System, method, and apparatus for operating a high efficiency, high output transmission
A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. A controller controls the shift actuator utilizing an actuating pulse and an opposing pulse.
ACTUATING DEVICE FOR AN AUTOMATED MANUAL TRANSMISSION
An actuating device (10) for an automated manual transmission (12) includes a pressure-medium-operated actuator (54) having a piston (58) and a piston rod (64) connectable to the selector element or shift element of the manual transmission. The piston is arranged in a cylindrical receiving chamber (50) of the housing (18) of the actuator and is coaxially movable therein. A sensor system (30)includes a magnet (38) arranged on a holding device (44) and a magnetic-field-sensitive sensor (32) is arranged on the housing radially with respect to the magnet (44).The holding device has a hollow cylindrical geometry, an anti-rotation element (80)is form-lockingly accommodated in an associated recess in the housing (18), and that the anti-rotation element extends across the holding device in the manner of a secant such that rotational movement of the holding device is blocked, although axial and rotational movement of the piston are possible.
Rotary Shifter Assembly
A rotary shifter assembly for changing gears in a vehicle transmission includes a shaft (16) that is rotatably supported in a housing (12) and movable between radial positions for indicating a gear change. A shift knob (10) is coupled to a first end of the shaft for actuation by a user. A plurality of flexible locking fingers (40) extend from the second end, and an overload wheel (18) is disposed about the fingers. The fingers engage the wheel to couple it with the shaft for concurrent rotation. A locking mechanism (64) engages the wheel to selectively prevent and allow concurrent rotation of the wheel and shaft during normal operation. The fingers move relative to the wheel to permit temporary rotation of the shaft relative to the wheel when a force applied to the shaft is beyond a maximum torque threshold, and automatically return to concurrent rotation with the wheel once the force is below the threshold.
SELECTOR DEVICE FOR A USER INPUT FOR SHIFTING A VEHICLE GEARBOX, AND GEARBOX SYSTEM FOR A VEHICLE
A selector device for a user input for shifting a vehicle transmission may be connected to the vehicle transmission for signal transfer. The selector device may include a slider unit coupled to a selector knob for the user input, and a housing unit for receiving the slider unit. The slider unit may be moveable in relation to the housing unit in a translatory manner. The selector device may have a ball bearing unit, where the ball bearing unit is designed to guide the slider unit linearly in the housing unit.
Clutch control for a high efficiency, high output transmission having improved response and position control
A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. A shift control circuit operates a shift actuator using a first opposing pulse command and a first actuating pulse command, and releases pressure with shift actuating and opposing volumes of the shift actuator upon determining a shift completion event.
Shift bracket
The present disclosure relates to a shift bracket that is coupled to a top plate of a cover panel for covering a floor tunnel and to which a shift lever unit is attached on an upper side. The shift bracket includes: a base plate to which the shift lever unit is attached; and a front leg portion and a rear leg portion that are coupled to the base plate and the top plate of the cover panel and hold the base plate with a space being provided upward in a vehicle vertical direction from the top plate. An ECU is disposed in the space between the top plate of the cover panel and the base plate.

Shift system theft protection feature
A steering column assembly includes a jacket assembly, a modular shift assembly, and a mounting bracket. The jacket assembly extends along a first axis. The modular shift assembly includes a shift bracket and a shift gate. The shift bracket is connected to the jacket assembly and defines a shift bracket opening. The shift gate is disposed on the shift bracket. The bracket defines a shift gate opening as well as first and second detents that extend from the shift gate opening. The mounting bracket is disposed on the shift bracket and has a tab that overlaps a portion of the shift gate.

SHIFT DEVICE
In a shift device, as a result of a rotor cam being rotated in a positive direction, and transmitting surfaces of the rotor cam pressing rotation surfaces of an urging cylinder, the urging cylinder is rotated in the positive direction, and a lever is moved rotationally towards a front side. Here, in a case in which a load towards the rear side is applied to the lever, the rotation surfaces are rotated in an opposite direction relative to the transmitting surfaces. As a result, the load towards the rear side being applied to the lever can be released.
