Appl. No.:

10/991548

Inventors:

Alexander Serkh - Troy MI, US
Imtiaz Ali - Lathrup Village MI, US

Assignee:

The Gates Corporation - Denver CO

International Classification:

F01B 21/04

US Classification:

60698

Abstract:

An auxiliary power system for a motor vehicle primary engine used to drive primary engine accessories when the primary engine is not operating. The system comprises a secondary engine that drives a hydraulic pump. The hydraulic pump is connected to a hydraulic motor. The hydraulic motor is integrated with an accessory belt drive system on a primary engine. The secondary engine drives the ABDS system through the hydraulic pump and hydraulic motor when the primary engine is not operating, thus allowing various primary engine accessories such as air conditioning to be operated while the primary engine is off. A one-way clutch on the primary engine crankshaft prevents the primary engine crankshaft from being turned when the hydraulic motor is driving the belt. A one-way clutch on the hydraulic motor prevents it from being driven when the primary engine is in operation.

International Classification:

G01L 1/22

US Classification:

73862045

Abstract:

A transducer for detecting a shaft dynamic behavior. The transducer comprises an arcuate sensor member supported between an inner member and an outer member. At least one strain gage is attached to a surface of the arcuate sensor member to detect a surface strain caused by a shaft dynamic behavior. The inner member, outer member and arcuate sensor member are substantially coplanar. The inner member comprises a means for attaching the transducer to a mounting surface. The inner member may also comprise a self-aligning feature to optimize a sensor sensitivity.

International Classification:

G01L 3/00

US Classification:

7386208

Abstract:

A method and apparatus for measuring an operating front end accessory belt tension using a hubload transducer and a torque transducer. The hubload transducer comprises concentric rings with a strainable member disposed in a coplanar fashion between an inner and outer ring. The hubload transducer is used with a non-torque transmitting idler pulley. The torque transducer comprises a strainable cylindrical member connected to a belt bearing surface and a rotating shaft. The torque transducer will transmit a torque to a driven accessory. It is used on accessories such as an air conditioner compressor or power steering pump. Signals from the hubload transducer and torque transducer as used to calculate a drive efficiency as well as belt span tensions between the driver and driven accessories.

Assignee:

The Gates Corporation - Denver CO

International Classification:

F02B 77/00

US Classification:

123198R, 123195 A

Abstract:

The invention is an improved internal combustion engine having a crankshaft, an accessory, a motor/generator, and a belt-drive system. The belt drive systems includes a crankshaft pulley, an accessory pulley, a motor/generator pulley, a belt tensioner, a belt tensioner pulley, and a power transmission belt trained about the crankshaft pulley, the accessory pulley, the motor/generator pulley, and the belt tensioner pulley. The belt tensioner pulley contacts the belt at a start-slack-side span. It is improved by the tensioner being asymmetrically biased in a direction tending to cause the power transmission belt to be under tension.

International Classification:

F16H 37/02
F16H 13/08

US Classification:

475210, 475196

Abstract:

An infinitely variable speed ratio planetary ball transmission comprising planetary members in rolling contact with moveable inner and outer races and a constant speed accessory drive system utilizing the transmission. The transmission is infinitely variable between ratios of approximately 0. 3 and 1. A transmission input shaft is connected to a prime mover such as a vehicle engine crankshaft by a drive belt. The transmission comprises at least one output shaft that is coaxial with the input shaft. An output pulley is attached to the output shaft. A belt is engaged between the output pulley and various engine accessories. A second end of the transmission output shaft may be directly coupled to an engine accessory mounted on the transmission. An included control system senses a crankshaft speed. A processor analyses the crankshaft speed and accordingly adjusts the transmission ratio using a stepper motor connected to a worm drive to maintain a constant output speed regardless of crankshaft speed.
