear-PTO shaft (23) and mid-PTO shaft (24) through a drive shaft (41) disposed co-axially with the pump shaft, a fluid-operated PTO-clutch (42) mounted on the drive shaft, and a gear train (43; 143; 243) disposed at a rear end portion within the transmission casing. A compactness of the transmission assembly and turnability of the vehicle with a small radius of turn are assured.
