Abstract: A power take off unit includes an input gear, an output gear, and an intermediary gear that cooperate to transfer power from a rotational power source to an operating target. The power take off unit has a control module that biases the intermediary gear relative to the input gear and the output gear to reduce gear rattle vibrations associated with intermeshed tooth looseness.

Abstract: A hybrid powertrain includes an output shaft, a combustion power section for providing a first torque, an electric power section for providing a second torque, and an output transmission for transmitting the first torque between the combustion power section and the output shaft and transmitting the second torque between the electric power section and the output shaft. The combustion power section includes an internal combustion engine with a combustion shaft for outputting the first torque, a generator with a generator shaft for converting the first torque into electric energy, and a variable belt transmission for variably translating the first torque. The belt transmission includes a combustion-side cone pulley pair with a first axially movable pulley arranged on a generator shaft side, an output-side cone pulley pair with a second axially movable pulley, and a belt for variably torque-transmittingly connecting the combustion-side cone pulley pair to the output-side cone pulley pair.

Abstract: A gear includes a gear body to be attached to a distal end of a driving shaft in an axial direction of the driving shaft and including teeth each extending obliquely with respect to the axial direction, and a stopping portion included in the gear body and configured in such a manner as to allow the driving shaft to which the gear body is attached to move in a circumferential direction. When the driving shaft moves in the circumferential direction, the stopping portion is enabled to stop the gear body from moving in the axial direction, the stopping portion stopping the gear body by coming into contact with a portion of the driving shaft.

Abstract: A planet carrier assembly includes a rotational axis, a carrier and a carrier flange. The carrier has circumferentially spaced first driver elements formed thereon and the carrier flange has circumferentially spaced second driver elements formed thereon. The second driver elements are interconnected with the first driver elements at common contact areas in an interlocking manner. The carrier flange is axially secured to the carrier in an axial direction by plastically deformed material at the common contact areas. In an example embodiment, the plastically deformed material is displaced from the first driver elements or the second driver elements.

Abstract: The present invention is a steering system for a beam-type solid axle arrangement. The steering system is designed to operate in conjunction with the triangulated link-style suspension system with zero bumpsteer during suspension travel and negligible bumpsteer during articulation. Accurate steering throughout suspension operations is satisfied with mechanical linkages that include a slow ratio rack and pinion gearset and unique augmented chain and sprocket assembly. The slow ratio of the rack and pinion gearset ensures negligible bumpsteer during articulation, thereby leading to negligible if any bumpsteer throughout operation of the suspension system. Meanwhile, augmentation of the chain and sprocket assembly defines a steering quickener effect thereby speeding up the rack and pinion gearset and restoring quick steering response. Effortless steering is ensured by appropriate use of electric or hydraulic assist devices.

Abstract: An orbital tensile drive is herein disclosed, along with systems and methods associated therewith. The orbital tensile drive uses a tensile element that is conveyed around a static, fixed shaft and a rotating output shaft. This is facilitated via multiple orbiting idler pulleys that are mounted to an orbiter body. The static and rotating shafts, as well as the orbiting assembly, share a common axis. Input rotation to the orbiter body is transformed into lower-speed, higher-torque rotation at the rotating output shaft. The present invention has many potential applications including, but not limited to, robotics.
