Patent number: 8051956Abstract: A driving device for a parking brake system includes a casing shift member, a brake cable and a driving member. The casing shift member includes a cable casing. The brake cable is mounted through the cable casing. The driving member has a driving unit connected to and driving the casing shift member to perform a longitudinal motion. Thus the cable casing applies a force on the brake cable so as to perform a brake work. Because the brake cable is tightened with the force provided by the cable casing, the brake cable is only bent slightly. Thus the curvature of the brake cable is small. That prevents the brake cable from being damaged and prolongs a life span of the brake cable. Moreover, a mechanical efficiency of the driving device is improved because the brake cable is tightened with the force provided by the cable casing.Type: GrantFiled: June 3, 2008Date of Patent: November 8, 2011Assignee: Automotive Research & Testing CenterInventors: Chien-Tai Huang, Chien-Tzu Chen, Shou-Ti Cheng, Bo-Ruei Chen, Ming-Hu Huang

Publication number: 20100218633Abstract: A bicycle shifting control apparatus controls an electrical power supplied from a power supply to first and second gear shifting devices that are operated by first and second gear shift operating devices, respectively. The bicycle shifting control apparatus includes a first power supply sensor and a controller. The first power supply sensor detects a power level of the power supply. The controller receives a power level signal from the first power supply sensor. The controller performs a stopping operation of the first gear shifting device in response to the first power supply sensor detecting the power level of the power supply being below a first prescribed power level, but the controller transmits a second gear shift signal from the second gear shift operating device to the second gear shifting device to perform a second shifting operation of the second gear shifting device.Type: ApplicationFiled: March 2, 2009Publication date: September 2, 2010Applicant: Shimano Inc.Inventors: Tadashi ICHIDA, Takumi ONOGI, Kazuhiro FUJII, Masahiko FUKUDA, Haruyuki TAKEBAYASHI, Ryuichiro TAKAMOTO

Publication number: 20100212447Abstract: A shifting device is provided for a vehicle transmission with a selector lever pivotable within a shifting device housing about at least one axis of rotation for selecting gears defined within the vehicle transmission. A shift position of the selector lever is assigned to at least one gear. A locking device for the individual shift positions of the selector lever can be released as a function of given general data of the state of motor vehicle components such as the pedal mechanism and the engine. The locking device has a locking element displaceable by the selector lever analogously to the individual shift positions of the selector lever. The locking element has a plurality of locking devices, which correspond to the individual shift positions and which can be brought into a locking position and an unlocking position by at least one actuating device.Type: ApplicationFiled: January 11, 2006Publication date: August 26, 2010Inventors: Andreas Giefer, Jörg Meyer

Patent number: 7761254Abstract: A machine having an operator interface for requesting an action from an actuator of the machine includes a movable component of the operator interface. The movable component is movable among at least two positions. One of a magnet and a Hall effect sensor is positioned to move in response to movement of the movable component. The other of the magnet and the Hall effect sensor has a stationary position relative to the movable component. A pulse width modulator is operably coupled to the Hall effect sensor for producing a first pulse width modulated signal. The first pulse width modulated signal is altered in response to movement of one of the Hall effect sensor and the magnet relative to the other. An electronic controller is in communication with the pulse width modulator and the actuator and is configured to actuate the actuator in response to evaluation of the first pulse width modulated signal.Type: GrantFiled: May 11, 2007Date of Patent: July 20, 2010Assignee: Caterpillar IncInventors: Stephen Fouts, Matthew Vande Wiele, Rex Glover, Curtis Johnson, Kenneth Her, Roger Obourn, Dan Shearer

Publication number: 20100175494Abstract: An electronic selector lever module for generating gear shifting signals for an automatic transmission of a vehicle. The swivel motion of the gear selector lever, within a main shifting path, is transformed into rotational motion for an angle sensor. The sensor is positioned on a printed circuit board and is actuated by a rotor. To guide the rotor relative to the angle sensor, the rotor either surrounds a rounded part of the printed circuit board or surrounds a rotor guidance which is mounted on the printed circuit board. The mechanical linking point is a short sleeve at a slider, which both belong to the rotor, needed for the shifting path motion, and which also drive the tilting lever for the transverse motion. The slider can be moved, relative to the rotor, along rails, either radially and directly at the rotor, or tangentially to the pivot point of the rotor.Type: ApplicationFiled: July 11, 2008Publication date: July 15, 2010Applicant: ZF FRIEDRICHSHAFEN AGInventors: Thomas Schober, Thomas Deichler, Hans-Ludwig Gotz
