  • Patent number: 9032822
    Abstract: The arrangement of driven gears on a countershaft in a main speed change mechanism is shortened in an axial direction, whereby the main speed change mechanism can be made compact in the axial direction. Driven gears on a countershaft of a main speed change mechanism are successively arranged from front to rear in descending order of speed. A sub-low-speed drive gear for a sub-speed change mechanism is provided in front of the highest-speed driven gear on the countershaft, and the next-highest-speed driven gear serves as a sub-high-speed drive gear for the sub-speed change mechanism. A sub-low-speed driven gear and a sub-high-speed driven gear for the sub-speed change mechanism are provided on an output shaft to be engaged with the sub-low-speed drive gear and the next-highest-speed driven gear, respectively, and the highest-speed driven gear, the sub-low-speed drive gear, and the next-highest-speed driven gear are caused to overlap in a fore-and-aft direction.

    Abstract: A vehicle PTO driveline (10) in which a PTO input shaft (11) drives a PTO wet clutch (12) which when engaged drives a PTO output shaft (13). The driveline has an eccentric formation (34) on the input shaft (11) which oscillates a pumping piston (31) when the input shaft rotates, which piston pumps cooling/lubricating fluid from a reservoir (25c) to the wet clutch (12). The piston is connected with the eccentric formation by a ring (33) which surrounds the eccentric formation (34) and a hollow tube (32) which is attached to the ring and which carries the piston at a lower end, the piston oscillating inside a chamber (31a) when the input shaft rotates. The chamber (31a) is connected with the fluid reservoir (25c) and the oscillating piston pumps the fluid along the hollow tube (32) into the ring (33) which then delivers the fluid into internal passages (38) in the input shaft from where the fluid flows to the wet clutch.

The rotor shaft is coaxial with the tubular shaft and a splined coupling portion formed between the rotor shaft and the tubular shaft. By virtue of the invention, mechanical loads of the auxiliary are transmitted to a lesser extent to the rotor shaft support bearings and to the auxiliaries support gear train.

    Abstract: A power take-off (PTO) includes new features to make it more environmentally friendly, improve service life, and reduce service part inventory. The idler shaft, which holds the pick-up gear for connecting the PTO to a transmission, may include a splined shaft. The pick-up gear and an idler gear may be mounted on the splined in different configurations. The output of the PTO, including a splined output and an output plate for connecting to secondary equipment such as a hydraulic pump, can be easily replaced or reconfigured to work with different configurations of secondary equipment.

  • Publication number: 20110077113
    Abstract: A pass-through power take-off (PTO) mechanism for use with renewable energy systems is described to extract power from a linearly moving tether under high tension and to convert it to rotary power such as for driving an electric generator. Three such embodiments are described. The first uses two adjacent timing belts and transfers power from tether to PTO via friction. The second embodiment uses two adjacent roller chain loops and a mechanical engagement method to transfer power from tether to PTO. The third embodiment uses two adjacent double-sided timing belts and either a synchronous or an asynchronous method to transfer power from the tether to the PTO.

  • Publication number: 20100282007
    Abstract: A motor vehicle including an internal combustion engine, which utilizes a power take-off mechanism, that converts the reciprocating linear motion of the piston into reciprocating angular motion of the gearing cylinder, being in gear with the partially teethed connecting rod via right angled teeth and rotating motion of the drive shaft which runs coaxially through the gearing cylinder and vice versa. The mechanism has means for causing the piston to pause while the drive shaft rotates. The motor vehicle comprises a fuel heater, an exhaust cleaner including a sinuous tube and liquid for separating impure components of exhaust, a main control module controlling the function of the engine and piston function, a second control module controlling the engine during the minimal running state, thus controlling the pause time of the piston, a third control module controlling the energy flow to the heater, the fuel feeder, and the air feeder.

  • Patent number: 7684918
    Abstract: The invention relates to a PTO brake control system. There is a need for an improved and safe PTO brake control system. A PTO may be put into a driven and a non-driven condition an is braked by a PTO brake. A PTO brake control system includes a vehicle speed sensor and an ECU for controlling the PTO brake. The ECU deactivates the PTO brake when the vehicle is stationary and the PTO is not driven. This allows the PTO to be manually rotated to facilitate coupling of the PTO to an implement.

  • Publication number: 20090223312
    Abstract: The present invention can easily determine a specification which includes a PTO clutch mechanism or a specification which includes no PTO clutch mechanism. According to the present invention, in a tractor which detachably mounts a PTO portion on a transmission portion, a PTO clutch mechanism is arranged in the inside of the PTO portion. Accordingly, it is possible to easily determine the specification which includes the PTO clutch mechanism or the specification which includes no PTO clutch mechanism depending on whether the PTO clutch mechanism is preliminarily assembled in the PTO portion or not in a stage that the PTO portion is assembled and, at the same time, it is possible to easily complete the assembling by merely mounting the PTO portion on the transmission portion. Further, by taking steps opposite to the above-mentioned steps, it is possible to easily perform the maintenance of the PTO clutch mechanism or the like.
