Patent number: 8726755Abstract: In a shift lever device, a first-link is held at a permitting-position due to a release button being operated. Therefore, when a shift lever is operated from a “P” shift position, when a second-link is pushed toward a vehicle right side by the shift lever, even if a magnet is not energized, the second-link is rotated in a state where sliding of the first-link toward a vehicle right is impeded. Operation of the shift lever from the “P” shift position is thereby forcibly permitted. Here, the first-link is disposed at the permitting-position that is an initial-position, and, due to the release button being operated, the first-link is held at the permitting-position. Therefore, there is no need to move the first-link by operation of the release button, and the operation load and operation stroke of the release button can be made to be small.Type: GrantFiled: October 19, 2011Date of Patent: May 20, 2014Assignee: Kabushiki Kaisha Tokai-Rika-Denki-SeisakushoInventors: Shuji Nakamura, Hideaki Ito

Patent number: 8186241Abstract: A shifting device for an automatic transmission of a motor vehicle with a gear-shift lever, which can be moved in an automatic shift track to select gear-shift positions; with a locking mechanism for blocking the adjusting movements of the gear-shift lever into at least one gear-shift position and/or out of at least one gear-shift position; and with a release button arranged on the gear-shift lever to release the blocking action of the locking mechanism. An increased level of functional reliability can be achieved by establishing a drive connection between the release button and two blocking elements, which are arranged redundantly on the gear-shift lever with the freedom to move up and down, that an actuation of the release button produces a synchronous stroke of the two blocking elements, where each of the blocking elements cooperates with an arresting gate comprising gate sections assigned to the gear-shift positions.Type: GrantFiled: April 29, 2009Date of Patent: May 29, 2012Assignee: Dr. Ing. h.c.

Patent number: 8161837Abstract: An emergency release device for manual actuation of the parking lock of a shift-by-wire transmission. The emergency release device comprises a mechanical transfer device located between an emergency release actuator and the transmission and engages a pivoting lever mechanism arranged on a transmission shifting shaft. A characterizing feature of the emergency release device is that the pivoting lever mechanism comprises a primary pivoting lever connected to the transfer device, a secondary pivoting lever connected to the transmission and a unidirectional coupling element located between the primary and the secondary pivoting levers. The advantage of this device relates to reduced susceptibility to corrosion, wear and noise emission and easier correct adjustment of the transfer device during assembly, while a separate prestressing mechanism for the cable of the emergency parking lock release can be omitted.Type: GrantFiled: December 5, 2008Date of Patent: April 24, 2012Assignee: ZF Friedrichshafen AGInventors: Andreas Giefer, Ludger Rake

Patent number: 8156841Abstract: A manipulation lever connection structure for a vehicle eliminates a striking sound without losing an adjusting function of an adjustment nut. The manipulation lever connection structure for a vehicle includes an arm for operating a driving changeover device and for connecting a wire which extends from a manipulation lever to the arm. An adjustment bolt is mounted on a distal end of the wire with a joint slidably mounted on the adjustment bolt on an axis thereof. An adjustment nut for supporting the joint is fastened to the adjustment bolt. A pair of side plate portions, respectively, forming elongated holes which allow the joint to pass therethrough is mounted on the arm. The adjustment nut is inserted between the pair of side plate portions with a buffer cover being mounted on the adjustment nut with a clearance formed between the adjustment nut and the respective side plate portions.Type: GrantFiled: October 26, 2007Date of Patent: April 17, 2012Assignee: Honda Motor Co., Ltd.Inventors: Kazuhiro Yasuda, Koji Sato, Hideo Yanai

Patent number: 8145399Abstract: Method and arrangement for providing an electronic gear shift selector associated with an automatic mechanical transmission for a heavy vehicle. The gear shift selector includes a toggle switch for asserting at least one gear shift request, a counter receiving the at least one gear shift request, and a time delay for preventing communication of the at least one gear shift request from the counter until a predefined time period has passed. A method for communicating a collective gear shift request to a gear box includes asserting one or more gear shift requests with a gear shift selector, communicating the gear shift requests to a counter, determining the collective gear shift requests occurring within a predefined time period, communicating the gear shift requests occurring within the predefined time period to a gearbox.Type: GrantFiled: May 22, 2006Date of Patent: March 27, 2012Assignee: Volvo Lastvagnar ABInventors: Anders Lindgren, Anders Eriksson

Publication number: 20120067154Abstract: The present invention provides for a transmission shift assembly for a vehicle and methods of monitoring and controlling the same. The transmission shift assembly includes a transmission having a shift position member movable between a plurality of gear positions, an actuator configured to move the shift position between the gear positions, and a linkage coupled to the actuator and movable between a plurality of positions in response to movement of the actuator. The assembly further includes a controller to control the actuator, an ignition to receive a key, and at least one key sensor positioned within the ignition and configured to transmit a signal to the controller upon sensing removal of the key, the controller controlling the actuator to move the shift position member to a predetermined gear position upon receiving the signal from the key sensor that the key has been removed from the ignition.Type: ApplicationFiled: November 29, 2011Publication date: March 22, 2012Applicant: NEXTEER (BEIJING) TECHNOLOGY CO., LTD.Inventor: James E.

Publication number: 20120067155Abstract: An actuating device for selecting gear steps of a shift-by-wire gearshift transmission with a base housing, a selection lever, a mechanical transmission means for actuating the parking lock, and with a coupling element are arranged between the selection lever and the transmission means. The transmission means is selectively actuated by the coupling element only during selection and/or deselection of the parking lock position on the selection lever. The coupling element has an end which is linearly guided in a slot and an end which is pivotally guided in certain sections in the base housing. The coupling element and the selection lever are kinematically coupled with each other by way of a swivel support. The structure and the installation of the mechanical transmission linkage required for selectively actuating the transmission means to the parking lock can be simplified.Type: ApplicationFiled: July 7, 2010Publication date: March 22, 2012Applicant: ZF FRIEDRICHSHAFEN AGInventor: Berthold Grosse Kohorst
