Abstract: A vehicle transmission has at least three transmission gears. The at least three transmission gears are selectively engaged by at least three shifting sleeves. The shifting sleeves are actuated by two shift forks. Each shift fork is moved by a corresponding shift drum. The shift drums are disposed on a shift drum shaft. By rotating the shift drum shaft, each of the at least three transmission gears can be engaged in sequence. The two shift drums are spring biased.

Abstract: The present invention provides a shift-drum apparatus for a gear-type transmission including a plurality of shift forks and a shift drum provided at its outer peripheral surface with a plurality of shift grooves, in which a state of the gear-type transmission is shifted between a neutral state and a plurality of transmission gear stages. The number of the shift forks is the same as the number of the transmission gear stages, and each of the shift grooves includes one or more gear-shifting recesses that are depressed in an axial direction of the shift drum. The shift forks are biased in the axial direction respectively by springs toward the corresponding gear-shifting recesses. Two of the gear shifting recesses are formed in at least one of the shift grooves, while two of the shift forks are engaged with the shift groove.

Abstract: An object of the invention is to change a layout structure of a hydraulic continuously variable transmission apparatus (HST) particularly constituting a hydromechanical continuously variable transmission apparatus (HMT) as a continuously variable transmission apparatus, thereby achieving a simplification of structures of a working vehicle and a traveling drive system, and an easiness of a maintenance. In a working vehicle provided with an HMT structured such as to combine an HST and a planetary gear mechanism as the traveling drive system so as to output and rotate a power of an engine while shifting gear, the HST is provided with a hydraulic pump and a hydraulic motor integrally in a front wall of a transmission case, and is arranged in an upper side of a transmission shaft transmitting the power to the transmission case from the engine.

Abstract: A vehicle has an engine, an accelerator for controlling the rotary speed of the engine, an axle and a multi-speed transmission for transmitting power from the engine to the axle. The multi-speed transmission includes an odd-numbered speed drive train for an odd-numbered speed level, a first clutch for the odd-numbered speed drive train, an even-numbered speed drive train for an even-numbered speed level, and a second clutch for the even-numbered speed drive train. In correspondence to operation of the accelerator and an actual speed of the axle, either the odd-numbered speed drive train or the even-numbered speed drive train is selected so as to transmit power from the engine to the axle. A shift-up or shift-down timing between the odd-numbered speed level and the even-numbered speed level relative to variation of the actual speed of the axle is changed according to detection of a tilt angle of the vehicle or a weight of the vehicle.

Abstract: A transmission for a working vehicle for transmitting drive power from an engine to a driving axle that includes: a flywheel including a flywheel body operatively connected with the engine and a flywheel housing for accommodating the flywheel body; a main-speed-change unit including a main-input shaft operatively connected with the engine via the flywheel body and a main-output shaft for outputting drive power to be transmitted to the driving axle; and a sub-speed-change unit including a sub-input shaft and a sub-output shaft, and disposed at a distance from the main-speed-change unit. The engine, the flywheel and the main-speed-change unit are integrally connected with each other so as to vibrate freely relative to a vehicle frame, and the main-output shaft of the main-speed-change unit is operatively coupled with the sub-input shaft of the sub-speed-change unit via a vibration-absorbing shaft coupling.

Abstract: The present invention provides a hybrid vehicle including a first transmission path that transmits a traction of an engine to driving wheels and a second transmission path that transmits a traction of a motor to the driving wheels, and the hybrid vehicle runs by alternatively selecting either the first or second transmission path or in combination thereof. The first transmission path has a first reduction gear ratio that is defined to be smaller than a reduction gear ratio at which a maximum vehicle speed can be achieved by the traction of the engine alone.

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).

Abstract: A propelling transmission system of a tractor comprising a front transmission for driving front wheels and a rear transmission for driving rear wheels. The front transmission receives drive from an engine mounted at a front position of the tractor, through a main clutch housed in a clutch case, and transmits the drive to the rear transmission. The rear transmission returns part of the drive to a front wheel change speed mechanism included in the front transmission. The front transmission is housed in a front transmission case directly connected to a lower rearward position of the clutch case.
