Patent number: 8414404Abstract: In this damper mechanism, when small fluctuations in torque input to the damper mechanism occur, small hysteresis torque is produced as a result of pressure contact between a radial plate and a first friction section. Consequently, the small torque fluctuations can be damped between the radial plate and the first friction region of the damper mechanism and can be output to an input shaft. In addition, along the direction of relative rotation of an annular plate and the radial plate, the friction coefficients of the annular plate and the radial plate become larger as the torsion angles of both plates become larger. Therefore, even when torque fluctuations become large, the hysteresis torque can be produced in accordance with the magnitude of the torque fluctuations.Type: GrantFiled: November 6, 2009Date of Patent: April 9, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Tatsushi Takenaka, Yuichi Miwa, Taku Harada, Yoshimitsu Yokouchi, Takeshi Miyagawa, Koji Hayashi

Patent number: 8414441Abstract: To provide a control system for carrying out a speed change operation of a geared transmission mechanism continuously by controlling a continuously variable transmission mechanism. A continuously variable transmission mechanism configured to increase and decrease speeds of a first and a second output discs simultaneously, and a geared transmission mechanism configured to change a speed change ratio stepwise are connected in series. The output discs are connected individually with intermediate shafts. The control system is adapted to synchronize a rotational speed of a switching mechanism and a rotational speed of a member to be engaged with the switching mechanism, by tilting a rolling member when carrying out a speed change in the geared transmission mechanism thereby increasing a rotational speed of one of the intermediate shaft while decreasing a rotational speed of the other intermediate shaft (at steps S3, S4 and S5).Type: GrantFiled: April 23, 2009Date of Patent: April 9, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Hiroyuki Ogawa, Akira Murakami

Patent number: 8414442Abstract: Disclosed herein is a gear train of a multi-step transmission for a vehicle, which can shift gears among nine forward speeds and one reverse speed. The gear train realizes a desired level of multi-step change gear ratios and has a reduced number of sets of planetary gears to reduce the volume and length of the transmission, thus realizing a compact structure, thereby facilitating the installation of the transmission in the vehicle.Type: GrantFiled: December 11, 2011Date of Patent: April 9, 2013Assignee: Hyundai Motor CompanyInventors: Tae Seok Seo, Jong Sool Park, Hyuk Jun Lee

Patent number: 8414443Abstract: An automatic transmission including a double pinion planetary gear unit PG1, two single pinion planetary gear units PG2 and PG3 and six frictional elements (viz., six clutches) C1 to C6 is so constructed as to establish nine forward speeds and one reverse speed by simultaneously putting selected three of the six frictional elements C1 to C6 into their engaged condition. The frictional elements C1 to C6 are of a type including mutually rotatable friction plates that cause production of an oil dragging resistance when the frictional element is under idling condition. With the simultaneously engaged condition of the three frictional elements, each speed is established with a reduced friction loss of the automatic transmission.Type: GrantFiled: June 13, 2011Date of Patent: April 9, 2013Assignee: Jatco LtdInventors: Kazuaki Aota, Yukiyoshi Inuta, Akihiro Yamamoto, Takayuki Okuda, Joerg Mueller, Rico Resch, Mirko Leesch

Patent number: 8414446Abstract: A multi-stage transmission (1) having a housing (9), a drive shaft (AN), an output shaft (AB), four planetary gear sets (RS1, RS2, RS3, RS4) each having first, second and third elements, at least eight rotatable shafts (1, 2, 3, 4, 5, 6, 7, 8), six shift elements, comprising four clutches (K1, K2, K3) and two brakes (B1, B2, B3). Selective engagement of the clutches and brakes results in different transmission ratios between the drive shaft (AN) and the output shaft (AB) so that up to nine forward gears can be implemented. The multi-stage transmission is delimited by the connections of the individual elements to each other and in that exactly three of the six shift elements are engage for gear step of the transmission.Type: GrantFiled: August 19, 2011Date of Patent: April 9, 2013Assignee: ZF Friedrichshafen AGInventors: Stefan Beck, Gerhard Gumpoltsberger, Hans-Peter Freudenreich

Patent number: 8414447Abstract: A transmission device for distributing drive torque between two output shafts. The device comprises three planetary gearsets (2, 3, 11). An input shaft is connected to a first element of gearsets (2, 3). The output shafts each couple a second element of gearsets (2, 3). A third element of gearset (2) couples a first element of gearset (11) and is connectable, via brake (14), to the housing. A third element of gearset (3) is connectable, via brake (17), to the housing and, via a claw shifting element (24), to a second element of gearset (11). A third element of gearset (11) couples the housing. Claw shifting elements (24, 18) couple the brakes (14, 17) such that, to engage brakes (14, 17), the claw shifting elements are first coupled to the first element of gearset (11) or the third element of gearset (3), and then the brakes are engaged.Type: GrantFiled: December 22, 2011Date of Patent: April 9, 2013Assignee: ZF Friedrichshafen AGInventor: Thomas Rosemeier
