Patent number: 5537885Abstract: A gear shift mechanism particularly suited for a drag racing car is disclosed that causes the gear shifts of a transmission to be sequenced upon the attainment of selectable predetermined conditions so that the drag racing car obtains its desired acceleration in an optimum manner. The gear shift mechanism comprises electrically or pneumatically operated cylinders that move the gear shift lever upon sensing optimum conditions related to the acceleration performance of the drag racing car. The cylinders are positioned on opposite sides of the gear shift lever and provide counter-forces during shifting through at least one gear and yet allow the gear shifting to preferably be accomplished in a single direction. The counter-acting cylinders eliminate overshooting of the gear shift lever during movement of the lever arm. Alternatively, manual input instead of predetermined conditions may be substituted into the gear shift mechanism.Type: GrantFiled: August 4, 1994Date of Patent: July 23, 1996Inventor: Gerald A.

Patent number: 5226303Abstract: A locking arrangement between a selector lever of a transmission and an ignition lock of a motor vehicle has a locking pawl, which is rotatably disposed in a selector lever block. The locking pawl, via a recess, form-lockingly reaches around a cam part arranged on the selector lever. When the selector lever is in the parking position, the cam part is rigidly connected with a button that is to be operated manually. In this case, a catch hook of the locking pawl engages into the moving path of a locking cam, which is arranged on the selector-lever-side end of a flexible linkage. The catch hook acts in a blocking manner, as long as the button is operated into a first position. When the button is not operated, the ignition lock, which by way of the linkage is connected with the locking cam, can be rotated into an inoperative position, whereby the locking cam fixes the locking pawl. The button cannot then be operated because the cam part is fixed by the recess.Type: GrantFiled: June 19, 1992Date of Patent: July 13, 1993Assignee: Dr. Ing. h.c.F.

Patent number: 5086870Abstract: A remotely controlled system for the operation of a vehicle wherein a limited physical input is translated into desired vehicle movement. The invention uses a unitary manipulator with two axes of movement to direct the steering, acceleration and braking functions of the vehicle. The surplus current available from the main battery of the vehicle powers the control system. The steering function of the invention involves the conversion of a mechanical input into a frequency-based signal which is processed by a primary steering microprocessor. This microprocessor in turn directs a frequency-based motor controller to operate a motor which rotates a steering shaft of the vehicle. The acceleration and braking functions operate in the same way, wherein a primary acceleration microprocessor acts upon a frequency-based signal to direct a frequency-based motor which is connected to the accelerator and brake pedals of the vehicle.Type: GrantFiled: October 31, 1990Date of Patent: February 11, 1992Assignee: Division Driving Systems, Inc.Inventor: Scott Bolduc

For disengaging the clutch before shifting operations, an unloader valve is provided which is actuated by moving a speed change lever along a direction other than the key-shifting direction.Relief valve means also acting as an unloader valve for disengaging the clutch is disclosed. Differential-locking clutch is also disclosed which is operated by fluid for actuating the clutch in the transmission path.Type: GrantFiled: May 20, 1986Date of Patent: June 16, 1987Assignee: Kanzaki Kokyukoki Mfg. Co., Ltd.Inventors: Kojiro Yamaoka, Hideaki Okada

Patent number: 4671378Abstract: The present invention relates to a mechanism for maintaining a gear shift control lever in a neutral position against inadvertent and accidental movement. The mechanism includes a control lever unit movable in a first plane to effect operation of a cable connected to the vehicle transmission direction control valve. The control lever is also movable in a second plane normal to the first plane but with linkage effecting lost motion in the second plane movement with respect to the transmission direction control valve cable. A bracket mounted side-by-side with the control lever linkage is operably connected to the transmission gear selector valve and has a lost motion connection with the control lever such that the bracket is moved only upon movement of the control lever in the second plane.Type: GrantFiled: January 21, 1986Date of Patent: June 9, 1987Assignee: Deere & Co.Inventors: Steven G. Korrect, Robert L. Kaukaskie

Patent number: 4646870Abstract: The invention relates to a remote control device of a gear-box for motor vehicles with incorporated compressed-air system. A gear-shifting gate with servo-pneumatic control provided at the gear-box for setting the gears comprises substantially two working cylinders controlled by servo-valves whose travels are signalled via position indicator switches. A gearshift lever console in the driver's cabin transmits the shifting commands via position indicator switches to electronic control means which in turn control the gear-shifting gate at the gear-box. For feeding back to the gearshift lever the shifting states prevailing at the gear-box, a working cylinder is provided in the gearshift lever console which acts directly on the gearshift lever via a mechanical link.Type: GrantFiled: May 9, 1985Date of Patent: March 3, 1987Assignee: Wolf-Dieter GoedeckeInventors: Siegfried Koch, Jurgen Adams, Wolf-Dieter Goedecke

Patent number: 4629206Abstract: A reverse lock-out control employing a bracket fixed to the handle bar of a vehicle and associated with a brake lever pivotly mounted to that bracket. The device includes a control lever pivotly mounted to the bracket adjacent the brake lever. A pin is slidably associated with the brake lever and a hole is provided in the control lever such that the brake lever and control lever may be engaged by the pin when the brake lever is in the off position. The control lever is linked to a reverse gear lock-out such that with the pin engaged, application of the brake will result in actuation of the lock-out mechanism.Type: GrantFiled: March 22, 1985Date of Patent: December 16, 1986Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Masaharu Omagari, Tsuneo Kazikawa, Takahumi Suzuki

Patent number: 4582161Abstract: In a remote control arrangement for a vehicle gearbox, the gearbox is mounted in a chassis frame and is controlled by a gear-change lever articulately connected, via a remote control rod, to a gear selection shaft on the gearbox. In a bus with rear-mounted engine and gearbox for example, such an arrangement includes a comparatively long remote control rod, usually mounted in the chassis frame. However, large relative movements between gearbox and chassis frame have caused disturbances in the control of the gearbox. This problem is solved by the gear selection shaft comprising two mutually articulatedly connected shafts, of which an outer shaft is connected via a spherical mounting to a support structure articulately attached to the chassis frame. Unintentional disengagement of an engaged gear is thus prevented.Type: GrantFiled: February 6, 1984Date of Patent: April 15, 1986Assignee: Saab-Scania AktiebolagInventor: Sven G. B. Nilsson
