Embodiment Construction

[0035] The present application relates to a variable vane hydraulic device that utilizes a ring and an adjuster that rotates the ring relative to each other to vary the hydraulic displacement of the device. Such hydraulic means may include, for example, a variable vane pump / motor arrangement. According to a further example, the hydraulic device may include a variable vane device operable as a vane pump / motor and a hydraulic coupling. The present application also discloses vehicle systems that may utilize variable vane hydraulics and other accessories to operate in various operating modes.

[0036] figure 1 A perspective view of a portion of hydraulic device 10 including regulator 12, rings 14A and 14B, and supports 16A and 16B is shown. The first ring 14A includes an outer surface 18A, an inner surface 20A, and a channel 22A. The second ring 14B includes an outer surface 18B, an inner surface 20B and a channel (not shown). The adjuster 12 includes an inner surface 24 , an ...

Abstract

A hydraulic device can include two or more rings, a rotor having a plurality of vanes, and an adjuster. The two or more rings can be rotatably mounted within the hydraulic device and arranged adjacentone another configured for relative rotation with respect to one another. The rotor can be disposed for rotation about an axis within the two or more rings and can have a plurality of circumferentially spaced slots, each slot having at least one of the plurality of vanes located therein. The plurality of vanes can be configured to be movable between a retracted position and an extended position where the plurality of vanes work a hydraulic fluid introduced adjacent to the rotor. The adjuster can be configured to translate linearly to rotatably position the two or more rings relative to one another to increase or decrease a displacement of the hydraulic fluid between the rotor and the two or more rings.
