| 20120193188 | ENGINE START STOP APPLICATIONS FOR SOLENOID PUMPS - A solenoid pump and associated hydraulic circuitry are intended for use in automatic transmissions capable of engine start stop (ESS) operation. In a first embodiment, a solenoid pump provides pressurized hydraulic fluid to respective inputs of two way check valves. The other inputs are provided with controlled hydraulic fluid from a transmission valve body. The outputs of the check valves are provided to those hydraulically operated torque transmitting devices associated with first gear. The solenoid pump is activated when the transmission is in gear and the engine is stopped to maintain hydraulic pressure in those actuators associated with first gear in order that a first gear vehicle launch may be quickly and smoothly achieved when the engine is restarted. A second, similar embodiment provides hydraulic fluid to actuators associated with reverse gear. A third embodiment includes a solenoid pump and a latching solenoid valve both communicating with a hydraulic supply between a variable output solenoid valve and a hydraulic actuator in an automatic transmission which maintains clutch pressure by compensating for leaks in the hydraulic components. In a fourth embodiment, a solenoid pump provides pressurized hydraulic fluid to the exhaust backfill circuits of one or more hydraulic operators in an automatic transmission. | 08-02-2012 |

| 20110315506 | OIL PUMP MOUNTING STRUCTURE - A mounting structure for mounting a separate shaft type oil pump in a case of a transmission. The separate shaft type oil pump is driven by a shaft that is separate from and rotated in cooperation with a shaft arranged in a torque input route extending from an engine to the transmission to supply hydraulic oil to a transmission oil pressure control mechanism. The mounting structure includes a spacer coupler that fastens the oil pump to the transmission case. The spacer coupler includes a plurality of spacers that couple the oil pump and the transmission case. An oil passage is formed in the spacers of the spacer coupler to connect an oil pressure system, which includes the oil pressure control mechanism, and the oil pump. A manual shaft for operating the transmission is arranged in a clearance between the spacers of the spacer coupler. | 12-29-2011 |
| 20140060995 | HYBRID CLUTCH ASSEMBLY FOR AN AIRCRAFT - A hybrid clutch assembly inserted between an internal combustion engine and the propeller of an aircraft to provide a hybrid-powered aircraft. The hybrid clutch assembly allows a direct current (DC) electric motor to be attached to the hybrid clutch assembly using drive belts. The hybrid clutch assembly allows the internal combustion engine to transmit power to the aircraft's propeller and freely spin the DC motor. The DC motor can transmit power to the aircraft's propeller without turning the internal combustion engine. The hybrid clutch assembly independently allows either the internal combustion engine or the DC motor in parallel to power the aircraft's propeller. The hybrid clutch assembly includes a hybrid clutch, a drive belt housing, a hybrid clutch assembly shaft, and an adapter plate. The hybrid clutch connects to the drive belt housing a hybrid clutch assembly shaft. The adapter plate enables connection of the hybrid clutch to the internal combustion engine propeller flange. The drive belt housing enables connection of the hybrid clutch to the propeller. The DC motor is connected to the drive belt housing drive belts. | 03-06-2014 |

| 20080264752 | Free coaster bicycle hub - A free coaster bicycle wheel driving apparatus having a clutch that employs radially acting components. A drive sleeve has an inner cylindrical wall surface mounted coaxially about a wheel mounting shaft and an outer cylindrical wall surface that is eccentric relative to the drive sleeve inner wall surface. The outer surface of the drive sleeve cooperates with a power transmission sleeve that has an inner cylindrical wall surface that is eccentric relative to its cylindrical outer wall surface. The power transmission sleeve is interposed between the drive sleeve and a wheel hub. When the eccentric lobe on the drive sleeve is in opposition to the eccentric lobe on the surrounding power transmission sleeve, the sprocket is disengaged from the wheel hub. Forward rotation of the sprocket jams the lobe of the drive sleeve against the power transmission sleeve, forcing its cam lobe outwardly into frictional engagement with the wheel hub. | 10-30-2008 |

| 20100320053 | Driving device for an adjusting system of a motor vehicle - A driving device for an adjusting system of a motor vehicle includes a transmission with a drive element rotatably mounted about an axis of rotation for introducing a torque, a driven element rotatably mounted about the axis of rotation for delivering a torque, and a wrap spring brake device for transmitting a drive-side torque introduced by the drive element to the driven element and for blocking a driven-side torque applied on the driven element. It is provided that the drive element and the driven element each are mounted on a stationary portion of the transmission. In this way a driving device is created, whose drive element and driven element can have low bearing tolerances and which in addition is optimized in terms of friction to provide a smooth operation. | 12-23-2010 |
| 20110094848 | METHOD AND APPARATUS FOR DETERMINING THE APPARENT OPERATIONAL INTEGRITY OF A NO-BACK DEVICE - This invention provides an improvement in a no-back device having a ball screw connected to a variable load of reversible polarity (±L) and having a portion penetrating a housing. The device includes a braking mechanism acting between the housing and the ball screw for producing a force that resists movement of the ball screw in the direction of an “aiding” load, but does not substantially resist movement of the ball screw in the direction of an “opposing” load. The improvement broadly includes: a first spring acting between the housing and the braking mechanism for exerting a first preload force (F1) on the braking mechanism for simulating the application of an external load on the ball screw in one of the directions; whereby the apparent operational integrity of the no-back device may be checked when no external load is applied to the ball screw. In use, the apparatus performs the steps of: providing a first spring; causing the first spring to exert a first preload force (F1) on the braking mechanism; determining the actual torque (Ta) required to move the ball screw while the aircraft is on the ground; comparing the actual torque with a theoretical torque (Tt) required to move the ball screw; and inferring that the no-back device is not operating correctly if the actual torque is less than the theoretical torque; thereby to test the apparent operational integrity of the no-back device when the aircraft is on the ground. | 04-28-2011 |
| 20140197004 | Gearbox Lock Mechanism - The gearbox lock mechanism for a post bole auger has a collar coupled to a lower end of a right angle gearbox, the collar rotatable upon operation of the gearbox. The collar comprises a semi-circular outer edge and a fiat side. A male-threaded nipple extends from the collar and threads onto the auger shaft. A lock bar is coupled to the gearbox and acts as a positive lock to lock the collar in place for removal of the shaft from the gearbox. The lock bar is rotatable from a locked position whereby the lock bar is aligned with and contactable with the flat side of the outer edge of the collar, to an unlocked position whereby the lock bar does not contact the flat side of the outer edge of the collar. | 07-17-2014 |
