Patent number: 10415680Abstract: A differential apparatus includes: a differential mechanism that distributes an input driving force to a pair of side gears so as to allow differential motion therebetween; a differential case that accommodates the differential mechanism; and a clutch mechanism that transmits the driving force between the differential case and pinion shafts of the differential mechanism. The clutch mechanism includes: a slide member that is movable relative to the pinion shafts of the differential mechanism in the axial direction of the differential case and is non-rotatable relative thereto in the differential case; and an actuator that applies an axial moving force to the slide member. The slide member has on one end portion a first meshing portion. The differential case includes a disc-shaped first case member and a bottomed-cylindrical second case member that accommodates the differential mechanism. The second case member has a second meshing portion facing the first meshing portion.Type: GrantFiled: July 10, 2017Date of Patent: September 17, 2019Assignee: JTEKT CORPORATIONInventors: Tadashi Yoshisaka, He Jin, Yasunori Kamitani

Patent number: 9328778Abstract: The present device is an improved clutch system that conveys rotational energy from a power source to the gearbox input shaft of a motorcycle. A clutch basket is mechanically coupled to the power source and slidably engaged to pronged clutch drive plates, which are frictionally engaged to splined steel driven plates. Pressurized air moves a piston against a pressure plate, causing the clutch hub and splined steel driven plates to engage. The rotating splined steel driven plates will then rotate the clutch hub to convey rotational energy to the gearbox input shaft of the motorcycle.Type: GrantFiled: June 9, 2014Date of Patent: May 3, 2016Inventor: Todd Patterson

Patent number: 9151333Abstract: A transmission clutch including: a carrier; a clutch pack; friction plates; a compression plate including a portion; and a first ramp ring including: a first portion in contact with the portion of the compression plate; and a second portion. The clutch includes a second ramp ring including a third portion axially aligned with the second portion; a lever spring; and a piston. The piston displaces the spring in an axial direction such that: the spring applies a force to the second portion; the first ramp ring rotates in a circumferential direction and axially displaces in the axial direction; and the first ramp ring urges the compression plate in the axial direction to contact the clutch pack. The piston displaces the lever spring further in the axial direction such that the compression plate clamps pressure plates and friction plates in the clutch pack to rotationally fix the carrier to the housing.Type: GrantFiled: December 11, 2013Date of Patent: October 6, 2015Assignee: Schaeffler Technologies AG & Co. KGInventors: Jeffrey Hemphill, Philip George

Publication number: 20130270052Abstract: The present invention provides a controllable composite clutch having limited torque while being in a released state, in which a clutch capable of being controlled for performing engaging/releasing function and a physical limited torque device having relatively smaller torque being axially installed between an input/output shaft and an output shaft, or being radially installed between an input shaft and a cylindrical outputting rotation part; so when the clutch is controlled to be in an engaged state, the rotary kinetic energy between the input shaft and the output shaft is transferred through the clutch; when the clutch is controlled to be in a released state, the physical limited torque device performs limited torque coupling, such that the rotary kinetic energy between the input shaft and the output shaft can continue to be transferred and the slip rotational speed differential is generated due to over-torque can be carried out by smaller set torque.Type: ApplicationFiled: April 10, 2013Publication date: October 17, 2013Inventor: Tai-Her Yang

Patent number: 7921976Abstract: The invention relates to an overload protection device which has a force-loaded or torque-loaded component, a chamber for receiving a fluid which is at a predetermined pressure, and at least two transmitting elements which are connected to said component in a force-transmitting manner. The transmitting elements serve to transmit a counter-force or a counter-torque, which is generated by the pressure acting upon said transmitting elements, to the component, and is, at the same time, part of a sealing arrangement which occludes an outlet of the chamber due to the fluid pressure. If the force or torque acting upon the component are greater than the counter-force or counter-torque resulting from the predetermined pressure, the sealing arrangement unblocks the outlet, as a result of which the pressure in the chamber drops below said predetermined pressure.Type: GrantFiled: February 8, 2008Date of Patent: April 12, 2011Assignee: Airbus Deutschland GmbHInventors: Sam Tran, Bodo Wagner, Stephan Koch, Siegfried Rotthäuser

Patent number: 6974009Abstract: A control apparatus for a power train including a continuously variable transmission and a clutch arranged in series with the continuously variable transmission is provided in which an engaging pressure of the clutch is first reduced until a slip occurs, and is then increased after detection of the slip so as to re-engage the clutch, and an engaging pressure of the clutch to be established is calculated by giving an excess pressure to the engaging pressure at which the clutch is re-engaged, such that an excess amount of the transmitted torque of the clutch is set smaller than that of the continuously variable transmission. The control apparatus is adapted to determine a learned value as a correction value of the engaging pressure that is set in advance in accordance with an input torque applied to the clutch, based on the engaging pressure calculated by giving the excess pressure to the engaging pressure at which the clutch is re-engaged.Type: GrantFiled: February 3, 2003Date of Patent: December 13, 2005Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kazumi Hoshiya, Yasunori Nakawaki, Kunihiro Iwatsuki, Yasuhiro Oshiumi

Patent number: 6874606Abstract: A torque limiting clutch or coupler is provided for implementation between input and output shafts. A spring biased friction stack assembly establishes a characteristic breakaway torque of the unit. A torque modifying plate is fixed to a pressure plate and, in conjunction with an end plate, defines a ring-like cavity having a bladder therein filled with a fluid. As the torque limiting clutch or coupler begins to rotate, the fluid within the bladder is forced outwardly by centrifugal force and, as the speed increases, the restriction on the fluid radially causes it to begin to move axially, causing the pressure plate to act against the spring bias in one embodiment and to supplement the spring bias in another embodiment, regulating the characteristic breakaway torque as a function of rotational speed.Type: GrantFiled: October 30, 2003Date of Patent: April 5, 2005Assignee: Power Transmission Technology, Inc.Inventor: David C. Heidenreich

Patent number: 6378679Abstract: The invention concerns a clutch (10), comprising a clutch disk (22) connected with a first shaft (A) and a brake device (17) connected with a second shaft (B). By means of the brake cylinder (19) of the brake device (17), the brake pad (18) can be coupled into engagement with the clutch disk (22), in which case a movement of rotation between the shafts (A and B) is prevented. In the solution of equipment, between the shaft (A) and the shaft (B), there is a support bearing (21), which supports the movement of rotation between the shafts (A and B) when the clutch is supposed to slip. According to the invention, in the pressure line (59), there is a holding pressure maintained by means of accumulators (100), which holding pressure determines the torque at which the clutch slips.Type: GrantFiled: April 24, 2000Date of Patent: April 30, 2002Assignee: Suokone OyInventors: Jouni Karjalainen, Eero Juppi
