Abstract: A power take-off (PTO) unit takes-off power from a transmission for driving a first drive wheel of a vehicle and transmits the taken-off power to a second drive wheel of the vehicle. The PTO unit includes a PTO casing, a PTO shaft and a brake for braking the PTO shaft. The PTO casing is mounted on another casing incorporating the transmission. The PTO shaft is journaled by the PTO casing, drivingly connected to the transmission shaft of the transmission and drivingly connected to the second drive wheel. The brake is disposed in the PTO casing. The brake includes an unslidable pawl that is not slidable axially in the axial direction of the PTO shaft, and includes a slidable pawl that is slidable axially in the axial direction of the PTO shaft so as to selectively engage or disengage with and from the unslidable pawl.

Abstract: A method to prevent overspeed of an internal combustion and attached ancillary devices in a mechanized vehicle includes one or more procedures to prevent improper gear selection to disengage the lockup function of a torque converter, to initiate engine braking and to destroke variable displacement hydraulic pumps. Requested gear selection in downshift is allowed only after interrogation of brake pressure, ground speed, shift selection requested and torque converter output speed. The torque converter lock-up solenoid is activated or deactivated in response to torque converter output speed which is compared to selected values to engage or disengage. Engine braking using a compression release braking system response to engine RPM in manual or automatic mode to prevent overspeed. Variable displacement pumps are destroked in response to engine RPM by adjusting swashplate control. The systems may be operated independently or under the control of a common electronic module.

Abstract: A vehicular transmission comprises an engine E, a continuously variable transmission CVT and a starting clutch 5. The driving force from the engine E is conveyed through the continuously variable transmission CVT with a speed change to a countershaft 2, and the starting clutch 5 is used to convey this driving force from the countershaft 2 to wheels of a vehicle. In this power transmission, when the vehicle is decelerated for a halt, the fuel supply to the engine is terminated to decelerate the vehicle. In addition, the starting clutch 5 is released gradually under a predetermined condition, and then the engine E is stopped to bring the vehicle into a halt.
