| 20080214342 | Two-Armed Tensioner for the Drive Belt of a Motor Vehicle - Described herein is a tensioner for a belt of a drive of a motor vehicle, comprising: at least two idle pulleys designed to co-operate with respective belt runs of the belt; two arms bearing the pulleys; and elastic means acting at least indirectly on the arms for tensioning the belt, in which the arms are constrained to one another, and at least one of the arms is hinged to a first mobile axis. | 09-04-2008 |
| 20090069134 | Dual idler structure for an elliptical trainer - A dual idler structure of an elliptical trainer can tighten a transmission belt, without easily causing the belt to be slipped upon rotating clockwise or counterclockwise. By operating an upper and a lower stopping bolt to abut an upper and a lower idler set, resilience to the idler sets by the transmission belt upon rotating clockwise or counterclockwise is prevented, such that the belt is prohibited from being easily slipped. | 03-12-2009 |
| 20090318253 | BELT OVERLOAD DEVICE - An apparatus including a belt support system having a first belt support roller and a system for automatically moving the first belt support roller. The belt support system partially wraps a continuous belt on a belt drive roller. The belt support system includes the first belt support roller at an upstream side of the belt drive roller and a second belt support roller at a downstream side. The system for moving the first belt support roller moves the first roller from a first location relative to the belt drive roller to a second different location, based upon a predetermined load of the belt on the first belt support roller to thereby reduce an amount of wrap of the belt on the belt drive roller and reduce a length of the belt located proximate to the belt drive roller between the first and second belt support rollers. | 12-24-2009 |
| 20110256971 | Chain Tensioner - A roller-chain tensioning assembly includes a resilient bow-shaped structure to which are mounted first, second and third guide wheels. These guide wheels are mounted in such manner that a roller chain can be threaded around said first guide wheel on side facing away from said bow, around said second guide wheel on side facing said bow, and around said third guide wheel on side facing away from said bow. | 10-20-2011 |
| 20110281676 | Starter Alternator Assembly Comprising a Poli-V Belt and Poli-V Belt - Starter-alternator assembly including a poly-V belt comprising a body made of elastomeric material, a plurality of filiform resistant inserts longitudinally embedded in the body, and a coupling portion integrally connected to the body and comprising a plurality of V-shaped ribs set alongside one another and alternating with V-shaped grooves. The belt has a dynamic modulus, with a tensile force pre-set at 600 N at a frequency 15 Hz, that after 10 000 cycles is higher than 110 000 N/rib/branch, and is advantageously made with resistant inserts obtained from at least one first fibre material and one second fibre material. | 11-17-2011 |
| 20130040770 | TENSIONING DEVICE FOR A BELT DRIVE AND ELECTRIC MACHINE WITH SUCH A TENSIONING DEVICE - A tensioning device ( | 02-14-2013 |
| 20130203535 | TENSIONING DEVICE FOR A TRACTION MECHANISM DRIVE OF AN INTERNAL COMBUSTION ENGINE - A tensioning device ( | 08-08-2013 |
| 20130260932 | TENSIONER AND ENDLESS DRIVE ARRANGEMENT - A Y-tensioner is provided for tensioning the endless drive of an engine having a starter-generator unit (SGU). First and second arms of the Y-tensioner are pivotable about a common first axis. The second arm is articulated to the first arm and spring-loaded to pivot about a second axis spaced from the first axis. The first arm tensions a first strand of the endless drive which becomes the tight side when the SGU operates as a starter and the second arm tensions the second strand which becomes the tight side when the SGU operates as a generator. Pivoting of the Y-tensioner about the first axis enables the first or second arm to better align with the dominant force on the pulleys as the SGU shifts between starter and generator modes, reducing torque about the second axis to reduce the size of the spring that tensions the two arms together. | 10-03-2013 |
| 20140045631 | System and Method for Testing Crash Avoidance Technologies - A cam actuated hydraulic brake system and an in plane tensioner pulley belt drive system may be used on autonomous vehicles, such as dynamic motion elements for the evaluation of various crash avoidance technologies. The brake system utilizes a cam driven by a servo to push the piston push rod of a hydraulic master brake cylinder, thus distributing pressurized brake fluid throughout the brake system. The pulley drive system uses an articulating arm for the driven pulley, and that arm may also have connected to it one or two tension pulleys, each of which is in contact with the belt. Because the drive pulley and the tensioner pulleys pivot about the same pivot axis, the needed belt length remains nearly constant across the entire range of the articulating arm. | 02-13-2014 |
| 20140378254 | CHAIN TENSIONER AND CHAIN TRANSMISSION DEVICE - A chain guide is provided which reduces moving resistance of a camshaft-driving, torque-transmitting timing chain. The chain guide includes a guide base ( | 12-25-2014 |
| 20150345597 | ORBITAL TENSIONER ASSEMBLY - In an aspect, a tensioner is provided for tensioning an endless drive member that is engaged with a rotary drive member on a shaft of a motive device. The tensioner includes a base that is mountable to the motive device, a ring that is rotatably supported by the base in surrounding relationship with the shaft of the motive device and which is rotatable about a ring axis, a tensioner arm pivotally mounted to the ring for pivotal movement about an arm pivot axis, and first and second tensioner pulleys. The first tensioner pulley is rotatably mounted to the tensioner arm. The tensioner arm is biased towards a first span of the endless drive member on one side of the rotary drive member. The second tensioner pulley is rotatably mounted at least indirectly to the ring and is biased towards a second span of the endless drive member on another side of the rotary drive member. The ring is rotatable in response to hub loads in the first and second tensioner pulleys that result from engagement with the first and second spans of the endless drive member. | 12-03-2015 |
| 20150369347 | STARTER GENERATOR BELT TENSIONER - A generator arrangement for an auxiliary-assembly belt drive of an internal combustion engine, having a starter generator (1) with a belt pulley (6) and a belt tensioner (2) which includes the following:—a first tensioning lever (8) with a first tensioning roller (4),—a second tensioning lever (9) with a second tensioning roller, these tensioning rollers being arranged in front of and behind the belt pulley in a circulating direction of the belt (3) and applying a pretensioning force onto the belt,—a spring means (7) which is arranged between the tensioning levers and which moves the tensioning rollers towards each other, thereby generating the pretensioning force,—and a locking arrangement (11), by which the tensioning levers can be locked relative to each other in a position in which the tensioning rollers are moved away from each other, thereby reducing or canceling the pretensioning force. The generator arrangement also includes another locking means (15) by which one of the tensioning levers can be locked relative to the star | 12-24-2015 |
