Patent number: 7026780Abstract: The invention concerns a method for stabilizing the motion of an articulated chain of a chain block, especially to prevent the formation of resonance oscillation of the chain, in which an articulated chain is led across a polygonal chain wheel with non-uniform pitch, which is driven by an electric motor. In order to create a method to prevent the formation of a resonance oscillation of the articulated chain, it is proposed that a periodic and/or stochastic and dampening actuating variable is superimposed on the velocity of the chain wheel (4) and the dampening actuating variable produces a change in the chain velocity so as to prevent a formation of a resonance oscillation. The chain drive with reduced polygon effect is characterized in that an electronic damper (8) is hooked up in front of the electric motor (2), which produces a control of the electric motor (2) such that a formation of a resonance oscillation of the articulated chain (5) is prevented.Type: GrantFiled: March 31, 2004Date of Patent: April 11, 2006Assignee: Demag Cranes & Components GmbHInventors: Eberhard Schröder, Giuliano Persico

Publication number: 20020041167Abstract: There is provided a driving force control system for a front-and-rear wheel drive vehicle, which is capable maintaining an optimum slip condition of the drive wheels even on a low-friction road surface, ensuring a proper grip of rear wheels even on a low-friction road surface or a downhill slope, even when the driver operates the steering wheel while the vehicle is performing decelerating travel on such a road, and smoothly performing the assistance of an electric motor when the vehicle is accelerated without developing a torque step, thereby ensuring stable traveling and excellent acceleration and drivability. The front-and-rear wheel drive vehicle drives the front wheels by an engine, and rear wheels by an electric motor via an electromagnetic clutch. The target driving force for driving the vehicle is calculated based on at least a vehicle speed and an accelerator pedal opening. The present traveling condition of the vehicle is determined.Type: ApplicationFiled: July 17, 2001Publication date: April 11, 2002Applicant: HONDA GIKEN KOGYO KABUSHIKI KAISHAInventors: Kazuhiko Kitano, Toshihiko Fukuda, Takahiro Yonekura, Naoki Uchiyama, Kenji Honda, Tooru Nakasako

Patent number: 6211630Abstract: An automotive HVAC system controls two side by side film belts with a single drive motor. Two co planar wind up rollers, one for each belt, have inboard ends that are indirectly connected by a rotation transmission means that has a defined level of turning “slack”. Rotation is transmitted from one wind up roller to the other only after the slack has been taken up, allowing a certain degree of offset between the two belts. When a first belt is turned past a first position, it eventually moves the other belt to a new position, with the defined belt offset maintained. The first belt can then be turned back, breaking the indirect connection between the two shafts.Type: GrantFiled: February 9, 2000Date of Patent: April 3, 2001Assignee: Delphi Technologies, Inc.Inventor: Donald John Enzinna
